[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or modules is not limited to the listed steps or modules, but may optionally include steps or modules not listed, or may optionally include other steps or modules inherent to such processes, methods, products, or apparatus.

[0045] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0046] Figure 1 This is a flowchart illustrating a method for detecting meter errors provided in an embodiment of this application, as shown below. Figure 1 As shown, the meter error detection method provided in this application embodiment may include, but is not limited to, the following steps and combinations thereof.

[0047] Step 101: Obtain the target electrical signal and the first pulse value of the meter error detection device, as well as the target pulse signal and the second pulse value of the meter under test; the target electrical signal includes at least voltage and current signals; the first pulse value includes the factory-set pulse value; the target pulse signal includes at least two pulse signals at adjacent times; the second pulse value includes the pulse value of the meter under test input externally.

[0048] For example, the target electrical signal can be the voltage and current signal output from the transmission line where the meter under test is located. The method of acquiring the target electrical signal can be determined according to the actual situation. As an example, the target electrical signal can be acquired by an electrical signal detector. Specifically, the meter error detection device can include a counter, which can be connected to the electrical signal detector. The counter can be a metering chip (e.g., a metering chip HT7032). The electrical signal detector can include at least one of an open-type current transformer and a voltage clamp (e.g., a voltage clip). The open-type current transformer and the voltage clamp can be connected to the transmission line where the meter under test is located. The open-type current transformer is a commonly used electrical device in power systems for measuring large AC currents. The voltmeter clamp can be used to connect the voltmeter to the circuit under test. The voltmeter is connected to the circuit through pins or clips in the clamp to achieve voltage measurement.

[0049] For example, the first pulse value can be the pulse value input by the process personnel in the factory where the meter error detection device is located, specifically, it can be the default pulse constant H1 of the meter error detection device. The method of obtaining the first pulse value can be determined according to the actual situation and is not limited here. As an example, the first pulse value can be received from a host computer. Specifically, the meter error detection device can include a processor, which can be connected to the host computer. The processor can be a control chip (e.g., a microcontroller FM33AO48B). The host computer refers to a computer that can directly issue control commands. The host computer can respond to the pulse value input by the process personnel in the factory where the meter error detection device is located and send the first pulse value to the processor of the meter error detection device.

[0050] As an example, after obtaining the first pulse value, the counter can be calibrated. Specifically, the counter can be used to obtain the voltage parameter to be calibrated, and a calibration coefficient can be determined based on the voltage parameter to be calibrated and the standard voltage parameter. The voltage parameter to be calibrated is then calibrated according to the calibration coefficient. For example, if the standard voltage parameter is 5A and the voltage parameter to be calibrated is 5.1A, the calibration coefficient is determined to be 0.98, so that the product of the voltage parameter to be calibrated and the calibration coefficient equals the standard voltage parameter, thus completing the calibration.

[0051] Here, the default pulse constant H1 is the number of pulses per kilowatt-hour, and the unit of the default pulse constant H1 is imp / kWh. Due to different pulse constants, when recording the same amount of electrical energy, the energy meter with a smaller pulse constant has fewer pulses, and the energy meter with a larger pulse constant has more pulses. In this embodiment, the default pulse constant H1 can be 1000 imp / kWh, which indicates that the pulse indicator light of the meter error detection device flashes when electricity is used. When the pulse indicator light flashes 1000 times, the unit value of the register will increase by one digit, indicating that 1 kilowatt-hour (kWh) of electricity has been used.

[0052] For example, the pulse signal can be a periodic electrical signal output by the meter based on the energy consumption. For instance, the meter outputs a pulse signal every time a certain amount of energy is consumed. The method for acquiring the target pulse signal can be determined according to the actual situation and is not limited here. As an example, the target pulse signal of the meter under test can be acquired by a pulse detector. Specifically, the pulse detector can be at least two pulse clamps (e.g., pulse clamp wires).

