Description

TECHNICAL FIELD [0001] The present invention relates to a noncontact temperature meter calibrating system, and more particularly,

Embodiments of the present invention are directed to a non-contact temperature meter calibration system and method of performing the same.

In addition to a typical thermometer such as a mercury thermometer, an infrared thermometer capable of detecting the temperature of a given object based on the generated infrared radiation has recently been found to be widespread in the market.

In particular, an infrared thermometer includes a reading area for transmitting infrared rays emitted from a body region of a patient in which an infrared radiation sensor is operated to require heat detection to the sensor. Infrared thermometers available on the market today can be divided into two major classes, a partially invasive thermometer and a noninflammable thermometer.

In the first type of infrared thermometer, a thermometer part or a probe is inserted into the auricle of the object to be temperature-controlled so that the infrared radiation of this area is transmitted to the sensor element.

However, the thermometers just described above, although their value is generally valid, highlight some limitations related to the use of the thermometer itself under hygienic conditions, which involves the need for the use of a protective cap for the probe , And thermometer probes are not very practical in using them because they are annoying objects that are partially introduced into the patient's ear canal.

In a second type of infrared thermometer, a non-immersion thermometer, a thermometer end designed to deliver infrared radiation to the sensing element is provided to contact or stay away from the surface of the object whose thermal level should be known.

In order to accurately measure the temperature by using such an infrared thermometer, a great deal of attention is paid to the operation, and there is a problem that accurate measurement can not be performed unless the emissivity of the object to be measured is corrected.

The noncontact temperature measuring device calibration system of the present invention is a noncontact temperature measuring device calibrating a plurality of temperature measuring modules by simultaneously performing an error correcting process using a calibration module to shorten the calibration process time which is the most important and time- And an object of the present invention is to provide a method of executing the method.

According to the present invention, a plurality of temperature-measuring temperature-compensated modules are connected to the temperature-measuring-apparatus main module, and then the temperature-compensating error is checked. The noncontact temperature measuring module, which exceeds the error range, And a method of executing the calibration system.

The problems to be solved by the present invention are not limited to the above-mentioned problem (s), and another problem (s) not mentioned can be clearly understood by those skilled in the art from the following description.

Among the embodiments, the noncontact temperature measuring device correction system includes a plurality of temperature measuring modules including a temperature sensor for measuring a temperature of an object to be measured and a memory for storing a correction temperature of the temperature sensor, And a calibration module for determining a correction temperature for each of the temperature sensors and correcting temperature information of the temperature sensor for each of the sensors.

Among the embodiments, a method for implementing a non-contact temperature measuring system correction system includes connecting each of a plurality of temperature measurement modules to a calibration module, determining, for each of the plurality of temperature measurement modules, a correction temperature for the temperature sensor And the calibration module corrects temperature information for each of the temperature sensors of the plurality of temperature measurement modules using the correction temperature for the temperature sensor.

The details of other embodiments are included in the detailed description and the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and / or features of the present invention, and how to accomplish them, will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. It should be understood, however, that the invention is not limited to the disclosed embodiments, but is capable of many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

According to the present invention, an error correction process is simultaneously performed using a calibration module for a plurality of temperature measurement modules, thereby reducing the time of the calibration process that is the most important and time-consuming in the production of the non-contact temperature measurement device.

According to the present invention, a plurality of temperature-measuring temperature-compensated modules are connected to the temperature-measuring-apparatus main module, and then the temperature-compensating error is checked. The noncontact temperature measuring module, which exceeds the error range, Calibration process can be performed.

1 is a view for explaining a noncontact temperature measuring device calibration system according to an embodiment of the present invention.
2 is a view for explaining a process of checking a temperature correction error of a plurality of temperature measurement modules corrected through the noncontact temperature measuring device correction system according to an embodiment of the present invention.
3 is a flowchart for explaining an execution process of the noncontact temperature measuring device correction system according to an embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The noncontact temperature measuring device measures the body temperature by detecting the energy emitted by an object to be measured (for example, a human body), or more specifically, an infrared ray emitted by arterial blood flow with an infrared sensor.

