摘要：该声音导引系统由声音导引主控系统和小车控制系统两部分组成。声音导引主控系统主要由主控MCU、声音接收部分、无线发射模块组成。小车控制系统主要由MCU、固化模块NEC、电机驱动部分、声光部分及无线接收模块组成。该系统的最大特点在于其软件设计使用层次化、模块化设计方法，系统低功耗，性价比低。经调试和测试，系统各项性能参数达到设计指标。 关键词：声音导引、无线收发、声源移动、M 智能语音小车-Abstract: The guidance system consists of the sound systems and car audio guidance master control system composed of two parts. Sound-guided mainly by the main control system master MCU, the sound receiving part, the wireless transmitter module component. Vehicle control system mainly consists of MCU, curing module NEC, motor drive parts, sound and light parts and the wireless receiver module. The most prominent feature of the system software designed for use in its hierarchical, modular design approach, the system low-power, low cost. The debugging and testing, system performance parameters to achieve the design target. Key words: sound guidance, wireless transceiver, a sound source movement, MCU, NEC, motor drive
