The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for checking a state of a protection pressing plate of a substation according to an embodiment of the present invention, where this embodiment is applicable to a situation in which a trip state of the protection pressing plate is checked in the substation, and the method may be executed by a device for checking a state of the protection pressing plate of the substation, and specifically includes the following steps:
and 110, acquiring initial image data of the transformer substation protection pressing plate.
In an electric power system, a protection pressure plate is also called a protection connecting sheet or a trip pressure plate, is a bridge and a link of a protection device which are connected with external wiring, and is related to the function of protection and whether an action outlet can normally play a role. The state of the protective pressing plate mainly comprises a throwing state and a withdrawing state, namely the protective pressing plate is in the throwing state and the withdrawing state, which shows that the protective pressing plate is in different positions.
In a specific implementation, the acquisition mode of the initial image data of the substation protection pressing plate can be various. For example, the transformer substation protection pressing plate can be shot and obtained through an operator through portable equipment, so that initial image data containing the transformer substation protection pressing plate is obtained. Or, an image acquisition device is arranged at a fixed point corresponding to the transformer substation protection pressing plate, and the transformer substation protection pressing plate is shot at fixed time to acquire image data containing the transformer substation protection pressing plate as initial image data. In addition, other types of acquisition modes for acquiring the initial image data of the substation protection pressure plate in the embodiment of the present invention may also be adopted, which are not listed in detail herein.
In addition, the initial image data in the embodiment of the present invention is not limited to the case of only including a single substation protection pressing plate, but also includes the case of simultaneously including a plurality of substation protection pressing plates, that is, the initial image data in the embodiment of the present invention may be image data of a single substation protection pressing plate, or image data of a plurality of substation protection pressing plates, and the number of the substation protection pressing plates is not limited in the present invention. When the image data of the plurality of transformer substation protection pressing plates are collected, the image data of the plurality of transformer substation protection pressing plates can be sequenced according to the rule of collection time and the like, so that the initial image data comprises the image data of the plurality of transformer substation protection pressing plates.
And step 120, performing image enhancement processing and image morphology processing on the initial image data to obtain target image data.
For the initial image data, the image information and the background image information of the transformer substation protection pressing plate are included, the difference between the transformer substation protection pressing plate and the background image can be enhanced by performing image enhancement processing and image morphology processing on the initial image data, and the transformer substation protection pressing plate can be better identified from the initial image data.
In the embodiment of the invention, the image enhancement processing on the initial image data is purposefully enhanced to the image data of the transformer substation protection pressing plate in the initial image data, so that the recognizable effect of the transformer substation protection pressing plate is enhanced. The image morphology processing of the initial image data is to further reduce the influence of the image data of the background part in the initial image data on the subsequent recognition process and reduce the interference elements in the recognition process on the basis of the image enhancement processing.
And step 130, classifying the target image data by using a classifier to obtain state information of the transformer substation protection pressing plate, wherein the state information comprises a label and a switch state of the transformer substation protection pressing plate.
By applying the embodiment of the invention, the target image data can be classified by utilizing the pre-trained classifier, so that the position state of the substation protection pressing plate corresponding to the target image data and the label of the substation protection pressing plate are determined. The position state and the work of the substation protection pressing plate are opposite to each other, namely the substation protection pressing plate is in different positions and has different switching states, for example, the substation protection pressing plate is in a switching state when the substation protection pressing plate is in a closed position, and the substation protection pressing plate is in a switching-out state when the substation protection pressing plate is in an open position. In addition, the label can be information marked on the transformer substation protection pressing plate such as the number and the model of the transformer substation protection pressing plate and is used for representing the information of the transformer substation protection pressing plate.
And 140, when the state information is different from a preset state threshold value of the transformer substation protection pressing plate, sending an abnormal signal.
After the switching state of the transformer substation protection pressing plate is determined by classification through the classifier, whether the switching state of the transformer substation protection pressing plate is consistent with a preset state threshold value of the transformer substation protection pressing plate can be judged according to comparison, and therefore whether the switching state of the transformer substation protection pressing plate meets the safe operation requirement of equipment is judged.
The technical scheme of the embodiment collects the initial image data of the transformer substation protection pressure plate, then carries out image enhancement processing and image morphology processing on the initial image data, can effectively reduce the identification degree of the transformer substation protection pressing plate and the background in the initial image data of the transformer substation protection pressing plate, reduce the interference when the subsequent classifier is classified, improve the classification accuracy of the classifier on the initial image data of the transformer substation protection pressing plate, reduce the calculated amount of the classifier, by comparing the on-off state of the substation protection pressing plate classified by the classifier with a preset state threshold value, whether the transformer substation protection pressing plate is in the required switching state or not can be effectively judged, the workload of checking the switching state of the transformer substation protection pressing plate by the participation of operating personnel is reduced, omission caused by people or misjudgment is reduced, and the operation safety of a power grid is improved.
