Design And Implementation Of Intelligent Parking Guidance System Based On ZigBee

With the rapid development of China's economy,automobiles have entered many families.In m ajor cities of China,the number of cars is large,and the number is growing rapidly every year.The d ifficult situation of traffic congestion and parking has greatly affected the smooth traffic in the city a nd has become a major social issue.With the development of science and technology,more and mor e high-tech parking lots have been established in major domestic cities.The parking lot started to de velop in the direction of intelligence.Therefore,the research on the intelligent parking guidance syst em based on Zigbee proposed in this paper aims to solve the problems of people's quick search for p arking spaces and increase the utilization rate of parking spaces.It is of great significance to the cons truction of new high-tech parking lots in cities.The intelligent parking guidance system designed in this paper mainly includes four parts:(1)Parkin g information collection: This part uses a magneto-resistive sensor and Zigbee acquisition nodes to a chieve parking space information collection.(2)Parking information transmission: This article adopt s Zigbee wireless communication method to transmit parking information to the main control unit.(3)Parking data processing: The use of STM32-f103 to achieve data storage and communication with t he host computer and management of parking spaces.(4)Announcement of parking spaces: includin g induction screen announcement and host computer announcement.Among them,the upper comput er is programmed with Visual Studio 2010 software,and data transmission with the main control unit is realized through the RS-232 serial port to realize the display of various parking spaces,and the st atistical data of the parking spaces/remaining parking spaces.In addition,this paper also gives a deta iled overview of the working principle of the magnetoresistive sensor and the parking space detectio n algorithm combined with the magnetoresistive sensor,the principle and advantages of Zigbee wirel ess communication,and the Z-Stack protocol stack.
