Thus, if one embodiment includes feature A, B, C and another embodiment includes feature B, D, then the application should also be seen as embracing one or more of all other possible combinations of one or more of A, B, C, D, although such an embodiment may not be explicitly recited in the following.

For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.
Referring to fig. 1, fig. 1 is a schematic flow chart of an electric energy measurement method according to an embodiment of the present application. In an embodiment of the present application, the method includes:
step S110, a preset power update period of the electric energy meter is obtained.
In this embodiment, the electric energy-related data is detected by at least two types of metering chips, which differ in the detection frequencies thereof. The metering period of one metering chip is an integer multiple or nearly an integer multiple of the metering period of the other metering chip, and accordingly, the larger metering period is determined as a preset power update period of the electric energy meter.
Step S120, acquiring detection data of the electric energy meter for a plurality of times in each preset power update period by using the first metering chip to obtain a first electric energy parameter, and acquiring detection data of the electric energy meter for a preset power update period by using the second metering chip to obtain a second electric energy parameter.
In this embodiment, in a preset power update period, the first metering chip may be used to collect detection data of the electric energy meter for multiple times, and the second metering chip may be used to collect detection data of the electric energy meter once, where both metering is completed once at the end of the preset power update period, so as to realize data synchronization.
In one embodiment, step S120, acquiring, by using the first metering chip, detection data of the electric energy meter for a plurality of times in each preset power update period to obtain a first electric energy parameter includes:
and acquiring detection data of the electric energy meter for a plurality of times by using the first metering chip with the first sub-period as an acquisition period to obtain a first electric energy parameter, wherein the first sub-period is smaller than a preset power update period.
In this embodiment, the metering period of the second metering chip is greater than the metering period of the first metering chip. For example, taking the metering period of the second metering chip as T2 as the preset power update period, and the first sub-period corresponding to the first metering chip as T1, both satisfy t2=kxt1, where k is a positive integer. Correspondingly, the number of times that the first metering chip collects detection data of the electric energy meter in each preset power update period is k times.
In one embodiment, the detection data includes a power parameter, and acquiring the detection data of the electric energy meter for a plurality of times in each preset power update period by using the first metering chip to obtain the first electric energy parameter includes:
And taking the average value of the power parameters acquired in the first sub-periods as a first electric energy parameter.
In this embodiment, the power parameters collected in different sub-periods may have differences, so that the power parameters collected in the first sub-periods are accumulated and averaged, and the average value is used as the first power parameter, thereby reducing accidental errors and improving measurement accuracy.
In one embodiment, the detection data includes a voltage parameter and a current parameter, and the step S120 of acquiring the detection data of the electric energy meter for a plurality of times in each preset power update period by using the first metering chip to obtain a first electric energy parameter includes obtaining the first electric energy parameter by using the following formula:
Wherein a 1、a2、an is a voltage parameter or a current parameter which is respectively acquired, and n is the acquisition times corresponding to a single preset power update period.
The output of the voltage and current metering chip is an effective value, so that the metering mode is different from the power metering mode. Here, the voltage parameter and the current parameter are determined by the above formulas. According to the energy calculation formula, the electric quantity parameter can be easily determined through the voltage parameter and the current parameter.
In an embodiment, step S120, collecting, by using a second metering chip, detection data of the electric energy meter at a preset power update period to obtain a second electric energy parameter, includes:
Collecting detection data of the electric energy meter by using a second metering chip in a preset power update period, wherein the detection data comprises a power parameter, a voltage parameter and a current parameter;
The power parameter, the voltage parameter, and the current parameter are determined as the second electrical energy parameter.
Because the second metering chip only collects the data of the electric energy meter once in a preset power updating period, the collected power parameter, voltage parameter and current parameter can be directly determined as the second electric energy parameter, and the electric quantity parameter is obtained through an energy calculation formula.
Step S130, determining a target power parameter of the power meter based on the first power parameter and the second power parameter.
