Description

Technical Field

[0001] This invention relates to the field of camera installation technology, specifically to a single-bar training camera positioning device and its control system. Background Technology

[0002] In group horizontal bar training and testing in settings such as the military, schools, and sports stadiums, it is necessary to simultaneously monitor multiple sets of horizontal bars (usually arranged at a standard 1.5m interval) and multiple trainees using cameras to fully capture key details of movements such as pull-ups and bent-arm hangs, providing objective image evidence for training and testing scores. The installation distance between the camera and the horizontal bar is a core influencing factor; the distance must be precisely matched to the camera's field of view to simultaneously cover 3-6 sets of horizontal bars without compromising the details of the trainees' movements.

[0003] Currently, distance positioning for horizontal bar training cameras mainly relies on two methods, both of which have drawbacks: First, direct measurement with a measuring tape is used. Workers must first determine the reference point of the horizontal bar array (such as the first horizontal bar column) as the starting point, then pull the measuring tape to a preset distance to mark the camera installation point (end point). However, this method lacks a rigid positioning structure. Pulling the measuring tape can easily cause the starting point to shift due to hand tremors or ground obstacles (such as the measuring tape hook slipping off the horizontal bar column), or the end point marker to shift due to personnel movement, ultimately leading to measurement deviations and failing to meet the requirements for field of view coverage. Second, to avoid starting or ending point offset issues, in some scenarios, a chalk line is first used to determine the connection between the horizontal bar reference and the camera installation point, and then the distance is measured along the chalk line with a measuring tape. While this ensures straight-line alignment between the starting and ending points, the chalk line process requires multiple people (one to hold the chalk line, one to pull it for positioning), and positioning in a single location is time-consuming.

[0004] In addition, laser rangefinders have been used in some scenarios to improve efficiency. However, laser ranging relies on a specific reflection point, and since there is no pre-set reflection target before the camera is installed, staff must hold a reflector and move it repeatedly between the horizontal bar and the camera installation point while observing the rangefinder readings until the distance between the reflection point and the rangefinder matches the optimal value calculated earlier. Only then is the reflection point marked as the camera installation point. During this process, the reflector is prone to displacement due to hand movement, and the angle of the reflector needs to be repeatedly adjusted to ensure accurate laser reflection. In practice, the efficiency is even lower than that of measuring with a tape measure.

[0005] In summary, existing single-bar training camera distance positioning methods either suffer from deviations due to a lack of rigid reference or inefficiency due to cumbersome operating procedures, failing to meet the requirements for accurate, fast, and stable positioning. Therefore, there is an urgent need for an integrated positioning device and control system to solve the problems of starting or ending point offsets and complex operations in distance measurement, and to provide a reliable distance reference for camera installation. Summary of the Invention

[0006] The purpose of this invention is to provide a single-bar training camera positioning device and its control system to solve the problems mentioned in the background art.

[0007] In view of the above problems, the technical solution proposed by the present invention is as follows:

