Since the RFID detection operation is performed wirelessly, it is impossible to determine whether or not the detection has been made by visual observation. Therefore, the detection result is displayed using a lamp or the like. Describes that when an approach to the monitoring area is detected, the lamp is turned on to notify the person in charge of monitoring to that effect.
However, the above prior art has a problem that a lamp that is turned on at the time of RFID detection is fixed, and a flexible system operation cannot be performed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic diagram of a schematic configuration when the processing control system of the present invention is applied to an in-house management system.
The in-house management system 1 manages the location and behavior of employees (or in-house temporary visitors) within the company. As shown in FIG. 1, the entrance / exit of each room and the main passage 1 </ b> A are provided with passing gates 2, and the in-house management system 1 identifies employees X that have passed through these passing gates 2, Manage the location and behavior of employee X.

  The configuration of the internal management system 1 will be described. The internal management system 1 includes an ID card 4 having a contactless wireless communication function possessed by the employee X, and loop antennas 6-1 to 6-3 provided in the passing gate 2. Communication control devices 8-1 to 8-3 connected to the loop antennas 6-1 to 6-3, and a processing control device in which the communication control devices 8-1 to 8-3 are connected via the communication network 9. 10, a server 11 that centrally manages information to be referred to by the processing control device 10, and one or a plurality of operation control of the controlled devices 12-1 to 12-6 under the control of the processing control device 10. Device controllers 13-1 to 13-4 for performing detection, and the IDs for detection recorded on the ID card 4 by the communication control devices 8-1 to 8-3 via the loop antennas 6-1 to 6-3. Configured to be readable That.

Loop antennas 6-1 to 6-2 are provided on the floor surface of the passage route of the passage gate 2. The loop antenna 6 is formed, for example, in a substantially rectangular shape having a size of about 0.6 meters × 1.5 meters, and is non-directional and has a communicable distance of several meters (for example, about 5 meters).
The loop antennas 6-1 to 6-2 of the in-house management system 1 are arranged around the loop antennas 6-1 to 6-2 in addition to the wireless tag 20 that is the original communication partner, as shown in FIG. The wireless tag described later, which is provided in the ID card 4 and the influence of the noise N generated from the electrical wiring and various electronic devices, the influence of inter-antenna interference between the loop antennas 6-1 to 6-2 arranged in the vicinity A signal affected by inter-tag interference is input.

  In the above configuration, the controlled device 12-1 is arranged in the vicinity of the pass gate 2 corresponding to the loop antenna 6-1, and when the ID card 4 passes through the pass gate 2, it is lit in a predetermined color for a predetermined time. Light. The controlled devices 12-2 to 12-4 are lights arranged on a security panel arranged in the security room SR, and are turned on or off in various modes according to the detection state of the ID card 4. The controlled device 12-5 is a light that is disposed in the vicinity of the pass gate 2 corresponding to the loop antenna 6-3, and is lit in a predetermined color for a predetermined time when the ID card 4 passes through the pass gate 2. . The controlled device 12-6 is a video camera that takes a picture of a passing person passing through the passage 1A.

FIG. 2 is a block diagram schematically showing a functional configuration of the ID card.
The ID card 4 incorporates an active wireless tag 20 that realizes a non-contact wireless communication function using long waves. As shown in FIG. 2, the wireless tag 20 includes an employee ID 22A, which is identification information of the employee X, and a memory 22 that stores a detection ID 22B corresponding to the employee ID 22A, an RF unit 24 for wireless communication using long waves, A control unit 26 that controls these components, an antenna 28 that receives radio waves radiated from the loop antenna 6 of the passage gate 2, and a power supply unit 29 that supplies power to the wireless tag 20 are provided, and the operation mode is a standby mode. In some cases, when the wake-up radio waves radiated from the loop antennas 6-1 to 6-3 of the pass gate 2 are received, the operation is performed in the normal mode in response to the reception of the wake-up radio waves, and the detection ID 22B Send.

Here, the employee ID and the detection ID will be described.
In the present embodiment, the employee ID 22A is not transmitted when passing through the passing gate 2, and only the detection ID 22B is transmitted. This is because the employee ID 22A can be arbitrarily set by the builder of the in-house management system 1, and is substantially equivalent to the case where a bit of “0” and a bit of “1” are randomly generated depending on the input contents. This is because there is a possibility that the bit arrangement is difficult to distinguish from external noise or the like.
On the other hand, the detection ID employs a temporally redundant pattern in which “0” bits or “1” bits are serially continuous, and is set to be easily distinguished from external noise.

