1. this dynamic wisdom monitoring device of palm print uses through the cooperation of last pile body, rotatory mount table, first layer mount table, second floor mount table, third layer mount table, camera and rotating electrical machines. The rotary mounting table rotates at a certain speed under the action of the rotary motor, the camera arranged on the rotary mounting table can also follow the rotation, namely 360-degree angle shooting is realized, when a palm is drawn from the periphery of the device, the linear speed of the camera is different due to the fact that the rotational angular speed of the camera arranged on the rotary mounting table is the same due to the fact that the three mounting tables with different radiuses of the first layer of mounting table, the second layer of mounting table and the third layer of mounting table exist, namely, a speed gradient is formed, and the linear speed of the camera is sequentially increased from bottom to top. The palm of the hand that is drawn around the device has a certain speed, so in order to ensure the definition of the shot, it should be ensured that the speed of the camera coincides with the speed of movement of the palm. The former design meets this requirement. When the palm is scratched from the periphery of the device, the movement speed of the palm is in the linear speed range of the camera, so that the palm prints of the palm can be shot more clearly for the camera shooting at high speed. Thereby achieving the effect of dynamically detecting palmprint in all directions of the device.
2. This dynamic wisdom monitoring device of palm print uses through the cooperation of last pile body, rotatory mount table, first layer mount table, second floor mount table, third layer mount table, camera and rotating electrical machines. The traditional palm print dynamic monitoring device needs to press the palm center part of the palm on the receiving module of the device completely, and the next operation can be performed after the receiving module acquires the palm print information completely, but if a large amount of water exists on the palm of a user, the device often cannot acquire the palm print information successfully. The device provided by the invention does not need to press the palm on the receiving module of the device completely, only needs to shoot the palm which is scratched from the camera, and the moisture on the palm does not influence the detection result and does not cause unsuccessful information acquisition of palmprint.

3. This dynamic wisdom monitoring device of palm print uses through the cooperation of last pile body, rotatory mount table, first layer mount table, second floor mount table, third layer mount table, camera and rotating electrical machines. The traditional palm print dynamic monitoring device needs to place the palm on the device completely, after the device obtains palm print information, the palm print information is processed, corresponding actions are finally made, and if the palm placement positions are not right, repeated operations are possibly needed, namely the device detection time is longer, the detection efficiency is lower, and the detection actions are more complicated. In the invention, the palm is merely drawn from the periphery of the device, and the camera can shoot the palmprint of the palm, then process the palmprint and finally perform corresponding actions. Therefore, the effects of short detection time and high detection efficiency are achieved without pressing the palm in the palm print receiving area to acquire the palm print information for a long time.
4.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1-9, the palm print dynamic intelligent monitoring device comprises a main pile body 1 and a rotary mounting table 2, wherein the main pile body 1 comprises a lower pile body 11 and an upper pile body 12, and the rotary mounting table 2 is fixedly mounted on the upper pile body 12. The rotary mounting table 2 is a device having a three-layer structure, each layer being designed with specific functions and advantages. The diameters of the first stage 21, the second stage 22 and the third stage 23 are sequentially increased, and the purpose of this design is to accommodate cameras 3 of different diameters and to ensure that they have the same angular velocity when rotated. The diameters of the circumscribed circles of the first-layer mount 21, the second-layer mount 22, and the third-layer mount 23 become gradually larger, and this design takes into consideration the moving speed of the camera 3. When the camera 3 rotates, the linear speed of the camera end will be different due to the different diameters. This design thus allows the camera 3 to have a range of speeds during movement. When the palm print is drawn from the periphery of the device, the palm print has a certain running speed. In order to ensure the clarity of shooting, the movement speed of the camera 3 needs to be consistent with the movement speed of the palmprint, i.e. the camera 3 and the palmprint are relatively stationary. At this time, the palm print is most clearly photographed. The design of the multi-layer camera 3 further expands the speed float zone of the camera 3. This means that the hand prints can be matched with a relatively close speed for different speeds, so that shooting can be performed more clearly. The design can adapt to various environments and use conditions, so that the shooting effect is more ideal. In addition, the design of the rotary mount 2 can also improve the efficiency and effect of photographing. Since the movement speed of the camera 3 is matched with the movement speed of the palmprint, continuous shooting of the palmprint can be realized without blurring or omission. The continuous shooting can improve the accuracy and reliability of palm print recognition, so that the method can be widely applied to the fields of safety monitoring, identity recognition and the like. This design can ensure that the camera 3 has the same angular velocity when rotating, and at the same time has different linear velocities to meet the palm print shooting requirements of various velocities. In addition, the design of the multi-layer camera 3 can expand the speed floating interval of the camera 3 and adapt to various different palm print speeds, so that a clearer shooting effect is realized.
