调度台录音系统声控变压控的处理

Processing of voice control converted to pressure control in the dispatch station recording system

调度录音系统是电力系统事故调查取证的重要依据之一,因此,调度录音系统的工作质量直接关系到对电力调度系统安全维护的成败。文章针对黄冈电力调度台声控录音系统因受调度员讲话时的随意性控制,出现了将一次性通话记录硬分割成数段文件存储,易造成遗漏字句,使录音走样的现象,提出用压控取代声控启动录音的整改方案。其中,压控电路设计是这项整改的技术关键,文章着重对此进行了描述,并对实施步骤进行了介绍。

The dispatch recording is one of important proof for the electrical power system accident investigation evidence collection. Therefore dispatcher＇s every order even every character all is directly linked with the electrical network security. Based on dispatcher speaking random, the paper puts forward a reform scheme using pressure control instead of voice control. And the pressure circuit design is the key technology in this scheme. This paper describes it and introduces the implement process.
