Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a management system interlocking type key storage device used in a building that requires different management systems for a plurality of users such as a tenant building.

[0002]

2. Description of the Related Art Conventionally, security for buildings and security for fire prevention have all been performed manually. In addition, it was necessary to check the locks on windows, etc. one by one and then exit. However, in recent years, it has become possible to let the building management system do all of the above work.

The building management system will be described.
FIG. 9 is a schematic diagram of the system. There are users (tenants) on each floor and each room of the tenant building 1. The time of use differs depending on each tenant, and the security content differs for each tenant. Therefore, each tenant (1a, 1b in the figure) is provided with a management device S such as a crime prevention / fire protection detector 2, a lock confirmation sensor 3, and an electric equipment power switch 4. Where 1c
Will be the common area of the building such as the lobby, hot water supply room and elevator.

The management device S is connected to a centralized monitoring board 5a in a monitoring room 5 installed in the building 1. At the entrance 6 of the building, a key box 7 having a plurality of key storages 7a, 7b ... Is installed and connected to a central monitoring board 5a of a monitoring room 5 in the building. The centralized monitoring board 5a is connected via a transmission line 8 to a monitoring center 9 of a security company, which is located at a remote place. In many cases, the monitoring room 5 is not provided in the building, only the centralized monitoring board 5a is installed, and the monitoring staff is not permanently stationed in the building. When an emergency occurs in each tenant, the centralized monitoring board 5a and the monitoring center 9 are immediately notified.

A tenant of a building having such a building management system is rented with a key for each room or floor and an identification card. Here, the operation procedure of the system will be described. For example, if the last person leaving the tenant 1a returns the key to the key box 7 when approaching the door after locking
The tenant 1a enters the security system, and the electric equipment power switch 4 turns off the power of the lighting and air conditioning equipment. The security status is sequentially reported to the monitoring room 5 and the monitoring center 9. When all the tenants in the building have returned the key to the key box 7, the common use part 1c of the building is automatically put in the security posture, and the lighting and electric devices are turned off.

10 and 11 are schematic views of the key box. FIG. 11 is an enlarged view of the card reader 10 and the ten-key pad 11 of the key box. When the tenant 1a returns the key to the key box 7, the identification card is inserted into the card reader 10 provided in the key box 7. Then, by inputting the personal identification number with the ten keys 11, the door of the key storage 7a assigned to the tenant 1a is opened. Inside the key storage 7a, a cylinder lock that engages with the key lent to the tenant 1a is installed, and by inserting the key into the cylinder lock and rotating it, the tenant 1a enters the security state as described above. . Further, in this state, the key cannot be removed from the cylinder lock, and the key is put in the storage state by closing the door of the key storage.

When the key is taken out of the key box 7, the identification card is inserted into the card reader 10 and the personal identification number is inputted by the ten-key pad 11 to open the door of the key storage 7a. By rotating the inserted key in the opposite direction to the previous one, the security posture of the tenant 7a is released, and the key can be pulled out from the cylinder lock. It is possible to record all the delivery of the above keys in a printer or the like (not shown).

[0008] Such a building management system has been put to practical use and unmanned operation has been promoted, and each tenant can carry around the identification card so that there is no need to make a duplicate key and a more reliable security system can be provided. It has become possible. As a conventional example of the building management system, Japanese Patent Laid-Open No. 59-59
-41099 and Japanese Patent Laid-Open No. 59-231698, etc. A key management system applied to the building management system is disclosed in JP-A-59-122676.

[0009]

However, the above-mentioned conventional method has the following problems. A key storage at a predetermined position is assigned to each tenant.
That is, the storage location of the key is clear for each tenant,
There is a possibility that a third party can know. In that case, if the door of the key storage can be broken, it will be easy to take out the key. Of course, if you do something that breaks the door, the situation will be reported, but between the reception of the security guard and the arrival at the scene, the guards are pushed into the tenant and important items are stolen. There is a possibility. Also, put the key in the key box 7
If the assigned key storage was damaged when returning it to, the maintenance staff had to be called in for repair, which was very troublesome.

