The block diagram for receiver module

Explanation of Block Diagram

After receiver module detects data from transmitter. If data detected, red LED will turn off, blue LED will blink and PIC microcontroller will send RFID data to computer. Else, system will up count timer. If timer more or equal to 3 seconds, red LED will turn on and system will send error data to computer.

User need to key in data for train and RFID. Computer detects data from PIC microcontroller. If RFID data in, system will show train name and RFID data on screen. Else, if error data detected, system will show transmitter fail time and date on screen. The connector RS232 and voltage level converter is using to interface between PC and receiver circuit.
