[0002] With the continuous deepening of the application of the power consumption information collection system, the promotion of time-of-use tariffs, the assessment and calculation of voltage line losses at various levels, and the reporting of power outages have put forward higher requirements for the time accuracy of power meters and collection equipment. The abnormal clock of smart power meters not only affects the success rate of power consumption information collection and the effective control of line loss rate, but also easily causes time-of-use rate measurement errors, leading to customer complaints.

[0003] As of 2021, there are more than 100 million 2009-version electric energy meters in operation in the State Grid system. A large number of clock anomalies often occur, which is an extremely unstable factor in the implementation of time-of-use electricity prices for residential customers. The alarm lights and white screens of 2009-version electric energy meters caused by clock anomalies have always been a hot topic for customers. Therefore, power supply companies must promptly and accurately analyze and handle the clock anomalies of smart electric energy meters.

[0004] The traditional methods for handling clock anomalies of the 2009 version of electric energy meters mainly include the following two methods:

[0005] 1) Batch replacement: For 2009 version electric energy meters with a large number of clock built-in chip failures, records should be kept and reported to the manufacturer in a timely manner. In order to ensure normal electricity consumption and accurate electricity charges for customers, batch replacement can be carried out first.

[0006] 2) Regular monitoring and manual maintenance: Establish a regular monitoring system for clock anomalies of the 2009 version of electricity meters, promptly discover clock anomalies of the 2009 version of electricity meters, and perform manual maintenance on the clock anomaly area, that is, press the programming button to make the electricity meter enter the programming mode for clock calibration, and press the programming button again after the calibration is completed to make the electricity meter close the programming mode.

[0041] In summary, the clock management device provided in this embodiment compares the clock of the clock component 5 to be managed with the standard time through the clock calibrator to obtain the time difference of the clock component 5 to be managed; when the time difference of the clock component 5 to be managed is greater than the threshold, the controller 4 controls the drive mechanism 2 to start, so that the transmission mechanism 3 moves under the action of the drive mechanism 2 to apply pressing force to the programming button 51 of the clock component 5 to be managed, so that the clock component 5 to be managed enters the programming mode or closes the programming mode, thereby realizing the automatic clock calibration function of the clock component 5 to be managed without human intervention. The clock management device realizes the electric pressing of the programming button 51 of the clock component 5 to be managed through the remote control driving mechanism 2, so that it enters the programming state, and then automatically sets the date and time, thereby solving the problem of inaccurate clock of the clock component 5 to be managed, especially the problem of out-of-tolerance clock of smart electric energy meter, which is not limited by the out-of-tolerance time and does not require on-site personnel participation. The smart electric energy meter clock is successfully managed to the system clock, effectively solving the problems of freezing and event time label errors caused by clock out-of-tolerance, electric energy metering errors of time-of-use rates, line loss abnormalities, etc. At the same time, the system automatically maintains, and once the electric energy meter clock is found to be out of tolerance, the clock can be managed in time to ensure the accuracy of user data collection.

[0051] Step S1, obtaining the address and clock of the clock device to be managed.

[0052] Step S2, obtaining the standard time of the address of the clock component to be managed according to the address of the clock component to be managed, and comparing and analyzing the standard time with the clock of the clock component to be managed to obtain the time difference of the clock component to be managed.

[0053] Step S3, when the time difference of the clock component to be managed is greater than the threshold, the controller controls the driving mechanism to rotate to press the programming button, so that the clock component to be managed enters the programming mode to realize automatic clock management of the clock component to be managed.

[0054] Step S4, after the clock management of the clock component to be managed is completed, the controller controls the driving mechanism to rotate to press the programming button again, so that the clock component to be managed turns off the programming mode. Specifically, after the clock management of the clock component to be managed is completed, the controller controls the driving mechanism to rotate to press the programming button again, so that the clock component to be managed turns off the programming mode and ends the clock management.

[0055] Since the clock management method and the clock management device have the same principle for clock management, the relevant parts can be referenced to each other and will not be described in detail in this embodiment.
