Movable GNSS-based urban bus-mounted air pollutant concentration monitoring system

Abstract

The invention discloses a movable GNSS-based urban bus-mounted air pollutant concentration monitoring system. The movable GNSS-based urban bus-mounted air pollutant concentration monitoring system comprises a vehicle-mounted system, a data processing and management system and a visualized display system; the vehicle-mounted system is installed on the top of a bus, comprises an air pollutant concentration monitoring sensor, a GNSS receiver, a power supply apparatus and a data transmission device, the data processing and management system receives the data transmitted by from the data transmission device, and processes and stores the data, and uploads the processed standard data to the visualized display system; and the visualized display system utilizes the standard data processed by the data processing and management system to display a real-time distribution diagram of the urban air pollutant concentration and a tendency diagram of the pollutant concentration on a fixed point along with the time and provides a reported product of the air pollutant concentration. The movable GNSS-based urban bus-mounted air pollutant concentration monitoring system can automatically monitor the concentration of the urban air pollutants with high time-space resolution ratio, and has the advantages of low cost, ease operation and high practicability.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a GNSS-based mobile air pollutant concentration monitoring system on an urban bus. Background technique [0002] In recent years, with the rapid development of industrialization and urbanization and the increase of energy consumption in China, air pollution has seriously affected people's daily life and brought huge economic losses to the society. Therefore, the concentration of air pollutants in cities Only by monitoring the spatial and temporal distribution can we carry out targeted prevention and control of air pollution. However, judging from the current status of monitoring the concentration of air pollutants in domestic cities, the overall density of measuring stations is too low and it is difficult to monitor in real time. Domestic near-surface atmospheric pollutant concentration observations are mainly based on surface meteorological station observations and emergency mobile observ...

Problems solved by technology

For the observation of ground meteorological stations, because fixed stations can measure at the same time, the data has the advantage of time consistency, but because the construction cost of meteorological observation stations is high and limited by the environment, the distribution density is too low to adapt to the air pollution in the city The demand for real-time monitoring of the concentration distribution of substances; for mobile observation, due to its mobility, multi-poi
