Measurement and Control System Based on Cortex-M3 and Modbus Protocol

Haiping Liu

Abstract

A temperature measurement and control system based on Modbus protocol using Cortex-M3 microprocessor as kernel was introduced.The system functions were analyzed and the overall design scheme was introduced.The terminal hardware circuit design and software design which adopted uCOS-Ⅱ real time OS were provided.Using Modbus protocol,VC++ 6.0 development platform and Access database,it realized the monitoring host software design and provided communication protocol.Experiments show that the system can implement the data acquirement,transmission and control reliably.