In this embodiment, the average value of the calculation results of the first power parameter and the second power parameter is taken as the target power parameter.
In one embodiment, step S130, determining a target power parameter of the power meter based on the first power parameter and the second power parameter, includes:
And calculating based on the power parameter, the current parameter and the voltage parameter, and determining a target electric energy parameter of the electric energy meter.
In this embodiment, the current parameter, the voltage parameter or the power parameter may be used to perform operation, so as to determine a target electric energy parameter of the electric energy meter, that is, corresponding electric quantity data. Here, the operation may include an operation on the data of the plurality of first sub-periods within one preset power update period and an operation on the data of the plurality of preset power update periods.
In one embodiment, step S130, determining a target power parameter of the power meter based on the first power parameter and the second power parameter, includes:
determining a target power parameter of the power meter based on an average of the first power parameter and the second power parameter and the following formula:
E=P×AT;
wherein P represents the average power value and DeltaT represents the preset power integration period.
In this embodiment, taking the power parameter as an example, a target power parameter of a preset power update period or a first sub-period may be determined. It should be noted that, the target electric energy parameter of the electric energy meter may also be determined by the formula e=ui×Δt, where U represents the voltage parameter, and I represents the current parameter.
In one specific example, the metering period T1 corresponding to the first metering chip (e.g., the sharp micro RN 8215) is about 71.111ms, and the metering period T2 of the second metering chip (e.g., the high V9240) is 640ms. A 2048 minute 1 second (0.4882 ms) timer was programmed to read 1 first meter chip power, voltage, current, etc. of metering data about 71.289ms every 146 times. After the 9 th reading data in the continuous 9 times of reading the first metering chip data is completed, the metering data of the 1 times of second metering chip is read, namely 641.601ms is used for reading the metering data of the 1 times of second metering chip. The first metering chip completes 9 times of data acquisition, and adds up and divides the 9 times of read power data to obtain an average value, wherein the power average value formula is (P1+P2+. P9)/(9), the P1 and the P2.. P9 represent continuous 9 times of power values obtained according to a metering update period, and the voltage average value calculation formula is as follows: The current average value is calculated in accordance with the voltage. According to the collected two paths of metering data, power direction judgment, four-quadrant judgment, starting current judgment, power error compensation, bypass judgment and the like can be carried out, instantaneous quantity sampling data are converted into a series of operations such as actual effective values, frequency calculation, angle calculation, metering mode judgment and the like, and then power integration calculation is carried out according to power values, and electric energy is accumulated, specifically, by taking active electric energy metering as an example, pulse equivalent of an electric energy meter is 1 kWh/pulse constant, an integration period electric energy accumulation calculation formula is E=P×DeltaT, P represents power, deltaT represents integration period, 2048 minutes is 1 second (0.4882 milliseconds), and in the example, the pulse constant can be 1000, and one pulse equivalent is 1Wh or 3600Ws. In the program, an electric energy accumulation register a is opened, the read power value is accumulated into a every 2048 minutes for 1 second (0.4882 milliseconds), when the value of a is more than or equal to one pulse equivalent, the electric energy is added by 0.001kWh, and the value of a minus one pulse equivalent is started to accumulate, so that the cycle accumulation is completed. It should be noted that the above execution operations may be implemented by a preset program, which is not described in detail.
According to the embodiment of the application, the detection data of the electric energy meter are acquired for multiple times at different acquisition frequencies in each preset power update period by utilizing different metering chips, so that corresponding electric energy parameters are obtained, the acquisition period of one metering chip is the same as the preset power update period of the electric energy meter, the acquisition period of the other metering chip is smaller than the preset power update period of the electric energy meter, but the overlapping of the sampling periods is identical with the preset power update period of the electric energy meter, thereby achieving data synchronization, determining the target electric energy parameters of the electric energy meter based on the synchronous data, ensuring that metering results can be accurately acquired even when the load is changed rapidly, and greatly improving the electric energy measurement precision.
