Cable temperature measuring device and method based on RFID chip

The invention provides a cable temperature measurement device and method based on an RFID chip, and the device specifically comprises a temperature measurement RFID tag chip and an RFID read-write device which are embedded in a cable, and the temperature measurement RFID tag chip comprises a radio frequency front end unit and a temperature sensor unit which are connected through a signal; the radio frequency front end unit is used for receiving a temperature measurement instruction of the RFID read-write equipment so as to trigger a temperature measurement function of the temperature sensor unit and feeding back temperature data of the temperature sensor unit to the RFID read-write equipment; and the temperature sensor unit comprises a sensor analog front-end circuit and an ADC module, and is used for giving temperature data based on the VBE of the triode under the bias current and sending the temperature data to the radio frequency front-end unit. A proper radio frequency front end unit is arranged, stable w
