Description

Technical Field

[0001] The invention relates to the field of electric energy meter verification, and in particular to a verification method for compatible single-phase electric energy meters and acquisition terminals. Background Art

[0002] In the electric energy metering industry, in order to ensure the accuracy and reliability of electric energy meters, power companies and electric energy meter manufacturers generally use electric energy meter automatic verification lines to perform electric energy meter verification work. According to the different types of electric energy meters, automatic verification lines are mainly divided into two categories: single-phase electric energy meter automatic verification lines and three-phase electric energy meter verification lines. As a key component of the verification line, the performance of the meter socket directly affects the efficiency and accuracy of the verification work.

[0003] The existing meter socket design is usually customized for a specific type of electric energy meter, for example, single-phase smart electric energy meter, three-phase direct-access smart electric energy meter, three-phase transformer-access smart electric energy meter and collection terminal, each with an independent meter socket. However, this design leads to the need to design and purchase corresponding meter sockets for different types of electric energy meters. In particular, when it is necessary to connect the auxiliary terminals on the socket, due to the lack of an avoidance mechanism, the outer shell of the electric energy meter itself can only withstand the connection pressure of the auxiliary terminals, which not only increases the complexity of the verification process, but may also cause potential damage to the socket and the electric energy meter.

[0004] Currently, there is no meter socket that can meet the compatibility requirements of single-phase energy meters and collection terminals. When it is necessary to calibrate single-phase energy meters and collection terminals, two different meter sockets need to be set up respectively, which is costly. Summary of the invention

[0005] The main purpose of the present invention is to propose a calibration method for compatible single-phase electric energy meters and collection terminals, aiming to simultaneously meet the compatibility requirements of single-phase electric energy meters and collection terminals, and has a simple structure, low material cost and beautiful appearance.

[0010] In some embodiments, the plurality of test groups include a first test group, a second test group, and a third test group, respectively, and the first test group, the second test group, and the third test group each include a plurality of test columns; the step of driving at least one test column in one of the test groups to move along the second direction to merge with another test group includes:

[0011] Driving at least one test column in the second test group to move toward the direction close to the first test group and to form a fourth test group together with the first test group;

[0012] At least one of the test columns in the second test group is driven to move toward the direction close to the third test group and together with the third test group form a fifth test group; wherein the remaining test columns of the second test group form a sixth test group.

[0013] In some embodiments, the step of driving the combined verification group to verify the acquisition terminal includes:

[0014] The fourth inspection group and the fifth inspection group are driven to inspect the two acquisition terminals.

[0015] In some embodiments, before the step of driving the fourth verification group and the fifth verification group to verify the two acquisition terminals, the following steps are also included:

[0016] Drive the sixth inspection group back to the non-inspection position.

[0017] In some embodiments, before the step of driving the fourth verification group and the fifth verification group to verify the two acquisition terminals, the following steps are also included:

[0018] Switching the relative positions of the verification columns in the fourth verification group so that the verification columns in the fourth verification group are adapted to the collection terminal;

[0019] The relative positions of the calibration columns in the fifth calibration group are switched so that the calibration columns in the fifth calibration group are adapted to the collection terminal.

[0020] In some embodiments, before the step of driving multiple calibration groups to calibrate multiple single-phase electric energy meters one by one, the multiple calibration columns in the first calibration group include multiple voltage columns and multiple current columns, each voltage column retreats to a non-calibration position, at least part of the current columns retreat to the non-calibration position, and multiple current columns are located in the calibration position; before the step of driving the fourth calibration group and the fifth calibration group to calibrate the two acquisition terminals, the following steps are also included:

[0021] The current columns in the fourth calibration group that are in the non-calibration position are driven to move to the calibration position.

[0022] In some embodiments, before the step of driving multiple calibration groups to calibrate multiple single-phase electric energy meters one by one, the multiple calibration columns in the third calibration group include multiple voltage columns and multiple current columns, each voltage column retreats to a non-calibration position, at least part of the current columns retreat to the non-calibration position, and multiple current columns are located in the calibration position; before the step of driving the fourth calibration group and the fifth calibration group to calibrate the two acquisition terminals, the following steps are also included:

[0023] The current column in the fifth calibration group that is in the non-calibration position is driven to move to the calibration position.

In the process of calibrating single-phase electric energy meters, the calibration columns in the calibration group are arranged in a first direction and can be moved in a second direction perpendicular to the first direction to achieve the merging or splitting of the calibration groups. When it is necessary to calibrate the collection terminal, the calibration column moves from the position of calibrating the single-phase electric energy meter and merges with other calibration groups to form a new calibration group to accommodate different interface configurations of the collection terminal. This design improves the flexibility of the calibration equipment, so that the same set of calibration equipment can serve multiple types of electric energy meters and collection terminals at the same time.

[0033] In addition, the technical solution of the present application makes full use of the calibration columns in some of the calibration groups. Compared with the solution in which all the probes in a group are gathered together and returned to the non-calibration position when calibrating the collection terminal, the calibration columns in a calibration group of the present application can be reused. Therefore, the technical solution of the present application can reduce the number of calibration columns, reduce material costs, and has a simple and beautiful structure.

[0086] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0087] Reference Fig.23 In some embodiments, the present application proposes a verification method for compatible single-phase electric energy meter 200 and acquisition terminal 300, characterized in that it includes the following steps:

[0088] S101: driving a plurality of calibration groups to calibrate a plurality of single-phase electric energy meters 200 one by one; wherein each calibration group comprises a plurality of calibration columns 120, each calibration column 120 extends along a first direction X, and each calibration column 120 is arranged along a second direction Y intersecting the first direction X;

[0089] S103: driving at least one inspection column 120 in one inspection group to move along the second direction Y to merge with another inspection group;

[0090] S105: driving the combined calibration group to calibrate the collection terminal 300; wherein the collection terminal 300 includes at least one of a concentrator, a special transformer terminal or an energy controller, and the number of the collection terminals 300 is less than the number of the single-phase electric energy meters 200.

[0091] Specifically, some calibration groups of the present application are designed to be able to be flexibly combined to accommodate the calibration of different numbers and types of electric energy meters and collection terminals 300. In the process of calibrating the single-phase electric energy meter 200, the calibration columns 120 in the calibration group are arranged in a first direction X, and can be moved along a second direction Y perpendicular to the first direction X to achieve the merging or splitting of the calibration groups. When it is necessary to calibrate the collection terminal 300, the calibration column 120 moves from the position of calibrating the single-phase electric energy meter 200, and is merged with other calibration groups to form a new calibration group to accommodate different interface configurations of the collection terminal 300. This design improves the flexibility of the calibration equipment, so that the same set of calibration equipment can serve multiple types of electric energy meters and collection terminals 300 at the same time.

[0092] The technical solution of the present application makes full use of the calibration column 120 in the second calibration group b. Compared with the solution in which all the probes in the second probe 171 group are gathered together and returned to the non-calibration position when calibrating the collection terminal 300, the calibration column 120 in the second calibration group b of the present application can be reused. Therefore, the technical solution of the present application can reduce the number of calibration columns 120, reduce material costs, and has a simple and beautiful structure.

[0093] It is understandable that in some embodiments, the movement of the calibration column 120 is achieved by a precise mechanical device, which can ensure that the calibration column 120 is accurately moved to the required calibration position. In addition, the design of the calibration column 120 takes into account the standard interfaces of different devices, and can quickly adapt to different types of electric energy meters and acquisition terminals 300 through adjustment, thereby improving the efficiency and accuracy of the calibration. Through the flexible combination of the calibration column 120, not only can the space occupied by the calibration equipment be saved, but also the degree of automation of the calibration process can be improved, manual intervention can be reduced, and the calibration efficiency can be improved.

[0094] In some embodiments, the plurality of test groups include a first test group a, a second test group b, and a third test group c, respectively. The first test group a, the second test group b, and the third test group c each include a plurality of test columns 120. The step of driving at least one test column 120 in one of the test groups to move along the second direction Y to merge with another test group includes:

[0095] Driving at least one test column 120 in the second test group b to move toward the direction close to the first test group a and forming a fourth test group d together with the first test group a;

[0096] At least one of the inspection columns 120 in the second inspection group b is driven to move toward the third inspection group c and together with the third inspection group c form a fifth inspection group e; wherein, the remaining inspection columns 120 in the second inspection group b form a sixth inspection group f.

[0097] Specifically, the calibration columns 120 in the second calibration group b can move toward the first calibration group a or the third calibration group c, and merge with them to form a new calibration group - the fourth calibration group d or the fifth calibration group e, which is used to calibrate different types of collection terminals 300. The calibration columns 120 that are not involved in the merger in the second calibration group b form the sixth calibration group f, which can be retracted to the non-calibration position when not needed to avoid interfering with the ongoing calibration operation. This dynamic adjustment method not only improves the flexibility of the calibration equipment, but also enables the same set of calibration equipment to adapt to the calibration needs of different numbers and types of electric energy meters and collection terminals 300.

[0098] It is understandable that, in some embodiments, the movement of the calibration column 120 and the combination of the calibration group are achieved through preset program control to ensure that the calibration column 120 can be accurately moved to the desired position and form a correct calibration group. In addition, the design of the calibration column 120 takes into account the standard interfaces of different devices, and can quickly adapt to different types of electric energy meters and acquisition terminals 300 through adjustment, thereby improving the flexibility and efficiency of the calibration. In this way, not only the calibration efficiency is improved, but also the quality of the calibration results is guaranteed, providing a strong guarantee for the stable operation of the power system.

[0099] In some embodiments, the step of driving the combined verification group to verify the acquisition terminal 300 includes:

[0100] The fourth inspection group d and the fifth inspection group e are driven to inspect the two acquisition terminals 300 .

[0101] The fourth verification group d and the fifth verification group e are formed by combining the second verification group b with other verification groups, and the verification columns 120 are recombined to form new verification groups, so as to adapt to different types of collection terminals 300. The fourth verification group d and the fifth verification group e are each responsible for the verification of one collection terminal 300, so that the verification efficiency is improved.

[0102] In specific principles, the purpose of merging the verification groups is to form a verification capability that can handle multiple acquisition terminals 300 at the same time. By adjusting the position and number of the verification columns 120, it can be ensured that each acquisition terminal 300 can be properly verified. The formation of the fourth verification group d and the fifth verification group e is actually to reasonably allocate verification resources according to the needs of different acquisition terminals 300 to achieve the best verification efficiency. This flexible allocation of verification resources makes the verification process not only efficient but also targeted.

[0103] Through the independent operation of the fourth calibration group d and the fifth calibration group e, two acquisition terminals 300 can be calibrated at the same time, which significantly improves the calibration efficiency, reduces the waiting time, and thus improves the overall calibration process efficiency.

[0104] It is understandable that in some embodiments, the fourth calibration group d and the fifth calibration group e may need to adjust the position of the calibration column 120 when they are combined to ensure that they can effectively calibrate the collection terminal 300. This adjustment may involve relative movement or rotation between the calibration columns 120 to ensure that the calibration columns 120 can properly contact the key parts of the collection terminal 300. In addition, the material and shape of the calibration column 120 also need to match the surface characteristics of the collection terminal 300 to ensure stability and accuracy during the calibration process. By adjusting the position and characteristics of the calibration column 120, it is possible to better adapt to the calibration requirements of different types of collection terminals 300 and ensure the accuracy of the calibration.

