摘要
小浪底水库无线遥控悬移质采样器的电流场通信系统主要由水面操作装置、水下控制装置、信号接收和发射天线(电极)以及电源模块等组成。采样器携带4个采样作业仓,水面操作装置采用4位二进制代码对操作按键编码,实现对作业仓的控制。对系统信息的编码方式、发射和接收电路组成结构、软件结构等进行了分析。实际应用表明,在小浪底库区坝前90 m水深处,铅鱼携带采样器深入库底淤泥层中通信依然可靠。
The current field communication system used in suspended sediment sampler of the Xiaolangdi Reservoir mainly comprises operating unit above the water,control device in water,signal receiving and transmitting antenna（electrode）,the power module and other components.The 4-bit binary code system is used to code the operating key in operating unit above the water which controls the four underwater container operations.The information encoding,transmitting and receiving circuit structure,software structure were analyzed in the paper respectively.The communication system reliability verifies in applications which use lead fish taking sampler to work in the reservoir bottom silt layer underwater 90 m depth in front of the reservoir dam.
