Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a crime prevention monitoring device that can reduce security gaps in a mechanical security system.

In conventional security monitoring devices, users of the security monitoring devices in offices, stores, factories, etc. are provided with security detectors and security start/release keys that can be directly operated by security monitoring centers (hereinafter referred to as security centers). They are connected via communication lines. However, in order to operate the security start/cancel key, for example, close to a door or window, the key must be opened/closed in order to confirm the status of the security sensor and then turn the key ON (warning). The security detector installed to detect the state will remain in an alarm state when the doors and windows are open when security starts, and the security start/cancel key will be turned on (alert). As a result, the entire security area becomes unguarded. Therefore, in the past, in order to prevent this type of erroneous operation alarm, measures have been taken to send an erroneous operation signal to the security center, but in the end, the user turned on the security start/cancel key. Users who were unfamiliar with the building's floor plan or the location of the security detectors were asked to leave the building alone or contact the security center. There were times when there was a gap in security due to people leaving the building alone. Additionally, when leaving the facility late, many flJs leave without operating the security start/release key at all, posing a security problem.

The present invention has been made in order to improve the above-mentioned drawbacks.The present invention has been made in order to improve the above-mentioned drawbacks. By operating the security start/cancel key and turning it on (alert), it is a security monitoring device that can reduce the security situation caused by erroneous operation by the user, that is, the security situation.
- intended to provide.

Hereinafter, two embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention, in which:
1 is a security start/cancellation key, 2 is a security detector that detects abnormal conditions such as intrusion and issues an alarm signal, and 3 is the security start/cancellation key.
It is connected to the release key 1 and the security detector 2, and the security start/
Based on the order of generation of the security start signal from the operation of the release key 1 and the security signals from the security detectors 2 provided in each security area divided into a plurality of areas, if the latter comes before the former, it is determined to be an erroneous operation, and this is detected. An erroneous operation detection section outputs an erroneous operation signal 3a upon detection; 4 is an attention-calling section consisting of a buzzer, a lamp, etc.; 5 is a warning section 4' that receives the erroneous operation signal 3a output from the erroneous operation detection section 3; 6 is an area selection section connected to the security start/cancel key 1, the security detector 2, and the erroneous operation detection section 3, and receives an erroneous operation signal 3a from the erroneous operation detection section 3.
When the alarm signal from the security sensor 2 is input, the security sensor i including the security sensor 2 that is emitting the alarm signal is suspended.
An abnormal state such as an intrusion is detected and an alarm is issued by the security sensor 2 belonging to the security area that is not selected after that, or by the security sensor 2 when the above-mentioned erroneous operation signal 3a is not input. When the signal is issued, the area selection unit 6 is configured to output an alarm signal 6a in response to the signal.

Reference numeral 7 denotes a communication control unit connected to the area selection unit 6 and the erroneous operation detection unit 3, which inputs the alarm signal 6a and the erroneous operation signal 3a and controls to send both signals 6a, 3a to a security center (not shown). is configured to do so.

In the crime prevention monitoring device according to the embodiment of the present invention having the above configuration, first, the user of the device issues a security start signal by setting the security start/release key 1 to the ON (warning) state. When output, if none of the security detectors 2 is emitting an alarm signal, the erroneous operation detection section 3 does not detect an erroneous operation and does not output the erroneous operation signal 3a.Therefore, the area selection section 6 inputs the erroneous operation signal 3a. Since there is no
When any of the security window chillers 2 detects an abnormal state such as an intrusion and outputs an alarm signal, the alarm signal is input.If the user has already issued an alarm signal due to an erroneous operation, the erroneous operation detection unit 3 Detecting the erroneous operation, the erroneous operation signal 3a is output, and the caution protrusion drive section 5 that receives the signal 3a generates a buzzer,
A warning unit 4 such as a lamp is activated to issue an alarm and call the person's attention.

At the same time, the area selection unit 6 which has received the erroneous operation signal 3a suspends the alarm signal from the security sensor 2, selects the security area including the security sensor 2 that is emitting the alarm signal, and selects the area after that. When a security sensor belonging to a security area that is not protected detects an abnormal condition such as an intrusion and issues an alarm signal, the area selection section 6 inputs this and sends out an alarm signal 6a to the communication control section 7. When the communication control unit 7 receives the erroneous operation signal 3a from the erroneous operation detection unit 3, it first sends it to a security center (not shown), and then sends the alarm signal 6ak from the area selection unit 6 to the alarm center. control to send to.

As described above, according to an embodiment of the present invention, even if the user performs an incorrect operation due to carelessness, an alarm such as a lamp or buzzer will prompt the user to perform the operation again, and even if the user neglects to perform the operation again, Since the entire security area is not left unguarded and the security center can be notified that the security is incomplete, the reliability of the mechanical security system can be significantly improved.

FIG. 2 shows another embodiment of the present invention, in which the same reference numerals as in FIG. 1 indicate the same parts or similar parts,
I will omit the detailed explanation.

In the figure, 8 is a timer that outputs a security start signal at a preset time, 9 is an input terminal for inputting the output signal of the timer 8, and another input terminal for inputting the output signal of the security start/cancellation key 1. This is an OR dart that takes the logical sum and outputs it to the erroneous operation detection section 3 and area selection section 6.

In the crime prevention monitoring device according to another embodiment of the present invention having the above configuration, when the user leaves the building, the security start/release key 1 is pressed.
When any of the security detectors 2 issues an alarm signal, the area selection unit 6 selects the security signal 6a.
An alarm signal is transmitted to a security center (not shown) via the communication control unit 7. On the other hand, if the user neglects the operation and leaves the building, the timer 8 starts at a preset time and outputs a security start signal via the OR gate 9. From now on, when any of the security sensors 2 issues an alarm signal, the alarm signal is output to the security center according to the manual key operation procedure. However, if any of the security detectors 2 has already issued an alarm signal by the time the timer 8 is activated and the security start signal is output, the erroneous operation detection unit 3 detects an abnormality in the start of security and sends an abnormal security signal. 3a is transmitted to the security center via the communication control unit 7. At the same time, the area selection unit 6 suspends the alarm signal from the security sensor 2, selects the security area that includes the security sensor 2 that is emitting the alarm signal, and belongs to the security area that cannot be selected thereafter. When the security detector 2 detects an abnormal condition such as an intrusion and issues an alarm signal, an alarm (IF No. 6a
is sent to the security center via the communication control unit 7.

As described above, in other embodiments of the present invention, even if the user neglects to operate the security start/release key, security is reliably implemented by using a timer, etc., and even if the security is not fully implemented, teeth,
The security center is automatically notified that the set is abnormal.

As explained above, according to the present invention, by dividing a security area into a plurality of security areas and providing an erroneous operation detection means and an area selection means, even if the security start operation is incomplete, the security detector can Turn on security areas that are not emitting alarm signals
As a result, the reliability and reliability of the mechanical security system can be significantly improved, which is a great practical effect.