[0105] In some embodiments, before the step of driving the fourth verification group d and the fifth verification group e to verify the two acquisition terminals 300, the following steps are also included:

[0106] Drive the sixth inspection group f back to the non-inspection position.

[0107] When the fourth calibration group d and the fifth calibration group e begin to calibrate the acquisition terminal 300, the sixth calibration group f needs to exit the calibration area to avoid interfering with the ongoing calibration work.

[0108] In principle, the sixth test group f is retracted to avoid interference or obstruction during the work of the fourth test group d and the fifth test group e, ensuring the safety and effectiveness of the test process. By moving the no longer needed test groups out of the working area, the risk of accidental touch or collision can be reduced, while providing more operating space for the ongoing test.

[0109] The timely retreat of the sixth inspection group f effectively avoided unnecessary collision risks, provided a guarantee for the smooth progress of the inspection work, and improved the safety of the inspection work.

[0110] It is understandable that in some embodiments, speed control and path planning may be required during the retreat of the sixth verification group f to ensure that the retreat action is smooth and does not affect the ongoing verification work. In addition, the retreat of the sixth verification group f also involves spatial coordination with other verification groups to ensure that it does not conflict with the verification group in operation. Through precise speed control and path planning, the sixth verification group f can be effectively prevented from interfering with the verification environment during the retreat process, ensuring the safety and reliability of the entire verification process.

[0111] In some embodiments, before the step of driving the fourth verification group d and the fifth verification group e to verify the two acquisition terminals 300, the following steps are also included:

[0112] Switching the relative positions of the verification columns 120 in the fourth verification group d so that the verification columns 120 in the fourth verification group d are adapted to the collection terminal 300;

[0113] The relative positions of the inspection columns 120 in the fifth inspection group e are switched so that the inspection columns 120 in the fifth inspection group e are adapted to the collection terminal 300 .

[0114] In this embodiment, in order to enable the fourth inspection group d and the fifth inspection group e to accurately dock with the collection terminal 300 , it is necessary to adjust the position of the inspection column 120 so that it can match with different types of collection terminals 300 .

[0115] Specifically, the position of the calibration column 120 is adjusted to adapt to different interface specifications of the acquisition terminal 300. By adjusting the position of the calibration column 120, it can be ensured that the calibration column 120 can be accurately docked with each interface of the acquisition terminal 300, thereby ensuring the effectiveness and accuracy of the calibration process. This adjustment is usually completed through the automated control of the calibration system to ensure that the calibration column 120 is in the most appropriate relative position during each calibration.

[0116] By adjusting the position of the calibration column 120 , the compatibility of the calibration system can be improved, so that the same calibration device 100 can handle a variety of different types of acquisition terminals 300 , thereby reducing equipment costs and improving calibration efficiency.

[0117] It is understandable that, in some embodiments, the position of the calibration column 120 may need to be adjusted through a control system, and the control system automatically adjusts the position of the calibration column 120 according to the model of the acquisition terminal 300. In addition, the calibration column 120 may also need to have a certain degree of scalability or mobility so as to better adapt to the interfaces of different acquisition terminals 300. Through such a design, not only the flexibility of the calibration process can be improved, but also each calibration can be ensured to be completed efficiently and accurately.

[0118] In some embodiments, before the step of driving multiple calibration groups to calibrate multiple single-phase electric energy meters 200 one by one, the multiple calibration columns 120 in the first calibration group a include multiple voltage columns 123 and multiple current columns 124, each voltage column 123 retreats to a non-calibration position, at least part of the current columns 124 retreats to a non-calibration position, and multiple current columns 124 are located in the calibration position; before the step of driving the fourth calibration group d and the fifth calibration group e to calibrate the two acquisition terminals 300, the following steps are also included:

[0119] The current columns 124 in the fourth testing group d that are in the non-testing position are driven to move to the testing position.

[0120] In this embodiment, before the calibration group prepares to calibrate the acquisition terminal 300, it is necessary to move the current column 124 in the fourth calibration group d that is in the non-calibration position to the calibration position to ensure the smooth progress of the calibration process.

[0121] Specifically, the movement of the current column 124 is to ensure that the current column 124 can be correctly connected to the acquisition terminal 300 during the calibration process to ensure the effectiveness of the calibration. Through the control system command, the current column 124 can be moved from the non-calibration position to the calibration position, and this process is usually achieved by a precise mechanical transmission mechanism. Ensuring that all necessary current columns 124 are in the correct calibration position can improve the accuracy and consistency of the calibration.

[0122] By moving the current column 124 to the correct calibration position, it can be ensured that the acquisition terminal 300 can obtain sufficient current supply during calibration, so that the calibration result is more accurate and reliable.

[0123] It is understandable that in some embodiments, the movement of the current column 124 may involve a complex mechanical transmission design to ensure that the current column 124 can reach the calibration position smoothly and accurately. In addition, the control system may need to be closely integrated with the mechanical transmission part to ensure that the current column 124 can be quickly in place when needed. Through such a design, not only the stability of the calibration process can be improved, but also the consistency and accuracy of the calibration results can be ensured.

[0124] In some embodiments, before the step of driving multiple calibration groups to calibrate multiple single-phase electric energy meters 200 one by one, the multiple calibration columns 120 in the third calibration group c include multiple voltage columns 123 and multiple current columns 124, each voltage column 123 retreats to a non-calibration position, at least part of the current columns 124 retreats to a non-calibration position, and multiple current columns 124 are located in the calibration position; before the step of driving the fourth calibration group d and the fifth calibration group e to calibrate the two acquisition terminals 300, the following steps are also included:

[0125] The current column 124 in the fifth testing group e that is in the non-testing position is driven to move to the testing position.

[0126] In this embodiment, when the current columns 124 of the third calibration group c are calibrated for the electric energy meter, some of the current columns 124 are already in the calibration position, while the remaining current columns 124 are in the non-calibration position. When the acquisition terminal 300 is calibrated, it is necessary to move these current columns 124 in the non-calibration position to the calibration position to meet the calibration requirements of the acquisition terminal 300.

[0127] The specific principle is as follows: the movement of the current column 124 is to meet the calibration needs of different types of collection terminals 300. Since the interface position and number of the collection terminal 300 (such as a concentrator, a special transformer terminal or an energy controller) may be different from those of the electric energy meter, before the calibration, part of the current column 124 originally used for the electric energy meter calibration needs to be moved to the calibration position required by the collection terminal 300 to ensure the accuracy and reliability of the calibration. This movement can be achieved by servo motor drive or other forms of mechanical transmission to ensure that the current column 124 can be accurately positioned at the interface of the collection terminal 300.

[0128] By moving the current column 124 from the non-calibration position to the calibration position, the calibration device 100 can flexibly cope with different types of acquisition terminals 300, improve the compatibility and efficiency of the calibration, and also reduce the extra time and labor costs caused by equipment replacement.

[0129] It is understandable that in some embodiments, the operation of moving the current column 124 may involve a complex mechanical transmission system, including but not limited to components such as slide rails, guide rods, and lead screws. In addition, a control system is required to ensure that the current column 124 can be accurately moved to the desired position according to different models and interface configurations of the acquisition terminal 300. In this way, not only the automation of the verification process is improved, but also the consistency and accuracy of the verification results are guaranteed.

[0130] In some embodiments, before the step of driving multiple verification groups to verify multiple single-phase electric energy meters 200 one by one, the following steps are also included:

[0131] The first auxiliary probe set 160 is driven to be in the calibration position, and the second auxiliary probe set 170 is driven to be in the non-calibration position, so that the first auxiliary probe set 160 is suitable for calibrating each single-phase electric energy meter 200 .

[0132] In this embodiment, when the electric energy meter is calibrated, the first auxiliary probe set 160 needs to be placed in the calibration position, and the second auxiliary probe set 170 needs to be retracted to the non-calibration position to avoid interference with the calibration process.

[0133] The specific principle is as follows: the auxiliary probe group is designed to cooperate with the calibration process to ensure the accuracy of the calibration results. The first auxiliary probe group 160 needs to contact the electric energy meter during calibration to measure its performance indicators; while the second auxiliary probe group 170 should be away from the calibration area at this time to prevent it from having an adverse effect on the measurement results. This design can ensure that only the relevant probe group participates in the calibration work at different stages by controlling the movement of the probe group, thereby ensuring the accuracy and reliability of the calibration.

[0134] By distinguishing the working status of the auxiliary probe group, the verification process can be made more orderly and efficient, and the errors caused by auxiliary equipment can be reduced, thereby improving the accuracy and credibility of the verification.

[0135] It is understood that in some embodiments, the movement of the auxiliary probe group may involve complex control systems, including but not limited to servo motors, sensors, etc. Through these systems, the movement of the auxiliary probe group can be accurately controlled to ensure that it is in the right state at the right time. In addition, the durability and maintenance of the probe group must also be considered to ensure stability and life in long-term operation. In this way, the flexibility and adaptability of the verification system can be greatly improved to meet the verification needs in different occasions.

[0136] In some embodiments, after the step of driving multiple verification groups to verify multiple single-phase electric energy meters 200 one by one, the following steps are also included:

[0137] The first auxiliary probe group 160 is driven to be in a non-testing position, and the second auxiliary probe group 170 is driven to be in a test position, so that the second auxiliary probe group 170 is suitable for testing each acquisition terminal 300 .

[0138] In this embodiment, after multiple verification groups have completed verification of the single-phase electric energy meter 200, the switching of the auxiliary probe groups is used to prepare for the next verification of the acquisition terminal 300. The first auxiliary probe group 160 retreats to the non-verification position, while the second auxiliary probe group 170 moves to the verification position to ensure that they can adapt to the acquisition terminal 300 to be verified.

[0139] In specific principle, the switching of the auxiliary probe group is to provide appropriate calibration conditions at different calibration stages. By aligning the first auxiliary probe to the non-calibration position, it can prevent it from causing interference in the subsequent calibration process of the acquisition terminal 300; at the same time, the movement of the second auxiliary probe group 170 to the calibration position is to ensure that it can accurately dock with the interface of the acquisition terminal 300, so as to perform effective calibration.

[0140] By reasonably switching the auxiliary probe group, the switching time during the verification process can be effectively reduced, the verification efficiency can be improved, and the accuracy and reliability of the verification process can be ensured.

[0141] It is understood that in some embodiments, the movement of the second auxiliary probe group 170 may involve a translation mechanism on a mechanical arm or track to ensure that the probe group can be accurately positioned at the calibration position. In addition, the design of the probe group needs to take into account the interface compatibility with different types of acquisition terminals 300 (such as concentrators, special transformer terminals or energy controllers) to ensure the smooth progress of the calibration process. Through precise positioning and compatibility design, the flexibility and applicability of the calibration system can be greatly improved.

[0142] In some embodiments, the acquisition terminal 300 includes a concentrator, a dedicated transformer terminal, and an energy controller, and the step of driving a second auxiliary probe group 170 to be in a verification position includes:

[0143] Three second auxiliary probe groups 170 are provided, and the three second auxiliary probe groups 170 correspond to the verification concentrator, the dedicated transformer terminal and the energy controller respectively;

[0144] A corresponding one of the second auxiliary probe sets 170 is driven to move to the testing position.

