摘 要:设计了一种简易的不停车收费系统。设计用单片机AT89C52控制无线模块,形成发射机和接收机,实现车辆信息的传递,并通过串口显示在计算机上。采用的nRF24L01无线模块、数字信号编码和二次调制方式之间的加密通信原理,软件设计采用自上而下的模块化设计思想,使系统具有分布式、小型化的特点。测试结果表明,该系统具有抗干扰性强、功耗低、反应速度快、传输效率高和简单的特点。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 andencryption communication principle between digital signal code and secondary modulation mode are adopted in the system. Themodular 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 powerconsumption,fast reaction rate,high transmission efficiency and simple structure.