Specifically, when 32 bits are assigned as the employee ID 22A (address space 4 GB), 32 bits are also assigned to the detection ID 22B, the number of redundant bits is 16 bits, and the actual address space is 64 kB. Therefore, when the detection ID is used for user identification, it is possible to simply identify 65535 people.
Next, the format of a transmission signal for transmitting the detection ID by the wireless tag 20 will be described.
In the present embodiment, this transmission signal is a 32-bit bit string signal having a predetermined bit length, and the detection ID 22B is stored using all of this bit string. In the present embodiment, the detection information included in the detection ID 22B is 16 bits long and is limited to a value of 0000h to FFFFh.
Simply, an address space for 64 kB out of a 4 GB address space represented by 00000000h to FFFFFFFFh in which each bit is duplicated and arranged is allocated to the detection ID.
Therefore, the processing control apparatus 10 can identify the employee ID 22A from the detection ID 22B by referring to a table in which the correspondence relationship between the detection ID 22B and the employee ID 22A is stored in advance.

FIG. 3 is a block diagram showing a functional configuration of the communication control apparatus.
As shown in this figure, the communication control device 8 includes a control unit 30 that centrally controls each unit, a wireless communication unit 32 that communicates with the wireless tag 20 of the ID card 4 via the loop antenna 6, and a wired LAN or And a network interface (I / F) 34 connected to a communication network 9 such as a wireless LAN.

  The wireless communication unit 32 includes an RF circuit and a baseband circuit for wireless communication (not shown), and is controlled by the control unit 30 at every predetermined wake-up timing (for example, every fixed time of about 5 times per second). ), A wake-up signal for starting electromagnetic communication with the wireless tag 20 is radiated as a radio wave by changing the current flowing through the loop antenna 6 to cause a change in the magnetic field. When the ID card 4 is present in the communicable region R due to the emission of the radio wave, the wireless tag 20 of the ID card 4 shifts from the standby mode to the normal operation mode, and the detection ID 22B is transmitted. The wireless communication unit 32 receives the data.

The control unit 30 includes a CPU as a program execution unit, a RAM used as a work area of the CPU, a ROM that stores various programs, and the like. In the present embodiment, the control unit 30 is input from the wireless communication unit 32. A time stamp giving unit 38 that gives the current time as a time stamp to the detection ID 22B, and a loop antenna 6-X [X: 1 to 1 connected to the own device (or to the own device) to the detection ID 22B. 3]) and a device ID assigning unit 39 that assigns a device ID uniquely assigned in advance.
Then, every time the detection ID 22B is received by the wireless communication unit 32, the control unit 30 assigns a time stamp and a device ID, and sequentially transmits them from the network I / F 34 to the processing control device 10 via the communication network 9. .
Note that the plurality of communication control devices 8 arranged in the plurality of passing gates 2 measure time synchronized with each other in order to be able to compare the time stamps assigned thereto.

FIG. 4 is a block diagram illustrating a functional configuration of the processing control apparatus.
The processing control device 10 manages the employee X that has passed the corresponding passage gate 2 based on the detection ID, time stamp, and device ID transmitted from the communication control device 8 provided in each of the passage gates 2. It is.
Specifically, as illustrated in FIG. 5, the processing control apparatus 10 includes a control unit 40, a network I / F 42, a database unit 44, and a database access unit 46.
The control unit 40 centrally controls each unit of the device itself, and includes a CPU as a program execution unit, a RAM that functions as a work area of the CPU, a ROM that stores various programs and setting data, and the like. Yes.
The network I / F 42 is connected to the communication network 9, receives the employee ID, received signal strength, time stamp, and device ID from each of the communication control devices 8 via the communication network 9, and outputs them to the control unit 40.

