中波台自动化播出、监控系统电源的设计与实现

Design and Implementation of Power for the MW Automatic Broadcast and Monitoring System

中波台自动化播出、监控系统主要由信号源、自动控制播出、监听监看报警和安防等组成。其中,自动控制播出和监听监看报警各由一台工业计算机及相关设备组成,是自动化播出监控系统的关键设备。由于计算机对电网异常承受能力较差,特别是在出现电网突然断电、尖波、过压等故障时,很可能造成计算机硬件损坏、相关软件系统瘫痪、数据丢失等,会严重影响自动化播出监控系统的正常运转。所以,有必要对原有市电电源系统进行重新设计安装。

The medium ware automatic broadcast and monitoring system is mainly composed of signal source, automatic control broadcast, monitoring and alarm as well as security part. The automatic broadcast and monitoring system consists of an industrial computer and related equipment and so does the monitoring and alarm system. They play key roles in the whole automatic broadcast monitoring system. Since computers have a poor bearing capacity against abnormal grids, especially when there is sudden power failure, sharp wave or overvoltage, it may result in computer hardware damage, related software system paralysis and data lost, terribly affecting the normal operation of the system. Therefore, it is necessary to redesign and reinstall the original power supply system.
