Abstract

PURPOSE:To shorten a communicating time to a monitoring center by activating a timer at the time of the detection of an abnormality, and transmitting a communication request signal to the monitoring center by operating a terminal equipment during the operation of the timer. CONSTITUTION:When a release mode is switched to a security mode after the end of the work of a staff at the destination of security, a switchover signal is outputted to a transmitting means 3. For example, when a sensor 134 detects the abnormality, and outputs a detection signal in the security mode, a timer 38 is activated, and a time limit signal is outputted to one input terminal of an AND gate 39 in a prescribed time. In this state, when the staff who arrives at the destination of security discovers the evidence of the intrusion into a building, and presses the press button of the terminal equipment, the communication request signal by radio is transmitted, and when a receiving part receives the signal, the request signal is supplies through an interface 31 to the other input terminal of the gate 39. Therefore, the communication request signal is outputted from the output terminal of the gate 39 to an encoding part 32, and transmitted through a communication processing part 33 to the monitoring center.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mechanical security device, and particularly to a mechanical security device that rushes to the scene based on instructions from a monitoring center when an alarm signal is output from a security target. staff will respond to the situation on-site.
Furthermore, the present invention relates to a mechanical security device that outputs a signal requesting a report to a monitoring center from a terminal carried by a security guard when it is necessary to report to a public institution such as the police or fire department.

[Conventional technology]

Conventionally, mechanical security devices have been proposed that, when a sensor installed on a security target detects an abnormality, send an alarm signal to a monitoring center through an information transmission device installed in a security light.

[Problem to be solved by the invention]

In conventional mechanical security devices, when the monitoring center receives an alarm signal output from the security target, the monitoring center
A security guard patrolling the area is contacted and dispatched to the security location. The security guard who went to the scene enters the premises where the security light is being used, checks the alarm, and if any abnormality is discovered, he or she calls a nearby public telephone, a wireless communication device installed in the security vehicle, or A mobile phone or the like is used to first notify a monitoring center, and then the monitoring center reports the occurrence of an abnormal situation to public institutions such as the police and fire department. Since reporting to the monitoring center requires promptness, it is desirable that there be a public phone nearby that can be used immediately if an abnormal situation is discovered at the security site. It is not always easy for security guards to remember the location of
Another problem is that if the public telephone is being used by a third party, the public telephone cannot be used as a means of reporting. Furthermore, when a security guard goes by vehicle to a security location where an alarm has been issued,
If the vehicle is parked near the building to be guarded, there is a risk that the criminal will notice and flee, and to avoid the risk of being caught in a fire, security guards usually park their vehicles at a certain distance from the building they are guarding. Therefore, in the event of an emergency, if you return to a vehicle equipped with a wireless communication device and report to the monitoring center from the vehicle, the criminal (intruder) may escape during that time. However, in the case of a disaster such as a fire, the damage is further amplified and it becomes impossible to minimize the damage. Furthermore, even if a security guard is in possession of a small mobile phone, in special situations where the security guard is injured due to resistance from the criminal (in a situation where the security guard cannot communicate by voice), it is practically impossible to use the mobile phone. There was a problem with it disappearing.

Therefore, the present invention has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to enable security guards dispatched in an emergency to confirm the authenticity of the information, and then To provide a mechanical security device that can greatly shorten the time required to notify a monitoring center when it is necessary to request public institutions such as the police and fire department to dispatch.

[Means to solve the problem]

The present invention includes a sensor group configured of a desired number of sensors that is installed on a security target to detect an abnormal situation, a mode changeover switch that switches the monitoring state between security mode and release mode, and When one of the sensors forming the sensor group detects an abnormality, a transmitting means transmits a detection signal outputted by the sensor as an alarm signal to a monitoring center, and the monitoring state is in security mode, and a timer that starts when at least one sensor forming the sensor group detects an abnormality; and a police officer;
and a terminal device capable of outputting a report request signal requesting a report to a fire department, etc. to the transmitting means, and by operating the terminal device while the timer is operating, the report request signal is transmitted via the transmitting means. This mechanical security device is characterized in that it is configured to be able to transmit data to a monitoring center.

[Function] If the terminal is operated while the monitoring status is in security mode and the timer that starts when at least one sensor in the sensor group detects an abnormality is operating, police, fire, etc. A report request signal requesting a report to a public institution is promptly transmitted to the monitoring center via the transmitting means and the communication line.

[Example] (Configuration of Example) FIG. 1 is a block diagram showing the functional configuration of the present invention, and FIG. 2 is a block diagram of a transmitting means constituting the present invention.

In the figure, the mechanical security device A according to the present invention is installed at an appropriate location of the security target in order to detect abnormal situations such as fire, intrusion, gas leak, etc. in the security target building (security target) B. Sensors ll, lx,...1. , an alarm display means 2 for displaying the type, location, etc. in a visible and audible manner when a detection signal from the sensor group 1 is received, and a monitoring state set to security mode and released. at least one sensor that is connected to the alarm display means 2 and that constitutes the sensor group 1 when the monitoring state is the security mode;
For example, when the sensor 11 detects an abnormality, the transmitting means 3 transmits a detection signal output by the sensor to the monitoring center through the communication line 8, and outputs a report request signal to public institutions such as the police and fire department to the transmitting means 3. It is equipped with a terminal device 5 that can be used.

Of these, the terminal device 5 is composed of a transmitting section 6 and a receiving section 7. The transmitter 6 is formed of a portable wireless communication device that is equipped with a push button (operator) and can be attached to a security guard's belt or the like. On the other hand, the receiving section 7 is formed by a receiver. In this way, when the push button of the transmitter 6 is pressed, a report request signal (contact signal) is transmitted from the antenna, and when the receiver 7 receives the report request signal, the report is sent via the transmitter 3 connected to the receiver 7. The request signal is sent to the monitoring center.