[0145] In this embodiment, a dedicated second auxiliary probe group 170 is provided for different types of acquisition terminals 300 to ensure that the verification requirements of each type of acquisition terminal 300 can be adapted. When a specific type of acquisition terminal 300 needs to be verified, the corresponding second auxiliary probe group 170 is moved to the verification position.

[0146] In terms of specific principles, each second auxiliary probe group 170 is designed to match the characteristics of a specific type of acquisition terminal 300, and the corresponding auxiliary probe group is moved to the calibration position through the command of the control system. The purpose of this is to ensure that each acquisition terminal 300 can obtain the best contact conditions during calibration, thereby improving the accuracy of the calibration.

[0147] The beneficial effect is that by setting up a special second auxiliary probe group 170 for different types of acquisition terminals 300, the pertinence and efficiency of the calibration can be improved, the calibration error caused by equipment mismatch can be reduced, and the adaptability and reliability of the entire calibration system can be improved.

[0148] It is understandable that, in some embodiments, the movement and positioning of the second auxiliary probe group 170 may involve the coordinated work of the automatic control system and the mechanical transmission mechanism to ensure that the required probe group can be accurately moved to the verification position for each verification. In addition, the design of the probe group needs to consider the interface compatibility with the acquisition terminal 300 and the durability of the probe to ensure the stability and durability of the probe group during the verification process. Through such a design, the automation level of the verification system can be improved, manual intervention can be reduced, and the quality of each verification can also be ensured.

[0173] Specifically, the following examples are given to further illustrate the above method for easier understanding:

[0174] 1. Start: This step marks the beginning of the entire verification process.

[0175] 2. Prepare for the calibration of single-phase energy meter 200: In this step, all the calibration equipment and tools are ready, and the system is ready for the subsequent calibration of single-phase energy meter 200.

[0176] 3. The voltage column 123 of the first calibration group a is retracted: before starting to calibrate the single-phase electric energy meter 200, the voltage column 123 in the first calibration group a is retracted from the calibration position to the non-calibration position to make room for subsequent operations.

[0177] 4. Some current columns 124 in the first calibration group a retreat to the non-calibration position, and multiple current columns 124 are located at the calibration position: At this stage, some current columns 124 in the first calibration group a are moved to the non-calibration position, but some current columns 124 still remain at the calibration position for calibration work.

[0178] 5. The voltage column 123 of the third calibration group c retreats: The voltage column 123 associated with the third calibration group c also needs to retreat from the calibration position to the non-calibration position to avoid interfering with the work.

[0179] 6. Some current columns 124 of the third calibration group c retreat to the non-calibration position, and multiple current columns 124 are located at the calibration position: Similarly, in order to avoid interfering with the work, some current columns 124 in the third calibration group c will move to the non-calibration position, while other current columns 124 remain in the calibration position.

[0180] 7. The first auxiliary probe group 160 is in the calibration position: In order to calibrate the single-phase electric energy meter 200, the first auxiliary probe group 160 is moved to the calibration position where the calibration work can be performed.

[0181] 8. The second auxiliary probe set 170 is in a non-calibration position: In order not to interfere with the ongoing calibration of the single-phase electric energy meter 200, the second auxiliary probe set 170 is placed in a non-calibration position.

[0183] 10. Prepare for calibration of the data collection terminal 300: After completing the calibration of the single-phase energy meter 200, the system starts to prepare for the next calibration of the data collection terminal 300.

[0184] 11. Split the second inspection group b, and move a part of it toward the first inspection group a and merge with it to form a fourth inspection group d: Split a part of the inspection columns 120 from the second inspection group b, and move this part of the inspection columns 120 toward the first inspection group a, and merge with the first inspection group a to form a new fourth inspection group d.

[0185] 12. Another part of the second inspection group b moves toward the third inspection group c and merges with it to form the fifth inspection group e: the remaining inspection columns 120 of the second inspection group b move toward the third inspection group c and merge with the third inspection group c to form a new fifth inspection group e.

[0186] 13. The remaining inspection columns 120 form a sixth inspection group f and move back to the non-inspection position: the inspection columns 120 that did not participate in the merger in the second inspection group b form a new sixth inspection group f, and these inspection columns 120 are moved back to the non-inspection position.

[0187] 14. Adjust the positions of the calibration columns 120 in the fourth calibration group d and the fifth calibration group e to adapt to the acquisition terminal 300: In order to be able to calibrate the acquisition terminal 300, it is necessary to adjust the positions of the calibration columns 120 in the fourth and fifth calibration groups e.

[0188] 15. Move the current column 124 in the non-test position in the fourth test group d to the test position: move the current column 124 in the fourth test group d that was originally in the non-test position to the test position.

[0193] 20. Set up three second auxiliary probe groups 170, corresponding to the concentrator, special transformer terminal and energy controller respectively: In order to be able to calibrate different types of collection terminals 300 respectively, it is necessary to set up three second auxiliary probe groups 170 and match them with the corresponding types of collection terminals 300.

[0194] 21. Drive the corresponding second auxiliary probe group 170 to move to the verification position: move the second auxiliary probe group 170 corresponding to the specific acquisition terminal 300 type to the correct verification position.

[0195] 22. End: After completing all steps, the entire verification process ends.

[0196] Further, the following is an example of a verification device used in the present application, specifically, referring to Figure 1 , Fig.14 and Fig.16In some embodiments, the calibration device 100 includes a base 110 and a plurality of calibration columns 120. The base 110 is used to carry the calibration columns 120, which are respectively connected to the base 110 and extend along a first direction X, and are arranged in a second direction Y intersecting the first direction X. Specifically, in some embodiments, the first direction X and the second direction Y may be two directions intersecting each other in the same plane, for example, the first direction X and the second direction Y are two directions perpendicular to each other in a horizontal plane. In the first calibration state, each calibration column 120 together forms a first calibration group a, a second calibration group b, and a third calibration group c arranged along the second direction Y. These three calibration groups are used to calibrate three single-phase electric energy meters 200. When switched to the second calibration state, the calibration columns 120 are rearranged into a fourth calibration group d, a fifth calibration group e, and a sixth calibration group f, wherein the fourth calibration group d and the sixth calibration group f are used to calibrate two acquisition terminals 300. Specifically, at least one calibration column 120 in the second calibration group b can move toward the first calibration group a to form a new fourth calibration group d together with the first calibration group a; or, at least one calibration column 120 in the second calibration group b can also move toward the third calibration group c to form a new sixth calibration group f together with the third calibration group c.

[0197] On the one hand, this structural design allows the calibration device 100 to flexibly adjust its internal layout to adapt to different types of devices to be calibrated. By moving the calibration column 120 on the base 110, the calibration conversion from a single-phase electric energy meter 200 to a three-phase electric energy meter or other equipment is realized. This not only improves the applicability of the calibration device 100, but also reduces the time required to replace the calibration equipment, thereby improving the overall work efficiency.

[0198] On the other hand, the calibration device 100 of the present application makes full use of the calibration columns 120 in the second calibration group b. Compared with the solution in which all the probes in the second probe 171 group are gathered together and returned to the non-calibration position when calibrating the three-phase electric energy meter, the calibration columns 120 in the second calibration group b of the present application can be reused. Therefore, the calibration device 100 of the present application can reduce the number of calibration columns 120, reduce material costs, and has a simple and beautiful structure.

[0199] It can be understood that the extension direction of the calibration column 120 is the first direction X, that is, the first direction X is the axial direction of the calibration column 120, so when the calibration column 120 calibrates the single-phase electric energy meter 200 or the acquisition terminal 300, the calibration column 120 is extended and retracted along its own axial direction to insert the single-phase electric energy meter 200 or the acquisition terminal 300, and completes the calibration of the single-phase electric energy meter 200 or the acquisition terminal 300. When the calibration column 120 needs to be converted to adapt to the single-phase electric energy meter 200 or the acquisition terminal 300, the calibration column 120 moves along the second direction Y, and each independent calibration column 120 moves a different distance along the second direction Y, and some calibration columns 120 are gathered together to form the aforementioned calibration groups. The clustering here is only a description of the positional relationship of the calibration columns 120, which is intended to reflect this modular grouping method. There is no restriction on whether the spacing between the calibration columns 120 in the same group should be smaller than the spacing between different groups. That is, the spacing between two calibration columns 120 in the same group can be larger than the spacing between two adjacent groups, or smaller than the spacing between two adjacent groups.

[0200] Of course, it is understandable that after the calibration columns 120 are grouped, all the calibration columns 120 in the same group can participate in the calibration work of the single-phase electric energy meter 200 or the collection terminal 300, or only some of the calibration columns 120 can participate in the calibration work of the single-phase electric energy meter 200 or the collection terminal 300. Whether the calibration columns 120 themselves need to participate in the actual work does not affect the division of their groups in this application. This application is intended to indicate that by classifying the calibration columns 120 into different groups, the calibration device 100 can adapt to the single-phase electric energy meter 200 and the collection terminal 300 at the same time by converting the grouping structure. As for whether all the classified calibration columns 120 participate in the work, this application does not restrict it. It is only necessary that the calibration device 100 can successfully calibrate the single-phase electric energy meter 200 and the collection terminal 300. For example, in some embodiments, only some of the calibration columns 120 in the same group participate in the work, and it is only necessary that the calibration columns 120 not participating in the work do not interfere with the calibration of the single-phase electric energy meter 200 or the collection terminal 300 by other calibration columns 120 .

[0201] Of course, it is understandable that the present application divides the calibration column 120 into a first calibration group a, a second calibration group b, and a third calibration group c, so that the calibration device 100 can calibrate the single-phase electric energy meter 200. Then for multiple single-phase electric energy meters 200, based on the design concept of the present application, more calibration groups can be set up so that the calibration device 100 of the present application can calibrate more single-phase electric energy meters 200 at the same time. Furthermore, for single-phase electric energy meters 200 of different specifications, for example, for single-phase electric energy meters 200 of different specifications with different socket arrangement positions and different numbers of sockets for matching the calibration column 120, the present application can adapt to single-phase electric energy meters 200 of different specifications by adjusting the position of the calibration column 120 in each group. Specifically, for the single-phase electric energy meter 200 of the original specifications, the calibration columns 120 in the first calibration group a are arranged in the original arrangement. After switching to the single-phase electric energy meter 200 of the new specifications, the calibration columns 120 in the first calibration group a are arranged in a new arrangement, for example, the calibration columns 120 in the first calibration group a are controlled to move along the second direction Y respectively to adjust the distance between each other, so as to adapt to the interface of the single-phase electric energy meter 200 of the new specifications. Of course, in the case where the number of interfaces of single-phase electric energy meters 200 of different specifications changes, the structure of the first calibration group a can also be adjusted by adding calibration columns 120 to the first calibration group a or reducing calibration columns 120 to adapt. Of course, it can be understood that according to the previous embodiment, the first calibration group a can also be configured so that only part of the calibration columns 120 participate in the work, and the remaining calibration columns 120 that do not participate in the work do not interfere with the actual work of the calibration device 100. The above content takes the structural changes of the first calibration group a as an example. As for the second calibration group b and the third calibration group c, in actual operation, the concept of their structural adjustment is similar to that of the first calibration group a, and will not be repeated here. Of course, the situation in which the calibration device 100 handles the acquisition terminal 300 is similar to the situation in which it handles the single-phase electric energy meter 200, and will not be repeated here.

