DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an entrance / exit management device using an ID code,
The present invention relates to a room entrance / exit management device for grasping a room presence state by a predetermined operation of an ID code and a door.

(Prior Art) Conventionally, as a technology in such a field, for example, there is one shown below.

This type of device is intended for the purpose of restricting entry of persons other than the authorized person to a specific place, and as a basic configuration, a card reader, electric lock,
It consists of a controller. However, these days, "locking / unlocking" in each room requires functions such as lighting, cooling / heating control, crime prevention, and detailed response to disaster prevention.
It is becoming necessary to understand.

In order to deal with this, conventionally, as shown in FIG. 4, an unlock button 4 is provided in the room in addition to a card reader 1 outdoors, an electric lock 2 and a controller 3 indoors. In the case of locking and leaving the room, the unlock button 4 is pressed to determine "present" from the card operation to the pressing of the exit button 4.

Further, as shown in FIG. 5, a TV camera 5 and a heat ray sensor 6 are installed in the room to determine "presence or absence".

(Problems to be Solved by the Invention) However, in the device having the above-described configuration, there is a problem that cost is increased by adding a device such as an exit button, a TV camera, and a heat ray sensor, and the aesthetic appearance is deteriorated due to installation of the device.

In order to solve the above problems, the present invention does not require additional equipment such as a leaving button, a TV camera, a heat ray sensor and the like as in the conventional case. That is, it is an object of the present invention to provide an inexpensive entrance / exit management device that can judge "presence / absence" within a range of basic configurations of a card reader, an electric lock, and a controller, without impairing aesthetics.

(Means for Solving Problems) In order to solve the above problems, the present invention provides an electric lock that can be electrically locked / unlocked with an ID code reading unit and mechanically unlocked from a room, and an ID code. In a room entrance / exit management device that includes a storage device that stores an ID and a control unit that locks and unlocks the electric lock,
The code is read, the ID code is compared with the data in the storage device of the control means, and if they match, the electric lock is unlocked, and after unlocking, the door transits to a closed->open-> closed state,
After confirming that the door has been unlocked by means of locking and setting the occupancy status display and mechanical means such as thumb turn from inside the room, the door transits to the state of closing → opening → closing, ID within a certain time A code is read, the ID code is collated with the data in the storage device of the control means, and if they match, a means for locking the electric lock and resetting the occupancy status display is provided. .

(Operation) According to the present invention, as described above, with the basic configuration of the card reader, the electric lock, and the controller, it is determined that the card operation before the door is opened and closed is the card operation when entering the room,
Also, it is possible to grasp "presence / absence" by judging the card operation after the state transition of the door open → closed from the change of the unlocking of the electric lock by mechanically unlocking from the room as the card operation when leaving the room. With this configuration, it is possible to enhance the function with a simple structure and without impairing the aesthetic appearance.

(Example) Hereinafter, the Example of this invention is described in detail, referring drawings.

FIG. 1 is an overall configuration diagram of an entry / exit management apparatus showing an embodiment of the present invention, FIG. 2 is a time chart at the time of entry of the present invention, and FIG.
The figure is a time chart for leaving the room according to the present invention.

In these figures, 11 is an I in which an ID code is written.
D card, 12 is a card reader as an ID card terminal device, 13 is a controller, 14 is a memory, 15 is a central processing unit (CPU), 16, 17 and 20 are interfaces, 18 is a timer, and 19 is an in-room status display. The device 21 is an electric lock, which is not shown, but this electric lock has a built-in switch for confirming locking / unlocking and a switch for confirming opening / closing of the door.

First, the operation when entering the room will be described with reference to the time chart of FIG.

When entering the room, the ID card 11 is inserted into the card reader 12 from the outside and the ID code is read by the controller 13 through the interface 16. Then, the ID code stored in the memory 14 built in the controller 13 and the read ID code are collated by the central processing unit 15,
As a result, if the ID code is a previously stored entry permission ID, the controller 13 outputs an unlocking control signal S ₁ via the interface 17 and sends it to the electric lock 21 to unlock it.
Then, the unlocking state signal S ₂ is sent from the electric lock 21 to the controller.
Sent to 13. Then open the door. Then, the door changes from the closed state to the open state, and the open state signal of the door
S ₃ is sent to the controller 13, read and stored. So I enter the room and close the door. Then, the door transits from the open state to the closed state again, and the door closed state signal S ₄
Is sent to the controller 13 and read. In this way, when the door makes the transition from closed to open to closed, the lock control signal S ₅
Is sent from the controller 13 to the electric lock 21, and the electric lock 21 sends a lock state signal S ₆ to the controller 13, whereby the central processing unit 15 causes the occupancy state display device 19 to operate.
A signal is sent to and the occupancy status display is set. In addition,
This occupancy status display signal is sent to a device relating to lighting, cooling / heating control, crime prevention, and disaster prevention via the interface 20.

Next, the operation when leaving the room will be described with reference to the time chart of FIG.

Unlock from the room by mechanical means such as thumb turn. That is, the locked / unlocked state is changed from “locked” to “unlocked”, and the electric lock 21 has the unlocked state signal S ₂ read by the controller 13 via the interface 17. When the door is opened, the door open state signal S ₃ is sent to the controller 13 and read. Then, open the door, leave the room, and close the door. Then, the door closed state signal S ₄ is read by the controller 13. Therefore, the ID card 11 is read from outside the room. Then,
If the ID card is a previously stored entry permission ID card, the controller 13 outputs the lock control signal S ₅ to the electric lock 21 via the interface 17 to lock the electric lock 21, and the electric lock 21 outputs the lock state signal S ₆ to the electric lock 21. To the controller 13,
As a result, the central processing unit 15 sends a signal to the occupancy status display device 19 to reset the occupancy status display. That is,
In this state, the absence is displayed, and this absence display signal is sent to the devices related to lighting, cooling / heating, crime prevention, and disaster prevention via the interface 20 to control various devices.

In the above, the door is opened, the room is exited, and the door is closed. Then, the door closed state signal S ₄ is read by the controller 13. When the door closed state signal S ₄ is read by the controller 13, the timer 18 starts and clocks, and the in-room state display is not reset unless the ID card 11 is read by the card reader 12 within a fixed time.

The present invention is not limited to the above embodiment,
Various modifications are possible based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

(Effects of the Invention) As described above in detail, according to the present invention, despite the basic configuration of the card reader, the electric lock, and the controller, the card operation before the open-closed state of the door is performed when entering the room. It is judged that it is a card operation of, and the electric lock is applied by mechanical unlocking from the room → The change of the solution is detected, and the card operation after the door open → closed state transition is regarded as the card operation when leaving the room. Since the judgment is made so that the “presence or absence” can be grasped, it is possible to enhance the function with a simple configuration and without impairing the aesthetics.

Therefore, it is possible to improve the functions such as energy-saving measures such as turning off the lighting and cooling / heating in the absence, and crime prevention measures such that the door opening in the absence is judged as the door intrusion and an alarm is generated.

As described above, while the function can be improved, the cost increase can be suppressed and the cost effectiveness is great.
