Description

Technical Field

[0001] This invention relates to scoliosis screening, specifically to a millimeter-wave scoliosis screening device that adapts to human height and its working method. Background Technology

[0002] With the increasing emphasis placed on the spinal health of adolescents by the country, provinces and cities across the country have begun to carry out large-scale "sports and medicine collaboration" scoliosis screening activities for adolescents. On the one hand, this can prevent and intervene in adolescent scoliosis in advance, and on the other hand, it can raise social awareness and understanding of the spinal health of adolescents.

[0003] Currently, scoliosis screening methods are mainly divided into two categories: medical imaging and manual screening. Medical imaging primarily uses CT scanners and X-ray machines for body scanning and imaging. This method involves significant radiation exposure, making it unsuitable for multiple screenings within a short period and preventing large-scale screening of students on campus. Manual screening mainly involves using a scoliosis measuring ruler and visual inspection. While manual screening avoids radiation and allows for large-scale screening on campus, the entire process is manual, requiring substantial manpower, resources, and funding, and its efficiency is relatively low. Furthermore, the determination of scoliosis is largely based on the doctor's subjective judgment, resulting in low accuracy.

[0004] Therefore, given that existing technologies can no longer meet the current and future needs for scoliosis screening, there is an urgent need for a new scoliosis screening device to replace traditional scoliosis screening methods. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a millimeter-wave scoliosis screening device and its working method that are adapted to human body height, which can effectively overcome the defects of the existing technology, such as radiation hazards, difficulty in large-scale screening, and low screening efficiency and accuracy.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A height-adaptive millimeter-wave scoliosis screening device includes a device base, a platform, and a movable chassis. A liftable screw mechanism is fixedly installed on the device base. A millimeter-wave component is fixedly installed on the front side of the liftable screw mechanism. An optical camera mounting bracket is fixedly installed on the top of the liftable screw mechanism. An optical camera is fixedly installed on the optical camera mounting bracket.

[0010] The platform is used to detect whether the standing posture of the person being tested meets the requirements and sends a detection signal to the movable chassis. After the movable chassis determines that the standing posture of the person being tested meets the requirements, it collects the height and back data of the person being tested through an optical camera, and drives the millimeter-wave component to adjust to the corresponding back position through a drive lifting screw mechanism. The millimeter-wave component emits a millimeter-wave signal to the back position under the drive of the movable chassis and receives the echo signal and sends it back to the movable chassis. The movable chassis generates a millimeter-wave image based on the echo signal and performs scoliosis analysis.

[0011] Preferably, the liftable lead screw mechanism includes a housing assembly, a lead screw transmission assembly, and a motor;

[0012] The housing assembly includes a back support, a front housing, a rear housing, a synchronous pulley protective housing, a square single bearing seat mounting plate, and a motor protective housing;

[0013] The lead screw drive assembly includes a lead screw, a T-shaped single bearing seat, a slide rail, a millimeter-wave component mounting base, a T-shaped double bearing seat, a lock nut, a coupling, a pulley shaft, a square single bearing seat, a synchronous belt, a synchronous pulley, a photoelectric switch, a photoelectric switch baffle, and a silicone anti-collision plate.

[0014] Preferably, the threaded end of the lead screw is used as the fixed end, and the fixed end of the lead screw is assembled in a T-shaped double bearing seat with double rolling bearings to complete the radial fixation of the fixed end. One side of the fixed end of the lead screw is axially locked by a lock nut engaging with the thread of the lead screw, and the other side is axially limited by an integrally formed shoulder on the lead screw to complete the axial fixation of the fixed end.

[0015] The other end of the lead screw serves as a support end, which is assembled in a T-shaped single bearing housing with a single rolling bearing. Only the support end is radially fixed. Both the T-shaped double bearing housing and the T-shaped single bearing housing are fixedly installed in the cavity of the rear housing.

[0016] The cavity inside the rear housing has slide rails fixedly installed on both the left and right sides. The millimeter wave component mounting base is threadedly connected to the lead screw and slidably connected to the slide rail. The millimeter wave component is fixedly installed on the millimeter wave component mounting base, so that the rotation of the lead screw drives the millimeter wave component to move up and down linearly along the slide rail.

[0017] Preferably, the bottom of the fixed end of the lead screw is symmetrically provided with couplings, and the bottom of the fixed end of the lead screw is equipped with couplings, pulley shafts and synchronous pulleys. The drive shaft of the motor is also equipped with couplings, pulley shafts and synchronous pulleys, and the two synchronous pulleys are connected by a synchronous belt.