[0008] A single-bar training and testing camera positioning device includes a fixed component and a movable component. The fixed component includes a fixed base placed at the starting position of the measurement. A support rod is mounted on the top surface of the fixed base, and a fixed plate is fixed to the top of the support rod. A connector, an infrared receiver, and a buzzer are mounted on the top surface of the fixed plate. The movable component includes a movable base. Four sets of directional wheels are mounted on the bottom surface of the movable base. Three sets of support columns are mounted on the top surface of the movable base. A base is mounted on the top surface of the support columns. A movable plate is slidably connected to the top surface of the base. A pair of connecting blocks and an infrared transmitter are mounted on the top surface of the movable plate. The pair of connecting blocks rotate between each other. A rotating shaft is connected, and a winch is mounted on the outside of the shaft. A measuring tape is wound around the outside of the winch, and the zero-scale end of the measuring tape is connected to a connector. A driving component is installed inside the base. A spray nozzle is located below the movable disc. The driving component drives the movable disc and the spray nozzle to move horizontally synchronously. The movable seat has a slot, and the bottom end of the spray nozzle slides within the slot. The fixed seat serves as the base for the fixed component and can be stably placed at the starting position of the measurement, providing a fixed reference for subsequent positioning. A support rod supports the fixed plate, positioning the connector, infrared receiver, and buzzer on the fixed plate at a suitable height for easy cooperation with the movable component. The connector and... The zero-scale end of the measuring tape is connected to ensure a fixed starting point for measurement and prevent starting point deviation. An infrared receiver, in conjunction with an infrared transmitter on the movable plate, detects whether the fixed and movable parts are aligned, ensuring accurate measurement direction. A buzzer, working with the infrared receiver, provides an alert when either component deviates, allowing staff to be promptly informed. Four sets of directional wheels on the bottom of the movable base allow for stable and convenient movement of the movable part, facilitating position adjustments, and ensuring the wheels maintain a straight line, preventing tape measure deviation. Three support columns support the base, ensuring stable installation of the base and its upper components. The base slides onto the movable plate, and in conjunction with the drive mechanism, it can move the movable part... The moving plate, its connecting blocks, rotating shaft, winch, measuring tape, and infrared transmitter move synchronously, while the driving component drives the spray nozzle to move synchronously, ensuring that the marked position of the spray nozzle matches the end point measured by the measuring tape. A pair of connecting blocks support the rotating shaft, enabling it to rotate stably, which in turn drives the winch to rotate, thus enabling the measuring tape to be extended and retracted. The winch winds the measuring tape, and by rotating the winch, the extension length of the measuring tape can be precisely controlled to achieve distance measurement. The slot provides sliding space for the bottom of the spray nozzle, ensuring smooth movement of the spray nozzle. Through the cooperation of these components, the installation point of the single-bar training camera is accurately positioned, providing a reliable distance reference for camera installation.

[0009] Furthermore, one of the connecting blocks has a connecting groove at its top, and a connecting strip is rotatably connected within the connecting groove. An arc-shaped toothed plate is installed on the bottom surface of the connecting strip. One end of the rotating shaft passes through one of the connecting blocks and is connected to a toothed disc. The arc-shaped toothed plate can engage with the toothed disc. The connecting groove at the top of the connecting block provides rotational installation space for the connecting strip, allowing it to rotate flexibly within the groove. The arc-shaped toothed plate installed on the bottom surface of the connecting strip cooperates with the toothed disc at one end of the rotating shaft. When the arc-shaped toothed plate engages with the toothed disc, it restricts the rotation of the toothed disc, thereby restricting the rotation of the rotating shaft. This prevents the measuring tape length from changing due to accidental rotation of the winch during measurement, ensuring the accuracy of the measured distance. When the measuring tape length needs to be adjusted, rotating the connecting strip separates the arc-shaped toothed plate from the toothed disc, allowing the rotating shaft to be rotated to adjust the winch. Through this cooperation, controllability of the winch rotation is achieved, further improving the stability and accuracy of distance measurement.

[0010] Furthermore, the top surface of the base has a first sliding groove, and the driving component includes a threaded rod rotatably installed in the first sliding groove. A first slider is threadedly connected to the outer side of the threaded rod, and the first slider slides within the first sliding groove. The movable disc is installed on the top surface of the first slider. A first connecting shaft is coaxially connected to the free end of the threaded rod, and the free end of the first connecting shaft is rotatably connected to the wall of the first sliding groove. A driven bevel gear is installed on the outer side of the first connecting shaft. A second connecting shaft is rotatably connected inside the base, and a driving bevel gear is installed on the outer side of the second connecting shaft. The driving bevel gear and the driven bevel gear mesh. A handwheel is provided on the outer side of the base, and the handwheel and the second connecting shaft are coaxially connected. The first sliding groove on the top surface of the base provides a sliding track for the first slider, ensuring the stability of the first slider's movement direction, thereby ensuring the movable disc... The movement direction is accurate; the threaded rod in the drive component is threadedly engaged with the first slider, and when the threaded rod rotates, it drives the first slider to slide precisely along the first groove. Since the movable plate is installed on the top surface of the first slider, the movable plate can move precisely; the first connecting shaft is coaxially connected to the threaded rod and rotatably connected to the wall of the first groove, which not only supports the threaded rod but also drives it to rotate synchronously; the driven bevel gear on the outside of the first connecting shaft meshes with the driving bevel gear on the outside of the second connecting shaft, transmitting the rotation of the second connecting shaft to the first connecting shaft, thus changing the direction of power; the second connecting shaft is coaxially connected to the handwheel on the outside of the base, and the operator can drive the second connecting shaft to rotate by turning the handwheel, which is convenient and does not require complicated equipment. Through the cooperation of these components, the precise and convenient movement of the movable plate is achieved, which provides a guarantee for the accurate marking of the camera installation point on the subsequent spray pipe.

