Embodiment 1. FIG.
FIG. 1 is a diagram illustrating an overall configuration example of an information processing system 1 according to the first embodiment to which the present disclosure is applied. As shown in FIG. 1, the information processing system 1 performs a mapping process in which an apparatus such as the image forming apparatus 5 and an external terminal 7 communicate with each other and map the position of the apparatus to a floor map. . The mapping process is controlled by one or more processors, and the one or more processors execute one or more modules stored in the memory. In the information processing system 1, a client PC 2, a server 3, an image forming apparatus 5, and an external terminal 7 can communicate with each other via a network 11. The client PC 2 is a general personal computer and is controlled by an operating system. The client PC 2 can execute the mapping process in cooperation with the server 3 by installing one or more modules that execute the mapping process. Note that it is preferable that one or more modules that execute the mapping process are also installed in the server 3.

  FIG. 2 is a block diagram illustrating a configuration example of the image forming apparatus 5 according to the first embodiment. The image forming apparatus 5 receives a print job output from the client PC 2 via the network 11 and performs print processing according to the print setting of the print job. The image forming apparatus 5 may perform only a printing function, or may be an MFP (Multi-Functional Peripheral) capable of performing a copying function and the like. The image forming apparatus 5 has a function for realizing printing and a function for transmitting a beacon signal. The controller 51, the storage unit 52, the print output unit 53, the communication unit 54, the beacon transmission unit 55, And an operation unit 56 and the like, and perform various functions by operating them in combination.

  The controller 51 is built in the image forming apparatus 5 and is a control device that controls the image forming apparatus 5 in an integrated manner. The controller 51 includes one or more processors, and specifically includes a CPU, an I / O interface, and various semiconductor memories such as a RAM and a ROM. The controller 51 executes various processes when the CPU executes various kinds of software including one or more modules stored in the ROM. Various software may be installed in the image forming apparatus 5 via a portable recording medium such as a USB memory or the network 11. Specifically, the controller 51 performs various functions including a communication control unit 511, a beacon control unit 512, and an operation control unit 513 by executing various modules. The communication control unit 511 controls communication operations with various devices such as the external terminal 7 or the client PC 2 by cooperating with the communication unit 54. The beacon control unit 512 controls the beacon signal including the packet information and the transmission interval of the beacon signal by cooperating with the beacon transmission unit 55. The operation control unit 513 controls various operations such as a print output operation performed by the image forming apparatus 5.

  The print output unit 53 prints out an image on various media such as paper based on the print job. The communication unit 54 is an interface for receiving a print job from various devices such as the external terminal 7 or the client PC 2 through network communication using TCP / IP. For example, the image forming apparatus 5 can transmit and receive various types of information to and from the external terminal 7, the client PC 2, the server 3, and the like via the communication unit 54.

  The beacon transmission unit 55 can transmit a beacon signal by wireless communication. The beacon transmission unit 55 transmits a beacon signal of a radio wave having a preset output. The beacon signal is based on, for example, NFC (Near Field Communication), Bluetooth (registered trademark), Bluetooth Low Energy, Bluetooth Smart (registered trademark), or iBeacon (registered trademark). Note that the beacon signal may conform to ZigBee (registered trademark). Specifically, the beacon transmission unit 55 repeatedly transmits a beacon signal at a constant transmission interval. The beacon signal includes, for example, unique device identification information that can uniquely identify a device such as the image forming device 5. Therefore, when a plurality of devices such as the image forming device 5 are arranged, device identification information is assigned to each device, and since such device identification information is included in the beacon signal, the device identification information included in the beacon signal is By extracting, it is possible to identify the device that is the source of the beacon signal.

  That is, the one or more modules further include an extraction instruction and a transmission source identification instruction. The extraction instruction is for extracting device identification information included in the beacon signal. The transmission source specifying instruction is for specifying a device that is a transmission source of a beacon signal based on the device identification information extracted by the extraction instruction. The device identification information includes MIB information. Therefore, the extraction instruction only needs to extract MIB information. The transmission source specifying instruction specifies a device that is a transmission destination of a beacon signal based on the MIB information extracted by the extraction instruction.

