Abstract

The invention relates to an intelligent state analysis system for a high-voltage transmission line. The system comprises a content analysis device which is used for sending a rope body falling-off signal when the total number of pixel points occupied by both a closed image area where an operator is located and a closed image area where a lead anti-falling protection rope is located in a primary enhanced picture is lower than a limit; and the dynamic display device is used for taking a line identifier corresponding to a part of the line of the high-voltage transmission line where the directional acquisition mechanism is located as a high-risk working state line and performing highlight red display when receiving the rope body falling-off signal.

Description

Technical Field

[0001] The present invention relates to the field of high-voltage transmission lines, and more specifically, to an intelligent state analysis system for high-voltage transmission lines. Background Art

[0002] Generally speaking, high voltage transmission lines can be divided into cable transmission lines and overhead transmission lines, among which overhead transmission lines are the most common.

[0003] Cable transmission line: The cable is buried underground, which does not take up space, but is inconvenient to construct and maintain. It is mostly used in cities and across river lines.

[0004] Overhead transmission lines: Use transmission towers to suspend conductors and ground wires in the air, so that a certain safe distance is maintained between conductors, between conductors and ground wires, between conductors and towers, and between conductors and ground obstacles to complete the transmission task.

[0005] Currently, when performing safety management on high-voltage transmission lines, it is impossible to detect the relative distribution status of each operator and the conductor anti-detachment protection rope to perform a hazard assessment of whether the conductor anti-detachment protection rope has fallen off the operator, resulting in the inability to ensure the operation safety of the high-voltage transmission lines. Summary of the invention

[0006] In order to solve the technical problems in the related fields, the present invention provides an intelligent state analysis system for high-voltage transmission lines. When there are operating personnel in the preview picture of the line environment corresponding to the high-voltage transmission line directionally collected by the directional collection mechanism, the system performs a real-shot operation on the line environment corresponding to the high-voltage transmission line to obtain a real-shot picture of the environment, thereby taking into account both the monitoring effect and power consumption saving. The received real-shot picture of the environment is successively processed based on nonlinear grayscale transformation, arithmetic mean filtering and artifact elimination to obtain and output a secondary enhancement machine picture with better image quality, so as to provide more reliable basic data for the relative distribution state of subsequent operating personnel and wire anti-detachment protection ropes to perform intelligent judgment on whether the wire anti-detachment protection rope has fallen off the operating personnel, as well as in the closed image area where the operating personnel are located and the closed image area where the wire anti-detachment protection rope is located. When the total number of pixel points jointly occupied by the image area in the primary enhanced picture is greater than the cumulative value of the total number of pixel points occupied by the closed image area where the operating personnel are located in the primary enhanced picture alone and the total number of pixel points occupied by the closed image area where the conductor anti-detachment protection rope is located in the primary enhanced picture alone, a rope body has not fallen off signal is issued; otherwise, a rope body has fallen off signal is issued. A dynamic display device is also introduced and arranged in a monitoring room near the directional acquisition mechanism. When a rope body has fallen off signal is received, the line identifier corresponding to the part of the high-voltage transmission line where the directional acquisition mechanism is located is used as a high-risk working state line and is displayed in high-brightness red; and when a rope body has not fallen off signal is received, the line identifier corresponding to the part of the high-voltage transmission line where the directional acquisition mechanism is located is used as a low-risk working state line and is displayed in low-brightness blue.

