Temperature-measurable radio-frequency tags and navigation aids equipped with the tags

Abstract

The invention discloses a temperature-measuring radio frequency tag and a navigation aid lamp equipped with the tag. The temperature-measurable radio frequency tag includes a surface acoustic wave radio frequency tag chip and a tag antenna; the surface acoustic wave radio frequency tag chip includes a piezoelectric substrate, an interdigital transducer and a reflection grid; the reflection grid includes a temperature measurement reflection grid and a Coded reflective grating; the interdigital transducer and the reflective grating are located on the piezoelectric substrate. Aids to navigation may be runway edge lights, taxiway edge lights or runway center line lights. The invention ensures reliable reading of the tags in the internal environment of the navigation aid lamps, realizes the integration of special radio frequency tags in the navigation aid lamps, and makes it possible for the practical application of the Internet of Things technology in the spot inspection of the navigation aid lamps. Improve efficiency and improve management effectiveness.

Description

technical field [0001] The invention relates to the field of the Internet of Things and radio frequency identification, in particular to a temperature-measurable radio frequency tag used for airport navigation lamps and a navigation lamp equipped with the tag. Background technique [0002] At present, China's aviation, especially the airport construction, is in a period of rapid development. The increasingly strong transportation demand makes the airport have to add more runways, and the flight departures and landings are becoming more and more frequent. The airport navigation aid lighting system is a necessary visual aid to ensure the normal takeoff, landing and taxiing of the aircraft at night, low visibility or other complex weather conditions. According to the relevant regulations of the Civil Aviation Administration of China, it is strictly forbidden for three consecutive navigation lights to be damaged (not lit), otherwise it will be regarded as a serious safety accide...