The whole of the camera is in a round table shape with a large upper part and a small lower part, and the design ensures that the mounting table can stably run when rotating and can adapt to cameras 3 with various diameters. The first-layer mounting table 21 is fixedly mounted at the bottom of the upper pile body 12, and provides a stable foundation for the entire rotary mounting table 2. The second-layer installation table 22 and the third-layer installation table 23 are sequentially installed at the middle and upper portions of the upper pile body 12, and this design can make the photographing angle wider and can adapt to objects or palmprints of different heights. The cameras 3 are uniformly mounted on the side surfaces of the first-layer mounting table 21, the second-layer mounting table 22, and the third-layer mounting table 23. This design can ensure the definition and accuracy of shooting. Cameras 3 are mounted on the sides of the hexagonal prism, and the cameras 3 of three layers correspond to each other, which means that there are three cameras 3 photographed at the same time on the same photographing plane. This design can increase the coverage of photographing and can improve the efficiency and effect of photographing. When the palm is drawn from the periphery of the device, there must be one camera 3 closest to the running speed of the palm among the three cameras 3. This camera 3 is regarded as a primary camera 3, while the remaining two cameras 3 are secondary cameras 3. The picture shot by the auxiliary camera 3 can be used as a copy or contrast copy of the picture shot by the main camera 3, and the picture shot by the main camera 3 is corrected. This design can improve the accuracy and reliability of photographing. With the aid of the sub camera 3, blurring or omission of shooting due to a change in palm speed can be avoided. Furthermore, such a design of the rotary mount 2 can also realize continuous shooting. Since the movement speed of the camera 3 is matched with the movement speed of the palmprint, continuous shooting of the palmprint can be realized without blurring or omission. The continuous shooting can improve the accuracy and reliability of palm print recognition, so that the method can be widely applied to the fields of safety monitoring, identity recognition and the like. The camera 3 is a high-speed camera 3.
The bottom of the upper pile body 12 is fixedly connected with a motor shaft of the rotary motor 4, and a machine body of the rotary motor 4 is fixedly arranged on the upper part of the lower pile body 11. The bottom of the upper pile body 12 is fixedly connected with a motor shaft, so that the motor can drive the upper pile body 12 to rotate all the time, and the rotation of the upper pile body 12 can further drive a mounting table mounted on the upper pile body to rotate at a certain speed.
The bottom of the upper pile body 12 is provided with an annular mounting groove 121, so that a stable and safe mounting environment is provided for protecting the camera 3. The boot 5 is fixedly mounted in the annular mounting groove 121, and this design ensures that the boot 5 does not move with rotation, thereby keeping the position of the camera 3 stable. The protection cover 5 is made of transparent materials, so that the picture shot by the camera 3 can be guaranteed not to be affected, and meanwhile, the transparent materials enable the protection cover 5 to not obstruct shooting. The cylindrical permanent magnet 51 is fixedly mounted on the top of the protective cover 5, and the design makes the installation of the protective cover 5 more firm and stable. The bottom of the protection cover 5 is fixedly arranged in the annular mounting groove 121 at the bottom of the upper pile body 12, and the design can ensure that the protection cover 5 does not rotate, namely the protection cover 5 is fixed, and the camera 3 rotates. This design can avoid interference or shielding of the picture taken by the camera 3 due to the rotation of the protective cover 5. The transparent protective cover 5 may be made of transparent glass or transparent plastics with better light transmission, such as Polycarbonate (PC), polymethyl methacrylate (PMMA), etc. The materials have the advantages of high light transmittance, high refractive index and the like, and can ensure the shooting quality of the camera 3. Meanwhile, the materials have better heat resistance and impact resistance, and can protect the camera 3 from being damaged by the external environment. Finally, the protective cover 5 can also protect the camera 3 from various external factors. For example, it can prevent dust, dirt, etc. from entering the inside of the camera 3, thereby maintaining the cleanliness and good performance of the camera 3. In addition, it can also prevent damage to the camera 3 by physical impact or collision from the outside.
The cylindrical permanent magnet 51 is fixedly installed at the top of the protection cover 5, and the permanent magnet 51 is penetrated through the top hollow portion of the upper pile body 12, so that the permanent magnet 51 does not move along with rotation, thereby maintaining the position stability of the camera 3. The presence of the permanent magnet 51 allows the coil 231 to be fixedly mounted in the third-tier mounting stage 23 without being affected by rotation. The second-layer mounting table 22 and the third-layer mounting table 23 are hollow structures, and this design can make the mounting table lighter and stronger, and can also conveniently mount and fix the camera 3. The coil 231 is fixedly installed in the third-stage installation table 23, and when the third-stage installation table 23 starts to rotate, the coil 231 fixedly installed in the third-stage installation table 23 cuts the magnetic induction lines to generate electric power. This design can be converted into electric energy by utilizing kinetic energy generated by rotation, and provides stable power supply for the camera 3. The second-layer mounting table 22 is fixedly provided with an energy storage module 221, which can store the electric quantity generated by the coil 231 and provide more stable and durable power supply for the camera 3. The energy storage module 221 may be a device for storing electric energy, such as a battery or a super capacitor, which is capable of storing the amount of electricity generated by the coil 231 and providing a stable power supply to the camera 3 when necessary.
