Clock metering method of watt hour meter, device, computer equipment and storage medium

摘要

The present application relates to a power meter clock synchronization method, apparatus, computer equipment and storage medium. The method comprises: obtaining an absolute time and synchronizing an internal clock according to the absolute time; Transmitting a first time synchronization message to the watt hour meter at a first time by a preset communication protocol, and receiving a second time synchronization message fed back from the watt hour meter at the second time; Where the first time and the second time are the time of the internal clock; Obtaining a processing delay of a first time synchronization message according to the first time, the second time, and a transmission delay; Obtaining a correction time according to a processing delay, a transmission delay, a predetermined message assembly time, and a time of the internal clock; And synchronizing the local clock of the wattmeter by sending a time calibration message to the wattmeter, wherein the time calibration message includes a calibration time. The present invention uses an accurate clock source, and considers the transmission delay and processing delay of the message, so that the clock of the watt-hour meter can meet the demand in seconds.
