摘要
在完善无线测温系统方面,测温采集单位的电源需要一种能够长期使用、节能高效的方式,需要从有源到无源的转变。针对这个问题提出一种无源无线的解决方案。通过分析声表面波谐振器的传感原理和传统传感系统的构成,采用一次变频的构成方式,在声表面波谐振器的原理基础上建立无源无线温度传感系统,并引入了计算机控制和数字信号处理技术。
In perfecting the wireless temperature measuring system, the power of the temperature acquisition unit needs a long-term use, energy saving and efficient way, and it should be transferred from active to passive. Aimed at this problem, we put for-ward a kind of passive wireless solutions. Through the analysis of the sensing principle of surface acoustic wave resonator and com-position of traditional sensing system, a passive wireless temperature sensing system is constructed based on surface acoustic waveresonator. The system adopts the opposition of a frequency conversion method, and introduces the computer control and digital sig-nal processing technology.
