Research on application of real-time database for air quality automatic monitoring system

Abstract

With the increase of city air monitoring sites and monitoring project, monitoring instruments and monitoring data are increasing rapidly. When using the traditional relational database in processing huge real-time data, the throughput and timeliness of monitoring system has been unable to meet the needs of the business. In order to solve this problem, this paper introduces the real-time database into the air quality automatic monitoring system. According to the design principles, the paper outlines the four aspects of the design: the composition of the system, the overall structure of the system, the data flow and the network topology. Aim at assembling the embedded system architecture, distributed system, database technology, network browser/server computing mode, client/server network computing technology, and large-scale computer application system of virtual private network connection based on public network. In the specific design, this paper design substation and central station architecture based on the real-time databases and complete the function of field data collection and storage, equipment control, data transmission, human-computer interaction, data exchange interface with third party system and other function. Finally, according to the observation results of the city air quality automatic monitoring system, the project realizes the functions of the system and improve the real-time quality of environmental air monitoring and the capacity of instrument supervision.