[0011] Further, the spraying component includes a connecting pipe, a second slider is mounted at the top of the connecting pipe, the second slider is mounted on the bottom surface of the first slider, the bottom surface of the base has a second groove, the second groove and the first groove are connected, the second slider slides within the second groove, the connecting pipe has a storage cavity for storing marking paint, a one-way valve is mounted on the outside of the connecting pipe, the one-way valve is connected to the storage cavity, and the connection point is near the top of the storage cavity, the bottom end of the connecting pipe has a manual shut-off valve, the manual shut-off valve is connected to the storage cavity, the free end of the manual shut-off valve is connected to a spray head, the spray head slides within the groove, the second slider at the top of the connecting pipe is mounted on the bottom surface of the first slider, and the second slider slides within the second groove on the bottom surface of the base, since the second groove is connected to the first groove... The system allows the first slider to move synchronously with the second slider, which in turn moves the connecting pipe synchronously, ensuring that the connecting pipe moves in unison with the movable disc and guaranteeing accurate marking. The storage chamber inside the connecting pipe stores marking paint, providing material for the marking. A one-way valve on the outside of the connecting pipe connects to the storage chamber and is located at the top of the chamber, preventing backflow of paint and facilitating paint replenishment. A manual shut-off valve at the bottom of the connecting pipe connects to the storage chamber, allowing operators to control the flow of paint. A nozzle at the free end of the manual shut-off valve sprays paint evenly, creating clear markings on the ground. The nozzle slides smoothly within the slot, ensuring smooth movement. Through the coordination of these components, precise marking of the camera installation point is achieved, avoiding deviations caused by manual marking.

[0012] Furthermore, the extension line of the nozzle axis passes through the center point of the winch axis, ensuring that the marked position of the nozzle and the end point measured by the tape measure on the winch are on the same straight line. This avoids discrepancies between the marked position and the actual measured end point due to positional deviations between the nozzle and the winch, ensuring that the distance measured by the tape measure is the distance from the starting point to the nozzle marked point. This further improves the accuracy of the camera installation point positioning, guaranteeing that the camera can accurately cover the preset single-bar area after installation.

[0013] Furthermore, both ends of the first slide groove have grooves on both sides of the threaded rod, and pins are rotatably connected in each groove. A dustproof belt is connected between the four sets of pins. The base has a pair of through slots inside, which connect the upper and lower grooves. The dustproof belt slides in the grooves and is connected to the first slider. The grooves on both sides of the threaded rod at both ends of the first slide groove provide installation space for the pins. The four sets of pins support the dustproof belt, allowing it to be stably installed in the first slide groove. The dustproof belt is connected to the first slider and slides in the groove. When the first slider moves along the first slide groove, the dustproof belt moves synchronously with the first slider, always covering the opening of the first slide groove to prevent dust, sand, and other impurities from entering the first slide groove. The through slots inside the base connect the upper and lower grooves, providing a channel for the movement of the dustproof belt and preventing it from being obstructed. Through this cooperation, the threaded rod and the first slider in the first slide groove are protected, preventing impurities from affecting their fit accuracy and service life, ensuring the long-term stable operation of the drive component, and guaranteeing the durability of the positioning device.

[0014] Furthermore, the dustproof belt and the first slide groove are of equal width, ensuring that the dustproof belt completely covers the opening width of the first slide groove without any gaps in the width direction. This prevents dust and impurities from entering the first slide groove through the width gap between the dustproof belt and the first slide groove, further improving the dustproof effect and better protecting the threaded rod and the first slider inside the first slide groove. This ensures that the two maintain a good fit for a long time, guarantees the stable operation of the drive component, and extends the service life of the positioning device.

