Problems solved by technology

[0005] The technical problem to be solved in the present invention is that due to the split design between the temperature measuring probe and the main body of the split thermometer and the individual differences between the temperature measuring probes, the accuracy of the split thermometer is relatively poor when used, and the temperature measurement is not accurate. In the case of a split-type thermometer, a temperature calibration method for a split-type thermometer is provided. Through the method of the present invention, the measurement accuracy of the split-type thermometer can be improved

Embodiment 1

[0026] This embodiment is a hardware embodiment of the split-type thermometer of the present invention.

[0027] The split-type thermometer includes a temperature measuring probe, a host and a connecting wire. The temperature measuring probe and the host are detachably connected by a circuit. The temperature measuring probe is provided with a temperature sensitive element. The temperature sensitive element used in this embodiment is the thermistor Rntc. A unique identification mark is set on the temperature measuring probe. The unique identification can be printed on the shell of the temperature measuring probe or engraved on the shell of the temperature measuring probe.

[0028] The host includes: MCU, power supply, temperature measurement module, data storage module and human-computer interaction module. The power supply is controlled by the power supply to supply power to the MCU, the MCU is connected to the human-computer interaction module, the MCU is connected to the tem...

Embodiment 2

[0032] This embodiment is an application embodiment of the calibration method of the present invention.

[0033] Calibration of the main unit:

[0034] The calibration of the host is the calibration of the voltage dividing resistors of the temperature measurement module. In practice, there is an error between the voltage dividing resistors and there is an internal resistance inside the ADC, so the host needs to be calibrated. The host calibration is carried out in the following ways: image 3 As shown, the high-precision, low-temperature drift resistor R is used to replace the temperature probe. By obtaining the voltage on the high-precision, low-temperature drift resistor R, the current flowing through the high-precision, low-temperature drift resistor R is calculated, and the high-precision, low-temperature drift resistor R is subtracted from VCC. The voltage on the low temperature drift resistor R, the voltage across the voltage divider resistor is obtained, and the voltag...

Abstract

Temperature calibration data of a temperature measurement probe is stored in a host, a unique identity label on the temperature measurement probe is input into the host before measurement and corresponds to the temperature calibration data of the temperature measurement probe on the host, and meanwhile, the internal resistance of a temperature measurement module of the host is calibrated, so that the temperature calibration data of the temperature measurement probe on the host is calibrated. And the measurement result is compensated, so that the measurement deviation of the split type thermometer is greatly improved. According to the method, the temperature measuring probe is simple in structure, accurate in temperature measurement and easy to implement, and the cost of the temperature measuring probe is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of split-type thermometers, in particular to a split-type thermometer and a calibration method thereof. Background technique [0002] Thermometers are widely used in hospital outpatient clinics and emergency departments. At present, integrated thermometers are commonly used. When integrated thermometers are used in hospital outpatient clinics and emergency departments, there are mixed use cases. With the improvement of people's hygiene awareness, a split thermometer was designed. [0003] The split thermometer generally includes a temperature measuring probe and a host. Due to the split design between the temperature measuring probe and the host, and the individual differences between the temperature measuring probes, the accuracy of the split thermometer in use is relatively poor and the temperature measurement is inaccurate. [0004] After searching, it was found that Chinese patent CN201220290559.9 disc...
