Research on Visualized Monitoring Model of Low Voltage User Power in Station Distribution

由于现有配用电低压用户电能可视化监控模型的数据采集设备频繁上报电能数据,出现电能数据产生部分丢失问题,导致监控模型误码率较大。为此,设计基于LoRa无线技术的低压用户电能可视化监控模型。设计LoRa采集设备,平衡PCB板结构,构建LoRa网关电路结构。以信号的插补参数作为电能集抄方案的优化参数,限制采集设备的上报频率,设定物理网的监控点后,获取监控任务的优先级,实现监控功能。利用两种传统监控模型与所设计监控模型进行对比测试,结果表明设计模型得到的误码率明显降低。

Due to the frequent reporting of power data by the data acquisition equipment of the existing visual monitoring model of low-voltage power users with power distribution,the problem of partial loss of power data appears,which leads to a large bit error rate of the monitoring model.Therefore,a visual monitoring model of low-voltage user power based on LORA wireless technology is designed.It designs LORA acquisition equipment and balance PCB structure,builds the LORA gateway circuit structure.The signal interpolation parameter is taken as the optimization parameter of the electric energy gathering scheme,and the reporting frequency of the acquisition equipment is limited.After the monitoring points of the physical network are set,the priority of the monitoring task is obtained,and the monitoring function is realized.After preparing the experimental equipment with known parameters and building the test platform,the two traditional monitoring models and the designed monitoring model were compared and tested.The results show that the designed model can significantly reduce the bit error rate.
