[0002] The annual calibration tasks of automated electricity meter calibration lines often reach hundreds of thousands or even millions of units, resulting in a huge workload. To ensure the accuracy of the output signals and calibration meter status of the calibration line, the line can be checked through periodic verification. That is, between two consecutive calibrations of ordinary electricity meters, the line is checked using appropriate verification standards and methods to determine whether it maintains the various calibration performance indicators at the time of the last verification. This ensures that the line works normally in daily calibration work and guarantees the accuracy and reliability of value transmission.

[0003] Due to their size, weight, and special assembly characteristics, assembly lines are difficult to move or transport. When manually inspecting them, staff need to carry verification equipment to check the verification positions of the assembly line, which is labor-intensive, time-consuming, and inefficient.

[0045] Example 1

[0046] Reference Figures 1-2 As one embodiment of the present invention, a verification method for an automated production line of electricity meters in full-test mode is provided, including:

[0047] S201: When the verification terminal receives a full-test mode verification task, it controls the verification of the electricity meter to connect at least one verification unit in the automated verification pipeline specified by the full-test mode verification task. It should be noted that:

[0048] The management terminal connects to the verification terminal and the automated verification line of electricity meters via wireless or wired networks. The management terminal sets the task mode for the verification task and sends the set verification task to the verification terminal and the automated verification line of electricity meters. For example, if the task mode is a full inspection mode verification task, the management terminal can be the production scheduling platform MDS system of the metering center.

[0049] When the verification terminal receives the verification task, it confirms that the task mode is a full inspection mode verification task. According to the requirements of the full inspection mode verification task, it controls the robot to install the corresponding number of verification energy meters on the pallet and enter the pallet conveyor line.

[0050] Specifically, the automated verification line for electricity meters has a controller that interacts with other devices at the management end. The controller can be installed in the line itself or be an external control device connected to the automated verification line for electricity meters. The control device can be a computer terminal.

[0051] Specifically, the management terminal sends the information of the full-inspection mode verification task to the controller of the automated energy meter verification line. The information includes the identifier of the full-inspection mode verification task and the test items. The identifier of the verification task includes the name and number of the full-inspection mode verification task. The management terminal can add a text description of the task mode of the verification task to the name of the verification task, such as "Period Verification - Full-inspection Mode". Based on the received identifier of the verification task, the automated energy meter verification line can identify that the verification task is a full-inspection mode verification task, and automatically transport the verification energy meters to the designated position of the empty verification unit according to the requirements of the full-inspection mode verification task. The number of verification energy meters can fill each verification unit.

[0052] It should be noted that the automated verification line for electricity meters includes multiple verification units, each corresponding to a verification task. When executing a verification task, the entire verification unit performs the same verification task. The verification task is the task executed by the automated verification line for verifying the performance of electricity meters. The verification electricity meter is equipped with a task identifier corresponding to the full-test mode verification task. The verification terminal can confirm whether the verification task being performed by the verification electricity meter is a full-test mode verification task by scanning the task identifier.

[0053] It should be noted that the electricity meter being checked is specifically a standard installed electricity meter, which can be a single-phase standard installed electricity meter or a three-phase standard installed electricity meter.

[0054] S202: Experimental project for verifying the full-test mode of the automated verification line control unit for electricity meters. It should be noted that:

[0055] The automated verification line for electricity meters can start the verification unit through the control terminal to perform the test items corresponding to the full-inspection mode verification task, or it can start the verification unit to perform the test items corresponding to the full-inspection mode verification task after receiving the instruction from the verification terminal.

[0056] It should be noted that the experimental items for the full inspection mode verification task include the basic error and the standard deviation estimate. The basic error refers to the electrical energy error of the device under test, including the working error of the standard meter and each meter position in the automatic verification line of the electricity meter. Specifically, it is the measurement error of electrical energy under reference conditions, which is determined by experiments and expressed as a relative error. The test points for the basic error test items can refer to the provisions of the current verification procedure for electricity meter verification devices.

