Abstract

PURPOSE:To quickly attain a suitable coping with gas interruption by connecting an external sensor interruption output operating an interruption valve, a transmission discrimination section receiving each internal sensor discrimination output and a gas supply center by means of telephone. CONSTITUTION:Outputs of a vibration sensor 7, a gas leakage alarm unit 8, a pressure sensor 9 or the like are detected by sensor output detections 1a-1c, an external sensor interruption discrimination section 2 outputs an interruption signal in response to a sensor output to operate a gas interruption valve 10 via an external sensor interruption control section 3. A sensor discrimination section 4 from outputs of the detection sections 1a-1c discriminates the sensor and a discrimination signal is supplied to a conduction discrimination section 5 receiving an interruption signal from the discrimination section 2. The discrimination section 5 is coupled with a gas supply center 11 via a transmission interface section 6 by telephone, the sensor discrimination output information being a cause to valve interruption is supplied to the center 11 in response to the call from the center 11 and the disposition after interruption is performed via the gas supply center quickly and properly in response to the cause to interruption.

A conventional gas cutoff device includes a sensor output detection section 1 that detects the output of an electric shocker, a gas leak alarm, or a pressure sensor and outputs a predetermined output signal, and a sensor output detection section 1 that receives an output signal from the sensor output detection section 1. , determines whether or not a predetermined condition is met, and if so, outputs an external sensor shutdown signal 'I!' receiving the external sensor cutoff signal;
It consisted of a cutoff control section 3 that outputs a cutoff signal to activate the cutoff cell.

In the above configuration, in the event of an earthquake, a seismic sensor and a gas leak
The sensor is a gas leak alarm, and when the gas pressure drops, the pressure sensor is activated, and the sensor output detection unit 1 detects the output of a sensor such as a seismic sensor, outputs a predetermined output signal, and the output signal is If predetermined conditions are met, an external sensor cutoff signal is output and a cutoff valve is activated.

Problems to be Solved by the Invention However, with the above configuration, the gas utility center does not immediately know that the gas cutoff device is shutting off the external sensor, and at the gas consumer, the cutoff valve operates and the gas is turned off. Due to a power outage, gas customers had to contact the gas utility center and then have a problem.

In addition, the gas utility center has been dealing with the problem of not being able to determine whether the external sensor was shut off due to a seismic sensor, a gas leak alarm, or a pressure sensor.

The present invention solves the above-mentioned problems by identifying the sensor that caused the external sensor combination, and reporting information on which sensor caused the external sensor to be shut off to the gas utility center using a telephone line, or It provides a callable gas cutoff device.

one or more sensor output detection sections, and an external device that determines whether or not the output signal from the sensor output detection section satisfies a predetermined condition, and outputs an external sensor cutoff signal if the predetermined condition is met. a sensor cutoff determination section; a cutoff control section that receives the external sensor cutoff signal and outputs a cutoff signal that activates the cutoff valve; and receives the output signal from the sensor output detection section and identifies which sensor output signal it is. j7,
a sensor identification unit that outputs the identification signal; a transmission determination unit that determines whether or not to transmit the identification signal based on the external sensor cutoff signal or the call signal from the gas utility center; transmitting a signal to the transmission determining unit, receiving the identification signal from the transmission determining unit, and configuring the identification signal into a predetermined message;
It consists of a transmission interface unit that sends out a message to a telephone line.

Effects The present invention produces the following effects due to the above-described configuration. It is possible to identify the sensor that caused the external sensor of the gas shut-off device to shut off, and to report or call the gas utility center using a telephone line with information on which sensor caused the external sensor to shut off.

Embodiment Below, a block diagram of an embodiment of the present invention is shown in FIG. This will be explained with reference to FIG.

Effects of the Invention As described above, according to the gas cutoff device of the present invention, the sensor that caused the external sensor cutoff is classified by FLJ, and information about which sensor caused the cutoff of the external sensor is transmitted to the gas business using a telephone line. By being able to report or call the gas utility center, the gas utility center can immediately know which sensor caused the external sensor shutoff at the gas consumer, which is very convenient and allows for immediate response. That is, for example, if it is known that an external sensor has been cut off by a seismic sensor, the earthquake disaster area can be understood and countermeasures can be easily taken. In addition, if external sensors are shut off using a gas leak alarm, individual responses to gas consumers can be taken promptly. If the external sensor is shut off using a pressure sensor, the area where the gas pressure has decreased can be limited and restoration can be carried out quickly.
