Abstract: At present,the lack of unified data acquisition and transmission management standards of air quality monitoring data in China has caused difficulties in data integration.There are multiple sets of environmental monitoring data acquisition and transmission software,and data cannot be shared among monitoring networks,forming an information island.On the basis of analyzing the present situation and existing problems of data acquisition and transmission management of ambient air quality monitoring in China,this study proposes a design with good expansibility,universality and standardization for the system structure,communication protocol and data coding of ambient air quality monitoring data acquisition and transmission,in accordance with the existing standards and the actual business needs of ambient air quality monitoring in China.It is expected to promote the standardization of atmospheric environment monitoring equipment and system integration.So as to achieve the goal of high integration and interconnection of data between systems,full sharing of information resources,and mutual integration and close interaction of ambient air quality monitoring business.
