Description of the Invention: [Technical Field] [0001] The present invention relates to a non-contact temperature sensing device, and more particularly to a non-contact temperature sensing device capable of measuring distance. [Previous technique _ surgery] [0002] Temperature is the physiological index of the living body, you can know whether the living body is in a healthy state. There are some contact type temperature rush to measure the temperature of the forehead or skin, but these contact types When the temperature is rushed for temperature measurement, there may be a risk of exposure to infectious agents. Therefore, there is a non-contact temperature measurement device on the market to avoid the risk of infection. [0003] The infrared temperature sensor inside the non-contact type temperature measuring device converts the sensed infrared temperature into a proportional voltage signal through photoelectric conversion, and obtains the temperature value of the temperature object to be tested through appropriate calculation, and then passes through the display. Display the reading. However, the change in the magnitude of the voltage signal is inversely proportional to the measured distance, that is, when measuring the temperature of the body to be tested at the same temperature, the measurement result will follow the infrared temperature sensor and the temperature object to be tested. The distance between the two is different, and the temperature data is different. For example, the closer the temperature object is to the infrared temperature sensor, the higher the measured temperature value is. In order to effectively avoid the influence of the measuring distance on the accuracy of the temperature sensor, a non-contact type temperature measuring device must be configured with a measuring distance positioning design. [0004] Referring to the first figure, it is an architectural diagram of a conventional visible beam focusing and distance system. The infrared thermometer 90 having a light sighting system includes a two light source 92, a dichroic unit 94, and a temperature sensor 96. Each of the light sources 90 transmits light to a temperature object P through each of the light collecting units 94, and the temperature sensor 96 is configured by a suitable design. 100116224 Form No. A0101 Page 4 of 271002027224-0 201245678 When the distance from the temperature object P is exactly equal to a predetermined distance D, the two visible rays emitted by the light sources 90 will be concentrated by the two separated spots into a single spot. In this way, the temperature error caused by the different measurement distances can be greatly reduced. [0005] However, the light source positioning indication used by the infrared thermometer described above has design disadvantages, for example, it must be measured by others to check whether the two LED lights that are illuminated are combined by the movement of the measuring head. The temperature subject P is unable to self-measure the amount of light by illuminating the two rays of light and the concentrated spot on the forehead. SUMMARY OF THE INVENTION [0006] In view of the foregoing, it is an object of the present invention to provide a non-contact temperature sensing device that can be distance measured.

The reflected signal is formed by an i-wave circuit composed of a resistor (5) and a capacitor c connected to the sensing unit 120 to form an analog signal of an analogy form and transmitted to the first analog-to-digital conversion unit 18G. The first analog-to-digital conversion unit 18() receives the filtered reflected signal of the analog form, and converts the filtered analog signal of the analog form into a reflected signal of a corresponding digital form and transmits To the central processing unit 14A. The central processing unit 140 has a predetermined measurement range. The central processing unit 140 determines whether the reflected signal falls within the preset measurement range to correspondingly determine an amount between the non-contact temperature sensing device 1 and the temperature object P. Measuring distance. The smart judgment refers to determining the measurement distance between the non-contact temperature sensing device 10 and the temperature object to be tested p according to conditions such as the color, gloss, and fineness of the skin of the body P to be tested. If the central processing unit determines that the reflected signal of the digital form falls within the preset measurement range, the central processing unit 14 determines that the non-contact temperature sensing device 10 and the temperature standby body P are in proper measurement. The distance, the central processing unit 140 sends a pair of distance indicating signals corresponding to the magnitude of the reflected signal in the form of digits, and the distance indicating signal is transmitted to the measuring distance indicating unit 2 via the input/rounding unit 190. To initiate the measurement distance prompting unit 2〇〇. The measuring distance prompting unit 2 generates a corresponding 100116224 Form No. A0101 Page/Total 27 Page 1002027224-0 201245678 Ο [0028] ❹ [0030] [10030] 100116224 The distance indicating information of the distance indicating signal is The user is informed that the distance between the non-contact temperature sensing device 10 and the temperature sensing body 落 falls within the preset measuring distance, and the temperature measurement can be performed on the temperature sensing body. The measurement distance indicating unit 200 can be a display 200, a speaker component 200, or a light-emitting component 200C, and can generate different audio, illumination colors or icons corresponding to different positioning prompt signals. The display device 200 can be a liquid crystal display (LCD), and the speaker element 200 can be a buzzer or a mouthpiece. The light-emitting element 200C can be a light-emitting diode. Equivalent elements that are equivalent to other equivalents are intended to be included within the scope of the invention. In addition, when the central processing unit 140 determines that the non-contact temperature sensing device 10 and the temperature standby body P are located at an appropriate measurement distance, the central processing unit 140 may also generate a temperature measurement