The present invention has been made in view of the above problems, and an object of the present invention is to allocate a specific key storage to each tenant and to release an arbitrary storage every time it is used. It is to make the storage location of the key unclear and make it difficult to rob the key. Further, it is possible to install more storages than the maximum number of tenants and to always prepare a spare storage together with the arbitrary selection function of the storages.

[0011]

Means for Solving the Problems According to the present invention for solving the above problems, there is provided a key box which can be interlocked with a crime prevention, fire prevention device, a power supply device, etc. provided in each room or floor of a building, In a building management system interlocking key storage device capable of remotely controlling the operation of the crime prevention, fire prevention device, and power supply device in a specific room or floor in response to a signal from the detection device provided in the key box A key storage is provided, and a selection means for opening an arbitrary door among the plurality of key storages is provided, an identification means is attached to the key of each room, and a detection device for the identification means of the key is provided. It is characterized by being provided in the key box.

In the present invention, it is preferable that the key identifying means is a key holder that is rotatably fixed to the key and is capable of individual identification. In addition, it is desirable that the key storage of the key box is arranged more than the maximum number of users of the building.

[0013]

In order to use the present invention, the final exit of each tenant locks the final exit of each tenant with a key. When the identification card is inserted into the card reader of the key box and the personal identification number is input, an arbitrary key storage is selected by the CPU and the door is opened. Insert the key into the internal structure of the key storage,
When the storage is closed, the CPU recognizes that the key has been returned by the detection device, and the corresponding portion of the display unit lights up. Then, only the room where the key was returned will automatically enter the security system.

The key is taken out by inserting the identification card into the card reader and inputting the personal identification number, the door of the key storage of the tenant is opened, and when the key is taken out from the internal structure of the key storage, the CPU reads it.

When the door 12 is released, the internal structure 16 sticks out to the front and can be removed. The operation of the internal structure 16 is performed by using a driving device such as a motor or by combining an elastic body such as a spring with a link structure. When returning the key 15 to the key storage, the key holder 14 is inserted into the internal structure 16 of the key storage while maintaining the directional relationship shown in FIG. At this time, the internal structure 1
A plurality of pressing detection switches are arranged on the surface 16a facing the one surface 14a on which the concave and convex portions of the key holder 14 of No. 6 are arranged. This pressure detection switch detects the unevenness that is the identification means and determines which key holder is returned to which key holder.
It can be managed by a CPU (not shown) provided in the key box.

Next, a schematic diagram of the system of the key storage device according to the present invention will be described with reference to FIG. The input unit 18 indicates the crime prevention / fire prevention detector 2, the lock confirmation sensor 3 and the like in FIG. 9, and transmits the security state to the CPU 22. The output unit 19 operates the building management system in synchronism with the removal of keys, and specifically operates the electric equipment power switch 4 such as lighting, air conditioning, and elevator, and is controlled by the CPU 22. . Storage section 2
Reference numeral 0 corresponds to the identification means and knowledge device of the key storage 7N and the key ring 14. The display unit 13 is attached to the main body panel of the key holder 14 as shown in FIG. 2, and displays the storage status of keys for each tenant and whether or not they are in a security posture. In addition, the operation unit 21 is the ten-key
It is also composed of a display means such as an LCD and is used for inputting ciphers and maintenance management of system data. Card reader 10
Is installed on the main body panel of the key chain 14 and reads the recorded contents of the identification card to release the system to the user. The interface unit 23 communicates with the outside, and specifically corresponds to a signal transmitting unit for the transmission line 8 in FIG.

Now, of the operation procedure of the key storage device according to the present invention, a flow chart for returning the key will be described with reference to FIG. First, the final exit of each tenant locks the windows and the like, and locks the final exit of each tenant with the key 15 (a). Then, the identification card lent to each tenant is inserted into the card reader 10 of the key box 7 provided in the vicinity of the entrance 6 (a). The building management system is released to this tenant employee (c). Here, the personal identification number set for each tenant is input with the ten keys 11 (d).