[0202] In summary, it can be understood that the first calibration state can be used to calibrate different types of single-phase electricity meters, for example, single-phase electricity meters with multiple specifications and multiple interfaces; the second calibration state can be used to calibrate different types of three-phase electricity meters or acquisition terminals, for example, three-phase electricity meters with multiple specifications and multiple interfaces.

[0203] Of course, based on the design principles of the present application, the calibration device of the present application is not limited to including only the first calibration group a, the second calibration group b, the third calibration group c, etc., but can also include multiple calibration groups, wherein one of the multiple calibration groups is configured to be split and thus integrated into other calibration groups to calibrate different devices to be calibrated.

[0204] It is understandable that, in some embodiments, in order to further improve the flexibility of the calibration device 100, the calibration column 120 can also be configured to be able to perform more precise position adjustment on the base 110. For example, the calibration column 120 can be installed on the base 110 through a precision guide rail or a slider system, so that the relative position between the calibration columns 120 can be more accurately controlled. In addition, an automated control system can be introduced to automatically adjust the position of the calibration column 120, so that the operator can complete the state switching of the calibration device 100 more quickly and conveniently. Such an expansion not only increases the convenience of operation of the calibration device 100, but also ensures the accuracy and repeatability of the calibration process, thereby enhancing the reliability of the entire calibration system. In addition, considering the diversity in actual applications, in order to facilitate the calibration column 120 to be compatible with various specifications of the devices to be calibrated, the calibration column 120 itself may also have certain adjustment functions, such as adjustable length or adjustable angle, so as to better fit the various different dimensions of the devices to be calibrated.

[0205] Reference Fig.16 and Fig.17 In some embodiments, the first calibration group a, the second calibration group b and the third calibration group c are all configured to be suitable for calibrating single-phase electric energy meters. The spacing, height and other relevant parameters of the calibration columns 120 in each calibration group are adaptively designed to ensure that they can accurately contact and test the various performance indicators of the single-phase electric energy meter. In addition, the fourth calibration group d and the sixth calibration group f are specially configured to calibrate other types of electrical products, such as three-phase electric energy meters, special transformer collection terminals or concentrators. When calibrating special transformer collection terminals, two rows of auxiliary probes can be designed. Please refer to Fig.16 , Fig.19 as well as Fig. 20 For such devices, the distance between the calibration columns 120, the arrangement and the positions of the supporting points are adjusted accordingly to meet the physical characteristics and electrical requirements of different products.

[0206] Such a configuration ensures that the calibration device 100 can not only handle common single-phase energy meters, but also can efficiently and accurately detect more complex multi-phase energy meters and other power management equipment. By adjusting and optimizing the position of the calibration column 120 and their mutual relationship, the calibration device 100 of the present application can provide a wide range of applications while maintaining high accuracy, greatly reducing the need for users to purchase additional calibration equipment in different application scenarios.

[0207] It is understandable that in some embodiments, in order to increase the versatility and adaptability of the calibration device 100, in addition to the specific configurations mentioned above, a modular design concept can also be adopted. That is, each calibration column 120 can be quickly disassembled and reorganized according to actual needs, and can even be equipped with different types of probes or sensors to support the calibration of more types of electrical equipment. For example, if a three-phase electric energy meter of a special model is to be calibrated, it is only necessary to replace the corresponding special calibration component. Similarly, for more special power management units such as special transformer acquisition terminals or concentrators, exclusive calibration modules can also be developed to ensure that each device can obtain the most suitable test conditions. This method not only simplifies the calibration process, but also greatly facilitates the user's daily maintenance work and extends the overall service life of the calibration device 100. In addition, the design of the calibration device 100 should also leave enough room for upgrading so that new functions can be added or existing mechanisms can be improved at any time to maintain its long-term competitiveness.

[0208] Reference Figure 4 In some embodiments, the calibration device 100 further includes a first drive assembly 130, which is connected to the base 110. The first drive assembly 130 is designed to drive at least one calibration column 120 in the second calibration group b, so that these calibration columns 120 can move relative to the base 110 along the second direction Y. Specifically, when it is necessary to switch from the first calibration state to the second calibration state, the first drive assembly 130 can push one or more calibration columns 120 in the second calibration group b toward the first calibration group a to form a fourth calibration group d together with the first calibration group a; or, it can also push one or more calibration columns 120 in the second calibration group b toward the third calibration group c to form a sixth calibration group f together with the third calibration group c.

[0209] Through this structural setting, the calibration device 100 can flexibly adjust the position of the calibration column 120, thereby achieving adaptability to different types of devices to be tested. Such a mechanism not only simplifies the operation process, but also improves the efficiency and accuracy of the calibration process. Since the calibration column 120 can be accurately controlled by the drive component, it can be ensured that the calibration column 120 is in the best position each time the calibration is performed, thereby ensuring the consistency and reliability of the calibration results.

[0210] It is understandable that in some embodiments, in order to improve the accuracy and stability of the movement of the calibration column 120, the first drive component 130 may also include additional positioning sensors and feedback control systems. For example, a position sensor can be installed on the calibration column 120, and the position of the calibration column 120 can be monitored and adjusted in real time through a closed-loop control system. In addition, the drive component itself can also adopt more advanced technologies, such as servo motors, linear actuators, etc., to provide smoother and more precise motion control. This can not only reduce mechanical wear and extend the life of the equipment, but also maintain high performance in complex and changing working environments. At the same time, taking into account the various situations that may be encountered in actual applications, the design of the drive component also needs to have certain fault detection and self-diagnosis capabilities, so as to quickly identify problems and take corresponding measures to further improve the reliability and user-friendliness of the system.

[0211] In some embodiments, the first driving component 130 is specially configured to drive at least one of the second testing group b near the first testing group a, and / or at least one of the testing columns 120 near the third testing group c. This means that the first driving component 130 can selectively drive the testing columns 120 at specific positions according to actual needs, thereby achieving more sophisticated and efficient reorganization of the testing groups.

[0212] In this way, the calibration device 100 can flexibly adjust its internal layout under different calibration states. For example, when it is necessary to switch from the first calibration state to the second calibration state, the first drive component 130 can selectively drive one or more calibration columns 120 in the second calibration group b close to the side of the first calibration group a, so that it moves and combines with the first calibration group a to form a new fourth calibration group d. Similarly, the first drive component 130 can also selectively drive one or more calibration columns 120 in the second calibration group b close to the side of the third calibration group c, so that it moves and combines with the third calibration group c to form a new sixth calibration group f.

[0213] This selective driving mechanism allows the calibration device 100 to perform a more customized calibration group configuration according to the specific type and size of the device to be tested. This not only improves the flexibility of the calibration process, but also enhances the accuracy and reliability of the calibration results. By accurately controlling the position of the calibration column 120, the calibration device 100 can better adapt to various different calibration requirements and improve the efficiency of the entire calibration process.

[0214] Further, in some embodiments, the first drive assembly 130 is configured to drive the calibration column 120 along a straight line; in some embodiments, the first drive assembly 130 is configured to drive the calibration column 120 along a curve. Driving along a straight line is simple and direct, easy to design, and efficient; driving along a curve can avoid obstacles to ensure smooth movement of the calibration column 120. The present application does not limit the movement trajectory of each calibration column 120, and it is sufficient to drive the corresponding calibration column 120 to a preset position in a certain way.

[0215] In some embodiments, the first drive assembly 130 is not required, and the operator configures the position of each calibration column 120 by manual adjustment. For example, a calibration column 120 in the second calibration group b is unplugged, and then inserted into the area where the first calibration group a is located, so as to be recombined with the original first calibration group a to form a third calibration group c.

[0216] It is understandable that in some embodiments, in order to enhance the selectivity and controllability of the first drive component 130, an intelligent control algorithm can also be introduced. For example, through a preset program logic or self-learning algorithm, the drive component can automatically identify the needs of the current calibration task, and decide which calibration columns 120 need to be moved and how to move them accordingly. In addition, the drive component can also be equipped with a variety of drive modes, such as manual mode, semi-automatic mode and fully automatic mode, to meet the requirements of different operators and technical levels. This intelligent design not only simplifies the operation process, but also greatly reduces the possibility of human error and improves overall work efficiency. At the same time, in order to cope with possible abnormal situations, the drive component can also integrate safety protection mechanisms, such as overload protection, emergency stop and other functions to ensure the safety and stability of equipment operation.

[0217] In some embodiments, the first driving assembly 130 includes a first driving cylinder 131 and a driving plate 132. The first driving cylinder 131 is connected to the base 110, and the driving plate 132 is connected to the first driving cylinder 131. The first driving cylinder 131 is configured to be able to drive the driving plate 132 to move along the first direction X. A plurality of driving holes 1321 are provided on the driving plate 132, and these driving holes 1321 extend obliquely relative to the first direction X and are arranged along the second direction Y. Each calibration column 120 includes a detection end 121 and a driving end 122, and at least part of the driving end 122 is provided with a driving protrusion, and these driving protrusions extend into the driving hole 1321 one by one. When the driving plate 132 translates along the first direction X, the corresponding calibration column 120 can translate along the second direction Y through the cooperation between the driving hole 1321 and the driving protrusion.

[0218] This structural design allows the calibration column 120 to move precisely laterally on the base 110, thereby achieving conversion between different calibration groups. Since the drive hole 1321 is inclined, when the drive plate 132 moves along the first direction X, the drive hole 1321 will drive the calibration column 120 to move along the second direction Y, forming a mechanical linkage mechanism. This not only improves the flexibility of the calibration device 100, but also ensures the accuracy and consistency during the calibration process. In addition, the inclination angle and layout of the drive hole 1321 have been carefully designed to ensure that the calibration column 120 can be accurately aligned at the required position for efficient calibration operations.

[0219] It is understood that, in some embodiments, in order to further improve the stability and accuracy of the movement of the calibration column 120, a guide groove or a guide rail can be provided on the drive plate 132 to limit the motion trajectory of the drive plate 132 in the first direction X. At the same time, the internal shape of the drive hole 1321 can also be designed as a specific profile, such as a V-shape, a U-shape or other shapes, to better guide the movement of the drive protrusion, reduce friction and improve positioning accuracy. In addition, a rolling element (such as a ball) can be used between the drive hole 1321 and the drive protrusion to reduce the wear of the contact surface and extend the service life. In addition, considering the various working conditions that may exist in actual applications, the design of the drive plate 132 and the drive hole 1321 also needs to have a certain rigidity and strength to withstand frequent operations without deformation. Finally, in order to facilitate maintenance and adjustment, the drive plate 132 can be designed to be detachable, which is convenient for replacing or cleaning impurities in the drive hole 1321.

[0220] Reference Fig.11 In some embodiments, the driving hole 1321 is composed of two connected parts: a first hole section 13211 and a second hole section 13212. The first hole section 13211 is located on a side close to the detection end 121, and the second hole section 13212 is located on a side away from the detection end 121. The first driving cylinder 131 is configured to drive the driving plate 132 to move from a first position to a second position, so that the driving protrusion moves from the end of the first hole section 13211 away from the second hole section 13212 to the end close to the second hole section 13212. In addition, the first driving assembly 130 also includes a second driving cylinder 133, which is also connected to the base 110 and is configured to drive the driving plate 132 to move from the second position to a third position, so that the driving protrusion moves from the end of the first hole section 13211 close to the second hole section 13212 to the end of the second hole section 13212 away from the first hole section 13211.

