Abstract
In order to solve the disadvantages such as dispersed monitoring points, problems in wiring and poor real-time capability etc. in existing environment monitoring, the remote real-time monitoring system based on wireless sensor network is designed in this paper for the air environment in chemical industry zone. The optimal method is adopted to balance the load on the basis of clustered control technology, so that the energy consumption speed of the node can be reduced; and in the meanwhile, the gateway algorithm called optimized cluster distribution and based on maximum energy-path selection among multiple paths is also proposed. Finally, the software and hardware system of monitoring system network used in chemical environment is researched, and a set of low energy-consumption system is designed based on demands; the hardware aspect includes the function and structure circuit design of the system; and the software aspect includes the MAC layer design and upper layer system. The experiment result indicates that this system is of strong operability and flexibility, which can be used to adjust the power usage of the node effectively and improve the service life of the wireless sensor network, thus the chemical factory can be under the monitoring status continuously, due to which the instantaneity and continuity of the monitoring data as well as human and property safety can be guaranteed.
