DETAILED DESCRIPTION
[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0018] Reference Figure 1 As shown, a branch circuit energy regulation method based on power equipment includes: S100, based on the database system, obtaining the branch road historical data of the power equipment and the branch road quantity information of the power equipment; S200, based on data cleaning, preprocessing the historical data of the branch circuits of the power equipment to obtain preprocessed historical data; S300, analyzing the preprocessed historical data, constructing a rectangular coordinate system, and drawing a branch output power change curve and a branch temperature change curve; S400, based on the database system, respectively compare and judge the branch output power change curve and the branch temperature change curve to obtain the branch load condition; S500, analyzing the load of the branch road based on the branch road load condition and the branch road quantity information, and determining the branch road energy control plan; It will be understood by those skilled in the art that the power equipment supplies power to the power consumption area through the branch line. When the power consumption area needs a large amount of electric energy, the output power of the branch line will increase. When the output power increases, the temperature of the branch line surface will increase. When the temperature of the branch line surface is higher than the set value, the branch line is in overload operation. When the branch line is overloaded for a long time, not only will the service life of the branch line be reduced, but the high temperature may also cause a fire. Therefore, by analyzing the temperature and output power of the branch line of the power equipment, when a branch line is overloaded, the excess power will be adjusted to a normal branch line or an idle branch line, so that the overloaded branch line is transformed into a normally operating branch line. At the same time, the temperature of the branch line surface will also be reduced to avoid fire, reduce safety hazards, and increase the service life of the branch line.
[0019] Reference Figure 2 As shown, based on data cleaning, data preprocessing is performed on the branch road historical data of the power equipment, and obtaining the preprocessed historical data specifically includes the following steps: S201. Based on a database system, obtain the factory specification data of the branch circuit of the power equipment, wherein the factory specification data of the branch circuit includes the branch circuit temperature data, the branch circuit output power data, the temperature-output power mapping relationship and the branch circuit overload operation data; wherein the branch circuit overload operation data is specifically the branch circuit overload temperature data; S202, based on the branch temperature data and the branch output power, searching and processing the branch historical data of the power equipment to obtain the data missing position, wherein the data missing position is any one or any two of the branch temperature data missing position and the branch output power missing position; S203, based on the temperature-output power mapping relationship, fill in the data missing position with data to obtain first preprocessed data; S204, based on the temperature-output power mapping relationship, performing outlier elimination processing on the first preprocessed data to obtain second preprocessed data; S205, performing duplicate value search and deletion processing on the second pre-processed data based on the branch temperature data and the branch output power to obtain pre-processed historical data; In this embodiment, there will be data outliers in the historical data of the branch road. In order to make the subsequent branch road energy control plan more accurate, the data outliers are deleted to avoid interference. At the same time, the data missing is filled to expand the data analysis scope and make the subsequent analysis results more accurate. In addition, in order to shorten the data analysis time, the duplicate data is removed. It is worth noting that when the output power of the branch road increases, the temperature of the branch road will increase. Therefore, the temperature-output power mapping relationship is introduced here for analysis.
[0020] Reference Figure 3 As shown, based on the temperature-output power mapping relationship, data is filled in the data missing position, and obtaining the first pre-processed data specifically includes the following steps: S2031, if the data missing position is a temperature missing position; S2032, based on the temperature-output power mapping relationship, search the branch output power corresponding to the temperature missing position in the branch factory specification data to obtain temperature filling data; S2033, filling the temperature filling data into the temperature missing position; S2034: If the data missing position is an output power missing position; S2035, based on the temperature-output power mapping relationship, searching the branch road factory specification data through the branch road temperature data corresponding to the output power missing position to obtain the output power filling data; S2036, filling the output power filling data into the output power missing position; S2037. If the data missing position is a temperature missing position or an output power missing position, delete the data missing position; In this embodiment, when the data missing position is a temperature missing position or an output power missing position, the filling data can be obtained according to the temperature-output power mapping relationship. When the data missing position is a temperature missing position and an output power missing position, the filling data cannot be obtained according to the temperature-output power mapping relationship. Therefore, the data missing position needs to be deleted.
[0021] Reference Figure 4 As shown, based on the analysis of pre-processed historical data, a rectangular coordinate system is constructed to draw the branch power change curve and the branch temperature change curve, which specifically includes the following steps: S301, construct rectangular coordinate systems based on time, branch output power and branch temperature data, respectively, set the X-axis with time as a parameter, set the Y-axis with branch output power and branch temperature data as parameters, and obtain a time-branch output power rectangular coordinate system and a time-branch temperature data rectangular coordinate system; S302 , based on the time-branch output power rectangular coordinate system and the time-branch temperature data rectangular coordinate system, respectively draw curves with time, branch output power and time, branch temperature data to obtain branch output power change curves and branch temperature change curves.
[0022] Reference Figure 5 As shown, based on the database system, the branch output power change curve and the branch temperature change curve are compared and judged respectively, and the branch load condition is obtained, which specifically includes the following steps: S401, setting a branch path temperature threshold based on branch path temperature data; S402, setting a branch output power threshold based on the branch output power data, the temperature-output power mapping relationship and the branch temperature threshold; S403.

