Description

  The present invention relates to a system that supports alignment of a plurality of objects.

  When a person tries to align the positions of a plurality of objects, in many cases, the person performs a visual alignment based on information held by the person. Here, “matching” the positions of a plurality of objects means that the distance between any two objects selected from the plurality of objects is made smaller than a predetermined threshold value. However, if a person visually aligns the positions of a plurality of objects, it may happen that the positions of the wrong objects are aligned due to a person's mistake in viewing.

  Hereinafter, the connection between connectors will be described as an example of aligning the positions of a plurality of objects.

  Here, it is assumed that a certain device includes a large number of connectors and a connector connected to a bundle of cables is connected to the connector. In that case, the worker proceeds with the connection work, for example, relying on a symbol or the like written on a tag or the like installed on the connector or cable. However, there are cases where a space for describing a symbol or the like in a tag or the like is limited, and there are cases where connectors that should not be connected by mistake are connected. In that case, not only does the device not operate, but a malfunction that adversely affects the user of the device may occur, and in some cases, there is a risk of damage to the device.

  As a method for solving this problem, the method disclosed in Patent Document 1 reads the RFID identification ID of an object and sends it to a computer. And a computer shows the method of showing the work procedure corresponding to the input identification ID data from the RFID information which matched identification ID and RFID. Here, RFID is an abbreviation for radio frequency identifier. Also, ID is an abbreviation for identifier.

  On the other hand, in relation to the present invention, Non-Patent Document 1 discloses distance measurement using radio wave intensity. Further, in relation to the present invention, Non-Patent Document 2 discloses an RFID including a light emitting unit.

  However, the method disclosed in Patent Document 1 requires an operator to read RFIDs of an object one by one with a reader. Therefore, the method disclosed in Patent Document 1 has a problem that the amount of work and the work time by the worker are large.

  An object of the present invention is to provide a support system that can reduce misalignment by a person and reduce the amount of work and time of alignment by a person.

  The support system of this invention is provided with the 1st support part provided in the 1st goods, the 2nd support part provided in the 2nd goods, and the control part. The control unit obtains distance difference information representing a difference in distance from each of the first support unit and the second support unit by wireless communication with the first support unit and the second support unit. And a control part outputs the signal according to this rejection determination result of the predetermined condition regarding the said distance difference information.

  The support system or the like according to the present invention can reduce misalignment by a person, and can reduce the work amount and work time of the alignment by a person.

First, an example in which the support system of the present invention is applied to connection between connectors will be described.
<First embodiment>
1st embodiment is embodiment regarding the assistance system which assists the connection of connectors by changing the output to an output part.
[Configuration and operation]
FIG. 1 is a conceptual diagram showing the configuration and operation of a support system 191a that is an example of the support system of the first embodiment.

  First, a configuration example to which the support system 191a can be applied will be described.

  In FIG. 1, the connector 101a and the connection part 211a provided in the connector 101a are shown together. FIG. 1 also shows the connector 102a and the connecting portion 212a included in the connector 102a.

  The connector 101a is a connector in which the position of the connector 101a can vary depending on the user of the connector 101a. The connector 102a is a connector whose position can be changed by a user of the connector 102a.

  The connector 101a is a connector that can be electrically connected to another connector.

  The connector 101a and the connector 102a can be estimated. Here, the “estimated connection” refers to a connection that can be estimated by the worker as being connected. The estimated connection is, for example, a state in which the connection portion 211a and the connection portion 212a are fitted when either the connection portion 211a or the connection portion 212a can be fitted to the other. Is a connection confirmed by appearance. The presumed connection is a connection regardless of whether or not the joining on the electric signal between the terminals (not shown) constituting the two connectors is correct. In the following, a connection in which the electrical signal joining between the terminals constituting the two connectors is correct is referred to as an “actual connection”.

  The estimated connection between the connection unit 211a and the connection unit 212a may be an actual connection or may not be an actual connection.

  Next, the support system 191a will be described.

  The support system 191a is a system that supports connection between the connector 101a and the connector 102a performed by an operator.

  The support system 191a includes a support unit 151a, a support unit 152a, and a control unit 161a.

  The control unit 161a includes a communication unit 123a, a recording unit 113a, and a processing unit 181a.

  The support unit 151a is installed in the connector 101a. The support unit 151a includes a recording unit 111a, a communication unit 121a, an output unit 131a, and a processing unit 182a.

  The support unit 152a is installed in the connector 102a. The support unit 152a includes a recording unit 112a, a communication unit 122a, and a processing unit 183a.

  The communication unit 123a of the control unit 161a can communicate with each of the communication unit 121a of the support unit 151a and the communication unit 122a of the support unit 152a. Then, the communication unit 123a causes the recording unit 113a to record information obtained through communication with each of the communication unit 121a of the support unit 151a and the communication unit 122a of the support unit 152a. The information obtained by the communication unit 123a communicating with the communication unit 121a includes information described later necessary for the processing unit 181a to derive a value representing the distance between the control unit 161a and the support unit 151a. included.

  Hereinafter, a value representing a distance is referred to as a “distance value”. The distance value may be a value proportional to the distance, for example. The distance value may be a value obtained by adding a predetermined constant to a value proportional to the distance, for example.

  Further, information obtained by the communication unit 123a communicating with the communication unit 122a includes information described later necessary for the processing unit 181a to derive the distance value between the control unit 161a and the support unit 152a. included.

  The communication unit 123a causes the recording unit 113a to record information necessary for deriving the distance value with each of the support units 151a and 152a via the processing unit 181a.

  The recording unit 113a of the control unit 161a records in advance information including a condition regarding the difference between the distance value between the support unit 151a and the control unit 161a and the distance value between the support unit 152a and the control unit 161a. Yes. The condition is, for example, a condition that the difference is smaller than a threshold value Vt1. The recording unit 113a also records information instructed by the processing unit 181a to the recording unit 113a. The recording unit 113a also reads information instructed by the processing unit 181a to the recording unit 113a and sends the information to the communication unit 123a or the processing unit 181a.

  The processing unit 181a of the control unit 161a is necessary for deriving a distance value between the control unit 161a and each of the support units 151a and 152a that is recorded in the recording unit 113a via the processing unit 181a. Information is read from the recording unit 113a. Then, the processing unit 181a derives a distance value between the control unit 161a and the support unit 151a from information necessary for deriving a distance value between the control unit 161a and the support unit 151a. The processing unit 181a causes the recording unit 113a to record information representing the derived distance value between the control unit 161a and the support unit 151a.