[0053] For example, the second pulse value can be the pulse value input by the staff at the site where the meter under test is located, specifically the meter pulse constant H2 of the meter under test. The second pulse value can be the same as or different from the first pulse value, and this is not limited here. The method of obtaining the target pulse signal can be determined according to the actual situation. As an example, the second pulse value input by the staff at the site where the meter under test is located can be received.

[0054] Step 102: Determine the target pulse data of the meter error detection device based on the target electrical signal and / or target pulse signal.

[0055] For example, the target pulse data can be the number of pulses accumulated after the meter error detection device is connected to the power transmission line, or it can be obtained by using hardware or software methods to count the pulse signals output by the meter error detection device based on the target electrical signal and / or the target pulse signal.

[0056] In some embodiments, the target pulse data includes first pulse data; determining the target pulse data of the meter error detection device based on the target pulse signal includes:

[0057] When receiving the target pulse signal sent by the meter under test, the first pulse data corresponding to the target pulse signal is acquired; the first pulse data represents the number of pulses of useful working energy of the meter error detection device.

[0058] For example, the first pulse data can be the number of useful power pulses P. When receiving the target pulse signal sent by the meter under test, the first pulse data corresponding to the target pulse signal can be obtained by reading the first pulse data corresponding to the current target pulse signal from the storage module of the meter error detection device when receiving the target pulse signal sent by the meter under test. The storage module can record the number of useful power pulses.

[0059] Here, the meter error detection device can be a smart meter, and the useful power pulse is the pulse data signal recorded by the meter that specifically consumes electrical energy. When an electrical appliance consumes electrical energy, the smart meter records a useful power pulse, indicating that the appliance has consumed a certain amount of electrical energy. The number of useful power pulses is positively correlated with the power consumption of the appliance, so the power consumption of the appliance can be calculated by the total number of useful power pulses. Useful power pulses have the characteristic of high accuracy. By counting useful power pulses to calculate the accumulated electrical energy of the meter error detection device, the accuracy of detecting the error of the meter under test can be improved.

[0060] In some embodiments, the target pulse data further includes second pulse data; determining the target pulse data of the meter error detection device based on the target electrical signal and the target pulse signal includes:

[0061] When receiving the target pulse signal sent by the meter under test, the second pulse data corresponding to the target pulse signal is determined based on the target electrical signal; the second pulse data characterizes the number of fast pulses of the useful active energy of the combined full wave of the meter error detection device.

[0062] For example, the second pulse data can be the number e of the combined full-wave positive useful work fast pulses. When receiving the target pulse signal sent by the meter under test, the second pulse data corresponding to the target pulse signal can be determined based on the target electrical signal. Specifically, when receiving the target pulse signal sent by the meter under test, power data can be determined based on the voltage and current data corresponding to the target electrical signal, and the second pulse data corresponding to the target pulse signal can be determined based on the power data. Specifically, the power data can be accumulated using a counter to obtain accumulated power data. If the accumulated power data is greater than or equal to the high-frequency pulse constant HfConst, the counter records a count of a combined full-wave positive useful work fast pulse. The high-frequency pulse constant HfConst can be a preset pulse value of the meter error detection device. In some embodiments, the number of combined full-wave positive useful work fast pulses can be stored in a storage module; when receiving the target pulse signal sent by the meter under test, the second pulse data corresponding to the current target pulse signal can be read from the storage module of the meter error detection device.

[0063] As an example, the waiting time for determining the second pulse data corresponding to the target pulse signal based on the target electrical signal can be determined from the current data corresponding to the target electrical signal. Specifically, the larger the current data, the faster the power data is accumulated, and the faster the power data can be accumulated to a value greater than or equal to the high-frequency pulse constant HfConst, resulting in a shorter waiting time for determining the second pulse data. The combined full-wave positive useful work fast pulse has the characteristic of rapid response. By counting the combined full-wave positive useful work fast pulses, the accumulated electrical energy of the meter error detection device can be calculated, thereby improving the detection speed of the meter error.

[0064] Step 103: Based on the target pulse signal, target pulse data, and first pulse value, determine the first energy data accumulated by the meter error detection device between the two pulse signals, and based on the second pulse value, determine the second energy data accumulated by the meter under test between the two pulse signals.