enable signal and transmit the signal to the temperature measurement enable signal. The temperature sensing unit 130 activates the temperature sensing unit 130 and starts measuring the temperature of the temperature side body P. In this embodiment, the temperature sensing unit 130 is an inf rared sensor, and preferably, the temperature sensing unit 13 is a thermistor for sensing the temperature of the body to be measured. Infrared radiation is transmitted to the second analog-to-digital conversion unit 21A. The second analog-to-digital conversion unit 21 converts the temperature value into a corresponding temperature signal and transmits it to the central processing unit 14A. When the temperature of the temperature P to be measured is actually measured, the temperature sensing unit 130 senses the temperature object ρ within a predetermined range, and extracts at least one temperature value, which is a signal in the analogy form. The temperature value is transmitted to the form bat face 1 page u / page 27 1002027224-0 201245678 第一海 first analog digital conversion unit 21Q 'the second analog digital conversion unit 210 converts the temperature value of the analog form into a corresponding At least one temperature signal in the form of a digit, the temperature signal being passed to the central processing unit 14A. [0032] The method of perceiving the single TL 130 is: moving the non-contact temperature sensing device 10 back and forth within the predetermined range, while capturing at least one temperature value, and via the second analog digital position The conversion unit 210 converts to a corresponding temperature signal and transmits it to the central processing unit 14A. When the non-contact temperature sensing device 10 moves within the predetermined range (e.g., gradually approaching the temperature object to be tested p from a distance), the temperature signals are correspondingly gradually increased. When the non-contact temperature sensing device 丨0 exceeds the predetermined range (e.g., too close to the temperature object P), the temperature signal correspondingly drops. The central processing unit 140 captures the maximum value of the temperature signal, and after being compensated by the ambient temperature, transmits the maximum temperature signal to the display device 200A through the input/output early element 190 and displays the display by the display 200A. Temperature signal. In addition, the central processing unit 140 determines whether the temperature signal is greater than a preset temperature range, and if the temperature signal is greater than the preset temperature range, stopping the non-contact temperature sensing device 10 to sense the temperature to avoid the non- The contact temperature sensing device 10 is damaged by sensing an excessively high temperature. Moreover, the central processing unit 140 also determines whether the temperature signal is less than the preset temperature range, and if the temperature signal is less than the preset temperature, the display system outputs a "Lo signal". In summary, the steps of the 蚱 contact temperature sensing device 1 when actually measuring the temperature are as follows: 100116224 Form No. A0101 Page 12 / Total 27 Page 1002027224-0 [0033] 201245678 [0034] [0035 [0036] Ο [0037]

Then, the sensing unit 12 〇 receives a reflected signal of one of the signals reflected by the temperature measuring object ρ. Finally, the single-chip microprocessor determines whether the reflected signal determines whether the reflected signal falls within a predetermined measurement range, and after the step is established, the remote single-chip microprocessor generates a certain distance warning signal or a temperature. Measure the enable signal. Referring to FIG. 5, it is a flow chart of the non-contact temperature sensing method for the distance measurement according to the present invention. When the non-contact temperature sensing device 10 is used, the switching unit 16 is required to activate the non-contact temperature sensing display 10. When the non-contact temperature sensing device 10 is activated, the central processing unit 140 drives the non-contact temperature sensing device 10 to return to the initial setting (step S400). Thereafter, a pulse signal is transmitted by the transmitting unit 11 〇 corresponding to the number of times of transmission (step S402), and the pulse signal has the operating frequency. The pulse signal is transmitted to the temperature object to be measured, and the temperature object ρ reflects the pulse signal. The pulse signal is generated by the pulse width modulation control unit 150 to control the operating frequency of the transmitting unit 110. The sensing unit 120 receives the reflected pulse signal that reflects the pulse signal via the temperature object to be tested ρ (step S404), and transmits the reflected pulse signal to the counting unit 170 and the first analog digital conversion unit 18〇. . The counting unit 170 determines whether the operating frequency and the number of transmissions of the reflected pulse signal and the working frequency of the pulse signal transmitted by the transmitting unit 110 are 100116224. Form No. 1010101 Page 13 / Total 27 pages 1002027224-0 [0039] 201245678 The rate and the number of shots are the same (step S406). After the step S406, if the counting unit 170 determines that the operating frequency and the number of transmissions of the reflected pulse signal are different from the pulse signal, the central processing unit 14 further determines the non-contact temperature sensing device. Whether the timeout is perceived (S422) [0040] After the step S422, if the central processing unit 14 determines that the non-contact temperature sensing device 10 senses the timeout, an error message is outputted by the display 2A (S424) . [0041] After the step S422, if the central processing unit 14 determines that the non-contact temperature sensing device ίο does not exceed the timeout, the step S4〇2 is repeated, and the pulse signal is retransmitted by the transmitting unit 110. [0] After step S406, if the operating frequency and the number of transmissions of the counting unit 17 riding the reflected pulse signal are the same as the pulse signal, the reflected pulse signal is transmitted to the central processing unit 14A.

