A Design Of Wireless Order System Based On MSP430 And CC2520

In recent years,as people living standard rise and consumption conception change,people act of food consumption purely in a "solution for the purpose of hunger type" diner dropped substantially,the proportion of service forms,catering style,atmosphere,pay more and more attention to such elements,chasing trendy consumption tendency has also forced restaurant frequently reveals new recruit,this business promoted the catering industry gravitated to the international catering tide constantly.In recent years catering market competition intensifies,and increase the catering industry segments for brand position,old,flavor building,respectively,traditional snacks emerged room,etc of distinctive brand or firms food brand.According to the catering industry experts predict the future in the catering industry competition,brand image,concept,service,atmosphere,popularity and reputation such aspects of the formation and international metropolis,gradually adapt to the modern catering business status.In today's society is the age of information explosion,but in the vast majority of the catering industry enterprise,information management concept is still only stay in "use financial software accounting,remember the extent play list".Because in many people's mind,so far,the catering industry is still a labor intensive industries,a clue,demanding more complicated,management.From this point of view,how to improve the management level is catering enterprises forever theme,rely on what platform to achieve? In this information age,information construction granted became the most ideal choice.On this basis,the wireless order system came into being.Wireless electronic order system is to use advanced 2.4 GRF wireless communication technology,embedded mobile database technology,and computer technology,touch screen palm for a catering toward full digital provides complete solutions.At present,the Wi-Fi,WLAN in wireless order such wireless technology has been widely applied in the system,and ZigBee is a kind of new wireless technologies,also gradually applied in wireless order system..With the advanced 2.4GRF wireless communication technology,embedded mobile database technology,and touch screen PDA.By then,some wireless technology such as Wi-Fi and WLAN have been used widely in wireless order system and a new technology---ZigBee is being used in this system.ZigBee is a wireless technology based on IEEE802.15.4 specifications,working on the 2.4GHz band,and is a two-way wireless communications technology with close distance,low complexity,low power,low cost and low data transfer rate,has the advantage of power,high reliability,low cost,short time,high level security,network capacity and ease network,and is a type of self-organizing network which supports star-construction,net-construction and clustered construction.So ZigBee has a wide field in home system control,building automation and the field of industrial control,and also has high value in the wireless order system and hotel management.This paper is mainly about the requirements of low cost and low power,study the popular radio Frequency Identification Technology of ZigBee,learn the framework of ZigBee protocol,discuss the principle and application of ZigBee,and designs a wireless order system based on CC2520 and MSP430 MCU with a CC2520 RF chip as the core.This system consists of handheld terminal,control center and PC database,the terminal and control center make up a star-network..The terminal recieves the order information through touch screen and sends it to the control center.The center collect all the data and implement.the base function of ordering with the help of PC database.The system can help waiters and Customers to order,add food,check out with the wireless order server in time,improve the Efficiency of service,lower Labor costs and help hotels to go to an information time.
