[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) In this invention, a fixed target is used to locate one end of the target, and a movable target is used to locate the other end of the target. By driving the movable target away from the fixed target, the width of a narrow target can be detected. By driving the movable target away from the fixed target, the movable target can be rotated to locate the target at a more distant position, and the length of a long target can be detected. (2) In this invention, the toothed plate and the connecting plate are connected by meshing teeth. When the driving toothed plate moves away from the fixed target, the movable target can be controlled to move away from the fixed target. When the driving toothed plate moves towards the fixed target, the movable target can be controlled to rotate away from the fixed target, which facilitates the control of two detection methods. (3) In this invention, two distance measuring components are symmetrically arranged on both sides of the slider. The compression spring is compressed by the movement of the pressure plate, and the elastic force of the compression spring is detected by the pressure sensor. Thus, the moving distance of the toothed plate can be detected, which makes it convenient to calculate the moving distance of the movable target and the rotation angle of the movable target, and thus makes it convenient to detect the target width and length. (4) In this invention, before the slider moves, the locking block is first controlled to disengage from the locking groove, so that the slider can move before the toothed plate, so that the contact point can make contact with the first conductive strip or the second conductive strip before the toothed plate moves, so that the first electromagnet is energized, and the movable target can move or rotate. At the same time, when the toothed plate moves back, the slider moves back before the toothed plate, so that the locking block engages with the locking groove, and when the slider moves back to the original position, the movable target can also move back to the original position. (5) In this invention, when the contact point contacts the first conductive strip, the first electromagnet attracts the first magnetic block, causing the lever to move upward and engage with the first slot, thereby securing the movable target and the sliding frame. This facilitates the toothed plate moving the movable target away from the fixed target, making it easier to detect the width of narrow targets. When the contact point contacts the second conductive strip, the first electromagnet repulses the first magnetic block, causing the lever to engage with the second slot, thereby securing the sliding frame and the horizontal frame. This facilitates the toothed plate rotating the movable target away from the fixed target, making it easier to detect the length of long targets. Attached Figure Description

[0022] The active drive assembly 5 includes an inner slide groove 501 opened inside the horizontal frame 1. An outer slide groove 502 is opened on the side of the inner slide groove 501 near the active target 301. One end of the outer slide groove 502 extends through to the outside of the end of the horizontal frame 1 near the fixed target 201. A movable rotating component 503 is slidably installed inside the outer slide groove 502. The movable rotating component 503 includes a toothed plate 5031 slidably mounted inside the outer slide groove 502. The toothed plate 5031 is engaged with the teeth 304 on the connecting plate 303. When the toothed plate 5031 moves away from the fixed target 201, it can control the movable target 301 to move away from the fixed target 201. Conversely, when the toothed plate 5031 moves towards the fixed target 201, it can control the movable target 301 to rotate away from the fixed target 201, facilitating control of two detection methods. The toothed plate 5031 is engaged with the teeth 304 on the connecting plate 303. A slider 5032 is slidably mounted inside the inner slide groove 501, and a screw 504 is rotatably mounted inside the outer slide groove 502. The screw 504 is threadedly connected to the slider 5032, and one end of the screw 504 is fixedly connected to the output shaft of the drive motor 505. The drive motor 505 is fixedly mounted on the horizontal frame. On the upper part, distance measuring elements 506 are symmetrically arranged on both sides of the slider 5032. A limit block 5034 is fixedly installed on one end of the slider 5032 near the toothed plate 5031. The limit block 5034 is slidably installed in the limit groove 5035, which is opened inside the toothed plate 5031. Side springs 5036 are symmetrically installed on both sides of the limit block 5034. The ends of the two side springs 5036 are respectively fixedly connected to the inner walls of the two ends of the limit groove 5035. Side plates 5037 are symmetrically installed on both sides of the positioning block 5034. One side of the side plate 5037 is on the same plane as the side of the limiting block 5034 away from the slider 5032. A snap-fit ​​groove 5038 is opened at the end of the limiting block 5034 away from the slider 5032. Contacts 5033 are installed on both the upper and lower sides of the slider 5032. The two contacts 5033 are electrically connected. A positioning and fixing module 5039 is provided on the side of the limiting groove 5035 away from the slider 5032.