[0015] Furthermore, the infrared receiver, infrared transmitter, and buzzer are all equipped with independently powered batteries, which are integrated inside the housings of the infrared receiver, infrared transmitter, and buzzer, respectively. The infrared receiver and buzzer are electrically connected. The independent power supply batteries for each infrared receiver, infrared transmitter, and buzzer, integrated within their respective housings, eliminate the need for external power lines. This avoids the problem of tangled wiring affecting the movement of the movable seat via the directional wheels and the operation of the drive components by staff. It also ensures that the infrared receiver, infrared transmitter, and buzzer can still function normally in outdoor training environments without external power sources. The continuous operation improves the portability of the positioning device and its applicability in different scenarios. The infrared receiver and buzzer are electrically connected. When the infrared receiver does not receive the infrared signal emitted by the infrared transmitter, it will control the buzzer to sound an alarm, reminding the staff that the fixed part and the moving part are not in a straight line. The staff does not need to continuously observe the indicator light status of the infrared receiver, which simplifies the operation process and helps the staff to quickly adjust the position of the moving part until the buzzer stops sounding. This ensures that the fixed part and the moving part are quickly aligned, ensures the accuracy of the measuring tape's direction, and avoids incorrect positioning of the camera installation point due to directional deviation.

[0016] On the other hand, this invention also proposes a single-bar training camera positioning device, including a column installed at a marked location on a spray nozzle. A bracket is mounted on the side of the column near its top, and a pan-tilt unit is mounted on the free end of the bracket for fixing a smart vision camera. An equipment box is mounted on the side of the column near its middle section, housing a PoE switch. A mounting bracket is mounted on the side of the bracket for fixing a control panel. The control panel, pan-tilt unit, and smart vision camera are connected via a network cable and the PoE switch. The column, installed at the marked location on the spray nozzle, provides a stable mounting foundation for the bracket, equipment box, and other components, ensuring that the positions of each component are consistent with the camera mounting point. The bracket on the top side of the column supports the pan-tilt unit, placing it at a suitable height. The system features a fixed angle for the smart vision camera, ensuring it covers the pre-defined horizontal bar area. The pan-tilt unit secures the camera and allows for angle adjustment, enabling precise aiming at the training area and capturing detailed movements of the trainees. A device box on the side of the central section protects the internal PoE switch from external environmental damage. The PoE switch powers the control panel, pan-tilt unit, and smart vision camera via network cable, eliminating the need for separate power lines and simplifying wiring. A mounting bracket on the side of the support secures the control panel, allowing staff to adjust the pan-tilt angle and view camera footage. These components work together to ensure stable installation and convenient control of the smart vision camera, guaranteeing effective monitoring of the horizontal bar training process.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The fixed base serves as a rigid fixed reference and is placed at the starting position of the measurement. Its top connector is fixedly connected to the zero mark end of the measuring tape, ensuring that the starting point of the measurement is always stable and avoiding the offset caused by the hook slipping during traditional measuring tape measurements. At the same time, the infrared transmitter and infrared receiver work together, and a buzzer indicates when they are aligned, ensuring that the fixed part and the moving part are in the same straight line, avoiding the offset of the measurement direction, and further ensuring the stability of the straight line reference from the starting point to the end point.

[0019] Second, the directional wheels of the movable base make it easy to move the movable parts without the need for multiple people to carry them; the movable plate and spray pipe can be moved by turning the handwheel, and with the aiming prompt of the buzzer, a single person can complete the positioning operation without the need for multiple people to work together to draw lines or repeatedly adjust the reflector; the PoE switch in the control system integrates power supply and data transmission, simplifies wiring, and the control panel allows for convenient control of the pan-tilt unit and camera. The overall operation process is simple and efficient, and compared with traditional tape measure measurement and laser rangefinder, it significantly shortens the positioning and installation time.

