摘要
分析了嵌入式系统的发展及其网络通信技术的研究现状和缺陷,针对嵌入式系统硬件资源有限和工业控制中实时性要求高的特点,以Rabbit2000为开发平台,设计并实现了监控工作站和控制器之间基于Modbus/TCP协议的通信,给出了系统的具体配置和使用非阻塞型函数编程的主要流程以及详细说明;实际应用表明,采用Modbus/TCP协议进行通信的楼宇控制器满足实时性要求,有广阔的推广价值。
The development, research situation and deficieneiey of network communication in embedded system are analyzed. Consider ing the features, i. e. , the limit of hardware resource in embedded chip and strict requirement to real time, the network communication using Modbus/TCP in embedded system is realized based on Rabbit2000. The configuration and flow chart according to function without bloc king are provided in detail, The protocol has been embedded in a certain building controller. The practice shows that the building controller based on Modbus/TCP satisfies the real-time requirement. It is worthy of popularization.
