Description

Technical Field

[0001] The present invention belongs to the technical field of electric energy meter verification, and particularly relates to a verification system capable of adapting to electric energy meters of multiple specifications. Background Art

[0002] At present, intelligent electric energy meters with an integrated design are widely used. However, when such electric energy meters malfunction, the only feasible way to ensure the smooth progress of power metering work is to replace the electric energy meters. Moreover, to prevent inaccurate power metering caused by the tampering of the electric energy meter program, the software of the electric energy meter does not allow online upgrading. The intelligent electric energy meters with an integrated design not only have a short service life, but also when new requirements are put forward for the functions of the electric energy meters, the replacement of a large number of electric energy meters will inevitably cause waste of resources and reduction of social benefits.

[0003] In 2012, the "Technical Committee on Electrical Measuring Instruments" of the International Organization of Legal Metrology formulated the IR46 active energy meter standard, which broke through the integrated design concept, requiring the separation of the electronic equipment and components of the electric energy meter, the independence of the metering function and other functions, and the online upgrading of the non-metering part not affecting the accuracy and stability of the metering part. It can be foreseen that the intelligent electric energy meters meeting the IR46 standard will be widely used in the future.

[0004] However, it takes time to change from the intelligent electric energy meters with an integrated design to the intelligent electric energy meters meeting the IR46 standard, and there are also various models of the currently used integrated intelligent electric energy meters. During this period, the verification equipment for electric energy meters needs to be able to meet the verification requirements of various models of integrated intelligent electric energy meters and intelligent electric energy meters meeting the IR46 standard at the same time.

[0039] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not require further discussion in subsequent drawings.

[0040] In the description of the present application, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description.

[0043] Please refer to Figures 1 to 6 for an explanation of the verification system provided by the present invention that can adapt to various specifications of electricity meters.

[0044] The verification system that can adapt to various specifications of electricity meters includes a conveyor belt 10, a model identification component 20, and a verification component 30; the conveyor belt 10 is used to transport electricity meters; the model identification component 20 is arranged on one side of the conveyor belt 10 and is used to identify the model of the electricity meter; the verification component 30 includes a base 311, a verification terminal, a wiring component, and a pulse detection component. The wiring component and the pulse detection component are both connected to the base 311. The wiring component is connected to the electricity meter and is used to obtain the measurement data of the electricity meter. The pulse detection component is used to obtain the measurement data output by the electricity meter in the form of pulse signals. The verification terminal is connected to the wiring component and the pulse detection component and is used to receive the measurement data obtained by the wiring component and the pulse detection component; the wiring component includes a probe component and a spacing adjustment component. The probe component elastically has a plurality of probes, and the spacing adjustment component is used to adjust the spacing between the plurality of probes so that the probe component can be connected to electricity meters of different models; the verification terminal is a computer.

[0045] The beneficial effects of the calibration system provided in this embodiment that can adapt to various specifications of electric energy meters are as follows: Compared with the prior art, the calibration system provided in this embodiment is provided with a model recognition component 20, which can recognize the model of the electric energy meter to be detected. When the detected electric energy meter is one of the integrated electric energy meters, the control spacing adjustment component is controlled to adjust the spacing between the probes on the probe component so that it matches the electric energy meter to be detected. Then, the probes in the probe component are respectively connected to the current and voltage terminals and the auxiliary communication terminals of the electric energy meter, providing current and voltage for the electric energy meter, obtaining the measurement data of the electric energy meter, and transmitting the measurement data to the calibration terminal; when the detected electric energy meter is an IR46 electric energy meter, since the intelligent electric energy meter of the IR46 standard does not have an auxiliary communication terminal, the control spacing adjustment component is controlled to adjust the spacing between several probes on the probe component so that it matches the electric energy meter to be detected. The probes connected to the current and voltage terminals of the electric energy meter are connected to the current and voltage terminals of the IR46 electric energy meter to provide current and voltage for it. The probes connected to the auxiliary communication terminals retract under the extrusion of the electric energy meter. Through the pulse detection component, the measurement data output in the form of pulse signals of the electric energy meter to be detected is obtained, and the measurement data is transmitted to the calibration terminal. That is, the calibration system provided by the present invention can simultaneously meet the calibration requirements of intelligent electric energy meters with integrated designs of various models and IR46 standard electric energy meters.

[0046] As shown in the figure, in a specific implementation manner, a tray 11 is provided on the conveyor belt 10. A number of storage slots are provided in the tray 11, and the storage slots are used to place electric energy meters. The electric energy meters in the tray 11 are of the same specification.

