[0004]

The above-mentioned conventional intrusion monitoring device has the following problems. The intrusion monitoring device 100 transmits an alarm to the monitoring station 500 as described above when security is required at night or the like, but cancels security when there is a person at the security monitoring destination other than at night. Thus, the alarm is not transmitted to the monitoring station 500.

Therefore, if an abnormality occurs in the intrusion sensor 200 while the security is released and the security is started without performing the inspection, a period in which the intrusion sensor 200 does not operate normally occurs. Therefore, the intrusion monitoring device 1
00 cannot be effectively guarded.

[0021]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a security terminal system according to an embodiment of the present invention.

The security terminal system 10 comprises a magnet sensor 20 for detecting the presence or absence of intrusion and outputting a detection signal, and a terminal device 30 for monitoring the presence or absence of intrusion based on the detection signal output from the magnet sensor 20. It is remotely connected to a security monitoring center (not shown) via a communication line. With this configuration, when an intrusion occurs, the magnet sensor 20 operates to output a detection signal indicating that the intrusion has occurred. Then, the terminal device 30 detects this intrusion based on the detection signal and notifies the security monitoring center via the communication line.

The magnet sensor 20 is composed of a magnetism generator 21 arranged on a window or a door and a magnetism detector 22 arranged on a frame such as the window or a door. With such a configuration, when the window or the door is closed, the magnetic detection unit 22 detects the magnetism generated from the magnetic generation unit 21 and outputs a normal signal (make contact), and the window or the door is open. In this case, the magnetism detection unit 22 cannot detect the magnetism and outputs an abnormal signal (break contact).

The magnetism generating unit 21 includes power supply terminals 21a, 21a connected to the terminal device 30,
An electromagnet 21b is operated by a power supplied from the terminal device 30 via the power supply terminals 1a and 21a.
When the power supply is stopped, the generation of magnetism from the electromagnet 21b stops.

The magnetism detecting section 22 comprises a reed switch 22a which operates according to the presence or absence of magnetism, and output terminals 22b, 22b connected to the terminal device 30.
b, the reed switch 22a
Operates to output a normal signal to the output terminals 22b and 22b, and unless the magnetism is detected, the reed switch 22a does not operate and outputs an abnormal signal to the output terminals 22b and 22b.

Therefore, the magnet sensor 20 that detects the presence or absence of intrusion and outputs a detection signal constitutes an intrusion sensor in this sense. The terminal device 30 includes the magnet sensor 2
Sensor power control unit 31 for turning on / off the power supply to power supply 0
A sensor operation detection unit 32 that constantly monitors the operation of the magnet sensor 20 and outputs an operation signal based on the operation, and a security state setting unit 33 that outputs a setting signal for setting start and release of security. , A network control unit 34 connected to the security monitoring center via a communication line, and a control unit 35 for controlling these parts.

With this configuration, when the user performs a security start operation in the security status setting unit 33, the security status setting unit 3
3 outputs a security start signal to the control unit 35. Then, the control unit 35 instructs the sensor power control unit 31 to perform an inspection operation of the magnet sensor 20 and starts a security state when confirming that the magnet sensor 20 operates normally. If there is an intrusion, an operation signal indicating that there is an intrusion is input to the control unit 35 via the sensor operation detection unit 32, and the control unit 35 informs the security monitoring center via the network control unit 34 that the intrusion has occurred. Send the indicated intrusion alert.

On the other hand, when the user performs a security release operation at the security state setting unit 33, a security release signal is output from the security state setting unit 33 to the control unit 35. Then, the control unit 3
5 instructs the network control unit 34 not to transmit the intrusion alarm to the security monitoring center. Therefore, even if there is an intrusion in the security released state, an intrusion alarm is not transmitted to the security monitoring center.