[0057] It should be noted that the standard deviation estimate is an estimate of the standard deviation obtained from a finite number of measurements. It is a quantity that characterizes the dispersion of the measured values. In this invention, it refers to the standard deviation of the basic error of the automatic verification line of the electricity meter detected in full-test mode. It is used for the analysis of power stability and stability deviation data. Specifically, it means that under reference conditions, the relative error is measured at different load points in a prescribed manner, and then the standard deviation estimate is calculated according to the prescribed formula. For the specific prescribed method and the prescribed formula, please refer to the provisions of the currently implemented procedure.

[0058] Specifically, if it meets the verification requirements of JJG597-2005, the error interval is greater than or equal to 10s, the original value error for each current point is 5, and the original value error for the estimated standard deviation of the rated current point test and power stability is 10.

[0059] S203: After the full-inspection mode verification task is completed, the verification terminal acquires the verification data of each verification unit in the verification unit, as well as the verification data from the verified energy meter, and analyzes the verification performance of the automated energy meter verification line based on the verification data and the verification data. It should be noted that:

[0060] The verification terminal has a built-in DLL dynamic database, which reads the calibration data and verification data from the management terminal. By comparing the calibration data and verification data, the calibration performance of each calibration unit can be analyzed. Specifically, the calibration data and verification data can be compared. If the comparison results are consistent, it means that the calibration performance of the calibration unit is normal. If the comparison results are inconsistent, the verification data is usually taken as the standard, which can determine that the calibration performance of the calibration unit is abnormal. It can also be further confirmed by using historical calibration data and verification data. Based on the calibration performance of each calibration unit, the overall calibration performance of the automatic calibration line of the electricity meter can be analyzed.

[0061] Specifically, the verification unit of the automated verification line for electricity meters can store the verification data generated during the execution of experimental projects. The verification data generated during the execution of experimental projects can be stored in the verification unit of the electricity meter verification line. After the full-inspection mode verification task is completed, the verification terminal obtains the verification data and verification data from the management terminal according to the full-inspection mode verification task number and the verification electricity meter number. By analyzing the verification data and verification data and comparing them with historical verification data, the verification performance of each verification unit can be obtained. For example, all verification units have qualified basic errors, some verification units have qualified basic errors, or all verification units have unqualified basic errors. This allows for analysis of whether the verification performance of the automated verification line for electricity meters meets the requirements. For example, the test conclusion can be determined according to the requirements of industry regulations such as JJG597-2005 and JJG1085-2013, and the stability and equipment status of the automated verification line for electricity meters can be analyzed.

[0062] It should be noted that the verification data includes the meter address, specifications, model, task mode, task content, and test result data of the verification energy meter corresponding to the verification meter position; the verification data includes the test result data of the verification energy meter and the historical test result data.

[0063] Furthermore, in this embodiment, when the verification terminal receives a full-test mode verification task, it controls the verification of the electricity meter to be connected to at least one verification unit in the automated verification line of the electricity meter specified by the full-test mode verification task. The automated verification line of the electricity meter controls the verification unit to perform the test items of the full-test mode verification task. After the full-test mode verification task is completed, the verification terminal obtains the verification data of each verification position in the verification unit, as well as the verification data in the electricity meter, and analyzes the verification performance of the automated verification line of the electricity meter based on the verification data and the verification data. It can realize the verification of the verification performance of the verification position and the entire automated verification line of the electricity meter, which is fast, efficient, and does not affect the verification of ordinary electricity meters that need to be verified by other verification units in the automated verification line of the electricity meter.

[0064] It should be noted that when the verification terminal receives a full inspection mode verification task, before controlling at least one verification unit in the automatic verification pipeline of the electricity meter specified by the full inspection mode verification task, the following steps are also included: verifying whether the electricity meter being verified is an electricity meter undergoing a full inspection mode verification task;

[0065] Specifically, when the verification terminal receives a full inspection mode verification task, it scans the task identifier of the energy meter being verified. The task identifier can be a barcode. The terminal's display screen shows a prompt message indicating the current verification task mode of the scanned energy meter, prompting the user to confirm whether the energy meter is the one performing the verification task. In this embodiment, the current verification task mode is a full inspection mode verification task. After user confirmation, in response to the user's confirmation of the prompt message, the verification energy meter is confirmed to have passed device authentication, and the verification energy meter is controlled to enter the automated energy meter verification line, which can avoid verification equipment errors.

