Description

Technical Field

[0001] The present application relates to the technical field of electronic instruments, and in particular to an electric energy measurement method, device, equipment and storage medium. Background Art

[0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric meter or kilowatt-hour meter. Existing electric energy meters often measure energy through dedicated metering chips, and use a single-chip microcomputer to read the electric energy of the metering chip to accumulate the electric energy or read the power of the metering chip for integral calculation to accumulate the electric energy. When there are two or more metering chips in the electric energy meter solution, it is impossible to directly read the electric energy in the metering chip to accumulate the electric energy. It is necessary to read the power of each metering chip for integral calculation to accumulate the electric energy. When accumulating electric energy, the power of each metering chip is usually read separately at the same time for calculation. However, when the power update cycles of the two metering chips are not synchronized, there is no problem in verifying the metering accuracy on the standard bench in the laboratory, but when the load changes rapidly when the meter is running on site, inaccurate metering often occurs.

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application, and different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments recorded. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, although the embodiment may not be clearly recorded in the following text.

[0037] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims.

In addition, features described in some examples may be combined in other examples.

[0038] See also Figure 1 , Figure 1 : is a flow chart of an electric energy measurement method provided in an embodiment of the present application. In the embodiment of the present application, the method includes:

[0039] Step S110, obtaining a preset power update period of the electric energy meter.

[0040] In this embodiment, at least two types of metering chips are used to detect power-related data, and the difference between the at least two types of metering chips is that the detection frequencies of the two types are different. The metering period of one type of metering chip is an integer multiple or close to an integer multiple of the metering period of the other type of metering chip, and thus, the larger metering period is determined as the preset power update period of the electric energy meter.

[0041] Step S120: using the first metering chip to collect detection data of the electric energy meter multiple times in each preset power update period to obtain a first electric energy parameter, and using the second metering chip to collect detection data of the electric energy meter in the preset power update period to obtain a second electric energy parameter.

[0042] In this embodiment, within a preset power update cycle, the first metering chip can be used to collect detection data of the electric energy meter multiple times, and the second metering chip can be used to collect detection data of the electric energy meter once. Both complete a measurement at the end of the preset power update cycle, thereby achieving data synchronization.

[0043] In one possible implementation, step S120, using the first metering chip to collect detection data of the electric energy meter multiple times in each preset power update period to obtain the first electric energy parameter, includes:

[0044] The first metering chip is used to collect detection data of the electric energy meter multiple times with the first sub-period as the collection period to obtain the first electric energy parameter; the first sub-period is less than the preset power update period.

[0045] In this embodiment, the metering period of the second metering chip is greater than the metering period of the first metering chip. Exemplarily, the metering period of the second metering chip is T2 as the preset power update period, and the first sub-period corresponding to the first metering chip is T1, then the two satisfy T2=k×T1, k is a positive integer. Correspondingly, the first metering chip collects the detection data of the electric energy meter k times in each preset power update period.

[0046] In one possible implementation, the detection data includes a power parameter; and the first metering chip is used to collect the detection data of the electric energy meter multiple times in each preset power update cycle to obtain the first electric energy parameter, including:

[0047] An average value of power parameters collected in multiple first sub-periods is used as the first electric energy parameter.

[0048] In this embodiment, the power parameters collected in different sub-periods may be different. Therefore, the power parameters collected in multiple first sub-periods are accumulated and averaged, and the average value is used as the first electric energy parameter, thereby reducing accidental errors and improving measurement accuracy.

[0049] In one possible implementation, the detection data includes voltage parameters and current parameters; step S120, using the first metering chip to collect the detection data of the electric energy meter multiple times in each preset power update period to obtain the first electric energy parameter, including: using the following formula to obtain the first electric energy parameter:

[0050]

[0051] Among them, a1, a2, a n are the voltage parameters or current parameters collected respectively, and n is the number of collection times corresponding to a single preset power update cycle.

[0052] Because the output of the voltage and current measurement chip is an effective value, its measurement method is different from the power measurement method. Here, the voltage parameters and current parameters are determined by the above formula. According to the energy calculation formula, the power parameters can be easily determined by the voltage parameters and current parameters.

[0053] In one possible implementation, step S120, using the second metering chip to collect detection data of the electric energy meter at a preset power update period to obtain a second electric energy parameter, includes:

[0054] The second metering chip is used to collect detection data of the electric energy meter at a preset power update period; the detection data includes power parameters, voltage parameters and current parameters;

[0055] A power parameter, a voltage parameter and a current parameter are determined as second electrical energy parameters.