FIG. 2 is a flowchart showing the operation of the terminal device when security is started. Sensor power controller 3
1 is disposed between the control unit 35 and the power connection terminals 21a, 21a, and turns on / off the power supply to the electromagnet 21b according to an instruction from the control unit 35. Sensor operation detector 32
Is disposed between the control unit 35 and the output terminals 22b, 22b, and outputs an operation signal to the control unit 35 based on a normal signal or an abnormal signal output from the output terminals 22b, 22b. The security state setting unit 33 includes a security start button and a security release button (not shown), and is connected to the control unit 35. With this configuration, when the user depresses the security start button, a security start signal is output to the control unit 35 (Step S100). At this time, the control unit 35 instructs the sensor power control unit 31 to turn off the power to the electromagnet 21b (step S110). The power supply to the electromagnet 21b is always on, and is temporarily turned off only when a setting signal to start security is output from the security state setting unit 33. For this reason, even if there is no actual intrusion, the magnetism generated by the electromagnet 21b disappears, which means that there is a pseudo intrusion.

Accordingly, an abnormal signal is output from the reed switch 22a to the sensor operation detecting section 32 via the output terminals 22b, 22b (step S120). The sensor operation detection unit 32 outputs an operation signal based on the abnormal signal to the control unit 3.
5, the control unit 35 controls the magnet sensor 20
Is determined to be operating normally and security starts (step S130).

On the other hand, when the above-described pseudo intrusion occurs, if the magnet sensor 20 is out of order or if the obstruction processing or the like is being performed, the reed switch 22 a
Since it is not possible to detect that the magnetism generated from 1b has disappeared, a normal signal is output to the sensor operation detection unit 32 via the output terminals 22b and 22b. Therefore, when the sensor operation detecting unit 32 outputs an operation signal to the control unit 35 based on the normal signal, the control unit 35 determines that the magnet sensor 20 has an abnormality, and sends the magnet sensor An abnormality alarm indicating that there is an abnormality is transmitted to the security monitoring center (step S140).

In the present embodiment, the abnormal alarm is transmitted to the security monitoring center. However, as shown in FIG.
It is also possible to connect the display unit 36 to the terminal 5 and display the abnormality alarm on the security terminal system 10 side. Network control unit 34
Has a DSU (not shown), creates transmission data based on the intrusion alarm or the abnormal alarm, and transmits the data to a security monitoring center via a communication line. In this case, the security terminal system and the security monitoring center are connected by a digital line such as the Internet or CATV, but any configuration capable of transmitting at least each alarm may be used. It can also be transmitted by radio such as radio waves.

The control unit 35 is constituted by a microcomputer (not shown) or the like, and performs control related to the above-described inspection operation at the time of starting security and control related to transmission of each alarm. Control unit 3
5 are executed by the CPU 3 as shown in FIG.
It is also possible to activate and execute the intrusion monitoring control program recorded in the ROM 38 connected to the PC 7. Accordingly, a sensor operation detection unit 32 that constantly monitors the operation of the magnet sensor 20 and outputs an operation signal based on the operation, a control unit 35 that transmits an intrusion alarm when the operation signal is input, The network control unit 34 that creates transmission data based on the transmission data and transmits the transmission data via a communication line, and the security monitoring center that receives the transmission data constitute intrusion monitoring means in this sense.

In addition, the magnet sensor 20
Power supply controller 3 for temporarily stopping power supply to the sensor
1, a sensor operation detection unit 32 that outputs an operation signal based on a normal signal or an abnormal signal output from the magnet sensor 20, and a check operation of the magnet sensor 20, and based on an operation signal obtained by the check. The control unit 35 that checks whether or not the magnet sensor 20 has an abnormality constitutes a test operation unit in this sense.

Further, a security state setting section 33 for outputting a setting signal for setting start and release of security, and a control section 35 for confirming that the magnet sensor 20 is normal.
In this sense, the network control unit 34 that connects the communication line and the control unit 35 in the security state and does not connect the communication line and the control unit 35 in the security release state constitutes a monitoring control unit in this sense. In the above-described inspection operation, the operation inspection of the intrusion sensor can be performed when the window, the door, or the like is closed at the start of security. That is, since the windows and doors are closed, the normal signal output from the magnet sensor 20 is transmitted to the electromagnet 21b.
By stopping the power supply to the power supply, it is possible to confirm that the magnet sensor 20 operates normally by changing to an abnormal signal.
On the other hand, if the normal signal output from the magnet sensor 20 at this time does not directly change to an abnormal signal, it can be confirmed that the magnet sensor 20 has an abnormality.

