Intelligent Environmental Perception System
Abstract: In this paper, the designed to automatically monitor the environment status, automatic control environment question the wisdom of environment perception system for automatic detection system, namely that were the focus of essence for a lot of structure applied in environmental monitoring. If you want to achieve wisdom environmental awareness, first of all need to be perceived as a foundation. While perception to sensors have high demands. Secondly, on the basis of the sensor network, the data transmission and acquisition are necessary to achieve the result of monitoring. Again, in the system of intelligent processing of sensory data, we need a monitoring interface for real-time observation system running situation, discover problems in time, handle problems, in order to ensure the normal running of the system. To sum up, this system consists of three layers of structure design, namely perception layer, transport layer and application layer. This article first introduced the related background of the topic, component software principle and some development of hardware and software required by the system, then the structure and the detail design of this system are introduced, and experimental results was verified.
