摘要
目前用电数据多数是高维多源异构数据,传统的监测终端在监测过程中存在较长的延迟时间,影响监测结果。为此设计基于大数据的用电安全智能监测终端。在原有的监测终端基础上,采用双CPU控制模式,设计数据采集模块,在原有信号采样电路添加电流互感器,同时对供电模块和传输通道采取相应的措施抑制脉冲干扰,获得监测数据后利用主成分分析法对高维多源异构数据降维处理,并根据用电安全标准,分析判断用电是否安全,完成监测。测试结果表明:与传统的监测终端相比,基于大数据的用电安全智能监测终端监测过程中延迟时间始终保持在30 ms以下,对监测结果影响较小,适合应用在用电安全监测中。
At present,most of the electricity data are high-dimensional multi-source heterogeneous data,and the traditional monitoring terminals have a long delay time in the monitoring process,which affects the monitoring results.For this purpose,an intelligent monitoring terminal for electricity safety based on big data is designed.On the basis of original monitoring terminal,double CPU control mode is adopted,data acquisition module is designed,and a current transformer is added in the original signal sampling circuit,as well as the corresponding measures is taken to restrain pulse interference for power supply module and transmission channel.After obtaining the monitoring data,principal component analysis(PCA) is used to reduce the high dimensional multi-source heterogeneous data dimension,and according to the electrical safety standard,monitoring and analyzing whether electricity is safe to complete the test.The test results show that:compared with the traditional monitoring terminal,the delay time of the intelligent monitoring terminal based on big data is always below 30 ms in the monitoring project,which has little impact on the monitoring results and is suitable for application in the monitoring of electricity safety.