As shown in FIG. 5, an infrared sensor 40 can be used as an example of a configuration in which the open / close state of the windows and doors at the start of security does not matter. According to the figure, the security terminal system 10 includes an infrared sensor 40 that detects the presence or absence of intrusion and outputs a detection signal, and a terminal device that monitors the presence or absence of intrusion based on the detection signal output from the infrared sensor 40. 30 and is remotely connected to a security monitoring center (not shown) via a communication line as in the case described above. With this configuration, when an intrusion occurs, the infrared sensor 40 operates to output a detection signal indicating that the intrusion has occurred. Then, the terminal device 30 detects this intrusion based on the detection signal and notifies the security monitoring center via the communication line.

An infrared sensor 40 is disposed on an outer wall or the like and emits infrared light. A light receiving unit is disposed on the outer wall or the like so as to face the light emitting unit 41 and receives the infrared light. 42. With this configuration, when there is no intruder or the like, the light receiving unit 42 receives the infrared light emitted from the light emitting unit 41 and outputs a normal signal (make contact). 42 cannot receive the infrared light emitted from the light emitting unit 41 and outputs an abnormal signal (break contact).

The light emitting section 41 includes power connection terminals 41a, 41a connected to the terminal device 30, and the power connection terminals 41a.
a, an infrared light emitting unit 41b that emits infrared light by power supplied from the terminal device 30 via the power supply terminal 41a. When power is supplied through the power supply connection terminals 41a, 41a, infrared light is emitted from the infrared light emitting unit 41b. It emits light, and when the power supply is stopped, the emission of infrared light from the infrared light emitting unit 41b is stopped. The light receiving unit 42 includes an infrared light receiving unit 42a that detects infrared light, output terminals 42b and 42b connected to the terminal device 30, an infrared light receiving unit 42a and an output terminal 42.
b, 42b, and a relay 42c. When the infrared receiving section 42a detects infrared light emitted from the infrared emitting section 41b, it activates the relay 42c to send a normal signal to the output terminals 42b, 42b. Output, and if the infrared light is not detected, the relay 42c is not activated and the output terminal 42
b, 42b to output an abnormal signal.

As in the case described above, when the user performs a security start operation, the infrared sensor 40 is checked, and if the infrared sensor 40 is abnormal, an abnormal alarm is transmitted to the security monitoring center. Also, if there is an intruder in security,
An intrusion alarm is also sent to the security monitoring center.

Next, the operation of the security terminal system according to this embodiment will be described. When the user depresses the security start button, a security start signal is output to the control unit 35 (Step S100). At this time, the control unit 35 instructs the sensor power control unit 31 to turn off the power to the electromagnet 21b (step S110). Then, the power supply to the electromagnet 21b is stopped, and pseudo intrusion occurs. Therefore, when the reed switch 22a is normal,
An abnormal signal is output from a through the output terminals 22b, 22b to the sensor operation detection unit 32 (step S120).
When the sensor operation detection unit 32 outputs an operation signal to the control unit 35 based on the abnormal signal, the control unit 35 determines that the magnet sensor 20 is operating normally and starts security (step S130). ).

On the other hand, if the magnet sensor 20 is out of order or has undergone interference processing, a normal signal is output via the output terminals 22b and 22b without any change even if the magnetism generated by the electromagnet 21b is lost. 32. Therefore, when the sensor operation detection unit 32 outputs an operation signal to the control unit 35 based on the normal signal, the control unit 35 determines that the magnet sensor 20 has an abnormality,
An abnormal alarm is transmitted to the security monitoring center via the network control unit 34 (step S140).

When the vehicle enters the normal security state, if there is an intrusion, an operation signal indicating that there is an intrusion is output to the control unit 35 via the sensor operation detection unit 32, and the control unit 35
Transmits an intrusion alarm to the security monitoring center via the network control unit 34. When the user depresses the security release button, a security release signal is output from the security state setting unit 33 to the control unit 35. Then, the control unit 35 instructs the network control unit 34 not to transmit the intrusion alarm to the security monitoring center. Therefore, even if there is an intrusion in the security released state, an intrusion alarm is not transmitted to the security monitoring center.

As described above, when the user starts the security, the security terminal system 10 confirms that there is no abnormality in the magnet sensor 20 in the inspection operation and starts the security state.
Since the normally operating magnet sensor 20 can detect the presence or absence of the intrusion and can monitor the presence or absence of the intrusion,
Security can be effectively performed.
