Why Vehicle Access Control system ?• Today, in a growing emphasis on personal

and property safety, the control of vehicles access authorization and the management become more problem.

• Vehicles access authority, access time and access method via computer, is safe and convenient.

Why Zigbee…?• At present, the most widely approaches used in

vehicle management are: 1) Artificial inquiry identification method waste of labor and difficulty of information

communication 2) Image recognition method large investment, low recognition rate and

susceptibility to weather 3) Contact IC Card Management difficult to maintain, large investments in

infrastructure facilitiesThese shortcomings are overcome by Zigbee

What is Zigbee…?

• Zigbee is a Wireless sensor network based on IEEE 802.15.4

• It is an emerging short-range, low-speed, low-power wireless networking technology.

• Zigbee has following featuresLow data transmission rateLow power consumptionLow costLarge capacity of the network

SYSTEM BUILDING OVERVIEW• In this Zigbee network topology uses the star-

shaped wireless network topology-

• Monitoring center is composed by a computer and a network coordinator

Continue…• Monitoring responsible for communication with its

child nodes, data collection and dissemination of control information.

• It establishes and manages the network, receives the data and displays them on the LCD

• Terminal device may be either FFD or Simplifies device RFD

• RFD node in this system has been installed in each vehicle

SYSTEM IMPLEMENTATION

A. Hardware platform

Continue…

B. System software design

Software Design of Coordinator

Software Design of Terminal node

SYSTEM TEST AND RESULTS• C51RF-3-ZDS emulator has all C51 source level

debugging functions, such as high-speed code download, on-line DEBUG, hardware breakpoints, single step, variable observation, registers observation

A. Build the hardware platformB. Compile, download and debug procedures with

the IAR software integrated development environment

C. Run the programD. Analyze the data frame

CONCLUSION• This design utilizes ZigBee WSN technology to realize the

wireless management and dispatch system of vehicle access

• This system has realized the following functionsa. When a vehicle assess to the entranceb. The transmitter installed in the car sends related

informationc. The receiver which is set in the access control officed. After successfully received the vehicle’s information, the

receiver passes the data to microcontroller to decode them

e. The controller can query all the information in database, including license plate number, driver number and so on