[0221] This dual-stage drive design allows the calibration column 120 to achieve a longer distance displacement through two-step movement while maintaining high accuracy. First, the first drive cylinder 131 pushes the drive plate 132 to the middle position (i.e., the second position), at which time the drive protrusion has partially entered the second hole section 13212; then, the second drive cylinder 133 continues to push the drive plate 132 to the final position (i.e., the third position), so that the drive protrusion completely enters the second hole section 13212. This staged drive mechanism avoids the instability factors that may be caused by a single large-scale movement, and also simplifies the complexity of the drive system.

[0222] It can be understood that the two cylinders are divided into two drive cylinders, so that both cylinders only need to move from the maximum stroke position to the minimum stroke position. Compared with setting up other single drive components that can stay at any intermediate position, the cost of setting up two cylinders for driving is lower.

[0223] It is understood that in some embodiments, in order to further optimize the driving process, the inclination angles of the first hole segment 13211 and the second hole segment 13212 can be designed to be different values. For example, the inclination angle of the first hole segment 13211 can be smaller to provide a smoother transition during the initial movement; while the inclination angle of the second hole segment 13212 can be larger to achieve a faster movement speed. Such a design not only ensures the stability of the initial stage, but also improves the efficiency of the subsequent stages. In addition, in order to enhance the reliability and durability of the entire drive system, the selection of the drive cylinder is also very important, and pneumatic components with high response speed and good durability can be selected. At the same time, in order to ensure the straightness and stability of the drive plate 132 throughout the stroke, a linear guide or slider system can be introduced to assist support and guidance. Finally, considering the maintenance problem after long-term use, the connecting parts between the drive cylinder and the drive plate 132 should be designed to be easy to disassemble and replace for regular inspection and maintenance.

[0224] In some embodiments, specifically, along the first direction X, the first hole segment 13211 and the second hole segment 13212 have different inclination angles. This design enables the driving plate 132 to guide the calibration column 120 to perform more complex and precise position adjustment through the hole segments with different inclination angles when moving along the first direction X.

[0225] Specifically, when the drive plate 132 moves from the first position to the second position, the drive protrusion will move along the first hole segment 13211. Due to the inclination angle of the first hole segment 13211, the calibration column 120 will gradually move toward the predetermined position along the second direction Y. Then, when the drive plate 132 continues to move from the second position to the third position, the drive protrusion enters the second hole segment 13212. Since the inclination angle of the second hole segment 13212 is different from that of the first hole segment 13211, this will cause the calibration column 120 to continue to move along the second direction Y at a different rate or trajectory, and finally reach the desired precise position. Such a structural design not only improves the positioning accuracy of the calibration column 120, but also allows the calibration device 100 to adapt to a more diverse layout of the device to be calibrated.

[0226] It is understandable that in some embodiments, in order to further improve the flexibility of the drive hole 1321 to adjust the position of the calibration column 120, multiple groups of first hole segments 13211 and second hole segments 13212 with different inclination angles can be designed. For example, several groups of hole segments with different angles can be set, and each group of hole segments corresponds to a specific type of device to be tested, so that a suitable angle combination can be selected according to actual needs to drive the calibration column 120. In addition, a sensor can be introduced to monitor the position of the drive protrusion in the hole segment, and the action of the drive cylinder can be adjusted in real time through the control system to achieve more precise control. In addition, considering the problem that long-term use may cause wear of the hole segment, the inner surface of the hole segment can be coated with a wear-resistant material or a self-lubricating material can be used to extend the service life and maintain good motion performance. Finally, in order to simplify maintenance work, the design of the drive plate 132 and the hole segment should be easy to disassemble and replace for regular inspection and cleaning.

[0227] It is understandable that, in some embodiments, the inclination angles of the first hole segment 13211 and the second hole segment 13212 may also be set to be the same, and the first hole segment 13211 and the second hole segment 13212 cooperate together to enable the calibration column 120 to reach the expected position.

[0228] Reference Fig.10 In some embodiments, the plurality of calibration columns 120 include a plurality of voltage columns 123. These voltage columns 123 can move along the first direction X on the base 110. In the first calibration state, each voltage column 123 is configured to be able to move to a first non-calibration position along the first direction X relative to the base 110; and in the second calibration state, each voltage column 123 is configured to be able to move to a first calibration position along the first direction X to calibrate the acquisition terminal 300. Such a design allows the voltage column 123 to flexibly adjust its position according to different calibration requirements, thereby ensuring the effectiveness and accuracy of the calibration process.

[0229] In this way, the voltage column 123 can be moved to a suitable non-testing position without interfering with other test operations, avoiding unnecessary electrical connections, and quickly and accurately reaching the specified position when a test is required. This mobility not only increases the operational flexibility of the test device 100, but also improves the overall work efficiency.

[0230] It is understood that in some embodiments, in order to enhance the stability and controllability of the movement of the voltage column 123, a guide rail or a slide groove is provided on the base 110 to ensure that the voltage column 123 moves smoothly and accurately along the first direction X. In addition, each voltage column 123 can be equipped with an independent driving mechanism, such as a micro motor or a linear actuator, and its movement can be accurately controlled by an electronic control system. In this way, not only can the independent control of a single voltage column 123 be achieved, but also the coordinated action of multiple voltage columns 123 can be synchronously controlled to meet complex verification requirements. In addition, in order to ensure electrical safety, the moving path of the voltage column 123 should be designed to be far enough to prevent accidental contact with the device to be verified or other components in a non-verification state. At the same time, limit devices can be set at both ends of the moving path of the voltage column 123 to prevent exceeding the preset range and ensure the safety of the operation of the equipment. Finally, considering the reliability of long-term use, the voltage column 123 and its driving components should be made of high-quality materials and undergo appropriate protective treatment to resist the influence of environmental factors.

[0231] Reference Figure 6 In some embodiments, the calibration device 100 further includes a second drive assembly 140, which is connected to the base 110 and each voltage column 123. The second drive assembly 140 is designed to drive each voltage column 123 to move relative to the base 110 along the first direction X, so that it can move from the first non-calibration position to the first calibration position, or vice versa. When in the first calibration state, each voltage column 123 will move to the first non-calibration position to avoid interfering with other calibration operations; and when it is necessary to switch to the second calibration state, these voltage columns 123 will be driven to the first calibration position to accurately test the electrical performance of the acquisition terminal 300.

[0232] Through such a structural setting, the calibration device 100 can flexibly adjust the position of the voltage column 123 under different conditions, so as to adapt to different types and specifications of devices to be tested. This automated displacement mechanism not only improves the efficiency of the calibration process, but also ensures that the voltage column 123 is in the best working position during each calibration, thereby improving the consistency and reliability of the calibration results.

[0233] It is understandable that the second drive assembly 140 can be configured to be manually driven, or mechanically driven, for example, the driving operation of the second drive assembly 140 is achieved by a back-pull cylinder.

[0234] It is understandable that in some embodiments, in order to further improve the accuracy and stability of the positioning of the voltage column 123, the second drive component 140 can use a high-precision linear actuator or servo motor and be equipped with a closed-loop control system. For example, a position sensor can be installed on the voltage column 123 to feed back its current position information to the controller in real time, and accurate position adjustment can be achieved through a PID control algorithm. In addition, taking into account various environmental factors in actual applications, such as temperature changes, mechanical wear, etc., a self-calibration function can also be added to the system to automatically check and adjust the position deviation of the voltage column 123 on a regular basis to ensure accuracy during long-term use. At the same time, in order to simplify maintenance and troubleshooting, the design of the drive component should consider modularization to facilitate rapid replacement of damaged parts and reduce downtime.

[0235] Reference Figure 6 In some embodiments, the multiple calibration columns 120 further include multiple current columns 124. In addition to the voltage column 123, the calibration device 100 further includes a third drive component 150, which is connected to the base 110 and at least part of the current columns 124. The third drive component 150 is configured to drive these current columns 124 to move relative to the base 110 along the first direction X, so that they can move from the second non-calibration position to the second calibration position, or vice versa. In the first calibration state, the current column 124 is usually located in the second non-calibration position and does not participate in the calibration process; in the second calibration state, the current column 124 will be moved to the second calibration position to perform necessary current detection on the acquisition terminal 300.

[0236] In this way, the current column 124 can flexibly change its position according to actual needs, thereby supporting different types of electrical performance tests. This dynamic adjustment capability enables the verification device 100 to better adapt to a variety of verification tasks, improving the versatility and flexibility of the device.

[0237] It is understandable that the third driving assembly 150 can be configured to be manually driven, or mechanically driven, for example, by a back-pull cylinder to achieve the driving operation of the third driving assembly 150 .

[0238] It is understood that in some embodiments, in order to ensure the stability and accuracy of the current column 124 during movement, the third drive component 150 can also use a precision linear actuator or servo motor, and combine sensor technology to achieve closed-loop control. For example, the movement trajectory of the current column 124 can be monitored by a displacement sensor installed on the current column 124, and a microprocessor can be used for data processing and control instruction generation, so as to achieve highly accurate position control. In addition, considering the electromagnetic interference problem that may exist in the current detection process, the current column 124 and its drive component should take appropriate shielding measures to ensure the stability and accuracy of signal transmission. In addition, in order to extend the service life, the sliding contact surface between the current column 124 and the base 110 can be made of wear-resistant material and lubricated regularly to reduce friction loss. Finally, in order to cope with possible abnormal situations, the third drive component 150 can also integrate safety protection mechanisms, such as overload protection, emergency stop and other functions, to ensure the safety and reliability of equipment operation.

[0239] Reference Figures 6 to 9 In some embodiments, the calibration device 100 further includes a first auxiliary probe group 160 and a second auxiliary probe group 170. Both groups of auxiliary probes are movably connected to the base 110. The first auxiliary probe group 160 includes a plurality of first probes 161 arranged along the second direction Y, and the second auxiliary probe group 170 includes a plurality of second probes 171 arranged along the second direction Y. In the first calibration state, the first auxiliary probe group 160 will slide relative to the base 110 along the first direction X to the third calibration position so as to calibrate the three single-phase electric energy meters 200; at the same time, the second auxiliary probe group 170 will move to the third non-calibration position and will not participate in the current calibration process. In the second calibration state, the second auxiliary probe group 170 will move to the fourth calibration position for calibrating the two acquisition terminals 300; at this time, the first auxiliary probe group 160 will move to the fourth non-calibration position.

[0240] Through this configuration, the auxiliary probe group can flexibly switch between different test states, ensuring that it can accurately contact the key points of the device to be tested each time, thereby improving the accuracy of the test results. In addition, such a design also simplifies the operation process of the test device 100, reduces the need for manual intervention, and improves the overall work efficiency.

[0241] It is understandable that in some embodiments, in order to further enhance the flexibility and accuracy of the auxiliary probe group, a precision guide rail or slider system can be provided between the auxiliary probe group and the base 110 to ensure smooth and precise movement. In addition, the auxiliary probe group can be equipped with an independent drive mechanism, such as a micro motor or a linear actuator, and automatic control can be achieved through an electronic control system. In this way, not only the independent movement of a single probe group can be achieved, but also the coordinated action between the two groups of probes can be coordinated to meet the needs of complex verification tasks. In addition, considering the reliability of long-term use, the auxiliary probe group and its related components should be made of high-quality materials, and appropriate protective measures should be taken to resist the influence of environmental factors. Finally, in order to facilitate maintenance and troubleshooting, the design of the auxiliary probe group should be easy to disassemble and replace to reduce downtime.

