1 is a diagram schematically showing an integrated non-contact body temperature measurement and automatic hand sanitizer injection device according to an embodiment of the present invention, and FIG. 2 is an integrated non-contact body temperature measurement and hand sanitizer automatic injection device according to an embodiment of the present invention. Figure 3 is a block diagram showing the configuration, Figure 3 is a circuit diagram showing the configuration of an integrated non-contact type body temperature measurement and automatic hand sanitizer spray device according to an embodiment of the present invention, Figure 4 is the proximity detection module and camera module of Figure 3 5 is a diagram for explaining a user's face range recognition process and a body temperature measurement process through the camera module of FIG. 3 .

As shown in FIGS. 1 to 3, the integrated non-contact body temperature measurement and hand sanitizer automatic injection device according to an embodiment of the present invention includes an infrared proximity sensor, a digital camera, a multi-array non-contact temperature sensor, It is a device with a built-in temperature display device and guidance device, which measures body temperature while disinfecting hands, and outputs the measured body temperature value in numbers and voice.

In other words, the present invention is a device that installs a camera and a proximity sensor on a liquid disinfectant sprayer to detect a user's approach through image change detection and temperature change detection, and operates a liquid sprayer to spray a certain amount, which is a stationary or mobile structure. This is a device that can be easily installed anywhere.

To this end, the integrated non-contact body temperature measurement and hand sanitizer automatic injection device according to an embodiment of the present invention is a disinfectant spray device 10 including a body portion for storing and supplying a disinfectant and a spray nozzle 11 for spraying the disinfectant It includes an access detection module 110, a camera module 120, a non-contact body temperature measurement module 130, a display module 150, a communication module 160 and a control module 140 provided integrally.

The proximity detection module 110 is a device installed in the body of the disinfectant spray device 10 to detect the approach of a user's hand located in the front, and an infrared proximity detection sensor may be applied.

The camera module 120 is installed on the body of the disinfectant spray device 10 to photograph the body of the user located in the front and measure the distance to the user, and to photograph the face of the user in front and the distance to the user. A digital camera capable of measuring can be applied.

As shown in FIG. 5, the camera module 120 detects a specific position of the user's face according to a preset detection algorithm (ie, recognizing the face range of the human body and then detecting the temperature measurement range in the corresponding face range). and provides the detection information to the control module 140. For example, a more accurate body temperature can be measured by measuring the temperature of the rest of the face except for a region where a relatively large amount of heat is generated and a region where a low level of heat is generated.

For example, the camera module 120 uses a wide-angle camera of 70 degrees or more to capture a picture when the user approaches 0.8M, and captures a picture after measuring body temperature when the user approaches 0.4M, and captures device number, time, temperature information, etc. can be stored on a separate SD card.

As such, the present invention can control the operation of the liquid sprayer for hand disinfection by the interlocking detection function of the infrared proximity sensor and the two sensing devices of the video camera.

The non-contact body temperature measurement module 130 is a non-contact body temperature measurement sensor, and is composed of a plurality of multi-array temperature sensors, and when a disinfectant is sprayed, the body temperature of a certain area of the user's body captured by the camera module 120 is measured in a non-contact manner. It is a device that measures

The non-contact body temperature measurement module 130 may measure the body temperature value for a specific position of the user's face detected by the camera module 120 .

In this way, the present invention can precisely measure the body temperature of the face of a user approaching at the same time as spraying the disinfectant using the non-contact body temperature measurement sensor.

In other words, the present invention detects the position of the face by the camera module 120 in order to accurately measure the user's body temperature, and measures the temperature value of only the detected facial part using a non-contact temperature sensor.

Each temperature sensor constituting the non-contact body temperature measurement module 130 senses body temperature using laser or infrared rays to detect body temperature without contacting the user's body. Sensing the temperature using a laser or infrared light as described above is a well-known technology, and thus a detailed description thereof will be omitted.

Here, since the temperature sensor senses the body temperature in a non-contact manner, it is difficult to accurately measure the body temperature when wearing clothes, so it is necessary to find an exposed part of the body and measure the temperature in order to accurately measure the temperature. Therefore, in one embodiment of the present invention, it is to photograph the user in front using a camera, find the user's face through image processing, and operate the device attached to the temperature sensor in the driving module to accurately measure the temperature of the face. desirable.

However, instead of adjusting the angle of the temperature sensor to detect the body temperature as described above, it is also possible to measure the body temperature by photographing the user using an infrared camera.

As described above, when the temperature sensor detects the user's body temperature, the control module 140 determines the spray amount of the injection nozzle 11 according to the corresponding body temperature value. The amount of atomization is controlled by manipulating the power of the ultrasonic transducer (not shown) to adjust the ratio of the on/off time of the ultrasonic transducer or by adjusting the number of ultrasonic transducers (not shown) to obtain a desired amount of atomization.

In the case of a normal person, if the body temperature is 36 degrees or less than 37 to 8 degrees, it can be seen as normal, so spray normally.

As the injection nozzle 11 shown in FIG. 2 , a pump-type injection nozzle capable of adjusting the amount of spray in three steps may be used.

On the other hand, in the present invention, when measuring body temperature using a multi-array temperature sensor, the control module 140 extracts only the sensor value of the facial part recognized through the digital camera as a measurement value, and repeats it an arbitrary number of times for an arbitrary time. The average value of the measured results can be calculated as the measured value.

