[0025] The specific scheme of an electric energy meter and environmental automatic test management system and method provided by the present invention is described in detail below with reference to the accompanying drawings.

[0026] See attached Figure 1 , which shows a flow chart of an electric energy meter and environment automatic test management method provided by an embodiment of the present invention, which adopts the above-mentioned electric energy meter and environment automatic test management system, and the method includes the following steps: S1. Collect electricity meter data and laboratory environment data, divide the standardized data into multiple levels for processing, and perform multi-layer weighted fusion. Through adaptive weighting and cross-validation mechanisms, ensure the accuracy of the fused data and obtain the final fusion result.

[0027] The electric energy meter detection unit and the environmental monitoring unit collect the electric energy meter data and the environmental data inside and outside the laboratory respectively. The current sensor, voltage sensor and power sensor of the electric energy meter detection unit transmit the current, voltage, power and other parameters of the electric energy meter to the data acquisition module. The data acquisition module performs preliminary processing on the electric energy meter data, including data denoising, data smoothing, data calibration, data synchronization, etc., and then sends it to the preprocessing module; the temperature and humidity sensor and noise sensor of the environmental monitoring unit are responsible for collecting the temperature, humidity and noise data inside and outside the laboratory, and the collected environmental data is sent to the preprocessing module.

[0028] The preprocessing module performs standardization on the received electric energy meter data and environmental data. The initial electric energy meter data is , the environmental data is In order to eliminate the dimensional differences between data, the data is standardized so that its mean is 0 and its variance is 1. The standardization formula is:

[0029] in, and They are the standardized electric energy meter data and environmental data. and are the i-th electric energy meter data and the j-th environmental data, and are the mean and standard deviation of the electric energy meter data, and are the mean and standard deviation of environmental data, respectively. This ensures that data from different sources are processed on the same scale, avoiding processing errors caused by different data dimensions.

[0030] The multi-layer fusion module divides the standardized data into multiple layers for processing and performs multi-layer weighted fusion. The layered data is assumed to be and (No. layer), the initial weight is and The purpose of layered processing is to process the different characteristics of data in a more detailed manner, so that each layer of data can fully reflect its importance and characteristics during weighted fusion. The multi-layer weighted fusion formula is:

[0036] The multi-layer fusion module performs global adaptive adjustment based on the cross-validation errors at each level to obtain the final fusion result:

[0037] in, is the final fusion result. For the The global weight of the layer, is the total number of data stratification layers. The overall weight is dynamically adjusted according to the accuracy of the fusion results at each layer, so that the final fusion result can integrate the data characteristics and accuracy of each layer to achieve the optimal fusion effect.
