A relatively complete automatic control system/device should be installed in clean room, which is very beneficial to ensuring the normal production of the clean room and improving the operation and management level, but the construction investment needs to increase.
Various types of clean room have different requirements and technical parameters including monitoring of air cleanliness, temperature and humidity in clean room, pressure difference monitoring in clean room, monitoring of high-purity gas and pure water, monitoring of gas purity and pure water quality and the scale and area of clean room in various industries also vary greatly, so the functions of the automatic control system/device should be determined according to the specific conditions of the clean room project, and should be designed into various types of monitoring and control systems. Only clean room is designed with distributed computer control and monitoring systems.
The automatic control and monitoring system of modern high-tech clean room represented by microelectronic clean room is a comprehensive system integrating electrical technology, automated instrumentation, computer technology and network communication technology. Only by correctly and reasonably using each technology, the system can meet the required control and supervision requirements.
In order to ensure the strict requirements for production environment control in electronic clean room, the control systems of public power systems, purification air conditioning systems, etc. should first have high reliability.
Secondly, different control equipment and instruments are required to be open to meet the requirements for networked control of the entire clean room. The production technology of electronic products is developing rapidly. The design of the automatic control system of the electronic clean room should be flexible and scalable to meet the changes in the control requirements of the clean room. The distributed network structure has a good human-computer interaction interface, which can better realize the detection, monitoring and control of the production environment and various power public equipment, and can be applied to clean room control using computer technology. When the parameter index requirements of the clean room is not very strict, conventional instruments can also be used for control. However, no matter which method is used, the control accuracy should meet the production requirements, achieve stable and reliable operation, and achieve energy saving and emission reduction.