[0047] Specifically, six storage slots are provided in the tray 11, which can store six electric energy meters of the same specification, and the connection terminals of the six electric energy meters all face both sides of the conveyor belt 10.

[0048] Such as Figure 1 shown, in a specific implementation manner, an information code for recording the model of the electric energy meter in the tray 11 is provided on one side of the tray 11. The model recognition component 20 includes a barcode scanner, and the barcode scanner is provided at the loading end of the conveyor belt 10 to recognize the information in the information code on the tray 11 to identify the model of the electric energy meter to be detected.

[0049] Such as Figure 2 and Figure 3As shown, in a specific embodiment, there are two sets of guiding mechanisms provided on the base 311, which are horizontally arranged and parallel to each other in the vertical plane. Each guiding mechanism includes at least two sliding rods 312 that are parallel to each other in the horizontal plane. The probe includes a main probe 321 mechanism and an auxiliary probe 323 mechanism. The main probe 321 mechanism is slidably connected to the lower sliding rod 312, and the auxiliary probe 323 mechanism is slidably connected to the upper sliding rod 312. The main probe 321 mechanism is used to connect to the current and voltage terminals of the electricity meter, and the auxiliary probe 323 mechanism is used to connect to the auxiliary communication terminals of the electricity meter.

[0050] As Figures 2 to 4 shown, in a specific embodiment, the main probe 321 mechanism includes a number of main probes 321, a number of main connection seats 322, and a number of first springs. Each of the main connection seats 322 is provided with a first accommodation cavity. The main probes 321 are respectively slidably arranged in the first accommodation cavities of the main connection seats 322, and one end extends out of the main connection seat 322 for connecting to the electricity meter. The first springs are respectively arranged in the first accommodation cavities of the main connection seats 322 and are clamped between the main probes 321 and the main connection seats 322. The auxiliary probe 323 mechanism includes a number of auxiliary probes 323, a number of auxiliary connection seats 324, and a number of second springs. Each of the auxiliary connection seats 324 is provided with a second accommodation cavity. The auxiliary probes 323 are respectively slidably arranged in the second accommodation cavities of the auxiliary connection seats 324, and one end extends out of the auxiliary connection seat 324 for connecting to the electricity meter. The second springs are respectively arranged in the second accommodation cavities of the auxiliary connection seats 324 and are clamped between the auxiliary probes 323 and the auxiliary connection seats 324.

[0051] Specifically, the calibration device further includes a standard meter and an error calculator. The calibration terminal, the standard meter, the auxiliary probe 323, and the pulse acquisition module 342 are electrically connected to the error calculator. The error calculator is used to respectively obtain the measurement data of the standard meter and the measurement data of the electricity meter to be calibrated, calculate the measurement error, and transmit the calculation result to the calibration terminal.

[0052] It should be noted that the first spring and the second spring are both in a compressed state, and the main probe 321 and the auxiliary probe 323 are both electrically connected to the calibration terminal. When the number of current and voltage connection terminals on the electricity meter to be detected is less than the number of main probes 321, the redundant main probes 321 will retract into the first accommodation cavity under the extrusion of the electricity meter. When calibrating the IR46 electricity meter, since the IR46 standard smart electricity meter does not have auxiliary communication terminals, the auxiliary probe 323 will retract into the second accommodation cavity under the extrusion of the electricity meter.

[0053] As Figures 2 to 4As shown, in a specific embodiment, the spacing adjustment assembly includes a plurality of spacing adjustment mechanisms and a centering mechanism. The plurality of spacing adjustment mechanisms are respectively arranged between two adjacent main terminal blocks 322 and between two adjacent auxiliary terminal blocks 324. The spacing adjustment mechanism includes an airbag 331, a pressure regulating valve 332, and an adjusting spring 333. Both the airbag 331 and the adjusting spring 333 are sleeved on the sliding rod 312 and are respectively connected to two adjacent main terminal blocks 322 or two adjacent auxiliary terminal blocks 324 at both ends. The pressure regulating valve 332 is communicated with the airbag 331 to adjust the pressure in the airbag 331. The airbag 331 is inflated through an air source; the centering mechanism includes four centering springs 334. The four centering springs 334 are respectively sleeved on the sliding rod 312 and are respectively arranged between the two outermost main terminal blocks 322 and the base 311 and between the two outermost auxiliary terminal blocks 324 and the base 311.

