This document describes a vehicle access control system using Zigbee wireless technology. It discusses the need for such a system due to shortcomings in existing approaches. It then provides an overview of Zigbee and describes how a star network topology is used. The hardware and software designs are explained at a high level, including the coordinator, terminal nodes, and use of an emulator for debugging. Testing showed the system can successfully transmit vehicle information from transmitters to receivers and allow the access control office to query a database based on the received data.

- 3. • 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.
- 4. • 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 facilities These shortcomings are overcome by Zigbee
- 5. • 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 features Low data transmission rate Low power consumption Low cost Large capacity of the network
- 6. • In this Zigbee network topology uses the star-shaped wireless network topology- • Monitoring center is composed by a computer and a network coordinator
- 7. • 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
- 9. B. System software design
- 12. • 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 platform B. Compile, download and debug procedures with the IAR software integrated development environment C. Run the program D. Analyze the data frame
- 13. • This design utilizes ZigBee WSN technology to realize the wireless management and dispatch system of vehicle access • This system has realized the following functions a. When a vehicle assess to the entrance b. The transmitter installed in the car sends related information c. The receiver which is set in the access control office d. 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
