Description

  The present invention relates to a system for managing entry / exit of a plurality of persons, and more particularly to a technique for improving the efficiency of memory use for recording an entry / exit history.

Conventionally, an entrance / exit management system has been provided so that the door can be opened only when it is confirmed that the person has been permitted to enter the room.
For example, an electric lock and a card reader are provided on a door, and a person who wants to enter a room passes an authentication card through the card reader, and when authenticated, the electric lock is unlocked and placed in a room.
Such entrance / exit management systems include various systems in which doors are connected by a network and authentication is centrally performed by a single authentication device, and management devices are placed in each predetermined area to manage doors in the area. Such a system is considered (see Patent Document 1).

Furthermore, there is a system that records not only opening / closing doors based on the authentication result but also the authentication result and entry / exit history information such as information for identifying the person who entered the room.
Normally, the entry / exit history information is stored in the gate management device that manages the door, and it is possible to know when and who has entered the room, thereby contributing to security management.
JP 2004-84278 A

However, when there are a plurality of doors in the facility, there is usually a variation in the number of persons passing through each door. Also, the number of people passing through the door varies depending on the time of day.
In addition, there is of course a limit to the memory installed in the gate management device of each door. Normally, when the memory is full, the recorded information is old and the new information is overwritten. Go.

Therefore, a gate management device in which only recent information is recorded and a gate device that stores a small amount of old information coexist, and it is difficult to say that the memory is effectively used.
Therefore, an object of the present invention is to provide a gate management system that can effectively use a limited memory of a gate management device that manages a door in a facility.

  In order to solve the above problems, a gate management system of the present invention is a gate management system including a plurality of gate management devices connected to each other so as to communicate with each other, and the gate management device passes through a gate of an object. A passage information creation means for creating passage information that is information relating to passage each time it is detected, a storage means for storing the passage information, and a device specifying means for specifying one device among the gate management devices And, if the gate management device specified by the device specifying means is its own device, one of the passage information created by the passage information creation means and the passage information received from another gate management device One is stored in the storage means, and if the gate management device specified by the device specification means is another gate management device, the passage information created by the passage information creation means And a controlling means for transmitting a broadcast to the other gate management apparatus.

  Further, the gate management device of the present invention detects passage of an object through a gate, and at each detection, passage information creation means for creating passage information that is information related to passage, transmission means for transmitting passage information to the outside, A storage unit for storing passage information; a determination unit that determines whether the passage information created by the passage information creation unit is stored by the own device or another device; and the determined device is the own device. If there is, the passage information created by the passage information creation means is stored in the storage means, and if it is another device, the passage information created by the passage information creation means is transmitted by the transmission means. And a control means.

  The gate management system and the gate management device according to the present invention have the above-described configuration, so that information about something passing through the door managed by each gate management device is recorded by the own device or another device. As a result, it is possible to record a new history without overwriting the entry / exit history by overwriting as much as possible. That is, the memory installed in the apparatus can be used effectively.

For example, the memory of a gate management device that manages a door with a large number of employees passing through is immediately full and no old history remains, but the gate management device that manages a door with a small number of employees passing through is old. It can happen that it remains in the history and the memory is free, but this can be eliminated.
That is, according to the present invention, all the devices hold the entrance / exit information equally regardless of the door passing frequency managed by the gate management device, and the use efficiency of the memory is improved.

Accordingly, it is sufficient to consider the memory capacity of the entire system, and necessary information can be recorded without adding a memory of a specific gate management device.
Further, the device specifying unit may be configured such that when the storage unit of any one of the plurality of gate management devices stores a predetermined number of pieces of passage information, the gate management device is a device other than the gate management device. The gate management device transmits specific information for specifying a gate management device for which passage information is to be stored thereafter, and the device specifying means of the gate management device other than the gate management device performs a gate operation based on the received specific information. The management device may be specified.

As a result, if a predetermined number of pieces of passage information are recorded, it is possible to change the recording destination device, so that the memory can be used evenly.
In addition, when the storage unit of any one of the plurality of gate management devices stores passage information for a predetermined time, the gate management device is connected to a gate management device other than the gate management device. Thereafter, specifying information for specifying a gate management device to store the passage information is transmitted, and the device specifying means of the gate management device other than the gate management device specifies the gate management device based on the received specifying information. It is good also as performing.

