Problems solved by technology

[0003] During the research and practice of the prior art, the inventors of the present invention found that although the thermal connection is adopted between the infrared sensor and the window, there is still a temperature difference between the infrared sensor and the window, so that the infrared radiation of the window cannot be eliminated. Influenced by radiation, and the transmittance of the window is limited, it is impossible to allow the infrared radiation to completely pass through the window, thus affecting the signal strength generated by the infrared sensor through the detection of infrared radiation, resulting in poor measurement accuracy of the infrared ear thermometer high

Abstract

The invention provides an infrared ear thermometer. A probe of the infrared ear thermometer comprises a temperature sensor which is used for sensing the temperature of a window piece and is connected with the window piece in a heat conducting way. The infrared ear thermometer comprises a controller, wherein the controller comprises an acquisition module which is used for acquiring an output signal of the temperature sensor and a processing module which is used for modifying an output signal of an infrared sensor according to the output signal of the temperature sensor and processing the modified output signal to acquire a target temperature to be detected; and the acquisition module is connected with a signal output end of the temperature sensor. In the embodiment of the invention, a detection result of the infrared sensor can be modified according to a detection result of the temperature sensor in the temperature of the window piece so as to acquire an accurate body temperature and improve the accuracy of the infrared ear thermometer.

Description

technical field [0001] The invention relates to the technical field of temperature measurement, in particular to an infrared ear thermometer and a temperature measuring method of the infrared ear thermometer. Background technique [0002] Infrared ear thermometer is a non-contact telemetry body temperature measuring instrument. Usually, in order to waterproof or prevent dust and debris from entering the filter of the infrared sensor, the front end of the probe of the infrared ear thermometer corresponds to the position of the infrared sensor in the probe. , generally a window with high transmittance is designed, the window can isolate the infrared sensor from the external environment to ensure the accuracy of the infrared sensor, and there is a good thermal connection between the window and the infrared sensor, so that the infrared The sensor can detect the infrared radiation sent by the eardrum through the window to complete the measurement of body temperature. [0003] Du...