  Further, the processing unit 181a derives a distance value between the control unit 161a and the support unit 152a from information necessary for deriving a distance value between the control unit 161a and the support unit 152a. The processing unit 181a causes the recording unit 113a to record information representing the derived distance value between the control unit 161a and the support unit 152a.

  Next, the processing unit 181a reads information including the condition from the recording unit 113a. Here, the condition is a condition set for a difference between a distance value between the support unit 151a and the control unit 161a and a distance value between the support unit 152a and the control unit 161a.

  The processing unit 181a reads the derived difference between the distance value between the control unit 161a and the support unit 151a and the distance value between the control unit 161a and the support unit 152a from the recording unit 113a. It is determined whether or not the above condition is satisfied.

  When it is determined that the difference satisfies the condition, the processing unit 181a sends instruction information to the communication unit 121a of the support unit 151a via the communication unit 123a. The instruction information is instruction information including an instruction for changing the output of the output unit 131a of the support unit 151a.

  The recording unit 111a of the support unit 151a records identification information that can identify the support unit 151a.

  The communication unit 121a of the support unit 151a sends predetermined information to the communication unit 123a of the control unit 161a according to an instruction from the processing unit 182a. Further, the communication unit 121a sends the information sent by the communication unit 123a of the control unit 161a to the processing unit 182a.

  The processing unit 182a causes the communication unit 121a to send predetermined information to the communication unit 123a of the control unit 161a. When the processing unit 182a causes the communication unit 121a to send information to the communication unit 123a of the control unit 161a, the processing unit 182a adds the identification information of the support unit 151a read from the recording unit 111a to the information transmitted by the communication unit 121a. Let

  The processing unit 182a also processes information sent from the communication unit 121a. For example, when the communication unit 121a receives certain instruction information sent by the communication unit 123a of the control unit 161a, the processing unit 182a transmits information on the content instructed by the communication unit 123a from the communication unit 121a to the communication unit. 123a is sent. Further, for example, when the communication unit 121a receives other instruction information sent from the communication unit 121a to the communication unit 121a by the communication unit 121a, the processing unit 182a follows the instruction of the other instruction information. The output unit 131a is caused to change the output. The change of the output includes starting a new output by the output unit, stopping the output already performed by the output unit, or changing the output already performed by the output unit to another output. It is.

  When the processing unit 182a instructs to change a predetermined output, the output unit 131a changes the output. The change is a change for causing the worker to recognize the change. The change is, for example, a change for indicating to the operator that the connection unit 211a and the connection unit 212a should be connected. Alternatively, the change is, for example, a change for indicating to the worker that the connection between the connection unit 211a and the connection unit 212a is an actual connection. Alternatively, the change is, for example, a change for indicating to the worker that the connection unit 211a and the connection unit 212a should not be connected. Alternatively, the change is, for example, a change for indicating to the worker that the connection between the connection unit 211a and the connection unit 212a is not an actual connection.

  Here, it is assumed that the output unit 131a includes a light emitting unit (not shown). In that case, the output unit 131a can change the output by switching the light emitting state of the light emitting unit. The output unit 131a can change the output depending on whether the light emitting unit emits light or turns off, for example. Further, for example, the change from the state in which the light emitting unit is turned off to the lighting state may be a change in output informing the operator that the connection unit 211a and the connection unit 212a should be connected. Alternatively, for example, the change from the state where the light emitting unit emits light to the extinguished state may be the change of the output. Or the output part 131a can also change the said output by changing the space | interval of light emission and light extinction, the color of light emission, etc. FIG.

  Further, for example, the output unit 131a includes a display unit (not shown), and the output can be changed by changing the display on the display unit. Further, for example, when the support system 191a prompts the worker to connect the connection unit 211a and the connection unit 212a, the output unit 131a changes the output to newly display the meaning of “connect”. You may go.

  Furthermore, the output unit 131a includes a sound generation unit (not shown), and can change the output by generating a sound generated by the sound generation unit. In the case where the output unit 131a includes the sound generation unit, the output unit 131a newly outputs a warning sound when, for example, the support system 191a suppresses the connection between the connection unit 211a and the connection unit 212a to the worker. The output to be emitted may be changed. Alternatively, in the case where the output unit 131a includes the sound generation unit, the output unit 131a may change the output to newly generate a sound with the meaning of “do not connect”, for example.

  In addition, the output unit may change the output by changing the stimulus to the operator such as vibration.

  The recording unit 112a of the support unit 152a records identification information that can identify the support unit 152a.

  The communication unit 122a of the support unit 152a performs communication with the communication unit 123a of the control unit 161a. Then, the communication unit 122a sends the information received from the communication unit 123a of the control unit 161a to the processing unit 183a. In addition, the communication unit 122a sends information instructed by the processing unit 183a to the communication unit 123a of the control unit 161a.

  The processing unit 183a processes information received from the communication unit 122a. For example, when the instruction information sent from the communication unit 123a of the control unit 161a to the communication unit 122a is received from the communication unit 122a, the processing unit 183a performs processing according to the instruction content of the instruction information. When the processing unit 183a causes the communication unit 122a to send information to the communication unit 123a of the control unit 161a, the processing unit 183a causes the communication unit 122a to add the identification information of the support unit 152a read from the recording unit 112a to the information.

  As a method of deriving the distance value between the control unit 161a and the support unit 151a performed by the control unit 161a, two methods described below can be used.

  The first method is a method in which a delay time when the control unit 161a communicates with the support unit 151a is a distance value between the control unit 161a and the support unit 151a.

  In the first method, the processing unit 181a of the control unit 161a sends instruction information to the communication unit 121a of the support unit 151a via the communication unit 123a. The instruction information is instruction information for instructing the communication unit 121a to send reply information indicating that the instruction information has been received to the communication unit 123a as soon as the instruction information is received. Then, the processing unit 181a obtains a delay time from the difference between the time when the communication unit 123a sends the instruction information and the time when the communication unit 123a receives the reply information. Then, the processing unit 181a uses the obtained delay time as a distance value. The delay time is a value obtained by adding the processing time of the processing performed by the communication units 121a and 123a to the time required for the radio wave by communication to reciprocate between the communication unit 123a and the communication unit 121a. Here, the time required for the radio wave due to communication to reciprocate between the communication unit 123a and the communication unit 121a is proportional to the distance between the communication unit 123a and the communication unit 121a because the speed of the radio wave due to communication is constant. . However, it is assumed that the radio wave travels linearly without reflection between the communication unit 123a and the communication unit 121a and that the air density in the space where the radio wave passes is constant. Further, the processing time of the processing performed by the communication units 121a and 123a can be regarded as constant because the processing content is determined. Accordingly, the delay time is a value obtained by adding a constant to a value proportional to the distance between the communication unit 123a and the communication unit 121a. The processing unit 181a may use a value obtained by processing the obtained delay time as the distance value. For example, the delay time is obtained by intentionally changing the distance between the communication unit 123a and the communication unit 121a, the processing time of processing performed by the communication units 121a and 123a is obtained from the delay time, and the processing time is calculated from the delay time. A value obtained by subtracting can be used as a distance value. In this case, the distance value is a value proportional to the distance between the communication unit 123a and the communication unit 121a.

