Application of PICs and microcontrollers in the measurement and control of parameters in industry

摘要

This paper describes the use of microcontrollers in low-cost control applications. The main feature of the system is the use of programmable integrated circuits (PICs) to perform direct control processes within a plant. In this work, a control model based on distributed functions in levels is proposed to increase control task efficiency. With reference to a previous model, an efficient and simple control system is suggested for industrial applications. The designed system distributes its supervisory and control tasks in different units using commercial microcontroller devices. The results obtained with the previous system are described, which let us check the reliability and flexibility of the proposed model. Finally, several operational alternatives for the developed system are suggested.
