摘要
在电力监控系统中,既要对电力数据进行高精度的实时采样,又需要和上位机进行标准通信。利用DSP强大的数据处理与通信能力,对基于以太网IEC60870-5-103规约的通信系统进行了研究与开发,完成了软硬件系统的设计。利用DSP完成采样、滤波和用户I/O控制。在以太网链路上,采用TCP报文与UDP报文相结合的方式完成裁剪后的103通信,在实际应用中取得了良好的效果。
Power control system needs high-level sampling to the power analog value as well as communication with the UP-Level machine. We made use of the strong performance in data operation and communication of DSP to have carried out the research and development on the Ethernet-based IEC60870-5-103 electric protocol communication system, and have completed the hardware and software system design. Besides, the functions of sampling, filter wave, and User I/O control were accomplished with DSP. By implementing clipped 103 communication protocol on Ethemet links with combined TCP and UDP packets, it has obtained the great effects in practical applications.
