摘要
漯河中波台自安装238C防盗报警系统以来,多次出现误报现象,严重影响了发射及其他工作的正常进行。首先对该系统的工作原理进行了简单介绍,然后对误报故障现象进行了分析、处理,并改进了电路设计中存在的不足。改进后的运行数据表明,系统误报率明显下降,达到了预期的目的。最后,对本系统的设计提出了进一步完善的建议。
It has occured error alarm frequently since the 238C alarm systym against theft of Luohe MW radio rebroadeasting station had been installed, It has affected the normal operation of transmission and other relational facility. The article first introduces the work principle of the alarm system briefly. Then it analyzes and disposes the error alarm of the system, and overcomes the design of fault electronic circuit. It indicates that the error alarm rate has been reduced notablly since the system had.been improved. The improvement has attained our expectant. Finally we put forward more perfect designs to improve the system.