Perceived timeout (S422). [0045] 100116224 After the step S422, if the central processing unit 14G determines that the non-contact/dish sensing device 10 senses the timeout, then the display 2A outputs a wrong form, number A0101, page 14/total 27 s 1002027224-0 201245678 [0047] ❹ [0049] Error message (S 4 2 4 ). After the step S422, if the central processing unit 140 determines that the non-contact temperature sensing device 10 has not perceived the timeout, the process returns to step S402, and the pulse signal is retransmitted by the transmitting unit 110. After the step S410, if the central processing unit 140 determines that the reflected pulse signal falls within the preset measurement range, transmitting a pair of distance indicating signals corresponding to the magnitude of the reflected pulse signal to drive the measuring distance prompting unit 2 0 0 A certain distance prompt information is generated to prompt the user holding the non-contact temperature sensing device 10 to perform temperature measurement on the temperature test object P (step S412). The measurement distance indicating unit 200 can be a display 200A, a speaker element 20 0B or a light-emitting element 200C, and can generate different audio, illumination colors or icons corresponding to different positioning prompt signals. The central processing unit 140 transmits a temperature measurement enable signal to the temperature sensing unit 130 to activate the temperature sensing unit 130 to read the temperature of the temperature subject P (step S414). The temperature sensing unit 130 captures at least one temperature value of the analog form and transmits the analog value to the second analog digital conversion unit 210, and the second analog digital conversion unit 210 converts the temperature value into at least one of the corresponding digital forms. The temperature signal is passed to the central processing unit 140. The central processing unit 140 has a predetermined temperature range, and the central processing unit 140 determines whether the temperature signal is smaller than the preset temperature range (step S415). After the step S415, if the central processing unit 140 determines that the temperature signal is less than the preset temperature range, the display 200A displays a "Lo" signal (S416), and the central processing unit 140 further determines 100116224 Form No. A0101. 15 pages/total 27 pages 1002027224-0 201245678 Whether the non-contact temperature sensing device 10 senses the timeout (S 4 2 2). [0050] After the step S422, if the central processing unit 140 determines that the non-contact temperature sensing device 10 senses the timeout, an error message is outputted by the display 200A (S 4 24). [0051] After the step S422, if the central processing unit 140 determines that the non-contact temperature sensing device 10 is not aware of the timeout, the process returns to step S402, and the pulse signal is retransmitted by the transmitting unit 110. [0052] After the step S415, if the central processing unit 140 determines that the temperature signal is not less than the preset temperature range, it is further determined whether the temperature signal is greater than the preset temperature range (S417). [0053] After step S417, the central processing unit 140 transmits the temperature signal to the display 200A via ambient temperature compensation, and the display 200A displays the corresponding maximum temperature signal (step S420). [0054] After the step S417, if the central processing unit 140 determines that the temperature signal is indeed greater than the preset temperature range, the display 200A displays a "Hi" signal (S418), and the central processing unit 140 ends the non-contact temperature. The action of the sensing device 10 is prevented to prevent the non-contact temperature sensing device 10 from being damaged due to the sensing of high temperatures. [0055] In summary, the non-contact temperature sensing device 10 of the present invention can detect the non-contact temperature sensing device 10 in advance through the transmitting unit 110 and the sensing unit 120. a measuring distance between the temperature measuring objects P, and when the measuring distance falls within the preset measuring range, transmitting a distance indicating signal to prompt to hold the use of the non-contact temperature sensing device 10 Temperature measurement can be performed, or directly, 100116224 Form No. A0101 Page 16 / Total 27 Page 1002027224-0 201245678 Measure the temperature value of the body p to effectively avoid the temperature caused by the difference in measurement distance The measurement error value is generated, and the temperature test body p can measure the body temperature by itself.