The database unit 44 stores various databases, and includes an employee ID-detection ID correspondence database unit 44A, a location record database unit 44B that records the location of each employee, and a process control database unit 44C. I have.
First, the employee ID-detection ID correspondence database unit 44A of the database unit 44 will be described.
The employee ID-detection ID correspondence database unit 44A functions as a correspondence storage unit. In the employee ID-detection ID correspondence database unit 44A, the issued employee ID 22A has a one-to-one correspondence with the detection ID. Attached and registered.
In this case, in the employee ID, an ID corresponding to a temporary visitor, that is, a valid employee ID including a guest ID is registered. In this embodiment, as described above, the employee ID is arbitrarily set to a value that can be expressed by a predetermined bit length (in this embodiment, 32 bits: 00000000h to FFFFFFFFh) and a unique value. Although this employee ID 22A is recorded in the wireless tag 20, it is not used in communication with the communication control device 8 via the loop antenna 6.

On the other hand, the detection ID 22B is set when the system is constructed, and is an ID transmitted from the wireless tag 20 side to the communication control device 8 side in communication between the wireless tag 20 and the communication control device 8. It is. In the present embodiment, a value that can be expressed by bits excluding redundant bits in a predetermined bit length is set. In the present embodiment, since the redundant bits are 16 bits among the 32 bits constituting the detection ID, values (0000h to FFFFh) that can be expressed in 16 bits are set.
In this case, the detection ID 22B employs a bit string pattern in which bits are arranged so that “0” bits or “1” bits have redundancy in the time axis direction in which serially continuous bits are used. Is set to be easy to distinguish.
In other words, by configuring the detection ID with a bit string in which bits are arranged so as to have redundancy in the time axis direction during transmission, the transmission signal is buried in noise compared to the case where an arbitrary unique ID is used for communication. Probability can be lowered.
Here, the bit string in which bits are arranged so as to have redundancy in the time axis direction means a bit string having a bit arrangement that is difficult to obtain when bits are randomly arranged, for example, “1” or “0”. Refers to an arrangement in which appears several times in succession. This is because noise can be regarded as being equivalent to a case where bits are randomly arranged, and is clearly separated from this.
That is, in the detection ID, bits are arranged so as to have redundancy in the time axis direction at the time of transmission so that the bit arrangement (= noise) obtained when the value of each bit is changed randomly is not obtained. Therefore, the possibility that the randomly generated noise (noise) matches the detection ID is extremely low. Specifically, only a bit arrangement that is unlikely to be obtained as noise, such as “1111000011110000”, is used as a 16-bit detection ID.
Further, the bit string constituting the detection ID is configured to be discretely positioned in the ID assignable space that can be expressed by the number of bits of the detection ID. Here, for example, when “1111000011110000” is set as one of 16-bit detection IDs, “1111000011110001” and “0111000011110001” differing only in 1 bit or 2 bits are used. For example, a bit arrangement different by 4 bits or more, such as “1111000011111111” or “0000000011111111”, is used. In other words, the detection ID is assigned a jump value in the ID assignable space that can be expressed by the number of bits of the detection ID. Therefore, it is less likely that different detection IDs are erroneously detected as the same detection ID due to noise, and there is no approximate bit arrangement. The ID can be specified.

Here, a specific method of generating the detection ID 22B will be described.
FIG. 5 is a flowchart of detection ID generation processing.
This generation process can be performed by the process control device 10.
First, the processing control apparatus 10 sets the calculation variable i = 0 (step S1).
Next, the processing control apparatus 10 sets one piece of 16-bit integer data Z (0 ≦ Z ≦ 65535) (step S2).
Subsequently, the processing control apparatus 10 extracts the lower 4 bits of the data Z (step S3).
Subsequently, the processing control apparatus 10 calculates the logical sum of the extracted 4-bit value and the value obtained by shifting the value to the left by 4 bits (that is, the value obtained by multiplying the original value by 16) to obtain the upper 4 An 8-bit value having the same value in the lower 4 bits is substituted into the variable dmc (i) (step S4).

Next, 1 is added to the variable i to obtain a new variable i (step S5), and it is determined whether i = 4 (step S6).
If it is determined in step S6 that i ≠ 4 (step S6; No), the integer data Z is shifted to the right by 4 bits to set the value as new data Z (step S7), and the process proceeds to step S3. Thereafter, the same processing is repeated.
If it is determined in step S6 that i = 4 (step S6; Yes), the variable dmc (3) is shifted by 24 bits to the left, dmc (2) is shifted by 16 bits to the left, and dmc (1 ) Is shifted to the left by 8 bits and the value of dmc (0) is ORed to obtain a 32-bit value (step S8).
That is, in each bit (31st to 0th bits) constituting the obtained 32-bit value, the variable dmc (3) is the 31st to 24th bits, and dmc (2) is the 23rd to 24th bits. 16 bits, dmc (1) is the 15th to 8th bits, and dmc (0) is the 7th to 0th bits.

