本设计系统是以单片机AT89C52作为小车的检测和控制中心。根据设计题目的要求,采用红外传感器作为小车的遥控接收电路,采用多用户、多通道遥控方式控制小车的启动、停止及状态转换,通过芯片组MC145026/MC145027实现发射接收“0”、“1”信号功能,并对其编码,然后将编码输入AT89C52单片机。单片机经过处理将信号送入驱动芯片L298控制电机使电动车实现前进、后退、左右转弯、正8、反8等功能。
The design system is based on microcontroller AT89C52 as a car detection and control center. According to the requirements of the design topic, the infrared sensor is used as the remote control receiving circuit of the car. The multi-user and multi-channel remote control modes are used to control the start, stop and state transition of the car. Transmitting and receiving “0” and “1” through chipset MC145026 / Signal function, and its encoding, and then coding input AT89C52 microcontroller. After processing the signal sent to the driver chip L298 microcontroller to control the motor so that the electric car to move forward, backward, turn around, is 8, anti-8 and other functions.
