资料介绍

在缆道测流的动力调速系统中,由于交流变频电路产生的噪音,对高频无线电接收发射系统影响很大,使操控人员很难辨别接收到的流速信号。为解决此问题研制了一套直流信号接收系统,介绍了系统的各部件安装方法、信号接收原理以及调试过程。经过多次水下实验、安装调试,排除了各种干扰故障,有效解决了由变频电路产生的高次谐波对信号系统高频发射接收电路产生的严重干扰,整个系统具有便于操作和维修的优点。

In the application of dynamic velocity adjustment system,the noise caused by AC frequency conversion circuit affect the high frequency radio receiving and emission system for flow velocity signal,making it difficult for operators to identify the flow velocity signal.We developed a DC signal receiving system.The components installation,signal receiving principle and debugging process of the proposed system are described.After the repeated underwater tests,all kinds of interferences and faults are eliminated by installation and debugging.The influence of higher harmonics induced by AC frequency conversion circuit on the high frequency radio receiving circuit can be avoided as well,and the operation and maintenance are convenient.