[0242] In some embodiments, the first auxiliary probe group 160 and the second auxiliary probe group 170 are arranged along a third direction Z, which intersects the first direction X and the second direction Y respectively. The verification device 100 also includes a fourth drive assembly 180, which is composed of a first double-piston rod double-linked cylinder 181 and a second double-piston rod double-linked cylinder 182. The two double-piston rod double-linked cylinders are arranged at intervals along the second direction Y, and each cylinder includes two piston rods, which move in opposite directions, so that the auxiliary probe groups can be effectively driven to switch between different positions.

[0243] Specifically, the first double piston rod double linkage cylinder 181 includes a first piston rod 1811 and a second piston rod 1812 arranged along the third direction Z. The first piston rod 1811 is connected to one side of the first auxiliary probe group 160 along the second direction Y, and the second piston rod 1812 is connected to one side of the second auxiliary probe group 170 along the second direction Y. When the first piston rod 1811 is pushed forward, the second piston rod 1812 will pull backward, and vice versa. This enables the first auxiliary probe group 160 and the second auxiliary probe group 170 to move synchronously but in opposite directions, thereby achieving rapid position conversion.

[0244] Similarly, the second double-piston-rod double-linked cylinder 182 also includes a third piston rod 1821 and a fourth piston rod 1822 arranged along the third direction Z. The third piston rod 1821 is connected to the other side of the first auxiliary probe group 160 along the second direction Y, and the fourth piston rod 1822 is connected to the other side of the second auxiliary probe group 170 along the second direction Y. The movement directions of the third piston rod 1821 and the fourth piston rod 1822 are also opposite, and they work together to ensure that the auxiliary probe group can move smoothly and accurately to the desired position.

[0245] Through this double piston rod double linkage design, the calibration device 100 can efficiently and reliably adjust the position of the auxiliary probe group to adapt to different types and specifications of devices to be calibrated. This structure not only improves the convenience of operation and the accuracy of calibration, but also enhances the stability and durability of the entire system.

[0246] It is understandable that in some embodiments, in order to further optimize the mobility of the auxiliary probe group, a buffer element, such as a spring or a damper, can be added between the piston rod and the probe group to absorb impact and reduce vibration, thereby improving positioning accuracy. In addition, in order to ensure reliability in long-term use, the double-piston rod double-linked cylinder can be made of wear-resistant materials and lubricated regularly to reduce wear. At the same time, considering the various working conditions that may be encountered in actual applications, the drive assembly should also have a certain overload protection function to prevent damage caused by excessive external force. Finally, in order to simplify maintenance work, the design of the drive assembly should be easy to disassemble and inspect to ensure the continuous operation of the equipment.

[0247] In some embodiments, at least one calibration column 120 in the first calibration group a is capable of moving relative to the base 110 along the second direction Y, so that each calibration column 120 in the first calibration group a has at least two relative positions. This design allows the calibration column 120 to adjust its position according to different types of devices to be calibrated, thereby adapting to the calibration requirements of various types of single-phase electricity meters or other similar equipment. Similarly, at least one calibration column 120 in the second calibration group b and the third calibration group c is also capable of moving relative to the base 110 along the second direction Y to provide at least two relative positions for calibrating different types of single-phase electricity meters.

[0248] For the fourth calibration group d and the sixth calibration group f, at least one of the calibration columns 120 can also move relative to the base 110 along the second direction Y, thereby providing at least two relative positions for two acquisition terminals 300 (such as three-phase electric energy meters, special transformer acquisition terminals or concentrators). Through such a structural setting, the calibration device 100 can flexibly adjust the position of the calibration column 120 to ensure accurate and reliable calibration of devices to be calibrated of different sizes and specifications.

[0249] Specifically, when different types of single-phase electric energy meters 200 need to be calibrated, the relative distance between them can be changed by moving the calibration columns 120 in the first calibration group a, the second calibration group b, or the third calibration group c to match the specific size of the device to be calibrated. For example, some single-phase electric energy meters may be wider or taller than other models, so a larger spacing is required to accommodate these devices. By adjusting the position of the calibration column 120, the calibration device 100 can achieve the best contact point, thereby improving the accuracy of the calibration result.

[0250] It is understandable that in some embodiments, in order to further improve the flexibility and accuracy of the position adjustment of the calibration column 120, a micro linear drive or servo motor can be installed on each calibration column 120, and closed-loop control can be achieved in combination with sensor technology. In this way, not only can the displacement of each calibration column 120 be accurately controlled, but also its position can be monitored in real time to ensure that the predetermined position can be reached each time the calibration is performed. In addition, considering the diversity in actual operations, the calibration column 120 can also be equipped with a replaceable probe head so that a suitable contact end can be selected according to different types of devices to be calibrated. Finally, in order to simplify maintenance work and extend service life, the calibration column 120 and its drive components should be made of wear-resistant materials and lubricated regularly to reduce friction losses.

[0251] Reference Figures 1 to 3 In some embodiments, the verification device 100 further includes a fixed bracket and a fifth driving assembly. The base 110 is movably connected to the fixed bracket, and the fifth driving assembly is respectively connected to the fixed bracket and the base 110. The fifth driving assembly is configured to drive the base 110 to move relative to the fixed bracket along the first direction X. This design enables the entire verification device 100 to move as a whole on a horizontal plane, thereby adapting to a larger range of working areas or facilitating switching between different workstations.

[0252] Specifically, when the verification device 100 needs to be moved from one station to another, the fifth driving assembly can be started to push the base 110 to slide along the first direction X. This not only improves the operational flexibility of the verification device 100, but also simplifies the layout adjustment process on the production line. In this way, the verification device 100 can quickly respond to different production needs and improve the overall work efficiency.

[0253] It is understood that, in some embodiments, in order to ensure the stability and reliability of the movement of the base 110, the fixed bracket may include a bottom plate and a first slider and a second slider connected to the bottom plate. The first slider and the second slider are arranged at intervals along the second direction Y, and one side of the base 110 is slidably connected to the first slider, and the other side is slidably connected to the second slider. This dual slider design ensures that the base 110 will not deflect during the movement, while providing sufficient support force.

[0254] In addition, the fifth drive component can use a high-precision linear actuator or servo motor, and combine it with a position sensor to achieve precise control. For example, a photoelectric encoder or other position detection device can be installed between the base 110 and the fixed bracket to feed back the position information of the base 110 to the control system in real time, and achieve precise position adjustment through the PID control algorithm. This not only improves the stability during the movement process, but also ensures the accuracy of each positioning.

[0255] In addition, considering the wear and tear that may occur during long-term use, the surfaces of the slider and the guide rail can be made of self-lubricating materials to reduce friction and extend service life. At the same time, in order to cope with emergencies, the fifth drive component should also have an emergency stop function to ensure that the movement can be stopped immediately in the event of an abnormality to ensure the safety of the operator. Finally, in order to simplify maintenance work, the design of the drive component should be easy to disassemble and inspect to ensure the continuous operation of the equipment.

[0256] Reference Figure 3 In some embodiments, the fixed support includes a bottom plate and a first slider and a second slider connected to the bottom plate. The first slider and the second slider are arranged at intervals along the second direction Y, and one side of the base 110 is slidably connected to the first slider, and the other side is slidably connected to the second slider. This design enables the base 110 to slide smoothly relative to the first slider and the second slider along the first direction X, thereby realizing the movement of the verification device 100 between different positions.

[0257] Specifically, when the position of the calibration device 100 needs to be adjusted, the fifth drive assembly will start and push the base 110 to move along the first direction X. Since the base 110 is connected to the fixed bracket through sliders on both sides, this ensures that the base 110 remains stable and does not shift during the entire movement process. The design of the slider not only provides the necessary support, but also reduces friction, allowing the base 110 to slide smoothly. Such a structural setting allows the calibration device 100 to be quickly and accurately positioned to different working areas according to actual needs, thereby improving the flexibility and efficiency of operation.

[0258] It is understood that in some embodiments, in order to further improve the accuracy and smoothness of the movement of the base 110, a precision guide rail or ball screw system can be used between the slider and the base 110. These high-precision components can significantly reduce vibration and deviation during movement, ensuring that each positioning can reach the expected position. In addition, in order to monitor the position of the base 110 in real time and achieve precise control, a position sensor (such as a photoelectric encoder) can be installed on the base 110, and the data can be fed back to the control system. Through a closed-loop control algorithm, such as PID control, the movement of the base 110 can be finely adjusted to achieve the best working state.

[0259] In addition, considering the wear problem in long-term use, the surface of the slider and the guide rail can be made of self-lubricating material or surface treated to reduce the friction coefficient and extend the service life. At the same time, in order to deal with emergencies, the fifth drive component can also integrate an emergency stop function. Once an abnormal situation is detected, the movement of the base 110 can be stopped immediately to ensure safe operation.

[0260] To simplify maintenance, the design of the slider and rail should be easy to disassemble and replace, so that regular inspection and cleaning can be carried out. In addition, to prevent dust and other impurities from entering the rail system, you can consider adding protective covers or sealing strips at key locations to keep the internal components clean and in good working condition.

[0261] Finally, considering the needs of different application scenarios, the fifth drive component can adopt various types of drive sources, such as electric, pneumatic or hydraulic drive, and select the most suitable drive mode according to the specific working environment and performance requirements. This can not only meet the diverse application needs, but also optimize the performance and reliability of the overall system.

[0262] The following is an explanation of the structure and state switching of the verification device in some embodiments of the present application.

[0263] The following system exemplifies the structure of the calibration device 100 of the present application. The calibration device 100 of the present invention includes a base 110, a calibration column 120, a first drive component 130, a second drive component 140, a third drive component 150, a first auxiliary probe group 160, a second auxiliary probe group 170, a fourth drive component 180 and a fifth drive component.

[0264] Specifically, the base 110 includes a fixed bracket, a bottom plate, a first slider and a second slider. The base 110 serves as a supporting structure of the entire calibration device 100, and the fixed bracket is connected to the ground or other infrastructure through the bottom plate. The first slider and the second slider are arranged at intervals along the second direction Y, and are used to be slidably connected to the calibration column 120 or other components to achieve relative movement.

[0265] The calibration column 120 includes a detection end 121, a drive end 122, a voltage column 123 and a current column 124. The detection end 121 is used to connect to the device to be calibrated (such as an electric energy meter) to detect electric energy parameters.

[0273] In summary, the calibration device 100 of the present invention integrates the first calibration group a, the second calibration group b, the third calibration group c, the fourth calibration group d, the fifth calibration group e, and the sixth calibration group f. Through the host computer software instructions, the RS485 communication mode control realizes the intelligent switching, intelligent avoidance, and time-sharing calibration of the single-phase electric energy meter 200 and the acquisition terminal 300. The implementation method is pneumatic or electric. The following description takes the pneumatic method as an example to systematically explain the calibration device 100 of the present invention.

