A lock control device 20 controls the lock 30, the middle card reader 28, the outer card reader 29, the final push button 27, and the like. FIG. 7 is a transition diagram of the lock state of the entry / exit management system. The lock state of the system includes an unlocked state, a temporary locked state, and a main locked state. In the unlocked state, the door is opened for a certain period of time so that a person can enter and exit, and after the passage of the person is completed, the state returns to the temporarily locked state after a certain period of time. In the temporary lock state, the lock control device shifts the lock to the unlocked state if there is a card input by a qualified person with any of the card readers.

When there is an input from the final push button 27 in the temporarily locked state , the lock control device shifts the lock to the fully locked state.
When the privilege card is read by the card reader from the locked state, the state is unlocked. The privilege card is held by the security guard, and the access control system opens all doors in any state when reading this card.

[0006] An ordinary person has his / her own ID card, and the ID card describes the qualifications of traffic, and the time zone and the range of traffic that can be used by the qualifications are defined. FIG. 8 is a configuration diagram of a conventional entry / exit management system. In the figure, items having the same reference numerals as those in FIG. 5 are the same. More detailed configurations of the host device 10 and the lock control device 20 will be described. The host device 10 controls a plurality of lock control devices 20, and has a communication control unit 13, a user list file 14, and a user qualification determination unit 15. A communication control unit 13 transmits and receives information to and from the communication processing units 22 of the plurality of lock control devices 20.

Reference numeral 14 denotes a user list file, which is a list of users who use the entry / exit management system, and records a time zone and a range of rooms in which the user can pass according to the name of the user. . A user qualification determination unit 15 determines the qualification of a person who passes through the door with reference to the user list file 14.

The lock control device 20 includes a microprocessor (hereinafter abbreviated as MPU) 21, a communication processing unit 22, a middle card reader control unit 23, an outside card reader control unit 24, a lock control unit 25,
The final push button 27 is included. 21 is an MPU,
This controls the lock control device 20. A communication processing unit 22 communicates with the host device 10. Reference numeral 23 denotes a middle card reader control unit which receives data read from a middle card reader 28 provided inside the room, and
This is sent to PU21. 24 is an outside card reader control unit, which is an outside card reader provided outside the room
The data read from 29 is sent to the MPU 21. Reference numeral 25 denotes a lock control unit which controls a lock 30 for controlling opening and closing of the door 31. 27 is a final push button,
When the push button is pressed, the lock control device 20 shifts the system to the fully locked state.

Reference numeral 28 denotes a middle card reader, which is a card reader provided inside the room. Reference numeral 29 denotes an outside card reader, which is a card reader provided outside the room. Reference numeral 30 denotes a lock, which controls a door 31 that enters and exits the room.

FIG. 9 is a diagram for explaining the interface between the lock control unit and the lock. A relay drive current for driving the lock 30 of the door 31 is supplied from the lock control unit 25 of the lock control device 20 to the door 31, and a contact signal for notifying the state of the lock 30 of the door 31 is transmitted to the lock 30 of the door 31. Transmitted to the lock control unit 25, the lock control unit 25 can detect whether the state of the lock 30 on the door is the unlocked state or the locked state.

In such an entry / exit management system, a person who wants to enter inside through the door 31 of the room has his outer card reader 29 read his / her ID card. The MPU 21 of the lock control device 20 transmits the ID card information from the outer card reader control unit to the host device 10 via the communication processing unit 22. This information is received by the communication control unit 13 of the host device 10, and the user qualification determination unit
Pass to 15. The user qualification judgment unit 15 is a user list file 14
, The possible time zone and the range of traffic corresponding to the ID card information are checked to determine whether the door can be passed. The determination result is transmitted to the MPU 21 via the communication control unit 13 and the communication processing unit 22. If there is no qualification, the MPU 21 keeps the lock control unit 25 in the temporarily locked state and prevents the door 31 from being opened. . If the driver is qualified to pass, the MPU 21 drives the lock controller 25 to put the lock 30 in the unlocked state so that the door 31 is opened so that the driver can pass. When the vehicle is passed, the MPU 21 reports that the vehicle has been passed to the host device 10, and the usage recording unit 11 records the user record file 12 for each door of the room in the host device 10.

In the conventional entry / exit management system, the lock control device is independent for each room, and the state control of the lock control device is the same in the host device. That is, even if one lock control device shifts from the temporary lock state to the main lock state, the state of the other lock control devices does not affect it.

Therefore, in such a system, 4
On the floor with one room (one tablet per room control device), it was necessary to perform the final locking operation (depressing the final push button 27) for each of the four rooms when finally leaving the room. While independent operation is possible for each room, there is a problem in operations requiring high security, such as the final exit, that the locking operation is forgotten and returned to the temporary locked state.

[0014]

In the conventional entrance / exit management system, the main locking operation is performed for each room, and the room is not associated with another room. However, there is a problem that the device is left in a temporarily locked state.

In view of the foregoing, it is an object of the present invention to provide a means for detecting that the main locking operation has been forgotten and performing the main locking operation in a room where the main locking operation has been forgotten.

[0016]

The above object is achieved by an entry / exit management system configured as described below.

[Function] The user record file 12 records the number of people who enter and exit through the door of each room.
The use recording unit 11 is provided so as to record each lock control device and manage the entire lock control device in groups.

