Temperature measuring probe and temperature measuring device

Abstract

The invention discloses a temperature measuring probe and a temperature measuring device and belongs to the temperature measurement field. The temperature measuring probe has the advantages of no need for batteries, small size, long service life and safe and convenient use, and supports temperature data transmission and management. The temperature measuring probe of the invention includes an antenna, a coupling element, a radio frequency identification chip and a temperature measurement circuit; the antenna is connected with a capacitor in the coupling element, so that a resonant circuit can be formed and is used for sensing electromagnetic waves emitted by an inductive reader, and storing acquired energy in the capacitor, and supplying power for the radio frequency identification chip; the radio frequency identification chip is connected with the antenna and the coupling element and is used for transmitting stored electronic tag information to the reader through the antenna; and the temperature measurement circuit is connected with the radio frequency identification chip and is used for detecting the temperature information of objects and transmitting the temperature information to the reader through the antenna.

Description

technical field [0001] The invention relates to the field of temperature measurement, in particular to a temperature measuring probe and a temperature measuring device. Background technique [0002] Temperature is a physical quantity that indicates the degree of coldness or heat of an object, and it is a parameter that is often used in production and life and needs to be measured. The temperature measurement tools that are currently used mainly include traditional mercury thermometers, infrared thermometers, and electronic thermometers based on temperature sensors. Mercury thermometers are inconvenient to use and poor in safety; infrared thermometers are large in size and do not have data management functions; existing electronic thermometers are also large in size, require battery power, and have a short service life. Small, safe and convenient temperature measuring device that supports temperature data transmission and management. Contents of the invention [0003] The...
