摘要
针对自动泊车系统竞赛的研究,设计以控制台与小车串口通讯的自动泊车系统。键盘通过STC12C5A60S2处理器发出库位选择指令,小车STM32处理器接收指令,控制H桥电机驱动电路,控制小车前进、转弯、后退等操作;库门激光传感器检测小车进出库时刻并发送至控制台;经控制台处理器计算,由LCD同步显示;设计红外避障电路;编写了相应的控制程序,测试表明能够实现小车自动泊车、计时计费、避障功能。
In order to study the automatic parking system competition, an automatic parking system is designed to commun- icate with the serial port of console and trolley. The STC12C5A60S2 processor to issue a location selection command by the keyboard , and the STM32 processor of the car receives instructions, and control the H bridge motor drive circuit, so the car goes forward, turn, back and other operations; library door laser sensor detection car out of the library And sent to the console; calculated by the console processor, synchronized display by the LCD; design infrared barrier circuit; prepared a corresp- onding control procedures, testing that can achieve car automatic parking, time billing, obstacle avoidance function.
