提出了一种基于串口通信服务器的新型分布式中频供电自动监测系统的设计方案,并详细地阐明了系统的实现原理方法及关键技术。该系统利用了串口服务器的实时控制转换功能,实现了双机备份冗余数据采集功能。新装置采用网络自诊断技术及光电隔离通讯接口,提高了通讯抗干扰能力,通讯采用报警信息数据优先发送及重复循环发送等技术,克服了原监测系统网络通信速度慢的弊端,增强了供电监测系统报警反映的快速性及可靠性。经现场实际运行表明,新供电监测系统比原系统功能更加完善,使用更加方便,具有更高的可靠性和稳定性,报警更加迅速,而且便于事故后故障分析等优点,同时还具有很强的系统扩展能力及推广价值。
Proposed a serial communication server based on the new distributed IF power supply automatic monitoring system design, and a detailed illustration of the system implementation principle and key technologies. The system takes advantage of the real-time control of the serial port server conversion function, to achieve a redundant dual-machine backup data acquisition capabilities. The new device uses network self-diagnostic technology and optoelectronic isolation communication interface to improve the communication anti-interference ability, the communication uses the alarm information data to send first and repeat transmission technology to overcome the shortcomings of the original monitoring system network communication slow, and enhance the power supply monitoring System alarm reflects the rapidity and reliability. The actual operation of the site shows that the new power monitoring system is more complete than the original system, more convenient to use, with higher reliability and stability, more rapid alarm, and easy fault analysis after the accident, etc., but also has a strong System expansion capacity and promotion value.
