摘要
利用光电编码器、MC9S12DG128单片机、LM1881和NRF2401收发芯片设计智能车无线调试系统。将光电编码器检测到的电机转速脉冲信号和同步视频信号分离器LM1881分离出的视频信号经MC9S12DG128单片机处理后,由NRF2401模块实现信号远程传输,再通过RS232接口与PC机进行高速通信,从而实现远程调试参数的功能。
The wireless debugging system was designed by using photoelectric encoder,MCU （Micro Controller Unit） MC9S12DG128,LM1881 and single chip transceiver nRF2401.photoelectric encoder is used as a speed sensor,and LM1881 is used as a video sync separator which processes video signals,the data is acquired by microprocessor for processing and long-distance transmitting by nRF2401.This system used RS232 interface to the high-speed communication with PC,realizing the purpose of Long-range debugging.The distance of transmission indoor is about 50 meters,up to 100 meters outdoors;this system has a high practicality in debugging of smart car.
