Embodiment Construction

[0014] figure 1 It is a structural schematic diagram of a passive wireless sensor used for power switch cabinet contacts and temperature measurement. The shell (1) used as a support material is made of hollow special engineering plastics, which is semi-circular in shape, with an inner diameter of about 50mm and a thickness of 10mm, and can be adapted to measure temperature with a cylindrical contact of 28-90mm. Antenna (8) and temperature sensor board (6) can be installed and fixed from the narrow and long opening on the inner side, and then paste copper foil (2) on the inner side as a reference ground, copper foil (2) and temperature sensor board (6 ) is in good contact with the reference ground. In order to increase the flexibility, the two ends of the hollow supporting material are open holes, and a silicone plug (3) needs to be installed for sealing. There are two structures on the housing (1) for fixing the sensor: one is the groove (4) on the side of the housing, which...

Abstract

The invention proposes a flexible ultrathin anti-metal passive wireless sensor, and the sensor is advantageous in that the sensor can be deformed, is resistant to metal, is suitable for surfaces in different shapes, is good in signal coverage, and is ultrathin. The sensor is characterized in that the sensor consists of a wireless energy-fetching type sensing chip, an antenna, and a flexible supporting material; the antenna is a metal belt or a metal film which is designed according to the working frequency and has a certain figure structure; the thickness and length of the flexible supporting material are determined according to the requirements of the performance of the antenna, and remains unchanged when the sensor is bent and deformed. The sensor can be fixed on a measured object in different modes. The supporting material can be selected from silicone rubber, gold, engineering plastics for a bridge pier structure, or hollow engineering plastics.

Description

technical field [0001] The invention relates to the field of wireless sensors, in particular to a metal surface, ultra-thin passive wireless sensor and a realization method thereof. Background technique [0002] Passive wireless sensors refer to sensors that do not require power supply and can be read wirelessly. Currently, surface acoustic wave sensing technology can achieve this feature. The unique advantages of passive wireless make this type of sensor very suitable for applications such as temperature measurement of power switch cabinets. However, since the working energy comes from the electromagnetic waves emitted by the reader, passive wireless sensors also have the disadvantages of weak signal and sensitivity to installation location. For high-voltage power switchgear, the moving and static contacts are the parts most in need of temperature monitoring, but the contacts are cylindrical metal structures with different diameters, and are installed in the contact box wi...
