Leaking natural gas distribution mapping system and method based on unmanned gyroplane

Abstract

The invention discloses a leaking natural gas distribution mapping system based on an unmanned gyroplane. A plated grillage, a flight control unit, a pan-tilt, a TDLAS methanol laser sensor and a wireless data transmission communication module are arranged in an unmanned gyroplane body; the flight control unit measures the position and the attitude of the unmanned gyroplane and executing an instruction from a ground station; the TDLAS methanol laser sensor realizes the scanning measurement action at a fixed cycle; the unmanned gyroplane acquire gas concentration integral data and record lightpath information at measurement point locations and transmits the data and the light path information to a ground PC terminal; the space area is divided into three-dimensional grids, and gas distribution mapping is performed on the three-dimensional space area with a computer aided tomography technology; filling is performed on gas concentration information of to-be-measured blind spots with a core extrapolation technology. The gas concentration information can be detected remotely and mapping can be performed on gas distribution states of three-dimensional environments.

Description

technical field [0001] The present invention relates to a system and method, and more specifically, relates to a system and method for mapping the distribution of natural gas leakage based on a rotary-wing unmanned aerial vehicle. Background technique [0002] With the steady progress of the construction of natural gas pipeline projects and the continuous improvement of the pipeline network, vicious accidents caused by sudden natural gas leakage occur frequently, causing heavy casualties and property losses, severely damaging the ecological environment, and even causing social panic and other problems. Therefore, the detection of natural gas leakage data is of great significance. [0003] Gas Distribution Mapping, as an important research direction of active olfaction of robots, is of great significance in environmental monitoring, gas leakage source location and disaster rescue. When a natural gas leakage accident occurs, the UAV can autonomously shuttle in the leakage are...

AI Technical Summary

Problems solved by technology

[0006] In summary, the existing natural gas pipeline inspection devices are difficult to obtain the gas concentration distribution in the leaking environment, and lack the ability to complete gas distribution mapping in three-dimensional space
