摘　　要：针对海洋传感器数据在水下、长距离传输困难的问题,提出了一种PLC长线传输电路系统。该系统采用电力线通信(PLC)技术,以CR600为控制核心,CR150为模拟前端配合芯片控制数据收发。通过脐带缆将数据回传到地面,再由地面控制系统与上位机对数据进行接收,实现海洋传感器数据的传输。为保证电路系统在水下1 000 m正常工作,设计了耐压仓,根据理论计算与COMSOL仿真,确定了耐压仓具体参数。经验证,该系统工作稳定,长时间传输数据接收完整,能够实现海洋传感器数据的长线传输。To solve the problem of underwater and long-distance transmission of ocean sensor data, a PLC long-line transmission circuit system is proposed. The system adopts power line communication(PLC) technology, CR600 as the control core, CR150 as the analog front end with chip control data receiving and sending. The data is transmitted back to the ground through the umbilical cord, and then the data is received by the ground control system and the upper computer, realize the ocean sensor data transmission. In order to ensure the normal operation of the circuit system in 1 000 m underwater, the pressure chamber is designed. According to the theoretical calculation and COMSOL simulation, the specific parameters of the pressure chamber are determined. It has been verified that the system works stably, the long-term data transmission is complete, and it can realize the long-term transmission of marine sensor data.
