BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0015]
FIG. 1 is a schematic diagram of a monitoring target facility to which the security system of the present invention is applied.
[0016]
FIG. 1A is a schematic diagram of an N-floor floor of an office building. On the N-floor floor, individual management areas 1, 2, 3, and 4, in which tenants A to D live, are located. There is a machine room 5 for maintenance of the floor and a common part 100 which is an area for the entire tenant. Each of the individual management areas constitutes a security area provided with an independent security system, and the common unit 100 also has a common unit sensor 101, a common unit operation unit 102, and a common unit control device 103 for guarding the common unit. Security system consisting of: It should be noted that access to the floor 100 in this embodiment is performed using the elevator 6.
[0017]
FIG. 1B is a schematic configuration diagram of a security system of the tenant A. The security system includes a sensor 11, a security switch 12, a locking / unlocking recognition unit 13, and a control device 14. The sensor 11 is mounted in the area 1 of the tenant A and detects an intruder in the area 1. The security switch 12 is attached to the vicinity of the entrance door 15 outside the area 1, and performs a switching operation to set the security system to the security state or the security release state. The locking / unlocking recognizing means 13 recognizes a locked state or an unlocked state of a locking means (not shown) of the entrance / exit door 15, and includes, for example, a microswitch or the like for recognizing a state of a dead bolt of the door.
[0018]
As shown in the system configuration of FIG. 2, the control device 14 is connected to the sensor 11, the security switch 12, and the lock / unlock recognition unit 13, and when the management area 1 is set to the security state by operating the security switch 12. Outputs a security-on signal and a security-off signal when the security is released. When the sensor 11 detects a person, it outputs an intruder detection signal only when the management area 1 is in a guard state.
[0019]
Regarding tenants other than tenant A, even if a security system having the same intrusion detection sensor as that provided for tenant A is provided, or a security system is not provided, It is assumed that a lock recognizing means and a control device for outputting a recognition result of the lock / unlock recognizing means are provided.
[0020]
The common unit sensor 101 is installed in a common common unit 100 other than the tenants A to D, the machine room 5, and the elevator 6, and detects an intruder in the common unit 100.
[0021]
The common unit operating means 102 is installed in the common unit 100 and is operated for canceling a detection signal when the common unit sensor 101 detects a human body, and includes, for example, a card reader and a numeric keypad.
[0022]
The common unit control unit 103 is connected to the control device 14, the common unit sensor 101, and the common unit operation unit 102 of the individual management areas 1 to 4 of each tenant, and is also connected to the monitoring center 300 through a public line or a dedicated line. When receiving an intruder detection signal from each control device 14, the control unit 14 transmits an abnormal signal to the monitoring center 300. Further, when receiving either the security ON signal or the locking signal of the entrance door of the tenant having no security device from all the tenant control devices 14, the timing is started immediately or by the timer of its own to start the predetermined time. After a lapse of time, the common unit sensor 101 is enabled. Then, when the common unit sensor 101 detects an intruder in that state, an abnormal signal is transmitted to the monitoring center 300.
[0023]
(Example 1)
The operation of the first embodiment of the multi-area security system having the above configuration will be described with reference to the flowchart of FIG.
[0024]
In the floor of FIG. 1, when all tenants have exited, the final exit of each tenant locks the respective entrance door, and operates a security switch when a security device is provided. It turns on, leaves as a security state, and leaves the floor using the elevator 6. In the case of a tenant without a security device, the tenant locks the door and exits.
[0025]
Here, when all the tenants put the security system in the security state, or when the entrance door is in the locked state, the common unit control device 103 sets all the tenants in the security state or the locked state by a signal from the control device of each tenant. Is detected (S1). Then, the common unit control device 103 starts counting time using the timer (S2). After a lapse of a predetermined time, for example, three minutes, the common unit sensor is enabled, the security of the common unit is turned on, and the timer stops counting (S4). By doing so, for example, even if a certain tenant forgets to switch the security device to the security state at the time of the last exit, as long as it recognizes the locked / unlocked state of the entrance door, the common unit can be used. Even if all of the tenants have departed, the common unit does not remain in a security-free state, and it is possible to avoid leaving the common unit in a security-free state.
[0026]
The setting of the predetermined time is appropriately determined in consideration of the size of the facility to be monitored, but is slightly longer than the time required for a regular tenant user to leave the tenant after leaving the tenant. It should be set for a long time. By doing so, the abnormality signal is not output to the monitoring center when the common unit sensor 101 detects a legitimate user.