The display module 150 is a device that displays or outputs the body temperature value measured by the non-contact body temperature measurement module 130 as a sound. That is, the display module 150 displays the measured temperature value in numbers and letters through an LED indicator, broadcasts it through a stored guide voice, and notifies a manager through a communication module when an abnormal body temperature value is measured. . For example, the display module 150 guides the measurement result value with numbers and voice, and wirelessly notifies the administrator of the abnormal state together with the display of “normal body temperature” in the case of normal body temperature and “ideal body temperature” in the case of abnormal body temperature. have.

The communication module 160 is a device that notifies an external server when the body temperature value measured by the non-contact body temperature measurement module 130 exceeds a reference value.

As described above, according to the present invention, the normal body temperature and the ideal body temperature can be classified and displayed according to a preset standard for the measured temperature value, and the manager can be notified through the communication module 160 when the abnormal body temperature value is measured.

The control module 140 is a device for controlling the operation of the components constituting the integrated non-contact body temperature measurement and automatic hand sanitizer injection device, and when the approach of the user's hand is detected by the proximity detection module 110, the camera module ( 120), the disinfectant is sprayed to the user's hand located within the reference distance using the distance to the user measured by step 120).

The control module 140 may spray the disinfectant by operating the spray nozzle 11 when the approach of the user's hand is detected by the proximity detection module 110 and the camera module 120.

Accordingly, as shown in FIG. 4, the present invention installs a camera and an infrared proximity sensor inside the liquid sprayer through the control module 140 so that the user can access the same time through the distance measurement process through the proximity sensor and the camera. When it is detected, the injector can be operated to prevent malfunction due to the approach of objects other than people.

The control module 140 controls to measure the body temperature value for a specific position of the user's face measured by the non-contact body temperature measurement module 130 at predetermined intervals, and as a result of the measurement, the remaining body temperature values excluding the highest body temperature value The average value may be calculated as the body temperature value of the corresponding user.

That is, the control module 140 extracts the highest value among the measured temperature values, measures a set number of times for a certain period of time (eg, repeats 20 measurements for 3 seconds), and extracts the measured average value as a measured value. A value that minimizes the measurement error can be calculated.

Although not shown, the integrated non-contact body temperature measurement and automatic hand sanitizer injection device according to an embodiment of the present invention has a built-in charging battery, so that the hand sanitizer and body temperature measurement function can be performed while moving the installation location wirelessly without constant power. .

In addition, the control module 140 includes a DB for storing normal body temperature reference value information, user information, and time information at which body temperature was measured. For example, when the subject photographed by the camera module 120 is less than 1 year old, it becomes 37.5 degrees or less, when it is 2 years old or less, it becomes 37.2 degrees or less, and when it is 5 years old or less, it becomes 37 degrees or less.

In addition, when the subject photographed by the camera module 120 is 7 years old or older, the angle is 36.7 degrees to 37 degrees or less.

Although not shown, the present invention further includes a voice guidance module for providing voice guidance so that the user gazes at the camera module 120 in a floating posture while being separated from the camera module 120 by a predetermined distance.

In addition, the control module 140 may subdivide the health state of the subject according to the magnitude of the temperature difference obtained by subtracting the normal body temperature reference value from the subject's facial body temperature.

For example, if the subject's facial temperature is 0.2 degrees higher than the normal body temperature reference value, it is classified as a state of interest, if it is 0.4 degrees higher, it is classified as a cautionary state, and if it is 0.6 degrees higher, it is classified as a dangerous state.

Meanwhile, an antifouling coating layer made of an antifouling coating composition may be applied to the outer surface of the injection nozzle 11 to effectively prevent adhesion and removal of contaminants. Here, the antifouling coating composition contains cocoamphodiacetate and alkyl glycol ether in a molar ratio of 1:0.01 to 1:2, and the total content of cocoamphodiacetate and alkyl glycol ether is 1 to 10 based on the total aqueous solution % by weight. In addition, the molar ratio of the cocoamphodiacetate and the alkyl glycol ether is preferably 1:0.01 to 1:2. When the molar ratio is out of the above range, the coating property is deteriorated or the moisture adsorption on the surface increases after application, so that the coating film is removed. There is a problem being The cocoamphodiacetate and alkyl glycol ether are preferably used in an amount of 1 to 10% by weight in the aqueous solution of the entire composition. If the content is less than 1% by weight, the coating property is reduced, and if the content exceeds 10% by weight, the thickness of the coating film increases. Crystallization is likely to occur.

On the other hand, as a method of applying the antifouling coating composition to the outer surface of the spray nozzle 11, it is preferable to apply it by a spray method. In addition, the final coating film thickness of the outer surface of the injection nozzle 11 is preferably 550 ~ 2000 Å, more preferably 1100 ~ 1900 Å. If the thickness of the coating film is less than 550 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and if it exceeds 2000 Å, there is a disadvantage in that crystallization of the coated surface is easy to occur. In addition, this antifouling coating composition can be prepared by adding 0.1 mole of cocoamphodiacetate and 0.05 mole of alkyl glycol ether to 1000 ml of distilled water and then stirring.

In the above, preferred embodiments according to the present invention have been shown and described. However, the present invention is not limited to the above-described embodiments, and various modifications can be made by anyone having ordinary knowledge in the technical field to which the present invention belongs without departing from the gist of the present invention appended within the scope of the claims. .
