Company: Shenzhen Besian Intelligent Technology Co., Ltd.

Product Description: Drone-mounted Gas DetectorBackground OverviewWith the increasingly severe air pollution in our country in recent years, the proportion of pollutants has become heavier, and thus the task of air pollution detection and control in China is becoming more arduous. The state has deployed and improved particulate matter and gas detection equipment in most cities, forming a dense ground pollution source detection network combining national control points and provincial control points.However, we can also clearly see that there is still a large gap between the predictions made based on ground detection data from national control points and the development of actual environmental pollution conditions. In addition, the control measures implemented based on ground monitoring data, such as ground sprinkling, construction site covering, traffic restrictions, industrial production limits, boiler transformation, desulfurization and denitrification treatment, etc., have not yielded satisfactory results.As the third-generation remote sensing technology following aviation and aerospace remote sensing, UAV remote sensing technology has the advantages of three-dimensional monitoring, fast response, wide monitoring range, and small terrain interference. It is one of the important development directions for identifying pollution sources and monitoring concentrations during future atmospheric emergencies.However, due to the limited payload of drones, completing high-precision atmospheric environmental monitoring work requires high-precision sensor payloads, and there are few traditional sensors to choose from due to limitations in volume, weight, etc. Therefore, our company has researched and developed small, lightweight sensor payloads suitable for drone mounting to realize drone air pollution monitoring and drone fixed pollutant monitoring.Features of Drone-mounted Gas Detector●The software supports multiple drone manufacturers, including all DJI series●Thousands of gas sensors can be replaced at any time, and the system has an automatic gas type recognition function●Shell design with waterproof, windproof, dustproof, and anti-collision features●Real-time display and real-time transmission of monitoring data, and generation of corresponding trend curves●View historical real-time data, and simultaneously generate curve analysis charts, lists, and chart styles to display historical data, facilitating comparative viewing●Can display longitude and latitude, altitude, aircraft status, temperature, humidity, PM1, PM2.5, PM10, and real-time concentration values of thousands of gases●Detection accuracy can reach ppb level●Real-time wireless transmission of data to the ground terminal, and also real-time transmission to the server via GPRSDrone Gas Detection Payload Parameters●Applicable: Multi-rotor drones, fixed-wing●Detected Gases: PM2.5, PM10, NO2, SO2, CO, O3, VOC, etc. (optional)●Detection Principle: Electrochemical, Laser●Weight: 1000 grams (7 parameters)●Dimensions: 220×145×60mm●Power Supply: 12-24V●Data Transmission Mode: 4G/Wireless data transmission●Working Environment Temperature: (-30~+60)℃●Working Environment Humidity: (15 ~ 95)% RH, non-condensing●Equipment Life: More than 5 years (excluding consumables)Drone Gas Detection Payload Dimension DiagramThe software of the ground receiving system is specially designed dedicated software for receiving, decoding, displaying, processing, and reporting the above-mentioned monitoring and detection data. It is two relatively independent software separate from the flight control software. When the drone flies normally with our company's gas detection equipment, it can detect concentration values in real time and transmit them back to the ground software for data analysis and display. It also supports multi-detector synchronous data return and processing functions.The data analysis software platform mainly includes functions such as real-time data display, checking whether the detection environment data status is normal, alarm value points, real-time data value change trends, and historical data query and export, which are synchronized in the ground receiving system.(1) Real-time data display is shown in the figure below:Data Display Monitoring Large ScreenThe software platform can display corresponding detection data and change trends in real time, integrating air quality gas sensor data and toxic gas emergency monitoring data into a unified platform for unified management and comprehensive display. Gas sensor data use different colors to represent different pollution levels.(2) Historical data query is shown in the figure below:Historical Data Query InterfacePerform simple statistical analysis on historical monitoring data of various points, such as daily variation analysis, time series analysis, etc., helping the purchaser save the time cost of manual analysis, and also helping the purchaser understand the basic pollution status.Through the flight mission function, the Besiyun monitoring platform can specifically display the flight route and real-time concentration display during the flight. It displays through real-time data, pollution concentration levels, etc., and is also compatible with gimbal synchronous display; realizing synchronous display of data and video.1 System Structure and Working PrincipleThis system mainly consists of unmanned aerial vehicles, Besian BSA/QT-UAV gas detectors, data transmission/GPRS, ground stations/servers, and data processing software. It is mainly used to detect atmospheric air quality AQI and emergency detection of toxic and harmful gases, with an accuracy of up to 1PPB. It changes the traditional fixed-point detection, making gas detection flexible, fast, accurate, and convenient.2 Software Implementation of Gas Concentration Data AcquisitionIn terms of gas detection, there are tens of thousands of gas types, ranges, precisions, etc. In order to simplify user operation and cost, our company has specially designed a set of intelligent sensor series. It has a complete set of software information systems, effectively dividing all detectable gas types to realize a fully intelligent recognition system. Customers can match different sensors according to different detection scenarios; making drone gas detection very flexible and unaffected by the payload.Application Fields: Mounted on drones, cars, robot inspections, ships, etc.1.Fire emergency monitoring and investigation of leakage sources of danger2.Pipeline leakage inspection3.Air quality detection4.Enterprise emission pollution detection5.Monitoring of polluted gases around chemical, petroleum and other enterprises6.Monitoring of exhaust gas emissions from ships at ports and wharves7.Rapid environmental screening and locking8.Safety inspection by robots in specific areas and special warehouses more>
