使用两个继电器开关用于多功能LC无源无线传感器系统
发布时间：2020-12-22 02:40
随着科学技术的发展,能够同时检测多个参数的传感网络的需求越来越多。LC无源无线多功能传感器系统作为一种植入式装置,在大规模食品质量的检测等领域具有诸多的应用。同时LC无源无线多功能传感器系统与传统的分立传感器相比,具有检测系统简单、成本低、尺寸小的优势。本论文提出了一种基于双继电器开关的多功能LC无源无线传感系统,并对提出的LC无源无线传感系统进行建模、仿真和实验验证,最终系统输出多个谐振频率的信号,表明系统具有同时测量多个参数的功能。本论文提出的LC型无源无线传感系统通过两个开关控制三个不同的电容式传感器,从而达到同时检测三个参数的目的。传感系统包括电感线圈、三个电容和两个开关。传感器线圈顺序并联三个不同的电容,其间依次串联两个开关,从而构成三个不同的LC谐振电路。读取线圈与传感器线圈通过磁耦合,以无线方式访问传感器并感应出电压,从而控制两个开关。本论文使用ADS软件对该LC传感系统进行建模和仿真,软件中使用三个独立的模块分别表示压力传感器、相对湿度传感器和温度传感器所对应的三种不同的谐振频率,并设置两个工作在不同阈值上电磁继电器开关,从而该LC传感系统的三个电容传感器能够同时测量三...