Next, the obtained 32-bit value is not collected in a specific space within the ID allocation space (equivalent to 4 GB) that can be expressed by the number of bits of the ID 22B for detection (= 32 bits), and is discretely positioned. The 31st to 1st bits of the obtained 32-bit value are shifted right by 1 bit, and the value with the 0th bit being the 31st bit is set as the detection ID 22B (step S29).
As a result, 65536 detection IDs can be generated by changing Z from 0 to 65535. In practice, it is only necessary to generate detection IDs corresponding to the number of employee IDs 22A managed by the processing control device 10.
The above-described generation process of the detection ID 22B is an example, and it is specified in an ID allocation space that has the same redundancy and redundancy along the time axis direction and can be expressed by the number of bits of the detection ID 22B. Other generation processes may be used as long as they can be discretely positioned without being gathered in the space.

Next, the location record database unit 44B of the database unit 44 will be described.
The location record database unit 44B of the database unit 44 records the employee ID of the employee X who has passed through the passing gate 2 by the control unit 40 together with the passing date and time. Therefore, based on the record of the location record database unit 44B, it is possible to manage the current location of the employee, the entry / exit time, the stay time of the employee X, and the like.
Next, the processing control database unit 44C of the database unit 44 will be described.
FIG. 6 is an explanatory diagram of the data format of the process control database unit.
The process control database unit 44C includes ID data 51 for storing employee IDs to be processed, and target date / time data for storing target dates / times as conditions for controlling the controlled devices 12-1 to 12-6. 52, detection gate data 53 for specifying a passing gate as a condition for controlling the controlled devices 12-1 to 12-6, and controlled devices 12-1 to 12-6 to be controlled In addition, correspondence processing data 54 for specifying the processing content is provided.
Corresponding processing data 54 includes device controller ID data 55 for specifying controlled devices 12-1 to 12-6 to be controlled, and processing commands to be sent to controlled devices 12-1 to 12-6 to be controlled. Alternatively, a corresponding processing command 56 that stores a processing command group is provided.
In this case, the ID data 51 includes ID data for all employees, ID data for employees in a specific department (such as the administrative department, the accounting department, and the research department) according to the control mode. ID data for employees other than a specific department can be set.
The target date / time data can specify not only the date and time, but also the day of the week, holidays, holidays, and time zones (business hours, non-business hours, nighttime, etc.).

  Further, the control unit 40 refers to the employee ID-detection ID correspondence database of the database unit 44 via the database access unit 46 based on the detection ID 22B, time stamp and device ID received from the communication control device 8, The employee ID 22A corresponding to the received detection ID 22B is identified, the employee X corresponding to the employee ID 22A is identified through which passing gate 2, and the employee ID of the employee X is recorded based on the identification result. It is recorded in the database unit 44B.

In this case, when the employee ID 22A corresponding to the received detection ID 22B does not exist in the employee ID-detection ID correspondence database unit 44A, the control unit 40 indicates that the detection ID 22B is a transmission signal from the wireless tag 20. The received data received from the communication control device 8 is discarded and the received data whose data format accidentally matches the predetermined format due to the noise N, inter-antenna interference IA, or inter-tag interference Receive data affected by IT is discarded.
Accordingly, since error detection correction processing of the received data is not performed, the calculation load in the processing control apparatus 10 can be reduced, and a location record different from the actual due to the detection ID read by accident is located in the location record database section. 44B is not recorded.

  Further, since the communicable area of the loop antenna 6 is at most several meters, even if the employee X walks or runs and passes through the passing gate 2, each communication control device 8 is several times per second (this In the embodiment, the ID card 4 possessed by the employee X is detected by each communication control device 8 a plurality of times continuously by performing reception five times.