[0065] For example, the first energy data represents the first accumulated energy value E1 of the meter error detection device between the two pulse signals. This first accumulated energy value E1 can be obtained by subtracting the accumulated energy corresponding to the first pulse signal and the accumulated energy corresponding to the second pulse signal in the target pulse signal. The first pulse signal can be the pulse signal preceding the second pulse signal at an adjacent time. For example, the second energy data represents the second accumulated energy value E2 of the meter under test between the two pulse signals. This second accumulated energy value E2 can be obtained by dividing a preset energy data value by the second pulse value. The preset energy data can be 1 kilowatt-hour.

[0066] In some embodiments, the first energy data is the total useful energy accumulated between the two pulse signals. Exemplarily, the first energy data can be determined based on first pulse data characterizing the number of pulses representing the useful energy of the meter error detection device and second pulse data characterizing the number of rapid pulses representing the useful energy of the combined full-wave of the meter error detection device.

[0067] In some embodiments, the two pulse signals include a first pulse signal and a second pulse signal; determining the first energy data accumulated by the meter error detection device between the two pulse signals based on the target pulse signal, target pulse data, and the first pulse value includes:

[0068] Upon receiving the first pulse signal sent by the meter under test, the third energy data corresponding to the first pulse signal is determined based on the first pulse signal, the target pulse data, and the first pulse value.

[0069] Upon receiving the second pulse signal sent by the meter under test, the fourth energy data corresponding to the second pulse signal is determined based on the second pulse signal, the target pulse data, and the first pulse value.

[0070] Based on the third and fourth energy data, the first energy data accumulated by the meter error detection device between the two pulse signals is determined.

[0071] For example, the first pulse signal can be the first output pulse of the meter under test, and the second pulse signal can be the second output pulse of the meter under test; the third energy data can be the total useful energy Ec1 of the meter error detection device when the first output pulse of the meter is received. The first pulse signal can be the pulse signal preceding the second pulse signal at an adjacent time. When receiving the first pulse signal sent by the meter under test, the third energy data corresponding to the first pulse signal can be determined based on the first pulse signal, target pulse data, and first pulse value. Alternatively, when receiving the first pulse signal sent by the meter under test, the target pulse data accumulated by the current first pulse signal can be read from the storage module, and the third energy data accumulated by the first pulse signal can be determined based on the target pulse data and the first pulse value.

[0072] For example, the fourth energy data can be the total useful energy Ec2 of the meter error detection device when the second output pulse of the meter is received. When receiving the second pulse signal sent by the meter under test, the fourth energy data corresponding to the second pulse signal can be determined based on the second pulse signal, target pulse data, and the first pulse value. Specifically, when receiving the second pulse signal sent by the meter under test, the target pulse data accumulated by the current second pulse signal is read from the storage module, and the fourth energy data accumulated by the second pulse signal is determined based on the target pulse data and the first pulse value.

[0073] For example, based on the third and fourth energy data, the first energy data accumulated by the meter error detection device between the two pulse signals can be determined by subtracting the fourth and third energy data. Here, by comparing the difference between the accumulated energy of the meter error detection device and the meter under test in two adjacent pulse signals, interference in detecting the error of the meter under test can be effectively reduced.

[0074] In some embodiments, determining the first energy data accumulated by the meter error detection device between two pulse signals based on the target pulse signal, target pulse data, and the first pulse value includes:

[0075] Obtain the value of the third pulse from the meter error detection device; the value of the third pulse represents the preset pulse value of the meter error detection device.

[0076] Upon receiving the target pulse signal sent by the meter under test, the first energy data accumulated between the two pulse signals by the meter error detection device is determined based on the target pulse data, the first pulse value, and the third pulse value.

[0077] For example, the value of the third pulse can be the high-frequency pulse constant HfConst preset by the meter error detection device. The process of obtaining the value of the third pulse can be determined according to the actual situation and is not limited here.