[0023] Reference Figure 6 As shown, based on the branch output power data, the temperature-output power mapping relationship and the branch temperature threshold, setting the branch output power threshold specifically includes the following steps: S4021, based on the branch road overload temperature data, searching and processing the branch road temperature data to determine the branch road dangerous temperature data; S4022, setting the branch road dangerous temperature data as the branch road temperature threshold; S4023, based on the branch temperature threshold and the temperature-output power mapping relationship, searching and processing the branch output power data to determine the dangerous output power of the branch; S4024, setting the branch dangerous output power to a branch output power threshold; In this embodiment, since the material of the branch road has a certain high temperature resistance, it is necessary to obtain the branch road overload temperature data based on the branch road factory specification data. The branch road overload temperature data is the temperature at which the branch road may cause a fire. Therefore, the branch road overload temperature data is retrieved from the branch road temperature data to determine the branch road temperature threshold, and then the branch road output power threshold is obtained based on the temperature-output power mapping relationship and the branch road temperature threshold.
[0024] Reference Figure 7 As shown, based on the branch temperature threshold and the branch output power threshold, the branch temperature change curve and the branch output power change curve are analyzed respectively, and the branch load condition is obtained, which specifically includes the following steps: S4031, based on the branch temperature threshold and the branch output power threshold, draw a constant function curve in the time-branch temperature data rectangular coordinate system and the time-branch output power rectangular coordinate system respectively to obtain a branch temperature threshold straight line and a branch output power threshold straight line; S4032, performing intersection analysis based on the branch temperature threshold straight line, the branch output power threshold straight line, the branch temperature change curve, and the branch output power change curve to obtain a temperature intersection and an output power intersection; S4033, based on the temperature intersection, analyzing the branch road temperature change curve, obtaining the branch road overload operation time and the number of branch roads corresponding to the branch road overload operation time; S4034, based on the output power intersection point and the branch overload operation moment, analyzing the branch output power change curve, obtaining the branch output power information corresponding to the branch overload operation moment and the branch output power information of the branch normal operation; In this embodiment, in order to more intuitively reflect the readability of the data, the branch temperature threshold line, the branch output power threshold line, the branch temperature change curve, and the branch output power change curve are drawn for intersection analysis. The branch temperature data and the branch output power above the branch temperature threshold line and the branch output power threshold line are branches that are overloaded, and the branch temperature data and the branch output power below the branch temperature threshold line and the branch output power threshold line are branches that are operating normally.
[0025] Reference Figure 8As shown, based on the branch road load situation and branch road quantity information, the branch road load is analyzed and the branch road energy control scheme is determined, which specifically includes the following steps: S501, judging and processing based on the number of branch roads corresponding to the moment of branch road overload operation and the number of branch roads of the power equipment; S502: If the number of branches corresponding to the moment of overload operation of the branch is equal to the number of branches of the power equipment, and there is no branch output power information of the branch in normal operation, all branches of the output power equipment are overloaded, and additional power equipment is required; S503. If the number of branches corresponding to the moment when the branch is overloaded is less than the number of branches of the power equipment, analyze and process the branch output power information corresponding to the moment when the branch is overloaded and the branch output power information when the branch is operating normally, and design a branch energy control plan.
[0026] Reference Fig. 9 As shown, the branch road output power information corresponding to the branch road overload operation moment and the branch road output power information of the branch road normal operation are analyzed and processed, and the branch road energy control scheme is designed, which specifically includes the following steps: S5031. Analyze the branch circuit operation status of the power equipment based on the branch circuit overload operation time to determine whether there is an idle branch circuit; S5032, if there is an idle branch road, analyzing the branch road output power information corresponding to the overload operation moment of the branch road, obtaining the overload output power, and regulating the overload output power to the idle branch road for power output; S5033, if there is no idle branch road, analyzing the branch road output power information corresponding to the overload operation moment of the branch road, obtaining the overload output power, and adjusting the overload output power to the branch road in normal operation; S5034, judging and processing based on the overload output power regulation to the branch road of normal operation; S5035, after adjusting the overload output power to the normally operating branch, monitor the temperature of the normally operating branch to obtain the real-time temperature of the normally operating branch; S5036: If the real-time temperature of the normally operating branch is less than or equal to the branch temperature threshold, output that all branches are operating normally and there is no overload operation; S5037, if the real-time temperature of the normally operating branch is greater than the branch temperature threshold, the normally operating branch cannot meet the overload output power, there is an overloaded branch, and additional power equipment is required; In this embodiment, when there is an overloaded branch road, the excess power is regulated to the normally operating branch road or the idle branch road for output to avoid long-term overload operation of the branch road. At the same time, the idle branch road is operated so that each branch road is in a normal operating state. When the normally operating branch road cannot meet the output power regulated by the overloaded branch road, in order to avoid causing a fire, it is necessary to increase power equipment and branch roads to reduce safety hazards.
