摘要: 针对深部开采矿井存在的机电硐室的高温热害问题,设计了一套机电硐室用低风速、低湿度、可实现冷量自动调节的降温系统,详细介绍了系统的硬件设计和上位机软件设计,同时重点介绍了PLC内嵌的带死区增量型数字PID算法。实际应用结果表明,该系统可有效降低机电硐室内的温度,实现了冷量的自动控制、地面监控、报警预警等功能。Abstract: In view of problem of high temperature thermal damage of electromechanical chamber of deep mining mines, the paper designed a set of cooling system for electromechanical chamber with low wind speed and humidity, which can realize automatic adjustment of cooling capacity. It introduced hardware design and PC software design of the system, and described dead zone incremental digital PID algorithm embedded in PLC in details. The application results show that the system can effectively reduce indoor temperature of electromechanical chamber, and achieves functions of automatic control of cooling capacity, ground monitoring, alarming and warning.