Further, the transmitting means 3 includes the receiving section 7 and the AND gate 39.
an encoding unit 32 that encodes the detection signal from the sensor group 1 and the report request signal from the reception unit 7 and outputs the encoded signal to the communication processing unit 33; , a communication processing unit 3 that transmits the encoded signal to be transmitted to the monitoring sensor via the communication line.
3, AND gates 34, 35, 39, an interface 36 connecting the mode changeover switch 4 and the AND gate 34, 35, and an OR gate 37 whose monitoring state is in security mode and which constitutes the sensor group 1. The timer 38 is activated when at least one sensor detects an abnormality. Thus, only when the push button provided on the transmitting section 6 of the terminal device 5 is pressed while the timer 38 is operating, a report request signal requesting a report to a public institution such as the police or fire department is sent to the encoding section. 32, Communication processing unit 3
The report request signal is output from the transmitting means 3 through the communication line 8, and is finally transmitted to the monitoring center through the communication line 8.

The mode changeover switch 4 is constituted by a key switch that changes the monitoring state to security mode or release mode. In the case of release mode, even if the sensor group 1 detects an abnormality, the detection (alarm) signal is not normally sent to the monitoring center (it is displayed on the display panel of the alarm display means 2, or the sound device is sounded). Never). On the other hand, when going out or at the end of work, the mode selector switch 4 is operated to switch to the security mode, and when at least one sensor in the sensor group 1 detects an abnormal state in this security mode, the transmitting means 3 sends an alarm signal. is sent to the monitoring center. The monitoring center instructs security guards who are on standby (or patrolling) near the security destination to check the scene. Furthermore, in this mechanical security device, when in the security mode, sensors such as 1. When detecting an abnormal situation, it transmits an alarm signal to the monitoring center as described above, but at the same time, the security mode becomes the alert mode for a period of time preset by the timer 38. That is,
The security mode is in the security mode from when the sensor 1 detects an abnormal situation and outputs a detection signal until the predetermined time set by the timer 38 has elapsed. In this alert mode, the monitoring center is placed in a state where it can transmit a report request signal requesting the dispatch of public institutions such as the police and fire department (see FIG. 3).

(Operation of example) Next, the operation of the embodiment will be explained.

When the employee at the security destination operates the mode changeover switch 4 to switch from the release mode to the security mode when leaving building B after finishing work, a changeover signal is output from the mode changeover switch 4 to the transmitting means 3. . Switching signal is interface 3
6 to one input terminal of each AND gate 34,35. Another input terminal of the AND gate 34 is connected to an intrusion alarm sensor 134, and another input terminal of the AND gate 35 is connected to a fire alarm system sensor 13. is connected. Therefore, in this state, for example, the sensor ts
4 detects an intruder, a detection signal is supplied to the other input terminal of the AND gate 34, and the detection signal is output from the output terminal of the AND gate 34 to the encoding section 32. The detection signal further passes through the communication processing unit 33 and is transmitted as an alarm signal to the monitoring center via the communication line 8 (for this reason,
At the monitoring center, a security guard is dispatched to the security location, and the guard visually inspects the surrounding area of building B while patrolling. If any abnormality is found in the building, such as evidence of an intrusion, the monitoring center requests the police, etc. to be dispatched. ).

When in security mode, for example, if the sensor 134 detects an abnormality and outputs a detection signal, the AND gate 34
Since there is an output from the output terminal of the OR gate 37, the OR
A timer 38 connected to the output terminal of the gate 37 is activated and outputs a time limit signal to one input terminal of the AND gate 39 for a predetermined period of time. In such a situation, as mentioned above,
Upon receiving instructions from the monitoring center, a security guard who arrives at the security location inspects the surrounding area of Building B while patrolling, and if he finds evidence of an intrusion into the building, presses the button on the terminal device 5 he is carrying. When pressed, a wireless report request signal is emitted, and when the receiving section 7 receives the signal, the report request signal is supplied to another input terminal of the AND gate 39 via the interface 31. Therefore, since there is an output from the output terminal of the AND gate 39 to the encoding section 32, the report request signal is transmitted to the monitoring center via the communication processing section 33 and the communication line. Furthermore, when the predetermined time has elapsed, AND
Since the signal from the timer 38 is not input to one input terminal of the gate 39, the report request signal is not sent to the monitoring center even if the security guard presses the button.

In the above embodiment, the terminal device 5 for requesting a report is a wireless communication device carried by a security guard. (important points), such as installing terminals at multiple locations such as gateposts and fences,
Of course, it may be connected to the information transmission device using a wire.

[Effects of the Invention] Since the present invention is configured as described above, it produces the effects described below.

An abnormality occurred in the security target, and the security guard rushed to the scene under instructions from the monitoring center. After confirming the authenticity of the abnormality,
When it is necessary to request the dispatch of public authorities such as the police or fire department, it is extremely easy to notify the monitoring center and it can also save time, allowing intruders to be exploited. A highly reliable mechanical security device can be obtained that can avoid escape or injury to the security guard.

In addition, when the monitoring state is in guard mode and the sensor emits a detection signal, the system automatically switches to guard mode, and the report request signal is sent to the monitoring center only in this guard mode. With this structure, it is extremely unlikely that a report request signal will be output to the monitoring center by mistake, and the monitoring center will not hesitate to dispatch a public agency such as the police or fire department when it receives a report request signal from a security guard. This makes it possible to minimize the damage.
