Automated atmosphere particulates monitoring device

Abstract

An automated atmosphere particulates monitoring device belongs to the technical field of environment monitoring and includes a bottom board, a pulling rope, a particulate concentration monitoring sensor, a communication module, a balloon, a controller, a rope reeling roller, a large motor, a speed reducing box, and an electric wire. The rope reeling roller is installed on the upper end of the bottom board and is connected to the speed reducing box. The speed reducing box is connected to the large motor. The pulling rope is reeled on the rope reeling roller. The other end of the pulling rope is fixedly connected to the balloon. The particulate concentration monitoring sensor is installed on the lower end of the balloon and is electrically connected to the communication module. The communication module is electrically connected to the controller. The particulate concentration monitoring sensor is electrically connected to the communication module through the electric wire. The device is an unattended three-dimensional-space atmosphere particulate concentration measurement device, can perform measurement at all altitudes lower than 2 km with three-dimensional concentration distribution fields at different positions.

Description

Technical field [0001] The invention relates to an automatic atmospheric particle monitoring equipment, which belongs to the technical field of environmental monitoring. Background technique [0002] With the continuous development of industry, the human living environment has been destroyed. Among them, the situation of air pollution is severe, and atmospheric particles can cause haze. Atmospheric particulate matter refers to the general term for solid or liquid particulate matter dispersed in the atmosphere, with a particle size ranging from 0.1 μm to 100 μm. Monitoring, analysis and research on it are the focus of current environmental protection work. The monitoring range of atmospheric particulates mainly includes total suspended particulates (TSP) (Total Suspended Particulate) with an aerodynamic diameter of less than or equal to 100 μm, PM 10 (Particles with Diameters of 10 μmorless) and aerodynamic diameter of less than or equal to 2.5. There are three types of μm fine p...

Problems solved by technology

[0004] ①At present, some institutions use UAVs to conduct measurement research, and the labor cost is high, which is suitable for less frequent measurements. The airflow of UAVs also affects measurement errors;

[0005] ②Using hot air balloons, hydrogen balloons, and helium balloons to carry out measurements, suitable for single measurements, not suitable for multiple measurements;

[0006] ③Using the lidar monitoring vehicle can complete the measurement of the concentration of atmospheric particulate matter at different heights and distances, but its cost is relatively high, close to 10 million yuan, which is not conducive to large-scale promotion
