摘要
针对传统大型烘房温度控制不精确,自动化水平低的问题,设计了基于PID技术的大型烘房远程温度控制系统。系统通过中心PC机设置PID控制器参数和目标温度,并将所设置参数传输到每个监控点的下位机上;下位机对所监控区域的温度进行监控,并通过PID控制器进行调节,同时把所监控的温度信息上传给PC机。模拟实验的结果表明:系统工作可靠,控制精度高,具有较高的自动化控制能力。
In view of the temperature control of traditional large drying room not accurate and low automation level,the remote temperature control system of large drying room was designed based on PID technology; The PID controller parameters and target temperature of system was set up by center PC,and sent the parameters to each monitoring point of MCU; Temperature was monitored by MCU and adjusted by PID controller; At the same time the information of monitored temperature was sent to the PC. The simulation test of results show that the system is reliable,has a high control precision and high automatic control ability.
