The unmanned aerial vehicle hazardous gas remote sensing imaging alarm system (model GIRDIS-1) is the world's first passive Fourier transform infrared spectroscopy visualization gas remote sensing monitoring and early warning device installed on unmanned aerial vehicles for aerial inspection. It is completely independently developed in China and has established a new application mode for non-contact large-scale stereoscopic monitoring of hazardous gases on unmanned aerial vehicles as a platform. The system is capable of real-time monitoring of toxic, harmful, flammable, explosive, and other hazardous gases, industrial emissions within a radius of several kilometers from the carrier. It automatically performs qualitative analysis and quantitative inversion, provides real-time alerts, and can detect over 400 types of substances.

The unmanned aerial vehicle hazardous gas remote sensing imaging alarm system can hover monitoring, flight monitoring, day and night fully automatic imaging monitoring and warning, visualize the whole process, real-time scene video, multi-dimensional intuitive dynamic display results, and the gas distribution and diffusion trend are clear at a glance, which is conducive to rapid source tracing and positioning; Automatically save and send back data, and support remote distribution. The system is safe, convenient, efficient, and sensitive, suitable for different environments and occasions.

1. Product advantages

(1) The unmanned aerial vehicle (UAV) approach overcomes terrain limitations, occlusion limitations, and distance limitations, allowing for more flexible and agile construction of monitoring areas. No need for on-site sampling, solving the problem of difficult sampling and detection in chimneys, water surfaces, and other places; For areas with unknown conditions, personnel and equipment do not need to enter the site to work and do not have to bear unknown risks.

(2) Remote real-time monitoring can automatically monitor the area within a radius of several kilometers centered on the carrier.

(3) Advanced infrared spectroscopy imaging telemetry technology, capable of day and night imaging detection.

(4) Aviation grade Stirling refrigeration ensures stable and accurate detection without the need for liquid nitrogen or auxiliary materials, making it agile and efficient.

(5) Quick identification, complete analysis and recognition in seconds. The product can be recognized based on one image through independently developed advanced algorithms and hardware design.

(6) There are many types of identification, including toxic and harmful gases, and polluting gases. The identification of gas types can be customized and expanded. It can simultaneously detect and analyze different gases mixed together and provide separate results.

(7) High safety, remote non-contact work, personnel and equipment will not be harmed by hazardous gases; Passive detection does not radiate energy to the detection area, avoiding the danger of triggering flammable and explosive gases within the detection area.

(8) It can dynamically display the distribution and diffusion trend of gases, provide real-time gas orientation, and facilitate traceability and positioning.
