摘要
介绍了黄陵矿业一号煤矿选煤厂集中控制系统的主要功能与要求,阐述了选煤厂集中控制的程序设计及控制类型,指出黄陵矿业一号煤矿选煤厂集中控制系统选用的Modicon Quantum 140系列PLC系统,主要包括物理控制网络按照信息层、控制层和设备层3层网络设计;控制程序应围绕生产工艺要求和集中控制的主要功能进行编制,尤其应注重设备故障检测、保护功能的实现;程启流程的连跳功能是选煤厂集中控制系统安全可靠运行的关键。
This paper introduced the main function and requirements of centralized control system of coal preparation plant in No. 1 coal mine of Huangling Mining Industry Co., Ltd., demonstrated the programming and control type of centralized control of coal preparation plant as well, it was also indicated that the PLC system in Modicon Quantum 140 series was chosen by this centralized control system, which mainly included physical control network which was designed according to 3 levels of network design （information level, control level, and equipment level） ; the control program should be wrote according to the production process requirements and main function of centralized control, especially the realizations of fault detect and protection should be paid attention; jumping continuously of starting the program was the key part for safe operation of centralized control system
