摘　　要：电厂输煤皮带经常出现的超载现象是导致输煤作业事故发生的主要原因之一。从皮带输运流量分析、SQL查询语句优化等方面阐述了基于电子皮带秤历史数据库进行故障分析的方法,并在此基础上开发了电子皮带秤在线监测及故障分析软件。该软件实现了对输煤皮带流量的实时监测,同时为管理人员提供了灵活的基于皮带秤历史数据库的故障分析、流量追忆等功能。Overload, which occurs frequently in strap-transferral coal-burning system of power plants, is one of the main factors that result in coal-transferred accidents, The technique of malfunction analysis on coal-transferred system based on historical database of Electronic Strap Scales by analysis of strap-transferred flux and the optimization of SQL query sentences is expatiated. Based on the analysis, the software of Electronic Strap Scale Online Monitoring and Malfunction Analyzing System is developed. Its application realizes the flux online monitoring of coal-transferred system and provides the functions to analyze malfunction, retrospect coal-flux for the authorized managers.