  The second method for obtaining the distance value between the communication unit 123a and the communication unit 121a is a method in which the reception intensity at the control unit 161a of the radio wave sent from the support unit 151a to the control unit 161a is used as the distance value. Hereinafter, the reception intensity at the control unit 161a of the radio wave sent from the support unit 151a to the control unit 161a is referred to as “reception radio wave intensity”. In an ideal state, the received radio wave intensity is inversely proportional to the square of the distance between the support unit 151a and the control unit 161a. And when the distance of the support part 151a and the control part 161a is comparatively short, it will be in the state close | similar to an ideal state (refer nonpatent literature 1). Therefore, when the distance between the support unit 151a and the control unit 161a is relatively short, the received radio wave intensity can be used as the distance value. Even if it is not close to the ideal state, the received radio wave intensity is roughly reduced as the distance between the support unit 151a and the control unit 161a increases. Therefore, even if the distance between the support unit 151a and the control unit 161a is not so short, if the accuracy required for the distance value is not so high, the received radio wave intensity can be used as the distance value. The case where the accuracy required for the distance value is not so high is, for example, a case where there is no connector near the connector 101a other than the connector 101a for which the operator should determine whether or not the connector 102a can be connected.

  The description of the method for deriving the distance value between the control unit 161a and the support unit 152a by the control unit 161a is the same as the method for deriving the distance value between the control unit 161a and the support unit 151a. However, the support unit 151a is replaced with the support unit 152a, and the communication unit 121a is replaced with the communication unit 122a.

  Both of the pair of connectors to be connected may include an output unit similar to the output unit 131a of the connector 101a illustrated in FIG.

  For example, RFID can be used for the communication unit 121a, the recording unit 111a, and the processing unit 182a of the support unit 151a, or the communication unit 122a, the recording unit 112a, and the processing unit 183a of the support unit 152a. When an RFID is used for the support unit 151a, the RFID may be an active type that operates by supplying power from a power source, or a passive type that uses a radio wave transmitted from the communication unit 123a of the control unit 161a as a power source. An RFID with LED can also be used for the communication unit 121a, the recording unit 111a, the processing unit 182a, and the output unit 131a of the support unit 151a. Here, LED is an abbreviation for light emitting diode. In this case, the LED can be used as the output unit 131a. RFID with LED is disclosed in Non-Patent Document 2, for example. Non-Patent Document 2 discloses a passive type RFID with LED. When an output unit other than an LED is used as the output unit 131a, or when an LED is used and it is desired to brighten the LED for a long time or not, the radio wave transmitted from the communication unit 123a is not used as a power source, but to the output unit 131a. It is often better to supply power separately.

  The support system 191a shown in FIG. 1 is used by being incorporated into a connector and a connector connected to a cable, for example, as will be described below.

  FIG. 2 is a conceptual diagram illustrating a state in which the support system 191a illustrated in FIG. 1 is incorporated in a connector provided in the apparatus and a connector connected to a cable.

  A connector 101a including the support unit 151a is a connector included in the device 311a. The input / output unit 241a of the device 311a and a terminal (not shown) of the connection unit 211a are electrically connected by a wiring 251a. The input / output unit 241a supplies a signal, a power supply voltage, and the like to another device or the like via a connector having a connection unit 211a and another connection unit connected to the connection unit 211a and a cable connected to the connector. It is. Alternatively, the input / output unit 241a inputs a signal, a power supply voltage, or the like from another device or the like via a connector having a connection unit 211a and another connection unit connected to the connection unit and a cable connected to the connector. It is the part to receive.

  A terminal (not shown) of the connection portion 212a of the connector 102a in which the support portion 152a is installed is electrically connected to the cable wire 201a. It is assumed that the cable line 201a is electrically connected to another input / output unit of another device (not shown).

  The description of the support system 191a is the same as the description of the support system 191a illustrated in FIG.

  As illustrated in FIG. 2, when the support unit 151a is installed in the device 311a, power can be easily supplied from the device 311a to the support unit 151a. Therefore, it is easy to apply an active type RFID to the support unit 151a. In addition, the operation of the output unit 131a can be performed by power supplied from the device 311a. Therefore, an output unit with large power consumption can be used as the output unit 131a. For example, an LED that emits light with high brightness for a long time can be used for the output unit 131a.

  On the other hand, since the support unit 152a is provided in the connector 102a connected to the cable line 201a, it may be difficult to supply power to the support unit 152a. For example, when the cable line 201a is not connected to a configuration including any power source, it is difficult to supply power to the support unit 152a unless a battery or the like is separately provided. Therefore, when RFID is used for the support unit 152a, it may be preferable to use passive RFID.

The support system 191a obtains distance values between the support unit 151a included in the connector 101a and the support unit 152a included in the connector 102a and the control unit 161a from the acquired information. The acquisition information is acquisition information obtained by wireless communication between the support units 151a and 152a and the control unit 161a. Here, in the following, “acquired information” refers to information for deriving a distance value with each support unit. Then, the support system 191a derives the difference between the distance value between the support unit 151a and the control unit 161a and the distance value between the support unit 152a and the control unit 161a. When the difference between the derived distance values satisfies a predetermined condition, the support unit 151a indicates the change of the output to the worker. The change of the output by the support unit 151a is a change for indicating to the worker whether or not the connection between the connector 101a and the connector 102a is possible. Therefore, the operator can easily know whether or not the connector 101a and the connector 102a can be connected by changing the output. Therefore, the support system 191a can reduce errors in connection between connectors by an operator. Furthermore, the support system 191a can improve the efficiency of the work of connecting the connectors between the workers.
[Processing flow]
3 and 4 are conceptual diagrams illustrating an example of a processing flow of processing performed by the support system illustrated in FIG. In each process shown in FIGS. 3 and 4, the description on the left side of the colon (:) symbol represents the subject of the process. In each process shown in FIGS. 3 and 4, the description on the right side of the colon (:) symbol represents the contents of the process. Moreover, the code | symbol used in description of the following FIG.3 and FIG.4 is a code | symbol attached | subjected to each structure of the assistance system 191a shown in FIG.