At this point, the CPU 22 selects any key storage (e) except the key storage in use and the storage which is judged to be defective due to some trouble, and the selected key storage is selected. Instruct to open the door 12 of (F). The key chain 14 is fitted into the internal structure 16 of the storage (g). The unevenness is identified by the press detection switch provided on the surface 16a facing the unevenness provided on the one surface 14a of the key holder 14 (h). The CPU 22 recognizes in which storage box the key of the tenant has been returned, and displays 13 on the display unit.
Indicates that the tenant key is in the storage state (K).

Here, when a tenant returns the key and other tenants still remain in the building, only the room or floor used by the tenant returning the key is put in a security system. Yes (ko). If the tenant employee who returned the key is the last person to leave the building, the entire building, including the building common area, will have a security system.

Next, of the operation procedure of the key storage device according to the present invention, a flowchart for taking out a key will be described with reference to FIG. Tenant employee enters and key box 7
The identification card is inserted into the card reader 10 of (S). The building management system is open to this tenant employee. Here, the personal identification number set for each tenant is input using the ten keys 11 (step S). CPU
Since 22 recognizes in which key vault the key ring of this tenant is stored, the key vault storing the key of this tenant is selected (SO), and its door 1
Instruct to open 2 (T). The tenant employee takes out the key ring 14 (h). On the display unit, this tenant displays that the key has been taken out and that the security system of the tenant has been released (Tsu).

At this time, if this tenant is the first visitor in the entire building, the security system for the building common area and the room or floor used by the tenant is released (T). Further, when another tenant is in the building, the security system of the room or floor used by the tenant who has taken out the key ring 14 is released (g).

Various combinations are conceivable for the above-mentioned operation procedure, and for example, input of a personal identification number (10
It is also possible to omit (S) and select the key storage to be released (O, S) after inserting the identification card (A, S).

With the above configuration, each time the tenant returns the key to the key box, the position of the key storage is assigned.
I don't know where the key is. Therefore, it is difficult to specify the position of the key storage in order to enter the specific tenant, and the damage caused by the theft due to the destruction of the key box is prevented. Also, since there are more key storages than the maximum number of tenants in the building, even if one or several key storages are out of order, select the return location from the normal key storages. As a result, the key storage is always assigned to the tenant, so there is no need to wait for the arrival of maintenance personnel for repairs. Further, since the key identifying means is provided in the key ring, it is possible to reliably deliver the key without making a mistake, and there is no restriction on the manufacturer and shape of the key.

Next, a second embodiment will be described with reference to FIG. The difference of the second embodiment from the first embodiment is that in the second embodiment, a bar code is arranged on one surface 14a of the key holder 14 to serve as an identification means. Therefore,
A bar code reader is arranged on the surface 16a of the internal structure 16 of the key storage. The second embodiment configured in this way can also obtain the same operational effects as the first embodiment.

Next, the third embodiment will be described with reference to FIGS.
I will explain based on. The third embodiment differs from the first embodiment in that a magnetic material is arranged on one surface 14a of the key holder 14 to serve as an identification means. Therefore, a magnetic reader is arranged on the surface 16a of the internal structure 16 of the key storage. In addition, as shown in FIG. 6, the key chain 1
It is also possible to identify 4'by making it into a general shape, arranging a magnetic substance on this, and providing a magnetic substance reading device in the internal structure of the key storage. The third embodiment configured in this way can also obtain the same effects as the first embodiment, and by using the key chain 14 ', the degree of freedom in setting the shape of the key chain and the key storage. Will increase.

Next, a fourth embodiment will be described with reference to FIGS. 1, 6 and 7. The fourth embodiment is different from the first embodiment in that a radio wave transmitter is arranged inside the key holder 14 to serve as an identification means. As shown in FIG.
An antenna 27 installed inside the key box 7 receives a radio wave from a transmitter 28 embedded in each key holder, and sends data to the CPU 22 via a controller 29. The CPU 22 identifies the storage position from the received data. In addition, as shown in FIG. 6, the key chain 1
It is also possible to make 4'general shape and to provide a transmitter inside. The fourth embodiment configured in this way also
The same effect as that of the third embodiment can be obtained.

