Method of transmission delay prediction for centralized meter reading system based on wideband carrier technology
摘要
Abstract
Wideband carrier communication technology is more and more widely applied in electricity information acquisi-tion system,and meter reading is a typical application of wideband carrier communication in state power grid. However,it is dif-ficult to evaluate the performance of wideband carrier communication products when using them due to the poor compatibility among current wideband carrier communication products and lack of the unified communication standard and protocol. The aver-age transmission delay of meter reading is an important index for evaluating wideband carrier meter reading,and low transmis-sion delay means stable network structure,fast reading response,and efficient data transmission,and can improve the data ac-quisition efficiency of electricity information system. To evaluate the performance of centralized meter reading products properly, a transmission delay prediction method for wideband carrier meter reading is proposed. According to the sampling time and net-work topology structure,the multiple linear regression method is adopted to predicate average transmission delay for meter read-ing. The experimental results verified the feasibility and effectiveness of the prediction method.关键词