  First, the processing unit 181a of the control unit 161a sets the threshold value VT1 as the processing of S101. The threshold value VT1 is a threshold value used in the process of S141 described later. The processing unit 181a performs setting of the threshold value VT1 based on, for example, input information from the outside.

  The processing unit 181a performs the processing of S111 and the processing of S121 after the processing of S101.

  As the processing of S111, the processing unit 181a causes the communication unit 123a to send instruction information to the communication unit 121a of the support unit 151a. The instruction information is instruction information with a content instructing the communication unit 121a to promptly send reply information to the communication unit 123a when the communication unit 121a receives the instruction information.

  And the communication part 123a sends the said instruction information with respect to the communication part 121a as a process of S112.

  And the communication part 121a sends the said instruction information which the communication part 123a sent to the process part 182a as a process of S113. And the communication part 121a sends the said reply information with respect to a communication part by the instruction | indication from the process part 182a.

  Next, the communication unit 123a receives the reply information sent by the communication unit 121a as the process of S114.

  And the communication part 123a sends the information showing the time which received the said reply information to the process part 181a as a process of S115.

  After the process of S112, the communication unit 123a sends, to the processing unit 181a, information indicating the time when the instruction information is sent to the communication unit 121a by the process of S112 as the process of S117.

  The processing unit 181a obtains the delay time TD1 from the time when the reply information is received and the time when the instruction information is sent. Here, the time when the reply information is received is the time when the communication unit 123a sent to the processing unit 181a by the processing of S115 by the communication unit 123a receives the reply information. Further, the time when the instruction information is sent is the time when the communication unit 123a sent to the processing unit 181a through the process of S117 sends the instruction information. The delay time TD1 is indicated by the time when the communication unit 123a sent to the processing unit 181a through the process of S115 received the reply information, and the communication unit 123a sent by the communication unit 123a through the process of S117 indicated by the communication unit 123a This is the absolute value of the difference from the time when the information was sent.

  The description of S121 to S128 is omitted because the communication unit 121a is replaced with the communication unit 122a in the description of S111 to S118 described above.

  After the processing of S118 and S128, the processing unit 181a derives the delay time difference ΔTD as the processing of S133. The delay time difference ΔTD is an absolute value of the difference between the delay time TD1 obtained by the processing unit 181a through the processing of S118 and the delay time TD2 obtained by the processing unit 181a through the processing of S128.

  Then, the processing unit 181a performs the process of S141 shown in FIG.

  Then, as the process of S141, the processing unit 181a determines whether ΔTD obtained by the processing unit 181a by the process of S133 is smaller than the threshold value VT1 set by the processing unit 181a by the process of S101.

  If the processing unit 181a determines that ΔTD is smaller than VT1 by the processing of S141, the processing unit 181a performs the processing of S142.

  On the other hand, when the processing unit 181a does not determine that ΔTD is smaller than VT1 by the processing of S141, the processing unit 181a performs the processing of S146 described later.

  When performing the process of S142, the processing unit 181a causes the communication unit 123a to send instruction information to the communication unit 121a. The instruction information is instruction information including contents for instructing the support unit 151a to change the output described in the section [Configuration and Operation].

  Then, the communication unit 123a sends instruction information to the communication unit 121a as the process of S143. The communication unit 121a sends the sent instruction information to the processing unit 182a.

  Next, the processing unit 182a sends an instruction to change the output to the output unit 131a as the processing of S144.

  Then, the output unit 131a changes the output as the process of S145.

  On the other hand, the processing unit 181a determines whether to end the processing illustrated in FIGS. 3 and 4 as processing of S147 after the processing of S142. The processing unit 181a determines whether to end the processes illustrated in FIGS. 3 and 4 based on, for example, input information from the outside.

  When the processing unit 181a determines to end the processing illustrated in FIGS. 3 and 4 by the processing of S147, the processing unit 181a ends the processing illustrated in FIGS.

On the other hand, if the processing unit 181a does not determine that the processing illustrated in FIGS. 3 and 4 is to be terminated by the processing of S147, the processing unit 181a performs the above-described processing of S111 and S121 illustrated in FIG.
[effect]
The support system of the first embodiment derives the distance value between each of the support units included in each of the pair of connectors and the control unit based on acquired information acquired by wireless communication. The support system of the first embodiment includes a distance value between one support unit and the control unit of the pair of support units, and a distance value between the other support unit and the control unit of the pair of support units. To derive the difference. The support system according to the first embodiment changes the above-described output to the worker in at least one of the pair of support units when the difference between the derived distance values satisfies a predetermined condition. Indicates. The change in the output is information regarding whether or not the pair of connectors can be connected. Therefore, the operator can easily know whether the pair of connectors can be connected by changing the output. Therefore, the support system of the first embodiment can reduce the occurrence of connector connection errors by the operator. Furthermore, the support system of the first embodiment can reduce the work amount and work time of the connection work between the connectors by the worker.
<Second embodiment>
The second embodiment is an embodiment related to a support system that supports connection between connectors by a countermeasure taken by a countermeasure section.

  FIG. 5 is a conceptual diagram illustrating a configuration of a support system 191b, which is an example of a support system according to the second embodiment. FIG. 5 illustrates a state in which the support unit 151a of the support system 191b is disposed on the connector 101a included in the device 311a illustrated in FIG. FIG. 5 shows a state in which the support unit 152a of the support system 191b is arranged on the connector 102a connected to the cable line 201a shown in FIG.

  The description of the support system 191b is the same as the description of the support system 191a shown in FIG. 1 except for the following. However, when the description of the support system 191a shown in FIG. 1 and the following description of the support system 191b are contradictory, priority will be given to the description of the next support system 191b.

  The countermeasure unit 231b is inserted between the wiring 251b and the wiring 251c between the input / output unit 241a of the device 311a and a terminal (not shown) of the connection unit 211a of the connector 101a.

  The support unit 151a includes a recording unit 111a, a communication unit 121a, an output unit 131a, and a countermeasure unit 231b.

  The processing unit 181a of the control unit 161a determines that the difference between the derived distance value between the processing unit 181a and the support unit 151a and the distance value between the processing unit 181a and the support unit 152a is a predetermined value related to the distance value. It is determined whether or not the above condition is satisfied. The condition is a condition read by the processing unit 181a from the recording unit 113a.

