[0060] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention.

[0061] Figure 1 The present invention is a flowchart of an intelligent control method for bird-repelling equipment used in power grids.

[0062] Figure 2 This is a structural diagram of the intelligent control system for bird-repellent equipment used in power grids. DETAILED DESCRIPTION

[0063] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0064] Figure 1 The flowchart of the intelligent control method of bird-repelling equipment for power grid is as follows. In an embodiment of the present invention, an intelligent control method of bird-repelling equipment for power grid is provided. The method includes:

[0065] Step S100: obtaining a power grid area, randomly selecting a device placement point according to the power grid area, and determining an application area of ​​the device placement point; the application area is a sub-area of ​​the power grid area, and the union of all application areas is not less than the power grid area; the device placement point is used to install the bird repellent device;

[0066] The power grid area refers to the area where birds need to be repelled, which is generally the area where the power grid lines are located. After the power grid area is obtained, some points are randomly selected according to the power grid area for installing bird repellent equipment. There are many kinds of bird repellent equipment, and the simplest one is an audio player with motion function. During the motion, the bird repellent audio is played to achieve the bird repellent effect. Since the movement range of the bird repellent equipment is limited, the influence range is also limited. Therefore, when determining the equipment placement point, the application area of ​​the equipment placement point is determined; the union of all application areas needs to cover the entire power grid area, so as to repel birds at various positions.

[0067] Step S200: creating a device matrix according to the device placement points, randomly selecting different numbers of row and column positions in the device matrix, and obtaining a test matrix set labeled by number; the value range of the number is from one to the total number of devices;

[0068] The equipment placement points determined by statistics are used to create a matrix according to the position relationship, which is called the equipment matrix. Each row and column position in the equipment matrix corresponds to the equipment placement point one by one. The equipment matrix contains the positions of all equipment placement points. In actual use, only a few bird-repelling devices are often controlled to achieve the bird-repelling effect. In this regard, steps S200 and S300 of the present application are mainly aimed at the testing phase. First, a number is determined, which represents how many bird-repelling devices are used. After the number is determined, the number of row and column positions is selected in the equipment matrix, and the selected row and column positions are marked as one, and the other positions are marked as zero. The resulting matrix is ​​called a test matrix. The size of the test matrix is ​​the same as the size of the equipment matrix. There are actually many options for selecting the number of row and column positions in the equipment matrix. Therefore, the test matrices corresponding to the same number are not unique, and these test matrices together constitute a test matrix set.

[0069] It should be noted that the value range of the quantity is from one to the total number of devices and is a positive integer.

[0070] Step S300: collecting bird-repelling utility values ​​corresponding to different test matrices according to a preset collection device, and calculating average bird-repelling utility values ​​of different quantities;

[0071] The collection device is used to record the activities of birds. On the one hand, it is used to determine whether there are birds on the route. If there are birds, a bird-repelling instruction will be generated to carry out bird-repelling activities. On the other hand, it can also record the state of the birds being driven away during each bird-repelling process, which is represented by a parameter called the bird-repelling utility value. The higher the bird-repelling utility value, the better the bird-repelling effect. Since each quantity corresponds to a test matrix set, each test matrix corresponds to a test result and also corresponds to a bird-repelling utility value. Therefore, when the quantity is used as a label, it is necessary to count the test results of all test matrices, that is, to calculate the average value of the bird-repelling utility value, which is called the average bird-repelling utility value.

[0072] Step S400: determining different numbers of selection probabilities according to the average bird-repelling utility value, and when receiving a bird-repelling instruction generated by a collection device, controlling the bird-repelling device based on the selection probability;

[0073] Different average bird-repellent utility values ​​correspond to different bird-repellent effects, and different numbers of bird-repellent devices correspond to different resource costs. By combining the bird-repellent effect and resource cost, the selection probabilities of different numbers can be determined. When the collection device detects birds on the line, the number of selected devices is determined based on the selection probability, and then the corresponding number of bird-repellent devices is activated, and the operation command is sent to drive away the birds.

