Description

Technical Field

[0001] The present invention relates to the field of transmission lines, and more specifically, to an airborne method for judging the voltage of a transmission line. Background Art

[0002] Before carrying out power outage maintenance operations, it is usually necessary to first check for electricity. Traditional electricity checking usually requires manual tower climbing operations. When checking for electricity, an electric checker is used to contact the power outage line or equipment. The longer the insulating rod used for higher voltage levels, the greater the operation difficulty. With the rapid development of unmanned aerial vehicles (UAVs), currently, a contact-type electric checker is mounted on the UAV and controlled by the staff on the ground, using the UAV to replace personnel climbing the tower to check for electricity. However, there are the following problems with mounting a contact-type electric checker on a UAV: (1) The GPS, IMU, and other positioning navigation and attitude sensing sensors of the UAV will be interfered by strong electromagnetic fields. Therefore, when the measured transmission line is energized, accidents such as crashing are extremely likely to occur; (2) Due to the small probe of the traditional contact-type electric checker, it is extremely difficult to make the contact head of the electric checker touch the measured wire when the wire sways due to air flow and there is wind deviation of the UAV. Summary of the Invention

[0003] In order to solve the above-mentioned existing technical problems, the present invention provides an airborne method for judging the voltage of a transmission line.

[0004] The technical solution adopted by the present invention is as follows:

[0005] An airborne method for judging the voltage of a transmission line, including the following specific steps:

[0006] S1. Deploy a connecting member to the UAV;

[0007] S2. Install an audible and visual electric checker;

[0008] S3. Move the metal probe on the audible and visual electric checker close to the transmission line to be detected, and use the handheld switch remote control to fix the metal probe on the transmission line to be detected;

[0009] S4. Lift the UAV and fly it above the transmission line, and observe through the video transmission system of the UAV whether the metal probe on the audible and visual electric checker hanging directly below the UAV touches the transmission line:

[0010] 1) If it is observed that the metal probe touches the transmission line, adjust the viewing angle of the UAV gimbal through the switch remote control to observe whether the sound alarm module on the audible and visual electric checker flashes to judge whether the transmission line is energized: If the sound alarm module flashes, it is judged that the transmission line is energized; otherwise, it is judged that the transmission line is not energized;

[0011] 2) If it is observed that the metal probe does not touch the transmission line, adjust the acoustic-optic voltage detector directly below the UAV through the switch remote controller until it is observed that the metal probe touches the transmission line, and then perform the judgment in step 1).

[0012] Further, the S1 specifically includes the following:

[0013] 1) Install an RTK module on the UAV;

[0014] 2) Set the connecting piece at the bottom of the UAV;

[0015] 3) Connect the connecting piece to the SDK development interface of the UAV, and the SDK development interface of the UAV is communicatively connected to the handheld switch remote controller;

[0016] 4) Wind the insulating rope around the motor arranged inside the connecting piece;

[0017] 5) Connect the remote control receiver arranged on the motor to the handheld switch remote controller communicatively;

[0018] 6) Control the up and down buttons in the handheld switch remote controller to adjust the telescopic length of the insulating rope.

[0019] Further, the S2 specifically includes the following:

[0020] 1) Bind the acoustic-optic voltage detector to the other end of the insulating rope;

[0021] 2) Connect the metal probe directly below the acoustic-optic voltage detector to the handheld switch remote controller communicatively; wherein, the metal probe is arranged in an openable and closable ring shape.

[0022] Further, the S3 specifically includes the following:

[0023] 1) The handheld switch remote controller emits a remote control signal;

[0024] 2) The receiving module on the acoustic-optic voltage detector captures the remote control signal, converts it into an electrical signal and transmits it to the control module on the acoustic-optic voltage detector;

[0025] 3) The control module controls the opening and closing of the metal probe and fixes the metal probe to the transmission line to be detected.

[0026] The present invention has the following beneficial effects compared with the prior art:

[0027] 1) Install an RTK module on the UAV to avoid the situation that the attitude of the UAV is unstable or even crashes due to strong electromagnetic field interference;

[0028] 2) Set the remote control receiver and the hand-controlled remote controller. When the operator clicks the up and down buttons in the hand-controlled remote controller, the insulating rope can be telescoped, thereby controlling the length of the insulating rope;

[0029] 3) The metal probe is set to be an open and closed ring to achieve all-round wrapping of the power transmission line to be detected, enhance the detection stability, and avoid affecting the contact between the metal probe and the power transmission line to be detected when the wire sways due to air flow and the drone has wind drift.

[0030] 4) When the wind speed at the operation site is too high and affects the hovering stability of the unmanned aerial vehicle, the opening and closing of the ring-shaped metal probe are controlled by using a handheld switch remote controller, and then the metal probe is fixed or moved to the power transmission line to be detected, which is convenient and fast.

[0031] 5) The viewing angle of the drone gimbal is adjusted through the switch remote controller to observe whether the light signal of the acoustic-optical voltage detector flashes to determine whether the power transmission line is energized. It does not require multiple people to operate, improving the detection efficiency and saving costs. BRIEF DESCRIPTION OF THE DRAWINGS