As a result, if the passage information is recorded for a predetermined time, it is possible to change the recording destination device. Therefore, the memory is used evenly by considering the time zone and the door where the passage information frequently occurs. Will be able to.
For example, an apparatus having a large memory capacity is allocated as a recording destination apparatus in a time zone in which many employees pass.

  In addition, when the storage unit of any one of the plurality of gate management devices stores passage information of a predetermined capacity, the gate management device is connected to a gate management device other than the gate management device. Specific information for specifying the gate management device to store the passage information is transmitted, and the device specifying means of the gate management device other than the gate management device determines whether the free space of the storage means is based on the received specific information. The largest gate management device may be specified.

As a result, when a predetermined amount of passage information is recorded, the recording destination device can be changed, and a device having a large memory capacity can be used as the recording destination device, so that the memory can be used evenly. It becomes like this. In addition, the entire system has the advantage that the memory can be used to the maximum and more history can be recorded.
Since the gate management apparatus having the memory with the largest free capacity becomes the recording destination apparatus, the free capacity of the memory is equalized with time, and it is possible to easily cope with changes in the system configuration.

  In other words, even when disconnecting due to capacity change, device addition, failure, etc., the conditions for changing the recording destination device, such as the order of the recording device, etc. Even without re-doing, it is possible to automatically change the recording destination and effectively use the memory.

<Embodiment 1>
<Overview>
The gate management system according to the present invention is a system in which gate management devices that manage doors are connected to each other via a network so that data can be exchanged, and entry / exit history information is recorded with each other.

In other words, all the door entry / exit history information managed by the device itself is not recorded by the device itself, but is recorded by another gate management device based on a predetermined rule. By recording the history information, the memory utilization efficiency is improved as a whole system.
Hereinafter, an example of the gate management system according to the present invention will be described.

This example is an entry / exit management system of a company. When entering and leaving, employees use a card reader with a numeric keypad next to the door to read the card with the employee ID recorded, and their own personal identification number. To open the door.
Also, the method for recording the entrance / exit information is to specify a certain gate management device as a recording destination device, and after recording certain information, the recording destination device is sequentially changed. The recording destination device records the entrance / exit information of all doors. The recording destination devices are changed sequentially, and the memory of each device is used evenly.

<Data>
Hereinafter, main data used by the gate management system according to the present invention will be described with reference to FIGS.
2 is a diagram illustrating an example of data stored in the connection information storage unit 1200, FIG. 2A is a diagram illustrating an example of contents of the connection information 1210, and FIG. 2B is a recording destination. It is a figure which shows the example of the content of the information 1220.

First, the connection information 1210 shown in FIG. 2A includes a gate management device ID 1211, an address 1212, and a data count 1213. The same connection information 1210 is stored in each connection information storage unit 1200 for all gate management apparatuses.
The gate management device ID 1211 is an identifier of the gate management device that constitutes the system.
The address 1212 is an address such as an IP address of the gate management device represented by the gate management device ID 1211 for communication.

The number of data 1213 represents the number of entry / exit information 1420 recorded by the gate management device represented by the gate management device ID 1211.
In the present embodiment, the recording destination is sequentially changed in the order indicated by the gate management device ID 1211 of the connection information 1210, and the recording destination device stores the number of pieces of entry / exit information represented by the number of data 1213. Once stored, the recording destination is changed.

For example, a gate management device whose gate management device ID 1211 is represented by “G100” has an address of “addr_100”, and the number of data 1213 “8” entry / exit information is turned around as a recording destination. To record.
The number of data 1213 may be determined according to the amount of memory installed in the gate management apparatus, or may be set to the same number.

Next, the recording destination information 1220 shown in FIG. 2B is composed of the own device ID 1221, the recording destination device ID 1222, and the number of gate management devices 1223. This recording destination information 1220 is stored in each connection information storage unit 1200 for all gate management devices except for the own device ID 1221.
The own device ID 1221 is a gate management device ID representing the own device, and is the corresponding gate management device ID 1211. Therefore, the content of the own device ID 1221 differs for each gate management device.

