摘要
阐述了选煤厂原煤输配系统采用PLC控制的主要特点,对输煤部分和配煤部分的电气控制系统进行硬件组态、软件设计,用压力继电器检测煤位高低以控制煤流大小,实现高精度配煤,系统中加入完善的连锁保护、报警和显示功能,突出了PLC在工业控制系统中的应用。
Transmission and distribution systems that use coal preparation plant control of the main features of PLC. Some of the coal handling and blending parts of the electrical control system hardware configuration and software design. Pressure testing relay to control the level of coal in coalsize. Achieving high - precision blending. Improve the system by adding the chain protection, alarm and display, highlighted the PLC in industrial control system applications.