[0056] Since the second metering chip collects the electric energy meter data only once in a preset power update cycle, the collected power parameters, voltage parameters and current parameters can be directly determined as the second electric energy parameters, and the electric quantity parameters can be obtained through the energy calculation formula.

[0057] Step S130: determining a target electric energy parameter of the electric energy meter based on the first electric energy parameter and the second electric energy parameter.

[0058] In this embodiment, the average of the calculation results of the first electric energy parameter and the second electric energy parameter is used as the target electric energy parameter.

[0059] In one possible implementation, step S130, determining a target electric energy parameter of the electric energy meter based on the first electric energy parameter and the second electric energy parameter, includes:

[0060] The target electric energy parameters of the electric energy meter are determined by performing calculations based on the power parameters, current parameters and voltage parameters.

[0061] In this embodiment, the current parameter, voltage parameter or power parameter can be used to calculate and determine the target electric energy parameter of the electric energy meter, that is, the corresponding electric quantity data. Here, it can include calculating the data of multiple first sub-periods within a preset power update cycle and calculating the data within multiple preset power update cycles.

[0062] In one possible implementation, step S130, determining a target electric energy parameter of the electric energy meter based on the first electric energy parameter and the second electric energy parameter, includes:

[0063] The target electric energy parameter of the electric energy meter is determined based on the average value of the first electric energy parameter and the second electric energy parameter and the following formula:

[0064] E = P × AT;

[0065] Wherein, P represents the average power value, and ΔT represents the preset power integration period.

[0066] In this embodiment, taking power parameters as an example, a target power parameter of a preset power update cycle or a first sub-cycle can be determined. It should be noted that the target power parameter of the power meter can also be determined by the formula E=UI×ΔT, where U represents the voltage parameter and I represents the current parameter.

[0067] In a specific example, the metering period T1 corresponding to the first metering chip (exemplarily, such as Renergy RN8215) is about 71.111ms, and the metering period T2 of the second metering chip (exemplarily, such as Wangao V9240) is 640ms. The program designs a 1 / 2048 second (0.4882ms) timer, which reads the power, voltage, current and other metering data of the first metering chip once every 146 times, about 71.289ms. After the 9th reading of the data of the first metering chip is completed in 9 consecutive times, the metering data of the second metering chip is read once, that is, the metering data of the second metering chip is read once in 641.601ms. The first metering chip completes 9 data collections, and the power data read 9 times is accumulated and divided by 9 to obtain the average value. The formula for the power average value is: (P1+P2+…P9)÷9, P1, P2…P9 represent 9 consecutive power values ​​obtained according to the metering update period; the voltage average value calculation formula is: The calculation method of the current average value is the same as that of the voltage. Based on the collected two-way metering data, a series of operations such as power direction judgment, four-quadrant judgment, starting current judgment, power error compensation, bypass judgment, instantaneous quantity sampling data conversion into actual effective value, frequency calculation, angle calculation, metering mode judgment, etc. can be performed, and then the power integral calculation is performed according to the power value to accumulate the electric energy. Specifically: Taking active energy measurement as an example, the pulse equivalent of the energy meter is: 1kWh÷pulse constant; the integral period electric energy accumulation calculation formula is: E=P×ΔT; P: represents power, ΔT: integral period, which represents 1 / 2048 of a second (0.4882 milliseconds) in this example; in this example, the pulse constant can be 1000, then a pulse equivalent is 1Wh or 3600Ws. In the program, an energy accumulation register a is opened, and the power value read is accumulated into a every 1 / 2048 second (0.4882 milliseconds). When the value of a is greater than or equal to a pulse equivalent, the energy is increased by 0.001 kWh, and a minus a pulse equivalent value is accumulated to start accumulation. In this way, the energy accumulation is completed by cyclic accumulation. It should be noted that the above execution operations can be realized through the preset program, which will not be described one by one.

[0068] The embodiment of the present application obtains corresponding electric energy parameters by utilizing different metering chips to collect detection data of the electric energy meter multiple times at different collection frequencies within each preset power update cycle. The collection cycle of one metering chip is the same as the preset power update cycle of the electric energy meter, and the collection cycle of the other metering chip is less than the preset power update cycle of the electric energy meter. However, after the multiple sampling cycles are superimposed, they coincide with the preset power update cycle of the electric energy meter, thereby achieving data synchronization, and determining the target electric energy parameters of the electric energy meter based on the synchronized data, ensuring that the metering results can be accurately obtained even when the load changes rapidly, thereby greatly improving the accuracy of electric energy measurement.
