Description

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, etc., and more particularly to a security device having a function of automatically setting a security area in a security state according to a schedule. Further, the present invention relates to a security system constructed by such a security device and a central monitoring device in a monitoring center.

[0002]

2. Description of the Related Art Conventionally, various sensors such as an intrusion sensor and a fire sensor are used to connect to a monitoring center via a communication line such as a telephone line and to monitor the situation in a monitoring building such as an office building, a condominium or a detached house. There is known a security device which monitors and sends an abnormal signal to a monitoring center through a communication line when a sensor detects an abnormality.

[0003] These security devices are a security set that unlocks the intrusion sensor when a person is inside the building during the daytime, and activates the intrusion sensor when the inside of the building becomes unattended at night or on holidays. Set to. Because of this setting, it is common practice for the final exiter to operate a security set with a security device when leaving the surveillance building. At this time, if the last exiter forgets to operate the security set, there is a problem that the building is unguarded despite the fact that the surveillance building is unmanned. In order to solve this problem, there has been proposed a device which automatically becomes a guard set at a preset time (for example, Japanese Patent Laid-Open No. Hei 10-242242).
4-324597 publication).

[0004]

However, in these conventional security devices, when the preset security set scheduled time is reached, the surveillance building is automatically put in the security state.
Even if there is a survivor in the surveillance building, there is a possibility that the survivor will be automatically in a guarded state. In that case, the sensor detects the survivor as an intruder and reports an abnormality to the monitoring center. Then, in the surveillance center, as an intrusion abnormality, the emergency responder rushes to the surveillance building.

As described above, even if a residual person who is not an illegal intruder is detected, it becomes necessary to deal with it, which results in wasteful countermeasures. To prevent this,
Some voices and displays provide a security set, so a message prompting the user to leave the room is issued to prompt the user to leave the building. Even in this case, I can't see the message,
Or, for some reason, such as not hearing, a residual person who is not an illegal intruder may be detected and a useless report may be made.

Further, when the guard 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.

In addition, when the security monitoring set time of each monitoring building is stored in the central monitoring device and there is a monitoring building to which the security setting signal is not sent by that time, the monitoring building is left unprotected. It is said that the guards go to the surveillance building, check the situation, and operate the set.

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

However, when the number of buildings monitored by the monitoring center is large, there is a problem in that telephone contact and change operation of these at the monitoring center become very complicated.

In view of such circumstances, an object of the present invention is to prevent the security set operation from being performed even at the scheduled security set time, and to prevent the situation of the security area even if the security set operation is not performed. Another object of the present invention is to provide a security device with improved security by confirming and setting it in a security set. A further object of the present invention is to provide a security system including such a security device.

[0011]

The present invention employs the following technical configurations in order to achieve the above objects. That is, the security device according to the present invention is a security device that detects an abnormality such as an invasion act or a vandalism action that occurs in a security area and notifies the monitoring center, and a storage unit that stores a preset security set scheduled time zone. ,
A security device comprising: an operation unit capable of changing the security set scheduled time period stored in the storage unit by the security set scheduled time period.

According to the present invention, the security set scheduled time zone is a predetermined time zone including the security set scheduled time.

Further, according to the present invention, in a security device for detecting an abnormality such as an invasion act or a sabotage act that occurs in a security area and notifying the monitoring center, at least a security set operation and an extension operation are urged at a scheduled security set time. Display means for displaying a message, operating means for enabling the security setting operation and extension operation, and set signal sending means for sending a set signal to the monitoring center in response to the security setting operation in the operating means A security set scheduled time changing means for changing the security set scheduled time according to the extension operation in the operating means, and the security in the operating means within a predetermined time after displaying the message on the display means.

2 illustrates a signal processing unit that performs signal processing such as sending a signal to a security device via the communication control unit 16 and the communication control unit 16.

Next, with reference to the flow charts of FIGS. 3 and 4, a security set processing procedure of the security device of the present invention will be described.

First, it is assumed that the surveillance building is in a security-released state. In the signal processing unit 1, the current time from the clock unit 5 and the security set time preset in the storage unit 4 (specifically, including the time at which security is set, such as 17:50 to 18:10). It is also meant to include a predetermined time zone (“security set time zone”) (step 1)
02) If they match, a message that the security set time has come is displayed, and a message prompting the security set operation or the security set time change operation is displayed on the display unit 3 (step 104). The display unit 3 may be a liquid crystal display, a speaker, or the like as long as it can visually or auditorily notify the user that the security set time or a time slightly before the extended security set time has come. If it does not match the security set time, the comparison operation is continued until the preset security set time or the security set time extended by the change operation is reached.

After that, when the user sees the message on the display unit 3 and operates the security set from the operation unit 2 (YES in the determination of step 106), the signal is input to the signal processing unit 1 to set the security set. Then, the signal processing unit 1 notifies the security set signal to the central monitoring device 20 via the communication control unit 6 and the communication line 7 (Step 132). By receiving this set signal, the monitoring center can confirm that the monitored building has entered the alert state.