[0078] For example, when receiving a target pulse signal from the meter under test, determining the first energy data accumulated between the two pulse signals by the meter error detection device based on the target pulse data, the first pulse value, and the third pulse value can be achieved by: determining a first pulse parameter based on the target pulse data and the third pulse value; and determining the first energy data accumulated between the two pulse signals based on the first pulse parameter and the first pulse value. Here, the first pulse parameter is the number of pulses corresponding to the target pulse signal when receiving the target pulse signal from the meter under test. This method, using the first pulse parameter determined based on the target pulse data and the high-frequency pulse constant, allows for a more accurate determination of the first energy data accumulated between the two pulse signals, thereby effectively improving the accuracy of detecting the meter error.

[0079] As an example, the two pulse signals include a first pulse signal and a second pulse signal. When receiving a target pulse signal from the meter under test, the first energy data accumulated by the meter error detection device between the two pulse signals can be determined based on the target pulse data, the first pulse value, and the third pulse value. Specifically, when receiving the first pulse signal from the meter under test, the third energy data corresponding to the first pulse signal can be determined based on the first pulse signal, the target pulse data, the first pulse value, and the third pulse value. When receiving the second pulse signal from the meter under test, the fourth energy data corresponding to the second pulse signal can be determined based on the second pulse signal, the target pulse data, the first pulse value, and the third pulse value. Based on the third energy data and the fourth energy data, the first energy data accumulated by the meter error detection device between the two pulse signals can be determined.

[0080] In some embodiments, the target pulse data includes first pulse data and second pulse data; determining the first energy data accumulated by the meter error detection device between the two pulse signals based on the target pulse data, the first pulse value, and the third pulse value includes:

[0081] Based on the second pulse data and the third pulse value, the first electrical energy parameter is obtained; the first electrical energy parameter characterizes the electrical energy data corresponding to the second pulse data.

[0082] Based on the first pulse data, the first electrical energy parameter, and the first pulse value, the first electrical energy data accumulated by the meter error detection device between the two pulse signals is determined.

[0083] For example, based on the second pulse data and the third pulse value, the first energy parameter can be obtained by dividing the second pulse data and the third pulse value. Based on the first pulse data, the first energy parameter, and the first pulse value, the first energy data accumulated by the meter error detection device between the two pulse signals can be determined by adding the first pulse data and the first energy parameter to obtain the first pulse parameter; and by dividing the first pulse parameter and the first pulse value to obtain the first energy data accumulated by the meter error detection device between the two pulse signals.

[0084] Here, the first energy parameter determined based on the second pulse data and the third pulse value, as well as the first pulse data, can be used to determine the first pulse parameter. The first pulse parameter can more accurately determine the first energy data accumulated between the two pulse signals, thereby effectively improving the accuracy of detecting the error of the meter under test.

[0085] As an example, the two pulse signals include a first pulse signal and a second pulse signal. The first energy data accumulated by the meter error detection device between the two pulse signals, based on the target pulse data, the first pulse value, and the third pulse value, can be determined as follows: When receiving the first pulse signal from the meter under test, the third energy data corresponding to the first pulse signal is determined based on the first pulse signal, the first pulse data, the second pulse data, and the first pulse value; when receiving the second pulse signal from the meter under test, the fourth energy data corresponding to the second pulse signal is determined based on the second pulse signal, the first pulse data, the second pulse data, and the first pulse value; and the first energy data accumulated by the meter error detection device between the two pulse signals is determined based on the third energy data and the fourth energy data.

[0086] As another example, determining the third energy data corresponding to the first pulse signal based on the first pulse signal, first pulse data, second pulse data, and first pulse value can be achieved by acquiring the third pulse value of the meter error detection device. When receiving the first pulse signal sent by the meter under test, the third energy data corresponding to the first pulse signal is determined based on the first pulse signal, first pulse data, second pulse data, first pulse value, and third pulse value. Similarly, determining the fourth energy data corresponding to the second pulse signal based on the second pulse signal, first pulse data, second pulse data, and first pulse value can be achieved by acquiring the third pulse value of the meter error detection device. When receiving the second pulse signal sent by the meter under test, the fourth energy data corresponding to the second pulse signal is determined based on the second pulse signal, first pulse data, second pulse data, first pulse value, and third pulse value.

