摘　　要：针对传统声表面波无线标签接收方法标签接收率较低问题,提出基于物联网技术的声表面波无线标签接收方法设计。采用动态帧时隙算法对声表面波无线标签的数量进行估算,识别出接收范围内的声表面波无线标签,根据脉冲时延对无线标签进行定位,并利用物联网技术搭建无线标签接收端通信网关,实现对声表面波无线标签的接收。实验证明,所提方法的无线标签接收率高于传统方法,可以实现对声表面波无线标签的全面接收。Aiming at the low tag acceptance rate of the traditional surface acoustic wave wireless tag receiving method, a design of the surface acoustic wave wireless tag receiving method based on the Internet of Things technology is proposed. The dynamic frame time slot algorithm estimates the number of surface acoustic wave wireless tags, identifies the surface acoustic wave wireless tags within the receiving range, locates the wireless tags according to the pulse delay, and uses the Internet of Things technology to build a wireless tag receiver communication gateway, realizes the reception of surface acoustic wave wireless tags. Experiments have shown that the design method has a higher receiving rate of wireless tags than traditional methods, and can fully receive surface acoustic wave wireless tags.
