针对煤矿电厂输煤系统逻辑程序复杂、容错性差、控制流程不尽合理等问题,研究提出了燃料输送系统工作流程的优化手段,同时对带式输送机常见故障提出了更为可靠的监测和诊断方法。详细介绍了该系统的硬件设计、软件设计和通信协议设置,对原有的输煤控制系统从控制策略和系统结构上进行了升级改进,实现了燃料输送系统的自动化控制及各级设备的故障保护。
Aiming at the problems of complicated logic program, poor fault tolerance and unreasonable control flow in the coal conveying system of coal mine power plant, the optimization method of working flow of fuel delivery system is put forward. At the same time, more reliable monitoring and diagnosis are proposed for the common faults of belt conveyor method. The system hardware design, software design and communication protocol settings are introduced in detail. The original coal control system is upgraded and improved from the control strategy and system structure to realize the automatic control of fuel delivery system and the failure of all levels of equipment protection.
