DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security device for monitoring office buildings, condominiums, detached houses and the like, and more particularly to a security device having a function of automatically setting a security area to a security state according to a schedule. Further, the present invention relates to a security system constructed with such a security device and a central monitoring device in a monitoring center.

[0002]

2. Description of the Related Art Conventionally, a monitoring center such as an office building, a condominium, a detached house or the like is connected to a monitoring center via a communication line such as a telephone line using various sensors such as an intrusion sensor and a fire sensor. There is known a security device which monitors and detects an abnormality by a sensor and sends an abnormality signal to a monitoring center through a communication line.

[0003] In these security devices, a security set that releases the intrusion sensor when there is a person inside the building during the daytime or the like and activates the intrusion sensor when the inside of the building becomes unmanned at night or on holidays or the like. Set to. For this setting, it is common practice that a security device is operated by a security device when a final exit person leaves the monitoring building. At this time, there is a problem that if the last retired person forgets to operate the security set, the guarded building is not guarded even though the monitored building is unmanned. Further, in order to solve this problem, there has been proposed a device in which a security set is automatically set at a preset time (for example, Japanese Patent Application Laid-Open No. HEI 9-134572).
4-324597).

[0004]

However, in these conventional security devices, the monitoring building is automatically brought into a security state at a preset security set scheduled time.
If there is a remaining person in the monitored building, there is a possibility that the security state is automatically set. In such a case, the sensor detects the remaining person as an intruder and reports an abnormality to the monitoring center. Then, in the monitoring center, the emergency responder rushes to the monitored building as an intrusion abnormality.

As described above, even if a residual person who is not a trespasser is detected, it is necessary to go to the countermeasure, and a useless countermeasure occurs. To prevent this,
In some cases, a message prompting the user to leave is issued by voice or display to provide a security set, thereby urging the user to leave. Even in this case, the message is not visible,
Alternatively, a useless notification may be made by detecting a residual person who is not a trespasser for reasons such as inaudibility.

[0006] Further, when the security set operation cannot be performed for some reason, such as being threatened by a malicious person,
It was difficult for the monitoring center to grasp the situation.

[0007] In addition, the scheduled security set time of each monitored building is stored in the central monitoring device, and if there is a monitored building to which no security set signal is sent by that time, the monitored building is left unguarded. As a matter of course, a security guard goes to the monitored building, checks the situation, and performs a set operation.

When it is desired to change the scheduled security set time in each monitored building, the monitoring center is contacted by telephone or the like to change the scheduled security set time stored in the central monitoring device at the monitored center. ing.

[0009] However, when the number of buildings monitored by the monitoring center is large, there has been a problem that telephone communication at the monitoring center and operations for changing them are very complicated.

In view of this situation, an object of the present invention is to prevent the security set operation from being performed even when the security set scheduled time has come, and to reduce the situation of the security area even when the security set operation is not performed. An object of the present invention is to provide a security device that improves security by enabling confirmation and setting of a security set. It is a further object of the present invention to provide a security system including such a security device.

Next, a security set processing procedure of the security device of the present invention will be described with reference to the flowcharts of FIGS.

First, it is assumed that the monitored building is in a security released state. The signal processing unit 1 includes a current time from the clock unit 5 and a security set time preset in the storage unit 4 (specifically, includes a time at which security is to be set, for example, 17:50 to 18:10). A predetermined time period (“security set time period”) is also compared (step 1).
02) If they match, a message indicating that the security set time has come is displayed, and a message prompting a security set operation or a security set time change operation is displayed on the display unit 3 (step 104). The display unit 3 may be any device, such as a liquid crystal display or a speaker, that can notify the user of the security set time or the time just before the extended security set time, irrespective of sight or hearing. If the security set time does not match, the comparison operation is continued until a preset security set time or a security set time extended by a change operation is reached.

Thereafter, when the user looks at the message on the display unit 3 and performs a security setting operation from the operation unit 2 (YES in the determination in step 106), the signal is input to the signal processing unit 1 and the security setting is performed. (Step 130), the security set signal is reported from the signal processing unit 1 to the central monitoring device 20 via the communication control unit 6 and the communication line 7 (step 132). By receiving the set signal, the monitoring center can confirm that the monitored building has been alerted.

On the other hand, if the security setting operation is not performed (NO in step 106), the process proceeds to step 108 in which it is determined whether the security setting time extension operation has been performed. In step 108, the signal processing unit 1 determines whether or not an extension operation for extending the security set scheduled time has been performed from the operation unit 2, and if there is an extension operation, the signal processing unit 1
The extended security set time is stored in the storage unit 4 (step 110), and thereafter, the determination operation of step 102 is repeated until the time comes.

Note that the security setting operation and the extension operation are performed according to I
It may be valid only when the operator can be confirmed by a D card or the like.

On the other hand, when there is no extension operation (step 1
No in step 08), the communication control unit 6 notifies the central monitoring device 20 via the communication line 7 of an unset signal indicating that the security has not been set to the monitoring center at the predetermined time. (Step 112).

