摘　　要：智能变电站安全监控交互数据监测在检测的过程中存在数据信号接收较差,信息处理监测效率过低的问题,导致最终监测的结果较差。为此,基于Modbus通信协议提出了一种智能变电站安全监控交互数据监测方法。在构建数据通信网络拓扑的基础上矫正监控数据相位,分析信息化总线结构,优化数据监测方案,由此提升监测效果。根据分析的实验结果可知,该监测方法的监测频率图像较为稳定,当监测传输字节数量为60.12时,监测耗时相较于其余方法缩短约15 ms,表明该方法能够有效实现监控交互数据监测。In the process of intelligent substation safety monitoring interactive data monitoring,there are some problems,such as poor data signal reception and low efficiency of information processing,which lead to poor final monitoring results.Based on Modbus communication protocol,this paper proposes an interactive data monitoring method for safety monitoring of intelligent substations,corrects the monitoring data phase based on the construction of data communication network topology,and analyzes the structure of information bus,optimize the data monitoring program to improve the monitoring effect.According to the analysis of the experimental results,the monitoring frequency image of the monitoring method is relatively stable.When the number of monitoring transmission bytes is 60.12,the monitoring time is about 15ms shorter than other methods,it shows that this method can effectively realize monitoring interactive data monitoring.