  Since the beacon signal transmitted from the beacon transmission unit 55 propagates in the air while being gradually attenuated, the radio wave intensity of the beacon signal becomes stronger as the distance from the apparatus such as the image forming apparatus 5 becomes shorter, and image formation is performed. There is a tendency that a position far from the device such as the device 5 becomes weaker. That is, the beacon signal is a wireless signal that can be wirelessly received within a certain distance. Therefore, it can be said that a device that can receive a beacon signal exists within a certain distance from the source of the beacon signal. Note that the transmission source specifying instruction may specify a device that is a transmission source of a beacon signal existing on the same floor as the external terminal 7 based on the signal strength of the beacon signal.

  The storage unit 52 is a memory such as a hard disk drive or a semiconductor memory, and can store MIB (Management Information Base) information. The operation unit 56 includes an operation input unit 561 and a display unit 562. The operation input unit 561 receives various operations of the image forming apparatus 5.

  FIG. 3 is a block diagram illustrating a configuration example of the external terminal 7 according to the first embodiment. In FIG. 3, a smartphone is illustrated as an example of the external terminal 7, but it may be a tablet terminal, a wristwatch with a wireless function, a digital camera equipped with FlashAir (registered trademark), or the like. The external terminal 7 is a device that can perform a function of receiving a beacon signal transmitted from the image forming apparatus 5. If the external terminal 7 is a device compatible with Bluetooth Low Energy (Bluetooth 4.0), the external terminal 7 can receive even if the beacon signal is iBeacon (registered trademark).

The controller 71 includes one or more processors, and specifically includes a CPU, an I / O interface, and various semiconductor memories such as a RAM and a ROM. The controller 71 executes various processes when the CPU executes various kinds of software including one or more modules stored in the ROM. Various software may be installed in the external terminal 7 via a portable recording medium such as a USB memory or the network 11. Specifically, the controller 71 performs various functions including a communication control unit 711, a time information acquisition unit 712, and a terminal identification information acquisition unit 713 by executing various modules. The communication control unit 711 controls communication operations with the image forming apparatus 5, the client PC 2, the server 3, and the like by cooperating with the communication unit 73. The time information acquisition unit 712 acquires time information. For example, the time information acquisition unit 712 can acquire time information when receiving a beacon signal. The time information acquisition unit 712 not only acquires time information from a clock unit (not shown), but also acquires time information from a radio wave including a time that is a national reference such as a standard radio wave transmitted from a long wave standard frequency station or the like. You may get it. Further, the time information acquisition unit 712 may acquire GPS time as time information using a GPS sensor 774 described later.

  The terminal identification information acquisition unit 713 acquires unique terminal identification information that can uniquely identify the external terminal 7. Such terminal identification information is assigned to each external terminal 7. Therefore, when there are a plurality of external terminals 7, terminal identification information is assigned to each, and such terminal identification information is held in the external terminal 7. Among the terminals 7, it is possible to specify the external terminal 7 that is the transmission destination of the beacon signal. The one or more modules further include a transmission destination specifying instruction. The transmission destination specifying instruction is for specifying the external terminal 7 that is the transmission destination of the beacon signal based on the terminal identification information.

  The position information detection unit 77 performs a function of detecting the position information of the external terminal 7, that is, the position information of the own device. The position information detection unit 77 includes at least one of an acceleration sensor 771, a gyro sensor 772, and a magnetic direction sensor 773, and a GPS sensor 774. The position information detection unit 77 detects the position information of the own device by the GPS sensor 774 in an outdoor environment where GPS can be received. In an indoor environment where GPS cannot be received, the position information detection unit 77 uses at least one of various sensors such as an acceleration sensor 771, a gyro sensor 772, and a magnetic orientation sensor 773 to detect the position of the own device. Estimate information. When estimating the position information of the own aircraft using various sensors, the detailed description is omitted, but the gain error of each sensor is estimated by a Kalman filter, as is done in a car navigation system or the like. That's fine.

