Vehicle-mounted atmospheric pollution source monitoring device and method

Abstract

A vehicle-mounted atmospheric pollution source monitoring device comprises an instrument box, a suction cup, a wind speed and direction assembly, an antenna and a portable computer. A battery module, a sensor module, a GPS module, a wireless communication module, a structural mainboard, an MCU device, a sampling gas circuit and an electronic compass are arranged in the instrument box; the method comprises the following steps: the portable computer communicates with the MCU device, collects measurement data of the wind speed and wind direction assembly and the electronic compass, and calculates the relative wind speed and wind direction in the running process of a vehicle by using the measurement data; measurement data of the GPS module is acquired and the course and speed of the vehicle are calculated; the real wind speed and direction in the environment is calculated by using the relative wind speed and direction and the course and speed; and the portable computer collects data of the sensor module in real time, if a preset alarm value is exceeded, a built-in electronic map of the portable computer is called, suspicious pollution source units are searched according to the real wind speed and wind direction and the vehicle position, and the pollution source units are directly judged or judged through further voyage according to the number of the suspicious pollution source units, the wind speed and wind direction and the sensor data.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a vehicle-mounted air pollution source monitoring device. Background technique [0002] The quality of the atmospheric environment is of great significance and role in human survival. The World Health Organization reports that 8 million deaths are directly caused by air pollution every year. The impact of the greenhouse effect is becoming increasingly prominent. The global average The temperature is rising year by year, and the improvement of environmental quality is imminent. Atmospheric environment monitoring is of great significance. With the increasing field of atmospheric environment monitoring, the rapid increase of atmospheric environment monitoring tasks and the continuous improvement of environmental management requirements, it is imminent to promote environmental monitoring services. In order to realize the environmental atmospheric monitori...

Problems solved by technology

[0003] The current common environmental monitoring system is fixed in a certain area or on both sides of the road, which has certain limitations for environmental monitoring. The special mobile atmospheric environment monitoring vehicle needs to use specially modified large and medium-sized vehicles, equipped with special large-scale instruments and equipment , is not only expensive, but also has high requirements for users, and it is difficult to popularize and apply it in large quantities. Therefore, it is necessary to have a vehicle-mounted air pollution source monitoring device that can be used without modifying the vehicle to solve this problem
