Fig. 1 is a flowchart of a method for determining an operating power of an air conditioner according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
and S102, acquiring working condition parameters of the air conditioner.
In step S102, the operating parameters of the air conditioner at least include: real-time operating mode parameter and historical operating mode parameter, real-time operating mode parameter and historical operating mode parameter include at least: the method comprises the following steps of operating modes of the air conditioner and corresponding operating parameters in the operating modes, wherein the operating modes of the air conditioner at least comprise: the air conditioner comprises a refrigeration mode, a heating mode, a dehumidification mode, an air supply mode and the like, wherein different operation modes have different operation parameters, for example, the different operation modes generally comprise the following operation parameters: the operation frequency of the compressor, the rotation speed of the inner fan, the rotation speed of the outer fan, the wind sweeping angular speed of the air deflector and the like are adopted, but the operation parameters corresponding to the refrigeration mode do not include electric auxiliary heating current. In addition, the corresponding operating parameters may also be different for different types of air conditioners, for example, for an air conditioning unit without an expansion valve, the corresponding operating parameters do not include the opening degree of the expansion valve.
In addition, the real-time working condition parameter is a working condition parameter of the air conditioner in the current operation mode, and the historical working condition parameter is a working condition parameter of the air conditioner in the operation within the historical preset time length. Optionally, the processing unit of the air conditioner first detects whether the air conditioner is in a startup state; under the condition that the air conditioner is detected to be in a shutdown state, determining historical working condition parameters as working condition parameters; and under the condition that the air conditioner is detected to be in a starting state and in an operating state, determining the real-time working condition parameter as the working condition parameter. In the application, the air conditioner is provided with the acquisition unit, the acquisition unit can acquire real-time working condition parameters during the operation of the air conditioner, and the acquisition unit can also acquire historical working condition parameters input by a user. Optionally, the air conditioner further has a data storage unit, the data storage unit may store an operation mode when the air conditioner operates and an operation parameter in the operation mode, before the air conditioner operates, if a user sends an instruction to the air conditioner to check the operation power, the acquisition unit of the air conditioner may acquire the historical operating condition parameter from the data storage unit, so that the historical operating condition parameter is processed by the processing unit of the air conditioner, and the operation power of the air conditioner is predicted.
And step S104, determining a power measuring rule corresponding to the running mode.

