A simple electronic toll collection system is designed in this paper. The single chip AT89C52 is used in this de-sign to control the wireless module and form the X-mitter and receiver for actualizing the information transmission of vehicles. The information is displayed on the computer through the receiver's serial port. It employs The wireless module nRF24L01 and encryption communication principle between digital signal code and secondary modulation mode are adopted in the system. The modular design idea from top to bottom is utilized in the software design to make the system has the distributed and miniaturiza-tion characteristics. The testing results show that the system has the merits such as the strong anti-interference ability,low power consumption,fast reaction rate,high transmission efficiency and simple structure.
