When traditional temperature measurement equipment performs non-contact, long-distance temperature measurement, the temperature measurement distance is relatively fixed, resulting in deviations in the measured temperature in a few cases, making the test results inaccurate.

In view of this, this application proposes a temperature measurement equipment and access control system, aiming to solve the problem that when traditional temperature measurement equipment measures the temperature of users, the temperature measurement distance is relatively fixed, resulting in possible deviations in the measured temperature in a few cases, making The problem of inaccurate test results. 1 to 4 are structural schematic diagrams of an embodiment of the access control system proposed in this application.

Please refer to Figures 1 to 2. The temperature measurement device 100 proposed in this application is used to sense the temperature of the human body in the gate passage 211. The gate passage 211 extends along the first direction X. The temperature measurement device 100 includes a support 1 , installation part 2, temperature measuring part 3 and position adjustment device 4. The mounting member 2 is installed on the support member 1 , and the mounting member 2 and the gate channel 211 are arranged oppositely along the second direction Y. The temperature measuring component 3 is installed on the mounting component 2 and faces the corresponding gate passage 211 for sensing the temperature of the human body passing through the corresponding gate passage 211 .

The position adjustment device 4 is connected to at least one of the support member 1 and the installation member 2 to adjust the relative position of the temperature measuring member 3 and the corresponding gate channel 211 in the second direction Y. The first direction X and the second direction Y are perpendicular to each other.

In this application, the first direction X and the second direction Y are two relative directions, where the first direction direction.

In the technical solution of this application, the temperature measurement device 100 senses the temperature of the human body in the gate passage 211 through the temperature measurement component 3, and the temperature measurement component 3 is installed on the mounting component 2, and the mounting component 2 is installed on the support component 1. Therefore, when the position adjustment device 4 drives the support member 1 or the installation member 2 to move, the relative position of the temperature measurement member 3 and the corresponding gate channel 211 can be adjusted, so that the temperature measurement member 3 can sense the user's temperature more accurately. body temperature. Specifically, by driving the support member 1 or the installation member 2 to drive the temperature measuring member 3 closer to or away from the gate channel 211, the temperature measuring distance of the temperature measuring member 3 is adjusted, so that the temperature measuring distance of the temperature measuring member 3 can be more adapted to the current situation. The weather factors and environmental factors enable the temperature measurement component 3 to sense the user's body temperature more accurately.

In some embodiments, the support 1 includes a fixed section 11 and a movable section 12 that are both extended along the second direction Y and connected in sequence. The movable section 12 is movably installed on the fixed section 11 along the second direction Y. The mounting part 2 is installed on the movable section 12; the position adjustment device 4 includes a driving component 41 connected with the movable section 12 for driving the movable section 12 to move along the second direction Y.

Specifically, the support member 1 includes a fixed segment 11 and a movable segment 12 connected in sequence, and the mounting member 2 is installed on the movable segment 12 . Therefore, when the position adjustment device 4 drives the movable segment 12 to move along the second direction Y through the driving assembly 41, the movable segment 12 can drive the mounting member 2 to move together, thereby adjusting the temperature measuring member 3 and the corresponding gate channel 211 in the second direction Y. distance, so as to make the temperature measurement effect of the temperature measurement piece 3 more accurate.

Please refer to FIGS. 1 to 3 . In some embodiments, a movable channel 121 extending along the second direction Y is provided on the side of the movable section 12 facing the fixed section 11 . The side wall at the mouth of the movable channel 121 faces the fixed section 11 . Section 11 is provided with an annular chute 122 . The outer periphery of the fixed section 11 is provided with external threads, and the fixed section 11 is inserted into the movable channel 121 .

The driving assembly 41 includes a first motor 411 , a driving gear 412 and a driven gear 413 . The first motor 411 is installed on the movable section 12 , and the output shaft of the first motor 411 extends toward the fixed section 11 along the second direction Y. The driving gear 412 is installed on the output shaft of the first motor 411. The driven gear 413 meshes with the driving gear 412, and a threaded hole corresponding to the external thread of the fixed section 11 is provided in the middle of the driven gear 413 to connect with the fixed section. 11 screw connection. The driven gear 413 is also provided with a plurality of slide blocks 414 corresponding to the annular chute 122. The plurality of slide blocks 414 are slidably installed in the annular chute 122, so that the driven gear 413 is driven by the driving gear 412. When moving along the second direction Y, the movable section 12 can be driven to move.