[0066] It should be noted that after confirming that the energy meter has passed device authentication, the verification terminal sets performance parameters corresponding to the test items for the energy meter, so that the energy meter can be verified through the test items to realize the verification of the automated verification line of the energy meter; the verification terminal also sets a whitelist of test items for the energy meter, which does not include destructive test items, so that the automated verification line of the energy meter controls the verification unit to execute the test items in the whitelist, shielding the destructive test items and avoiding test losses to the energy meter. The destructive test items include withstand voltage test and power consumption test;

[0067] Furthermore, when the number of energy meters being checked can only fill one tray of one verification unit at a time, after the verification of one verification unit is completed, these energy meters need to be returned to complete the verification of other verification units in a cycle. Therefore, the verification terminal also needs to set up the steps that need to be skipped for the energy meters in order to be smoothly transported to the next verification unit. The steps that can be skipped may include: appearance, keying, labeling and sealing.

[0068] It should be noted that the automated verification line for electricity meters automatically records the verification units that have completed the full-test mode verification task. Before step S202, when the automated verification line for electricity meters controls the verification units to perform the full-test mode verification task, it verifies whether the verification unit has already completed the verification task.

[0069] Specifically, the automated verification line for electricity meters searches for the verification unit's identifier in the recorded historical identifiers of the verification units. If the identifier is not found, it means that the verification unit has not performed a full-test mode verification task, and the line will control the verification unit to perform the full-test mode verification task test. If the identifier is found, it means that the verification unit has not performed a full-test mode verification task, and the line will not perform the full-test mode verification task test and will issue a prompt. The prompt can take the form of an alarm or sending a prompt message to the verification terminal.

[0070] In one feasible implementation, such as Figure 2 As shown, it includes the following steps:

[0071] S301: When the verification terminal receives a full inspection mode verification task, it controls at least one verification unit in the automatic verification line of the electricity meter specified by the full inspection mode verification task.

[0072] S302: After the test items of the full-test mode verification task of the automatic verification line control verification unit of the electricity meter are completed, the verification terminal obtains the verification data of each verification unit in the verification unit, as well as the verification data in the verification electricity meter.

[0073] S303. Analyze the verification performance of the automated verification line for electricity meters based on the verification data and check data.

[0074] It should be noted that the verification method of the above-mentioned automated verification line for electricity meters is based on the verification terminal as the main execution body. Figure 3 The technical details related to the verification terminal described in the illustrated embodiments are the same as those in this embodiment, and will not be repeated here;

[0075] It should be noted that the verification method for the automated verification line of electricity meters provided in this application embodiment involves the verification terminal receiving a full-test mode verification task. The terminal controls the verification unit to connect at least one verification unit in the automated verification line specified by the full-test mode verification task. The automated verification line controls the verification unit to perform the experimental items of the full-test mode verification task. After the full-test mode verification task is completed, the verification terminal obtains the verification data of each verification unit and the verification data in the verification electricity meter. Based on the verification data, the terminal analyzes the verification performance of the automated verification line. This method can verify the verification performance of the verification units and the entire automated verification line, achieving high speed and efficiency without affecting the verification of ordinary electricity meters by other verification units in the automated verification line.

[0076] Reference Figures 3-4 In another embodiment of the present invention, a verification system for an automated production line of electricity meters in full-test mode is provided, comprising:

[0077] Control module 401 is used to control at least one verification unit in the automatic verification line of the electricity meter specified by the verification terminal when the verification terminal receives the verification task of the full inspection mode.

[0078] The acquisition module 402 is used to acquire the verification data of each verification unit in the verification unit and the verification data in the electricity meter after the experimental project of the full inspection mode verification task in the control verification unit of the automatic verification line of the electricity meter is completed.

