In this context, this paper studies and develops an intelligent measurement and control system based on CAN fieldbus technology to detect and control parameters such as pulp concentration and multi-stage dryer temperature in the papermaking process to meet the requirements of the papermaking process. and paper quality control requirements ensure uniform paper quality.An intelligent measurement and control system is a typical application system for microcomputers (mainly a single-chip microcomputer), which is a combination of computer technology, modern measurement technology, communication technology and network technology. Regardless of in terms of measurement speed, measurement accuracy, sensitivity, degree of automation and economic performance, it is unmatched by traditional control systems. This became the direction of development of automatic control.