[0087] In some embodiments, the target pulse signal includes a first pulse signal; the target pulse data includes a first pulse number and a second pulse number, wherein the first pulse number characterizes the number of pulses of useful active energy when the meter error detection device receives the first pulse signal; the second pulse number characterizes the number of fast pulses of the combined full-wave useful active energy when the meter error detection device receives the first pulse signal; the target electrical signal includes a first electrical signal; the first electrical signal characterizes the voltage and current signals when the meter error detection device receives the first pulse signal; the method further includes:

[0088] Upon receiving the first pulse signal from the meter under test, the number of second pulses is determined based on the first electrical signal.

[0089] The second energy parameter is obtained based on the number of second pulses and the value of the third pulse; the second energy parameter characterizes the energy data corresponding to the number of second pulses.

[0090] Based on the number of first pulses, the second electrical energy parameter, and the value of the first pulse, the third electrical energy data corresponding to the first pulse signal is determined.

[0091] For example, the first pulse number can be the number of useful active energy pulses P1 when the meter error detection device receives the first pulse signal; the second pulse number can be the number of fast pulses e1 of the useful active energy of the combined full wave when the meter error detection device receives the first pulse signal.

[0092] For example, when receiving a first pulse signal from the meter under test, determining the number of second pulses based on the first electrical signal can be achieved by: determining first power data based on the first voltage data and first current data corresponding to the first electrical signal; and determining the number of second pulses corresponding to the first pulse signal based on the first power data. The process of determining the number of second pulses based on the first power data refers to the description of determining the second pulse data corresponding to the target pulse signal based on the power data, and will not be repeated here.

[0093] For example, based on the number of second pulses and the value of the third pulse, the second energy parameter can be obtained by dividing the number of second pulses and the value of the third pulse, resulting in the second energy parameter (e1 / HfConst). Based on the number of first pulses, the second energy parameter, and the value of the first pulse, the third energy data corresponding to the first pulse signal can be determined by adding the number of first pulses and the second energy parameter to obtain the second pulse parameter (P1+(e1 / HfConst)); and dividing the second pulse parameter and the value of the first pulse to obtain the third energy data corresponding to the first pulse signal from the meter error detection device.

[0094] Here, by comparing the difference between the meter error detection device and the accumulated electrical energy of the meter under test at two adjacent pulse signals, interference in the process of detecting the error of the meter under test can be effectively reduced.

[0095] As an example, the target pulse signal also includes a second pulse signal. The target pulse data also includes a third pulse number and a fourth pulse number, wherein the third pulse number represents the number of useful active energy pulses P2 when the meter error detection device receives the second pulse signal; the fourth pulse number represents the number of fast pulses e2 of the combined full-wave useful active energy when the meter error detection device receives the second pulse signal; the target electrical signal includes a second electrical signal; the second electrical signal represents the voltage and current signals when the meter error detection device receives the second pulse signal. The method further includes: determining the fourth pulse number based on the second electrical signal when receiving the second pulse signal sent by the meter under test; obtaining a third energy parameter (e2 / HfConst) based on the fourth pulse number and the third pulse value; the third energy parameter represents the energy data corresponding to the fourth pulse number; and determining the fourth energy data corresponding to the second pulse signal according to the third pulse number, the fourth energy parameter, and the first pulse value. The process of this embodiment refers to the description of the foregoing embodiment, and will not be repeated here.

[0096] Step 104: Determine the error detection data of the meter under test based on the first and second power data.

[0097] In some embodiments, determining error detection data for the meter under test based on first energy data and second energy data includes:

[0098] The first difference is obtained by subtracting the second electrical energy data from the first electrical energy data.

[0099] The error detection data is obtained by performing a ratio calculation on the first difference and the first electrical energy data.