[0054] It should be noted that the adjusting spring 333 is always in a stretched state, the centering spring 334 is always in a compressed state, the airbag 331 does not have elasticity, and the contact areas of both ends of the airbag 331 with the main terminal block 322 and the auxiliary terminal block 324 remain constant; then each determined pressure value in the airbag 331 corresponds one-to-one to the elongation of the adjusting spring 333, that is, corresponds one-to-one to the spacing between two adjacent main probes 321 or the spacing between two adjacent auxiliary probes 323. By adjusting the pressure in the airbag 331 through the pressure regulating valve 332, the spacing between two adjacent main probes 321 or the spacing between two adjacent auxiliary probes 323 can be adjusted, and the pressure regulating valves 332 are all electric control valves to facilitate automation.

[0055] As Figure 2 and Figure 3 As shown, in a specific embodiment, the pulse detection assembly includes a support frame 341 and a pulse acquisition module 342. The support frame 341 is connected to the base 311, and the pulse acquisition module 342 is connected to the support frame 341 to obtain the measurement data output by the meter under test in the form of pulse signals.

[0056] Specifically, the pulse acquisition module 342 can be a wireless acquisition module for the communication module built in the IR46 standard meter. For example, it can be an optical acquisition device or a data receiving module based on wireless communication protocols such as Bluetooth, Zigbee, and WIFI. The type of the pulse acquisition module 342 can be adjusted according to the type of the communication module built in the IR46 standard meter.

[0057] For example, the pulse acquisition module 342 includes an optoelectronic collector, which is configured to form an electrical signal according to the optical signal emitted by the electricity meter to be tested and transmit it to the error calculator. Currently, the pulse signal of the electricity meter conforming to the IR46 standard is emitted as an optical pulse signal. The optoelectronic collector captures the optical pulse signal, converts it into an electrical signal, and outputs it to the error calculator to realize the verification of the error of the IR46 standard electricity meter that transmits data with optical pulse signals.

[0058] For example, the pulse acquisition module 342 includes a Bluetooth pulse acquisition component. The Bluetooth pulse acquisition component includes a Bluetooth receiver and a Bluetooth converter. The Bluetooth receiver is configured to receive the Bluetooth pulse signal broadcast by the electricity meter to be tested, and the Bluetooth converter is configured to convert the Bluetooth pulse signal into an electrical signal that can be recognized by the error calculator. For the IR46 standard electricity meter with a built-in Bluetooth module, the Bluetooth pulse signal can be first received by the Bluetooth receiver, and the Bluetooth pulse signal can be converted into an electrical signal acceptable to the error calculator by the Bluetooth converter, so as to realize the verification of the error of the IR46 standard electricity meter that transmits data with Bluetooth pulse signals.

[0059] It should be noted that the optoelectronic collector, the Bluetooth pulse acquisition component, or other wireless communication components can exist alone or coexist to meet the error verification requirements of the IR46 standard electricity meters with different communication forms. When multiple wireless communication components coexist, a relay for switching communication modes is set, and different types of communication modes are manually selected.

[0060] As Figure 1 shown, in a specific embodiment, a plurality of verification components 30 are provided on both sides of the conveyor belt 10.

[0061] Specifically, the plurality of verification components 30 are six and are evenly arranged on both sides of the conveyor belt 10.

[0062] As Figure 1 shown, in a specific embodiment, a labeling mechanism is further included. The labeling mechanism is arranged on one side of the conveyor belt 10 and is located downstream of the verification component 30.

