Development Of ZigBee Teaching Experiment System

In recent years, a variety of wireless communications technology are developing rapidly, greatly increasing the work efficiency and quality of life of people. As an important branch of wireless communication technology, ZigBee technology will surely play a huge role in the era of Internet of things in the future, because of its good features of low-cost, low power consumption, Self-Organized Network. However, ZigBee is a wireless network communication technology which is just emerging in recent years, many of its technical details still need to learn and improve, its application also need to promote.Based on the above, this thesis developed a set of ZigBee technology teaching experiment system by the popular ZigBee protocol stack and physical layer chip, so that beginners can quickly and flexibly master ZigBee protocol specification, hardware and software implementation in application development. The experimental system described in this article use the popular TI’s CC2430chip as a controller and RF module, equipped with the TI Z-Stackl.4.3protocol stack program as an experimental system software platform.This system consists of13subsystems, divided into a protocol analysis module, sensor application module, network communication module of three parts, and comprehensively and systematically tells about the development of the ZigBee technology. This thesis first introduces the ZigBee protocol specification and CC2430radio chip,and to understand the basic concepts of ZigBee technology is the theoretical premise to grasp the ZigBee technology. The following protocol analysis module explain and demonstrate the Z-Stack development methods by practices, as well as binding, secure transmission.This part is the key part to master the ZigBee technology development. Sensor application module consists of seven subsystems, and each subsystem in combination with a sensor proceeds to application development for ZigBee technology. this part is the main content of this teaching experiment system. The network communication module is the comprehensive of this system, and it strengthens the network management functions.This system is tested by experiments.It works well and can fulfill the designing requirements.
