Problems solved by technology

[0003] With the advancement of rural urbanization in China, the construction of high-rise buildings is speeding up, but the equipment for fire alarms in high-rise buildings is relatively backward
At the same time, with the progress of industrial production, it is easy to cause various fire hazards. Among them, the fire safety hazards caused by explosions in chemical plants are particularly obvious. Once released into the air, these gases will not only affect the nearby residents, but also pose a serious threat to the life safety of firefighters in the fire rescue.
[0004] However, the unmanned aerial vehicle in the related art lacks further monitoring of the gas conditions in the fire environment. Therefore, there is an urgent need for an unmanned aerial vehicle that can detect the air quality of the fire scene in high altitude in time to help firefighters eliminate potential risks

experiment example

[0031] The gas sensor using nano-polyaniline-activated carbon as the coating of the gas-sensing material was tested against four gases: ethanol, acetone, acetaldehyde and dibutyl phthalate, and the response speed and performance of the gas sensor to different gases were evaluated. Limit concentration, and then evaluate the size of the detection domain of a high-altitude fire alarm drone for real-time monitoring of harmful gases provided by the embodiment of the present invention. The comparison between the data transmitted by the UAV and the data collected by HPLC in the laboratory is shown in Table 1 below:

Abstract

The invention discloses a high-altitude fire warning unmanned aerial vehicle capable of monitoring harmful gas in real time. The high-altitude fire warning unmanned aerial vehicle comprises an unmanned aerial vehicle body, a sensor support, a camera and an ejection pipeline, the camera and the sensor support are arranged on one side of the unmanned aerial vehicle body closely, orientation of the ejection pipeline is same as that of the camera and the sensor support, the ejection pipeline comprises a nozzle with orientation same as that of the camera and the sensor support and a pipeline connected with the nozzle, the pipeline can be used for connecting a water pipe or fire extinguishing powder, the sensor support is arranged above the camera, the sensor support is provided with multiple cells for placement of sensors different in type, and a gas-sensitive sensor for sensing gas type is placed in one cell. By mounting the camera and the sensors, fire disaster condition can be explored in real time, so that convenience is brought to working personnel to accurately and effectively perform fire disaster rescue, fire extinguishing efficiency is improved greatly, and life safety of firefighting personnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a high-altitude fire alarm drone for real-time monitoring of harmful gases. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. [0003] With the advancement of urbanization in China's rural areas, the construction of high-rise buildings has accelerated, but the equipment for fire protection and fire alarms in high-rise buildings is relatively backward. At the same time, with the progress of industrial production, it is easy to cause various fire hazards. Among them, the fire safety hazards caused by explosions in chemical plants are particularly obvious. Once these gases are released into the air, they will not only affect the nearby residents, but also pose a serious threat to the life safety of firefighters ...
