1. Field of the Invention
The present invention relates to a method for detecting body temperature of a live body, particularly to a method for fast detecting body temperature of a live body.
2. Description of the Related Art
Temperature is an important physiological index indicating whether a living body is healthy. The instruments for temperature measurement can be categorized into the contact thermometers and the non-contact thermometers. The contact thermometers include mercury thermometers and electronic thermometers. The non-contact thermometers include infrared thermometers, such as infrared ear thermometers, infrared forehead thermometers, and infrared ear-forehead thermometers. The infrared thermometers are getting more and more popular because they are easy to operate and prompt to output results.
The infrared ear thermometer is not always suitable to the persons having some ear defect or sleeping children. Contrarily, the infrared forehead thermometer can work in the abovementioned cases. A U.S. Pat. No. 6,292,685 disclosed an infrared forehead thermometer, wherein the probe of the infrared thermometer is used to scan the testee's forehead to obtain a plurality of measurement values, and the greatest one of the measurement values is converted into a forehead temperature. However, the greatest measurement value usually contains noise. Thus, the test result is likely inaccurate. Besides, the conventional infrared forehead thermometer has to convert each measured infrared signal into a forehead temperature immediately. Thus, the scanning speed thereof is reduced, and the accuracy thereof is decreased.
Accordingly, the present invention proposes another method for detecting body temperature of a live body to overcome the abovementioned problems.
One objective of the present invention is to provide a method for detecting body temperature of a live body, which firstly obtains an average infrared signal from several infrared signals and converts the average infrared signal into a forehead temperature, and which outperforms the conventional technology that has to one by one convert infrared signals into temperature values and is hard to fast detect body temperature.
Another objective of the present invention is to provide a method for detecting body temperature of a live body, which can fast obtain a high-accuracy result in temperature measurement.
The method for detecting body temperature of a live body of the present invention comprises steps: scanning the forehead of a testee and receiving a plurality of infrared signals; sequencing the infrared signals to obtain the greatest infrared signal; selecting several infrared signals closest to the greatest infrared signal from the sequenced infrared signals; obtaining an average infrared signal of the selected infrared signals; and converting the average infrared signal into a forehead temperature.
Below, the technical contents of the present invention will be described in detail to enable the persons skilled in the art to easily understand the present invention.
It to be noted that the foregoing general description and the following detailed description are only intended to exemplify the present invention but not to limit the scope of the present invention.
The present invention proposes a method for detecting body temperature of a live body, which uses an infrared thermometer to fast detect the forehead temperature of a testee and obtain a more precise forehead temperature. Below, an infrared forehead thermometer is used as a measurement instrument to describe the technical contents of the present invention.

In conclusion, the method for detecting body temperature of a live body of the present invention sequences the received infrared signals, selects several appropriate infrared signals from the sequenced infrared signals, works out an average infrared signal from the selected infrared signals and converts the average infrared signal into a forehead temperature. The present invention can solve the problem of the conventional technology that has to convert all infrared signals into temperatures one by one and is hard to fast obtain the measurement results. The conventional technology adopts the highest temperature as the measurement output. The highest temperature is worked out from the greatest infrared signal. However, the greatest infrared signal contains a notable proportion of noise. The present invention does not adopt the greatest infrared signal but utilizes several infrared signals closest to the greatest infrared signal. Therefore, the present invention has a more precise measurement result.
The embodiments described above are to demonstrate the technical contents and characteristics of the present invention and to enable the persons skilled in the art to understand, make, and use the present invention. However, it is not intended to limit the scope of the present invention. Therefore, any equivalent modification or variation according to the spirit of the present invention is to be also included within the scope of the present invention.