The central monitoring device 20 installed at the monitoring center receives the unset signal from the security device via the communication line 7. Signal processing unit 15 of central monitoring device 20
Retrieves, from the storage unit 13, information on the monitored building in which the security device that has issued the unset signal is installed, for example, the monitored building name, and displays it on the display unit 12. The controller at the monitoring center can confirm that the guarded building that should be security-guarded is not guarded by looking at this display.

The controller inquires of the surveillance building on which such display is made, for example, by telephone, that the security start time has come, and determines the presence or absence of an appropriate user, the status of the surveillance building, and the like. To explore.

Here, if the presence of a proper user can be confirmed, the user is requested to extend the security set scheduled time or to perform the security set operation. Also, when recognizing the existence of an improper person such as a burglary, a security guard is dealt with.

Thus, even if the user cannot perform the security set operation or the security set scheduled time change operation such as the user forgetting the security set or being attacked by a robber, the monitoring center can grasp the state of the monitored building. It is possible to take appropriate measures.

On the other hand, if the controller judges that there is no person in the monitored building, it is highly possible that the user has left the set operation and left the facility. Therefore, the security surface is neglected. Therefore, the operation unit 11 is operated to send an automatic setting permission signal from the communication control unit 16 to the security device via the communication line 7.

In this embodiment, when the security device reaches the scheduled security set time, the security device is not set, and if there is no operation to extend the security set scheduled time, the security device sends an unset signal to the monitoring center. Is sent to the central monitoring device 2
At 0, the security set scheduled time of each security device is stored. If the set signal or the extension signal of the security set scheduled time is not received from the corresponding security device at the corresponding time, the unset signal is received. The display may be automatically displayed on the display unit 12 even without the display.

Thus, the signal processing unit 1 in the security device
Receives an unset signal from the central monitoring device 20 via the communication line 7 and the communication control unit 6 and receives an automatic set permission signal from the central monitoring device 20 (YES in the determination at step 114) to check the status of the monitored building. It is checked whether the sensor 9 is in a normal state (step 116). If all the sensors 9 are normal, that is, if no abnormality is detected, the process proceeds to step 120.

On the other hand, if the set permission signal is not transmitted from the monitoring center even though the communication line is normally connected, for example, if the user has the permission of the monitoring center (determination in step 114) NO), the security release state is maintained, and the process shifts to an appropriate process according to the instruction from the monitoring center.

As a result of the state check of the sensor 9 in step 116, if there is no problem, all sensors arranged in the monitored building are set to the tentatively set state to be monitored (step 120). However, if there is a problem such as the window being opened and the sensor being in the sensing state, the state N
The G signal is reported from the communication control unit 6 to the monitoring center via the communication line 7 (step 118), and thereafter, the processing shifts to an abnormality process according to an instruction from the monitoring center. When this state NG signal is received by the central monitoring apparatus 20, the monitoring center can recognize that it is the scheduled security set time, that the state is unmanned, and that the doors are not locked, and that any abnormal situation occurs. It is possible to take measures such as giving an instruction to emergency response personnel in the monitored building because of the possibility of occurrence of the situation.

When the monitored building enters the temporary set state, that is, the temporary security state, the timer unit 10 starts (step 12).
2). The time-up time of the timer unit 10 is set to a predetermined time, for example, 10 minutes, at which it is possible to determine whether or not a person remains in the monitored building, or whether or not the user is out of the monitored building for a short time. It is set in advance.

If the presence of a person cannot be confirmed while the timer section 10 is operating, that is, if the sensor 9 for detecting a occupant does not detect a person (N in the determination of step 124)
O) When the timer section 10 times out (YES in step 128), the security unit is shifted to the security state as a security set (step 130), and a security set signal notifying the fact is sent to the monitoring center (step 130). Step 132). By receiving the set signal, the monitoring center recognizes that the monitored building is in security.

On the other hand, if the sensor 9 detects a person during the activation of the timer section 10 (YE in the judgment of step 124).
S), a set NG signal is sent to the monitoring center (step 126), and thereafter, the process shifts to abnormality processing according to an instruction from the monitoring center. The monitoring center can recognize that there is a person in the monitoring building by receiving the set NG signal,
It is possible to take appropriate measures such as confirming whether the operator is a valid user.

In this embodiment, the security system in which the monitoring building and the remote monitoring center are connected by a telephone line has been described. However, the present invention is not limited to this. It is needless to say that the present invention is also applied to a security system in which is connected by a signal line.

[0038]

As described above, according to the present invention,
At a preset time, the building is automatically placed in the guard state, so even if you forget to put the building into the guard state, it will automatically go into the guard state, or the situation will be monitored by the monitoring center. So that you can understand and take appropriate actions,
The security of the monitored building is improved.

Further, even in a situation where the guarded building cannot be placed in a security state due to a threat of robbery or the like, the situation of the guarded building at the time when the guard should be set can be grasped by the monitoring center, so that prompt and appropriate measures can be taken. It is possible.

Further, even if the security set time comes, if the user does not perform the security set operation, it is possible to promptly respond at the monitoring center and eliminate the unguarded state. Becomes

Further, the security set time can be set and extended by the user, and the load on the monitoring center can be reduced.
