Abstract

PURPOSE:To operate a cut-off valve when a voltage is lowered below a defined value and notify a gas enterprise center of information on battery voltage drop utilizing a telephone circuit by detecting the battery voltage of a gas cut-off device. CONSTITUTION:The battery voltage of a gas cut-off device is detected by a battery voltage detecting pert 1, whether the voltage is below a defined value or not is judged by a voltage judging part 2 and, when below the defined value, a battery voltage drop signal is outputted. A cut-off control part 3 receives the battery voltage drop signal and operates a cut-off valve 6. At the same time, the battery voltage drop signal is formed into a defined telegraphic message by a transmission interface part 4 and sent out to a telephone circuit 5 to be transmitted to a gas enterprise center. Thereby, the gas enterprise center can be instantly notified of information on battery voltage drop, and can take a countermeasure rapidly, securing safety.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for monitoring the battery voltage of a gas cutoff device and transmitting information on the battery voltage to a gas utility center.

2. Description of the Related Art A conventional gas cutoff device is shown in FIG. This will be explained below with reference to the drawings.

The battery voltage of the gas cutoff device is detected by a battery voltage detection unit 1, and a voltage determination unit 2 determines whether or not the battery voltage is below a predetermined value.If the battery voltage is below a predetermined value, a battery voltage drop signal is issued. It will be done. Then, the cutoff control unit 3 receives the battery voltage drop signal and outputs a cutoff signal to operate the cutoff valve 6.

As described above, when the battery voltage falls below a predetermined value, the shutoff valve 6 is operated to stop the flow of gas.

Problems to be Solved by the Invention However, with the above configuration, it is difficult for the gas utility center to determine whether the battery voltage of the gas cutoff device has fallen below a predetermined value.
When the gas consumer operates the shutoff valve 6 and stops the gas supply, there is a problem in that the gas consumer only finds out after contacting the gas utility center.

In view of the above-mentioned problems, the present invention has been devised so that when the battery voltage is below a predetermined value, information on the battery voltage drop is sent to the gas utility using a telephone line, so that the gas utility center can immediately detect the battery voltage. The present invention provides a battery voltage monitoring device for a gas cutoff device that can detect a voltage drop and allow the gas utility center to take immediate action.

Means for Solving the Problems In order to solve the above problems, a battery voltage monitoring device for a gas cutoff device according to the present invention includes a battery voltage detection section that detects the battery voltage of the gas cutoff device; A voltage determination unit that determines whether or not the voltage is below the value of , and outputs a battery voltage drop signal in the following cases; a cutoff control unit that issues a cutoff signal based on the battery voltage drop signal; and a transmission interface section for sending data to a telephone line.

Function The present invention uses the above-described configuration to detect and determine battery voltage drop, and sends battery voltage drop information to the telephone line, so that gas utilities can immediately detect a battery voltage drop in the gas cutoff device and perform gas cutoff. It is possible to know about equipment abnormalities and take prompt action for gas consumers.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG.

The battery voltage of the gas cutoff device is detected by a battery voltage detection unit 1, and a voltage determination unit 2 determines whether or not the battery voltage is below a predetermined value.If the battery voltage is below a predetermined value, a battery voltage drop signal is issued. It will be done. Then, the cutoff control unit 3 receives the battery voltage drop signal and outputs a cutoff signal to operate the cutoff valve. At the same time, the battery voltage drop signal is configured into a predetermined telegram by the transmission interface section 4, and is sent to the telephone line 5 as a telegram.

As described above, according to this embodiment, by providing a transmission interface unit that receives a battery voltage drop signal, composes it into a predetermined message, and sends it to the telephone line, the gas utility company can It is possible to immediately determine whether or not the battery voltage of the shutoff device is below a predetermined value, and to take prompt action to the gas consumer.Next, another embodiment of the present invention is shown in FIG. This will be explained with reference to. The difference in FIG. 2 from the previous embodiment is that a gas meter meter reading device 6 and a meter reading information sending section 7 are provided.

As described above, by providing the gas meter meter reading device 6 and the meter reading information sending unit 7, not only information on battery voltage drop but also gas meter reading information can be sent to the telephone line through one transmission interface unit 4. It can be sent to gas utilities. Since a single transmission interface unit can transmit battery voltage drop information and meter reading information, costs can be reduced.

Effects of the Invention As described above, the present invention includes a battery voltage detection unit that detects a battery voltage, a battery voltage detection unit that determines whether the battery voltage is below a predetermined value,
a voltage determination section that outputs a determination signal; a cutoff control section that outputs a cutoff output based on the determination signal output from the voltage determination section; and a cutoff control section that receives the determination signal output from the voltage determination section and determines a battery voltage determination signal. By providing an interface unit that configures the system into a message and sends it to the telephone line, the gas utility center can instantly know information about the voltage drop in the battery of the gas cutoff device, and can take prompt action to the gas consumer. This will help ensure even greater safety.
