Design Of Network And Communication Of Parking Spaces Based On ZigBee Technology

Along with the rapid economic development, the number of cars in the majorcities also increased. There is often a traffic jam phenomenon. The main reason isthe increase of the number of cars in the parking place caused by the vehicles.For the parking lot managers,they all hope a intelligent parking lotcommunication system with high communication efficiency,long transmissiondistance and high system stability will be producted. ZigBee technology is paidmore and more attention by society for its low power consumption, low cost, lowcomplexity and other characteristics. And the same time its platform cost is lowand the application field is very wide.This paper researched the network design scheme of parking in the parking lotbased on ZigBee technology. Combining with the relay the network sets up wayin the mode of the traditional communication, this design built the parking lotsystem network using the ZigBee own agreement standard to realize the wirelesstransmission between managers and vehicles.Through the thorough understanding of the present situation of the parking lotsystem and the prospect of the development of the ZigBee technology, analyzingthe system structure and the topology structure of ZigBee, combining the relaythe network sets up with Multi-hop routing gorithm under the traditionalcommunication mode, this paper designed the network system of the parking lot.This article mainly analyzed the hardware design and software realization ofthe parking lot system, used STM32-103microprocessor chip and CC2530wireless chip to constituted the parking network hardware design of the parkinglot and designed the hardware circuit of the transport of nodes based on theEJOY MCU wireless transmission module. In IAR7.2H integrated development environment, based on ZigBee2007edition protocol stack, this paper designedthe wireless and serial interface communication data frame programs and testedthe system transmission distance using the production development tools of theTI company.ZigBee technology applicated in the parking network system of the parking lot,not only can achieve the effective management and the real-time monitoring toimport and export vehicles but also improve the system stability hugely. Thesystem research will have broad application prospects and market.
