Technical field
This utility model relates to a kind of electronic measuring instrument, specifically refers to a kind of low power-consumption intelligent clinical thermometer based on NFC.
Background technology
At present, the measurement of bldy temperature instrument on market mainly contains two kinds, and a kind of is traditional mercurial thermometer, and another kind is electronic clinical thermometer.Although traditional mercurial thermometer Applicative time is longer, it exists measures the defects such as inconvenient, frangible, Measuring Time is longer, is not easy to long-time continuous temperature monitoring.Though and electronic clinical thermometer is convenient to detect, one of its core requirement will have low power capabilities exactly, to make product practical.In order to realize low-power consumption, just requiring that electronic clinical thermometer will enter low power consumpting state in non-measured state, entering the higher measuring state of power consumption when there being measurement demand again.Whether have measurement demand for detecting, traditional method is all that when button is not pressed, body temperature counts low power consumpting state, when button is pressed, then can wake electronic clinical thermometer up and enter measuring state for electronic clinical thermometer increases button.Reduce power consumption in this way although adopt, add the frame for movement of electronic clinical thermometer, when especially using mechanical key, carry out special structural design again to realize the water-proof function of clinical thermometer.Therefore, traditional mechanical push-key type electronic clinical thermometer is not well positioned to meet structure demand that is simple, effectively waterproof.
Utility model content
The purpose of this utility model is to overcome the not good defect of complex structure existing for current electronic clinical thermometer, waterproof effect, provides a kind of low power-consumption intelligent clinical thermometer based on NFC.
The purpose of this utility model is achieved through the following technical solutions: based on the low power-consumption intelligent clinical thermometer of NFC, primarily of main control chip, the signal acquisition circuit be connected with this main control chip and NFC module, and the power supply be connected with main control chip, signal acquisition circuit and NFC module respectively forms.
Further, described main control chip is the one chip microcomputer with low power consumption characteristic, and it preferentially adopts CC2540 single-chip microcomputer to realize.It is by Power supply, the on/off of other functional circuit of management and control and duty, and to reduce power consumption, main control chip processes the signal that other functional circuit produces simultaneously.
Described signaling conversion circuit by temperature sensor R8, and forms with the divider resistance R5 that this temperature sensor R8 is in series; And described signal amplification circuit is by difference amplifier U2, the voltage follower U1 be connected with difference amplifier U2 and voltage follower U3 forms; Described voltage follower U3 is connected with signaling conversion circuit.
Described NFC module is the contact type intelligent card module meeting ISO14443 standard, and it preferentially adopts SWM1703 type to realize.When near mobile phone, NFC module and mobile phone carry out data communication, obtain thermometric enabling signal, and by this signal transmission to main control chip, thus start temperature survey.
This utility model comparatively prior art is compared and is had the following advantages and beneficial effect:
(1) this utility model overall structure is very simple, when not increasing electronic thermometer structure complicated process and waterproof difficulty, can realize the low power capabilities of clinical thermometer.
(2) this utility model has and combines RFID radio-frequency technique, NFC technology and low-power chip, thus achieve without button design, electronic clinical thermometer is waken up by the communication function of NFC module, the energy consumption of electronic clinical thermometer can not only be reduced significantly, and its structure can also be simplified, strengthen its waterproof ability.