[0018] A motor protective shell is fixedly installed on the equipment base. The pulley shaft and the synchronous pulley are both installed and connected to a square single bearing seat with a single rolling bearing. The square single bearing seat is fixedly installed on a square single bearing seat mounting plate. A synchronous pulley protective shell is provided on the outside of the synchronous pulley.

[0019] Preferably, photoelectric switches are fixedly installed at both the upper and lower ends on the same side of the lead screw, and photoelectric switch baffles that cooperate with the photoelectric switches are fixedly installed on the millimeter-wave component mounting base. These baffles are used to control the start and end points of the travel of the liftable lead screw mechanism. When the liftable lead screw mechanism moves to the start or end point, the photoelectric switch baffles will trigger the corresponding photoelectric switches to prevent the millimeter-wave component mounting base from moving further and avoid equipment collision.

[0020] Silicone anti-collision plates are fixedly installed on the top, bottom, and left and right sides of the housing assembly. When the photoelectric switch fails, the travel of the lifting screw mechanism will exceed the specified travel. The silicone anti-collision plates, as a physical collision protection device, will force the lifting screw mechanism to stop moving, thus avoiding damage to the equipment.

[0021] Preferably, the platform includes a platform shell and a pressure sensor array for detecting whether the standing posture of the person being tested meets the requirements, and the pressure sensor array sends a detection signal to the movable chassis.

[0022] Preferably, the movable chassis includes a movable chassis shell, a display, a frequency controller, a switch, a servo driver, a serial server, a signal processor, and an industrial computer, used to control the adaptive human height movement of the lifting screw mechanism, the operation of the millimeter-wave components, and the processing and analysis of signals.

[0023] Preferably, the signal processor receives height and back data of the person being tested collected by the optical camera, and sends control commands to the servo driver to drive the motor, using a liftable lead screw mechanism to adjust the millimeter-wave component to the corresponding back position;

[0024] The signal processor sends an operation command to the frequency controller, which in turn sends a millimeter-wave signal to the millimeter-wave component. Upon receiving the millimeter-wave signal, the millimeter-wave component begins operation. The intermediate frequency signal output by the millimeter-wave component is sampled by an ADC and converted into an IQ signal, which is then transmitted back to the signal processor. The industrial control computer receives the IQ signal sent by the signal processor, performs image reconstruction to generate a millimeter-wave image, and displays it on the monitor. Simultaneously, it performs scoliosis analysis on the millimeter-wave image and generates an analysis report.

[0025] The working method of the height-adaptive millimeter-wave scoliosis screening device includes the following steps:

[0026] S1. Once the person being tested is standing on the platform and their posture meets the requirements, the optical camera collects the height and back data of the person being tested and sends them to the signal processor inside the movable chassis.

[0027] S2. The signal processor sends control commands to the servo driver to drive the motor, and uses the liftable screw mechanism to adjust the millimeter-wave component to the corresponding back position.

[0028] S3. When the standing posture of the person being tested meets the requirements and the millimeter-wave component is adjusted to the corresponding back position, the signal processor sends an operation command to the frequency controller, the frequency controller sends a millimeter-wave signal to the millimeter-wave component, and the millimeter-wave component starts working after receiving the millimeter-wave signal.

[0029] S4. When the millimeter-wave component is working, the intermediate frequency signal output is sampled by the ADC, converted into an IQ signal, and then sent back to the signal processor.

[0030] S5. The industrial control computer receives the IQ signal sent by the signal processor, performs image reconstruction to generate a millimeter-wave image, and displays it on the monitor. At the same time, it performs scoliosis analysis on the millimeter-wave image and generates an analysis report.

[0031] Preferably, the movable chassis includes a movable chassis shell, a display, a frequency controller, a switch, a servo driver, a serial server, a signal processor, and an industrial computer, used to control the adaptive human height movement of the lifting screw mechanism, the operation of the millimeter-wave components, and the processing and analysis of signals.

[0032] (III) Beneficial Effects

[0033] Compared with existing technologies, the millimeter-wave scoliosis screening device and its working method that are adaptive to human height provided by this invention can accurately locate the position of the human back, effectively adapt to the height of different groups of people, and integrate a millimeter-wave imaging device to generate millimeter-wave images of the human back. Compared with traditional technologies, millimeter-wave technology has the advantages of being radiation-free, fast in detection, and highly accurate. At the same time, this device not only has the advantages of being radiation-free, fast in detection, and highly accurate, but also has a small size and adopts a modular installation method, so it can be used for large-scale screening, which greatly reduces the expenditure of manpower, material resources and financial resources.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0044] The following describes the specific composition and structure of the height-adaptive millimeter-wave scoliosis screening device provided by this invention, using concrete examples (e.g.) Figure 1 (As shown) and its technical effects. The equipment consists of: an equipment base 4, a platform 9 and a movable chassis 10. A lifting screw mechanism is fixedly installed on the equipment base 4. A millimeter-wave component 6 is fixedly installed on the front side of the lifting screw mechanism. An optical camera mounting bracket 7 is fixedly installed on the top of the lifting screw mechanism. An optical camera 8 is fixedly installed on the optical camera mounting bracket 7.

