Description

Description: TECHNICAL FIELD The present invention relates to a mechanical security system that locks and unlocks a plurality of tenants by an ID discrimination device and monitors intrusion during locking.

[Conventional technology]

Generally, in a machine security system that guards a plurality of tenants by using an ID discrimination device, an information reading device such as a card reader is provided for each tenant, and an ID card or the like in which unique information unique to the user is stored. Each of the information reading devices reads the unique information from the storage medium to determine whether or not the user is authentic.

By the way, if the information readers cannot be installed for each tenant because the walls of each tenant are made of glass, etc., the information readers for each tenant must be installed together in a place where they can be installed together. .

However, in this case, a large installation space is required and an information reading device is required for each tenant, which is expensive, and the user is confused about which information reading device is the target device of the user, and operation is difficult. There are problems such as inconvenience.

Therefore, in some cases, as disclosed in, for example, JP-A-57-20567 or 59-91278,
A card lock control device has been proposed in which information can be read from a plurality of cards by a single card reader.

[Problems to be Solved by the Invention]

However, since the above-mentioned conventional card lock control device is intended only for lock control, it displays whether there is no display device or, even if there is a display device, which door the cardholder should enter. However, there was a problem that it was not possible to clearly know the status of the tenant.

The present invention has been made to solve such a problem, and a user can easily and surely know the status of his / her own tenant, and a person who comes later can also know the status of his / her own tenant. An object of the present invention is to obtain a mechanical security system that can be performed and has a simple device configuration and is inexpensive.

[Means for solving the problem]

A machine security system according to the present invention reads a storage medium for storing unique information, reads the unique information from the storage medium, determines whether a tenant corresponding to the unique information is monitored for intrusion, and monitors the intrusion. If the information is read, the unlocking and intrusion monitoring will be stopped if it is performed, and the locking and intrusion monitoring will be started if the intrusion monitoring is not performed. A common display device that is commonly provided for a plurality of tenants that displays whether or not the tenant is being displayed, and a plurality of tenants that are displayed for each of the tenants that re-displays whether or not the intrusion monitoring of the tenant is being performed after the determination is made. An individual display device is provided.

[Action]

In the present invention, the unique information of the storage medium corresponding to each of the plurality of tenants is read by a single information reading device, and locking / unlocking of each tenant and intrusion monitoring are performed.
At this time, the status of the tenant corresponding to the storage medium from which the unique information has been read is temporarily displayed on the common display device, and the user does not have to look for his or her own tenant's display among a plurality of individual displays. The state of the tenant of the self can be easily and accurately known only by the display contents of the common display device. On the other hand, since the status of each tenant is displayed for each tenant on the individual display device, a person who comes later can know the status of his / her tenant without using a storage medium from the displayed contents.

〔Example〕

FIG. 1 shows a collective card reader used in the mechanical security system of the present invention, and FIG. 2 shows a tenant in which this collective card reader is installed. In FIG. Shaped card reader, (2a), (2b),
(2c) and (2d) are four tenants 1 to 4 guarded by the collective card reader (1), (3a), (3b),
(3c) and (3d) are doors of the above-mentioned tenants (2a) to (2d) that are locked and unlocked by electric locks, (4a), (4b), (4c), (4).

OM, (17) is RAM, (18) is a clock, (19) is an interface, and the electric locks (20a), () of the intrusion sensors (4a) to (4d) and the tenants (2a) to (2d). 20b), (20
The c) and (20d) are connected to the collective card reader (1) through the interface (19).

Next, the operation of the above embodiment will be described with reference to the flowchart shown in FIG.

First, in step (31), it is determined whether or not the card is read. If the card is read, it is determined in step (32) whether or not it is the ID number of tenant N (N = 1 to 4). If the numbers are incorrect, step (33)
OK, NG light (8) NG light is turned on temporarily, and if the ID number is correct, in step (34), OK, NG light (8) OK light is turned on temporarily. In step (35), it is determined whether the electric lock of the tenant N is locked.