  The communication unit 73 can perform wireless communication using a plurality of different communication methods. The communication unit 73 includes a beacon receiving unit 731, a beacon acquisition time information communication unit 732, and a device movement information communication unit 733. The beacon receiving unit 731 performs a function of receiving a beacon signal transmitted from an apparatus such as the image forming apparatus 5. The beacon acquisition time information communication unit 732 performs a function of transmitting / receiving various data to / from the image forming apparatus 5 or the server 3. When a beacon signal is received by the beacon receiving unit 731, the beacon acquisition time information communication unit 732 detects the position information of the own device detected by the position information detection unit 77, packet information of an apparatus such as the image forming apparatus 5, and an image Information on the distance between the apparatus such as the forming apparatus 5 and the external terminal 7, time information when receiving the beacon signal, terminal identification information, and the like are transmitted to the server 3. The packet information of an apparatus such as the image forming apparatus 5 includes apparatus identification information, specifically, an IP address and MIB information. The distance information between the apparatus such as the image forming apparatus 5 and the external terminal 7 may be obtained by conversion from the radio wave intensity of the beacon signal.

  That is, the external terminal 7 transmits server transmission information such as device identification information, signal strength, position information of its own device, time information, and terminal identification information to the server 3. When it is determined that there is a change in the position of an apparatus such as the image forming apparatus 5, that is, when an apparatus such as the image forming apparatus 5 has moved, the apparatus movement information communication unit 733 notifies the server 3 to that effect. It performs the function to perform.

  The storage unit 72 is a memory such as a hard disk drive or a semiconductor memory, and stores server transmission information and device movement notification information. As described above, the server transmission information is device identification information, signal strength, position information of the own device, time information, and terminal identification information, and is sequentially accumulated as a history of time information at the time of reception. Is. The device movement notification information is information received from the server 3 and stores a reception confirmation period corresponding to the importance. Although the details will be described later, the importance is an index that the external terminal 7 that has received the beacon signal from the apparatus such as the image forming apparatus 5 most frequently is most important.

  That is, the presence / absence of a change in the position of the apparatus such as the image forming apparatus 5 is determined by comparing the reception confirmation period according to the reception frequency of the beacon signal and the period when the external terminal 7 does not receive the beacon signal. To do. The external terminal movement detection unit 78 obtains the position information of the external terminal 7 when the beacon signal of the apparatus such as the image forming apparatus 5 has been received in the past and the current position information of the external terminal 7. It is to detect whether or not they are different. Therefore, the external terminal movement detection unit 78 detects whether or not the external terminal 7 itself has moved.

  Specifically, the one or more modules include a determination instruction and a reflection instruction. When the beacon signal is received by the communication unit 73, the determination instruction is based on the position information of the external terminal 7 detected by the position information detection unit 77 and the time information acquired by the time information acquisition unit 712. This is for determining whether or not the position of the apparatus such as the image forming apparatus 5 has changed. More specifically, when the external terminal 7 does not receive a beacon signal from a device such as the image forming apparatus 5 exceeds the reception confirmation period corresponding to the importance calculated by the calculation instruction, It is determined that there is a change in position. However, if the current position information of the external terminal 7 is the same as when the beacon signal was received in the past, the determination instruction determines whether the period during which the beacon signal is not received exceeds the reception confirmation period. Is. The reflection instruction is for reflecting the change in the position of the apparatus on the floor map when it is determined that there is such a change in the position of the apparatus according to the determination instruction. Details of the floor map will be described later.

  The operation unit 76 includes an operation input unit 761 and a display unit 762. The operation input unit 761 receives various operations of the external terminal 7.

  The controller 31 is built in the server 3 and is a control device that comprehensively controls the server 3. The controller 31 includes one or more processors, and specifically includes a CPU, an I / O interface, and various semiconductor memories such as a RAM and a ROM. The controller 31 performs various processes when the CPU executes various software including one or more modules stored in the ROM.

  Various software may be installed in the server 3 via a portable recording medium such as a USB memory or the network 11. Specifically, the controller 31 performs various functions including the communication control unit 311 and the position information calculation unit 312 by executing various modules.

Existing. The external terminal (1) exists in the (F) row (2) column of the floor map, and the external terminal (2) exists in the (A) row (4) column of the floor map. Therefore, it is assumed that the user who owns the external terminal (1) has a seat at the position of the (F) row (2) column of the floor map and can always receive a beacon signal. On the other hand, it is assumed that the user who owns the external terminal (2) has a seat at the position of the (A) row (4) column of the floor map and cannot receive the beacon signal. Therefore, it is assumed that the external terminal (2) can receive the beacon signal when the user who owns the external terminal (2) passes near the printer (A). Note that the time and interval for transmitting the beacon signal can be freely set by the printer (A). For example, it can be scheduled so that it is transmitted at intervals of 10 minutes only during business hours from 9:00 to 17:00.

