Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a wide area monitoring system that uses telephone lines to monitor the occurrence of abnormal situations.

(Background technology) This type of wide-area monitoring system connects one or more transmitters and a specific receiver via a telephone line, and connects one or more transmitters with a specific receiver through a telephone line, and uses the transmitter side to detect disaster prevention sensors, crime prevention sensors, etc. The information is automatically sent to the receiver through the telephone line, and the receiver receives this information and issues an alarm.

It is configured to display.

By the way, when implementing such a system with a single line, if the transmitter receives an abnormal signal and then notifies the receiver, and there is no supervisor on the receiver side, the system will not function as intended. become unable to do so. Conventionally, in such a case, the abnormal signal received from the transmitter is transferred to another system by a contact output or the like, and the data of the abnormal signal is transferred from the other system to another receiver.

However, when the receiver receives an abnormal signal, transferring the abnormal signal to another system using the contact output and operating the other system complicates the system system, and it is difficult to take sufficient measures in an emergency. There are problems such as:

[Purpose of the invention]

The present invention was proposed in order to solve the problem of ridges, and the telephone line required for the receiver itself can be configured with a single line. It is an object of the present invention to provide a monitoring system configured to automatically transfer abnormal signals to other receiving means.

[Disclosure of the Invention] The system of the present invention proposed to achieve the above object is as follows:
Monitoring in which the abnormal signal from the abnormality detection means is taken into the transmitter and latched, and then the transmitter and receiver are connected via a telephone line, and the abnormal signal is transferred from the transmitter to the receiver. Regarding the system improvement, the above receiver has an automatic call receiving and automatic forwarding function, and when it receives an abnormal signal from the above transmitter, it activates an alarm means and within a specified time set in advance for the alarm means. The present invention is characterized in that when the deactivation signal is not input, the abnormality signal is transmitted from the receiver to another preset receiving means.

In such a system of the present invention, the receiving means to which the abnormal signal is transferred from the receiver has an automatic call receiving function, and is equipped with a separate monitor capable of issuing the same alarm as the receiver and displaying necessary information. In addition to receivers placed at locations, a paging device such as a pager or the like can be used by the absent supervisor.

Transmitter A and receiver aB are connected via a telephone office and telephone line 3, transmitter A has an automatic calling function, and receiver B has automatic call originating/receiving and automatic forwarding functions.

Transmitter A includes a heat sensor that transmitter A monitors.

Disaster prevention sensors such as smoke detectors and gas detectors, crime prevention switches, etc. are connected via fire alarm receivers, gas leak receivers, crime prevention receivers, etc., and when these sensors detect an abnormality, the transmitter A receives this, latches the abnormal signal, flashes the corresponding display lamp provided on the individual display section, and simultaneously sounds an alarm buzzer.

The flashing of the display lamp and the sounding of the alarm buzzer continue for a preset period of time until recovery is performed.

Furthermore, the transmitter A has an external switch C that is linked to the sensor, and the alarm buzzer stops ringing even when an abnormal signal is generated from the sensor in response to the set or reset operation of the external switch C. Can be done.

Such an external switch C is used in conjunction with a crime prevention sensor, for example, and is set to the set state at night when a supervisor is absent, thereby creating a crime prevention alert system that immediately reports an abnormal signal when the crime prevention sensor generates an alarm. By setting the system to the 7) state during the daytime when the security sensor is activated and a supervisor is present, the crime prevention alert system can be canceled without reporting an abnormal signal even if the crime prevention sensor generates an alarm.

In the latter case, the alarm from the security sensor is recorded even during daytime reset, and the display lamp provided on the corresponding individual display section flashes.

The system of the present invention is characterized by the operation of the receiver B shown in Fig. 7, and the transmitter A has an automatic transmission function and has a simple operation as shown in Fig. 6. In order to simplify the explanation, the operation will be explained using this case as an example.

When an abnormal signal is sent from the sensor on the transmitter A side, transmitter A launches the abnormal signal, flashes the lamp 1b of the individual display section 1a corresponding to the sensor, and at the same time sounds the alarm buzzer IC. Notify that an abnormal situation has occurred (steps 1001 and 1002). At the same time, use its own automatic calling function to dial and call receiver B, connect telephone line 3, and transmit the abnormal signal. do(
Steps 1003 to 1005) After the transfer of the abnormal signal is completed, when receiver B confirms that the abnormal signal has been received, the telephone line is opened (step 1006).
Transmission 8 transferred to B! A notifies the occurrence of an abnormal situation by sounding the alarm buzzer 1c until the situation is restored or for a preset time.

In response to such a transmission@A operation, receiver B sets the code number of the destination receiving means in advance to determine whether to transfer to another receiver or to call by pager, and A designated buzzer ringing time TB is set (steps 2001 and 2002). Receiver B confirms the arrival of the abnormal signal, connects the line, and receives the abnormal signal. When the reception is completed, the display lamp 2b flashes and the alarm buzzer 2c simultaneously sounds (steps 2003 to 2007). )
.

At this time, at the same time, a buzzer timer (not shown) provided on the receiver B side is driven to start counting the timer (step 2008).

In step 2009, it is determined whether the timer count value Tb has reached the specified time TB.

Before the buzzer timer reaches the specified time TH, the supervisor performs an operation to stop the buzzer sounding (step 2010)
Then, proceeding to step 2011, the alarm buzzer that was sounding
Although the IC is stopped, the alarm buzzer IC's stop switch is not pressed and the timer counts (when iTb reaches TB, step 2009), the process proceeds to step 2012, the code number set in step 2001 is referenced, and the reception It is determined whether aB has set receiver B' as a transfer destination.

If receiver B has set receiver B' as the transfer destination, the process advances to step 2013 and transfers the call to another receiver B', and when the other receiver B' confirms the call, an abnormal signal is sent. Data related to this will be transferred.

However, in step 2012, if there is no transfer command, that is, if the transfer destination receiver has not been set, the process proceeds to step 2015 and a call is made to the pager.

〔Effect of the invention〕

As can be understood from the above explanation, according to the system of the present invention, the trouble of having a supervisor constantly present at the receiver side to monitor the receiver can be eliminated, and the supervisor can use a portable device such as a pager to monitor the receiver. By simply carrying a paging device, you can monitor abnormalities while working on other tasks. In addition, if the supervisor is away, you can set another receiver as the forwarding destination and the receiver can forward the message to a central monitoring center, etc., allowing efficient operation on the receiver side. I can figure it out.