When the electric lock of the tenant N is locked, the electric lock of the tenant N is unlocked in step (36), and if the doors (3a) to (3d) are closed until now, the doors are opened. After that, in step (37), the indicator lamp (9) of the common display device (7) remains off, and in step (38), the indicator lamp (12) indicating that the tenant N is in the alarm state is turned off. In (39), the intrusion monitoring of the tenant N is stopped and the process returns to step (31).

On the other hand, if it is determined in step (35) that the electric lock is being unlocked, the doors (3a) to (3d) are closed if they are open, and then in step (40), the intrusion sensor of the tenant N is detected. It is determined whether (4a) to (4d) are in operation. If not in operation, lock the electric lock in step (40),
If the sensor display lamp (10) of the common display device (7) is turned on in step (42) while operating,
In step (43), the display lamp (13) for displaying the sensor of the tenant N is left on. Then, in step (44), if the person who has read the card returns by closing windows etc. so that the intrusion sensors (4a) to (4d) do not operate, then in step (45), the sensor indicator ( 10) is turned off, the display lamp (13) of the tenant N is turned off in step (46), and step (41) is executed. That is, the electric lock is locked.

Next, in step (47), after temporarily turning on the indicator light (9) for displaying the security of the common display device (7), the person who has read the card (user) is informed that the security state is set. In step (48), the display lamp (12) for displaying the security of the tenant N is turned on to start the intrusion monitoring.

After that, in step (49), it is checked whether or not the intrusion sensors (4a) to (4d) of the tenant N have operated, that is, whether or not there is an intruder.
In step (50), the display lamp (14) for displaying the intrusion of the tenant N is turned on, and in step (51), an alarm output is issued. As a result, the security company is automatically notified, and the guardman is urgently dispatched to take measures or the alarm is displayed in the manager's room and the manager takes measures.

Then, the user who has read the card can easily know the status of his / her tenant by the display contents of the common display device (7), and the person who came later can read the individual card without reading it. From the display content of the display device (11), it is possible to know the status of its own tenant.

In addition, in the said Example, the case where the number of tenants was 4 was shown, but 3 or less or 5 or more may be sufficient. Further, in the above embodiment, the card reader is used as the means for reading the unique information unique to the user, but another 1D identification device may be used, or a plurality of different types of ID identification devices may be used. You may

Further, in the above-described embodiment, the respective display lamps (8), (9), (10) of the common display device (7) are also the respective display lamps (12), (13), (14) of the individual display device (11). ) Also shows the case where each is provided separately, but all of them are put together in 1 such as CRT.
You may make it display on one display surface. Also, the individual display device (11) is not provided in the collective card reader (1),
It may be provided in a building entrance, a passageway for people leaving or leaving the office, and the display of the individual display device (11) is lit after the display of the common display device (7) is finished. You may do it. Further, the common display device (7) is provided with only the OK and NG lights (8) separately, and the other display lights (9) and (10).
The display unit (11b) of the corresponding tenant of the individual display device (11) may be flicker-displayed.

Further, in the above-mentioned embodiment, the case where the intrusion sensors (4a) to (4d) detect opening of the window is shown, but the door (3a)
A sensor that detects the opening of (3d) or the movement of a person may be used, or a combination of these may be used. Further, the doors (3a) to (3d) are not limited to the opening and closing type, but can be applied to other structural doors such as automatic doors and revolving doors.

〔The invention's effect〕

As described above, according to the present invention, even if there are a plurality of tenants, one information reading device can be provided, and the structure can be simplified and a small and inexpensive device can be obtained. At the same time as the unique information determination operation before locking, the lock status of the room is displayed from the intrusion detection result that is temporarily displayed on the common display, and at the same time when the intrusion monitoring that is temporarily displayed on the common display is performed at the same time as the unique information determination operation after locking. The security effect is improved because the completion status of the intrusion monitoring inside can be confirmed only in one's room without being mistaken for the intrusion monitoring status in other rooms. Also, for those who came later, depending on the display content of the individual display device,
There is an effect that it is possible to know the state of one's own tenant without using an information reading device.