(Example 2)
Next, a description will be given of a second embodiment of the multiple area security device according to the present invention.
[0027]
Note that the present embodiment is characterized in that in the system configuration shown in FIG. 2, the processing is performed using the common unit operation means 102, and thus the processing performed by the common unit control device 103 is different from that of the above-described embodiment. I have.
[0028]
The common unit control unit 103 is connected to the control device 14, the common unit sensor 101, and the common unit operation unit 102 of the individual management areas 1 to 4 of each tenant, and is also connected to the monitoring center 300 through a public line or a dedicated line. When receiving an intruder detection signal from each control device 14, the control unit 14 transmits an abnormal signal to the monitoring center 300.
[0029]
In the present embodiment, when either the security ON signal or the locking signal of the entrance door of a tenant without a security device is received from all the tenant control devices 14, the common unit sensor is immediately enabled and the timer is activated. To start timing. Then, in this state, the common unit sensor 101 detects a human body. If a detection signal detected by the common unit sensor is valid after a lapse of a predetermined time, an abnormal signal is transmitted to the monitoring center 300.
[0030]
Next, the operation of the second embodiment of the multi-area security system of the present invention will be described with reference to the flowchart of FIG.
[0031]
First, when all the tenants put the security system in the security state or put it in the locked state, the common unit control device 103 sets all the tenants to the security state or the locked state by a signal from the control device of each tenant. Is detected (S10). Then, the common unit control device 102 activates the common unit sensor 101 to turn on the security of the common unit (S11), and at the same time, starts counting time with a timer (S12). When the common unit sensor 101 detects a human body in this state (S13), it is determined whether or not the clocking started in step 12 has passed a predetermined time (S14). If the predetermined time has elapsed, an abnormal signal is sent to the monitoring center (S16). The predetermined time is set in the same manner as in the first embodiment.
[0032]
The shared unit control device 103 determines whether the shared unit operating unit 102 has been operated before the predetermined time has elapsed (S15). If the shared unit operating unit 102 has been operated, the shared unit control unit 103 determines whether the shared unit operating unit 102 has been operated. The human body detection signal detected by the sensor 101 is canceled (S17). Therefore, when the common use section operating means 102 is operated within the above-mentioned predetermined time, the human body detection signal detected by the common use section sensor 101 is temporarily canceled, and the process ends.
[0033]
On the other hand, for example, when the last leaver does not operate the common use section operation means 102 and the above-described predetermined time has elapsed, the human body detection signal is held as it is, so that an abnormal signal is output in step 16 and It is transmitted to the monitoring center 300.
[0034]
In the present embodiment, for example, since the last tenant's leaver leaves within a predetermined time and there is an intruder in the meantime, even if he / she leaves, the intruder does not know the operation of the common section operating means 102. Is detected by the common unit sensor 101, and after a predetermined period of time, it is detected that an intrusion has occurred by sending an abnormal signal. In the case of the first embodiment shown in FIG. 3 described above, an abnormal signal is not transmitted when an intruder is within a predetermined time and the vehicle leaves, but in this embodiment, the abnormal signal is also generated in this case. It is sent out and the security effect can be further enhanced.
[0035]
Next, a third embodiment of the multiple area security device of the present invention will be described.
[0036]
As shown in FIG. 5, this embodiment is characterized in that the storage unit 400 is provided in the shared unit control device 103.
[0037]
In the above-described embodiment, when the individual management areas 1 to 4 are in a security state or a locked state, these individual management areas 1 to 4 are regarded as being in an unmanned state, and the shared unit control device 103 Based on the input of the security ON signal and the locking signal, it is determined that all the individual management areas 1 to 4 are in the security state or the locked state. The common unit control unit 103 enables the common unit sensor 101 to turn on the security of the common unit 100.
[0038]
However, depending on the tenant or the like, for example, in order to tighten the management, the entrance door is always unlocked in the individual management area where the entrance door is always locked, during the daytime, when many people enter and exit, at night, There is an individual management area (hereinafter, collectively referred to as a “specific individual management area”) in which the entrance door is always in a locked state during a time period during which the number of people has decreased. In such a specific individual management area, when entering or leaving the room, the eligibility of the person entering or leaving the room is judged by a collation device such as a card reader or numeric keypad installed near the entrance, and only when entry and exit is permitted, The entrance door of the specific individual management area is temporarily unlocked.