In step S12, the position information of the own device is detected. In step S13, time information is acquired. In step S14, it is determined whether there is a change in the position of the apparatus based on the position information of the own device and the time information. If it is determined that there is a change in the position of the device based on the position information of the own device and the time information (step S14; Y), the process proceeds to step S15. On the other hand, when it is determined that there is no change in the position of the apparatus based on the position information of the own device and the time information (step S14; N), the process of updating the map information of the floor map is ended. In step S15, after the change in the position of the apparatus is reflected in the floor map, the process of updating the map information of the floor map ends.

In step S52, a device serving as a transmission source of a beacon signal among a plurality of devices is identified based on the MIB information, and the process of identifying a device based on MIB information ends in an environment where a plurality of devices exist. Specifically, information related to a device included in the MIB information is identified by OID using SNMP. For example, the OID for acquiring the system name of the device is iso. org. dod. internet. mgmt. mib-2. system. It becomes sysName. That is, since the OID of the MIB information is sent to the external terminal 7 as the device identification information included in the beacon signal, if the OID of the MIB information is extracted on the external terminal 7 side, the device that is the transmission destination of the beacon signal is selected. Can be identified.

Note that the processing in steps S72 to S75 may be any of sequential execution, parallel execution in the same device, and parallel execution in different devices. That is, the processes of steps S72 to S75 are out of order as long as they are completed before the process of step S76.

  In step S71, it is determined whether a beacon signal is received. When it determines with having received the beacon signal (step S71; Y), a process transfers to step S72. On the other hand, when it determines with not receiving a beacon signal (step S71; N), the process of step S71 will be in a standby state as it is.

  FIG. 13 is a diagram illustrating an example of a part of the external terminal transmission information in the data table held by the server 3 according to the first embodiment. An example of FIG. 13 shows a part of server transmission information stored in the server 3 as external terminal transmission information. The beacon signal of the printer (A) is sent to the external terminal (1) 19 times at a sending interval of 10 minutes between 9:00 and 12:00, and the external terminal (1) sends all the beacon signals. Can be received. On the other hand, the external terminal (2) can receive the beacon signal only once at 10:10. The position information of the external terminals (1) and (2) at the time of receiving the beacon is (F) column (2) row of the floor map. Therefore, (F) column (2) row is stored as apparatus position information as position information of the printer (A).

  FIG. 14 is a diagram illustrating an example of a floor map displayed on the external terminal 7 according to the first embodiment and associated with the position of the apparatus. When the server 3 receives a request for the apparatus position information of the image forming apparatus 5 from the external terminal 7, the server 3 stores the floor map stored as the map information and the printer (A) called (F) column (2) row of the floor map. The device position information is transmitted to the external terminal 7. The external terminal 7 can display a floor map as shown in FIG. 14 by superimposing the position of the printer (A) on the floor map acquired from the server 3.

FIG. 18 is a diagram illustrating an example of items of importance and reception confirmation period of the external terminal 7 in the data table held by the server 3 according to the first embodiment. FIG. 19 is a flowchart illustrating an example of processing for setting a reception confirmation period of the external terminal 7 according to the first embodiment.

  The processing of steps S91 to S95 calculates the reception success rate of each external terminal 7 beacon signal based on the number of times the beacon signal is transmitted from the image forming apparatus 5 and the number of times the beacon signal is received by the external terminal 7. The calculation result is used as the importance of the external terminal 7. A reception confirmation period shown in FIG. 18 is set as a time until the server 3 is notified of a change in the position of the image forming apparatus 5 in accordance with the importance. Note that the processing in step S91 and the processing in step S92 may be any of sequential execution, parallel execution in the same device, and parallel execution in different devices. That is, the processes in steps S91 and S92 are out of order as long as they are completed before the process in step S93. Further, as a pre-process for starting the process of step S91, for example, external terminal transmission information stored in the storage unit 32 of the server 3 is acquired, but server transmission information stored in the storage unit 72 of the external terminal 7 is acquired. It may be done.

