Design And Implementation Of Wireless Calling System For ZigBee

As a new kind of wireless communication technology, ZigBee is low-powered,low-cost, low-complexity and short-delay. In this paper, ZigBee’s hardwaretechnology and software technology are both researched and a kind of wirelesscalling system based on ZigBee is proposed.At first, by studing at ZigBee, a realizing method of ZigBee’s wireless callingsystem is introduced in this paper. The chip CC2530of ZigBee is used to finish thehardware design and implement of the wireless calling system, which mainlycontains the ZigBee chip, the battery, a crystal oscillator, the download circuit,antenna, LCD screen and a warming module.Then, the design and programming of the wireless calling system’s software isrealized in this paper. The software consists of5modules: the Auto-Networkingmodule, the button striking module, the calling request transmission module, thecalling recognition module and the data statistics module. Each module is designedand implemented in the paper.At last, by combining the hardware and software,the system’s functions andcapabilities are also tested in the paper.It indicates that, the prototype system worksnormally and can reach the expected goal, and the functions of sending warminginformation from each terminal to the surveillance center and transmitting callinginformation from the surveillance center to terminals are all realized in this paperIn a word, this paper provides a new realizing method for wireless callingsystem, and it has a wide prospect in real life.