[0029] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 - Figure 7 This invention provides a technical solution: a single-bar training and testing camera positioning device, comprising a fixed component and a movable component. The fixed component includes a fixed base 1 placed at the starting position of the measurement. A support rod 2 is installed on the top surface of the fixed base 1, and a fixed plate 3 is fixed to the top of the support rod 2. A connector 4, an infrared receiver 5, and a buzzer are installed on the top surface of the fixed plate 3. The movable component includes a movable base 6. Four sets of directional wheels 7 are installed on the bottom surface of the movable base 6. Three sets of support columns 8 are installed on the top surface of the movable base 6. A base 9 is installed on the top surface of the support columns 8. A movable plate 14 is slidably connected to the top surface of the base 9. A [missing information - likely a device or component] is installed on the top surface of the movable plate 14. A rotating shaft 20 rotatably connects the connecting block 15 and the infrared emitter 18. A winch 16 is mounted on the outside of the rotating shaft 20, and a measuring tape 17 is wound around the outside of the winch 16. The zero-scale end of the measuring tape 17 is connected to the connector 4. A driving component is installed inside the base 9. A spray pipe is provided below the movable disc 14. The driving component drives the movable disc 14 and the spray pipe to move horizontally synchronously. The movable seat 6 has a slot 10, and the bottom end of the spray pipe slides in the slot 10. First, the fixed seat 1 is placed in the measurement starting position and fixed. The support rod 2 on the top surface of the fixed seat 1 supports the fixed plate 3, so that the connection... Head 4, infrared receiver 5, and buzzer are kept at a suitable height; then, the shaft 20 between the connecting blocks 15 on the movable plate 14 is rotated, the shaft 20 drives the winch 16 to rotate, releasing the wound measuring tape 17, and fixing the zero mark end of the measuring tape 17 to the connecting head 4; the operator pushes the movable seat 6, the four sets of directional wheels 7 on the bottom of the movable seat 6 roll, driving the movable seat 6 and the supporting column 8, base 9, movable plate 14, etc., to move as a whole. During the movement, the scale of the measuring tape 17 is observed. When the scale reaches the distance between the preset camera installation point and the starting point, the movement of the movable seat 6 is stopped, and the position of the movable seat 6 is kept fixed. During this process, the infrared transmitter 18 and infrared receiver 5 are turned on. The infrared transmitter 18 emits an infrared signal. At this time, due to the positional deviation of the movable plate 14, the infrared receiver 5 cannot receive the signal, and the buzzer triggers an alarm. The operator operates the drive component to move the movable plate 14 until the infrared receiver 5 receives the signal from the infrared transmitter 18, and the buzzer stops alarming. At this time, the infrared line is accurately aligned, the measurement direction is accurate, and when the infrared line is aligned and the scale reaches the distance between the preset camera installation point and the starting point, the spray pipe is opened to form a mark of the camera installation point, completing the positioning operation.

[0031] In one embodiment of the present invention, a connecting groove is further provided at the top of one of the connecting blocks 15, and a connecting strip 22 is rotatably connected in the connecting groove. An arc-shaped toothed plate 23 is installed on the bottom surface of the connecting strip 22. One end of the rotating shaft 20 passes through one of the connecting blocks 15 and is connected to a toothed disc 21. The arc-shaped toothed plate 23 can engage with the toothed disc 21. When it is necessary to fix the length of the measuring tape 17 to prevent the winch 16 from rotating accidentally, the operator rotates the connecting strip 22 in the connecting groove of the connecting block 15. The connecting strip 22 rotates around the rotation point of the connecting groove, driving the arc-shaped toothed plate 23 on the bottom surface to move towards the toothed disc 21 until the arc-shaped toothed plate 23 is fully engaged with the toothed disc 21 on the rotating shaft 20. At this time, the toothed disc 21 is restricted from rotating. Since the toothed disc 21 is connected to the rotating shaft 20, the rotating shaft 20 cannot rotate either, and thus the winch 16 cannot rotate, and the length of the measuring tape 17 remains fixed. When it is necessary to adjust the length of the measuring tape 17, when the winch 16 is rotated, the operator rotates the connecting bar 22 in the opposite direction. The connecting bar 22 drives the arc-shaped toothed plate 23 away from the toothed disc 21, so that the arc-shaped toothed plate 23 is separated from the toothed disc 21, releasing the restriction on the toothed disc 21 and the rotating shaft 20. Then the rotating shaft 20 can rotate, and the rotating shaft 20 drives the winch 16 to rotate, realizing the winding and unwinding of the measuring tape 17. After adjusting to the required length, the connecting bar 22 is rotated again to make the arc-shaped toothed plate 23 engage with the toothed disc 21, fixing the length of the measuring tape 17.

