Development Of Smart Home Experimental System Based On ZigBee

In recent years, with the rapid worldwide development of IOT (Internet of Things), the WSN (Wireless Sensor Networks), which is one of the most important support technical of IOT, has become a focus in research and development. Now many colleges and universities have set up the IOT course. How to teaching and practicing WSN in laboratory is one of the most important problems need to be solved in the field of IOT education.After carefully investigation on development of WSN and the existing experimental equipments, this thesis designs a new integrated modular smart home experimental system for developer training. The whole system is based on ZigBee technology, considering the current domestic and foreign R&D level.The main work of this thesis includes:(1) According to requirement analysis of the WSN experiment practice, and the disadvantages of related products on the market, determine the overall scheme of the experiment system.(2) The hardware design of the system. The core part of the hardware is based on CC2530chip. Five different modular function modules is designed and implemented. Each of them is composed of a ZigBee module, a bottom function module and a sensor control module. These modules can realize the function of analog sampling, analog output, relay control, digital quantity acquisition/output and alert control.(3) To meet the needs of learning networking, application development of Z-Stack, three series of experiments were designed respectively, namely basic experiments of Z-Stack, network acquisition control experiments and comprehensive experiments. All demonstration programs are designed and implemented.(4) Design PC-based experimental software for friendly interactive interface, including data collection, communication and displaying, control command setting, online modification of network parameters and dynamic displaying of WSN topological structureThe repeated fundamental testing and comprehensive application of the smart home cabin shows that the designed experimental system is convenient to use and combination, be able to long-time stable operation, meet the desired requirements of experimental system.