In specific applications, the first motor 411 drives the driving gear 412 to rotate through the output shaft, and the driving gear 412 drives the driven gear 413 to rotate. The driven gear 413 is threaded with the fixed section 11 through the threaded hole, so the driven gear 413 rotates It is possible to move on the fixed section 11 in the second direction Y. In practical applications, the second direction Y is generally the up-down direction. The driven gear 413 is also provided with a plurality of slide blocks 414 corresponding to the annular chute 122 at intervals, so the driven gear 413 can rotate relative to the movable section 12, and when the driven gear 413 moves upward along the second direction Y The movable section 12 can be lifted upward, thereby driving the movable section 12 to move together. When the driven gear 413 moves downward along the second direction Y, the movable section 12 will move downward together due to lack of support.

It should be noted that the driving assembly 41 can also drive the movable section 12 to move along the second direction Y through other implementations. For example, the driving assembly 41 can also drive the movable section 12 to move along the second direction Y by providing a cylinder 215a.

In some embodiments, the inner diameter of the side of the annular chute 122 away from the fixing section 11 is larger than the inner diameter of the side close to the fixing section 11 to limit the plurality of slide blocks 414 in the annular chute 122 . Each slide block 414 is arranged corresponding to the annular slide groove 122, and the inner diameter of the annular slide groove 122 on the side away from the fixed section 11 is larger than the inner diameter on the side close to the fixed section 11. Therefore, when the plurality of slide blocks 414 move along the second direction Y , the plurality of slide blocks 414 will not disengage from the annular slide groove 122 . When the driven gear 413 moves downward along the second direction Y, the plurality of slide blocks 414 will contact the side of the annular chute 122 close to the fixed section 11 , thereby driving the movable section 12 to move together, which also makes the movable section 12 It is more stable when moving downward.

In addition, some structures can be added to the annular chute 122 to reduce the sliding resistance between the slider 414 and the annular chute 122 , such as filling the annular chute 122 with balls or lubricating oil to help the slider 414 rotate relative to the annular chute 122 .

In specific applications, the movable section 12 may detach from the movable channel 121 when moving along the second direction Y, causing the movable section 12 to separate from the fixed section 11 and affecting subsequent use. In some embodiments, the movable section 12 further includes a limiting block 133 provided on the side wall of the movable channel 121 . The fixed section 11 includes a housing 112 and a support portion 111 provided in the housing 112. The housing 112 is provided with a movable groove corresponding to the limiting block 133, so that the limiting block 133 can extend into the housing 112. Stoppers 113 are respectively provided at both ends of the support portion 111 in the second direction Y. The two stoppers 113 are configured to abut against the stopper 113 when the limiter 133 approaches.

When the movable section 12 moves, the limiting block 133 moves together in the movable slot. When the movable section 12 is about to separate from the fixed section 11 , the limiting block 133 will be close to the stopping block 113 , thereby preventing the movable section 12 from continuing to move. When the movable section 12 is about to be completely connected with the fixed section 11 , the limiting block 133 will be close to the other stopping block 113 , thereby preventing the movable section 12 from continuing to move. The stop block 113 blocks the movement of the limit block 133, thereby limiting the movable section 12 to the fixed section 11, so that the movable section 12 can be used continuously and stably in the future.

In some embodiments, the temperature measuring element 3 has a temperature measuring end for sensing external temperature. The mounting member 2 is rotatably mounted on the support member 1 around an axis extending along the third direction Z. The position adjustment device 4 includes a driving assembly 41 connected to the mounting member 2 . The driving assembly 41 is used to drive the mounting member 2 to rotate around an axis extending along the third direction Z to adjust the orientation of the temperature measuring end of the temperature measuring member 3 . The first direction X, the second direction Y and the third direction Z are arranged vertically in pairs.

In this application, the third direction Z is another relative direction, and the third direction Z can be set as the extension direction of the mounting member 2 .

In actual applications, users may be in different locations to verify their identity and pass the access control based on their usage habits, which results in a certain deviation in the location where the user waits for temperature measurement. At this time, the driving assembly 41 can drive the mounting member 2 to rotate around the axis extending along the third direction Z, and the temperature measuring member 3 will rotate together, thereby adjusting the orientation of the temperature measuring end of the temperature measuring member 3 so that the temperature measuring member 3 The temperature end can also face the user waiting for temperature measurement to ensure that the temperature measurement component 3 can accurately sense the user's temperature.

Specifically, the driving assembly 41 includes a first motor 411, a worm 415 and a worm gear 416. The first motor 411 is installed on the support 1 , and the output shaft of the first motor 411 extends along the second direction Y. The worm 415 is connected to the output shaft of the first motor 411 , and the worm gear 416 is fixedly installed on the mounting piece 2 . The worm gear 416 is in mesh with the worm 415 and is configured to be driven by the worm 415 to rotate about an axis extending along the third direction Z.

