(4) The temperature sensor senses the temperature of a human body, generates a current or voltage signal proportional to the temperature and transmits the current or voltage signal to the signal conditioning module.
(5) The signal conditioning module converts the current or voltage signal into a frequency signal and a digital signal in sequence and sends the digital signal to the RFID chip.
(6) And the RFID chip sends the digital signal to the mobile phone with the NFC function through the built-in antenna.
(7) And displaying the received temperature value in the mobile phone APP.
Furthermore, before the passive RFID temperature tags are used, calibration is needed (when the wireless terminal adopts an RFID reader-writer, calibration of a plurality of intelligent mask passive RFID temperature tags can be completed each time; when the wireless terminal adopts an NFC mobile phone, calibration of only 1 intelligent mask passive RFID temperature tag can be completed each time).
The calibration and calibration steps are as follows:
(1) the passive RFID temperature tag of the standard temperature measuring instrument and the intelligent mask to be calibrated are placed in the same temperature environment.
(2) And (3) enabling the RFID reader-writer or the NFC mobile phone to be close to the passive RFID temperature tag, and enabling the application software to send a calibration instruction to the RFID chip.
(3) The RFID chip transmits the measured temperature value and the current calibration coefficient of the temperature sensor back to the RFID reader-writer or the mobile phone with the NFC function.
(4) And the RFID reader-writer or the NFC mobile phone acquires data and compares the data with the temperature value displayed by the standard temperature measuring instrument to obtain a new calibration coefficient.
(5) And the RFID reader-writer or the NFC mobile phone sends the new calibration coefficient to the RFID chip to complete calibration.
The beneficial effect of this embodiment lies in: adopt the NFC function of cell-phone, can let intelligent gauze mask person of wearing monitor self body temperature at any time, and because cell-phone NFC antenna receiving and dispatching power is less, can only receive closely (less than or equal to 10cm) intelligent gauze mask's temperature information, can not receive other people's information by mistake.
To sum up, the utility model provides an intelligent mask adopts the one-way mode of admitting air, namely adopted the check valve, utilize the diaphragm capsule to produce the principle that stretches out and draws back under the effect of inside and outside atmospheric pressure difference and self elasticity power, the compactness of wearing of automatic monitoring mask, and combine suggestion device, when the diaphragm capsule gas tightness is not good, LED lamp and power supply mechanism circular telegram and give out light, remind the user to carry out the adjustment of diaphragm capsule, and then can ensure that the protective effect of diaphragm capsule is given full play, the gas of exhalation gets into the diaphragm capsule, the diaphragm capsule is not communicated with outside atmosphere, guaranteed that the gas of exhalation can not directly get into the atmosphere, prevent effectively that the gas of exhalation from polluting other people; when the radio frequency reader-writer is adopted, signals of a plurality of passive RFID temperature tags can be read simultaneously, abnormal body temperature can be warned in time, the monitoring efficiency is high, and the radio frequency reader-writer is particularly suitable for rapidly monitoring the body temperature of staff in real time during epidemic situations in enterprises and public institutions such as factories, schools, hospitals and the like; the passive RFID temperature tag is adopted, a power supply does not need to be additionally configured, the radio frequency and data reading functions of a mobile phone NFC function or a radio frequency reader-writer are fully utilized, when the mobile phone NFC or the radio frequency reader-writer is close to the passive RFID temperature tag, the passive RFID temperature tag obtains energy through electromagnetic induction and is activated, direct current voltage is established, passive power supply is achieved, the installation of a battery is avoided, and the space is saved.
The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
