Technical Field

The invention relates to the technical field of electronic temperature measurement, in particular to a wireless charging infant body temperature monitoring device and a wireless charging method.

Background

The body temperature of the infants is monitored at any time so as to timely cool the infants or seek medical advice. Especially, infants who have repeated fever or have a history of convulsion work for one day in the daytime, and also need to keep the children who have repeated fever continuously at night, are afraid of not being treated in time after the body temperature exceeds 38.5 ℃, and are afraid of the high fever condition with the body temperature above 39 ℃ and dehydration or convulsion.

In the prior art, similar electronic thermometers generally adopt RC (resistive temperature coefficient) for temperature measurement, and since the requirements of a thermistor R (NTC or PTC) and a dielectric capacitor C on the environment are high, the measurement accuracy cannot be guaranteed, for example, the temperature measurement effect of the scheme is influenced in dry or high-humidity environments, cold winter low-temperature environments, hot summer high-temperature environments, infant systems and the like.

Although some technical schemes adopt a double temperature measuring circuit matched with a temperature compensation algorithm, the following conditions still cannot be met: 1. the temperature values measured by the components are different if a capacitor or a resistor is used; 2. the difference in circuit design, if some thermistor and extension line are needed to extend, the extension line is usually a metal wire, the length of each extension line has slight difference, the resistance value of the resistor has slight difference, the diameter of each extension line has slight difference, and the resistance value of the resistor also has slight difference; 3. the dual temperature measurement needs to use two temperature measurement ports of the CPU, two different PCB circuits and the difference of the resistance values of the PCB circuits; the differences form the problems that the measurement on the user evaluation of a certain intelligent thermometer in a certain treasure and a certain east is inaccurate (the error range is too large), the connection is easily interrupted or not connected in the Bluetooth, the operation is complex, the measurement accuracy is low and the like.

The existing electronic temperature detectors also have the technical problem that batteries need to be replaced and/or charging is inconvenient.
