CNIC-01903 SUEC国0001 中频供电微机自动监测系统的研究与实现 王运通徐斌 (中核陕西铀浓缩公司，陕西汉中，723014) 摘要 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o 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。 关键词:中频供电分布式系统供电自动监测系统串口通信服务器以太网 174 Study on Intermediate Frequency Power Supply Automatic Monitor System ( In Chinese) WANG Yuntong XU Bin (Shaanxi Uranium Enrichment Co. ,ltd. CNNC ,Shaanxi Hanzhong ,723014) ABSTRACT A new design project of the automatic monitor system for the intermediate frequency power supply system by using the communication server is put for- ward and the realizing principle method and the key technique are clarified in detai l. This system made use of the conversion function with the series commu- nication server s control , realized the data collecting function by the double ma- chine backup and redundancy. The new network system adopted the photoelec- tric-insulated-communication connect device and the diagnosis technique , in- creased the anti-interference ability , the communication adopted the technique by the alarm inforrrlation sending out in first and circularly repeating , the slow- ly speed is overcame in the original monitor network system , and strengthened the celerity of the monitor system and 出e reliability of the alarm report. After the new monitor system running , the result shows that the functions is more perfect than the origi