in the above formula, WcFor operating power in cooling or dehumidifying mode, F is the compressor operating frequency, NnIs the rotation speed of the inner fan, NwThe rotation speed of an external fan, P is the opening degree of an expansion valve, V is the wind sweeping angular speed of a wind deflector, R is an integral constant term of a controller and other nonlinear elements, and K is an integral constant term of the power of other specially configured modules (such as a WIFI module, a voice module, an image recognition graph module, an infrared human-induced device module and the like). a isc、λc、βc、Φc、ωcIs a correction factor.
In the heating or air supply mode, the power measurement rule meets the following formula:
in the above formula, WhFor operating power in the cooling or dehumidification mode, the UI is an electrically assisted thermal current or voltage. a ish、λh、βh、Φh、ωhIs a correction factor.
It should be noted that the power measurement rule is not limited to the expression form shown in the above two formulas, and may be other functional forms, such as linear function, power function, exponential function, logarithmic function, and inverse function, and may also be an equation or a combination of function equations. It is not limited in this application.
And S106, determining the running power of the air conditioner in the running mode based on the power measuring and calculating rule and the running parameters.
After the power measurement rule is obtained in steps S102 and S104, the operating parameter corresponding to the real-time operating condition parameter or the operating parameter corresponding to the historical operating condition parameter is input into the formula corresponding to the power measurement rule, and the operating power corresponding to the real-time operating condition or the operating power corresponding to the historical operating condition can be obtained through the calculation formula.
Based on the schemes defined in the above steps S102 to S106, it can be known that, after the working condition parameters of the air conditioner are obtained, the power measurement rule is determined according to the operating mode in the working condition parameters by using a manner of calculating the operating power of the air conditioner by using the power measurement rule corresponding to the operating mode of the air conditioner, and then the operating parameters in the working condition parameters are processed by using the power measurement rule to obtain the operating power of the air conditioner.
It is easy to notice that the calculation of the running power can be realized without using an additional power measuring device, and the device cost of the air conditioning unit is saved. In addition, the working condition parameters of the air conditioner at least comprise real-time working condition parameters and historical working condition parameters, and therefore the working condition parameters are obtained in real time or based on the historical working conditions, and therefore the running power obtained by calculation according to the working condition parameters is necessarily real-time or can be obtained in advance before the air conditioner runs. In addition, after the working condition parameters of the air conditioner are determined, the power measurement and calculation rule corresponding to the operation mode of the air conditioner is selected to calculate the operation power, so that the calculation of the operation power of the air conditioner is more targeted, and the accuracy of the measurement and calculation of the operation power is improved.
Therefore, the purpose of measuring and calculating the operating power of the air conditioner is achieved by the scheme, the technical effect of synchronizing the operating power of the air conditioner in real time or determining the operating power of the air conditioner in advance is achieved, and the technical problem that the operating power of the air conditioner cannot be synchronized in real time or determined in advance in the prior art is solved.
In an optional embodiment, before determining the power measurement rule corresponding to the operation mode, the processing unit of the air conditioner further obtains the power measurement rule of the air conditioner in the multiple operation modes, obtains multiple function groups based on the operation parameters of the air conditioner in each operation mode and the corresponding power measurement rule, then solves the multiple function groups based on a neural network fitting algorithm to obtain multiple groups of correction coefficients, and fits the multiple groups of correction coefficients to obtain multiple groups of target correction coefficients, wherein each group of target correction coefficients corresponds to each operation mode. And finally, obtaining a power measurement rule corresponding to each operation mode based on the multiple groups of target correction coefficients.
Optionally, fig. 2 shows a flowchart for determining the operating power of the air conditioner, and as can be seen from fig. 2, the processing unit first obtains the operating parameters of the air conditioner in each operating mode, and then fits the operating parameters to obtain the power measurement rule corresponding to each operating mode. Specifically, the collecting unit of the air conditioner collects the operating parameters of the air conditioner during normal operation in each operating mode, and inputs the operating parameters collected in each operating mode into the formula corresponding to the corresponding power measuring and calculating rule, so as to obtain a plurality of function groups, for example, for a refrigeration or dehumidification mode, the expression form of the plurality of function groups may be:
for the heating or blowing mode, the expression form of the function groups can be as follows:
after obtaining the plurality of function groups, the processing unit uses a neural network fitting algorithm to solve the function groups to obtain correction coefficients. The Neural network fitting algorithm may be a fitting algorithm based on a bp (back propagation) Neural network, an RNN (Recurrent Neural network), and a CNN (Convolutional Neural network).
Optionally, the processing unit randomly selects a preset number of functions from each group of functions to form a function group, where the preset number is at least 5 (or other groups), as shown in fig. 2, W in the cooling or dehumidifying mode is selected respectivelyc1、Wc2、Wc3、Wc4、Wc5And W in heating or blowing modeh1、Wh2、Wh3、Wh4、Wh5And constitute a function group. Then, the function group is solved by using a language program such as C/C + +/Python or a related computing device by an iterative method or other effective solving methods to obtain a group of correction coefficients. The above processes are repeatedly executed, and then a plurality of groups of correction coefficients can be obtained. Further, after obtaining multiple groups of correction coefficients, fitting multiple groups of correction systems based on probability theory and mathematical statistics to obtain target correction coefficients, such as a in fig. 2c、λc、βc、Φc、ωcAnd ah、λh、βh、Φh、ωh。
And finally, the processing unit inputs the target correction coefficient into a formula corresponding to the corresponding original power measurement and calculation rule to obtain a final power measurement and calculation rule. After the power measurement rule is obtained, the real-time operation power of the air conditioner can be calculated based on the power measurement rule and the real-time working condition parameters of the air conditioner.
Further, after determining the operating power of the air conditioner in the operating mode based on the power measurement and calculation rule and the operating parameter, the processing unit further updates the target correction system in the power measurement and calculation rule based on the operating parameter to obtain an updated correction coefficient, and obtains a latest power measurement and calculation rule based on the updated correction coefficient.
It should be noted that, because the data amount input into the processing unit is gradually increased due to the long accumulation of the air conditioner running time, in practical applications, the target correction system can be automatically updated in real time, and then the formula corresponding to the power measurement rule is automatically updated in real time, thereby improving the power measurement accuracy.
In addition, the air conditioner also has an output unit, which may be a display. After the operating power is obtained, the output unit can also display the operating power in real time, or the processing unit sends the operating power to other modules for recording or processing.
According to the scheme, the power measuring device (or the power detector and the like) is not required to be additionally arranged to measure the power of the whole air conditioning unit, and the cost of the air conditioning unit is reduced. In addition, the scheme provided by the application can realize synchronous and accurate measurement and calculation of the real-time operating power of the air conditioner or accurate prediction of the operating power of the air conditioner in advance, so that the air conditioner can conveniently distribute and control the operating power of the air conditioner in the later period, and the energy-saving and efficient operation is realized.

In an alternative embodiment, as shown in fig. 3, the processing unit includes three unit modules, namely, unit module 1, unit module 2, and unit module 3, which are respectively used to determine a plurality of sets of correction coefficients, generate a target correction coefficient, and generate a power estimation rule.
Specifically, the unit module 1 inputs the operating condition parameters acquired by the acquisition unit into a corresponding formula to generate a plurality of function groups, and solves the function groups by using a neural network fitting algorithm to obtain a plurality of groups of correction coefficients. The unit module 2 performs fitting processing on the multiple groups of correction coefficients by using methods such as probability theory and mathematical statistics, and generates target correction coefficients. The unit module 3 is used for replacing the target correction coefficient and substituting the target correction coefficient into a formula of the corresponding power measurement rule, and updating and automatically generating the latest power measurement rule in real time.
As can be seen from the above, the operating power of the air conditioner is calculated by using the power measurement rule corresponding to the operating mode of the air conditioner, after the operating condition parameters of the air conditioner are obtained, the power measurement rule is determined according to the operating mode in the operating condition parameters, and then the operating parameters in the operating condition parameters are processed by using the power measurement rule to obtain the operating power of the air conditioner.

In addition, the working condition parameters of the air conditioner at least comprise real-time working condition parameters and historical working condition parameters, and therefore the working condition parameters are obtained in real time or based on the historical working conditions, and therefore the running power obtained by calculation according to the working condition parameters is necessarily real-time or can be obtained in advance before the air conditioner runs. In addition, after the working condition parameters of the air conditioner are determined, the power measurement and calculation rule corresponding to the operation mode of the air conditioner is selected to calculate the operation power, so that the calculation of the operation power of the air conditioner is more targeted, and the accuracy of the measurement and calculation of the operation power is improved.
Therefore, the purpose of measuring and calculating the operating power of the air conditioner is achieved by the scheme, the technical effect of synchronizing the operating power of the air conditioner in real time or determining the operating power of the air conditioner in advance is achieved, and the technical problem that the operating power of the air conditioner cannot be synchronized in real time or determined in advance in the prior art is solved.
