摘要
本系统以TI公司的超低功耗MCU MSP430处理器为核心,CPU(MSP430)根据声音接收模块的信号到来的时间不同能迅速获取信号,由接收模块的位置不同所接收到信号的时间不同,根据时间差可得到声源距接收模块的距离差。整个系统可实现误差信号的产生,声源的定位,并有LCD显示,位于声音接收器上的声音接收模块接收声波,通过时差计算确定声源坐标。
The proposed system utilizes the low power consumption MCU MSP430 processor produced by TI company as the core. According to the arrival time of signal of voice receiving module, CPU MSP430 processor can quickly get signal. Ac- cording to the position of the receiving module, different received signals are get at different times. Based on the time lag, the difference of distance from the sound source to the receiving module is obtained. The whole system can realize error signal genera- tion, localization of sound sources, and LCD display. The sound receiving module installed on the sound receiver can receive sound waves, and the calculation of the time lag determines source coordinates.