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

The security setting operation and extension operation are
It may be enabled only when the operator can confirm it with a D card or the like.

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

The central monitoring device 20 installed in 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
Displays the information of the surveillance building in which the security device that has issued the unset signal is installed from the storage unit 13, for example, the surveillance building name, and displays it on the display unit 12. By looking at this display, the controller in the surveillance center can confirm that the surveillance building, which should have been set with security, is not set with security.

The air traffic controller inquires of the surveillance building with such a display, for example, by telephone that the security start time is reached, and the like to judge the presence / absence of an appropriate user and the situation of the surveillance building. To explore.

If it is confirmed that there is a proper user, the user is asked to extend the security set scheduled time or operate the security set. Also, when the presence of an improper person such as a robbery is recognized, the guard is made to deal with it.

Thus, even in a situation where the user forgets the security set or is attacked by a robbery and cannot operate the security set or change the scheduled time of the security set, the monitoring center can grasp the state of the monitoring building. It becomes possible to take appropriate measures.

On the other hand, when the controller judges that there is no person in the surveillance building, it is highly possible that the user has forgotten the set operation and exited. If left unattended, the user remains unguarded. Therefore, the crime prevention 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 the present embodiment, even when the security set time is reached by the security device, it is not in the set state, and when the security set scheduled time is not extended, the security device sends an unset signal to the monitoring center. The central monitoring device 2
If 0 is set, the security set scheduled time of each security device is stored, and if the set signal or the extension signal of the security set scheduled time is not received from the corresponding security device at the relevant time, the unset signal is received. It may be automatically displayed on the display unit 12 even if there is not.

Thus, the signal processing unit 1 in the security device
Receives the automatic setting permission signal from the central monitoring device 20 which has received the unset signal via the communication line 7 and the communication control unit 6 (YES in the determination in step 114), to check the situation of the monitoring building. , It is checked whether the sensor 9 is in a normal state (step 116). When all the sensors 9 are in a normal state, that is, when no abnormality is detected, the process proceeds to step 120.

On the other hand, when the set permission signal is not transmitted from the monitoring center even though the communication line is normally connected, for example, when 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 checking the state of the sensor 9 in step 116, if there is no problem, the provisional set state is set in which all the sensors arranged in the surveillance building are in the surveillance state (step 120). However, if there is a problem such as the window being opened and the sensor being in the sensing state, state N
The G signal is sent from the communication control unit 6 to the monitoring center via the communication line 7 (step 118), and then the abnormality processing is instructed by the monitoring center. When this state NG signal is received by the central monitoring device 20, the monitoring center can recognize that it is at the scheduled security set time, is in an unmanned state, and is in a state in which doors are not locked, and some abnormal situation occurs. Therefore, it is possible to take measures such as giving instructions to emergency response personnel at the surveillance building.

When the surveillance building enters the temporary set state, that is, the temporary security state, the timer unit 10 is activated (step 12).
2). The time-up time of the timer unit 10 is a predetermined time, for example, 10 minutes, which can be used to judge whether or not a person remains in the surveillance building, or whether or not the person is out of the surveillance building for a short time. It is set in advance.

If the presence of a person cannot be confirmed while the timer unit 10 is operating, that is, if the sensor 9 for detecting the person present in the room does not detect the person (N in the determination in step 124).
O), when the timer unit 10 has timed out (YES in the determination in step 128), the security set is shifted to the security state (step 130), and a security set signal for notifying this is sent to the monitoring center (step S130). Step 132). By receiving this set signal, the monitoring center recognizes that the monitored building is in a guarded state.

On the other hand, if the sensor 9 detects a person while the timer unit 10 is being activated (YES in step 124).
S), the set NG signal is sent to the monitoring center (step 126), and then the abnormality processing is instructed by 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 for the operator to take appropriate measures such as confirming whether the operator is a legitimate user.

Although the security system in which the monitoring building and the remote monitoring center are connected by a telephone line has been described in the present embodiment, the present invention is not limited to this, and the monitoring area and the monitoring center in one building are not limited to this. It goes without saying that it 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 the preset time, the security status is automatically set, so even if you forget to put the building in the security status and leave it for a while, the security status is automatically set or the situation is monitored at the monitoring center. Because it will be possible to grasp and take appropriate measures,
The security of the surveillance building is improved.

Furthermore, even in a situation where the surveillance building cannot be put into the guarded state due to threats such as robbery, the situation of the surveillance building at the time when the guard should be set can be grasped at the surveillance center, so that prompt and appropriate measures can be taken. It will be possible.

If the security set operation is not performed by the user even at the scheduled security set time, it is possible to promptly respond at the monitoring center, and the unguarded state can be eliminated. Becomes

Further, the user can set and extend the security set time, and the load on the monitoring center is reduced.