Under such a configuration, in the in-house management system 1, as shown in FIG. 1, when the employee X approaches the passing gate 2 trying to pass the passing gate 2, the employee X is connected via the loop antenna 6-1. Is detected by the communication control device 8-1 that repeatedly performs detection at regular intervals.
As a result, the detection ID 22B recorded on the wireless tag 20 of the ID card 4 is received by the communication control device 8-1 of the passing gate 2, and the time stamp and the device ID together with the detection ID 22B are received data as the processing control device 10. Are sequentially input.
As a result, the processing control device 10 refers to the employee ID-detection ID correspondence database unit 44A via the database access unit 46, reads the employee ID corresponding to the detection ID 22B, and stores the location record database. The location record is recorded in the section 44B.
Further, by referring to the processing control database unit 44C, for example, the controlled device 12-1 that is a light is lit in a predetermined color for a predetermined time via the device controller 13-1.

Next, a specific operation of the communication control device 8 will be described.
FIG. 7 is a process flowchart of the communication control apparatus.
The control unit 30 of the communication control device 8 determines whether or not it is a wake-up timing for shifting the wireless tag 20 of the ID card 4 from the standby mode to the normal operation mode (step S11).
This wake-up timing is variably set, and is gradually set to a longer time according to the elapsed time since the ID card 4 finally passed through the pass gate 2, and a new pass gate 2 When the ID card 4 passes, the time is reset to the shortest.
If the wake-up timing has not yet been reached in the determination in step S11 (step S11; No), the control unit 30 enters a standby state.

If it is determined in step S11 that the wake-up timing is reached, a wake-up signal is transmitted for a predetermined time to the wireless tag 20 of the unspecified ID card 4 that may be located near the pass gate 2. Specifically, an unmodulated carrier wave is transmitted as a wake-up signal, for example, for 160 ms.
Next, the control unit 30 determines whether or not there is a response from the wireless tag 20 of any ID card 4 (step S13).
If there is no response from the wireless tag 20 of any ID card 4 in the determination in step S13, the control unit 30 shifts the process to step S11 again and enters a standby state.
If there is a response from the wireless tag 20 of any ID card 4 in the determination in step S13, a reading process for reading the detection ID 22B transmitted from the wireless tag 20 is performed (step S14).

Next, the control unit 30 determines whether or not the detection ID 22B has been read (step S15).
In the determination of step S15, when the detection ID 22B is read (step S15; Yes), the control unit 30 gives a time stamp to the read detection ID 22B by the time stamp giving unit 38, and gives a device ID. A unit ID is assigned by the unit 39, and a detection ID transmission process is performed for transmission to the processing control apparatus 10 via the network interface unit 34 (step S16), and the process proceeds to step S14.

Here, the operation of the processing control apparatus 10 that has received the detection ID will be described.
FIG. 8 is a process flowchart of the process control apparatus.
When the control unit 40 of the processing control device 10 receives the detection ID, time stamp, and device ID from the communication control device 8 via the network interface unit 42 (step S21), the control unit 40 of the database control unit 10 receives the detection ID, time stamp, and device ID. The employee ID-detection ID correspondence database unit 44A is referred to (step S22).
Next, the control unit 40 determines whether or not the received detection ID exists in the employee ID-detection ID correspondence database unit 44A, that is, there is an employee ID (arbitrary ID) corresponding to the detection ID on a one-to-one basis. It is determined whether or not to perform (step S23).

If it is determined in step S23 that the received ID does not exist in the employee ID-detection ID correspondence database unit 44A (step S23; No), the control unit 40 discards the received data and ends the process. (Step S26).
On the other hand, in the determination of step S23, when the received detection ID exists in the employee ID-detection ID correspondence database unit 44A (step S23; Yes), the control unit 40 transmits the database via the database access unit 46. The location record database unit 44B of the unit 44 is accessed to update the employee location record data corresponding to the employee ID corresponding to the detection ID (step S24).
Specifically, the control unit 40 records the time corresponding to the time stamp and the location corresponding to the device ID in the location record list of the location record database unit 44B.

Thus, according to the in-house management system 1 of the present embodiment, the processing control apparatus 10 can easily grasp the detection ID transmitted by the wireless tag 20 in a state of being separated from the noise, so that the arbitrary ID assigned arbitrarily Can be separated from noise even when the communication situation is poor and the signal strength is low, and as a result, an arbitrary ID corresponding to the detection ID is identified one-to-one. can do.
That is, the employee X that has passed through the passing gate 2 can be easily identified.

