Problems solved by technology
However, in practical applications, in addition to removing foreign matter, the thermal effect of the laser may also damage other equipment on the overhead line, such as composite insulators
The existing laser obstacle removal equipment basically has no active safety protection measures for overhead line equipment. Generally, manual observation is used to avoid long-term laser irradiation equipment. This method has many uncontrollable factors (such as personnel misuse, personnel quality varies Qi), can not really avoid equipment damage

Embodiment
[0039] see figure 1 and figure 2 , in a preferred embodiment of the equipment safety protection method applied to the laser obstacle removal device of the present invention, the laser obstacle removal device 100 used includes a pan-tilt 101, a laser 102 and a camera 103; the laser 102 and the camera 103 are coaxial . The pan / tilt 101 can rotate independently of each other in the horizontal direction or the vertical direction, and also includes an encoder. The encoder is used to provide horizontal position information (azimuth angle) and vertical position information (elevation angle) of the pan / tilt 101 .
[0040] The pan / tilt 101 and the laser 102 are electrically connected to the control center 200 through data lines, and the control center 200 is used to realize power supply and data communication. The camera 103 uses the router 400 to communicate with the control center 200 through wired Ethernet. The mobile control platform 300 utilizes the router 400 to communicate ...

The invention relates to the fields of foreign matter removal of overhead transmission lines, cleaning of high-voltage transmission channels, power transmission and transformation technology, and in particular, an equipment safety protection method applied to a laser obstacle removal instrument. The laser obstacle remover used includes a pan / tilt, camera, laser, and the camera and laser are coaxial. The device safety protection method includes: after the laser obstacle removal device is turned on, the initial state information correction with the control center is completed; the user uses the mobile control platform to delineate the protection area of the laser obstacle removal device on the real-time image collected by the camera, and displays the corresponding protection area. The protection frame of the area. When the user performs an obstacle removal operation, the laser obstacle removal device synchronizes the status information to the mobile control platform. According to the state information, the mobile control platform controls the protection frame to move synchronously with the real-time image. When the pointing of the laser touches the edge of the protective frame, or enters the inner area of the protective frame, the laser will automatically stop output, thereby ensuring the safety of the equipment and environment in the protective frame and improving the efficiency of obstacle removal.
Description
technical field [0001] The invention relates to the fields of foreign matter removal of overhead transmission lines, cleaning of high-voltage transmission channels, power transmission and transformation technology, and in particular, an equipment safety protection method applied to a laser obstacle removal instrument. Background technique [0002] At present, the laser obstacle remover is widely used in foreign matter removal and tree obstacle removal of overhead lines in power systems. The laser obstacle remover uses the characteristics of strong laser directionality, high energy, and high efficiency of directional energy transmission to accurately launch the laser beam to the surface of foreign objects on overhead lines. Through the photothermal effect of the laser on the foreign matter, the foreign matter is heated to the vaporization or melting temperature. With the movement of the light beam, continuous slits are formed on the body of the foreign matter to cut off the ...
