为了实现封堵器海洋工作环境中的无线遥控动作,封堵器在海底工作中采用了水声通信技术。文章首先介绍了水声通信系统的整体设计。在前期工作中,从影响水声通信的因素出发,对水声通讯频率的选择及水声换能器的选型进行了研究,确定了水声通讯的载波频率。在此基础上提出了基于单片机的水声Modem的制作方案,设计了单片机系统电路。并对单片机至Modem的电路进行了初步调试,实现了单片机到Modem的初始化连接。完成了信号接收滤波放大电路线路的设计和制作。
In order to realize the wireless remote control action of the occluder marine working environment, the occluder adopts the underwater acoustic communication technology in the seafloor work. The article first introduced the overall design of underwater acoustic communication system. In the previous work, starting from the factors that affect the underwater acoustic communication, the frequency of underwater acoustic communication and the selection of underwater acoustic transducers were studied, and the carrier frequency of underwater acoustic communication was determined. On the basis of this, a fabrication scheme of underwater acoustic Modem based on singlechip is proposed and a singlechip system circuit is designed. And carries on the preliminary debugging to the circuit of the one-chip computer to Modem, has realized the initial connection of the one-chip computer to Modem. Completed the signal receiving filter amplifier circuit design and production.
