It is.

[Conventional technology]

2. Description of the Related Art Conventionally, there has been proposed a mechanical security device that sends a warning signal to a monitoring center through an information transmission device disposed at a security destination when a sensor installed on a security target detects an abnormality.

[Problems to be solved by the invention]

In a conventional machine security device, when a monitoring center receives an alarm signal output from a security target, the monitoring center informs a security guard who is patroling nearby and hasten the security destination. When a security guard who goes to the site enters the premises of the security destination and checks for an alarm and finds any abnormality, a nearby public telephone, a wireless communication device mounted on a security vehicle or Using a mobile cellular phone or the like, the monitoring center is first notified, and the monitoring center notifies the police, fire department, and other public institutions of the occurrence of an abnormal situation. Since promptness is required for reporting to the monitoring center, if an abnormal situation is discovered at a security location, it is desirable that there be public telephones available immediately in the vicinity. It is not always easy for security guards to memorize the position of a public telephone, and when a public telephone is used by a third party, the public telephone cannot be used as a reporting means. In addition, when a guard goes by car to a security destination where a warning has been issued, stopping the vehicle near the security destination may cause the criminal to notice and escape, and in order to avoid the risk of getting caught in a fire, Security guards are forced to stop the vehicle at a certain distance from the guarded building.Therefore, in an emergency, the vehicle returns to the vehicle equipped with the wireless communication device and reports to the monitoring center from the vehicle. If you do,
In the meantime, there has been a problem that a criminal (intruder) escapes or in the case of a disaster such as a fire, the damage is further increased, and it becomes impossible to minimize the damage. Also,
Even if the security guard has a small mobile phone,
In a special situation where the guards are injured due to the criminal's resistance (when the guards cannot communicate by voice), there is a problem that the guards cannot be used.

Therefore, the present invention has been made in view of such problems of the prior art, and the purpose of the present invention is to make sure that a security officer dispatched in the event of an emergency checks the authenticity of the police before the police Another object of the present invention is to provide a mechanical security device that can greatly shorten the time required to notify a monitoring center when it is necessary to request a public agency such as a fire department to dispatch.

Another object of the present invention is that the monitoring state is in the security mode,
When the sensor issues a detection signal, the system automatically switches to the alert mode, and the report request signal is transmitted to the monitoring center only in this alert mode, and the report request signal is erroneously transmitted to the monitoring center. Output is extremely low, and the monitoring center can make a request to dispatch to the police, fire departments, and other public agencies without hesitation when receiving a report request signal from a security guard, and it is possible to minimize damage It is an object to provide a simple mechanical security device.

〔Example〕

(Configuration of Embodiment) FIG. 1 is a block diagram showing a functional configuration of the present invention, and FIG.
The figure is a block diagram of the transmitting means constituting the present invention.

In these figures, the mechanical security device A according to the present invention is shown.
Means that a fire, intrusion,
A sensor group 1 consisting of a desired number of sensors 1 ₁ , 1 ₂ ,... 1 _n installed at an appropriate place to be guarded to detect an abnormal situation such as a gas leak, and a detection signal from the sensor group 1 Is received, an alarm display means 2 for displaying the type, location, and the like in a visible and audible manner, a mode changeover switch 4 for switching a monitoring state between a security mode and a release mode, and a monitor connected to the police display means 2. when the state is in security mode, at least one sensor constituting the sensor group 1, for example 1 when ₁ detects an abnormality, transmitting means 3 for transmitting to the monitoring center via a communication line 8 a detection signal that the sensor outputs And a terminal 5 capable of outputting a signal requesting a report to a public agency such as a police or fire department to the transmitting means 3.

The terminal 5 includes the transmitting unit 6 and the receiving unit 7.
It is composed of The transmitting unit 6 is formed of a portable wireless communication device that has a push button (operator) and can be worn on a belt or the like of a guard. On the other hand, the receiving section 7 is formed by a receiver. Thus, when the push button of the transmitting unit 6 is pressed, a report request signal (contact signal) is transmitted from the antenna, and when the receiving unit 7 receives the report request signal, the transmitting unit 3 connected to the receiving unit 7 is transmitted. The notification request signal is transmitted to the monitoring center via the communication terminal.

The transmitting means 3 is connected to the receiving unit 7 and an AND gate 39.
And an encoding unit 32 which, when receiving a detection signal from the sensor group 1 and a report request signal from the receiving unit 7, encodes them and outputs the encoded signal to the communication processing unit 33. A communication processing unit 33 for transmitting an encoded signal to be transmitted to a monitoring center via a communication line;
D gates 34, 35, 39, an interface 36 connecting the mode changeover switch 4 and the AND gates 34, 35, or
It has a gate 37 and a timer 38 which is started when the monitoring state is in the security mode and at least one sensor constituting the sensor group 1 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, the report request signal for requesting a report to a public agency such as police, fire department or the like is generated by the encoding section.
32, output from the transmitting means 3 through the communication processing unit 33, and finally the report request signal is transmitted to the monitoring center through the communication line 8.

