| Accompanied by the process of industrialization, the natural environment has beenseriously damaged, the frequently appearance of extreme environment has warning peoplethat we should take some solutions to protect the environment. How to efficiently monitorthe environment and provide scientific guidance for the subsequent management is a bigproblem to be solved, it is very necessary for us to build a system used to monitorenvironment in the real time, so we design a wireless ZigBee system which is shortdistance and low power.The ZigBee and several other short-range wireless communication technology isanalyzed and compared in the paper, the conclusion is that ZigBee technology is suitablefor wireless environment monitoring network. The processing platform is built bySTM32L151, using ZICM2410module forming network platform, and remotecommunication for environmental monitoring are built up with SIM900B. The datatransmission mechanism is signal hop which is from terminal node to coordinator and thensend to remote management center by GSM(Global System for Mobile Communications).The terminal node can join or break from network freely. The remote management centercan use RealTerm software to receive and storage the serial data, and data display useECharts which is a open source project.In this paper, we design a wireless environment monitor system based on Zigbeetechnology, which has advantages of low cost, low energy consumption and small volume.The test result shows that, our system can build wireless network topology and collectenvironment data in real-time. Our system has high extensibility and can implement morefunctions by adding various perceptrons on sensor nodes due to different requirement. |
