Wireless audio and video transmission system for transmission line helicopter routing inspection

Abstract

The invention discloses a wireless audio and video transmission system for transmission line helicopter routing inspection. The system comprises a helicopter airborne system, a ground station system and a command center end system, wherein the helicopter airborne system is connected with the ground station system in a wireless communication way; the ground station system is connected with the command center end system in an industrial Ethernet way; the helicopter airborne system further comprises a front end video acquisition and storage system, a video transmission system and a voice intercom system; the ground station system further comprises an audio and video receiving system, a local video monitoring system, a VOIP telephone system and an optical fiber transmission system; and the command center end system further comprises a video playing system, a picture recording system and a VOIP telephone system. Due to the adoption of the technical scheme, the system not only can change and improve the conventional line walking mode and work efficiency, but also can achieve real-time multi-channel video transmission, storage and voice intercom.

Description

technical field [0001] The invention relates to the technical field of power transmission line patrol inspection, in particular to a wireless audio and video transmission system for power transmission line helicopter patrol inspection. Background technique [0002] The current conventional manual line inspection operation method of construction, inspection, overhaul and maintenance of transmission lines in our country is not only labor-intensive, working conditions are difficult, but also labor efficiency is low. Especially in the event of power grid emergency failures and abnormal weather conditions, line maintenance personnel have to rely on ground transportation or walking on foot, use ordinary instruments or the naked eye to inspect facilities and deal with equipment defects, which can no longer fully adapt to modern times. [0003] In the future, the ultra-high voltage and ultra-high voltage transmission lines to be built in my country's power grid projects will cover t...

Problems solved by technology

[0009] 1. In the current manned-machine line inspection system, inspection images can only be videotaped and sent back to the headquarters for playback and analysis by experts. Remote real-time monitoring and dispatching command cannot be achieved. The disadvantages are particularly significant in emergency disaster inspections

[0010] 2. In the current UAV line inspection system, the microwave transmission distance is short, and the diffraction ability and transmission distance of 2.4G or 5.8G microwave in wireless transmission are very short, so that the UAV cannot fly during the line inspection. Too far away from the ground station, which limits the radius of line patrol operations
