Air environmental quality monitoring system

Abstract

The invention discloses an air environmental quality monitoring system, which consists of a monitoring center platform and several groups of monitoring nodes connected to the monitoring center platform through a GPRS wireless network. Each monitoring node comprises a temperature and humidity sensor, a PM2.5 sensor, a GPS position indicator and a micro control unit. The monitoring center platform includes a data storage server and a monitoring terminal. The system provided by the invention adopts a work mode involving the monitoring nodes and the monitoring center platform, the monitoring nodes use MSP430 single chip microcomputer as the control core, employ the temperature and humidity sensor and the PM2.5 sensors for data acquisition, and the monitoring center platform uses a display mode by which the monitoring nodes are presented on a map, so that distribution of the monitoring nodes can be seen visually, and the form of a data report form or trend curve diagram can be selected for viewing the monitoring situation at each monitoring point, thus providing basis for the management department to make decisions. At the same time, the system provided by the invention solves the problems of acquisition, transmission, power consumption and data management, and has a high intelligent degree.

Description

technical field [0001] The invention belongs to the technical field of system engineering and relates to an environment monitoring system, in particular to an air environment quality monitoring system. Background technique [0002] The quality of air quality reflects the degree of air pollution, which is judged according to the concentration of pollutants in the air. Air pollution is a complex phenomenon, and the concentration of air pollutants at a specific time and place is affected by many factors. The emission of man-made pollutants from stationary and mobile pollution sources is one of the most important factors affecting air quality, including vehicle, ship, and aircraft exhaust, industrial pollution, residential living and heating, and garbage incineration. Urban development density, topography and weather are also important factors affecting air quality. [0003] The existing air environment quality monitoring system has problems such as wide monitoring area, high ...
