Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In specific implementation, the control terminal described in the embodiment of the present invention and controlled terminal can comprise: smart mobile phone, panel computer etc., and above-mentioned terminal is only citing, and non exhaustive, including but not limited to above-mentioned terminal.
The thermometry provided the embodiment of the present invention below in conjunction with Fig. 1 to Fig. 5 and terminal are specifically described.
Please refer to Fig. 1, is the first embodiment schematic flow sheet of the thermometry that the embodiment of the present invention provides.The thermometry of the embodiment of the present invention comprises step:
S100, when adopting terminal to carry out infrared measurement of temperature, judges whether there is object in described terminal preset range;
In specific embodiment, terminal comprises infrared temperature sensor and temperature compensation module, and infrared temperature sensor mainly utilizes infrared radiation thermal effect, causes temperature to raise, thus measure the temperature value of certain limit after receiving the heat radiation of object and human body.The physical essence of infrared radiation is heat radiation, and the temperature of object is higher, and the infrared ray radiated is more, and the energy of infrared radiation is stronger.Infrared temperature sensor utilizes thermal effect of radiation, the sensitive detection parts received radiation in sensor can after cause temperature to raise, make to change with the performance of temperature correlation in infrared temperature sensor, thus measure the temperature value of certain limit.
Temperature compensation module in terminal is mainly used in the temperature compensation of body temperature and extraneous measuring tempeature, and the general temperature error compensation scope according to measuring object carries out error compensation, promotes the accuracy of temperature.Such as, but usually different measuring objects, the scope of temperature compensation is different, and, medically the error range of body temperature is at+-2 degree, if reach 3 ~ 5 degree just do not meet medical prescription.And general environment temperature error range all+-5 degree.So, if compensate the measurement of body temperature with the temperature model of measurement environment, the error of temperature will be made to become large.
Therefore, when adopting terminal to carry out infrared measurement of temperature, what need specifically to judge premeasuring is environment temperature, or object temperature, thus adopts different offset rules to carry out temperature compensation.In the present embodiment, first judge whether there is object in terminal preset range, usual preset range is that the infrared temperature measurement apparatus of terminal is launched within ultrared scope, concrete optional, judgment mode can be, infrared temperature measurement apparatus is utilized to launch infrared ray in preset range, if there is object in preset range, can reflect after then this object receives the infrared ray of infrared temperature measurement apparatus, it should be noted that, the infrared energy that infrared temperature measurement apparatus is launched is far longer than object self infrared energy.