The recording destination device ID 1222 is a gate management device ID 1211 representing a gate management device that records the current entry / exit information. This content is updated by the recording destination device specifying unit (1600, etc.) of each device.
The number of gate management devices 1223 represents the number of gate management devices constituting this system. In this embodiment, the gate management device ID 1211 of the connection information 1210 is valid for the number of gate management devices 1223 from the first gate management device ID 1211.

Next, FIG. 3 is a diagram showing an example of the contents of the authentication information 1310.
This authentication information 1310 is stored in the authentication information storage unit 1300 and basically has the same contents in all gate management apparatuses. However, if there is an employee whose entry / exit is not permitted by the door, there may be information to that effect. In the present embodiment, it is assumed that the contents are the same for convenience of explanation.
The authentication information 1310 includes an employee ID 1311 and a personal identification number 1312.

The employee ID 1311 is an employee identifier.
The personal identification number 1312 is a personal identification number unique to the employee and corresponds to the employee ID 1311. When the correspondence between the employee ID 1311 read from the card by the entry reader or the like and the personal identification number 1312 input by the numeric keypad is obtained, it is determined that the authentication has been made.
FIG. 4 is information related to the entry / exit history, FIG. 4 (a) is a diagram showing an example of the contents of entry / exit information 1420, and FIG. 4 (b) is a diagram showing an example of the contents of entry / exit history information 1410. .

This entry / exit history information 1410 is stored in the entry / exit history storage unit 1400, and the contents thereof are different for each gate management apparatus. The entry / exit history information 1410 includes a plurality of entry / exit information 1420.
One entry / exit information 1420 in FIG. 4A is created and transmitted to the recording destination apparatus in this format when one door is attempted to pass through once.

The entrance / exit information 1420 includes a door 1411, a date and time 1412, an employee ID 1413, and a pass / fail result 1414.
The door 1411 indicates the door that the employee has attempted to pass and whether the employee has attempted to enter or leave the room. For example, the door 1411 “G100A-enter” in the first entry / exit information 1420 indicates that the “entry reader” of the door “G100A” has been operated.

“G100” indicates that the gate is managed by the gate management device represented by the gate management device ID 1211 “G100”, “A” is an identifier of the door, and “enter” is the entrance reader 1012. “Retreat” indicates that the room reader 1013 has been operated.
The date and time 1412 represents the time when the employee operated the entrance reader 1012 or the exit reader 1013.

The employee ID 1413 represents the employee ID of the employee who is going to enter or leave the room.
The passage permission / inhibition result 1414 indicates whether the passage is actually performed, that is, whether the authentication is successful. “OK” indicates a case where the authentication succeeds and the employee passes through the door, and “NG” indicates a case where the authentication fails.
The entry / exit history information 1410 in FIG. 4B is obtained by accumulating entry / exit information 1420 and has the same configuration as the entry / exit information 1420.

<Operation>
Hereinafter, the operation of the above-described gate management system will be described with reference to FIG.
FIG. 5 is a flowchart showing processing of each gate management apparatus when the recording destination apparatus is the gate management apparatus 2000.
In this figure, two processes will be described.

One is a process when an employee passes through a door managed by a certain gate management device, and the other gate management device records the entrance / exit information, and the second is a case where the recording destination device is changed. It is processing.
As a premise, first, how to determine the recording destination gate management apparatus will be described.
<How to determine the gate management device for recording>
It is assumed that the connection information 1210 stored in the connection information storage unit 1200 of each gate management device is determined in order. For example, the device with the gate management device ID 1211 of “G100” is first, and the device of “G200” is next.

The timing for changing to the next device is when the room entry / exit information 1420 corresponding to the number of data 1213 is stored. For example, if the device of “G100” is the recording destination device, when the eight entrance / exit information 1420 is stored, the other gate management devices are notified that the recording destination is to be changed. The changed recording destination device is the “G200” device.
After making this change to the last device, repeat from the beginning. The number of devices in which this repetition is performed is the value of the number of gate management devices 1223. For example, if “8”, the eight devices from the top become the recording destination devices in order.

As new devices are added and removed, this number will change accordingly.
<Processing when other gate management devices record entry / exit information>
First, as a first process, a process when an employee passes through a door managed by the gate management apparatus 1000 and the entrance / exit information 1420 is recorded by the gate management apparatus 2000 will be described.
The gate management device ID 1211 of the gate management device 1000 is “G100”, and the gate management device ID 1211 of the gate management device 2000 is “G200”.

