Automatic monitoring system for tunnel gas based on unmanned plane platform and method thereof

Abstract

The invention discloses an automatic monitoring system for tunnel gas based on an unmanned plane platform and a method thereof. The explosion-proof unmanned plane platform comprises an unmanned planeand a remote monitoring platform; a flight driving unit uses a danger distance perceiving module to realize safe flight of a unmanned plane, the unmanned plane can fly forward in the tunnel under safedistance condition and accurately arrives a to-be-monitored position, and an automatic monitoring unit uses a gas concentration perceiving module and an image acquisition module arranged at the unmanned plane to realize monitoring on the gas concentration in the tunnel and shooting on the images in the tunnel, the collected data is transmitted to a remote monitoring platform through a wireless signal transmission unit; the remote monitoring platform controls a running state of the unmanned plane, the collected data is processed, the collected image is identified, and alarming is carried out when the monitoring data is abnormal. The provided technical scheme can increase the monitoring precision and efficiency, and greatly increases the monitoring security.

Description

technical field [0001] The invention relates to the technical field of automatic monitoring of gas concentration in tunnels, in particular to a system and method for automatic monitoring of gas in tunnels based on an explosion-proof UAV platform. Background technique [0002] At present, the construction of highways and railways has set off a new construction climax in the western mountainous areas. Many of these projects have adopted the tunnel scheme, but it is more common to pass through coal-measure areas with weak lithology and high-pressure coal seam gas tunnels. Therefore, the adverse effects of gas must be considered during tunnel construction. [0003] Generally speaking, the probability of gas disaster accidents in tunnels is very small, but once a gas explosion or gas outburst accident occurs, the consequences are often very serious, which will cause great loss of life and property and extremely bad social impact. In recent years, with the continuous increase of...

Problems solved by technology

However, there are some difficulties and potential risks in the manual detection process using portable gas detectors

One is that gas monitors need to hold portable tile detectors and can only perform detection in a limited space. Due to height restrictions, there are some dead spots that cannot be detected

Second, in the process of "one shot and three inspections", especially after the shot was fired on the face of the pit, there is a waste residue area of ​​more than ten meters in front of Xincheng's face. To complete the gas concentration detection on the face of the face, the gas monitor must climb Walking through the waste to reach the hand is very inconvenient and a safety risk

[0005] In addition, due to the instability of the surrounding rock, the gas monitors approaching the face of the tunnel rashly will cause great danger to their lives, which is not conducive to accurately detecting the gas concentration of the section vault

There are also shortcomings in the traditional automatic gas monitoring system. First, the high-precision gas concentration sensor in the automatic gas monitoring system is relatively fixed and lacks flexibility. Real-time monitoring

Second, its feedback system is relatively simple and cannot effectively provide timely and valuable reference and countermeasures

[0006] Missed or false detection of gas concentration caused by the above problems may become a hidden danger of gas accidents
