Automated atmosphere particulates monitoring device

Abstract

An automated atmosphere particulates monitoring device belongs to the technical field of environment monitoring. A rope reeling roller is installed on the upper end of a bottom board and is connected to a speed reducing box. The speed reducing box is connected to a large motor. A pulling rope is reeled on the rope reeling roller. The other end of the pulling rope is fixedly connected to a balloon. A particulate concentration monitoring sensor is installed on the lower end of the balloon. A first motor is installed on the lower end of the particulate concentration monitoring sensor and drives a rotary support thereunder to rotate. A laser emitter is installed on the rotary support and is driven to rotate by a second motor. An optical imaging sensor is arranged below the laser emitter. The first motor and the second motor are electrically connected to a controller through electric wires. The device is an unattended three-dimensional-space atmosphere particulate concentration measurement device, and can perform measurement to three-dimensional concentration distribution fields in large range, different altitudes and different positions.

Description

technical field [0001] The invention relates to an automatic atmospheric particle monitoring device, which belongs to the technical field of environmental monitoring. Background technique [0002] With the continuous development of industry, the living environment of human beings has been destroyed, and the situation of air pollution is severe, and atmospheric particles can cause smog atmosphere. Atmospheric particulate matter refers to the general term for solid or liquid particulate matter dispersed in the atmosphere, and its particle size ranges from about 0.1 μm to 100 μm. Its monitoring, analysis and research are the focus of current environmental protection work. The monitoring range of atmospheric particulate matter mainly includes TSP (Total Suspended Particulate) with an aerodynamic diameter of less than or equal to 100 μm, respirable particulate matter with an aerodynamic diameter of less than or equal to 10 μm There are three types of PM 2.5 fine particles.

AI Technical Summary

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