[0074] As a preferred embodiment of the technical solution of the present invention, the steps of obtaining the power grid area, randomly selecting the equipment placement point according to the power grid area, and determining the application area of ​​the equipment placement point include:

[0075] Receive the total number of power grid areas and equipment input by staff;

[0076] Randomly select the total number of coordinates of the equipment in the power grid area as the equipment placement points;

[0077] Obtain the movement boundary of the bird repellent device based on the device placement point and create a movement area;

[0078] Expand the motion area based on the preset size to obtain the application area;

[0079] In the process of randomly selecting coordinates, the following conditions are met:

[0080] Where N is the total number of selected coordinates, x i is the horizontal coordinate of the i-th coordinate that has been selected, y i is the ordinate of the i-th coordinate that has been selected; x is the abscissa of the coordinate to be selected, y is the ordinate of the coordinate to be selected; A is the preset threshold.

[0081] The above content is actually the point selection process, in which the staff inputs the power grid area (a range) and the total number of equipment. The total number of equipment is related to the cost. The more equipment there are, the higher the cost. The conventional point distribution method is a uniform point distribution method with extremely high order. However, for the bird-repelling scene, the order is not good. Therefore, this application adopts a random point selection scheme, randomly selecting the total number of equipment coordinates in the power grid area as the equipment placement point, and then obtaining the motion boundary of the bird-repelling equipment based on the equipment placement point. The motion boundary is the farthest position that the audio player on the bird-repelling equipment can reach, and the area within the motion boundary is called the motion area. The motion area is expanded based on the preset size to obtain the application area. The reason for the expansion is that birds are more sensitive, and the actual impact range of the bird-repelling equipment is much larger than the motion range. The application area obtained after the expansion is more in line with reality.

[0082] Regarding the conditions for selecting coordinates, the conditions mean that the closest distance between the selected coordinates and the existing coordinates must be large enough to prevent the bird-repelling equipment from being too concentrated and affecting the bird-repelling effect.

[0083] As a preferred embodiment of the technical solution of the present invention, the step of creating a device matrix according to the device placement points, randomly selecting different numbers of row and column positions in the device matrix, and obtaining a test matrix set labeled by number includes:

[0084] Read the equipment placement points in the power grid area in sequence according to the preset order to create an equipment matrix;

[0085] Select the quantity in the range from one to the total number of devices;

[0086] After the number is selected, the number of row and column positions are randomly selected in the device matrix to obtain a test matrix, and the cycle is repeated for a preset number of times to obtain a test matrix of the number of cycles;

[0087] Take the selected number as label, count the test matrix and get the test matrix set.

[0088] By reading the device placement points in the order from north to south and from west to east (correspondingly from top to bottom and from left to right), a matrix can be created, called a device matrix. The number is determined incrementally in sequence. After the number is selected, the number of row and column positions are randomly selected in the device matrix to obtain a test matrix. The random selection process is repeated to obtain the number of test matrices of the cycle. The test matrices are counted with the number as labels to obtain a test matrix set.

[0089] Among them, the empty positions in the device matrix are filled with preset invalid data. When selecting row and column positions, the row and column positions corresponding to the invalid data are not selected. The meaning of this process is that the number of rows and columns of the device matrix is ​​fixed, but in actual scenarios, the actual number of each row and column is not necessarily the same. Therefore, there may be some row and column positions in the device matrix that do not have corresponding device placement points. At this time, the default invalid data is inserted.

[0090] As a preferred embodiment of the technical solution of the present invention, the step of collecting the bird-repelling utility values ​​corresponding to different test matrices according to a preset collection device and calculating the average bird-repelling utility values ​​of different quantities includes:

[0091] Establish a connection channel with the bird-repelling device based on the test matrix and send operating instructions;

[0092] The bird dispersal distance and effective duration are obtained according to the preset collection device; when the collection device is a camera, the bird dispersal distance is the maximum distance that the bird is away from the line, and the effective duration is the time difference between the time when the command is sent and the time when the bird appears on the line again;

[0093] The bird repellent utility value is calculated based on the bird repellent distance and effective duration;

[0094] Calculate the mean of the bird-repelling utility values ​​of all test matrices belonging to the same quantity to obtain the average bird-repelling utility value corresponding to the quantity.