[0100] For example, determining the error detection data of the meter under test based on the first electrical energy data and the second electrical energy data can be achieved by subtracting the second electrical energy data from the first electrical energy data to obtain a first difference; and then dividing the first difference from the first electrical energy data to obtain the error detection data. The error detection data can be the useful work error (Error).

[0101] As an example, the error standard may include at least a first standard and a second standard. The first standard corresponds to a first error data, which may be 1%, and the first error standard indicates that the error is within 1%. The second standard corresponds to a second error data, which may be 2%, and the second error standard indicates that the error is within 2%. The error detection data and the first error data are compared. If the error detection data is less than or equal to the first error data, the error of the meter under test meets the first standard. If the error detection data is greater than the first error data and less than or equal to the second error data, the error of the meter under test meets the second standard. If the error detection data is greater than the second error data, the error of the meter under test does not meet the second standard.

[0102] Here, the meter error detection device can be connected to the meter under test on the same power line. In this embodiment, the difference between the accumulated electrical energy of the meter error detection device and the meter under test can be compared between two pulse signals at adjacent times to determine the error of the meter under test, thus effectively realizing convenient and quick detection of the accuracy of the meter under test.

[0103] As an example, a meter error detection device may include an LCD screen, which can display error detection data to on-site personnel. The error detection data is updated once for each pulse output by the meter under test. Here, the LCD screen can be a touchscreen capable of receiving input from on-site personnel, such as the value of the second pulse.

[0104] The following describes the meter error detection method provided in the embodiments of this application.

[0105] Figure 2 This is a schematic diagram showing the connection between the meter error detection device and the meter under test provided in the embodiments of this application. Figure 2 As shown, in a power transmission line field topology identification installation environment, the meter error detection device includes a control chip, a metering chip, and an LCD display. The control chip can connect to both the metering chip and the LCD display via a Serial Peripheral Interface (SPI). The control chip can also connect to a host computer via a Realty Serial Communication Interface 485 (RS485). The host computer can respond to the default pulse constant H1 input by process personnel in the factory where the meter error detection device is located, and send the default pulse constant H1 to the control chip. After obtaining the default pulse constant H1, the metering chip can be calibrated.

[0106] The metering chip can be connected to the power transmission line where the meter under test is located via an open-type current transformer and voltage clamps. The open-type current transformer and voltage clamps can be clipped onto the power transmission line where the meter under test is located. The control chip can be connected to the meter under test via two pulse clamp lines, which can acquire the pulse signals from the meter under test.

[0107] The LCD screen can be a touchscreen. On-site personnel can input the pulse constant H2 of the meter under test into the meter error detection device via the LCD screen. After waiting for a period of time, on-site personnel can read the error detection data of the current pulse constant H2 of the meter under test by viewing the LCD screen.

[0108] To measure the error of an electricity meter, the electricity meter error detection device performs the following steps:

[0109] Step 1: When the first output pulse of the meter under test is received, read the current total useful energy pulse count P1 of the meter error detection device and the combined full-wave positive useful energy fast pulse count e1 of the metering chip.

[0110] Step 2: When the second output pulse of the meter under test is received, read the current total useful energy pulse count P2 of the meter error detection device and the fast pulse count e2 of the combined full-wave positive useful energy of the metering chip.

[0111] Step 3: The formula for calculating the useful work error of the meter under test is as follows:

[0112] 1. When the first output pulse of the meter under test is received, the total useful power of the meter error detection device is Ec1=(P1+(e1 / HfConst)) / H1.

[0113] 2. When the second output pulse of the meter under test is received, the total useful power of the meter error detection device is Ec2=(P2+(e2 / HfConst)) / H1.

[0114] 3. Between the two pulses, the cumulative electrical energy of the meter error detection device is E1 = Ec2 – Ec1.

[0115] 4. Between the two pulses, the cumulative electrical energy of the meter under test is E2 = 1 / H2.

[0116] 5. Calculate the useful work error of the meter under test as Error = (E2 – E1) / E1.

