Abstract

In order to further explore the networking and application technology of wireless sensor networks, a wireless sensor node based on ZigBee is designed and developed, and on this basis, a novel application of environmental monitoring is carried out in this paper. The proposed building intelligent system mainly consists of environment monitoring platform and mobile APP. This environment monitoring platform dividing into two parts of Host computer and lower computer, and the major collecting parameters of the sensors in the proposed platform are temperature and humidity, light intensity, carbon dioxide, and PM2.5 etc. Moreover, in the APP we designed, the APP interface consisting of menu bar and four sensor modules, which cover login interface, main interface, real-time display interface, system setup, alarm function, data storage, historical data query, port setup and help parts. And the background data is stored in the SQL Server 2008 database. It can overcome the drawbacks of the traditional existing platforms such as low intelligent and difficult0network layout. The results showed that the environmental monitoring is closely connected with people's life. It can make a prediction on the environment pollution alarm and also provide data basis for energy saving in the construction field. Based on the above findings, it is concluded that it has very important significance to promote the construction of sustainable development of the monitoring of indoor and outdoor environment.

4 Conclusion

With the integration of wireless sensor network and big data technology, building intelligent system has entered a new stage of development. Wireless sensor network has been widely applied. In view of the particularity of building space, this paper studies the networking of wireless sensor network and the application of environmental monitoring in the building. Based on the analysis of ZigBee network topology, protocol stack and node functions, this paper analyzes the ZigBee wireless ad hoc network, and conducts ZigBee networking simulation and experiments. It verifies the self-organization and self-healing of ZigBee wireless sensor self-organizing network. The building intelligent system environment monitoring platform and mobile APP are designed and developed. Environmental monitoring is closely related to people’s life. It can predict and alarm the environmental pollution, and also provide data basis for energy saving and consumption reduction in the field of architecture. As a result, achieving building indoor and outdoor environment monitoring is very important for promoting sustainable development of buildings.
