Temperature measurement method and device based on RFID chip, temperature measurement system and storage medium

Abstract

The invention discloses a temperature measurement method and device based on an RFID chip, a temperature measurement system and a storage medium wherein the temperature measurement method based on a passive ultrahigh-frequency RFID chip comprises the following steps: after establishing a communication connection with the passive ultrahigh-frequency RFID chip, reading memory data of the passive ultrahigh-frequency RFID chip; determining the relationship between the reverse link frequency of the passive ultrahigh frequency RFID chip and the temperature; and obtaining the current reverse link frequency of the passive ultrahigh frequency RFID chip, and determining the temperature value of the passive ultrahigh frequency RFID chip according to the relation and the current reverse link frequency. Therefore, the temperature measurement method based on the passive ultrahigh frequency RFID chip can be compatible with various temperature measurement environments, the detection method is simple and sensitive, the temperature measurement cost can be reduced, and the working efficiency and the user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of temperature detection, in particular to a temperature measurement method based on a passive UHF RFID (Radio Frequency Identification, radio frequency identification) chip, a computer-readable storage medium, a temperature measurement system and a A temperature measuring device based on a passive UHF RFID chip. Background technique [0002] Temperature detection can be applied in all walks of life. Among the temperature detection methods adopted, they can be divided into active measurement and passive measurement according to whether an external power supply is required. [0003] In related technologies, most temperature measurements are active, including most RFID chips with temperature measurement functions that also use active or semi-active working methods. Active devices need battery power, and the cost of finished products is relatively high. , and the battery needs to be replaced regularly,...

Problems solved by technology

[0003] In related technologies, most temperature measurements are active, including most RFID chips with temperature measurement functions that also use active or semi-active working methods. Active devices require battery power, and the cost of finished products is relatively high. , and the battery needs to be replaced regularly, regular maintenance is required, a small number of passive RFID chips with a temperature sensing module, because the temperature sensor increases the power consumption of the chip, the sensitivity becomes lower, and the working distance becomes shorter, which greatly reduces its usage scenarios
