摘要
介绍了一种以Cortex-M3微处理器为核心、基于Modbus通信协议的温度测控系统。分析了系统功能,介绍了系统总体设计方案。给出了测控终端硬件电路设计,介绍了采用uCOS-Ⅱ实时操作系统实现的测控终端软件设计。利用Modbus通信协议,采用VC++6.0开发平台,结合Access数据库实现了监控主机的软件设计并给出了通信协议。实验结果表明:该系统能可靠实现数据的采集、传输和控制。
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. Experi- ments show that the system can implement the data acquirement, transmission and control reliably.