[0039]
Therefore, in a facility having such a specific individual management area, the fact that the entrance doors of all the other individual management areas including the specific individual management area are locked means that the facility has become unmanned. Absent.
[0040]
A specific description will be given with reference to the above embodiment and FIG. Here, tenant A is a specific individual management area, and tenants B, C, and D are other individual management areas that are not specific individual management areas.
[0041]
Since the entrance door 15 of tenant A, which is a specific individual management area, is always locked, tenant A is determined to be in a security state by shared unit control device 103 even though tenant A still has employees. . If the tenants B, C, and D enter the security state or the locked state in this state, the common unit control device 103 activates the common unit sensor 101 and turns on the security of the common unit 100. After that, when the employee of tenant A tries to leave the room, the security of the common unit 100 is already on, so the common unit sensor 101 works effectively to detect the employee of tenant A, and the common unit control device 103 The employee of A is determined to be an intruder, and an abnormal signal is sent to the monitoring center 300, and an unnecessary signal is sent to the monitoring center 300.
[0042]
In order to solve such a disadvantage, a third embodiment of the present invention will be specifically described.
[0043]
FIG. 5 is a diagram showing a part of an internal configuration diagram of the shared unit control device 103 shown in FIG. 1, and 400 in the figure indicates a storage unit.
[0044]
The storage unit 400 stores information for specifying a tenant or the like which is a specific individual management area. In this embodiment, the storage unit 400 stores the tenant information of the individual management area where the entrance door of the tenant or the like is always locked, and the information of the specific individual management area described above is stored in the storage unit 400. ing. Therefore, the common unit control unit 103 stores in advance an individual management area in which the entrance door is locked regardless of whether the individual management area is in the manned state or the unmanned state.
[0045]
At least the security switch 12 needs to be installed in this specific individual management area. This is for grasping the security state of the specific individual management area by the switching operation of the security switching device 12. The description of the parts already described is omitted.
[0046]
As in the above description, a case where only tenant A is the specific individual management area will be described with reference to FIG.
[0047]
In FIG. 1, when an employee of tenant A, which is a specific individual management area, leaves the company, this employee exits tenant A and performs a switching operation of security switch 12 to put the security system of own tenant A in a security state. Then, based on the input of the security ON signal and the locking signal from control device 14, shared unit control device 103 recognizes that tenant A has entered the security state. In this state, when the common unit control device 103 determines that the other individual management area other than the specific individual management area is in the security state or the locked state, the common unit sensor 101 is enabled and the security of the common unit 100 is enabled. Turn on.
[0048]
As a result, if the specific individual management area does not enter the security state, the common unit control device 103 can control the common unit 100 even if all the individual management areas other than the specific individual management area enter the security state or the locked state. Since the security is not turned on, it is possible to prevent a false report from being transmitted by a person who has left the specific individual management area.
[0049]
【The invention's effect】
As is apparent from the details described above, according to the multiple area security system of the first aspect of the present invention, even if one or more of the individual management areas in the monitored facility does not have the security system, If the entrance door of the management area is in the locked state, the common unit can be set in the security state, and it can be avoided that the common unit is left in the non-security state.
[0050]
Further, according to the multiple area security system of the second aspect of the present invention, the common unit is set to the security state after a predetermined time from the point in time when all the individual management areas are in the security state or the locked state, so that the common unit sensor can be used. By detecting a regular exit from the individual management area, it is possible to prevent an abnormal signal from being transmitted to the monitoring center.
Further, according to the multiple area security system of the invention described in claim 3, even when the security on operation by the security switch of the security system is forgotten in any one of the individual management areas, the entrance door of the individual management area is locked. If it is in the state, the common unit can be set in the security state, and it can be avoided that the common unit is left in the non-security state.
[0051]
Further, according to the multi-area security system of the invention described in claim 4 , the common unit sensor can be properly exited from the individual management area within a predetermined time from when all the individual management areas are in the security state or the locked state. When the exit unit operates the common unit operation unit within the predetermined time, it is possible to cancel the transmission of the abnormal signal to the monitoring center due to the detection of the exit unit by the common unit sensor. In addition, it is possible to prevent unnecessary abnormal signals from being transmitted.
[0052]
Further, according to the multiple area security system of the invention described in claim 5 , the common unit control device does not turn on the security of the common unit unless the specific individual management area is in the security state. It is possible to prevent a false report from being transmitted by a person who has left the room.
