摘要
针对电厂自动化应用的嵌入式数据采集监测系统需求,在嵌入式Linux环境下设计开发了基于Mod- bus协议的ARM嵌入式监测平台,实现了ASCⅡ和RTU 2种通信模式的串口Modbus协议主站,以满足与各串口Modbus协议从站设备的通信。嵌入式监测平台除了主要完成数据采集、数据处理等功能,还提供了数据采集接口、多种网络通信接口和人机交互接口等功能。通过对该平台的严格测试,所提供的串口Mod- bus协议主站服务程序运行稳定、可靠。
An ARM embedded monitoring platform with embedded Linux operation system is developed based on Modbus protocol for the embedded data acquisition monitoring system applied in power plant automation. Its Modbus master station implements both ASCII and RTU communication modes for communicating with Modbus slave devices. It supports mainly the functions of data acquisition and processing, as well as different interfaces for data acquisition, network communication and operation. Test resuhs show that, the service routines of Modbus master station run stably and reliably.