[0274] 1. The calibration device 100 is provided with three groups of calibration columns 120, which correspond to the connection positions of three single-phase electric energy meters (the first calibration group a, the second calibration group b, and the third calibration group c). Each group of calibration columns 120 is arranged along the second direction Y, and the center distance is fixed. The calibration columns 120 at both ends of the first calibration group a and the third calibration group c are used as the primary positioning reference to determine the connection positions of the three single-phase electric energy meters. On this basis, according to the size of the terminal and auxiliary terminal of the three-phase electric energy meter, the connection positions of the two three-phase electric energy meters (the fourth calibration group d and the sixth calibration group f) are secondary positioned. Specifically, a total of three single-phase electric energy meters (single-phase electric energy meters 200) are set up at the connection positions of A, B, and C. These three connection positions correspond to the first calibration group a, the second calibration group b, and the third calibration group c, respectively. Each calibration group is provided with four calibration columns 120, and the calibration columns 120 corresponding to the connection positions of A, B, and C are: A1, A2, A3, A4; B1, B2, B3, B4; C1, C2, C3, C4. The center distances between the connection positions of the three single-phase electric energy meters A, B, and C are all between 128mm and 134mm, for example, 128mm, 129mm, 130mm, 131mm, 132mm, 133mm, and 134mm, and the optimal value is 131mm. The three single-phase electric energy meters 200 are positioned using the A1 calibration column 120 and the C4 calibration column 120 as the primary positioning reference. Based on the primary positioning reference, the auxiliary terminal of the three-phase electric energy meter (collection terminal 300) and the size limit of the verification column 120 are used as the secondary positioning reference to locate the D and E connection positions of the three-phase electric energy meter (collection terminal 300), and set the connection positions of the two three-phase electric energy meters. When the two three-phase electric energy meters are three-phase mutual inductance access type, refer to Fig.13, from left to right, the connection positions of the two three-phase electric energy meters correspond to calibration column D1, calibration column D2, calibration column D3, calibration column D4, calibration column D5, calibration column D6, calibration column D7, calibration column D8, calibration column D9, calibration column D10, calibration column E1, calibration column E2, calibration column E3, calibration column E4, calibration column E5, calibration column E6, calibration column E7, calibration column E8, calibration column E9, calibration column E10; when the two three-phase electric energy meters are three-phase direct access electric energy meters, refer to Fig.15 The connection positions of the two three-phase electric energy meters correspond to calibration column D11, calibration column D12, calibration column D13, calibration column D14, calibration column D15, calibration column D16, calibration column D17, calibration column E11, calibration column E12, calibration column E13, calibration column E14, calibration column E15, calibration column E16, calibration column E17 respectively.

When calibrating a three-phase direct-access watt-hour meter, it can be connected to terminal D16; when calibrating a three-phase direct-access watt-hour meter, the calibration terminal D17 (B1) can be connected to terminal D17, and when calibrating a single-phase watt-hour meter, it can be connected to terminal B1; when calibrating a three-phase transformer-access watt-hour meter, the calibration terminal E1 (E11, B4) can be connected to terminal E1, and when calibrating a three-phase direct-access watt-hour meter, it can be connected to terminal E11, and when calibrating a single-phase watt-hour meter, it can be connected to terminal B4; when calibrating a three-phase transformer-access watt-hour meter, the calibration terminal E3 (E12) can be connected to terminal E3, and when calibrating a three-phase direct-access watt-hour meter, it can be connected to terminal E12; when calibrating a three-phase transformer-access watt-hour meter, the calibration terminal E4 (E13) can be connected to the terminal E4 when calibrating the three-phase transformer-connected watt-hour meter, and can be connected to the terminal E13 when calibrating the three-phase direct-connected watt-hour meter; the calibration terminal E6 (E14, C1) can be connected to the terminal E6 when calibrating the three-phase transformer-connected watt-hour meter, can be connected to the terminal E14 when calibrating the three-phase direct-connected watt-hour meter, and can be connected to the terminal C1 when calibrating the single-phase watt-hour meter; the calibration terminal E7 (E15, C2) can be connected to the terminal E7 when calibrating the three-phase transformer-connected watt-hour meter, can be connected to the terminal E15 when calibrating the three-phase direct-connected watt-hour meter, and can be connected to the terminal C2 when calibrating the single-phase watt-hour meter;The calibration column E9 (E16, C3) can be connected to the terminal E9 when calibrating the three-phase transformer-connected energy meter, can be connected to the terminal E16 when calibrating the three-phase direct-connected energy meter, and can be connected to the terminal C3 when calibrating the single-phase energy meter; the calibration column E17 (C4) can be connected to the terminal E17 when calibrating the three-phase direct-connected energy meter, and can be connected to the terminal C4 when calibrating the single-phase energy meter. Thus, the present application is compatible with single-phase energy meters, three-phase transformer-connected energy meters, and three-phase transformer-connected energy meters. Among them, B1 and B4 are configured to be movable so as to form a group with other calibration columns 120 to calibrate different equipment. ;

[0276] 2. According to the difference in terminal spacing between single-phase electric energy meters, three-phase electric energy meters connected via transformers, and three-phase electric energy meters directly connected, the spacing dimensions between the calibration columns 120 are set to ensure that different types of electric energy meters can be correctly connected. Below, the connection positions of the electric energy meters are sorted in the order of 1, 2, 3, and 4 for ease of description. Specifically, according to the terminal spacing deviation values ​​of the single-phase electric energy meter (single-phase electric energy meter 200), the three-phase electric energy meter connected via transformers (collection terminal 300), and the three-phase electric energy meter directly connected (collection terminal 300), the spacing dimensions of the calibration columns 120 corresponding to the connection positions are set: the spacing of the calibration columns 120 corresponding to the connection positions 1-4 of each single-phase electric energy meter is between 17mm and 23mm, for example, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, the optimal value is 20mm (the difference of 0.5mm from the distance between the two terminals of the electric energy meter is 21mm, which does not affect the connection); the distance between the calibration columns 120 of the three-phase transformer-connected electric energy meter connection positions 1 and 3, 4 and 6, 7 and 9 is 20mm; the distance between the calibration columns 120 of the direct-connected connection positions 11-12, 13-14, 15-16 is between 17mm and 23mm, such as 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, and the optimal value is 20mm;

[0277] 3. The grouping and configuration of the calibration posts 120 are based on the terminal layout of the three-phase electric energy meter. Each group of calibration posts 120 corresponds to a specific terminal combination to meet the calibration requirements of different types of electric energy meters. At the same time, movable positioning blocks (realized by the reconfiguration of the calibration posts 120), such as B1 and B4, are set between the calibration positions of the single-phase electric energy meter. These positioning blocks can be intelligently avoided when calibrating the three-phase electric energy meter without affecting the calibration process. Specifically, Fig.12As shown, the three-phase transformer-connected watt-hour meter terminals are grouped as follows: D1-D3 is group 1, D4-D6 is group 2, D7-D9 is group 3, D10 plus three-phase direct-connected watt-hour meter terminal D17 is group 4, E1-E3 is group 5, E4-E6 is group 6, E7-E9 is group 7, E10 plus three-phase direct-connected watt-hour meter terminal E17 is group 8, and positioning blocks B2 and B3 are group 9.

[0278] 4. In the calibration position of the single-phase electric energy meter (the second calibration group b), movable positioning columns (realized by the movement of the calibration column 120) are set. These positioning columns can intelligently avoid when calibrating the three-phase electric energy meter and keep their positions unchanged through the support structure fixedly installed on the base 110. Fig.12 , for example, B1 and B4 are configured to be movable. The setting of the positioning column realizes the intelligent switching and variable pitch adjustment between the calibration columns 120 to adapt to the calibration requirements of electric energy meters of different sizes. The left and right variable pitch dimensions are less than a specific value (such as 22mm), and the front and rear movement dimensions are also less than another specific value (such as 35mm) to meet the calibration requirements of different electric energy meters. Specifically, there are positioning blocks (limit blocks) and terminal posts in the single-phase electric energy meter connection position setting (the middle blank position of the two three-phase electric energy meter connection positions), for example Fig.12 For B1 and B4 in the figure, the positioning block height is set to 32.6mm (up and down range 5mm), and the length is set to 47.5mm (left and right range 5mm). The positioning block is provided with a terminal and a through hole to facilitate installation and intelligent avoidance. The positioning block is fixedly installed on the meter support plate. When avoiding the through hole, the positioning block remains fixed. The positioning block setting realizes the intelligent switching of the variable pitch plate: the left and right variable pitch size is less than 30mm, which is implemented as 22mm in this application; the front and rear movement size is less than 40mm, which is implemented as a total of 35mm for the first and second variable pitch front and rear movements in this application;

[0279] 5. According to the design of the verification device 100, specifically, Fig.12 and Fig. 20 As shown in the figure, based on the terminal set by the deviation value, the three-phase direct access type energy meter connection position: D11-D17 corresponds to the three-phase transformer access type energy meter D1-D10; the three-phase direct access type energy meter connection position: E11-E17 corresponds to the three-phase transformer access type energy meter E1-E10. In this way, the connection terminal of the three-phase transformer access type energy meter and the connection terminal of the three-phase direct access type energy meter are reused to achieve compatible time-sharing verification requirements.

[0280] 6. For the calibration position setting of single-phase electric energy meter, the previous article has passed Fig.12 The functions of each inspection column 120 are given as examples and will not be described in detail here.

[0281] 7. The initial state of the auxiliary probe assembly of the calibration device 100 is set to the three-phase smart meter calibration state, that is, the second auxiliary probe group 170 is in the front position, and the first auxiliary probe group 160 is in the rear position (active avoidance state). Specifically, the initial position of the meter socket auxiliary probe assembly is the three-phase smart meter connected to the meter socket state (the front position of the three-phase auxiliary probe assembly and the rear position of the single-phase auxiliary probe assembly), and the single-phase auxiliary probe assembly is in the active avoidance state.

[0282] 8. In the initial state, when the three-phase IoT meter is calibrated, the control board and the solenoid valve drive the corresponding drive components (such as the first drive component 130) through the host computer instructions and RS485 communication, so that the first auxiliary probe group 160 maintains an active avoidance state, and the second auxiliary probe group 170 retreats to the rear position through the reaction force during docking for passive avoidance. After the calibration is completed, the initial state is restored. Specifically, Fig.10 As shown, in the initial state, when the three-phase IoT meter is calibrated, the host computer command is used to communicate via RS485, and the control board and the solenoid valve drive the double-piston non-linked cylinder (alternating action cylinder) to perform the deflation action (no resistance state). The single-phase auxiliary probe assembly is initially in an active avoidance state, and the three-phase auxiliary probe assembly retreats to the rear end position for passive avoidance through the reaction force of the three-phase IoT meter connection when connected. After the calibration is completed, the initial position state is restored.

[0283] 9. In the initial state, when the single-phase smart energy meter is calibrated, RS485 communication is adopted through the host computer instruction, and the control board and the solenoid valve drive the corresponding drive components to switch, so that the first auxiliary probe group 160 extends to the front position, and the second auxiliary probe group 170 retreats to the rear position for active avoidance. After the calibration is completed, the initial state is restored. Specifically, in the initial state, when the single-phase smart energy meter is calibrated, RS485 communication is adopted through the host computer instruction, and the control board and the solenoid valve drive the double-piston non-linked cylinder (alternating action cylinder) to perform switching, and the single-phase auxiliary probe assembly extends (front position) and the three-phase auxiliary probe assembly retreats (rear position) in an active avoidance state. After the calibration is completed, the initial position state is restored.