  In step S91, the number of beacon signals transmitted from the apparatus to the external terminal 7 is acquired. In step S92, the number of times a beacon signal is received by the external terminal 7 from the apparatus is acquired. In step S93, the importance level of the external terminal 7 is obtained based on the number of beacon signals transmitted from the apparatus to the external terminal 7 and the number of beacon signals received by the external terminal 7 from the apparatus. In step S94, it is determined whether there is another external terminal 7 specified by the terminal identification information. If it is determined that there is another external terminal 7 specified by the terminal identification information (step S94; Y), the process returns to step S91, and the processes of steps S91 to S93 are repeated. On the other hand, when it is determined that there is no other external terminal 7 specified by the terminal identification information (step S94; N), the process proceeds to step S95. In step S95, the calculated importance of the external terminal 7 is notified to the corresponding external terminal 7, and the process of calculating the importance of the external terminal 7 ends. As will be described later, when the importance level is notified, the reception confirmation period corresponding to the importance level is also notified together with the importance level. Also, as shown in FIG. 16, the importance is set to be higher as the reception success rate is higher. For example, the degree of importance of the external terminal (1) is 100%, and the degree of importance of the external terminal (2) is 5%.

  The processing in steps S111 to S114 is processing on the server 3 side. On the other hand, the processing of steps S131 to S136 is processing on the external terminal 7 side. In step S111, the importance is notified. In step S112, a reception confirmation period corresponding to the importance is notified. In step S113, it is determined whether or not a notification that it has been determined that there has been a change in the position of the apparatus has been received. When it is determined that a notification that it has been determined that there has been a change in the position of the apparatus has been received (step S113; Y), the processing moves to step S114. On the other hand, when it is determined that a notification that it has been determined that there is a change in the position of the apparatus is not received (step S113; N), the process of step S113 is in a standby state. In step S114, the map information of the floor map is updated, and the processing on the server 3 side ends.

  In step S131, the importance level is acquired. In step S132, a reception confirmation period corresponding to the importance is acquired. In step S133, it is determined whether or not the current position information of the own device is the same as when a beacon signal has been received in the past. When it is determined that the current position information of the own device is the same as when a beacon signal has been received in the past (step S133; Y), the process proceeds to step S134. on the other hand. When it is determined that the current position information of the own device is not the same as when a beacon signal was received in the past (step S133; N), the processing on the external terminal 7 side ends. In step S134, it is determined whether or not the period during which no beacon signal is received from the device exceeds the reception confirmation period. When it is determined that the period during which no beacon signal is received from the device exceeds the reception confirmation period (step S134; Y), the process proceeds to step S135. On the other hand, when it determines with the period which does not receive a beacon signal from an apparatus not exceeding a reception confirmation period (step S134; N), a process returns to step S133. In step S135, it is determined that there is a change in the position of the apparatus. In step S136, the server 3 is notified that it has been determined that there has been a change in the position of the apparatus, and the processing on the external terminal 7 side ends.

  As shown in FIG. 18, for example, if the importance is in the range of 80% to 100%, the reception confirmation period is 1 hour. Therefore, since the importance is 100%, the external terminal (1) notifies the server 3 that there is a change in the position of the device when the beacon signal is not received for 1 hour. For example, if the importance is in the range of 0% to 20%, the reception confirmation period is 10 days. Therefore, since the importance is 5%, the external terminal (2) notifies the server 3 that there is a change in the position of the device when the beacon signal is not received continuously for 10 days.

  That is, as the beacon signal reception success rate increases, the time required to determine whether or not the position of the device has changed is shortened. The reception confirmation period is set by the processing in steps S151 to S154. In step S151, it is determined whether a reception confirmation period is set according to the importance. When it is determined that the reception confirmation period is set according to the importance (step S151; Y), the process of setting the reception confirmation period of the external terminal 7 ends. On the other hand, when it is determined that the reception confirmation period is not set according to the importance (step S151; N), the process of step S152 proceeds. In step S152, the beacon signal transmission interval is acquired. In step S153, an update interval for reflecting the change in the position of the apparatus on the floor map is acquired. In step S154, the reception confirmation period is set based on the transmission interval of the beacon signal and the update interval for reflecting the change in the position of the apparatus in the floor map, and the processing for setting the reception confirmation period of the external terminal 7 ends. .

