Design Of Indoor Environmental Monitoring System Based On ARM

Nowadays, with the rapid development of electronic science and technology, it has a significant influence on the society which we benefit a lot in various ways. Human beings enjoy continuous prosperity and more convenience. However, as the old saying goes: everything has two sides, Electronic Science and technology gets us into trouble as well. Because it makes our environment be polluted. With the improvement of our living standard, people pay more attention to the environment, in particular, indoor environment. Therefore, it is urgent for us to monitor the indoor environment.First of all, the thesis introduces the background and significance of the indoor environmental monitoring system and the development status at home and abroad. Then it introduces the overall design of the system and the specific design process. Based on the ARM, the indoor environmental monitoring system was designed. This monitoring system consists of three parts: data acquisition and transmission module, intelligent gateway module and remote monitoring module. In addition, the data is processed by adaptive weighted fusion algorithm. The data acquisition and transmission module is composed of various sensors and Zigbee modules;The work principle and circuit design of each component are introduced in detail. The intelligent gateway module is mainly the ARM processor, and the Linux operating system is transplanted on the ARM processor. In this thesis, the Linux system and the ARM processor are described and designed in detail. The remote monitoring module includes the transplantation of embedded server boa and writing the HTML pages and the interaction design of a CGI program. Ultimately, the user can be informed the information of the indoor environment with using the browser. Finally, this system was tested successfully.This system which combines the wireless network of ZigBee, ARM processor, web server and data fusion technology can comprehensively, automatically monitor the environmental parameter and achieve the goal to monitor the indoor environmental condition in the distance.