  When it is determined that the difference satisfies the condition, the processing unit 181a sends instruction information to the communication unit 121a of the support unit 151a via the communication unit 123a. The instruction information is instruction information for causing the countermeasure unit 231b of the support unit 151a to perform countermeasure processing described later.

  The communication unit 121a sends the instruction information received from the communication unit 123a to the processing unit 182a.

  The processing unit 182a instructs the countermeasure unit 231b to perform predetermined processing based on the instruction information sent by the communication unit 123a of the control unit 161a.

  The countermeasure unit 231b is, for example, a switch that operates according to an instruction from the processing unit 182a. The processing performed when the countermeasure unit 231b is a switch is, for example, on / off of conduction between the wiring 251b and the wiring 251c, which is performed according to an instruction from the processing unit 182a.

  Here, as the first case, for example, a case is assumed in which the connecting portion 211a and the connecting portion 212a are originally connected portions to be connected. In this case, when the distance between the support unit 151a and the support unit 152a approaches, the control unit 161a sends the instruction information to the communication unit 121a of the support unit 151a. The control unit 161a determines that the distance between the support unit 151a and the support unit 152a is close, and determines whether the difference between the distance values of the control unit 161a and the support unit 151a and the support unit 152a is smaller than a predetermined threshold. To do. At that time, the control unit 161a can derive the distance values between the control unit 161a and each of the support unit 151a and the support unit 152a by the two methods described in the first embodiment. Then, the processing unit 182a that has received the instruction information via the communication unit 121a sends an instruction based on the instruction information to the countermeasure unit 231b. The countermeasure unit 231b, which is a switch, turns on conduction between the wiring 251b and the wiring 251c that are normally turned off. The reason why the conduction between the wiring 251b and the wiring 251c is turned on is that it is safe even if the connection portion 211a and the connection portion 212a are electrically connected. On the other hand, when a connection unit (not shown) that should not be connected to the connection unit 211a approaches, the control unit 161a does not send the instruction information to the communication unit 121a. In that case, the countermeasure unit 231b keeps the conduction between the wiring 251b and the wiring 251c off.

  Or the case where the connection part 211a and the connection part 212a were the connection parts which should not be connected originally is assumed as a 2nd case. In this case, when the distance between the support unit 151a and the support unit 152a approaches, the control unit 161a sends instruction information to the communication unit 121a of the support unit 151a. Then, the processing unit 182a that has received the instruction information via the communication unit 121a sends the instruction information to the countermeasure unit 231b. Then, the countermeasure unit 231b, which is a switch, turns off conduction between the wiring 251b and the wiring 251c that are normally turned on. The reason why the conduction between the wiring 251b and the wiring 251c is turned off is that the connection portion 211a and the connection portion 212a should not be electrically connected. On the other hand, even when a connection unit (not shown) to which the connection unit 211a should be connected approaches, the control unit 161a does not send instruction information to the communication unit 121a. In that case, the countermeasure unit 231b keeps the conduction between the wiring 251b and the wiring 251c on because there is no instruction from the processing unit 182a.

  In both cases of the first case and the second case, the countermeasure unit 231b turns on the conduction between the wiring 251b and the wiring 251c when a correct connection is made between the connection units. Further, in both cases of the first case and the second case, the countermeasure unit 231b turns off the conduction between the wiring 251b and the wiring 251c when the connection unit is not correctly connected. To do. Thereby, the support system 191b can avoid energization even when the operator makes a connection error, and can suppress damage to the apparatus 311a and the apparatus (not shown) connected to the cable line 201a due to the incorrect energization.

  The countermeasure unit 231b may be a resistor or an attenuator that suppresses a current flowing between the wiring 251b and the wiring 251c according to an instruction from the processing unit 182a.

  FIG. 6 is a conceptual diagram illustrating another arrangement example of the countermeasure unit 231b.

  As shown in FIG. 6, the countermeasure unit 231b may be connected to the input / output unit 241a at a portion not in the middle of the wiring connecting the connection unit 211a and the input / output unit 241a. The countermeasure unit 231b may be a part that turns on / off power supplied from a power source (not shown) to the input / output unit 241a.

  The countermeasure unit 231b illustrated in FIG. 5 is an example of a countermeasure unit installed inside the device 311a outside the connector 101a. However, the installation location of the countermeasure unit is not particularly limited. The countermeasure unit may be installed inside the connector 101a, for example. Alternatively, the countermeasure unit may be installed outside the device 311a.

As described above, the support system 191b illustrated in FIG. 5 suppresses the occurrence of a risky problem caused by the countermeasure unit 231b when an incorrect connector is connected by an operator. . The suppression is performed when the operator connects the wrong connectors despite the output change by the output unit 131a. The countermeasure unit 231b performs the suppression by, for example, blocking the electrical connection between the connection unit 211a and the input / output unit 241a or turning off the power supply of the input / output unit 241a as described above. For this reason, the support system 191b can suppress the occurrence of a problem that may be caused by the erroneous connection when the erroneous connection between the connectors is performed by the operator even if the output of the output unit is output.
[Processing flow]
The processing example of the processing performed by the support system 191b shown in FIG. 5 is the same as the processing shown in FIGS. 3 and 4 except that FIG. 4 is replaced by FIG. However, in the process shown in FIG. 3 and the description thereof, the above-described reading described in the description of FIG. 5 is performed.

  FIG. 7 is a conceptual diagram (part replacing FIG. 4) showing an example of processing performed by the support system 191b.

  Description of processes other than the processes of S144-2 and S145-2 in the process illustrated in FIG. 7 is the same as the description of the process illustrated in FIG.

  After the process of S143, before and after the process of S144, the processing unit 182a sends instruction information indicating an instruction to take a countermeasure to the countermeasure unit 231b as the process of S144-2.

Then, the countermeasure unit 231b performs the countermeasure described in the section [Configuration and Operation] as the process of S145-2.
[effect]
Since the support system of the second embodiment includes the configuration of the support system of the first embodiment, first, the same effect as the support system of the first embodiment is achieved.

In addition to the above, in the support system according to the second embodiment, when an incorrect connector is connected by an operator even if there is an output from the output unit, there is a problem that may be caused by the erroneous connection. Can be suppressed.
<Third embodiment>
The third embodiment is an embodiment relating to a support system that can support the work of connecting the connector groups included in the two devices with a cable group.
[Configuration and operation]
FIG. 8 is a conceptual diagram illustrating a configuration of a support system 191b that is a first example of the support system according to the third embodiment.

  The support system 191b includes support unit groups 15a, 15b, 15c, and 15d, and a control unit 161a.

