Problems solved by technology

The gas detection device is installed in the fire compartment in the channel, and it is connected to the comprehensive monitoring platform. The interaction between the detection data and the on-site staff is not timely, and the delay is relatively serious.
[0006] (3) The cost of configuring inspection robots is high
The inspection robot is installed in the channel to replace the manual detection of the gas content in the tunnel before the inspection operation. The installation and configuration of the inspection robot is expensive and does not have a large-scale promotion

Abstract

The invention discloses a cable tunnel environment detection system based on a multi-rotor unmanned aerial vehicle. The system comprises an unmanned aerial vehicle platform, a ground station and dataprocessing system, a cable fault detection system and a tunnel environment detection system, wherein the unmanned aerial vehicle platform is a carrying and moving platform of the whole system and moves up and down or left and right or is suspended according to a relevant instruction of the ground station and data processing system; and the tunnel environment detection system is also a task module,is fixed to the bottom of an unmanned aerial vehicle body through an unmanned aerial vehicle dedicated pod to be installed parallel to the fault detection system, is connected with an onboard communication unit in the unmanned aerial vehicle body through a USB interface, controls a sensor in the unmanned aerial vehicle body to detect air types and concentrations according to an instruction and transmits the air types and concentrations to ground staff. By using the system to carry out tunnel environment information detection, cable fault detection can be implemented at the same time, it is ensured that an internal cable runs in a suitable environment, cable disasters are reduced, the personal safety of the staff is benefited, inspection efficiency is improved, and intelligent power grid construction is promoted.

Description

technical field [0001] The invention belongs to the technical field of multi-rotor UAV technology and the detection technology of cable tunnel environment, and the specific content is a cable tunnel environment detection system based on multi-rotor UAV. Background technique [0002] With the rapid development of the national economy and urban construction, the demand for electricity continues to increase. The number of power cables in cities is also increasing, and the undergrounding of urban high-voltage power supply lines has become a trend. However, the power cable tunnel is a basically closed tunnel. During the operation of the cable, the aging of the internal insulation material will generate H 2 Toxic and harmful gases such as S and CO, CH 4 , NH 3 Such flammable and explosive gases and other harmful gases from the outside invade. The accumulation of these gases in the tunnel for a long time not only accelerates the aging of cables, but also easily leads to disaster...
