Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an alarm transmitting device, and particularly to an alarm transmitting device that transmits security information other than alarms.

[Conventional technology]

Conventionally, this type of alarm transmitting device sends security information sensed between sending out a security start signal and sending out a security release signal to a remote monitoring device. Furthermore, since it is necessary to constantly monitor fires, equipment abnormalities, etc., information is transmitted not only during the above-mentioned security period, but also outside of that period, that is, when the security is released, for 24-hour monitoring. As a result, the remote monitoring device was conducting regular monitoring while security was being released.

[Problem that the invention seeks to solve]

With the conventional alarm transmitting device described above, when the security is released, 2
Warnings that are not monitored for 4 hours Stop sending security alarms such as intrusion, theft, etc., so when patrolling a guarded destination, the guard is always turned off. For this reason, the remote monitoring device continues to monitor the security destination even when patrolling the security destination.

Therefore, there was a drawback that unless the patrol was notified in advance, it was not possible to tell whether the security light was in a deactivated state or was patrolling.

[Means for solving problems]

The alarm transmitting device of the present invention includes means for setting start and release of security, means for setting start and end of patrol, means for sensing a security signal during security or release of security, and The signals, security start and release signals, and patrol start and end signals are each stored as data,
and means for transmitting the security signal to a remote monitoring device via a communication line, and stopping the transmission of the security signal when the patrol start signal is generated.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

The figure is a block diagram showing the configuration of an embodiment according to the present invention.

In the figure, a network control unit 1 is connected to an exchange (not shown) via a telephone line a, performs automatic dialing to the exchange, and connects to a remote monitoring device. .

The security start/cancellation setting section 8 sets the security start mode.
Then, a security start signal 23 is given to the security information storage unit 6, and when the security release mode is set, a security release signal 24 is given to the security information storage unit 6.

The patrol start/end setting unit 10 provides a patrol start signal 25 to the security information storage unit 6 when the patrol start mode is set, and a patrol end signal 26 when the patrol end mode is set.

The sensing unit 9 senses alarms from sensors that detect alarms, and 24-hour monitoring information from sensors and emergency notification sensors that detect alarms that should be monitored 24 hours a day, such as the occurrence of a fire, and detects alarms corresponding to each alarm signal. Information 22 is output. Further, the sensing section 9 stops detecting the alarm by the alarm stop signal 32 when the security start/cancellation section 8 is in the security release mode. Also,: 1 When the tour start/end setting unit 10 is in the tour start mode, the all information stop signal 33 stops detection of alarm and 24-hour monitoring information.

The alarm storage unit 6 stores the sensing information 22 detected by the sensing unit 9, the security start signal 23 and security release signal 24 from the security start/cancellation unit 10, the patrol start signal 25 from the patrol start/end setting unit 10, and the patrol When the end signal 26 and the scheduled call recording signal 28 generated by the preferential call timer of the scheduled call generator 4 are given, they are stored as security information, and
A network control activation signal 30 is generated to connect to a remote monitoring device via a switch.

When the network control unit 1 is given the network control activation signal 30, it reads the telephone number information 20 from the telephone number setting unit 2 that stores the telephone number of the remote monitoring device, performs automatic dialing, and places a call to the exchange. conduct.

When connected to the remote monitoring device via the exchange, an incoming signal is received by the control signal receiving section 7 via the network control section 1.

When the control signal receiving section 7 receives the incoming signal, it generates an information transmission activation signal 34 and operates the line monitoring timer 11. Furthermore, when the transmission request signal is received, the circuit generates a line timer reset signal 36 to reset the line monitoring timer 11, and an information transmission activation signal instructing the information transmission section 5 to transmit security information. 34 is sent.

When activated by the information transmission activation signal 34, the information transmitting unit 5 receives the terminal number 21 from the terminal number setting unit 3, obtains security information from the security storage unit 6 via the security data bus 29, and then sends the information. The alarm information is edited into a pattern for transmitting the information and transmitted via the network control unit 1. When the alarm information is transmitted as shown in the diagram above, and the confirmation signal is sent from the remote monitoring device, the control signal is then transmitted. The receiving section 7 is
A confirmation signal is received via the network control unit 1, and a network control reset signal 27 is generated to open the line and notify the security information storage unit 6 that transmission has ended.

The line monitoring timer 11 overflows when no transmission request signal is received within a certain period of time, when an incoming signal is not received, or when a confirmation signal is not received. The security information storage unit 6 generates a signal 35, resets the control unit 1, releases the opening, and at the same time requests the security information storage unit 6 to retransmit the security information.
When a retransmission request is received by the network control activation request signal 30
is generated, and the above-mentioned alarm transmission operation is performed.

The scheduled transmission generator 4 generates a scheduled transmission signal 28 at regular intervals. The preferential call timer in the scheduled call generating section 4 is initialized by the preferential call timer reset signal 31 generated by the security information storage section 6 at the same timing as the network control activation request signal 30 is generated.

As described above, this embodiment includes a patrol start/end setting section 10 in addition to the security start/cancellation setting section 8, the sensing section 9, and the scheduled transmission generating section 4, which generate signals to be transmitted as security information. Therefore, information on the start and end of the patrol can be transmitted to inform the remote monitoring device that the patrol is underway, and during the patrol, the alarm detection of the sensing unit 9 is stopped to prevent unnecessary monitoring.

〔Effect of the invention〕

As explained above, the present invention allows the alarm transmitting device to distinguish between the start and end of patrol and the cancellation of guard start, and also to stop the alarm during patrol, thereby making the monitoring work of the remote monitoring device 111jl smooth and efficient. It has the effect of becoming.
