| Abstract: | Clean room technology in China was originated in the 60s of last century.At the time,clean room technology for the quality requirements of military,precision instruments,aircraft instrumentation and electronics industry,was borned as an emerging technology,to meet the needs of these industries processing and experimental study of precision,miniaturization,purity,quality and reliability.The system uses PID control principle,adopts Siemens PLC S7-300,on the base of STEP7 and WINCC＇ s cascade PID to control air cabinet,to achieve the precise temperature and humidity on the charged area。The system control program has been applied to a laboratory clean room control air cabinet,The results show that the system control program is easy to control,good effect,Fast response;High stability;and high precision。 Besides,the performance indicators are in line with requirements. |
