摘要

为了实现超声波手势识别功能来改善人机交互的体验

设计了一个用于手势识别的超声波收发器嵌入式系统

包括前端的发射器驱动电路和接收器信号采集电路设计、可编程片上系统(System on a Programmable Chip

SOPC) 硬件电路设计以及相应的软件设计.实验结果证明该系统的软硬件实现方案可以正确控制超声波的发射、接收以及后续的数据传输

同时确保发射和接收之间的相位同步

最终在PC端获得完好的回波信号.

Abstract

A ultrasonic transceiver embedded system for gesture recognition is designed to realize ultrasonic gesture recognition for improving the user experience.The system includes front-end drive circuits design of the transmitter

signal acquisition circuits design of the receiver

SOPChardware circuit design and software design accordingly.The experimental results show that the emission

reception and subsequent data transmission of ultrasonic can be controlled correctly by the hardware and software implementation scheme of the system.Meanwhile

the phase synchronization between emission and reception is also ensured.Finally

the intact gesture echo signal is obtained at the PC side.