[0007] According to the present invention, there is provided a high-voltage transmission line intelligent state analysis system, the system comprising: A directional acquisition mechanism, for performing a real-time shooting operation of the line environment corresponding to the high-voltage transmission line when there are operating personnel in the preview picture of the line environment corresponding to the directional acquisition of the high-voltage transmission line, so as to obtain a real-time shooting picture of the environment; A primary enhancement mechanism, connected to the directional acquisition mechanism, is used to perform nonlinear grayscale transformation processing on the received real-life environmental image to obtain and output a corresponding primary enhanced image; A secondary enhancement mechanism, connected to the primary enhancement mechanism, is used to successively perform arithmetic mean filtering processing and artifact elimination processing on the received primary enhancement picture to obtain and output a corresponding secondary enhancement machine picture; A region identification device is connected to the secondary enhancement mechanism and is used to identify the closed image region where the operator is located based on the brightness imaging characteristics of the operator in the received primary enhancement picture, and to identify the closed image region where the wire anti-detachment protection rope is located based on the brightness imaging characteristics of the wire anti-detachment protection rope in the received primary enhancement picture; a content analysis device connected to the area identification device, and configured to send a rope-falling signal when the total number of pixels occupied by the closed image area where the operator is located and the closed image area where the wire anti-falling protection rope is located in the primary enhanced picture is less than or equal to the cumulative value of the total number of pixels occupied by the closed image area where the operator is located in the primary enhanced picture alone and the total number of pixels occupied by the closed image area where the wire anti-falling protection rope is located in the primary enhanced picture alone; A dynamic display device is arranged in a monitoring room near the directional acquisition mechanism and is wirelessly connected to the content analysis device, and is used to, upon receiving a rope falling signal, mark the line identifier corresponding to a part of the high-voltage transmission line where the directional acquisition mechanism is located as a high-risk working state line and display it in bright red; The content analysis device is further used to send a rope body not falling off signal when the total number of pixel points occupied by the closed image area where the operator is located and the closed image area where the wire anti-falling protection rope is located in the primary enhanced picture is greater than the cumulative value of the total number of pixel points occupied by the closed image area where the operator is located in the primary enhanced picture alone and the total number of pixel points occupied by the closed image area where the wire anti-falling protection rope is located in the primary enhanced picture alone; Wherein, the dynamic display device is also used to, when receiving a signal that the rope has not fallen off, display the line identifier corresponding to the part of the high-voltage transmission line where the directional collection mechanism is located as a low-risk working state line and display it in low-brightness blue.

[0008] It can be seen that the present invention has at least the following significant technical advances: First, when there are operators in the preview image of the line environment corresponding to the high-voltage transmission line collected by the directional collection mechanism, a real-time shooting operation of the line environment corresponding to the high-voltage transmission line is performed to obtain a real-time shooting image of the environment, thereby taking into account both monitoring effect and power consumption saving; Second: the received real-life environmental images are processed based on nonlinear grayscale transformation, arithmetic mean filtering and artifact elimination to obtain and output a secondary enhancement machine image with better image quality, providing more reliable basic data for the subsequent relative distribution of operators and wire anti-slip protection ropes to perform intelligent judgment on whether the wire anti-slip protection rope has fallen off the operator; Third: when the total number of pixels occupied by the closed image area where the operator is located and the closed image area where the wire anti-falling protection rope is located in the primary enhanced picture is greater than the cumulative value of the total number of pixels occupied by the closed image area where the operator is located in the primary enhanced picture alone and the total number of pixels occupied by the closed image area where the wire anti-falling protection rope is located in the primary enhanced picture alone, a rope body not falling off signal is issued, otherwise, a rope body falling off signal is issued; Fourthly: a dynamic display device is introduced and arranged in a monitoring room near the directional acquisition mechanism, which is used to, when receiving a rope detachment signal, mark the line mark corresponding to the part of the high-voltage transmission line where the directional acquisition mechanism is located as a high-risk working state line and display it in highlighted red; and, when receiving a rope non-detachment signal, mark the line mark corresponding to the part of the high-voltage transmission line where the directional acquisition mechanism is located as a low-risk working state line and display it in low-brightness blue.

[0009] The intelligent state analysis system for high-voltage power transmission lines of the present invention has a compact structure and intelligent control. When there are operators in the preview screen of the line environment corresponding to the high-voltage power transmission line collected by the directional collection mechanism, the relative distribution state of the operators and the conductor anti-falling protection rope is detected to perform the danger identification of whether the conductor anti-falling protection rope falls off the operators, thereby improving the intelligent level of high-voltage power transmission line management.
