In recent years, with the rapid development of technologies such as information, internet, and internet of things, the intelligentization, networking and security of industrial control systems have become the focus of attention of governments and enterprises in various countries. Industrial automation instrumentation is the core of industrial control systems. The key components. For a long time, the high-end products in this field have been controlled by foreign monopoly enterprises, holding the development level and security capabilities of China's industrial control system.

Under the support of the National 863 Program, Shanghai Automation Instrumentation Co., Ltd. and Zhejiang University cooperated to develop independent controllable on-chip control systems (Control Module on Chip, abbreviated: CMC) and software development technologies conforming to IEC61131-3. Based on the four major categories of industrial automation instrumentation such as temperature, pressure, liquid level, and electric actuators, the CMC-based intelligent instrumentation software and hardware development platform was built, and the low-power explosion-proof technology based on the CMC-based smart instrumentation was solved. Advanced fault diagnosis technology, anti-electromagnetic interference technology, and industrial network communication technologies such as EPA and MODBUS improve the circuit integration of domestic smart instrumentation, the reliability and applicability of the product, and improve the product's performance and functionality.

The development and application of intelligent instrumentation for CMC's own core software and hardware realized the localization of the core technology of smart instrumentation, and improved the autonomous controllability and level of domestic instrumentation. At present, the four major types of industrial automation instrumentation products such as intelligent temperature, pressure, liquid level transmitters, and intelligent electric actuators developed by the research group have already achieved large-scale engineering applications in the process industry, and they have appeared in thermal power, Petrochemical, chemical and environmental protection industries have a wide range of applications.