In addition, since each gate management device has the same function, the same flowchart is shown, but the route executed on the side that transmits / receives the entry / exit information, the side that receives and stores the information, and the route executed on each side are indicated by bold lines (FIG. 6). The same).
First, an employee tries to pass through a door 1010 that is managed by the gate management apparatus 1000 and whose door identifier is “A”. Pass your ID card through the card reader of the entrance reader 1012 of the door 1010, and enter your password using the numeric keypad.

The entrance reader 1012 reads the employee ID 1311 from the passed card, detects the depression of the numeric keypad, acquires the personal identification number 1312, and passes it to the control unit 1100.
The control unit 1100 passes the received employee ID 1311 and personal identification number 1312 to the authentication unit 1700 and requests authentication. At this time, the current date and time are obtained from a built-in timer (not shown) and stored in a work area (not shown).

The authentication unit 1700 requested to authenticate refers to the authentication information 1310 stored in the authentication information storage unit 1300, and determines whether or not the passed employee ID 1311 and personal identification number 1312 are paired (step). S100). The determination result is returned to the control unit 1100.
The control unit 1100 that has received the determination result issues an instruction to unlock the electric lock 1011 if it is paired, that is, if the authentication is successful, and if the authentication is not successful, the electric lock 1011 is issued. Do not give instructions.

For example, if the employee ID 1311 is “000000001” and the personal identification number 1312 is “1234”, it is determined that the authentication is successful.
Thereafter, the control unit 1100 passes the employee ID, the determination result, the door identifier, and the date and time stored in the work area to the entry / exit history creation unit 1800, and requests creation of the entry / exit information 1420.

Upon receipt of the request, the entry / exit history creation unit 1800 creates entry / exit information 1420 (step S110).
For example, the door 1411 is “G100A-On”, the date and time 1412 is “2005/09/14 11:40”, the employee ID 1413 is “000000001”, and the pass / fail result 1414 is “OK”.
The control unit 1100 that requested the entry / exit history creation unit 1800 to create the entry / exit information 1420 inquires the recording destination device identification unit 1600 about the recording destination.

Upon receiving the inquiry, the recording destination device specifying unit 1600 refers to the recording destination information 1220 stored in the connection information storage unit 1200 and reads out the own device ID 1221 and the recording destination device ID 1222.
The recording destination device identification unit 1600 returns to the control unit 1100 the recording destination device ID 1221 and the recording destination device ID 1222 that are the same as the recording destination, and if not, the address 1212 of the recording destination device ID 1222 is returned to the control unit 1100 (step S120). ).

  If the recording destination is the own device (step S120: own device), the control unit 1100 that received the recording destination notifies the entry / exit history creating unit 1800 to that effect and stores the created entry / exit information 1420 in the entry / exit history record memory. Instructed to be added to and stored in the entry / exit history information 1410 of the unit 1400. The entry / exit history creation unit 1800 adds the entry / exit history information 1410 to the entry / exit history information 1410 and stores it (step S130).

If the recording destination is another device (step S120: other device), the created entry / exit information 1420 is received from the entry / exit history creation unit 1800 and transferred to the communication unit 1500 together with the address 1212 received from the recording destination device identification unit 1600. Request transmission.
For example, when the own device ID 1221 is “G100” and the recording destination device ID 1222 is “G200”, it is determined as another device, and the address 1212 “addr_200” corresponding to the gate management device ID 1211 corresponding to “G200” is used as the address. Will be passed to.

The communication unit 1500 that has received the transmission request transmits the entry / exit information 1420 to the address 1212 (step S140).
The transmitted entry / exit information 1420 is received by the communication unit 2500 of the gate management apparatus 2000 via the network 10 (step S141).
The communication unit 2500 of the gate management apparatus 2000 that is the recording destination device passes the received entry / exit information 1420 to the control unit 2100.

The control unit 2100 that has received the entry / exit information 1420 from the communication unit 2500 passes the received entry / exit information 1420 to the entry / exit history creation unit 2800 and issues an instruction to store it.
The entry / exit history creation unit 2800 that has received the instruction stores the entry / exit history storage unit 2400 in the entry / exit history storage unit 2400 (step S230).
For example, in the entry / exit history information 1410 of the entry / exit history storage unit 2400, the door 1411 is “G100A-enter”, the date and time 1412 is “2005/09/14 11:40”, the employee ID 1413 is “000000001”, and the pass / fail result result. The entrance / exit information 1420 with 1414 “OK” is recorded.