[0079] Analysis module 403 is used to analyze the verification performance of the automated verification line for electricity meters based on the verification data and check data;

[0080] It should be noted that the acquisition module 402 is also used to acquire verification data and inspection data from the management terminal, and the analysis module 403 is also used to analyze the verification performance of each verification station through the verification data and inspection data, and to analyze the overall verification performance of the automatic verification line of the electricity meter based on the verification performance of each verification station.

[0081] Specifically, the verification terminal also includes an identity verification module and a setting module. The identity verification module is used to scan the task identifier of the energy meter being verified when it receives a full inspection mode verification task, and displays a prompt message about the current verification task mode of the scanned energy meter. In response to the confirmation operation of the prompt message, it confirms that the energy meter has passed the device identity verification. The setting module is used to set the performance parameters corresponding to the test items for the energy meter being verified, and also to set a whitelist of test items for the energy meter being verified. The whitelist does not include destructive test items, so that the automated verification line of the energy meter controls the verification unit to execute the test items in the whitelist.

[0082] Furthermore, such as Figure 4 As shown, the verification system of the automated electricity meter production line under full inspection mode also includes: verification terminal 10 and verification electricity meter 20. Verification terminal 10 is connected to verification electricity meter 20 and automated electricity meter verification production line 30 via network.

[0083] It should be noted that the automated verification line 30 for electricity meters includes multiple verification units, each verification unit includes multiple verification positions, and each verification position can verify one verification electricity meter 20. The robot for loading the meter installs the verification electricity meter 20 into a tray, and the tray is transported to the verification unit. Each verification unit has a data storage function, which can store various data when performing the verification task. Each verification position has a pulse output interface for outputting high-frequency pulses.

[0084] It should be noted that the verification energy meter 20 can be a standard energy meter installed in a wall, specifically a single-phase or three-phase standard energy meter. The interfaces of single-phase and three-phase standard energy meters differ. In one example, the interface of a single-phase standard energy meter is the leftmost two terminals 5 and 6 (common terminals) of the auxiliary port, while the interface of a three-phase standard energy meter is the two terminals 13 and 15 (common terminals) of the auxiliary port. The terminal settings corresponding to these interfaces can be adjusted according to the actual structure of the verification meter position. Single-phase and three-phase standard energy meters can be collectively referred to as standard energy meters installed in a wall. The design functions and performance of the electricity meter must simultaneously comply with industry standards including GB / T17215.211 and GB / T17215.701, and can operate stably online for a long time under various complex field conditions; the accuracy class of the standard installed electricity meter is up to 0.02, with an ultra-wide dynamic measurement range of 0.05A-100A (0.02 class for single-phase standard installed electricity meters), 0.05A-100A (0.02 class for three-phase direct-connection standard installed electricity meters), and 0.01A-6A (0.02 class for three-phase inductive standard installed electricity meters); the three-phase standard installed meter is also compatible with both three-phase three-wire and three-phase four-wire modes.

[0085] Specifically, the verification of the electricity meter 20 can be carried out. It has metering function, storage function, measurement function, fault simulation function and communication function.

[0086] ① Metering function: Includes functions for measuring active and reactive power in both positive and reverse directions;

[0087] ② Storage function: All calibration error data can be stored independently through built-in large-capacity non-volatile memory;

[0088] ③ Measurement function: Built-in two error calculators with one-millionth accuracy for energy reading and calibration pulse. The three-phase standard energy meter can automatically measure the reading error, calibration pulse error and real-time power value of the meter under test. Built-in high-precision second signal source and error calculator for clock error comparison and daily timing error calculation.

[0089] ④ Fault simulation function: It can simulate the starting, creeping, basic error, daily timing error, demand indication error, time period switching, and communication failure required by the electricity meter verification regulations. The fault type can be set through the terminal equipment.

[0090] ⑤ Communication function: Supports communication via RS485, Bluetooth, Wi-Fi and other methods, enabling the verification energy meter 20 to communicate with other devices such as the verification terminal 10, send the stored data to the verification terminal 10, and also transmit the energy consumption, error data, load records and other data in the verification energy meter 20 to the verification terminal 10 or other related devices, master station, etc.