[0284] 10. In the initial state, when the single-phase IoT meter is calibrated, the control board and the solenoid valve drive the corresponding drive components to switch to the single-phase smart meter calibration state through the host computer instruction and RS485 communication, and then perform the deflation action to keep the second auxiliary probe group 170 in the active avoidance state. When docking, the first auxiliary probe group 160 retreats to the rear end position through the reaction force for passive avoidance. After the calibration is completed, the initial state is restored. Specifically, in the initial state, when calibrating the single-phase IoT meter, the host computer instructions are used to communicate via RS485, and the control board and solenoid valve drive the double-piston non-linked cylinder (alternating action cylinder) to switch to the single-phase smart meter state, the single-phase auxiliary probe assembly extends (front end position), and the three-phase auxiliary probe assembly retreats (rear end position), and then the double-piston non-linked cylinder deflation action is executed (no resistance state), and the rear end position of the three-phase auxiliary probe assembly is in an active avoidance state, and the single-phase auxiliary probe assembly retreats to the rear end position for passive avoidance through the reaction force of the single-phase IoT meter connection when connected. After the calibration is completed, the initial position is restored.

[0285] 11. In the default state of the calibration device 100, all calibration columns 120 and auxiliary probe groups are in the initial position. After receiving the control command, the device 100 automatically switches to multiple modes such as calibrating single-phase devices to be calibrated, calibrating three-phase devices to be calibrated (including transformer access or direct access), etc. The operation is as follows:

[0286] (1) Three-phase transformer-connected device to be tested: In the initial state, upon receiving the control instruction (supporting local manual control) of the "three-phase transformer-connected device to be tested" test task, the test device 100 automatically controls part of the test column 120 to move, so that the fourth test group d and the sixth test group f are formed. Fig.12 and Fig.13 The corresponding calibration column 120 (such as D17, E17, etc.) shown in the figure avoids to the non-calibration position, the three-phase auxiliary probe assembly (the second auxiliary probe group 170) is in the initial position (front end position), and the single-phase auxiliary probe assembly (the first auxiliary probe group 160) moves to the non-calibration position to avoid, so as to realize the calibration column 120 of the 2-position three-phase mutual inductor access device to be calibrated, and the calibration device 100 of the auxiliary probe calibration requirements can be adjusted autonomously, and the docking and system calibration are completed in coordination with the docking cylinder (drive component). After completing the calibration and exiting the docking, the calibration device 100 returns to the initial position.

[0287] (2) Three-phase direct access device to be tested: In the initial state, upon receiving the control instruction (supporting local manual control) "three-phase direct access device to be tested" test task, the test device 100 automatically controls the variable pitch component (such as through the first drive component 130, etc.) to adjust the relative position of the test column 120 to the middle position, and controls part of the test column 120 to move to the non-test position to avoid, while the three-phase auxiliary probe component (the second auxiliary probe group 170) is in the initial position (front end position), and the single-phase auxiliary probe component (the first auxiliary probe group 160) moves to the non-test position to avoid, so as to realize the autonomous adjustment of the test column 120 and the auxiliary probe test requirements of the two-position three-phase direct access device to be tested, and cooperate with the corresponding drive component action to complete the docking and system test. After completing the test and exiting the docking, the test device 100 returns to the initial position. The adjustment of the variable pitch component can be achieved by controlling the test column 120 to move different distances along the second direction Y by the drive component according to the specific test requirements.

[0288] Specifically, regarding the three-phase direct access smart energy meter, in the initial state, it receives the host computer instruction (supports local manual control) "three-phase direct access smart energy meter" connection task, Fig.13 , Fig.14 as well as Fig.16 The meter socket shown in the figure automatically controls the pitch change component to change the pitch to the middle position and pull the terminal component backward. D2, D5, D8, D10, E2, E5, E8, and E10 actively avoid the rear position. The initial position (front position) of the three-phase auxiliary probe component and the rear position of the single-phase auxiliary probe component actively avoid the meter socket to realize the autonomous deformation of the two-position three-phase direct-access smart energy meter terminal and auxiliary probe verification requirements, and cooperate with the connection cylinder to complete the connection and system verification. After the verification is completed and the connection is exited, the meter socket returns to the initial position.

[0289] Specifically, refer to Fig.12 , grouped by three-phase transformer-connected watt-hour meter terminals: D1-D3 is group 1, D4-D6 is group 2, D7-D9 is group 3, D10 plus three-phase direct-connected watt-hour meter terminal D17 is group 4, E1-E3 is group 5, E4-E6 is group 6, E7-E9 is group 7, and E10 plus three-phase direct-connected watt-hour meter terminal E17 is group 8. Fig.21 and Fig. 22, the first pitch change: the cylindrical sliders of the 1st and 5th groups of modules move right by 2mm under the limit of the 1st and 5th chutes of the pitch change plate (the angle θ between the first pitch change section of the 1st and 5th chutes of the pitch change plate and the horizontal line is ≥78°, and the value is 78.69° in this embodiment), and the cylindrical sliders of the 2nd and 6th groups of modules move right by 3.5mm under the limit of the 2nd and 6th chutes of the pitch change plate (the angle θ between the first pitch change section of the 2nd and 6th chutes of the pitch change plate and the horizontal line is ≥70°, and the value is 70.7 in this embodiment). 1°), the 3rd and 7th module cylindrical sliders move 5mm to the right under the limit of the 3rd and 7th slide grooves of the variable pitch plate (the angle θ between the first pitch changing section of the 3rd and 7th slide grooves of the variable pitch plate and the horizontal line is ≤70°, and the value is 63.43° in this embodiment), and the 4th and 8th module cylindrical sliders move 1mm to the right under the limit of the 4th and 8th slide grooves of the variable pitch plate (the angle between the first pitch changing section of the 4th and 8th slide grooves of the variable pitch plate and the horizontal line is greater than or equal to 84°, and the value is 84.29° in this embodiment).

[0290] (3) Three-phase transformer-connected IoT device to be tested: In the initial state, upon receiving the control instruction (supporting local manual control) of the test task of "three-phase transformer-connected IoT device to be tested", the test device 100 automatically controls part of the test column 120 to move to form the fourth test group d and the sixth test group f, while the auxiliary probe group is in a resistance-free state under the control of the driving component. Fig.13 The corresponding calibration column 120 (such as D17, E17, etc.) is moved to a non-calibration position. Fig. 9 The single-phase auxiliary probe assembly (first auxiliary probe group 160) shown moves to the non-calibration position to avoid, and the three-phase auxiliary probe assembly (second auxiliary probe group 170) (initial position) retreats to the non-calibration position to complete passive avoidance through the reaction force of the device to be calibrated during docking, realizing the autonomous adjustment of the calibration column 120 of the 2-position three-phase mutual inductor-connected IoT device to be calibrated and the calibration device 100 for the auxiliary probe calibration requirements, and cooperates with the corresponding drive component action to complete the docking and system calibration. After completing the calibration and exiting the docking, the calibration device 100 returns to the initial position.

[0291] Specifically, in the initial state, after receiving the host computer command (supporting local manual control) of the "three-phase mutual inductor connected IoT meter" connection task, the meter socket automatically controls the three actions of the rear-pull terminal assembly, and the auxiliary probe moving assembly one and two are synchronously deflated (double-piston non-linked cylinder has no resistance state). Fig.13 As shown, D17 and E17 avoid to the rear position actively, the rear position of the single-phase auxiliary probe assembly actively avoids, and the three-phase auxiliary probe assembly (front position) retreats to the rear position to complete passive avoidance through the reaction force of the IoT meter connection when the connection cylinder is actuated, realizing the autonomous deformation of the connection socket for the 2-position three-phase IoT meter terminal connected via a mutual inductor and the auxiliary probe calibration requirements, and completing the connection and system calibration in coordination with the connection cylinder action. After the calibration is completed and the connection is exited, the connection socket returns to the initial position.

[0292] (4) Three-phase direct access IoT device to be tested: In the initial state, upon receiving the control instruction (supporting local manual control) of the "three-phase direct access IoT device to be tested" test task, the test device 100 automatically controls the variable pitch component to adjust the relative position of the test column 120 to the middle position, and controls part of the test column 120 to move to the non-test position to avoid the test. At the same time, the auxiliary probe group is in a resistance-free state under the control of the drive component. Fig. 9 The single-phase auxiliary probe assembly (first auxiliary probe group 160) shown moves to the non-calibration position to avoid, and the three-phase auxiliary probe group (second auxiliary probe group 170) (initial position) retreats to the non-calibration position to complete passive avoidance through the reaction force of the device to be verified during docking, so as to realize the autonomous adjustment of the calibration column 120 and the auxiliary probe calibration requirements of the 2-position three-phase direct access IoT device to be verified, and the docking and system calibration are completed in coordination with the corresponding drive component actions. After completing the calibration and exiting the docking, the calibration device 100 returns to the initial position.

[0293] Specifically, in the initial state, after receiving the host computer command (supporting local manual control) "three-phase direct access to the Internet of Things meter" connection task, the meter socket automatically controls the pitch change component to change the pitch to the middle position, pulls the terminal component back, and the auxiliary probe moving components one and two are deflated synchronously (double piston non-linked cylinder has no resistance), D2, D5, D8, D10, E2, E5, E8, E10 actively avoid to the rear position, the single-phase auxiliary probe component actively avoids to the rear position, and the three-phase auxiliary probe component (front position) retreats to the rear position through the reaction force of the Internet of Things meter connection when the connection cylinder is actuated to complete passive avoidance, so as to realize the autonomous deformation of the meter socket for the verification requirements of the two-position three-phase direct access to the Internet of Things meter terminal and auxiliary probe, and completes the connection and system verification in cooperation with the connection cylinder. After the verification is completed and the connection is exited, the meter socket returns to the initial position.

[0294] (5) Single-phase device to be tested: In the initial state, upon receiving the control command (local manual control is supported) of the "single-phase device to be tested" test task, the test device 100 automatically controls the variable pitch component to adjust the relative position of the test column 120 to the middle position, and further adjusts it to the farthest position, while controlling part of the test column 120 to move to the non-test position to avoid the test.

At the same time, the auxiliary probe group is in a resistance-free state under the control of the drive component, and controls part of the test column 120 to move to the non-test position to avoid, the three-phase auxiliary probe group moves to the non-test position to avoid, and the single-phase auxiliary probe group (initial position) retreats to the non-test position to complete passive avoidance through the reaction force of the device to be tested during docking, realizing the autonomous adjustment of the test column 120 and auxiliary probe test requirements of the three-position single-phase IoT device to be tested, and cooperates with the corresponding drive component action to complete the docking and system test. After completing the test and exiting the docking, the test device 100 returns to its initial position.

After completing the verification and exiting the connection, the meter socket returns to the initial position.

[0298] It should be noted that if there are directional indications (such as up, down, left, right, front, back, etc.) involved in the embodiments of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. When a directional reference is introduced in a specific embodiment, if the direction is not specifically limited to single-phase, the direction can be single-phase or bidirectional (two parallel and opposite directions). Whether it is single-phase or bidirectional is based on what can be achieved by ordinary technicians in this field. When the directional reference is bidirectional, it should be considered that two different parallel embodiments are introduced at the same time.

[0299] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