[0095] The test matrix indicates which bird-repelling devices are selected. Based on the test matrix, a connection channel with the bird-repelling device is established, and an operating instruction is sent. Then, the bird dispersal distance and effective duration are obtained according to the preset collection device. The bird dispersal distance is how far the bird moves during each dispersal behavior. When the collection device is a camera, the bird and the line are located with the help of the target recognition algorithm, the distance between the bird and the line is calculated, and the maximum distance is selected as the bird dispersal distance (of course, the minimum distance can also be selected, which are two evaluation scales); the effective duration is the time difference between the time the instruction is sent and the time when the bird appears on the line again. In layman's terms, after a dispersal behavior, how long will it take for the bird to reappear? A comprehensive analysis is performed on the bird dispersal distance and the effective duration to obtain the bird repellent utility value. The longer the bird dispersal distance, the higher the bird repellent utility value, and the longer the effective duration, the higher the bird repellent utility value.

[0096] Finally, the mean of the bird-repelling utility values ​​of all test matrices belonging to the same number is calculated to obtain the average bird-repelling utility value corresponding to the number.

[0097] As a preferred embodiment of the technical solution of the present invention, the step of determining different numbers of selection probabilities according to the average bird-repelling utility value, and controlling the bird-repelling device based on the selection probability when receiving the bird-repelling instruction generated by the collection device includes:

[0098] Arrange the average bird-repelling utility values ​​in increasing order of quantity to obtain a utility value array;

[0099] Calculate the absolute value of the difference between adjacent data in the utility value array;

[0100] Determine the selection probability of each quantity based on the absolute value of the difference;

[0101] When the bird-repelling instruction generated by the collection device is received, the quantity is determined based on the selection probability, and the number of bird-repelling devices is randomly selected, a connection channel is established, and an operation instruction is sent.

[0102] Arrange the average bird-repelling utility values ​​in increasing order of quantity to obtain a utility value array, calculate the absolute values ​​of the differences between adjacent data in the utility value array, the larger the absolute value of the difference, the greater the effect that can be achieved when the quantity is increased by one; determine the selection probability of each quantity based on the absolute value of the difference and the quantity; after determining the selection probability of each quantity, when receiving the bird-repelling instruction generated by the acquisition device, determine the quantity based on the selection probability, and then randomly select the number of bird-repelling devices, establish a connection channel, and send the operation instruction.

[0103] For the selection probability of each quantity, the larger the quantity, the more bird-repellent equipment is used, the better the bird-repellent effect is, and the higher the cost is. The absolute value of the difference represents the effect gain that can be brought about by each increase in quantity. The greater the effect gain, the greater the selection probability of the increased quantity. The higher the quantity, the higher the cost and the smaller the selection probability.

[0104] Specifically, the process of determining the selection probability is as follows:

[0105] Where P j is the probability of selecting quantity j, |V j ―V j―1 | represents the absolute value of the difference corresponding to the number j; M is the total number of bird-repelling devices.

[0106] The significance of the process of determining the selection probability is that, for each quantity, the logarithm of the absolute value of the difference is calculated, one is added to make the logarithm greater than zero, and then divided by the quantity to obtain a parameter used to characterize whether each quantity is selected. Then, the parameter is normalized and converted into probability to obtain the selection probability. The reason for introducing the logarithm is that the influence of the absolute value of the difference on the selection probability is less than the influence of the quantity on the selection probability.

[0107] It is worth mentioning that the selection process of the equipment placement points in this application is random, the selected number of equipment placement points is random, and after the number is selected, the specific selection and activation process is also random. There are almost no rules, and it is difficult for birds to adapt, and the bird-repelling effect is excellent.
