Abstract: The acquisition success rate of the acquisition metering device is the key to ensure that the electricity consumption data is truly "available and usable". In order to analyze the influencing factors of the low-voltage acquisition success rate of power consumers, this paper divides the electricity consumption data transmission of power consumers into two aspects: uplink channel and downlink channel, analyzes and summarizes the influence of various factors on the communication channel, judges the factors that lead to abnormal acquisition of acquisition terminals and metering devices, and puts forward relevant measures to improve the acquisition success rate, providing strong support for metering device maintenance, power charge recovery, and line loss management.
