为满足《煤矿安全监控系统通用技术要求》与《煤矿井下作业人员管理系统通用技术条件》中关于系统必须具有双机切换功能的要求,实现软件自监视与双主机自动切换的功能。采用VS2010开发平台、C#高级程序设计语言,结合多线程技术,设计一套双机软件切换系统,按照MT/T 772—1998中8.13规定的主要性能测试方法进行严格测试,该双机软件切换系统具备软件自监视功能,并能够满足通用技术要求的从主机到备用主机正常工作的时间小于5 min的要求,完成双机软件的自动切换,实现双机值守功能。
In order to meet the requirements of “general technical requirements of coal mine safety monitoring and control system” and “general technical conditions of coal mine workers’ management system”, the system must have the function of double-switchover function and realize the function of self-monitoring of software and automatic switchover of double-host. Using VS2010 development platform, C # high-level programming language, combined with multi-threading technology, design a set of dual-software switching system, according to the main performance test method of 8.13 of MT / T 772-1998 to conduct rigorous testing, the dual software switching system With software self-monitoring function, and to meet the requirements of the general technical requirements from the host to the standby host is less than 5 minutes of normal work time to complete the automatic switch between dual-software to achieve dual-duty function.