  When the employee tries to pass through the door managed by the gate management apparatus 2000 as the recording destination, the same operation as that of the gate management apparatus 1000 is performed. That is, the employee is authenticated (step S200), entrance / exit information 1420 is created (step S210), the recording device is determined to be the own device (step S220), and the entrance / exit information 1420 is stored in the entrance / exit history storage unit 2400. (Step S230).

When the gate management device 2000 is no longer the recording destination device, the entrance / exit information 1420 is transmitted to the recording destination device (step S240).
<Process when changing the recording destination device>
Next, a case where the recording destination apparatus is changed will be described.
It is assumed that the control unit 2100 inquires of the recording destination device specifying unit 2600 in advance about the number of records of the entrance / exit information 1420 of the own device and stores it. For example, in the initial process, the recording destination device specifying unit 2600 refers to the connection information 1210 in the connection information storage unit 2200 and notifies the control unit of the number of data 1213 corresponding to the gate management device ID 1211 of the own device ID 1221.

The control unit 2100 of the gate management device 2000 that is the recording destination device stores the entrance / exit information 1420 of the door managed by the own device and the entrance / exit information 1420 sent from another device to the entrance / exit history creation unit 2800. It is stored in the entrance / exit history storage unit 2400 (step S230).
The control unit 2100 counts the number of recorded room entry / exit information 1420 from the time when it becomes the recording destination device this time, and when it reaches the number of data 1213 (step S250: Y), it notifies that the recording destination is to be changed. Is sent to all the other gate management devices.

Receiving the instruction, the communication unit 2500 transmits a notification to the effect that the recording destination is changed to all devices.
In addition, the control unit 2100 requests the recording destination device specifying unit 2600 to change the recording destination (step S161).
Upon receiving the request, the recording destination device specifying unit 2600 updates the recording destination device ID 1222 of the recording destination information 1220 stored in the connection information storage unit 2200 (step S260). That is, if the current recording destination device ID 1222 is “G100”, the gate management device ID 1211 “G200” next to the gate management device ID 1211 of the connection information 1210 is “G100” as the new recording destination device ID 1222.

Note that the control unit 2100 records the entrance / exit information 1420 sent when the device itself is not the recording destination device, but does not count.
<Modification>
In the first embodiment, in the method of determining the recording destination gate management device, the timing for changing to the next device is when the entry / exit information 1420 corresponding to the number of data 1213 is stored. (See <How to determine the recording destination gate management device> above.)
This modification is different in that time is used instead of the number of recorded data.

That is, if the entry / exit information 1420 is recorded for a predetermined time, it is updated to the next recording destination.
<Data>
Regarding the data used in this modification, only the connection information 1210 is different from that of the first embodiment.
FIG. 11 shows an example of the contents of the connection information 9210 of this modification.

The difference between the connection information 9210 and the connection information 1210 of the first embodiment is that a period 9211 is stored instead of the number of data 1213.
For example, when the device whose gate management device ID 1211 is “G100” is the recording destination, the entry / exit information 1420 from the own device and other devices is recorded for the period 9211 “20”.

<Operation>
The difference in operation between this modification and the first embodiment is steps S250 and S150 in the flowchart of FIG.
In the first embodiment, the control unit 2100 counts the number of recorded entry / exit information 1420, but instead counts time. The time is obtained from a built-in timer.

The control unit 2100 starts counting time from the time of becoming the recording destination device, and when the period 9211 of its own device has elapsed, the communication unit 2500 sends a notification to change the recording destination to all other gate management devices. For example, when the device whose gate management device ID 1211 is represented by “G200” is the recording destination, when the period 9211 “60” has elapsed, a notification to change the recording destination is sent.

In this case, in addition to efficient use of the memory, for example, a device with a large capacity of the entry / exit history storage unit is used as a recording destination device or entry / exit is concentrated in a time zone where employees enter / exit in time. By using the door as a recording destination device, the amount of data flowing on the network can be minimized, and employees can enter and leave the room smoothly.
<Embodiment 2>
In the first embodiment, all the entrance / exit information 1420 sent from other gate management devices is recorded even if the device is not the recording destination device due to the update instruction of the recording destination device.