[0117] In this embodiment, the on-site waiting time is related to the magnitude of the input current of the meter under test; the larger the current, the shorter the waiting time. The error value is updated once for each pulse output by the meter under test.

[0118] Figure 3This is a schematic diagram of the structure of an electricity meter error detection device provided in an embodiment of this application, as shown below. Figure 3 As shown, this application also provides an electricity meter error detection device 300; the electricity meter error detection device 300 includes at least a processor 301 and a counter 302; the processor 301 and the counter 302 are connected, wherein,

[0119] Counter 302 is used to acquire the target electrical signal of the meter error detection device; the target electrical signal includes at least voltage and current signals; second pulse data is determined based on the target electrical signal; the second pulse data characterizes the number of fast pulses of the useful active power of the combined full wave of the meter error detection device; and the second pulse data is sent to processor 301.

[0120] The processor 301 is configured to acquire a first pulse value, a target pulse signal and a second pulse value from the meter under test connected to the meter error detection device; the first pulse value includes a factory-set pulse value; the target pulse signal includes at least two pulse signals at adjacent times; the second pulse value includes the pulse value of the meter under test input externally; when receiving the target pulse signal sent by the meter under test, the processor acquires first pulse data corresponding to the target pulse signal; the first pulse data represents the number of pulses of useful active energy of the meter error detection device; based on the target pulse signal, the first pulse data, the second pulse data and the first pulse value, the processor determines the first energy data accumulated by the meter error detection device between the two pulse signals, and based on the second pulse value, determines the second energy data accumulated by the meter under test between the two pulse signals; and based on the first energy data and the second energy data, the processor determines the error detection data of the meter under test.

[0121] For example, the meter error detection device can be a smart meter. The meter error detection device can be connected to the meter under test on the same power line. In this embodiment, the difference between the accumulated electrical energy of the meter error detection device and the meter under test can be compared between two pulse signals at adjacent times to determine the error of the meter under test, thus effectively realizing convenient and quick detection of the accuracy of the meter under test.

[0122] For example, the processor can be a control chip (e.g., a microcontroller FM33AO48B), which can be connected to a host computer and receives the first pulse value sent by the host computer. The counter can be connected to the transmission line where the meter under test is located via an electrical signal detector. The counter can acquire the target electrical signal through the electrical signal detector and send the target electrical signal to the processor. The counter can be a metering chip (e.g., a metering chip HT7032). The electrical signal detector can include at least one of an open-type current transformer and a voltage clamp (e.g., a voltage clip).

[0123] For example, the processor can be connected to the meter under test via a pulse detector. The processor can acquire the target pulse signal via the pulse detector. Specifically, the meter under test can send the target pulse signal to the processor via the pulse detector. The meter error detection device may include an input device (e.g., an input keyboard or an LCD touch screen), and the processor can receive the second pulse value input by on-site personnel at the location of the meter under test via the input device.

[0124] For example, the meter error detection device may include a storage module, and the processor may be connected to the storage module. When receiving a target pulse signal sent by the meter under test, the processor may read the first pulse data corresponding to the target pulse signal from the storage module of the meter error detection device.

[0125] For example, determining the second pulse data based on the target electrical signal can be achieved by, upon receiving the target pulse signal sent by the meter under test, the counter reads the voltage and current data corresponding to the target electrical signal from the storage module to determine the power data, and then determines the second pulse data corresponding to the target pulse signal based on the power data.

[0126] For example, determining the first energy data accumulated between two pulse signals by the meter error detection device based on the target pulse signal, first pulse data, second pulse data, and first pulse value can be as follows: when receiving the first pulse signal sent by the meter under test, determining the third energy data corresponding to the first pulse signal based on the first pulse signal, first pulse data, second pulse data, and first pulse value; when receiving the second pulse signal sent by the meter under test, determining the fourth energy data corresponding to the second pulse signal based on the second pulse signal, first pulse data, second pulse data, and first pulse value; and determining the first energy data accumulated between the two pulse signals by the meter error detection device based on the third energy data and the fourth energy data.