[0091] It should be noted that the verification terminal 10 is specifically a mobile terminal such as a mobile phone, and an electronic device such as a host computer; the verification terminal 10 is equipped with a client with control and setting functions. When the client is run, the display screen of the verification terminal 10 displays operation interfaces such as control interface and setting interface. The verification terminal 10 is used to set the parameters of the verification energy meter through the setting interface, and to obtain the verification data of each verification position in the verification unit and the verification data in the verification energy meter through the control interface.

[0092] It should be noted that the verification terminal 10 is used to control the verification energy meter 20 to be connected to at least one verification unit in the automated energy meter verification line 30 specified by the full-inspection mode verification task when receiving a full-inspection mode verification task; the verification terminal 10 is used to acquire the verification data of each verification position in the verification unit and the verification data in the verification energy meter 20 after the full-inspection mode verification task is completed, and to analyze the verification performance of the automated energy meter verification line 30 based on the verification data and the verification data; it is also used to acquire data from the management terminal. The system collects and verifies data, analyzes the verification performance of each verification station based on the verification data and verification data, and analyzes the overall verification performance of the automated verification line 30 for electricity meters based on the verification performance of each verification station; it is also used to scan the task identifier of the verification electricity meter 20 when a full-check mode verification task is received, and display the prompt information of the current verification task mode of the scanned verification electricity meter 20; and it is used to confirm the verification electricity meter 20 has passed the device authentication in response to the confirmation operation of the prompt information.

[0093] It should be noted that the automated verification line 30 for electricity meters is used to control the verification unit to perform experiments on the estimation of basic error and standard deviation; it is also used to search for the identifier of the verification unit in the recorded historical identifiers of the verification unit; if the identifier of the verification unit is not found, the verification unit is controlled to perform experiments on the full-test mode verification task; if the identifier of the verification unit is found, the verification unit is not subjected to experiments on the full-test mode verification task.

[0094] Specifically, the verification system for the automated energy meter verification line provided in this application embodiment, when the verification terminal receives a full-test mode verification task, controls the verification energy meter to be connected to at least one verification unit in the automated energy meter verification line specified by the full-test mode verification task. The automated energy meter verification line controls the verification unit to perform the experimental items of the full-test mode verification task. After the full-test mode verification task is completed, the verification terminal obtains the verification data of each verification position in the verification unit, as well as the verification data in the verification energy meter, and analyzes the verification performance of the automated energy meter verification line based on the verification data and the verification data.

[0105] Example 2

[0106] This embodiment differs from the first embodiment in that it provides a verification test of the verification method for the automated energy meter production line under full inspection mode. In order to verify and explain the technical effect of the method, this example selects an automated energy meter verification production line device in normal operation to carry out the periodic verification task, and uses a standard energy meter, terminal equipment and verification system to carry out the periodic verification in full inspection mode.

[0107] Taking a 72-position calibration unit of a 0.1-class single-phase energy meter automated sampling device as an example:

[0108] ① Install 36 standard energy meters into the first 36 positions of the current verification unit;

[0109] ② The electrical measurement system formulates a testing plan according to the requirements of the periodic verification task, and conducts tests on the basic error and standard deviation estimates in accordance with the test requirements specified in JJG597-2005 "Verification Procedure for AC Energy Meter Verification Device";

[0110] ③ The electrical testing system conducts verification tests according to the task requirements. All test items are carried out in a two-way testing mode (that is, the assembly line device tests the installed standard meter while also being tested as the device under test). After the verification is completed, the installed standard energy meter is transferred to the warehouse by the logistics system. The electrical testing system uploads the two-way verification data and conclusions of the verification unit to the data analysis system of the automated energy meter verification device, generates the verification conclusion, and issues a verification report and an interim verification report according to the given template. Finally, it determines whether the standard meter and meter position of the automated assembly line verification device are qualified, and extracts the verification data of meter position 1 of the verification unit, as shown in Table 1.

[0112]

[0113] As can be seen from the above, the present invention can realize the verification performance of the verification station and the entire automated verification line of electricity meters. It is fast, efficient, and does not affect the verification of ordinary electricity meters that need to be verified by other verification units in the automated verification line of electricity meters.
