Description

Multispectral all-weather coaxial real-time monitoring laser remote foreign matter removing system

Technical Field

The invention belongs to the technical field of laser photoelectron, and relates to a multispectral all-weather coaxial real-time monitoring remote laser foreign matter removing system.

Background

At present, in outdoor high-voltage line transmission, most lines are bare metal lines without insulation layer protection, and in order to ensure safety and stability and prevent short circuit and open circuit, no conductor can exist on the lines. However, foreign matters such as kites, various ropes, plastic bags, cloth strips and branches can easily fall on the lines, and once the objects are soaked by wind, frost, rain and snow, the dangers such as short circuit and grounding among metal lines are easily caused, so that tripping or line damage is caused. If the animal falls to a height that the animal can touch, the animal may be injured. Therefore, timely cleaning of foreign matters on the high-voltage line is very important for power supply safety.

The traditional method of clearing away circuit foreign matter at present adopts equipotential live working or the operation that cuts off the power supply, and the instrument of carrying or building the elevated platform will have the foreign matter of potential safety hazard to the wire to clear away. The traditional means generally has the defects of complex program, long operation time, high safety risk, large consumption of manpower and material resources and the like. Based on these problems, there is an urgent need to find new ways to work.

The method is characterized in that laser is emitted to the foreign matter on the ground, and the foreign matter is fused or fused through photothermal action, so that the purpose of removing the foreign matter is achieved in a non-contact mode. Compared with the traditional mode, the laser clearing technology is a safer and more convenient clearing mode.

Unlike the common laser remote clearing device, a multispectral all-weather laser remote clearing system capable of being monitored coaxially in real time is provided. The system has high-recognition aiming indicating light with red, green and blue spectrum colors, and adopts the indicating light with different color spectrums aiming at targets with different colors so as to prevent the indicating light from being submerged by the target background and being incapable of accurately aiming due to the fact that the indicating light has the same or similar color with the target background. In addition, the system has an infrared night vision function, and can monitor the target in real time under the condition of insufficient light at night or cloudy days and the like. In a real-time monitoring system, a high-precision camera light path and a laser beam are coaxial through a set of optical system, and a target is accurately positioned through indicating cross wires on a display screen, so that the target is accurately removed when the target is pointed.

The laser is powered by a power supply and is connected to the transmitting head through an optical fiber. The controller controls the spectrum conversion of the red, green and blue high-identification indicating lights and controls the laser energy adjustment and the laser emission. The emitted laser enters the coaxial optical system through the laser beam expanding lens and the laser collimating lens, and is reflected to a target through the two reflecting mirrors. Meanwhile, the high-definition camera collects images of objects to be removed through the coaxial optical system, realizes high-precision coaxiality with the laser beams, and monitors the images in real time through the displayer. Under the condition of insufficient light at night or in cloudy days and the like, the infrared night vision function of the high-definition camera system can be started to carry out all-weather monitoring.

Meanwhile, different from the conventional laser remote removal device, the high-identification aiming indicating light with the three spectral colors of red, green and blue is provided, and the indicating light with different color spectrums is adopted aiming at the targets with different colors, so that the condition that the indicating light is submerged by the target background and cannot be accurately aimed due to the fact that the color of the indicating light is the same as or similar to that of the target background is prevented. In addition, the system has an infrared night vision function, and can monitor the target in real time under the condition of insufficient light at night or cloudy days and the like.
