(Operation) According to the present invention, since the entry / exit management device is configured as described above, for example, when a person exits from the door provided with the control electric lock to the outside of the room, the non-control electric lock is used. If the lock is forgotten, the unlocked state is confirmed by the third lock / unlock confirmation unit of the uncontrolled electric lock, and the closed loop signal is cut off. Therefore, since the closed loop signal is not input to the first opening / closing confirmation section of the door gate terminal device, the first opening / closing confirmation section confirms that the lock has been forgotten. Warn the person.

(Embodiment) FIG. 1 is a configuration diagram of an entry / exit management device showing an embodiment of the present invention, and FIG. 3 is a flowchart showing a lock forgetting check by the door gate terminal device of FIG.

In FIG. 1, the entry / exit management device includes a room 11, a center device 12, a door gate terminal device 13, a control electric lock 14, and a non-control electric lock 15.

The center device 12 registers an ID card, outputs the data to the door gate terminal device 13 via the transmission line 16, and displays and records the entry and exit of the room.

The door gate terminal device 13 is installed near the door where the control electric lock 14 is provided, and includes a terminal body 13-1, a card reader 13
-2 and an indicator 13-3. Card reader 13−
Reference numeral 2 denotes an ID card for reading the ID card.
Numeral 3 is for displaying a lock forgetting.

The terminal body 13-1 is provided with a lock / unlock output unit 13a, a first lock / unlock confirmation unit 13b, and a first open / close confirmation unit (for example, a door open / close confirmation unit) 13c. The locking / unlocking output unit 13a is connected to a first locking / unlocking means (for example, a solenoid) 14a of the control electric lock 14, and controls the operation of the solenoid 14a. The lock / unlock confirmation unit 13b is connected to the second lock / unlock confirmation unit 14b of the control electric lock 14, from which a lock / unlock confirmation unit signal is output to the terminal body 13-1.

The door opening / closing confirmation unit 13c includes a second opening / closing confirmation unit (for example, a door opening / closing confirmation unit) 14c of the control electric lock 14 and a third locking / unlocking confirmation unit 15b of the non-control electric lock 15, and a third opening / closing confirmation unit. (For example, a door open / close confirming unit) 15c, thereby forming a loop-shaped forgetting prevention circuit 18 using a loop line 17 for transmitting a closed loop signal.

The non-control electric lock 15 is provided on a door different from the door on which the control electric lock 14 is provided, and is manually unlocked directly from the room by a second locking / unlocking means (for example, a solenoid) 15a. I have.

The operation for preventing forgetting to lock in the entry / exit management device configured as described above will be described with reference to the flowchart of FIG.

First, a person opens the room 11 through the door provided with the control electric lock 14.
You must leave outside. Leave the room with a card reader 13-
Insert the ID card into 2 and enter the ID code.

The ID code read by the card reader 13-2 is collated with the ID code registered in the terminal body 13-1. The registered ID code is transmitted from the center device 12 to the terminal body 13-1 and stored in advance.
If the ID code does not match as a result of verification,
Subsequent operations are rejected by 13-1.

When the ID codes match, the door opening / closing confirmation section 13c of the terminal body 13-1 checks whether or not the lock forgetting prevention circuit 18 is in a closed loop and a closed loop signal is being input. Here, if the exit person forgets to lock the non-control electric lock 15, the door open / close confirmation units 14c and 15c of the control electric lock 14 and the non-control electric lock 15 are closed (make).
The lock / unlock confirmation unit 15b of the non-control electric lock 15 enters the open (break) state, and the closed loop signal is interrupted.

Therefore, the lock forgetting prevention circuit 18 does not become a closed loop,
This is confirmed by the door opening / closing confirmation unit 13c of the terminal body 13-1.

As a result, the terminal body 13-1 detects that the user has forgotten to lock the non-control electric lock 15 or to close the door, and causes the indicator 13-3 to display a message to that effect.

On the other hand, when the non-control electric lock 15 is locked, the lock forgetting prevention circuit 18 becomes a closed loop and a closed loop signal is input to the door open / close confirmation unit 13c. It is confirmed. At this time, the terminal body 13-1 operates the locking / unlocking output unit 13a, and the control electric lock 1

As described above, in this embodiment, the person who left the room has the uncontrolled electric lock 15.
If the user forgets to lock the door or forgets to close the door, this is displayed on the indicator 13-3, and the control electric lock 14
Is not locked. Therefore, forgetting to lock the non-control electric lock 15 can be reliably prevented. In addition, the apparatus of the present embodiment can be installed at low cost, and since the locking and unlocking operations are almost the same as those in the related art, there is no risk of operating problems.

The present invention is not limited to the illustrated embodiment, and various modifications are possible, for example, the following modifications.

(A) The door provided with the control electric lock 14 and the non-control electric lock 15 indicates a door in a broad sense, and includes a shutter, a gate, and the like. Further, the non-control electric lock 15 is not limited to the door, and may be provided at another opening / closing portion such as a window. In addition, an uncontrolled electric lock 15 is provided at a plurality of open / close locations to prevent forgetting to lock.
If connected to 18, the non-control electric lock 15 can be easily added without increasing the number of door opening / closing confirmation sections 13c.

(B) The indicator 13-3 displays a message. Alternatively, a voice instruction may be issued.

(Effect of the Invention) As described above in detail, according to the present invention, the second and third opening / closing confirmation sections and the third locking / unlocking confirmation section are connected to the first opening / closing confirmation section in a loop. Since the first opening / closing confirmation section confirms whether or not the user has forgotten to lock the door, the door gate terminal device at the time of leaving the room can easily and accurately confirm that the user has forgotten to lock the uncontrolled electric lock. Thereby, security in crime prevention is surely improved. In addition, loop-like connection work and the installation of indicators are possible at low cost,
Moreover, since the locking and unlocking operation is as easy as in the prior art, no special labor is required for the person leaving the room. Further, without increasing the number of the first opening / closing confirmation sections, it is possible to easily add an uncontrolled electric lock only by a loop-like connection operation for the first opening / closing confirmation section.