  Next, the control unit 40 performs controlled device control processing for controlling the controlled devices 12-1 to 12-6 (step S25).

FIG. 9 is a process flowchart of the controlled apparatus control process.
First, the control unit 40 refers to the process control database unit 44C using the employee ID as a search key (step S31).
And the control part 40 discriminate | determines whether ID data 51 corresponding to employee ID exists (step S32).
If it is determined in step S32 that the corresponding ID data 51 does not exist (step S32; No), it is not necessary to control any of the controlled devices 12-1 to 12-6, and the process is terminated.
If it is determined in step S32 that the corresponding ID data 51 exists (step S32; Yes), the control unit 40 refers to the target date / time data 52 corresponding to the ID data 51 and determines the current date / time (date, day of the week). It is determined whether or not (time, time zone, etc.) belongs to the date (date, day of week, time, time zone, etc.) corresponding to the target date / time data 52 (step S33).

If it is determined in step S33 that the current date / time does not belong to the date / time corresponding to the target date / time data 52 (step S33; No), it is not necessary to control any of the controlled devices 12-1 to 12-6. Therefore, the process ends.
If it is determined in step S33 that the current date / time belongs to the date / time corresponding to the target date / time data 52 (step S33; Yes), the control unit 40 refers to the process control database unit 44C to the ID data 51. With reference to the corresponding detection gate data 53, it is determined whether or not the received device ID corresponds to the detection gate data 53 (step S34).

If it is determined in step S34 that the received device ID does not correspond to the detection gate data 53 (step S34; No), it is not necessary to control any of the controlled devices 12-1 to 12-6. Therefore, the process ends.
If it is determined in step S34 that the received device ID corresponds to the detection gate data 53, it corresponds to the ID data 51 in order to control one of the controlled devices 12-1 to 12-6. Referring to the corresponding processing data 54, the device controller ID data 55 and the corresponding processing command 56 for specifying any one or more of the controlled devices 12-1 to 12-6 are read out, and the corresponding device controller ID data 55 is read out. A processing command corresponding to the corresponding processing command data 56 is sent to any one of the device controllers 13-1 to 13-4 via the communication network 9 to be processed.

Here, a specific example will be described.
First, it is assumed that the processing control database unit 44C has the following two sets of data (1) and (2). In the following description, the contents of each data are expressed in an easy-to-understand manner, not the actual data contents.
(1) ID data 51 = Employee number 0011
Target date / time data 52 = Weekdays from 9:00 to 17:00 Detection gate data 53 = Passing gate corresponding processing data 54 corresponding to the loop antenna 6-2:
Device controller ID = device controller 13-2
Corresponding processing command = controlled device 12-1, green lighting for 30 seconds (2) ID data 51 = employee number 0011
Target date and time data 52 = Weekdays other than 9:00 to 17:00 Detection gate data 53 = Passing gate corresponding processing data 54 corresponding to the loop antenna 6-2:
Device controller ID = device controller 13-2, 13-4
Corresponding processing command = controlled device 12-1 lit red for 1 minute
= Controlled device 12-6, shooting

In the case of the above example, if the employee of employee number 0011 enters the office room OR in the time zone from 9:00 to 17:00 on weekdays, the control unit 40 of the processing control device 10 passes through the loop antenna 6-2. That is detected, the process control database unit 44C is referred to, the device controller 13-2 is controlled, and the light as the controlled device 12-1 in the security room SR is lit in green for 30 seconds. It becomes.
On the other hand, if the employee with the employee number 0011 enters the office OR in the time zone from 9:00 to 17:00 on holidays, the control unit 40 of the processing control apparatus 10 passes through the loop antenna 6-2. And the process control database unit 44C is referred to, the device controller 13-2 is controlled, and the light that is the controlled device 12-1 in the security room SR is lit in red for 1 minute, In order to record the fact that the user has entered the room, the apparatus controller 13-4 is controlled to activate the video camera, which is the controlled apparatus 12-6 provided at the corner of the passage 1A, to perform shooting.
As described above, even when the same employee ID is detected, the controlled devices 12-1 to 12-6 can be freely controlled according to the contents of the processing control database unit 44C. It becomes. Furthermore, even if it is desired to change the control content, it is only necessary to change the content of the processing control database unit 44C, so that management is easy.