Next, a fifth embodiment will be described with reference to FIG. The feature of the fifth embodiment is that the key box 7 is provided with a key ring entrance / exit 24, a multi-stage key storage box 25 is provided therein, and a key chain transfer means 26 is provided to open / close each key storage box and the key ring entrance / exit. Is what connects them. Inside the key box 7, a rotor section 25a is provided as a multistage key storage. The rotor part 25a is provided by arranging four key storages 25b arranged in a row in a circumferential shape and stacking them in a multi-step manner. Further, it has a drive means for rotating the shaft 25c as a center and moving it up and down with the shaft 25c as a guide. The key chain 14 is a key storage 25
It has a shape that can be inserted into b and has an identification means.
The identification means and the detection method are the same as those described in the first to fourth aspects.
This is as described in the examples. Further, similarly to the coin box 7 described in the first embodiment, it has a card reader 10, a ten-key pad 11 and a display unit 13.

In this embodiment, when the storage position of the key holder 14 is determined, the key storage box 25b of the storage destination is aligned with the position of the key holder transfer means 26 while vertically moving and rotating the rotor portion 25a. Therefore, by inserting the key ring 14 into the doorway 24, the key storage 2
Stored in 5b. Further, when the key 15 is taken out, the rotor portion 25a is operated, the key storage 25b storing the necessary key holder 14 is aligned with the position of the key holder transfer means 26, and the key holder entrance 24 is pushed out. With the above configuration, the storage location of the key of each tenant cannot be known from the outside, and the same operational effect as in the first embodiment can be obtained.

[0032]

As described above, the present invention has the following effects. Since the key box is provided with a plurality of key storages and has a selection means for opening any door of the plurality of key storages, if the selection means is used to sequentially open the doors of any key storage. , The storage location of each user's key is not fixed. Therefore, it is impossible for anyone other than the person who was there to store the key in the key box to identify the key storage location, and the possibility that the key of a specific tenant could be stolen from the key box is reduced. .

Further, when the storage device is made to recognize the identification means of the key holder attached to each key and is taken out again,
Since the door of the key vault with the required key will definitely be opened, the key can be delivered without fail even if the key storage location is not fixed for each tenant.

In the present invention, since the key chain is rotatably fixed to the key and used as the key identifying means,
It is possible to identify regardless of the manufacturer and shape of the key body. Also, it is easy to mount and carry, and it does not affect the usability of the key body. Since the key chain itself uses a material that can be easily molded, it has good productivity. The key holder has a plate-like shape, and one surface of the key holder is provided with unique irregularities, and the key storage has a structure in which the key holder is inserted, and the key holder has a concavo-convex surface. Since the press detection switch is arranged at the position to detect the unevenness which is the identification means, it is possible to reliably identify each key holder.

Further, it is possible to identify each key chain by providing a unique bar code for each key chain on one surface of the key chain and providing a detection device for reading the bar code in the key storage. .

When each of the key chains has a magnetic material that is uniquely magnetized, each key chain can be identified by the magnetic detection device provided in the key storage. Further, when each key ring has a transmitter that emits a radio wave of a unique frequency, the radio wave detection device provided in the key storage can identify the radio wave transmitted from each key ring. In this case, by installing only one antenna in the key box, it is possible to receive the radio waves of all key chains, and the structure is simple. In addition, since the shape of the key chain itself is not restricted, the degree of freedom in design is increased.

Further, since the key storage of the key box is arranged more than the maximum number of users of the building, and the storage position of the key of each tenant is sequentially selected arbitrarily,
Even if the key storage means fails in one or several places, it is possible to store the keys of all tenants. Therefore, it is not necessary to call maintenance personnel immediately in case of a failure, which improves usability.