  The support unit group 15a includes n support units of the support unit 1511 to the support unit 151n. A point 291a illustrated in FIG. 8 indicates that a support unit (not illustrated) may exist between the support unit 1512 and the support unit 151n. And each support part with which the support part group 15a is provided is each provided with the connector with which the apparatus 311b is provided. In FIG. 8, a dotted rectangle outside one solid line rectangle representing the support unit included in the support unit group 15a represents a connector included in the device 311b.

  The support unit group 15b includes n support units from the support unit 1521 to the support unit 152n. A point 291b shown in FIG. 8 indicates that a support unit (not shown) may exist between the support unit 1522 and the support unit 152n. Each support unit included in the support unit group 15b is installed in a connector provided on one side of the cable group 271a (the left side of the cloud-shaped figure 281a illustrated in FIG. 8). In FIG. 8, one dotted rectangle outside the solid rectangle representing the support unit included in the support unit group 15b represents a connector provided on one side of the cable group 271a (the left side of the cloud-shaped figure 281a shown in FIG. 8). .

  The support unit group 15c includes n support units from the support unit 1531 to the support unit 153n. A point 291c illustrated in FIG. 8 indicates that a support unit (not illustrated) may exist between the support unit 1532 and the support unit 153n. And each support part with which the support part group 15c is provided is each provided with the connector with which the other side (right side of the cloud-shaped figure 281a shown in FIG. 8) of the cable group 271a is provided. In FIG. 8, one dotted rectangle outside the solid rectangle representing the support unit included in the support unit group 15 c represents a connector provided on the other side of the cable group 271 a (on the right side of the cloud-shaped figure 281 a illustrated in FIG. 8). .

  The support unit group 15d includes n support units from the support unit 1541 to the support unit 154n. A point 291d illustrated in FIG. 8 indicates that a support unit (not illustrated) may exist between the support unit 1542 and the support unit 154n. Each support unit included in the support unit group 15d is provided in a connector included in the device 311c. In FIG. 8, a dotted rectangle outside one solid line rectangle representing the support unit included in the support unit group 15d represents a connector included in the device 311c.

  And it is assumed that the connector provided with one support part of the support part group 15a should be actually connected to the connector provided with one support part of the support part group 15b.

  Further, it is assumed that a connector including one support unit of the support unit group 15c should be actually connected to a connector including one support unit of the support unit group 15d.

  A terminal (not shown) of one connector provided with each support part provided in the support part group 15b and a terminal (not shown) of one connector provided with each support part provided in the support part group 15b constitute one cable line group 261a. Connected by cable. However, which connector terminal includes one support unit that configures the support unit group 15b and which connector terminal includes one support unit that configures the support unit group 15c is connected by a cable. It is assumed that it may be difficult to discriminate depending on the person's visual observation. The cloud-shaped figure 281a represents that it may be difficult to discriminate depending on the visual observation of the operator.

  The configuration and description of each support unit included in the support unit group 15a and the support unit group 15d are the same as the configuration and description of the support unit 151a illustrated in FIG.

  The configuration and description of each support unit included in the support unit group 15b and the support unit group 15c are the same as the configuration and description of the support unit 152a illustrated in FIG.

  In the recording unit 113a of the control unit 161a, connection relationship information and distance value difference information described below are recorded in advance.

  The connection relationship information is information representing the correspondence relationship of the support units included in the pair of connectors for each pair of connectors to be actually connected.

  The connection relation information is information as shown in FIG. 9, for example. FIG. 9A shows the correspondence between the identification information of the support unit of the support unit group 15a and the identification information of the support unit of the support unit group 15b. FIG. 9B shows the correspondence between the identification information of the support unit of the support unit group 15d and the identification information of the support unit of the support unit group 15c.

  In FIG. 9A, the support unit whose identification information of the support unit group 15 a is 1511 is associated with the support unit whose identification information of the support unit group 15 b is 1525. This means that the connector including the support unit whose identification information of the support unit group 15a is 1511 should be actually connected to the connector including the support unit whose identification information of the support unit group 15b is 1525. The same applies to the other identification information shown in FIG.

  The distance value difference information is information including a condition of a difference between the distance value between the control unit 161a and a certain support unit illustrated in FIG. 8 and the distance value between the control unit 161a and another support unit.

  FIG. 10 illustrates an example of distance value difference information that represents a difference condition between distance values for a combination of identification information of the support unit of the support unit group 15a and identification information of the support unit of the support unit group 15b.

Since each of the support unit group 15a and the support unit group 15b includes n support units, there are n ^two combinations of the support unit identification information of the support unit group 15a and the support unit identification information of the support unit group 15b. . FIG. 10 shows an example of the condition for the difference between the distance values for the n ^two combinations. In the distance value difference information illustrated in FIG. 10, the combination of the identification information of the support unit of the support unit group 15 a and the identification information of the support unit of the support unit group 15 b indicates that the difference condition between the distance values is “ “Smaller than Y” is set. That is, the combinations are 1511 and 1525, 1512 and 1527, 1513 and 1527, and 151n and 1523. In the distance value difference information shown in FIG. 10, if the combination of the identification information of the support unit of the support unit group 15a and the identification information of the support unit of the support unit group 15b is other than the above, the difference between the distance values is different. Is set to “not smaller than X”.

  When only the combination information whose distance value difference condition is “smaller than Y” is used for the processing performed by the support system 191b, only the combination information “smaller than Y” may be set as the distance value difference information. I do not care.

  Hereinafter, a case where the output unit (the output unit 131a illustrated in FIG. 5) of the support unit included in the support unit group 15a is an LED will be described as an example. Moreover, below, the case where the connector provided with the assistance part of the assistance part group 15a and the connector provided with the assistance part of the assistance part group 15b are performed is demonstrated.

  The processing unit 181a selects the identification information of the pair of support units in the connection relation information from the recording unit 113a. The pair of support units of the pair of identification information selected by the processing unit 181a is hereinafter referred to as “selected pair”. And the process part 181a selects the identification information of the assistance part which belongs to the assistance part group 15a among the pair of identification information. Hereinafter, the support unit selected by the processing unit 181a is referred to as a “selected support unit”. Then, the processing unit 181a causes the communication unit 123a to send instruction information including an instruction to light the LED to the selected support unit. Instruction information including an instruction to light the LED is sent to the selected support part to the communication part 123a. Then, the selected support unit receives the instruction information and turns on the LED.

  The processing unit 181a sends the reply information to the respective support units of the selected pair via the communication unit 123a, and sends instruction information for sending the reply information to the communication unit 123a. The reply information is sent to the unit 123a.