[0032] As an embodiment of the present invention, the top surface of the base 9 further includes a first sliding groove 24. The driving component includes a threaded rod 28 rotatably mounted in the first sliding groove 24. A first slider 25 is threadedly connected to the outer side of the threaded rod 28. The first slider 25 slides within the first sliding groove 24. A movable disc 14 is mounted on the top surface of the first slider 25. A first connecting shaft 30 is coaxially connected to the free end of the threaded rod 28, and the free end of the first connecting shaft 30 is rotatably connected to the wall of the first sliding groove 24. A driven bevel gear 31 is mounted on the outer side of the first connecting shaft 30. A second connecting shaft is rotatably connected inside the base 9. A driving bevel gear 32 is mounted on the outer side of the second connecting shaft. The driving bevel gear 32 and the driven bevel gear 31 mesh. A handwheel 19 is provided on the outer side of the base 9. The handwheel 19 and the second connecting shaft are coaxially connected. When it is necessary to move the movable disc 14, the operator rotates the handwheel 19 on the outer side of the base 9. When the second connecting shaft, which is coaxially connected, rotates, the driving bevel gear 32 on the outer side of the second connecting shaft rotates synchronously with the second connecting shaft. Since the driving bevel gear 32 meshes with the driven bevel gear 31 on the outer side of the first connecting shaft 30, the driving bevel gear 32 drives the driven bevel gear 31 to rotate, and the driven bevel gear 31 drives the first connecting shaft 30 to rotate. The first connecting shaft 30 is coaxially connected with the threaded rod 28, and the free end of the first connecting shaft 30 is rotatably connected to the wall of the first slide groove 24. Therefore, the first connecting shaft 30 drives the threaded rod 28 to rotate in the first slide groove 24. The threaded rod 28 is threadedly engaged with the first slider 25. When the threaded rod 28 rotates, the first slider 25 slides along the axis of the threaded rod 28 under the restriction of the first slide groove 24. Since the movable disk 14 is installed on the top surface of the first slider 25, the first slider 25 drives the movable disk 14 to move synchronously until the movable disk 14 moves to the desired position, and the handwheel 19 is stopped.

[0033] As an embodiment of the present invention, the spraying component further includes a connecting pipe 11, a second slider 29 is mounted on the top end of the connecting pipe 11, the second slider 29 is mounted on the bottom surface of the first slider 25, the bottom surface of the base 9 has a second groove 27, the second groove 27 communicates with the first groove 24, the second slider 29 slides in the second groove 27, the connecting pipe 11 has a storage cavity 36 for storing marking paint, a one-way valve 37 is mounted on the outside of the connecting pipe 11, the one-way valve 37 communicates with the storage cavity 36, and the communication point is close to the top end of the storage cavity 36, a manual shut-off valve 12 is mounted on the bottom end of the connecting pipe 11, the manual shut-off valve 12 communicates with the storage cavity 36, the free end of the manual shut-off valve 12 communicates with a nozzle 13, the nozzle 13 slides in the slot 10, and before the movable disc 14 moves, it first sprays paint into the storage cavity 36 through the one-way valve 37 on the outside of the connecting pipe 11. The marking paint is injected into the internal cavity. The one-way valve 37 prevents backflow of the paint after injection. After injection, the one-way valve 37 automatically closes. When the movable disc 14 moves under the drive of the driving component, the second slider 29 on the bottom surface of the first slider 25 slides synchronously in the second sliding groove 27 on the bottom surface of the base 9. The second slider 29 drives the connecting pipe 11 to move. The manual shut-off valve 12 and the nozzle 13 at the bottom of the connecting pipe 11 move synchronously with the connecting pipe 11. The nozzle 13 slides in the slot 10 of the movable seat 6. When the movable disc 14 and the connecting pipe 11 move to the position corresponding to the camera installation point, the operator opens the manual shut-off valve 12. The marking paint in the storage cavity 36 flows to the nozzle 13 under the action of gravity through the manual shut-off valve 12, and is then evenly sprayed onto the ground by the nozzle 13 to form a mark. After the marking is completed, the manual shut-off valve 12 is closed to stop the paint spraying, thus completing the marking operation of the camera installation point.