  FIG. 20 is a diagram illustrating an example of a floor map displayed on the external terminal 7 according to the first embodiment and updated according to a change in the position of the apparatus. When the server 3 receives the display request for the device position information from the external terminal 7, the server 3 stores the floor map stored as the map information, the device position information of the printer (A) called (F) column (2) row of the floor map, and , Device position information including a change in the position of the device is transmitted to the external terminal 7. The external terminal 7 can display a floor map as shown in FIG. 20 by superimposing the position of the printer (A) and the apparatus position information including the change in the position of the apparatus on the floor map acquired from the server 3. In the example of FIG. 20, the past position of the printer (A) is displayed on the floor map, and “! Move” is displayed so that the movement of the apparatus becomes clear. The changed printer (A) may be simply not displayed on the floor map.

  As described above, according to the information processing system 1 to which the present disclosure is applied, when a beacon signal transmitted at a constant transmission interval is received, based on the location information of the external terminal 7 and the time information. Whether or not there is a change in the position of the apparatus, and if there is a change in the position of the apparatus, is the apparatus within a range where a beacon signal can be transmitted to the external terminal 7 by reflecting the change in the position of the apparatus on the floor map? Since the determination is made at regular intervals, even if the position of the apparatus changes, that fact can be immediately reflected in the floor map.

  In addition, based on the device identification information included in the beacon signal, by specifying the source of the beacon signal among a plurality of devices, it is possible to specify from which device the beacon signal is transmitted, Changes in the position of the device can be accurately reflected on the floor map.

  Further, by identifying the external terminal 7 that is the destination of the beacon signal based on the external terminal identification information, it is clear to which external terminal 7 the device has transmitted the beacon signal. The position of the device that is the source of the beacon signal can be estimated using the position of 7 as a reference.

  Further, for each external terminal 7 specified by the external terminal identification information, an external number is determined based on the number of beacon signals transmitted from the device to the external terminal 7 and the number of beacon signals received by the external terminal 7 from the device. By obtaining the importance of the terminal 7, it is possible to identify the external terminal 7 that has received the beacon signal most frequently from the apparatus. Therefore, it is possible to identify the external terminal 7 that is closest to the apparatus. Therefore, it is possible to specify the external terminal 7 to which the change in the position of the apparatus is reflected most immediately.

  In addition, when the period during which no beacon signal is received exceeds the reception confirmation period according to the importance, it is determined that there is a change in the position of the apparatus, and it is determined that there is a change in the position of the apparatus. Is notified, by updating the map information of the floor map, it is possible to determine whether or not there is a change in the position of the device according to the positional relationship between the external terminal 7 and the device, and the position of the device thus determined Since the presence or absence of the change can be reflected in the map information of the floor map, the presence or absence of a change in the position of the device can be determined according to the arrangement status of the external terminals 7 existing around the device. Therefore, the position of the apparatus can be monitored using the external terminal 7.

  Further, the reception confirmation period is set based on a constant transmission interval at which a beacon signal is transmitted from the device to the external terminal 7 and an update interval in which a change in the position of the device is reflected in the floor map, Since the update interval is set to be longer than the constant transmission interval, the reception confirmation possible interval can be set between the constant transmission interval and the update interval. Therefore, the reception confirmation period can be set based on the reception confirmation possible interval. Therefore, the reception confirmation period can be set appropriately.

  Further, when the current location information of the external terminal 7 is the same as when the beacon signal was received in the past, it is determined whether or not the period during which the beacon signal is not received exceeds the reception confirmation period, Since it is possible to determine whether the user who owns the external terminal 7 has moved, it is possible to determine which position of the user who owns the external terminal 7 and the device has changed. Therefore, it is possible to increase the accuracy of the determination of whether or not there is a change in the position of the device.

  Further, by identifying the source of the beacon signal among a plurality of devices based on the MIB information included in the beacon signal, from which device the beacon signal is transmitted in a communication environment in which a network device compliant with SNMP is used. Since it is possible to specify whether it has been transmitted, a change in the position of the apparatus can be accurately reflected on the floor map in a multi-vendor network environment.

  Also, based on the signal strength of the beacon signal, by specifying the source of the beacon signal that exists on the same floor as the external terminal 7, it is assumed that the devices that are the source of the beacon signal have been placed on different floors, respectively. However, since it is possible to identify a device having a strong signal strength as a device existing on the same floor as the external terminal 7, it is possible to enhance a determination system for whether or not there is a change in the position of the device.

