Detailed Description
The invention is further described in connection with the following drawings and detailed description in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the invention more clear and easy to understand:
As shown in fig. 1-3, an infrared thermometer comprises a mounting frame 1, an infrared thermal imager 2, a first circuit board 3, a second circuit board 4, a temperature sensor 5 and a temperature processing module, wherein the first circuit board 3 is horizontally fixed at the top of the mounting frame, the second circuit board 4 is vertically fixed in the mounting frame, the infrared thermal imager 2 is arranged on the lower surface of the first circuit board 3, the temperature sensor 5 is arranged on one side of the infrared thermal imager 2 of the second circuit board 4, the temperature processing module is arranged in the mounting frame 1, and the temperature processing module is connected with the infrared thermal imager 2 and the temperature sensor 5.
In the scheme, the temperature sensor 5 is used for replacing the blackbody, so that the problem that the whole infrared thermometer needs to be made into two separate parts by using the blackbody is avoided, and the problems of greatly improving the cost and greatly limiting the use of the blackbody are also avoided. Simultaneously thermal infrared imager 2, first circuit board 3, second circuit board 4, temperature sensor 5, temperature processing module etc. all are set up in the mounting bracket for the volume of whole device can further reduce, has reduced the restriction of using, is convenient for remove whole instrument. The thermal infrared imager 2 is used for measuring the measured temperature of the human body and the measured temperature of the temperature sensor 5, and transmitting the two obtained temperatures into the temperature processing module. The temperature sensor 5 may take its own part in acquiring the actual temperature of the temperature sensor 5 and pass said acquired temperature into the temperature processing module. The temperature processing module processes the three temperatures transmitted into the temperature processing module by means of the formula of 'the body surface temperature of the human body=the actual temperature of the temperature sensor+the temperature difference between the measured temperature of the human body and the measured temperature of the sensor' (the temperature difference between the measured temperature of the human body and the measured temperature of the sensor) = (the reading of the human body in the infrared sensor—the reading of the temperature sensor in the infrared sensor)), and finally obtains the actual temperature of the human body. The efficiency is greatly improved.
As a further implementation detail of the present invention, referring to fig. 1, the upper surface of the first circuit board 3 is provided with a display screen 6 and three indicator lamps 7, and the temperature processing module is respectively connected with the display screen 6 and the three indicator lamps 7.
In the above scheme, since the first circuit board 3 is horizontally arranged on the mounting frame 1, a mounting space is provided for the display 6 and the three indicator lamps 7. Meanwhile, the temperature processing module is respectively connected with the display screen 6 and the three indicator lamps 7, so that the temperature finally obtained in the temperature processing module can be displayed on the display screen 6, and meanwhile, the temperature processing module can also control the extinguishing or opening of the indicator lamps 7 according to the temperature finally obtained.
As a further implementation detail of the present invention, referring to fig. 1, the three indicator lamps 7 are respectively in three colors. In the above scheme, the three indicator lamps 7 respectively show three colors of red, yellow and green, wherein the green corresponds to a temperature interval of human body temperature lower than 37.3 degrees, the yellow corresponds to a temperature interval of 37.3 degrees to 38 degrees, and the red corresponds to a temperature interval higher than 38 degrees. When the temperature obtained by the temperature processing module is lower than 37.3 ℃, only the green light is on; when the temperature obtained by the temperature processing module is between 37.3 and 38 ℃, only the yellow lamp is lighted; when the temperature obtained by the temperature processing module exceeds 38 degrees, only the red light is lighted. By adopting the three indicator lamps 7 with different colors, a worker can judge whether the question of the person to be measured is abnormal according to the lighting condition of the lamps. The situation that the worker may missee the display temperature when using the display 6 is avoided. Meanwhile, the red and yellow indicator lamps 7 are adopted as indication colors of abnormal temperatures, so that workers can be more prominently reminded of the abnormal temperatures.
As a further implementation detail of the present invention, referring to fig. 1-3, a laser emitter 8 and a laser receiver 9 are disposed on the lower surface of the first circuit board 3, the laser emitter 8 and the laser receiver 9 are disposed on two sides of the thermal infrared imager 2, the laser emitter 8 and the laser receiver 9 are respectively connected with a temperature processing module, an optical path converter 10 matching the laser emitter 8 and the laser receiver 9 is disposed outside the mounting frame 1, the optical path converter 10 includes a "U" shaped through pipe, a reflecting mirror for reflecting laser is disposed at each corner of the through pipe, and the reflecting mirror and the through pipe corner form a right triangle.
In the above scheme, the laser emitter 8 and the laser receiver 9 are arranged on two sides of the thermal infrared imager 2 in parallel, so that the laser emitted by the laser emitter 8 returns to the laser receiver 9 again after passing through the optical path converter 10, and when the laser receiver 9 receives the laser, the thermal infrared imager 2 and the temperature sensor 5 are in a standby state. The thermal infrared imager 2 and the temperature sensor 5 are in a standby state, so that the circuit aging easily caused by the startup without stopping the startup is avoided, and the energy waste caused by the startup state is also avoided. When the person to be measured passes in front of the infrared thermometer, in the process, the person to be measured can obstruct the laser light path twice, so that the thermal infrared imager 2 and the temperature sensor 5 can measure the temperature twice, and the temperature processing module finally averages the temperature obtained by the two calculations, thereby improving the accuracy and reducing the error. The laser light path converter 10 is arranged outside the mounting frame 1, and when in use, the laser transmitter 8 and the laser receiver 9 are only required to be respectively aligned with the light path converter 10, so that the use limit is reduced. The laser transmitter 8 is matched with the light path converter 10 of the laser receiver 9 outside the mounting frame 1, so that after laser is emitted from the laser transmitter 8, the laser can return to the laser receiver 9 after being reflected by the light path converter 10, and then the laser transmitter 8 and the laser receiver 9 can be arranged in parallel, the structure of the whole infrared thermometer is simplified, the volume of the infrared thermometer is reduced, and the infrared thermometer is convenient to move and carry. The optical path converter 10 uses a U-shaped tube, and the corners of the tube are respectively provided with a reflecting mirror for reflecting laser, so that the U-shaped tube has good protection effect on the reflecting mirrors in use and avoids the interference of other light sources on the laser receiver 9. The reflector and the corner of the tube form a right triangle, so that the laser entering the U-shaped tube and the laser exiting the U-shaped tube are parallel to each other. It is ensured that the laser energy emitted from the laser emitter 8 is accurately received by the laser receiver 9.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered by the scope of the claims of the present invention.