[0063] As Figures 1 to 6As shown, in a specific embodiment, the labeling mechanism includes a mechanical gripper, a marking machine mechanism, a pushing component, and a stopping mechanism; the mechanical gripper includes clamping plates, a first driving component, a second driving component, and an air pump 470. The clamping plates include a longitudinal plate 411 and a transverse plate 412. The longitudinal plate 411 is used to abut against the side of the electricity meter. One end of the transverse plate 412 is connected to the longitudinal plate 411. A cavity is provided inside the longitudinal plate 411. A plurality of air holes 413 are provided on the side of the longitudinal plate 411 facing the electricity meter. The plurality of air holes 413 communicate with the cavity. The air pump 470 communicates with the cavity. The first driving component includes a driving plate 421, a cross beam 422, and a rotary cylinder 423. The driving plate 421 is arranged below the transverse plate 412 and is provided with an elliptical chute 424. One end of the transverse plate 412 away from the longitudinal plate 411 is provided with a slider 414. The slider 414 is embedded in the chute 424. The cross beam 422 is arranged above the transverse plate 412 and is slidably connected to the transverse plate 412. The rotary cylinder 423 is connected to the cross beam 422. The power output end of the rotary cylinder 423 is connected to the driving plate 421 and is adapted to drive the driving plate 421 to rotate. The second driving component includes a lifting cylinder 431 and a frame 432. The frame 432 is arranged on one side of the conveying mechanism. The lifting cylinder 431 is connected to the frame 432. The power output end of the lifting cylinder 431 is connected to the rotary cylinder 423 to drive the rotary cylinder 423 to move up and down. The marking machine mechanism includes a mounting frame 441, a marking machine 442, a master tape 443, and a collecting component. The marking machine 442 and the collecting component are both connected to the mounting frame 441. The master tape 443 is loaded in the marking machine 442, and a plurality of labels are evenly provided on the master tape 443. The marking machine 442 is used to print the corresponding information of the electricity meter on the labels. The collecting component includes a roller 444 and a third driving component 445. The third driving component 445 is connected to the mounting frame 441. The master tape 443 is wound around the roller 444. The power output end of the third driving component 445 is connected to the roller 444 to drive the roller 444 to rotate. The pushing component is arranged between the marking machine 442 and the collecting component and is used to push the master tape 443 with labels between the two clamping plates so that the labels are respectively aligned with the two clamping plates. The pushing component includes a pushing cylinder 451 and a pushing block 452. The pushing cylinder 451 is arranged horizontally and is connected to the mounting frame 441.

[0064] It should be noted that the air pump 470 can not only blow air into the cavity to generate positive pressure in the cavity, but also extract air to generate negative pressure in the cavity; when the label needs to be adsorbed to the clamping plate, the air pump 470 extracts air, and adsorbs the label to the clamping plate through negative pressure; the two clamping plates are respectively abutted against both sides of the electric energy meter. When pasting the label on the electric energy meter, the air pump 470 blows air, so that the label adheres to the electric energy meter. At the same time, through the positive pressure gas, a certain pressure is applied to the label to make the label adhere more firmly; the third driving assembly 445 is a motor assembly for driving the roller 444 to rotate.

[0065] The working process of the labeling mechanism is as follows: The labeling machine 442 prints the corresponding information on the label in advance. The pushing cylinder 451 drives the pushing block 452 to push the master tape 443 with the label between the two clamping plates, so that the two labels are respectively aligned with the two clamping plates; then the rotating cylinder 423 drives the driving plate 421 to rotate 90°, so that the two clamping plates clamp the pushing plate; at the same time, the air pump 470 starts to extract air, and adsorbs the label to the clamping plate through negative pressure; then, the rotating cylinder 423 drives the driving plate 421 to rotate 90° again, so that the two clamping plates loosen the pushing block 452, the pushing cylinder 451 drives the pushing block 452 to retract, and the third driving assembly 445 drives the roller 444 to rotate to recycle the blank master tape 443; the stopping cylinder 461 drives the stopping rod 462 to extend, and stops the tray 11 carrying the electric energy meter under the two clamping plates. The lifting cylinder 431 drives the rotating cylinder 423 and the two clamping plates to descend, so that the two clamping plates are respectively aligned with both sides of the electric energy meter. Then the rotating cylinder 423 drives the driving plate 421 to rotate 90°, so that the two clamping plates clamp the electric energy meter, and the label is attached to both sides of the electric energy meter. Then the air pump 470 blows air into the cavity, and uses the positive pressure gas to apply a certain pressure to the label to make the label adhere more firmly; finally, the rotating cylinder 423 rotates 90° again to loosen the electric energy meter, the lifting cylinder 431 rises, and the stopping cylinder 461 retracts, completing the labeling work of one electric energy meter, and can paste labels on both sides of the electric energy meter at one time.

[0066] It should be understood that in this embodiment, the electric energy meters in the tray 11 are arranged in two rows and three columns, and there are three groups of stopping components, which can make the three columns of electric energy meters align with the mechanical gripper in turn; there are two mechanical grippers in the labeling mechanism, the labeling machine 442 prints four labels at a time, and the pushing block 452 pushes the master tape 443 with four labels between the two mechanical grippers, so that the four labels are respectively aligned with the two pairs of clamping plates on the two mechanical grippers, and the information on the two labels corresponding to each pair of clamping plates is the same.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
