Definitions

  • the present invention relates to techniques for transmitting data and can be applied in various fields of national economy.
  • Radio frequency (RFID) sensors for various purposes are widely known.
  • RFID Radio frequency
  • an RFID sensor is provided that stores information from various types of sensors (temperature, short-circuit, etc.) in the memory of the transponder chip, and then the radio frequency reader receives this data.
  • the disadvantage of this solution is the need to save data in the memory of the chip.
  • the present invention is the development of such a radio frequency sensor, with which you can remotely wirelessly determine the status of the sensor (s) without storing the state of the sensor in the memory of the radio frequency chip.
  • a radio frequency sensor comprising a radio frequency chip; an antenna; an environmental parameter sensor whose state changes the response signal of the radio frequency microcircuit, perceived by the radio frequency reader; characterized in that the sensor changes its shape due to a change in the environmental parameter, and the change in the response signal occurs due to the approach or removing part of the sensor to the antenna or microcircuit, or destroying the sensor of the antenna, microcircuit, or the connection between them.
  • the sensor may comprise a bimetallic element, a swellable element, or a liquid that expands as a result of freezing.
  • a change in the response signal occurs due to the approach or removal of the metal located on the sensor to the antenna.
  • a change in the response signal occurs due to a change in at least one electrical characteristic of the antenna caused by the electrical contact of the sensor portion and said antenna.
  • the senor changes the response signal after one of its parts has increased its size, and then reduced it.
  • the senor can change appearance when the environmental parameter changes.
  • FIG. Figure 1 shows an example implementation of a sensor with a liquid expanding upon freezing.
  • FIG. Figure 2 shows an example implementation of a sensor when it changes the response signal after one of its parts has increased its size, and then reduced it.
  • the sensor of the present invention can be implemented in several versions, which, however, are implemented in a similar way.
  • RFID tags can be applied. Their thickness is measured in microns.
  • the working element of the sensor can be a bimetallic plate, a swellable substance or an aqueous solution of salt.
  • RFID radio frequency
  • a bimetallic plate can be used as a sensor. It can be installed so that when a certain temperature is reached, an electrical contact occurs between the conductive plate and the antenna tag. Since the characteristics of the antenna will change at the moment of touching, the RSSI will change, or the label will become inaccessible for reading.
  • water or a swellable substance with a conductor can also be used.
  • FIG. 1 This sensor is a rigid plastic cylinder 1, most of which is filled with a liquid 2 expanding during freezing: water or saline water.
  • the cylinder has a piston 3 or a flexible membrane to which a metal needle 4 is attached. When water 2 freezes, it expands and moves the piston 3 down.
  • the sensor of FIG. 2 Its body 1 is also made of hard plastic, and the piston 3 is held by beveled protrusions 5, dividing the sensor into two sections.
  • the piston 3 is connected by an uncompressed spring 6 with the plate 7, on which the needle 4 or the blade is located.
  • the spring 6 will be compressed, since the lower water 2 will also freeze and will not allow the plate 7. to move. After the water 2 has melted, the spring will be unclenched , and the needle 4 will destroy, for example, the junction of the antenna and the chip.

Abstract

L’invention concerne des équipements de communication. Son utilisation permet de déterminer l’état d’un capteur par un procédé utilisant des radiofréquences sans devoir mémoriser l’état du capteur dans la mémoire d’une puce à radiofréquence. L’intensité du signal de réponse d’une étiquette RFID est modifiée suite au rapprochement d’une partie du capteur qui change de taille sous l’effet de variation d’un paramètre environnemental (élément bimétallique, élément gonflant ou liquide se dilatant sous l’effet du gel) de façon à se rapprocher d’une étiquette RFID standard. Lors du rapprochement d’un capteur l’étiquette se détruit ou les caractéristiques de son antenne changent.