[0045] The platform 9 is used to detect whether the standing posture of the person being tested meets the requirements and sends a detection signal to the movable housing 10. After the movable housing 10 determines that the standing posture of the person being tested meets the requirements, it collects the height and back data of the person being tested through the optical camera 8, and drives the millimeter wave component 6 to adjust to the corresponding back position through the drive of the lifting screw mechanism. Under the drive of the movable housing 10, the millimeter wave component 6 emits millimeter wave signals to the back position and receives the echo signals and sends them back to the movable housing 10. The movable housing 10 generates a millimeter wave image based on the echo signals and performs scoliosis analysis.

[0046] I. Liftable Screw Mechanism

[0047] like Figures 2 to 4 As shown, the lifting screw mechanism includes a housing assembly 1, a screw drive assembly 2, and a motor 3;

[0048] The housing assembly 1 includes a back support 101, a front housing 102, a rear housing 105, a synchronous pulley protective housing 103, a square single bearing seat mounting plate 104, and a motor protective housing 5;

[0049] The lead screw drive assembly 2 includes a lead screw 201, a T-shaped single bearing seat 202, a slide rail 203, a millimeter wave component mounting base 204, a T-shaped double bearing seat 205, a lock nut 206, a coupling 207, a pulley shaft 208, a square single bearing seat 209, a synchronous belt 210, a synchronous pulley 211, a photoelectric switch 212, a photoelectric switch baffle 213, and a silicone anti-collision plate 214.

[0050] like Figure 3 As shown, the threaded end of the lead screw 201 serves as the fixed end. The fixed end of the lead screw 201 is assembled in a T-shaped double bearing seat 205 with double rolling bearings to complete the radial fixation of the fixed end. One side of the fixed end of the lead screw 201 is axially locked by the threaded engagement of the locking nut 206 with the lead screw 201, and the other side is axially limited by the integrally formed shoulder on the lead screw 201 to complete the axial fixation of the fixed end.

[0051] The other end of the lead screw 201 serves as a support end. The support end of the lead screw 201 is assembled in a T-shaped single bearing seat 202 with a single rolling bearing. Only the support end is radially fixed (the position of the lead screw 201 remains unchanged during the movement through the above-mentioned fixing method). The T-shaped double bearing seat 205 and the T-shaped single bearing seat 202 are both fixedly installed in the cavity of the rear housing 105.

[0052] Slide rails 203 are fixedly installed on both the left and right sides of the cavity inside the rear housing 105. The millimeter wave component mounting base 204 is threadedly connected to the lead screw 201 and slidably connected to the slide rail 203. The millimeter wave component 6 is fixedly installed on the millimeter wave component mounting base 204, so that the lead screw 201 rotates and drives the millimeter wave component 6 to move up and down linearly along the slide rail 203.

[0053] like Figure 3 As shown, a coupling 207 is symmetrically provided at the bottom of the fixed end of the lead screw 201 (the coupling 207 can compensate for the relative displacement between the rotation center of the synchronous pulley 211 and the rotation center of the lead screw 201, as well as between the rotation center of the synchronous pulley 211 and the rotation center of the motor 3 during the movement). The bottom of the fixed end of the lead screw 201 is equipped with a coupling 207, a pulley shaft 208 and a synchronous pulley 211. The drive shaft of the motor 3 is also equipped with a coupling 207, a pulley shaft 208 and a synchronous pulley 211. The two synchronous pulleys 211 are connected by a synchronous belt 210.

[0054] A motor protective shell 5 is fixedly installed on the equipment base 4. The pulley shaft 208 and the synchronous pulley 211 are both installed and connected to a square single bearing seat 209 with a single rolling bearing. The square single bearing seat 209 is fixedly installed on the square single bearing seat mounting plate 104. The synchronous pulley 211 is provided with a synchronous pulley protective shell 103.

