基于单片机的自由活塞制冷机测控系统设计
资料介绍
为了实现对自由活塞斯特林制冷机相关参数的测控,开发了一套基于HCS12单片机的测控系统,该测控系统采用MC9S12DG256单片机,选取了合适的传感器测量压力、温度、电压和电流等参数;采用PC机作为上位机,使用组态王软件设计了人机对话窗口;为了保证制冷机安全可靠运行,采用反电动势控制策略实现制冷机直线电机行程控制,采用快速制冷与温度PID控制相结合的控制策略实现制冷机冷端温度的控制;其经验可以用于其它类似的测控系统的研制工作。
In order to realize the measurement and control of relevant parameters of free piston Stirling refrigerator,a measurement and control system based on HCS12 Embedded Microcontroller is developed.MC9S12DG256 Embedded Microcontroller is used in the measurement and control system,and suitable sensors are selected to measure the parameters of pressure,temperature,voltage and current.The PC machine is used as the host computer,and the human-machine conversation window is designed by using Kingview software.In order to ensure the safe and reliable operation of the refrigerator,the back EMF control strategy is used to realize the travel control of the linear motor of the refrigerator,and the fast refrigeration and temperature PID control strategy are used to realize the temperature control of the cold end of the refrigerator.Its experience can be applied to other similar measurement and control systems.
