| 本设计采用多机系统结构完成了声音引导系统的硬件和软件设计。系统下位机采用两片STC12C5A60S2增强型51单片机，一片用于控制双直流电机双轮驱动小车，并发出声光信号；另一片检测三个不同位置的声音传感器信号，根据三个位置接受到的声音信号时间不同，计算出小车离各个接收点的距离，确认移动声源的位置，决策小车的运动轨迹。两片单片机采用无线通信的方式进行通信。上位机同步显示声源小车的运行状态。直流驱动电路采用高效的L293D，有利于提高电源利用率。通过测试三位置声音到达时间差的方式实现声源的定位。 |

| Hardware and software of voice guidance system design is complete by using Multi-motor system structure in this design . The lower control system use two piece STC12C5A60S2 enhanced 51 single-chip computer. One piece used to control the dual DC motor wheel drive car, and give out sound and light signals; another test three different positions of voice sensor signal . According to the voice signals received of three positions at different times, calculate the distance between car and each receiver point, confirm the position of moving sound, determine the car's trajectory. Two piece single-chip computer communicate by wireless communication means. Upper machine shows the car running synchronous. DC driver circuit using effective L293D, help improve power utilization. By testing the different time of sound arrival of the three positions to achieve the localization of their sources. |

| The hardware and software designing of voice guidance system is based on the multi-computer system. Dual-piece STC12C5A60S2 strengthened 51 single-chip computer was utilized as the lower computer. One piece was used to control the dual DC motor and wheel driven car, giving out sound and light signals. Another was utilized to test different voice sensor signals from three positions. According to the difference in the received time of the voice signals, the distance between car and each received positions could be calculated, confirming the position of the moving sound source, and thus the track of the car was determined. Double piece single-chip computers were kept in touch with each other by the mean of wireless communication. The running behavior of the sounded car could be tracked with the up computer at same time. High efficient L293D was driven by DC circuit, improving the utilization efficiency of the power. The localization of the sound source could be achieved by comparing the different time of the sound arrival from the three positions. |
