Design and Application of Measure and Control System Based on CAN-Bus for Large Pumping Station Auxiliary Equipments

摘要

This paper is focused on the measure and control system for large pumping station auxiliary equipments. The design of system has advantages as follows, functions of sensing measure, compensation calculation and policy control are decentralized to the intelligent measure and control equipments in the field improve stability and reliability of the system; digitalized application eliminates the analog signal transmission errors and fundamentally improves the accuracy of measure and control; CAN-Bus has a higher data transfer rate and distribution capacity of bus resources; isolated CAN-Bus design makes the system anti-overvoltage ability strong; simple requirements of communication network wiring highlight the economy of the system. The application of the system is also described in the paper.
