Problems solved by technology

[0003] At present, most of the inspection methods commonly used for transmission lines are manual inspection, and some transmission systems use helicopter inspection. However, due to geographical and climatic conditions, and the inspection cost is high, there are great safety hazards in urban inspection.
However, robot line inspection has the defects of immature technology and high failure rate
For urban power transmission lines, manual inspection is still commonly used at present. If conventional methods such as naked eyes and telescopes are used to inspect the line, the inspection accuracy is low, labor-intensive, and the probability of missed detection is high.

Abstract

The invention discloses a transmission line patrol system based on optical transmission. The transmission line patrol system comprises an on-pole device and a vehicle-mounted device. The on-pole device is arranged on a line pole tower and used for acquiring data of the temperature, images and the environment of a line and the line pole tower. The vehicle-mounted device is arranged on a line patrol vehicle and used for receiving data information acquired by the on-pole device and supplying energy to the on-pole device through lasers. The on-pole device sends the acquired data information to the vehicle-mounted device in a wireless optical communication mode, and the vehicle-mounted device transmits the received data information to a processing terminal for processing. Through laser energy supply and optical communication, electromagnetic interference is greatly reduced, battery energy supply is not needed, electricity does not need to be taken from the transmission line, and therefore the system is not in electrical connection with equipment on the detected line; the system is safer and more reliable, the cycle of overhaul and maintenance can be greatly prolonged, and signal confidentiality is high.

Description

technical field [0001] The invention relates to the technical field of power transmission line monitoring, in particular to a power transmission line inspection system based on optical transmission. Background technique [0002] With the development of society, the scale of cities is increasing day by day, and the electricity consumption capacity is constantly increasing. The voltage level of the urban power supply network is constantly increasing. However, with the gradual increase in the density of transmission corridors, higher and higher requirements are put forward for the safety and reliability of transmission lines. Therefore, the inspection of lines becomes particularly important. . [0003] At present, most of the inspection methods commonly used for transmission lines are manual inspection, and some transmission systems use helicopter inspection. However, due to geographical and climatic conditions, and the inspection cost is high, there are great safety hazards i...
