[0056] In order to more clearly illustrate the technical solution of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are merely embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0059] Figure 3 A schematic diagram of the structure of a power equipment inspection system based on a drone provided by an embodiment of the present invention; DETAILED DESCRIPTION

[0060] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0061] Example 1

[0062] like Figure 1 As shown, an embodiment of the present invention provides a power equipment inspection method based on a drone, comprising:

[0063] Step 101: obtain the current wind speed, wind direction, and temperature and voltage of each power device in the target area, and perform normalization processing.

[0064] The current wind speed, wind direction, temperature and voltage of each power equipment in the target area are obtained by removing missing values, and then normalizing them to unify different types of data into the [0,1] interval.

[0065] Step 102 : determining an evaluation value of each power device according to the normalized wind speed, wind direction, and the temperature and voltage of each power device.

[0066] For example, the evaluation value of each electrical device is calculated according to the following formula:

[0067]

[0068] Among them, F i is the evaluation value of power equipment i; a is the first preset coefficient; is the normalized wind speed; is the normalized wind direction; b is the second preset coefficient; T i is the normalized temperature of the power equipment i; c is the third preset coefficient; U i is the normalized voltage of power device i; the weight coefficient is determined according to the actual situation of each power device. If the temperature of the power device has a great influence on the operation, then the value of b is set higher; if the voltage of the power device has a great influence on the operation, then the value of c is set higher, ensuring that a+b+c=1.

[0069] Step 103 : Arrange the evaluation values ​​of all the power equipment in descending order to serve as the current inspection order of all the power equipment in the target area.

[0070] The larger the evaluation value, the higher the inspection priority, and the order of power equipment inspection is adjusted in real time.

[0071] Step 104: Determine the time required to complete inspection of all power equipment in the target area according to the current inspection sequence.

[0072] In this embodiment, the Euclidean distance analysis method can be used to solve the distance between each two power devices. Taking the distance between power devices i and j as an example, the coordinates of power device i are (x i ,y i ), the coordinates of power equipment j are (x j ,y j ), the distance d between power equipment i and power equipment j ij , the formula is:

[0073]

[0074] Similarly, calculate the distance between all electrical equipment.

[0075] For example, the time T required to complete the inspection of all power equipment in the current inspection order is calculated according to the following formula:

[0076]

[0077] Where m is the total number of power equipment in the target area; t ij is the flight time of the UAV from power equipment i to power equipment j; e i is the time it takes for the UAV to complete the inspection of power equipment i; v is the flight speed of the UAV; d ij The distance from power equipment i to power equipment j; is the normalized wind speed; is the normalized wind direction.

[0078] Step 105: Obtain the power levels of all drones before and after the inspection.

[0079] Step 106 , determining the fitness value based on the time taken to complete the inspection of all power equipment in the target area, the power levels of all drones before the inspection, and the power levels after the inspection.

[0080] For example, with the minimum inspection time as the goal, the fitness value δ is calculated according to the following formula:

[0081]

[0082] Wherein, w1 is the fourth preset coefficient; T is the time to complete the inspection of all power equipment in the current inspection order; w2 is the fifth preset coefficient; Q st The power of all drones before inspection; Q end=The power consumption of all drones after the inspection is completed. Because the total inspection time factor is more important, in this embodiment, the fourth preset coefficient (weight coefficient) w1 = 0.7 and the fifth preset coefficient (weight coefficient) w2 = 0.3 are set.

[0083] Step 107: Determine the power equipment that each drone needs to inspect based on the fitness value.

[0084] Exemplarily, this step includes:

[0085] Randomly select a drone and a power equipment to form a first combination (n', m'), traverse all drones and power equipment to obtain multiple first combinations; where n' is the drone number; n' = 1, 2, ..., n; n is the total number of drones participating in the inspection; m' is the power equipment number, m' = 1, 2, ..., m; m is the total number of power equipment in the target area.

[0086] When the inspection of all electric power equipment can be completed, some first combinations are selected from all first combinations to obtain second combinations.

[0087] Traverse all first combinations to obtain multiple second combinations.

[0088] Determine the fitness value corresponding to each second combination, and select the second combination corresponding to the maximum fitness value as the final combination to determine the power equipment that each drone needs to inspect.

[0089] After obtaining the optimal inspection strategy, the inspection result visualization process is as follows: Figure 2As shown, the intelligent inspection system first calls upon the drone module and task module according to the optimal inspection strategy. The drone module primarily includes the drone's number, name, battery level, and drone status, including idle, working, charging, and faulty. The task module includes the planned drone's mission start and end points, inspection route, and execution time. Based on the combination of the optimal inspection strategy, a drone with the corresponding number and battery level is selected and the inspection task is executed along the inspection route. Then, during the inspection process, the inspection module in the intelligent inspection system is called upon to record the inspection time, device number, device name, and real-time device status for the corresponding point. Finally, these inspection results are displayed in real time on a multi-platform visual interface. The visual interface is designed using a convenient drag-and-drop designer. The interface designer includes a component selection area for displaying components to be configured, such as a time selection box, transformer, and transmission line; a design area for designing the specific display page; and a component property setting area for configuring the properties of the selected component. By dragging the relevant equipment for the inspection task from the component selection area to the design area, you can configure the component name, component style, component data source, etc. After clicking "Save", the design area will be generated and used as the final interface. When the drone inspects the corresponding point, the inspection module will find the corresponding component in the interface through the linkage relationship bound to the data source and display the real-time inspection results on the interface.

[0090] In summary, the drone-based power equipment inspection method provided in this embodiment collects meteorological data (wind speed and direction) and power equipment operating status data (temperature and voltage) during the inspection period, establishes an evaluation index system, constructs a comprehensive evaluation model, and adjusts the order of planned power equipment inspections in real time, overcoming the dynamic impact of meteorological data and power equipment operating status data on the inspection process. The fitness value is calculated for each combination of the initial inspection plan and the real-time adjusted plan, and the results are continuously updated with the larger fitness value until the maximum fitness value is selected as the final result. The current combination is then output as the optimal inspection strategy.
