Description

Technical Field

[0001] The invention relates to the field of electric power facilities, and in particular to a fixed pull rope detection system for an insulating hard ladder equipped with a power supply network line. Background Art

[0002] As one of the commonly used power facilities, the insulated rigid ladder is a live working tool when used in live working scenarios. In other scenarios, such as substation maintenance, line climbing, meter reading, etc., the insulated rigid ladder is a safety tool. As a supporting facility for the insulated rigid ladder, the fixed pull rope of the insulated rigid ladder should have a physical distance less than or equal to the set distance threshold to ensure the safety protection effect of the insulated rigid ladder, so that the fixed pull rope installed on the insulated rigid ladder can achieve the expected stability effect on the insulated rigid ladder.

[0003] However, the prior art lacks a customized, high-precision detection mechanism for the physical distance between the fixed pull rope of the insulating rigid ladder and the insulating rigid ladder, which makes it difficult to judge whether the fixed pull rope installed on the insulating rigid ladder can achieve the expected stabilizing effect on the insulating rigid ladder. Summary of the invention

[0004] In order to solve the technical problems in the related fields, the present invention provides a fixed pull rope detection system for an insulated rigid ladder installed in a power supply network line, which can quote an artificial intelligence model to intelligently identify the physical distance between the insulated rigid ladder and the fixed pull rope based on the coordinate values ​​of each pixel point in a first detection area, the coordinate values ​​of each pixel point in a second detection area, the curve length of the edge of the first detection area, the curve length of the edge of the second detection area, the depth of field value of each pixel point in the first detection area, and the depth of field value of each pixel point in the second detection area. The intelligent identification of the physical distance between the insulated rigid ladder and the fixed pull rope is triggered only when the insulated rigid ladder is in an unfolded state. When the physical distance between the insulated rigid ladder and the fixed pull rope obtained by the intelligent identification is greater than the set distance threshold, an alarm processing is performed that the fixed pull rope is too far away from the insulated rigid ladder, so as to ensure that the installed fixed pull rope can achieve the expected stabilization effect on the insulated rigid ladder.

[0005] According to the present invention, a fixed pull rope detection system for an insulated rigid ladder equipped with a power supply network line is provided, the system comprising:

[0006] A state analysis mechanism connected to an insulating hard ladder for a power supply network line, for issuing a first analysis command when the insulating hard ladder is in an extended state, and for issuing a second analysis command when the insulating hard ladder is not in an extended state;

[0007] A visualization imager connected to the state analysis mechanism, and configured to perform a visualization imaging operation on the wiring scene of the power supply network line upon receiving the first analysis command, so as to obtain and output a corresponding wiring scene image;

[0008] A sequential conversion mechanism, connected to the visualization imager and comprising a content enhancement device, a directional blurring device and a real-time filtering device, for sequentially performing image content enhancement processing based on logarithmic transformation, directional blurring processing and Gaussian high-pass filtering processing on the received wiring scene image, so as to obtain and output a corresponding sequential conversion image;

[0009] A first analysis device is connected to the sequential conversion mechanism, and is used to detect an imaging area of ​​the insulating hard ladder in the sequential conversion image as a first detection area based on the brightness imaging characteristics of the insulating hard ladder, and to detect an imaging area of ​​the fixed rope in the sequential conversion image as a second detection area based on the brightness imaging characteristics of the fixed rope;

[0010] a second analysis device, connected to the first analysis device, for intelligently identifying the physical distance between the insulating rigid ladder and the fixed pull rope based on the coordinate values ​​of each pixel point in the first detection area, the coordinate values ​​of each pixel point in the second detection area, the curve length of the edge of the first detection area, the curve length of the edge of the second detection area, the depth of field value of each pixel point in the first detection area, and the depth of field value of each pixel point in the second detection area by referencing the artificial intelligence model;

[0011] An instant alarm device, connected to the second analysis device, is used to execute an alarm process that the fixed pull rope is too far away from the insulating hard ladder when the physical distance between the intelligently identified insulating hard ladder and the fixed pull rope is greater than a set distance threshold;

[0012] Among them, the artificial intelligence model is referenced to intelligently identify the physical distance between the insulated rigid ladder and the fixed pull rope based on the coordinate values ​​of each pixel point in the first detection area, the coordinate values ​​of each pixel point in the second detection area, the curve length of the edge of the first detection area, the curve length of the edge of the second detection area, the depth of field value of each pixel point in the first detection area and the depth of field value of each pixel point in the second detection area, including: the artificial intelligence model is a feedforward neural network after executing a set number of trainings, and the value of the set number is proportional to the product of the length and width of the sequential transformation image.

[0013] It can be seen that the present invention mainly has the following significant technical effects:

[0014] First, based on the brightness imaging feature of the insulating hard ladder, an imaging area of ​​the insulating hard ladder in the sequential conversion image is detected as a first detection area, and based on the brightness imaging feature of the fixed rope, an imaging area of ​​the fixed rope in the sequential conversion image is detected as a second detection area;

[0015] Second, the artificial intelligence model is used to intelligently identify the physical distance between the insulated rigid ladder and the fixed pull rope based on the coordinate values ​​of each pixel point in the first detection area, the coordinate values ​​of each pixel point in the second detection area, the curve length of the edge of the first detection area, the curve length of the edge of the second detection area, the depth of field value of each pixel point in the first detection area, and the depth of field value of each pixel point in the second detection area;

[0016] Third: Only when the insulating rigid ladder is in the unfolded state, the intelligent identification of the physical distance between the insulating rigid ladder and the fixed pull rope is triggered, and when the physical distance between the insulating rigid ladder and the fixed pull rope obtained by the intelligent identification is greater than the set distance threshold, the alarm processing of the fixed pull rope being too far away from the insulating rigid ladder is executed to ensure that the installed fixed pull rope can achieve the expected stabilizing effect on the insulating rigid ladder.

[0017] The fixed pull rope detection system for the insulating hard ladder installed with the power supply network line of the present invention has a simple structure and is easy to operate. Since it can refer to the artificial intelligence model to intelligently identify the physical distance between the insulating hard ladder and the fixed pull rope based on various visual data, and when the physical distance between the insulating hard ladder and the fixed pull rope exceeds the limit, an alarm processing is executed that the fixed pull rope is too far away from the insulating hard ladder, thereby ensuring that the installed fixed pull rope can achieve the expected stabilization effect on the insulating hard ladder.
