摘　　要：设计并实现了基于海洋投弃式声速仪(XSV)的通信系统。以2DPSK信号为传输信号,以单根双股漆包线为通信信道,设计了解调部分的高压偏置电路、放大滤波电路以及软件解调算法。与传统通信系统相比,该系统并未采用以FPGA或其他解调芯片为基础的解调电路,而是充分利用核心处理器STM32F407主频高的优势,在片内完成数据解调及数据上传功能,从而简化了电路,为测量提供了便利。通过试验,对解调数据进行了分析。测试结果表明,该通信系统的设计具有可行性、可靠性,满足复杂海洋环境下对于通信质量的要求。A communication system based on the ocean expendable sound velocity(XSV) was designed and implemented. The 2DPSK signal was used as the transmission signal, and the single double-stranded enameled wire was used as the communication channel. The high voltage bias circuit, amplification filter circuit and software demodulation algorithm of the demodulation circuit are designed. Compared with the traditional communication system, the system does not use the demodulation circuit based on FPGA or other demodulation chip, but fully utilizes the advantage of the core processor STM32F407 to achieve high frequency, complete data demodulation and data upload on the chip. The function simplifies the circuit and facilitates measurement. The demodulated data was analyzed through experiments. The test results show that the design of the communication system is feasible and reliable, and meets the requirements for communication quality in complex marine environments.
