Intrinsically safe explosion-proof detector and intrinsically safe explosion-proof detection system

摘要

PROBLEM TO BE SOLVED: To provide an intrinsically safe explosion-proof detection system capable of suppressing the price per sensor, prolonging the battery life, and reducing the cost. An intrinsically safe explosion-proof detection system 100 outputs a detection unit for determining whether or not a predetermined abnormality has been detected and a determination result as a digital signal to a signal converter 72, and also outputs the signal converter 72 and a digital signal. A plurality of detectors 10 including an input / output unit for exchanging and receiving signals are provided. The intrinsically safe explosion-proof detection system 100 further includes a signal converter 72 that relays the transmission and reception of signals between the detector 10 and the host device 80, a power supply unit 74 that supplies power to the detector 10, and signal conversion. A cable unit 90 that includes a plurality of signal transmission lines provided so as to connect the device 72 and the input / output unit, and supplies power to the detector 10 from the power supply unit 74, and a host device 80. It includes a transmitter / receiver 76 that transmits / receives signals to / from the signal converter 72 by wireless communication. [Selection diagram] Fig. 2