[0055] like Figure 3 As shown, photoelectric switches 212 are fixedly installed at both the upper and lower ends of the same side of the lead screw 201. A photoelectric switch baffle 213 that cooperates with the photoelectric switch 212 is fixedly installed on the millimeter wave component mounting base 204. It is used to control the start and end points of the stroke of the liftable lead screw mechanism. When the liftable lead screw mechanism moves to the start or end point, the photoelectric switch baffle 213 will trigger the corresponding photoelectric switch 212 to prevent the millimeter wave component mounting base 204 from moving further and avoid equipment collision.

[0056] Silicone anti-collision plates 214 are fixedly installed on the top, bottom, and left and right sides of the housing assembly 1. When the photoelectric switch 212 fails, the travel of the lifting screw mechanism will exceed the specified travel. The silicone anti-collision plates 214, as a physical collision protection device, will force the lifting screw mechanism to stop moving to avoid damage to the equipment.

[0057] 2. Platform

[0058] like Figure 5 As shown, the platform 9 includes a platform housing 901 and a pressure sensor array 902, which is used to detect whether the standing posture of the person being tested meets the requirements. The pressure sensor array 902 sends a detection signal to the movable chassis 10.

[0059] III. Removable Chassis

[0060] like Figure 6 As shown, the movable chassis 10 includes a movable chassis shell 1001, a display 1002, a frequency controller 1003, a switch 1004, a servo driver 1005, a serial server 1006, a signal processor 1007, and an industrial computer 1008, which are used to control the adaptive human height movement of the lifting screw mechanism, the operation of the millimeter wave component 6, and the processing and analysis of signals.

[0061] In the technical solution of this application, the signal processor 1007 receives the height and back data of the person to be tested collected by the optical camera 8, and sends control commands to the servo driver 1005 to drive the motor 3, and uses the liftable screw mechanism to drive the millimeter wave component 6 to adjust to the corresponding back position.

[0062] The signal processor 1007 sends an operation command to the frequency controller 1003, which in turn sends a millimeter-wave signal to the millimeter-wave component 6. Upon receiving the millimeter-wave signal, the millimeter-wave component 6 begins to operate. The intermediate frequency signal output by the millimeter-wave component 6 is sampled by the ADC and converted into an IQ signal, which is then transmitted back to the signal processor 1007. The industrial control computer 1008 receives the IQ signal sent by the signal processor 1007, performs image reconstruction to generate a millimeter-wave image, and displays it on the display 1002. Simultaneously, it performs scoliosis analysis on the millimeter-wave image and generates an analysis report.

[0063] In this technical solution, the total height of the adjustable lead screw mechanism is 1574mm, the movable stroke is 1100mm, and the height of the millimeter-wave component 6 is 750mm, covering a maximum human height of 1850mm, which can meet the scoliosis screening needs of most people. At the same time, the various modules and components of the equipment are small in size, lightweight, easy to transport, and convenient to assemble on-site.

[0064] Based on the aforementioned disclosed millimeter-wave scoliosis screening device that adapts to human height, this invention also discloses a method for operating the millimeter-wave scoliosis screening device that adapts to human height, comprising the following steps:

[0065] S1. When the person to be tested stands on the platform 9 and the posture meets the requirements, the optical camera 8 collects the height and back data of the person to be tested and sends them to the signal processor 1007 inside the movable chassis 10.

[0066] S2, Signal processor 1007 sends control commands to servo driver 1005 to drive motor 3, and uses liftable screw mechanism to drive millimeter wave component 6 to adjust to the corresponding back position;

[0067] S3. When the standing posture of the person being tested meets the requirements and the millimeter wave component 6 is adjusted to the corresponding back position, the signal processor 1007 sends an operation command to the frequency controller 1003, the frequency controller 1003 sends a millimeter wave signal to the millimeter wave component 6, and the millimeter wave component 6 starts working after receiving the millimeter wave signal.

[0068] When S4 and millimeter-wave component 6 are working, the intermediate frequency signal output is sampled by ADC, converted into IQ signal, and then sent back to signal processor 1007;

[0069] S5. The industrial control computer 1008 receives the IQ signal sent by the signal processor 1007, performs image reconstruction to generate a millimeter-wave image, and displays it on the display 1002. At the same time, it performs scoliosis analysis on the millimeter-wave image and generates an analysis report.

[0070] Specifically, the movable chassis 10 includes a movable chassis shell 1001, a display 1002, a frequency controller 1003, a switch 1004, a servo driver 1005, a serial server 1006, a signal processor 1007, and an industrial computer 1008, used to control the adaptive human height movement of the lifting screw mechanism, the operation of the millimeter wave component 6, and the processing and analysis of signals.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