In order to accurately measure the temperature using such a noncontact temperature measuring device, a great deal of attention is paid to the operation, and accurate measurement can not be performed without correcting the emissivity of the measurement object. Here, the emissivity means a rate at which energy is radiated from an object to be measured.

That is, it is a ratio of how much energy is emitted to the outside by an object to be measured having an energy of 100. For example, when the noncontact temperature measuring instrument measures the temperature of the object to be measured which emits the energy of 100 DEG C, 97 DEG C means that the object to be measured emits 97% of the energy. Therefore, in order to measure the actual temperature 100 캜 of the object to be measured, the portion corresponding to 3% should be corrected.

Conventionally, in order to correct the emissivity of the object to be measured for the above reasons, the error correction process is performed one by one using the calibration equipment. However, it takes a lot of time to carry out the error correction process for a large number of temperature measurement modules one by one.

In order to solve this problem, in the present invention, it is possible to shorten the time of the calibration process which is the most important and time-consuming in the production of the non-contact temperature measuring device by simultaneously performing the error correction process using the calibration module for a plurality of temperature measurement modules There are advantages.

In the present invention, a plurality of temperature-measuring temperature-compensated modules are connected to the temperature-measuring device main module, and the temperature-compensating errors are checked. If the temperature-measuring modules exceed the error-tolerance range, the temperature- .

That is, the calibration module 200 measures the temperature of the temperature sensor 101_1, 101_2, ..., 101_N of each of the plurality of temperature measurement modules 100_1, 100_2, ..., 100_N, And compares the standard temperature to determine the correction temperature for each temperature sensor.

In this manner, the calibration module 200 may include a plurality of temperature measurement modules 100_1, 100_2, ..., and 100_N to sequentially perform calibration setting on the temperature sensors 101_1, 101_2, ..., and 101_N of the plurality of temperature measurement modules 100_1, (100_1, 100_2, ..., 100_N) can be implemented as an experimental environment for measuring the experimental temperature of each temperature sensor.

In one embodiment, the calibration module 200 may be implemented with an absorber that does not cause radiation (e.g., a black body). In this way, the calibration module 200 can be realized as an absorber that does not cause radiation, so that the temperature sensors 101_1, 101_2, ..., 101_N of the plurality of temperature measurement modules 100_1, 100_2, ) Is measured.

In another embodiment, the calibration module 200 may be implemented with a temperature bath in which the temperature remains unchanged. In this way, the calibration module 200 implements the experiment on the temperature sensors 101_1, 101_2, ..., 101_N of the plurality of temperature measurement modules 100_1, 100_2, ..., 100_N under the assumption that the temperature does not change Measure the temperature.

Then, the calibration module 200 determines the correction temperature for each temperature sensor by comparing the experimental temperature and the standard temperature of the temperature sensor with respect to each of the plurality of temperature measurement modules, and supplies the correction temperature for each temperature sensor to a plurality of temperature measurement modules 100_1, 100_2, ..., 100_N).

In the present invention, it is possible to connect the plurality of temperature measurement modules 100 to the temperature meter main module 300 to check whether the correction temperature of the temperature sensor exceeds the error range, thereby selecting an object to be subjected to the temperature correction re-execution.

The temperature measurement module 100 includes a temperature sensor 101 for measuring the temperature of the object under the control of the temperature meter main module 300 and a memory 102 for storing the correction temperature for each temperature sensor. The reason for storing the correction temperature for each temperature sensor in the memory 102 is that when the temperature measurement module 100 is connected to the temperature measurement device main module 300 and the temperature of the measurement object is measured to generate the measurement temperature This is for use in calibrating the measurement temperature.

The temperature meter main module 300 includes a control section 301, a switch input section 302, a communication interface 303 and a display section 304.

The temperature sensor 101 measures the temperature of the measurement object And provides the control unit 301 with the measurement temperature generated.