[0127] As an example, determining the third energy data corresponding to the first pulse signal based on the first pulse signal, first pulse data, second pulse data, and first pulse value can be achieved by acquiring the third pulse value of the meter error detection device. When receiving the first pulse signal sent by the meter under test, the third energy data corresponding to the first pulse signal is determined based on the first pulse signal, first pulse data, second pulse data, first pulse value, and third pulse value. Similarly, determining the fourth energy data corresponding to the second pulse signal based on the second pulse signal, first pulse data, second pulse data, and first pulse value can be achieved by acquiring the third pulse value of the meter error detection device. When receiving the second pulse signal sent by the meter under test, the fourth energy data corresponding to the second pulse signal is determined based on the second pulse signal, first pulse data, second pulse data, first pulse value, and third pulse value.

[0128] As another example, the target pulse signal includes a first pulse signal; the target pulse data includes a first pulse number and a second pulse number, wherein the first pulse number characterizes the number of useful active energy pulses when the meter error detection device receives the first pulse signal; the second pulse number characterizes the number of rapid pulses of the combined full-wave useful active energy when the meter error detection device receives the first pulse signal; the target electrical signal includes a first electrical signal; the first electrical signal characterizes the voltage and current signals when the meter error detection device receives the first pulse signal; the method further includes: determining a second pulse number based on the first electrical signal when receiving the first pulse signal sent by the meter under test; obtaining a second energy parameter based on the second pulse number and a third pulse value; the second energy parameter characterizes the energy data corresponding to the second pulse number; and determining a third energy data corresponding to the first pulse signal according to the first pulse number, the second energy parameter, and the first pulse value.

[0129] The target pulse signal also includes a second pulse signal; the target pulse data also includes a third pulse number and a fourth pulse number, wherein the third pulse number characterizes the number of useful active energy pulses when the meter error detection device receives the second pulse signal; the fourth pulse number characterizes the number of rapid pulses of the combined full-wave useful active energy when the meter error detection device receives the second pulse signal; the target electrical signal includes a second electrical signal; the second electrical signal characterizes the voltage and current signals when the meter error detection device receives the second pulse signal. The method further includes: upon receiving the second pulse signal sent by the meter under test, determining the fourth pulse number based on the second electrical signal; obtaining a third energy parameter based on the fourth pulse number and the third pulse value; the third energy parameter characterizing the energy data corresponding to the fourth pulse number; and determining the fourth energy data corresponding to the second pulse signal according to the third pulse number, the fourth energy parameter, and the first pulse value. The process of this embodiment is described with reference to the foregoing embodiment and will not be repeated here.

[0130] Figure 4 This is a schematic diagram of the structure of another meter error detection device provided in the embodiments of this application, as shown below. Figure 4 As shown, the meter error detection device includes a control chip, which is a microcontroller FM33AO48B. The control chip is connected to the metering chip and the LCD display via SPI. The metering chip is an HT7032. The control chip is connected to an electrically erasable programmable read-only memory (EEPROM) via Inter-Integrated Circuit (I2C). The control chip is also connected to an RS485 chip and a printing module via a Universal Asynchronous Receiver / Transmitter (UART).

[0131] The control chip can receive pulse signals and / or pulse data sent by the metering chip. It can determine whether the data in the registers of the control chip and the metering chip are consistent. If they are inconsistent, the control chip sends a reset signal (Reset, RST) to the metering chip to perform a reset operation. The metering chip can be connected to at least one current transformer and can measure at least one current (e.g., Ia, Ib, Ic, ..., In). Specifically, the number of current transformers connected to the metering chip can be determined according to the number of phases of the meter under test. If the meter under test is a three-phase meter, it is connected through three current transformers; if the meter under test is a single-phase meter, it is connected through one current transformer.

[0132] The control chip is also connected to a power light, a battery, and an external power source. The control chip can send switching commands to the power light, the battery can monitor the battery voltage signal and send it to the control chip, and the external power source can provide power to the control chip when the control chip detects that it is in a power-off state.