  The communication unit 123a acquires the acquisition information based on the return information received from each support unit of the selected pair. Then, the processing unit 181a derives a distance value between each support unit of the selected pair and the communication unit 123a from the acquired information. Then, the processing unit 181a derives a difference between distance values between the communication unit 123a and each support unit.

  The processing unit 181a reads distance value difference information from the recording unit 113a. Then, the processing unit 181a selects a difference condition between the distance values set for the selected pair from the distance value difference information. Then, the processing unit 181a determines whether the difference between the derived distance values satisfies the condition for the difference between the distance values set for the selected pair. Below, the case where the condition of the difference between the distance values set for the selected pair is smaller than the value Y will be described. Further, the countermeasure unit (the countermeasure unit 231b shown in FIG. 5) of each support unit of the support unit group 15a is a switch, and is normally turned off, but is turned on when the connectors to be actually connected are connected. Suppose you want to.

  Hereinafter, a connector including a selected support unit is referred to as a “selected connector”.

  Now, the operator recognizes the lighting of the LED of the selected support unit, and tries to connect the selected connector and the connector including the support unit of the support unit group 15b. Connectors are usually written with numbers and symbols. The worker has in advance contrast information that is information indicating which number or symbol of the connectors should be connected to each other. The operator tries to connect the connectors based on the comparison information. When there is no error in the connection between the connectors, the support units of the selected pair come closer to each other. When the support units of the selected pair approach each other to some extent, the difference between the distance values between the communication unit 123a of the control unit 161a and each of the two support units of the selected pair becomes smaller than the value Y.

  Then, the processing unit 181a of the control unit 161a determines that the difference between the derived distance values satisfies the condition for the difference between the distance values set for the selected pair.

  Then, the processing unit 181a causes the selected support unit to turn off the LED of the selected support unit and to send instruction information for enabling conduction to the communication unit 123a. The conduction is conduction between the terminal of the selected connector and the input / output unit (input / output unit 241a shown in FIG. 5) of the device 311a.

  The communication unit 123a transmits instruction information for turning off the LED of the selected support unit and enabling conduction to the selected support unit.

  The selected support unit turns off the LED and enables the conduction.

  The operator visually confirms that the LED is turned off and confirms that the connection with the connector having the turned-off LED is correct. And an operator connects the connector which is going to connect with the connector provided with the LED which turned off. In the connected state, the LED related to the selected connector is turned off, and the conduction is possible.

  Assume that the worker brings a connector that does not include the support unit for the selected pair close to the selected connector. In that case, the processing unit 181a of the control unit 161a does not determine that the difference between the derived distance values satisfies the condition for the difference between the distance values set for the selected pair. Therefore, even if the operator brings a connector that does not include the support unit for the selected pair close to the selected connector, the LED is not turned off. Furthermore, even if an operator connects a connector that does not include the support unit for the selected pair to the selected connector even though the LED is not turned off, the conduction is not possible.

  The operation of the support system 191b when the worker connects the connector including the support unit of the support unit group 15d and the connector including the support unit of the support unit group 15c is the same as described above.

  The support system 191b and the worker repeatedly perform the above operation and work until the connection between all the target connectors is completed.

  Note that a connector that can ensure that the probability of an error in connection between connectors can be ignored without using the support system 191b does not necessarily include the support unit of the support system 191b. A case where it can be ensured that the probability of an error in connection between connectors can be ignored is, for example, a case where the arrangement of a plurality of connectors is fixed in advance.

  The controller 161a may be divided into two parts capable of communicating with each other.

  FIG. 11 is a conceptual diagram illustrating a configuration of a support system 191c that is a second example of the support system according to the third embodiment.

  The support system 191c includes support unit groups 15a, 15b, 15c and 15d, and a control unit 161a.

  The description of the support unit groups 15a, 15b, 15c, and 15d is the same as the description of the support unit groups 15a, 15b, 15c, and 15d shown in FIG.

  The controller 161a includes a first part 351a and a second part 352a.

  The first part 351a is relatively close to the support unit groups 15a, 15b, 15c, and 15d, and is the control unit 161a that is supposed to communicate with each support unit of the support unit groups 15a, 15b, 15c, and 15d. Part. The first part 351a obtains information for deriving a distance value between the first part 351a and each support unit by communicating with each support unit of the support unit groups 15a, 15b, 15c, and 15d.

  The second part 352a receives information obtained by the first part 351a for obtaining a distance value between the first part 351a and each support part by communication with the first part 351a. Then, the second part 352a performs derivation of the distance value between the first part 351a and each support part.

  Hereinafter, the details of the control unit 161a illustrated in FIG. 11 will be described.

  The first part 351a includes a communication unit 123aa, a processing unit 181aa, and a recording unit 113aa.

  The second unit 352a includes a communication unit 123ab, a processing unit 181ab, and a recording unit 113ab.

  The processing unit 181ab and the processing unit 181ac are portions corresponding to the processing unit 181a illustrated in FIG. In addition, the recording unit 113aa and the recording unit 113ab are portions corresponding to the recording unit 113a illustrated in FIG. In addition, the communication unit 123aa and the communication unit 123ab are portions corresponding to the communication unit 123a illustrated in FIG. The description of the processing unit 181a, the recording unit 113a, and the communication unit 123a illustrated in FIG. 11 is the same as the description of the processing unit 181a, the recording unit 113a, and the communication unit 123a illustrated in FIG.

  The communication unit 123aa communicates with each support unit of the support unit groups 15a, 15b, 15c, and 15d. And communication part 123aa acquires the acquisition information for deriving the distance value of communication part 123aa and each support part by communicating with each support part.

  The acquired information is, for example, the delay time described in the first method for measuring the distance value according to the first embodiment. The delay time is a delay time when the communication unit 123aa communicates with the support unit.

  Or acquisition information is field intensity explained in the 2nd method of measuring distance value of a first embodiment, for example. The radio wave intensity is the radio wave reception intensity sent from the support unit to the communication unit 123aa.

  The communication unit 123aa sends the acquired information to the processing unit 181aa.

  Further, the communication unit 123aa sends information instructed by the processing unit 181aa to each support unit.

  In addition, the communication unit 123aa sends information instructed by the processing unit 181aa to the communication unit 123ab of the second unit 352a.

  The processing unit 181aa uses the acquired information received from the communication unit 123aa as transmission information for sending to the communication unit 123ab of the second unit 352a. The processing unit 181aa causes the communication unit 123aa to send the transmission information to the communication unit 123ab.

