摘要：

This system combined speech recognition and wireless technology together. It overcame the defect that the chip was embedded in car body, which was far away from the speech source and leaded to high noise in traditional system. Moreover, the new system adopted ultrasonic rangefinder which made the car can avoid obstacles. The control process of this design was that speech information in SPCE061A were identified and translated into control commands, and then sent to a terminal device through ZigBee coordinator CC2430. Then the obstacle-avoiding information detected by the ultrasonic rangefinder together with voice control commands were transmitted to the 51 MCU, which analyzed these signals and finally decided the car's driven control signals.
