Embodiment 1

[0107] Such as figure 1 As shown, this embodiment provides a method for forecasting demand for measuring instruments, including the following steps:

[0108] Step 1: Obtain the historical data of the installation volume of each type of measuring instrument and the external data of each influencing factor in the corresponding period, and calculate the chi-square value of the two variables through the chi-square test. If the chi-square value is small and close to 0, install The quantity is related to external factors, and the installation type of measuring instruments is "industry expansion, new installation, transformation and rotation", go to step 2; if the chi-square value is large, it is determined that the installation quantity has nothing to do with external factors, and it is an installation type of "fault repair" , execute step 3;

[0109] Step 2: Use the SRU+RBF algorithm to make predictions, and measure the historical data of the past installation / demand of measuring ...

Embodiment 2

[0114] On the basis of Example 1, such as Figure 2-3 As shown, the SRU+RBF algorithm predicts, and the general process of forecasting the demand for measuring instruments of the installation type of "transformation rotation, business expansion and new installation" is as follows:

[0115] A1: Collect historical order data of measuring instruments and perform data preprocessing;

[0116] A1.1: Collect the historical orders of the installation types of measuring instruments for "retrofit and rotation" and "industry expansion and new installation" in the MDS system or SG186 system, and obtain the historical installation volume of each type of measuring instrument on a weekly / monthly / quarterly basis, and The historical data matrix is ​​formed according to the row direction of different models and the column direction of different weeks / months / quarters;

[0117] A1.2: In the historical data matrix, each column of data constitutes a column vector The minimum value data and maxim...

Embodiment 3

[0151] On the basis of Example 1, the SRU+Bayesian network algorithm is used for prediction. By predicting the failure of the measuring instruments in operation, the type and quantity of the measuring instruments that have failed are obtained, and the demand for "fault repair" installation type measuring instruments is calculated. Quantity P bn .

[0152] Specifically, such as Figure 4 As shown, the general process of the SRU+Bayesian network combination algorithm for forecasting the demand of the "fault repair" installation type measuring instruments is as follows:

[0153] B1: Obtain attribute data of faulty measuring instruments from the power site: collection success rate, online rate, usage time, specification and model, manufacturer, production batch, communication flow, communication protocol, channel type, and the number of important items sent , clock out-of-tolerance times, address;

[0154] B2: Perform data preprocessing on the attribute data collected in step B...

Abstract

The invention discloses a measuring instrument demand prediction method and system, a calculation device and a storage medium, belongs to the technical field of electric energy demand prediction, and solves the technical problems of low prediction accuracy and high time cost of an existing measuring instrument. Prediction is carried out through SRU + RBF and SRU + Bayesian network algorithms, and if the installation amount is related to external factors, the measurement accuracy of the measuring instrument is improved. Performing prediction through an SRU + RBF algorithm, accurately predicting the demand quantity of the measurement instruments of the installation types of'transformation rotation 'and'business expansion new installation', and outputting a prediction result; if the installation amount is irrelevant to external factors, prediction is carried out through an SRU + Bayesian network algorithm, the demand quantity of the'fault repair 'installation type measuring instrument is accurately predicted, and a prediction result is output; scientific support is provided for optimizing electric power material inventory management and reducing enterprise cost.
