ABSTRACT
As the fast development of the society and economy, the issue of terrible energy consumption of the campus construction is increasingly prominent, the campus energy there is a big waste. In order to guarantee normal operation of the campus in all areas of energy demand, and realize effective energy saving, shall establish energy remote monitoring and management system, obtain the real-time data of campus energy consumption , on the campus of various energy system for distributed monitoring and centralized management.
For the energy consumption, how to efficiently collect, integrate and analysis data, so that realize to remote monitor and manage of energy consumption remotely, for the construction of green energy-saving campus and the society are important. Therefore, this paper based on the campus of Zigbee transmission wireless gateway has carried on the related research of energy saving supervision platform. Main works are as follows:
1、Starting from the background of the construction of energy saving campus and significance, introduced the energy consumption status of campus at home and abroad briefly, and analyzed the detailed situation of energy consumption in Hefei university of technology, explains the necessity and the basic framework of campus energy saving platform.
2、Campus energy regulation is based on the principle of virtuous cycle of ecological system, relied on electronic information and Internet engineering to establish a new system. Introduced based on Zigbee transmission intelligent multifunctional gateway this solution, multifunctional gateway is an open, modular, programmable bubbled into access platform, it can realize to use different standards, different spectrum sensing network to communication network, the demand analysis after its function. Multifunctional gateway by using open and pluggable Zigbee wireless sensor network access module, can quickly adapt to all kinds of wireless sensor technology, realize to plug and use at any time.
3、At the end of this paper, we described the content of Zigbee test scheme, including its platform compatibility, product certification, and interoperability testing, and finally summarizes the main works and innovations in the dissertation and proposed improvements.