  In addition, a device that detects the position of the external terminal 7 includes a GPS sensor 774 and at least one of an acceleration sensor 771, a gyro sensor 772, and a magnetic direction sensor 773, so that the position of the external terminal 7 can be accurately determined. Since it can detect, the reliability of the determination of the presence or absence of the change of the position of an apparatus can be improved.

Embodiment 2. FIG.
In the second embodiment, not the image forming apparatus 5 but the vending machine 9 is a component of the information processing system 1 as a device, and Wi-Fi (registered trademark) is used as a beacon signal instead of iBeacon (registered trademark). To do. In the second embodiment, descriptions of the same configurations and functions as those in the first embodiment are omitted.

  FIG. 21 is a diagram illustrating an overall configuration example of the information processing system 1 according to the second embodiment to which the present disclosure is applied. The vending machine 9 is equipped with a Wi-Fi (registered trademark) access point function, and a packet called a beacon signal is transmitted at a constant transmission interval. The packet includes MAC address information. FIG. 22 is a block diagram illustrating a configuration example of the vending machine 9 according to the second embodiment. The vending machine 9 includes a controller 91, a storage unit 92, a communication unit 94, and a beacon transmission unit 95. The controller 91 includes a communication control unit 911 and a beacon control unit 912. Since the controller 91, the storage unit 92, the communication unit 94, the beacon transmission unit 95, the communication control unit 911, and the beacon control unit 912 perform the same functions as those included in the image forming apparatus 5, here, The description is omitted. However, unlike the storage unit 52 of the image forming apparatus 5, the storage unit 92 stores MAC address information.

  That is, the device such as the vending machine 9 includes the MAC address information in the device identification information. Therefore, the extraction instruction is for extracting the MAC address information. Therefore, the transmission source specifying instruction specifies a device that is a transmission source of the beacon signal based on the MAC address information extracted by the extraction instruction.

  FIG. 23 is a flowchart illustrating an example of processing for specifying a device based on MAC address information in an environment where a plurality of devices according to the second embodiment exist. In step S171, MAC address information is extracted. In step S172, based on the MAC address information, a device serving as a beacon signal transmission source is identified from among a plurality of devices, and the process of identifying a device based on the MAC address information in an environment where a plurality of devices exist is completed.

  Since the vending machine 9 is less important than the image forming apparatus 5 to notify the frequency of movement or the fact that it has moved, the reception confirmation period is set to be longer than that of the image forming apparatus 5. The FIG. 24 is a diagram illustrating an example of items of importance and reception confirmation period of the external terminal 7 in the data table held by the server 3 according to the second embodiment. As shown in FIG. 24, for example, if the importance is in the range of 80% to 100%, the reception confirmation period is set to one day. For example, if the importance is in the range of 0% to 20%, the reception confirmation period is set to 90 days.

  From the above description, according to the information processing system 1 to which the present disclosure is applied, by specifying the source of the beacon signal among a plurality of devices based on the MAC address information included in the beacon signal, the Ethernet (registered trademark) ) In a communication environment where network equipment conforming to the standard is used, it is possible to specify from which device the beacon signal is sent, so the change in the position of the device can be accurately performed in various network environments. It can be reflected in the floor map.

  As described above, the information processing system 1 to which the present disclosure is applied has been described based on the embodiment. However, the present disclosure is not limited to this, and changes may be made without departing from the gist of the present disclosure.

  For example, although an example in which one device for transmitting a beacon signal such as a printer or a vending machine is described has been described, the present invention is not limited thereto, and a plurality of devices for transmitting a beacon signal such as a printer or a vending machine are provided. It may be arranged.

  Note that the series of processes described above can be executed by hardware or can be executed by software. When a series of processing is executed by software, a program that configures the software installs various programs and can execute various functions from a recording medium that records the program, or It is installed via the Internet or the like.

  Also, if the information size at the time of transmission is eliminated in iBeacon (registered trademark), MIB information may be acquired without specifying an OID.

  Moreover, although an example which calculates | requires importance based on the transmission frequency of the beacon signal which the apparatus transmitted, and the reception frequency of the beacon signal which the external terminal 7 received was demonstrated, it is not limited to this. For example, the beacon signal reception success rate of each external terminal 7 is determined based on the number of beacon signals transmitted by the device and the number of transmissions of server transmission information including beacon signals received by the external terminal 7 to the server 3. It is good also as a calculation and making the calculation result the importance.
