Vehicle-mounted atmospheric environment monitoring method and system

Abstract

The invention discloses a vehicle-mounted atmospheric environment monitoring method. The vehicle-mounted atmospheric environment monitoring method comprises the following steps: S100, pre-storing position information of each monitoring base station in an area; S200, acquiring a first environment monitoring value, which at least contains VOCs (volatile organic compounds) and a first wind direction, from each monitoring base station; S300, when the first environment monitoring value is larger than a set second threshold value, judging that the first environment monitoring value is an abnormal value and acquiring the position information of the base station corresponding to the abnormal value; S400, acquiring the state information, which at least comprises the position information of the vehicle, of each monitoring vehicle; and S500, transmitting scheduling information to the available monitoring vehicle which is nearest to the base station corresponding to the abnormal value. With the vehicle-mounted atmospheric environment monitoring method, comprehensive monitoring can be realized and monitoring blind spots are avoided.

Description

technical field [0001] Generally speaking, the present invention belongs to the field of environment, and in particular relates to a vehicle-mounted atmospheric environment monitoring method and system. Background technique [0002] Ozone and PM2.5 have become the "culprit" and "main culprit" of urban air pollution, while VOCs (volatile organic pollutants) are the common precursors of fine particles such as ozone and PM2.5. VOCs have the characteristics of low concentration and high toxicity, and are called "shadow killers". At present, there are traditional laboratory methods and online monitoring methods for fixed base stations to monitor VOCs. Traditional laboratory testing methods have disadvantages and deficiencies such as long testing cycle, slow data issuance, and poor flexibility, making it difficult to achieve fast and simple on-site testing. The existing base station online monitoring methods also have some shortcomings: for example, there are blank spots in samp...

Problems solved by technology

Traditional laboratory testing methods have long testing cycles, slow data issuance, poor flexibility and other shortcomings and shortcomings, making it difficult to achieve fast and simple on-site testing

The existing base station online monitoring methods also have some shortcomings: for example, there are blank spots in the sampling, the sensitivity of the online detector is not high, the data cannot be compared with the laboratory analysis, and there are defects in the accuracy and reliability of the data

Our country has a vast territory, and the number of fixed monitoring base stations is limited. In order to facilitate monitoring, atmospheric environment monitoring vehicles are generally used at present. Due to the variability of the internal and external environments of the vehicle, the accuracy of the detection data of VOCs in the current atmospheric environment monitoring vehicles and poor reliability, and cannot realize real-time online monitoring

When sudden VOCs pollution occurs, it is necessary to quickly determine the location of the pollution source. The current monitoring vehicle does not have this function
