Description

Calibration method and device for electric energy meter clock

Technical field

The present invention relates to the field of electric energy meter calibration, and specifically to a calibration method and device for an electric energy meter clock.

Background technique

In related technologies, with the continuous application of electricity consumption information collection systems, the promotion of time-of-use tariffs, assessment and calculation of voltage line losses at various levels, and reporting of power outage events, the accuracy of the energy meter clock has been raised. Higher requirements. Abnormal energy meter clocks not only affect the success rate of electricity consumption information collection and effective control of line loss rates, but can also easily cause time-of-use rate measurement errors and trigger customer complaints. Abnormal clocks will cause the alarm light of the energy meter to flash and a white screen to appear, which will have an impact on residents' implementation of time-of-use electricity prices.

At present, there are five main ways to deal with clock abnormalities in electric energy meters. The following takes the 2009 version of the electric energy meter as an example: 1) Remote time correction: For the 2009 version of the electric energy meter whose clock deviation is within ±5min, use the broadcast time correction command on the host computer. The station can perform remote time synchronization operations. 2) Encryption modification: For the 2009 version of the electric energy meter with a clock deviation of more than 5 minutes, the relevant personnel should go to the site to operate the electric energy meter and use an ordinary handheld computer or a special program for laptops to adjust the time. When adjusting the time, the programming key must be manually opened, and the permissions and passwords must be correct. . 3) Strengthen management and control: For electric energy meters with damaged built-in components and depleted clock batteries of the 2009 version, the damaged components or batteries can be replaced on site to avoid clock abnormalities again. At the same time, we will strengthen the management and control of transportation and installation processes to avoid component damage to smart energy meters during transportation and installation. 4) Batch replacement: For 2009 electric energy meters with built-in clock chip failures in large quantities, records must be kept and reported to the manufacturer in a timely manner. In order to ensure customers' normal electricity consumption and accurate electricity bills, batch replacement can be carried out in advance. 5) Regular monitoring: Establish a regular monitoring system for clock anomalies of the 2009 version of the electric energy meter, timely discover the abnormality of the clock of the 2009 version of the electric energy meter, strengthen the analysis and processing of the problems, and improve the healthy operation level of the 2009 version of the electric energy meter.

Traditional solutions can only remotely solve the situation where the clock of the 2009 version of the electric energy meter is out of tolerance within 5 minutes. When the clock of the 2009 version of the electric energy meter is out of tolerance by more than 5 minutes, personnel can only go to the site and operate the 2009 version of the electric meter programming button on the meter to set the clock. Calibration or direct replacement of energy meters is not only extremely costly to maintain, but also inefficient.

No effective solution has yet been proposed for the above-mentioned problems existing in related technologies.

According to an embodiment of the present invention, a calibration method for an electric energy meter clock is provided.

Figure 1 is a flow chart of a method for calibrating an energy meter clock according to an embodiment of the present invention. As shown in Figure 1, the invention includes the following steps:

Step S101: Obtain the clock information of the target electric energy meter.

As mentioned above, abnormal energy meter clocks have caused instability in residents' implementation of time-of-use electricity prices. Therefore, power supply companies must make timely and accurate fault analysis, judgment and processing of abnormal energy meter clocks. The electric energy meter in the embodiment of this application is specifically described by taking the traditional 2009 version electric energy meter as an example.

As mentioned above, the calibration system is initialized and the clock information of the target electric energy meter is obtained.

Step S102: After receiving the broadcast time adjustment command, calculate the time difference between the system time included in the broadcast time adjustment command and the clock information of the electric energy meter.

As mentioned above, this application provides a technical solution for remotely calibrating the clock information of an electric energy meter through a broadcast time correction command. Specifically, the time difference between the system time and the electric energy meter clock is calculated based on the broadcast time correction command. Among them, the broadcast time adjustment command includes the system time.

It should be noted that the clock information of the electric energy meter at least includes clock time and date and time.

Step S103, determine whether the time difference is greater than or equal to a preset threshold.

As mentioned above, in the embodiment provided by this application, preferably, the preset threshold is 5 minutes, and the preset threshold can be specifically set according to different scenarios.

Step S104: When the time difference is greater than or equal to the preset threshold, the target electric energy meter is controlled to enter the programming state, and the date information and clock information of the target electric energy meter are calibrated in the programming state.

Specifically, this application provides an electric energy meter provided with a clock management module, in which a motor and a rotating pressure rod are provided on the clock management module. The motor drives the rotating pressure rod to move. When calibrating the clock information of the electric energy meter, the motor drives the Turn the pressure lever to press the programming button of the electric energy meter to make the electric energy meter enter the programming state.

As mentioned above, when the time difference is greater than or equal to the preset threshold, the programming button of the electric energy meter is operated by controlling the motor of the clock management module, so that the electric energy meter enters the programming state, and the date and time are automatically set in the programming state. Calibration operation.

Through the above method, this application can effectively solve the problem of abnormal clock of the electric energy meter. Even if the time difference is greater than the preset threshold, it can be processed one by one without the need for personnel to go to the meter site, which greatly saves manpower and material resources. Through the above This method effectively solves problems such as freezing and event time tag errors caused by clock outliers, energy meter measurement errors in time-of-use rates, abnormal line losses, etc. At the same time, the system automatically maintains. Once the energy meter clock is found to be out of tolerance, it can promptly Carry out clock management to ensure the accuracy of user data collection.

In an optional example, obtaining the clock information of the target electric energy meter includes: sending a read command to read the communication address of the target electric energy meter according to a preset protocol; reading the communication address of the target electric energy meter according to the read command; According to the communication address, the read data identification is sent; according to the data identification, the clock information corresponding to the target electric energy meter is read.

The default password is 000000, the permission is 02, which can be set externally, and the operator code is 12345678 by default.

First, set the date and week of the electric energy meter. According to the data identification 04 00 01 01 date and week in the DL/T645-2007 protocol, the unit is year, month, day and week. The day of the week needs to be calculated based on the date of the broadcast time adjustment command, and the written date and time are sent. Give the day of the week command to the electric energy meter, calibrate the date to the master station date, and then set the time of the electric energy meter. According to the data identification 04 00 01 02 time in the DL/T645-2007 protocol, the unit is hours, minutes and seconds, and extract the hours, minutes and seconds in the broadcast time adjustment command. Send a write time command to the electric energy meter to calibrate the time to the master station system time. After the above process is completed, the electric energy meter clock is calibrated to the master station system clock.

As mentioned above, after the electric energy meter clock is calibrated, the date and time of the electric energy meter are reacquired, and the stored electric energy meter clock is synchronized. Only when the broadcast time correction command is received again can the system clock and electric energy meter be accurately calculated. The clock is out of tolerance, so it is processed.
