Above shows the block diagram of the project. This project involves the following component like AVR Microcontroller, LCD, RF ID, Serial communication etc.
Advantages:
1. Avoids time wastage
2. Details of each vehicle are maintained, so it becomes easy for verification.
3. Ease of operation
4. Highly reliable
In this system an RF Transmitter (called as RF tag) is placed on the vehicle which transmits signal of a selected frequency. This signal corresponds to the identification number of that particular vehicle. The receiver at the check-post station gets the signal and the Microcontroller produces a code based on that signal. This is further sent to the computer in the check-post office, which in turn logs on the server. The server validates the data regarding that particular vehicle and decides either to pass the vehicle or hold the vehicle into custody mode.
Use this for your reference and study only.