Example two
Fig. 2 is a flowchart of a method for checking a state of a protection pressing plate of a substation according to a second embodiment of the present invention. The embodiment is a refinement based on the first embodiment, and describes in detail a process of processing initial image data of a substation protection pressure plate. The method specifically comprises the following steps:
step 201, continuously collecting image information of a plurality of transformer substation protection pressing plates.
Step 202, sequencing the image information according to the acquisition sequence to obtain initial image data.
In specific implementation, for initial image data of the substation protection pressing plate, it is not limited to acquiring image information of a single substation protection pressing plate as the initial image data required in the embodiment of the present invention, and image information of a plurality of substation protection pressing plates may be simultaneously acquired according to actual requirements to form a matrix as the initial image data.
Step 203, graying the initial image data.
In the embodiment of the invention, the gray processing is performed on the initial image data, and the gray processing is to convert the RGB color values of the pixel points in the initial image data into gray values through a specified calculation rule, and the gray values are used for representing the substation protection pressing plate. Wherein the specified calculation rule may be: 1. the component method comprises the steps of selecting one of RGB components as a gray value; 2. the maximum value method, which takes the maximum value of the three-component brightness in the color image as the gray value of the gray image; 3. the average value method is used for averaging the three-component brightness in the color image to obtain a gray value; 4. the weighted average method carries out weighted average on the three components according to different weights according to importance and other indexes.
And step 204, carrying out binarization and corrosion processing on the initial image data.
Image Binarization (Image Binarization) is a process of setting the gray value of a pixel point on initial Image data after gray processing to be 0 or 255, namely, enabling the whole Image to show an obvious black-and-white effect. The 256 brightness level gray scale image is selected by proper threshold value to obtain the binary image which can still reflect the whole and local features of the image.
The corrosion treatment is to reduce and refine the highlight area or white part in the binary image obtained after the binary treatment, and the operation result graph is smaller than the highlight area of the original image so as to reduce noise points and enable the processed image to have higher identification degree.
Wherein the etching process in step 204 comprises:
scanning each pixel in the initial image data by using the structural element, and enabling the structural element and the value of the pixel covered by the structural element to execute logic AND operation;
if all the results obtained after the logical and operation are 1, the pixel value of the pixel in the initial image data after the etching processing is 1, otherwise, the pixel value is 0.
And step 205, inputting the target image data into a pre-trained classifier to obtain the label and the switch state of the transformer substation protection pressing plate.
In the embodiment of the invention, the classifier is used for dividing the initial image data subjected to graying, binarization and corrosion treatment into the input state and the exit state according to the input and exit states of the protection pressing plate of the transformer substation, and then identifying the label content corresponding to the protection pressing plate of the transformer substation in the initial image data, so that the label content corresponding to the protection pressing plate of the transformer substation is obtained from the initial image data, and the identification of the protection pressing plate of the transformer substation is conveniently realized.
And step 206, forming a target matrix by the label and the switch state as the state information of the transformer substation protection pressing plate.
In the embodiment of the invention, after the classification by the classifier, the labels of the transformer substation protection pressure plate in the initial image data are associated with the on-off state of the transformer substation protection pressure plate, the rows of the target matrix are divided according to the number of the labels in the initial image data, and the labels and the corresponding state information are respectively filled in different columns of the corresponding rows, so that the target matrix in the embodiment of the invention is formed. And the switching state of the substation protection pressing plate is represented by 0 and 1, so that a value corresponding to the substation protection pressing plate in the target matrix is formed.
And step 207, acquiring a state threshold corresponding to the substation protection pressing plate.
In the specific implementation, the switching state of each substation protection pressing plate of the substation is specified, namely, the substation protection pressing plate is specified to be in a switching state or a switching-out state during normal operation. Before checking the switching state of the transformer substation protection pressing plate, a corresponding table of a label and a preset state, namely the state threshold value in the embodiment of the invention, is set according to the switching state requirement of the transformer substation protection pressing plate.
Step 208, comparing the state information with a state threshold value;
if the status information is different from the status threshold, go to step 209;
step 209, send out abnormal signal.
In the embodiment of the invention, the switching state of the substation protection pressing plate identified after classification by the classifier and the target matrix formed by the labels are compared with the preset state threshold value, whether the switching state of the substation protection pressing plate is normal or not can be determined, and the abnormal information is sent out after the switching state is judged to be abnormal, so that the switching state of the substation protection pressing plate corresponding to an operator is informed to be in the abnormal state, and the operator further checks the switching state, thereby effectively reducing the workload of the operator.
