摘要
针对目前显微镜载物台温控系统的超调量大、控制温度不恒定等明显缺陷,文中设计了一种基于STC12C5608AD单片机的显微镜载物台自动温控系统。采用高精度的NTC10KB3950K薄膜热敏电阻作为温度传感器,运用模糊自整定PID算法,温度控制范围为0~50.0℃,温度控制精度为±0.1℃。该温控系统具有操作简单、响应速度快、超调量小、稳定可靠等优点,具有良好的实用性。
As the present microscope stage's automatic temperature control system has its deficiencies of large/big/high overshoot and inconstant temperature controlling,an automatic temperature control system for microscope stage is invented,which is based on STC12 C5608 AD microcontroller.The system uses the high-precision NTC10 KB3950 K film thermal resistor as the temperature sensor.And Fuzzy-PID algorithm is applied.What 's more,the control temperature ranges from 0 ~ 50.0 ℃.Temperature control precision is less than ± 0.1℃.The application result shows that this new system has the advantage of simple operation,fast response,less overshoot,stability and reliability,which means it has certain practicability.
