It is.

FIG. 1 is a schematic explanatory diagram of a first transmission line fault monitoring system (first system) which is a specific example of the fault monitoring system according to the embodiment of the present invention. As shown in FIG. 1, the first system is installed in each of the towers (power transmission towers), detects a power transmission failure such as an insulation breakdown due to a lightning strike, and has a terminal device 1 as a terminal monitoring means for wirelessly transmitting failure information. ,
It comprises a public line network 4 and a center device 5 as central monitoring means provided in a monitoring center. In particular, the terminal device 1-n is provided in a public line network area as a public line connection means.

Each component of the first system will be specifically described. The terminal device 1 not only transmits the fault information associated with the fault detected by itself, but also receives and amplifies the fault information transmitted from the other terminal devices 1 as a feature of the first system, and stores the amplified fault information. It also has the function of a relay device such as transmitting to the terminal device 1 of an adjacent tower. The specific configuration of the terminal device 1 will be described later with reference to FIG.

According to the present invention, when the central monitoring means receives the fault information, the central monitoring means outputs an instruction to close the gas valve for switching gas supply / non-supply to the terminal monitoring means which has issued the fault information, and outputs the fault information. Terminal monitoring means other than the terminal monitoring means that has issued the fault information, transmits an instruction in the reverse direction to the failure information in a relay manner, and the terminal monitoring means that has issued the failure information performs the operation of closing the gas valve according to the received instruction. As a failure monitoring system, when a failure occurs, the gas valve can be closed by remote control, the damage due to the failure can be minimized, and the recovery work can be performed safely.

According to the present invention, similarly to the relay transmission of the fault information, the gas fault monitoring system periodically detects the gas usage and transmits it to the central monitoring means. There is an effect that convenience can be improved.
