Temperature measurement bracelet based on RFID temperature measurement label and temperature measurement system

Abstract

The invention discloses a temperature measuring bracelet based on an RFID temperature measuring tag and a temperature measuring system, the temperature measuring bracelet comprises the RFID temperature measuring tag, a dial plate, a watchband and a temperature sensing metal contact, the watchband and the two sides of the dial plate are connected to form a ring shape so as to be worn on the wrist of a human body. The RFID temperature measurement tag comprises a middle part provided with a temperature sensing chip and two wing parts provided with microstrip antennas, the temperature sensing chip comprises a temperature measurement module and an RFID communication module, the middle part of the RFID temperature measurement tag is embedded in the dial plate, and the two wing parts of the RFID temperature measurement tag are led out from the two sides of the dial plate and tilt in a wing shape; a through hole is formed in the side, attached to the skin, of the dial plate, one face of the temperature sensing metal contact piece is attached to the face, provided with the temperature sensing chip, of the RFID temperature measurement label, and the other face of the temperature sensing metal contact piece is exposed in the through hole of the dial plate and used for sensing the skin temperature. The temperature measuring bracelet meets the requirement for long-distance non-contact and non-perception temperature measurement, and therefore continuous temperature monitoring is achieved.

Description

technical field [0001] The invention relates to the technical field of wireless temperature measurement, in particular to a temperature measurement bracelet and a temperature measurement system based on an RFID temperature measurement tag. Background technique [0002] The invention patent with the patent number CN204813820U discloses an intelligent temperature measuring watchband, which includes a watchband, an NFC temperature tag and an MCU chip which are arranged in the watchband and electrically connected together. When in use, it is worn on the wrist, and the temperature data is automatically measured and saved according to the set interval. The set time interval can be changed with the NFC mobile phone. When collecting data, use the NFC mobile phone to approach the NFC tag on the strap to collect the required temperature data, etc., so that no manual input is required. However, due to the skin's absorption of wireless signals, the smart temperature measurement strap c...

Problems solved by technology

However, due to the skin's absorption of wireless signals, the smart temperature measurement strap can only meet the measurement of short distances (less than 10 cm), and cannot meet the application requirements of long-distance (greater than 1 meter) non-contact and non-perceptual temperature measurement

At the same time, the smart temperature measuring strap is powered by batteries, and the production process is more complicated and the cost is higher.
