Gas detection system and method

Abstract

The invention discloses a gas detection system and method, and the structure of the gas detection system comprises a rainwater infiltration prevention multi-parameter gas detection device, an unmanned aerial vehicle connection end, a connection fixing block, a connection cable, a gas inlet, a connection positioning ring, and a fixed flitch plate. The rainwater infiltration prevention multi-parameter gas detection device is arranged at the left end of the unmanned aerial vehicle connection end and connected with the unmanned aerial vehicle connection end in a welded mode, the unmanned aerial vehicle connection end is arranged at the left end of the connection fixing block and connected with the connection fixing block in a fixedly-installed mode, and the connection cable penetrates through the center of the connection fixing block and is connected with the connection fixing block in a sealed mode. In the flying process of the unmanned aerial vehicle, in rainy days, a gas detection opening is of an automatic sealing structure, rainwater can be prevented from seeping into the gas detection device through the gas detection opening to damage the gas detection device, and meanwhile, a filtering grid is of a continuous vibration structure, and thus the blockage of the filtering grid caused by excessive solid particles is effectively prevented.

Description

[0001] This application is a divisional application with an application date of October 24, 2018 and an application number of CN201811243740.2, whose invention name is a multi-parameter gas detection device based on a drone. technical field [0002] The invention relates to the field of gas detection devices, more specifically, a gas detection system and method. Background technique [0003] At present, with the development of science and technology, drones have been used to detect air quality. This detection method has the characteristics of high detection accuracy and easy operation. However, the current gas detection device has the following disadvantages: [0004] 1. When the UAV is flying in the air to detect the air, when it encounters rainy weather, the rainwater will easily enter the gas detection device through the gas detection port, causing damage to the gas detection device. [0005] 2. At the same time, in the process of detecting gas, the gas detection device ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a gas detection system and method to solve the problem that the prior art unmanned aerial vehicles fly in the air to detect the air, when encountering rainy weather, rainwater is easy to pass through. The gas detection port enters the gas detection device, causing damage to the gas detection device. At the same time, during the gas detection process, the gas detection device will filter larger particles. Particulate matter, resulting in clogging of the filter mesh, affecting the gas detection work