[0034] As an embodiment of the present invention, the extension line of the nozzle 13 axis passes through the center point of the winch 16 axis. Since the extension line of the nozzle 13 axis passes through the center point of the winch 16 axis, when the winch 16 releases the measuring tape 17 to measure the distance, the measuring tape 17 extends from the center point of the winch 16 axis and measures the distance from the connector 4 to the center point of the winch 16 axis. The position of the nozzle 13 mark is on its axis extension line, that is, on the straight line where the center point of the winch 16 axis is located. Therefore, the distance measured by the measuring tape 17 is completely consistent with the distance from the starting point to the mark point of the nozzle 13, and there is no positional deviation. When the nozzle 13 sprays the paint mark, the mark point is the accurate endpoint of the measurement by the measuring tape 17, that is, the precise installation point of the camera.

[0035] In one embodiment of the present invention, the first sliding groove 24 is further provided with grooves 33 on both sides of the threaded rod 28 at both ends. Pins 34 are rotatably connected within each groove 33. A dustproof belt 26 is connected between the four sets of pins 34. A pair of through grooves 35 are provided inside the base 9, connecting the upper and lower grooves 33. The dustproof belt 26 slides within the grooves 33. The dustproof belt 26 is connected to the first slider 25. When the first slider 25 slides along the first sliding groove 24 under the action of the threaded rod 28, the dustproof belt 26 is connected to the first slider 25, causing the first slider 25 to drive the dustproof belt 26 to slide within the grooves 33. The four sets of pins 34 within the grooves 33 move with the dustproof belt 26. The sliding and rotating mechanism provides support and guidance for the dustproof belt 26, ensuring its smooth movement. The through groove 35 inside the base 9 connects the upper and lower grooves 33, allowing the dustproof belt 26 to move between them. This ensures that the dustproof belt 26 completely covers the opening of the first slide groove 24. Regardless of the position of the first slider 25, the dustproof belt 26 can block the portion of the first slide groove 24 not covered by the first slider 25, preventing dust, sand, and other impurities from entering the first slide groove 24. This also prevents impurities from adhering to the surface of the threaded rod 28 or entering the meshing point between the first slider 25 and the threaded rod 28, ensuring the fitting accuracy between the threaded rod 28 and the first slider 25 and ensuring the normal operation of the drive components.

[0036] As an embodiment of the present invention, the dustproof belt 26 and the first slide groove 24 are of equal width. Because the dustproof belt 26 and the first slide groove 24 are of equal width, when the dustproof belt 26 covers the opening of the first slide groove 24, the width of the dustproof belt 26 is completely consistent with the opening width of the first slide groove 24, and the two side edges of the dustproof belt 26 can be aligned with the two side edges of the first slide groove 24 without any gaps. When the first slider 25 moves the dustproof belt 26, no matter where the dustproof belt 26 is, its width direction always matches the opening width of the first slide groove 24. Dust and impurities cannot enter the first slide groove 24 from the gap in the width direction, but can only be blocked to the outside by the dustproof belt 26, thereby completely protecting the threaded rod 28 and the first slider 25 inside the first slide groove 24.

[0037] As an embodiment of the present invention, the infrared receiver 5, the infrared transmitter 18, and the buzzer are each equipped with an independently powered battery. The batteries are integrated inside the housings of the infrared receiver 5, the infrared transmitter 18, and the buzzer, respectively. The infrared receiver 5 and the buzzer are electrically connected. The infrared transmitter 18 emits infrared signals when powered by the battery, and the infrared receiver 5 continuously receives signals when powered by the battery. If no signal is received, the infrared receiver 5 transmits an electrical signal to the buzzer, triggering an alarm and prompting the operator to fine-tune the drive mechanism. When the drive mechanism moves the infrared transmitter 18 to the alignment position, the infrared receiver 5 receives the signal and immediately stops transmitting electrical signals to the buzzer, and the buzzer stops sounding the alarm. At this time, the infrared alignment is complete.