This is because the entry / exit information 1420 may be received immediately after the recording destination device is updated from its own device to another device.
For example, the information reception timing is delayed due to some reason such as the entrance / exit of a plurality of people or the network congestion, almost simultaneously with the change of the recording destination device.
In the first embodiment, by recording all received entry / exit information, it is possible to eliminate omission of recording even when a previous recording destination device that is not the recording destination device has received the current information. ing.

In this embodiment, the entry / exit information 1420 is recorded in the correct recording destination apparatus even in such a case.
In other words, when the device that issued the notification that the recording destination device is to be changed, that is, the previous recording destination device has received the entry / exit device, it is recorded in the correct recording destination device by transferring it to the current recording destination device. .

The data used in the present embodiment is the same as that used in the first embodiment.
Hereinafter, the operation of the present embodiment will be described.
<Operation>
FIG. 6 is a flowchart showing the processing of the gate management apparatus which is the recording destination apparatus.
The difference from the flowchart of the first embodiment shown in FIG. 5 is that the entrance / exit information transmitted from another gate management apparatus is not necessarily recorded in the own apparatus.

That is, when entering / leaving information is received from another gate management apparatus, if the own apparatus is no longer the recording destination apparatus, it is transferred to the current recording destination apparatus.
The operation of the device that transmits the entrance / exit information 1420 and the operation of the current recording destination device are the same as those of the first embodiment.
Therefore, here, only the differences between the operation of the device that transmits the entry / exit information 1420 and the operation of the previous recording destination device from the flowchart of FIG. 5 will be described.

The communication unit 1500 on the transmitting side transmits the entry / exit information 1420 to the address 1212 (step S140).
The transmitted entry / exit information 1420 is received by the communication unit 2500 of the gate management apparatus 2000 via the network 10 (step S300).
The control unit 2100 that has received the entry / exit information 1420 via the communication unit 2500 first inquires of the recording destination device specifying unit 2600 whether or not the own device is the recording destination device (step S310).

In response to the inquiry, the recording destination specifying unit 2600 indicates that the own device ID 1221 and the recording destination device ID 1222 are the same, and that the own device is not the recording destination device. And the address 1212 of the recording destination device ID 1222 are notified (see FIG. 2).
Receiving the notification that the device itself is not the recording destination device (step S310: other device), the controller 2100 transmits the entry / exit information 1420 to the notified address. That is, the communication unit 2500 is instructed (step S320).

Further, the control unit 2100 that has received the notification that the own device is the recording destination device (step S310: own device) passes the received entry / exit information 1420 to the entry / exit history creation unit 2800 and gives an instruction to store it. put out.
In the case of this embodiment, there is an advantage that the entry / exit information is recorded in the original recording destination device, and the memory can be effectively used as scheduled.

<Embodiment 3>
In the first embodiment, the recording destination device is one device, but in this embodiment, there are two devices.
That is, it has a backup function. Therefore, there is an advantage that the possibility that the entrance / exit information is lost when the gate management device breaks down is reduced.

<Data>
Regarding data used in the present embodiment, only the recording destination information 7220 is different from that in the first embodiment.
FIG. 8 shows an example of the contents of the recording destination information 7220 of this embodiment.
The difference between the recording destination information 7220 and the recording destination information 1220 of the first embodiment is that it has two recording destination device IDs. Recording destination device ID-1 (7221) and recording destination device ID-2 (7222).

<Operation>
The difference in operation between the present embodiment and the first embodiment is the operation of the device on the side of the gate management device (other than the recording destination device) 1000 in the flowchart of FIG.
The operation of the gate management apparatus 1000 will be described with reference to FIG.
Steps S120 and S140 of the flow of the gate management apparatus 1000 in FIG. 5 are different. Here, only different points will be described.

The employee attempts to pass through the door, and the control unit 1100 creates the entry / exit information 1420 from the entry / exit history creation unit 1800 and inquires the recording destination device identification unit 1600 about the recording destination.
Receiving the inquiry about the recording destination from the control unit 1100, the recording destination device specifying unit 1600 refers to the recording destination information 7220 stored in the connection information storage unit 1200, and the own device ID 1221 and the recording destination device ID-1 (7221). ) And recording destination device ID-2 (7222).

