Abstract
To solve such defects as scattered monitoring points, difficult wiring and poor real-time capability of the current environment monitoring, a kind of remote real-time monitoring system for the air environment of chemical industrial areas based on wireless sensor network (WSN) is designed in this paper. Main functions of this system are as follows: the sensor nodes distributed in chemical industrial areas can collect air environment parameters, the data can be transmitted to data centre of the central control room via base station for real-time processing and analysis, remote terminal users can give round-the-clock real-time monitoring to the air quality through the internet, it can also give real-time alarm as to air environment of the areas affected by such emergencies as pollution and the dramatic change of environment, and it could provide decision support as to prevention of air environment pollution. It is proved by the experimental results that wireless sensor network can not only overcome the problem of low reliability of the traditional environment monitoring system but also increase new monitoring function. Thus, it can be concluded that the wireless sensor monitoring system based on path algorithm can solve the problem of real-time monitoring on the environment of chemical industrial areas effectively, and it shows the great application value in the unmanned environment monitoring in harsh conditions and in the event tracking.