The mode changeover switch 4 is constituted by a key switch for switching a monitoring state to a security mode or a release mode. In the case of the release mode, the detection (alarm) signal is not transmitted to the monitoring center even if the sensor group 1 detects an abnormality (displayed on the display panel of the alarm display means 2 or sounds the sound device). Never.) On the other hand, at the time of leaving the office or at the end of work, the mode changeover switch 4 is operated to switch to the security mode. In this security mode state, when at least one sensor in the sensor group 1 detects an abnormal state, the transmitting means 3 issues an alarm signal. Is sent to the monitoring center. The monitoring center instructs security personnel who are waiting (or patrol) near the security destination to confirm the site. Furthermore, sensor when the security mode is the electronic security device, for example, 1 ₁ detects the abnormality, the time is to send an alarm signal to the monitoring center as described above, which is preset at the same time the timer 38, The security mode is the security mode. That is, since the sensor 1 ₁ and outputs a detection signal by detecting an abnormal situation in the security mode, the alarm mode until the predetermined time set by the timer 38 has elapsed. Then, in the alert mode, the monitoring center is set to be able to transmit a report request signal for requesting a public agency such as the police or fire department to be dispatched (see FIG. 3).

(Operation of Embodiment) Next, the operation of the embodiment will be described.

When the security staff switches from the release mode to the security mode by operating the mode change switch 4 when leaving the building B after work, a change signal is output from the mode change switch 4 to the transmission means 3. . Switching signal is interface
Via 36, it is supplied to one input terminal of each AND gate 34,35. Sensor 1 ₃₄ longer to one input terminal of the intrusion alarm system of the AND gate 34, the sensor 1 ₃₅ of fire alarm system is connected to another input terminal of the AND gate 35. Therefore, when for example the sensor 1 ₃₄ in this state senses an intruder detection signal to the other input terminal of the AND gate 34 is supplied, the detection signal from the output terminal of the AND gate 34 is output to the encoding unit 32 You. The detection signal is further transmitted as a warning signal to the monitoring sensor through the communication line 8 through the communication processing unit 33 (for this reason, the monitoring center urges the security personnel to the security destination, and the security personnel patrols the surroundings of the building B. If a spot is found in the building, such as a sign of intrusion, the monitoring center is notified to request that the police and the like be dispatched).

When in the security mode, for example, an intrusion alarm system sensor
1 When ₃₄ detects an abnormality and outputs a detection signal, there is an output from the output terminal of the AND gate 34 to the OR gate 37.
The timer 38 connected to the output terminal of the gate 37 starts, and outputs a time limit signal to one input terminal of the AND gate 39 for a predetermined time. In such a state, as described above, in response to a command from the monitoring center, a security guard arriving at the security destination inspects the area around building B while patrols, and finds evidence of intrusion into the building. When the push button of the terminal 5 being carried is pressed, a radio report request signal is issued, and when the receiving unit 7 receives the signal, the report request signal is transmitted to another AND gate 39 via the interface 31. It is supplied to the input terminal. Therefore, since there is an output from the output terminal of the AND gate 39 to the encoding unit 32, the report request signal is sent to the communication processing unit.
It is transmitted to the monitoring center via the communication line via 33. When the predetermined time has elapsed, the signal from the timer 38 is not input to one input terminal of the AND gate 39, so that the report request signal is not transmitted to the monitoring center even if the guard presses the push button.

If the security guard does not find any sign of intrusion into the building B when examining the surroundings of the building B, he operates the mode changeover switch 4 to change the monitoring state of the building B from the security mode to the release mode. Enters building B and investigates the cause of the alarm. In this case, there is a case where there is an intruder in the building B even though there is no sign of invading the building B. Therefore, the timer 38 is a predetermined time AND gate sensor 1 ₃₄ or sensor 1 ₃₆ fire alarm system of the intrusion alarm system after outputting a detection signal when the security mode regardless of the switching of the monitoring state
It keeps outputting a timed signal to 39, so that it is in the alert mode. In this regard, the time at which the timer 38 outputs the time limit signal (the time at which the alarm mode is set) is set, and after the sensor outputs the detection signal, the guard checks the surroundings of the building B and further investigates the cause of the alarm in the building B. When a security guard finds an intruder after entering the building B, pressing the push button of the terminal device 5 carried by the user as described above makes it possible to make a wireless notification as described above. A request signal is issued, and a report request signal can be transmitted to the monitoring center.

In the above embodiment, the terminal 5 requesting a report is an example of a wireless communication device carried by a security guard. Of course), for example, terminal devices may be installed at a plurality of places such as a gate post, a fence, and the like, and may be connected to the information transmission device with a wire.

〔The invention's effect〕

Since the present invention is configured as described above,
The following effects are obtained.

When an abnormality occurs in a security target and a security officer who has rushed to the site at the instruction of the monitoring center checks the truth of the abnormality and needs to request a dispatch from police, fire and other public institutions, It is extremely easy to notify the monitoring center of this fact, and the time can be greatly reduced, so that it is possible to avoid being evacuated by intruders and avoiding injuries to guards, and a highly reliable machine. A security device is obtained.

The system is automatically switched to the alert mode when the monitoring state is in the alert mode and the sensor emits a detection signal, and the notification request signal is transmitted to the monitoring center only in the alert mode. It is extremely unlikely that a report request signal will be output to the monitoring center by mistake. And the damage can be minimized.
