一种声音引导倒车系统设计研究

Research on design of voice guidance system

采用声音引导电机控制ASSP芯片(型号MMC-1)实现了可移动声源的运动,利用单片机8051系统,无线收发芯片PT2262/2272编码电路解码,研制并设计了一套模拟停车的声音引导系统。该系统由可移动声源(智能小车)和声音接收控制电路等组成,能够利用声音信号将自制电动车准确停靠在指定位置,通过无线传输模块控制车载单片机,从而控制小车运动,到达指定位置具有光和声音的指示,模拟实验得到很好的效果,值得推广到汽车倒车系统中应用。

Using the motor control ASSP chip （ Model MMC - 1 ）, and achieved the movement of mobile sound source, and also used the microcomputer systems8051, wireless transceiver chip PT2262/ 2272 coding circuit decoding, developed and designed a simulation of parking the voice guidance system. It concludes tow parts： moving voice source and control system of voice receives. This system can park home-made electric car at the right place with voice signals, arrived at the designated location with a light and sound instructions. The system gets good results. Is worthy to he popularized to auto reverse system application.
