Deck unit circuit of AC (Alternating Current) 500v power line carrier shipborne remote communication system

Abstract

The invention relates to a deck unit circuit of an AC (Alternating Current) 500v power line carrier shipborne remote communication system. The deck unit circuit comprises a power circuit, an AC 500V controlled circuit, a power line carrier module receiving circuit, a level switching circuit and a master control circuit, wherein the power circuit is used for supplying power to the other circuits; the AC 500V controlled circuit is used for receiving an AC 500V switch command of the master control circuit so as to determine the on-off of AC 500V of the AC 500V controlled circuit; the power line carrier module receiving circuit is connected with the AC 500V end of the AC500V controlled circuit, demodulating received information and transmitting the demodulated information to the master control circuit; the level switching circuit is used for receiving sensor data of the master control circuit and then uploading the data to an upper computer. According to the deck unit circuit disclosed by the invention, an adopted autonomously improved power line carrier module and a power line carrier module of a submerged system can be subjected to data transmission on a AC 500V power line, so that the sensor data of the submerged system can be acquired.