  If the read-out device ID 1221 and the recording-destination device ID-1 or the recording-destination device ID-2 are the same as the recording destination, the recording-destination device specifying unit 1600 indicates that the recording destination device ID- 1 or the address 1212 of the recording destination apparatus ID-2 is returned to the control unit 1100. If they are different, the fact and the addresses 1212 of the recording destination device ID-1 and the recording destination device ID-2 are returned to the control unit 1100 (step S400).

If the control unit 1100 that has received the recording destination includes the own device in the recording destination (step S400: self-contained device), it notifies the entry / exit history creation unit 1800 to that effect and enters the entry / exit information 1420 into the entry / exit history. It memorize | stores in the memory | storage part 1400 (step S130).
At the same time, the created entry / exit information 1420 is received from the entry / exit history creation unit 1800, and is transferred to the communication unit 1500 together with the address 1212 other than the own device received from the recording destination device specifying unit 1600 to request transmission (step S410). .

On the other hand, if the recording destination is only the other device (step S400: only the other device), the created entry / exit information 1420 is received from the entry / exit history creation unit 1800, and together with the two addresses 1212 received from the recording destination device specifying unit 1600. Then, the data is transferred to the communication unit 1500 to request transmission (steps S420 and S430).
For example, when the own device ID 1221 is “G100”, the recording destination device ID-1 (7221) is “G200”, and the recording destination device ID-2 (7222) is “G200”, it is determined that only the other device is present, and gate management is performed. Two addresses corresponding to the device ID 1211 corresponding to “G200” and “G300” are passed to the communication unit 1500 as addresses.

Upon receiving the transmission request, the communication unit 1500 transmits the entry / exit information 1420 to the address 1212.
<Embodiment 4>
In the first embodiment, in the method of determining the recording destination gate management device, the timing for changing to the next device is when the entry / exit information 1420 corresponding to the number of data 1213 is stored. (See <How to determine the recording destination gate management device> above.)
This embodiment is different in that the next recording destination device is determined not by the number of recorded data but by the free space of the memory of the gate management device.

<Data>
Regarding the data used in this embodiment, only the connection information 1210 is different from that in the first embodiment.
FIG. 10 shows an example of the contents of the connection information 8210 of this embodiment.
The difference between the connection information 8210 and the connection information 1210 of the first embodiment is that an empty capacity 2211 is stored instead of the number of data 1213.

<Operation>
The difference in operation between the present embodiment and the first embodiment is the operation on the gate management apparatus (other than the recording destination apparatus) 2000 side in the flowchart of FIG.
The operation of the gate management apparatus 2000 will be described with reference to FIG.
Steps S250 and S260 of the flow of the gate management apparatus 2000 in FIG. 5 are different. Here, only step S500, step S510, and step S520 corresponding to them will be described.

The control unit 2100 of the gate management device 2000, which is the recording destination device, enters the entrance / exit information 1420 of the door managed by the own device and the entrance / exit information 1420 sent from another device into the entrance / exit history creation unit 2800. It is stored in the leaving history storage unit 2400 (step S230).
At the same time, the control unit 2100 stores the total capacity number of the recorded entry / exit information 1420 from the time when it becomes the recording destination device this time, and updates the stored total amount (step S500).

When the current total capacity stored in the control unit 2100 reaches a predetermined capacity (step S510: a predetermined value or more), a notification that the free capacity 8211 of the apparatus and the recording destination apparatus are to be changed is notified. The communication unit 2500 is instructed to send to the gate management device (step S520, step S521).
At the same time, it instructs the recording destination device specifying unit 2600 to update the free space of the own device and the recording destination device. Receiving the instruction, the recording destination device specifying unit 2600 updates the free capacity 8211 corresponding to the own device in the connection information 8210 and the recording destination device ID 1222.

As a recording destination device, a device having the largest free capacity at that time is assumed.
Further, the other device that has received the message updates the free space of the current recording destination device in the connection information 8210 in the own device, and sets the recording destination device as the next device.
On the other hand, when the prescribed capacity is not reached (step S510: less than the prescribed value), the entrance / exit information is subsequently stored.
