本文提出了一种简单，低成本的解决方案，用于实现基于超高频（UHF）射频识别（RFID）无源标签的螺钉松弛传感器。所提出的方法机会性地使用金属螺钉（或固定在塑料螺钉上的金属部件）的自然能力来实现两条电线之间的电连续性，这被利用来实现与拧紧/松弛螺钉状态相关联的打开/闭合开关机构。根据不同的工作环境和情况，以及标签传感器的实现方案，几个开关式的可能实现的描述。三个标签传感器的设计和制造符合金属或非金属应用表面，并在UHF RFID中国频段920.5 - 924.5 MHz内工作，显示出可靠的区分拧紧和放松螺钉状态的能力。最后，如最大检测表面和最小检测时间的参数进行评估，完成所提出的检测系统的分析。
This paper presents a simple and low cost solution for the implementation of a screw relaxing sensor based on ultra-high frequency (UHF) radio frequency identification (RFID) passive tags. The proposed method opportunistically uses the natural capability of a metallic screw (or a metallic part fixed on a plastic screw) to realize an electrical continuity between two electrical lines, which is exploited to realize an open/closed switch mechanism associated to the tightened/relaxed screw status. Several switch-like possible realizations are described according to different working environments and situations, as well as tag-sensor implementation schemes. Three tag-sensors are designed and manufactured to comply with metallic or non-metallic application surfaces and to work within the UHF RFID Chinese band 920.5 - 924.5 MHz, showing a reliable discrimination capability between well-tightened and relaxed screw states. Finally, parameters such as maximum detection surface and minimum detection time are evaluated for completing the analysis of the presented detection system.