By the way, since the flexible configuration as described above is adopted, it is possible to set the plurality of data constituting the processing control database unit 44C without taking consistency.
In order to prepare for such a case, in the present embodiment, a database in which priorities for preserving processing consistency are stored in the server 11 in advance is constructed. Therefore, when the processing control apparatus 10 can determine it, the processing control apparatus 10 performs control with consistency, and controls other items under the control of the server 11.
Specifically, it is assumed that the following two sets of data (3) and (4) are set in the database unit 44C.

(3) ID data 51 = Employee number 0011
Target date and time data 52 = Weekdays other than 9:00 to 17:00 Detection gate data 53 = Passing gate corresponding processing data 54 corresponding to the loop antenna 6-2:
Device controller ID = device controller 13-2
Corresponding processing command = controlled device 12-1, red lighting for 1 minute (4) ID data 51 = employee number 0141
Target date and time data 52 = Weekdays other than 9:00 to 17:00 Detection gate data 53 = Passing gate corresponding processing data 54 corresponding to the loop antenna 6-2:
Device controller ID = device controller 13-2
Corresponding processing command = controlled device 12-1, green lighting 30 seconds

In this case, the control of the light which is the controlled device 12-1 is actually performed by a set of commands of a lighting control command and a lighting control command.
Therefore, for example, the employee with the employee number 0011 passes through the passing gate 2 corresponding to the loop antenna 6-2 at 14:00 on the holiday, and the employee with the employee number 0141 has the loop antenna 6 at 14:00:10. -2 passes through the passage gate 2 corresponding to -2, the light which is the controlled device 12-1 lights in red at 14:00:00, and lights up in green at 14:00:10, It will turn off at 0:00:40.

Therefore, in the security room SR, the employee with the employee number 0011 is almost unconfirmed.
Therefore, in such a case, for example, the processing control apparatus 10 performs processing so as to repeat green lighting and red lighting every 2 seconds from 14:00:10 to 14:00:40. Send a command.
As a result, from 14:00:10 to 14:00:10, the light that is the controlled device 12-1 is lit red, and from 14:00:10 to 14:00:40 Green lighting and red lighting are repeated every 2 seconds, and it lights in green from 14:00:40 to 14:01:00.

Therefore, it is possible to confirm two employees in the security room SR.
Similarly, when the presence of any employee is detected, if the light that is the controlled device is turned on, the presence of the employee is first detected and a lighting control command is sent. After that, until the presence of the employee is no longer detected, the process control device 10 may not send the extinction control command to the corresponding device controller.
The above description is a case where it is not possible to determine whether or not there is inconsistency until the processing control apparatus 10 actually refers to the processing control database unit 44C. Therefore, it is desirable to detect a steady mismatch.

  According to the in-house management system 1 of the present embodiment, the processing control device 10 determines whether or not the detection ID 22B detected based on the received data is registered in the employee ID-detection ID database unit 44A. Since it is determined whether or not the employee ID is the wireless tag 20, it is possible to easily exclude an employee ID detected by passing an unauthorized wireless tag or an already expired wireless tag or receiving noise. Further, in such a case, the in-house management system 1 is provided with a speaker device or a display device for alarm notification as a controlled device, and is configured to notify that via the processing control device 10 and the device controller. Is also possible.

The above-described embodiments merely show one aspect of the present invention, and can be arbitrarily modified and applied within the scope of the present invention.
For example, in the above-described embodiment, the processing control device 10 has the employee ID-detection ID correspondence database constituting the correspondence relationship storage unit. However, each communication control device 8 includes a correspondence relationship storage unit, The device 10 may be configured to transmit the detection ID and corresponding information (time stamp, device ID, etc.) only when a detection ID that actually exists is detected.
Moreover, although the case where this invention was applied to the in-house management system 1 was illustrated in embodiment mentioned above, it is not restricted to this, As a controlled apparatus which is provided in the entrance of a building and is a building incidental facility for every tenant in a building It is also possible to configure such that air conditioner control (operation, stop, etc.), lighting device control, and elevator control are performed.
In addition, it is applied to a system that detects the passage of an article through a passage gate, an ID is assigned to each article type, and a manufacturing apparatus or a processing apparatus (controlled apparatus) used for each article type is selectively used. It is also possible to configure the product to be manufactured in the same process.
