摘　　要：针对某些驼峰站场监测系统采集信息有限、监测质量较低的现状 ,文章介绍了一种以C10 4P多串口卡为核心的多串口通信方法以及其结构和软件设计 ,并阐述了一种提高通信数据可靠性的串口冗余方案。试验结果证明 ,系统实现了驼峰监测系统中多个控制设备的数据通信 ,提高了系统的监测质量 。Based on present situation of hump-supervision system that data acquisition is limited and supervision system has a low quality in hump yards,this paper introduces a multiport serial communication method with a use of C104P multiport serial board as its center,as well as its construction and design of software.Also,it describes a serial-redundancy program to promote the reliability of communication data.The experiment results indicate that the hump-supervision system implements data communication among multiple control with high quality and security in supervision.