The lower pile body 11 is provided with the mounting holes 111, the mounting holes 111 are positioned on the side edges of the lower pile body 11 and are symmetrical to each other, and the positions of the mounting holes 111 can be more stable and firm due to the design. The direct lamp 6 is fixedly installed in the installation hole 111, and the design can enable the position of the direct lamp 6 to be more accurate and stable. The direct-fired lamp 6 is designed to provide additional light when it is desired to capture a palm print drawn around the device. When the external light is darker and the shooting is not clear, the direct-fired lamp 6 is started at the moment, so that brightness is provided for shooting palmprint, and shooting definition and quality are improved. The straight spot lamp 6 is obliquely installed in the installation hole 111, and this design can make the light better illuminate the shooting area and does not waste light. The background plates 7 are fixedly arranged on two sides of the main pile body 1, and the design can provide a stable background for shooting palmprint. The face of the background plate 7 is perpendicular to the installation direction of the direct lamp 6, and the light can rebound onto the background plate 7 better through the design, so that shooting brightness is higher, and shooting is clearer. Meanwhile, the background plate 7 can provide a bottom plate color for the palmprint, so that convenience is provided for palmprint extraction on a shot photo which is better represented by the shot palmprint.
Example two
Referring to fig. 10 to 11, the upper pile body 12 is rotatably installed between the two fixing bases 9, and the first, second and third installation tables 21, 22 and 23 are fixedly installed on the upper pile body 12 in this order from left to right. A palm print collecting device 8 is slidably mounted between the two fixing bases 9, the palm print collecting device 8 comprises a palm print collecting film 82, the palm print collecting film 82 is assembled between the two sliding rods 81, the sliding rods 81 are slidably assembled on the fixing bases 9, one end of the palm print collecting film 82 is connected with a collecting film roll 84, and the other end of the palm print collecting film 82 is connected with a winding motor 83. An infrared emitter 10 is arranged at the front end of the one-side fixing seat 9. In this embodiment, the horizontal photographing is changed into the vertical photographing, and a palm print collecting device 8 is additionally arranged at the position where the palm print is marked, and the device is slidably arranged between the fixing seats 9. For a person needing palm print detection, the palm needs to be contacted with the palm print collecting film 82, at this time, the palm just blocks the light emitted by the infrared emitter 10, the sensing device positioned on the fixing seat 9 at the other side cannot receive the light, the motor starts to operate, the camera 3 starts to rotate, the palm starts to move forward, the palm slides to the end point according to the moving track of the sliding rod 81, the palm print can be shot in the sliding process, in this process, the running speed of the palm print collecting device 8 can be matched with the linear speed of the camera 3 to a certain extent, so that the running speeds of the palm print and the camera 3 are closer, clear pictures can be shot more easily, and the guarantee is provided for the follow-up image analysis of the palm print and the optimal working state of the optical element during shooting. And secondly, the method can greatly reduce the shooting quantity of photos, reduce ineffective shooting and palm print movement distance and reduce the burden for subsequent palm print analysis through an infrared starting mode. Finally, the remaining palmprint on the palmprint collecting film 82 is collected by the winding motor 83, and experimental data is provided for subsequent palmprint comparison. The palm print monitoring mode can enable a user to scratch the palm print on a fixed track, so that the user cannot slide around the palm print randomly, the camera 3 cannot shoot palm print information in a shooting range, and uncertainty of palm print acquisition is reduced.
The working principle is that when dynamic monitoring of palmprint is needed, the rotary motor 4 starts to rotate to drive the rotary mounting table 2 to start rotating, so that the camera 3 mounted on the rotary mounting table starts rotating. The person who needs palm print detection moves the palm within the detection range of the device, at the moment, the camera 3 which is closest to the palm movement speed can shoot the palm print of the hand, the shot palm print is subjected to data processing, and after the processing is finished, the next operation is performed. If the external environment is darker, when the brightness is insufficient, the direct lamp 6 is started to irradiate in a shooting area, when a palm passes through the shooting area, the light of the direct lamp 6 can enable the shooting definition of the camera 3 to be increased, and the shooting quality is improved. In addition, by the rotation of the coil 231 and the permanent magnet 51 being stationary, the generated electric energy can be stored in the energy storage module 221, providing stable support for the power supply of the camera 3.