That is, all the persons in the room belonging to the group return, and at this time, the main locking operation (depression of the final push button 27)
The doors of the rooms belonging to the group are fully locked. Therefore, the group lock instructing unit 51 provided in the higher-level device 10 checks the user record file 12 to confirm that there is no occupant in the room belonging to the group, and then controls all the locks belonging to the one group. The device 20 is instructed to be in the final locked state. Thus, any lock control device

By confirming that there is no occupant in the room, and setting the locks of the group to the fully locked state, it is possible to avoid the temporary locked state due to forgetting the actual locking operation.

[0020]

FIG. 2 is a block diagram of an entry / exit management system according to an embodiment of the present invention. In the drawing, reference numeral 11 denotes a use recording unit, which is information on persons who pass through the door 31 from the card reader by the lock control device 20 (particularly, the difference between the number of persons entering the room and the number of persons leaving the room, that is, being in the room Number of users) user results file 12
It is recorded in. Reference numeral 12 denotes a user record file, and the doors of all the lock control devices 20 managed by the host device 10.
It holds 31 achievements.

Upon receiving the user record data transmitted from the card reader, the usage recording unit 11 determines whether the transmission source is the middle card reader control unit 23 or the outside card reader control unit 24, and If it is the side card reader control unit 23, it is counted as a leaving person, and if it is the outside card reader control unit 24, it is counted as a entering person.

The result recorded in the user result file 12 is updated with this value. Reference numeral 51 denotes a group lock instructing unit, which determines from the user record file 12 that there is no person staying in all the rooms belonging to the one group, and controls all the locks belonging to the one group. This is for instructing the device 20 to make the lock state. In addition, items having the same reference numerals as those in FIG. 8 are the same.

FIG. 4 is a diagram showing the structure of a user record file according to the embodiment of the present invention. The lock control information indicating whether the lock state of each lock control device is an unlocked state, a temporary lock state, or a permanent lock state, the number of people N _i entering the room, the number of people N _j leaving the room, and the group number are as follows. It is recorded, and the number of persons is added and recorded each time there is a report on the result of passing the door from each lock control device.

This embodiment is different from the conventional one in the operation when the last push button of the group is operated. FIG. 3 is a flowchart of the group lock instruction unit according to the embodiment of the present invention, which will be described with reference to the drawing.

In step 90, the group lock instructing section 51 of the host device 10 sends a final exit operation (final push button) from a lock control device 20.
27 press). In step 91, the group lock instruction unit 51 sequentially searches the records of the user record file 12 for the state of the other lock control devices in the same group, and determines whether there is a resident person in a room under the control of the other lock control device, and The lock control device checks whether the final exit operation has been performed (that is, whether the door has been fully locked).

If it is determined in step 92 that the final exit operation has been performed in all the lock control devices and that there is no occupant in the room by checking the user record file 12,
Proceed to 93. If no, go to step 94.

In step 93, an instruction is issued from the group lock instructing section 51 of the host device 10 to perform the actual locking for all the lock control devices. As a result, all the lock control devices that have been temporarily locked are in the fully locked state.

In step 94, since there is still a room in which a resident stays, an instruction is issued from the group lock instructing section 51 so that only the lock control device for which the final exit operation has been performed is in the main lock state.
FIG. 5 is a flowchart of the usage recording unit according to the embodiment of the present invention. The use recording unit corrects and records the record of the user record file of FIG. 4 based on the notification of the record of the door passing from each lock control device and the notice of the final exit operation. The operation of the usage recording unit will be described below.

When the notification is received in step 95, it is determined which notification is to be made.
The process proceeds to step 96 in the case of the final exit notification to step 96. In step 96, the record of the state of the lock control device corresponding to the notification of the final exit operation is corrected from the temporarily locked state to the fully locked state, and the process ends.

In step 97, the middle card reader control unit 23
It is determined whether the user has entered the room or has left the room by looking at the notification from the outside or the notification from the outside card reader control unit 24. If the room has left, the process proceeds to step 98, and if the room has entered, the process proceeds to step 99.

In step 98, the number of occupants of the corresponding room is incremented by one, and the process ends. In step 99, the number of occupants in the corresponding room is decremented by one, and the process ends. In this way, the usage record is always updated.

Conventionally, even if the locking operation is performed by the lock control device at the last exit from the room, the status of the other lock control devices is not processed at all. In the present invention, when the lock operation is performed on the lock control device 20 at the time of the last exit, the host device 10 searches for another lock control device in the same group as the lock control device that received the notification, and enters the main lock state. If the transition condition is satisfied, this locking is instructed to the other lock control.

Thus, even if the final locking operation is forgotten, the final locking operation of the last person who leaves the group completes the full locking of all the rooms in the group. It is also possible to detect that there is no staying person in each room in the group and to perform the final locking of all the rooms in the group, thereby preventing the last person who left the room from forgetting to perform the final locking operation. .

[0034]

As is apparent from the above description, according to the present invention, in the system for centrally managing a plurality of rooms, the host device detects that the locking operation has been forgotten, and forgets the locking operation. There is a remarkable industrial effect of locking the room.

The purpose of the building management system is as follows:
In particular, security improvement. In the case of the present invention, the higher-level device centrally manages a plurality of rooms, and is particularly effective in the operation of the final exit operation that requires particularly high security among complicated operations.
