According to one embodiment, a thermocouple abnormality detection system including: a plurality of thermocouples each including a plurality of thermocouple wires housed in a sheath; a transmission signal conversion unit configured to convert a thermo-electromotive force generated by each of the plurality of the thermocouple wires to a transmission signal and to output the transmission signal; a transmission unit configured to transmit the transmission signal outputted from the transmission signal conversion unit; and an abnormality detection circuit configured to detect an abnormality of each of the plurality of the thermocouples by comparing, with each other, the transmission signals obtained from the plurality of thermocouple wires provided in each of the thermocouples.

Thermocouple abnormality detection system and detection method thereof

A signal transmission and reception system includes a transmitter adapted to transmit a signal by radio, and a receiver adapted to wirelessly receive the signal from the transmitter and transmit the signal to a monitoring and control device of a plant through a transmission cable connecting the receiver to the monitoring and control device, wherein the transmitter and the receiver are provided in the plant, and wherein the receiver is attached to a cable tray used to lay a cable other than the transmission cable.