  Further, the processing unit causes the communication unit 123aa to send the instructed information to each support unit according to the instruction information that the communication unit 123ab of the second unit 352a sends to the communication unit 123aa.

  The processing unit 181aa also causes the recording unit 113aa to record the acquired information received from the communication unit 123aa and the information processed by the processing unit 181aa as necessary.

  The recording unit 113aa records information instructed by the processing unit 181aa. The recording unit 113aa also sends information recorded by the recording unit 113aa instructed by the processing unit 181aa to the processing unit 181aa.

  The communication unit 123ab of the second part 352a communicates with the communication unit 123aa of the first part 351a. Then, the communication unit 123ab sends information received from the communication unit 123aa of the first part 351a by communication to the processing unit 181ab. The communication unit 123ab also sends information instructed by the processing unit 181ab to the communication unit 123aa by wireless communication.

  The recording unit 113ab records connection relation information and distance value difference information in advance. The description of the connection relation information and the distance value difference information is as described with reference to FIG. 8, FIG. 9, and FIG. Then, the recording unit 113ab sends information instructed by the processing unit 181ab to the processing unit 181ab. The recording unit 113ab also records information instructed by the processing unit 181ab.

  The processing unit 181ab causes the recording unit 113ab to record the acquisition information received by the processing unit 181aa of the first part 351a through the communication unit 123aa and the communication unit 123ab. Then, the processing unit 181ab identifies the selected pair in the connection relation information read from the recording unit 113ab. Then, the processing unit 181ab sends instruction information including an instruction to light the LED to the selected support unit via the communication unit 123ab and the communication unit 123aa. Then, the selected support unit turns on the LED.

  The processing unit 181a reads distance value difference information from the recording unit 113a. Then, the processing unit 181a selects a difference condition between the distance values set for the selected pair from the distance value difference information. Then, the processing unit 181a determines whether the difference between the derived distance values satisfies the condition for the difference between the distance values set for the selected pair.

  Now, it is assumed that the worker recognizes the lighting of the LED of the selected support unit, and tries to connect the selected connector and the connector including the support unit of the support unit group 15b. Connectors are usually written with numbers and symbols. The worker has in advance contrast information that is information indicating which number or symbol of the connectors should be connected to each other.

  The operator tries to connect the connectors based on the comparison information. When there is no error in the connection between the connectors, the support units of the selected pair come closer to each other. When the support units of the selected pair approach each other to some extent, the difference between the distance values between the communication unit 123aa of the first part 351a and each of the two support units of the selected pair becomes smaller than the value Y.

  Then, the processing unit 181ab of the second part 352a determines that the difference between the derived distance values satisfies the condition for the difference between the distance values set for the selected pair.

  Then, the processing unit 181ab causes the communication unit 123ab to send instruction information for turning off the LED of the selected support unit and enabling conduction to the selected support unit through the communication unit 123aa. The conduction is conduction between the terminal of the selected connector and the input / output unit (input / output unit 241a shown in FIG. 5) of the device 311b.

  The selected support unit turns off the LED and enables the conduction.

  The operator visually confirms that the LED is turned off and confirms that the connection with the connector having the turned-off LED is correct. And an operator connects the connector which is going to connect with the connector provided with the LED which turned off. In the connected state, the LED related to the selected connector is turned off, and the conduction is possible.

  Assume that the worker brings a connector that does not include the support unit for the selected pair close to the selected connector. In that case, the processing unit 181aa of the second part 352a does not determine that the difference between the derived distance values satisfies the condition for the difference between the distance values set for the selected pair. Therefore, even if the operator brings a connector that does not include the support unit for the selected pair close to the selected connector, the LED is not turned off. Furthermore, even if an operator connects a connector that does not include the support unit for the selected pair to the selected connector even though the LED is not turned off, the conduction is not possible.

  In the description of the control unit 161a shown in FIG. 11 above, the communication unit 123aa communicates with each support unit in the following two types. The first communication is communication performed to acquire information for deriving a distance value between the communication unit 123aa and each support unit. The second communication is communication in which the processing unit 181ab of the second part 352a sends instruction information for each support unit to the first support unit 351a via the communication unit 123ab.

  Of the two types of communication, the first communication is performed by the first part 351a. In order to acquire the acquired information, it is better that the communication unit that performs communication for acquiring the acquired information is close to each support unit. This is because, when the communication unit is near each support unit, the communication unit can acquire acquisition information that can accurately derive the distance value between the communication unit and each support unit. When the communication unit is near each support unit, the distance value between the communication unit and each support unit can be derived with high accuracy mainly when the communication unit is near each support unit. This is because the influence of reflection of radio waves from other objects can be reduced. The purpose of including the first part 351a in the control unit 161a illustrated in FIG. 11 is to allow the distance value between the communication unit and each support unit to be derived with high accuracy.

On the other hand, of the two types of communication, the second communication is not necessarily performed via the communication unit 123aa of the first part 351a. Accordingly, the second unit 352a may directly perform communication corresponding to the second communication with each support unit without using the first part 351a. The second communication is sending instruction information other than the instruction information sent by the first part to each support unit. When the second unit 352a performs communication corresponding to the second communication directly with each support unit without passing through the first part 351a, the communication unit 123ab performs communication corresponding to the second communication directly with each support unit. .

  And the communication part 123a sends the acquisition information acquired by the process of S215 to the process part 181a as a process of S216.

  Next, as the process of S217, the processing unit 181a derives a distance value with each support unit of the selected pair from the acquired information received by the communication unit 123a by the process of S216.

  Then, the processing unit 181a derives the difference between the distance values between the communication unit 123a and each support unit of the selected pair as the processing of S218.

  Next, the processing unit 181a reads distance value difference information from the recording unit 113a as the process of S219.

  And the process part 181a selects the conditions of the difference of the distance values set about the selected pair from distance value difference information as a process of S220.

  Next, the processing unit 181a performs the process of S231 illustrated in FIG.

  When performing the processing of S231, the processing unit 181a determines whether the difference between the derived distance values satisfies the condition of the difference between the distance values set for the selected pair.

  When the processing unit 181a determines that the difference between the derived distance values satisfies the condition of the difference between the distance values set for the selected pair by the processing of S231, the processing unit 181a performs the processing of S232.

  On the other hand, if the processing unit 181a does not determine that the difference between the derived distance values satisfies the condition of the difference between the distance values set for the selected pair by the processing of S231, the processing of S212 is performed. Do.

  The support system 191b performs the process of S202 described above and the process of S234 after the process of S232.
