And it is difficult to meet the clock for new business transactions synchronization accuracy requirements. Under the original metering clock system, a multi-source clock weighted fusion technology was proposed that used 5G communication modules as reference clocks, and used Kalman filtering to complete step-by-step clock correction at all levels of network nodes to achieve coordinated correction of different external reference clocks. The highest clock synchronization accuracy ensure the consistency of real-time data collection clock. Based on field test data collected by the Shenzhen Power Supply Bureau, the results showed that the electricity bill settlement after clock synchronization optimization processing is closer to field settlement.Read More