When the orientation of the temperature measuring end of the temperature measuring element 3 needs to be adjusted, the driving assembly 41 can drive the worm 415 to rotate around the axis extending along the second direction Y through the first motor 411, and the rotation of the worm 415 can drive the worm gear 416 to rotate around the third direction Y. The axis extending in direction Z rotates, and the worm gear 416 is fixedly installed on the mounting part 2, so the worm gear 416 can drive the mounting part 2 to rotate together.

It should be noted that the angle of the temperature measuring part 3 does not need to be adjusted every time in actual application, and the required rotation angle is generally small. The rotation of the temperature measuring part 3 is to meet the user's more diverse needs. It can also ensure that the temperature measurement effect of the temperature measurement piece 3 is more stable. In addition, in this application, the driving assembly 41 can drive the movable section 12 to move along the second direction Y through the first motor 411, and can also drive the mounting member 2 to rotate. When the two activities need to be realized together, the driving assembly 41 can be provided with a first motor 411 and a third motor to drive the movable section 12 and the mounting member 2 respectively.

Referring to Figures 1 to 4, this application also proposes an access control system 200. The access control system 200 includes the temperature measurement device 100 in any of the above embodiments and at least two gates 210. At least two gates 210 are spaced apart along the third direction Z to define a gate channel 211 between two adjacent gates 210 , and the gate channel 211 is arranged opposite to the mounting member 2 along the second direction Y. Each gate 210 includes a gate body 212 and an information collection device 220 installed on the gate body 212.

When the user is in actual use, he or she can verify his/her identity information through the information collection device 220, thereby opening the gate channel 211. During this process, the temperature measurement device 100 will measure the user's temperature. When the user's body temperature is normal, the gate channel 211 will be released normally. When the user's body temperature is abnormal, the access control system 200 will issue a voice alarm and prompt the user to enter again. Conduct temperature measurement to prevent abnormalities in the test results themselves.

In some embodiments, the information collection device 220 is movably installed on the gate body 212 along the second direction Y. The access control system 200 also includes a second motor 230. The second motor 230 is connected to the information collection device 220 to drive the information collection device 220 to move in the second direction Y.

The access control system 200 drives the information collection device 220 to move through the second motor 230, so that the information collection device 220 can move along the second direction Y. In practical applications, the second direction Y can be set as an up-down direction, so the information collection device 220 can move upward along the second direction Y, thereby adjusting the height of the information collection device 220 to facilitate users of different heights to verify identity information. In practical applications, the information collection device 220 may be a facial recognition device, an access card reading device, or a fingerprint collection device. When used by users of different heights, adjusting the height of the information collection device 220 can make the user The user experience is better.

There are many implementations for the access control system 200 to drive the information collection device 220. This application proposes one as an example. The access control system 200 includes a base 240 and a second motor 230 . The base 240 is used for installation of each gate 210, and an installation cavity 241 is provided inside the base 240. The output shaft of the second motor 230 extends along the third direction Z, and a plurality of output bevel gears 232 are provided on the output shaft of the second motor 230. The plurality of output bevel gears 232 are arranged in one-to-one correspondence with the gate 210.

Each gate 210 also includes an installation channel 250 provided on a side of the gate body 212 away from the base 240 and a movable component installed in the installation channel 250. The installation channel 250 extends along the second direction Y. The movable component includes a rotating rod 251 and a movable sleeve 252 both extending along the second direction Y. The rotating rod 251 includes a first part extending into the installation cavity 241 and a second part located in the installation channel 250 . An input bevel gear 231 is provided at one end of the rotating rod 251 close to the first part. The input bevel gear 231 is used to mesh with the corresponding output bevel gear 232 to drive the rotating rod 251 to rotate around the axis in the second direction Y;

The end of the movable sleeve 252 away from the base 240 is connected to the information collection device 220 . The movable sleeve 252 is sleeved on the second part and screwed with the second part. The movable sleeve 252 is configured to drive the information collection device 220 to move along the second direction Y when the rotating rod 251 rotates.

In some embodiments, each gate body 212 is provided with an accommodating cavity 213 , and the accommodating cavity 213 is provided with an overhanging opening toward the corresponding gate channel 211 . Each gate 210 also includes a blocking rod 214 installed in the accommodation cavity 213 to rotate around an axis extending along the first direction It is driven to extend from the extending opening to block the corresponding gate passage 211.

When the user's identity verification fails or the body temperature is abnormal, the gate 210 should prevent the user from passing through the gate channel 211. Specifically, each gate 210 can drive the blocking rod 214 to rotate through the driving member 215, and the blocking rod 214 can extend from the outward opening during the rotation, so as to lie across the corresponding gate passage 211, blocking the passage of users. .