[0023] The distance measuring component 506 includes pressure plates 5061 symmetrically arranged on both sides of the slider 5032. The pressure plates 5061 are slidably connected to the outer slide groove 502. Pressure sensors 5063 are installed on the inner walls of both ends of the outer slide groove 502. The pressure plates 5061 and pressure sensors 5063 correspond one-to-one. A compression spring 5062 is arranged between the pressure plates 5061 and the pressure sensors 5063. Two distance measuring components 506 are symmetrically arranged on both sides of the slider 5032. The compression spring 5062 is compressed by the movement of the pressure plates 5061, and the elastic force of the compression spring 5062 is detected by the pressure sensors 5063. This allows the movement distance of the toothed plate 5031 to be detected, which facilitates the calculation of the movement distance and rotation angle of the movable target 301, and thus facilitates the detection of the target width and length. The positioning and fixing module 5039 includes a movable groove 50391 formed on the side of the limiting groove 5035 away from the slider 5032. A movable plate 50392 is slidably installed inside the movable groove 50391. A snap-fit ​​block 50393 is fixedly installed on the side of the movable plate 50392 near the limiting groove 5035. The snap-fit ​​block 50393 snaps into the snap-fit ​​groove 5038. A second spring 50394 is symmetrically installed on the other side of the movable plate 50392. One end of the second spring 50394 is fixedly connected to the inner wall of the end of the movable groove 50391. A second magnetic block 5039 is installed on the movable plate 50392. 5. A second electromagnet 50396 is fixedly installed on the inner wall of the end of the movable groove 50391 away from the limiting groove 5035. A first conductive strip 5064 and a second conductive strip 5065 are symmetrically installed on the upper and lower inner walls of the outer sliding groove 502. The two first conductive strips 5064 and the two second conductive strips 5065 are respectively arranged on the upper and lower sides of the two pressure plates 5061. Before the driven slider 5032 moves, the locking block 50393 is first controlled to disengage from the locking groove 5038, so that the slider 5032 can move before the toothed plate 5031, so that the contact 5033 can make contact with the toothed plate 5031 before it moves. When the first conductive strip 5064 or the second conductive strip 5065 comes into contact, the first electromagnet 3096 is energized, enabling the movable target 301 to move or rotate. Simultaneously, when the toothed plate 5031 moves back, the slider 5032 moves back before the toothed plate 5031, causing the locking block 50393 to engage with the locking groove 5038. This allows the slider 5032 to move back to its original position, and the movable target 301 can also move back to its original position. When the contact point 5033 contacts the first conductive strip 5064, the first electromagnet 3096 attracts the first magnetic block 3095, causing the locking rod 3093 to move upwards and engage with the first locking groove 3098. 08. The movable target 301 and the sliding frame 305 are locked together and fixed, so that the toothed plate 5031 can move the movable target 301 away from the fixed target 201, which is convenient for detecting the width of narrow targets. When the contact 5033 contacts the second conductive strip 5065, the first electromagnet 3096 generates a repulsive force on the first magnetic block 3095, so that the locking rod 3093 is locked with the second locking groove 4, which fixes the sliding frame 305 and the horizontal frame 1, so that the toothed plate 5031 can rotate the movable target 301 away from the fixed target 201, which is convenient for detecting the length of long targets.

[0024] Working principle: In use, a target for width detection is selected. Both the fixed target device 201 and the movable target device 301 are composed of a laser rangefinder and a camera. The fixed target device 201 is turned on, so that the laser rangefinder emits a laser beam, which is emitted perpendicularly to the end position of the target, thus achieving laser targeting. The camera captures an image and transmits the image to the computer. The computer analyzes the image to ensure that the laser beam is emitted to the end of the target, completing the first positioning. The distance between the fixed target device 201 and the target is detected by the reflected light. The distance between the position where the laser beam is emitted from the fixed target device 201 and the position where the laser beam is emitted from the movable target device 301 is recorded as A. Then, the second electromagnet 50396 is energized, so that the second electromagnet 50396 attracts the second magnetic block 50395, causing the snap-fit ​​block 50393 to move toward the interior of the movable slot 50391, so that the snap-fit ​​block 50393 disengages from the snap-fit ​​slot 5038. When the target width is small, the drive motor 505 is controlled to receive a positive current, causing the screw 504 to rotate clockwise, which drives the slider 5032 to move away from the fixed target 201. First, due to the friction between the toothed plate 5031 and the inner wall of the outer slide groove 502, the limiting block 5034 is driven to move along the limiting groove 5035 away from the fixed target 201 until the end of the side plate 5037 contacts the inner wall of the end of the limiting groove 5035, and then the toothed plate 5031 is driven to move. When the end of the side plate 5037 contacts the inner wall of the end of the limiting groove 5035, the slider 5032 contacts the pressure plate 5061 on the side where the first conductive strip 5064 is provided. At the same time, the two contacts 5033 contact the two first conductive strips 5064 respectively. The two first conductive strips 5064 are connected in series with the first power supply and the first electromagnet 3096 through a wire. When the two first conductive strips 5064 are electrically connected, the first electromagnet 3096 can be supplied with a positive current, so that the first electromagnet 3096 attracts the first magnetic block 3095, causing the locking rod 3093 to move upward and lock into the first locking groove 308, thereby locking and fixing the sliding frame 305 and the movable target 301. When the toothed plate 5031 moves away from the fixed target 201, the toothed plate 5031 engages with the teeth 304 on the connecting plate 303. However, the sliding frame 305 and the connecting plate 303 cannot rotate at this time, thus driving the movable target 301 to move away from the fixed target 201. The laser rangefinder on the movable target 301 emits a laser, and the camera captures images during the movement. The images are analyzed by a computer until the laser emitted by the movable target 301 moves to the other end of the target. Then the movement of the movable target 301 stops, completing the second positioning. As the slider 5032 pushes the pressure plate 5061 to move, the compression spring 5062 is compressed, and the spring force of the compression spring 5062 is detected by the pressure sensor 5063, so the moving distance B of the toothed plate 5031 can be calculated. Only the target width A+B can be calculated. When it is necessary to detect a long target, the same operation as above is performed. One end of the target is positioned by fixing the target device 201, and the vertical distance between the fixing target device 201 and one end of the target is detected and recorded as C. Then, the second electromagnet 50396 is energized, so that the second electromagnet 50396 attracts the second magnetic block 50395, causing the locking block 50393 to move towards the inside of the movable slot 50391, so that the locking block 50393 disengages from the locking slot 5038. Then, the drive motor 505 is supplied with a reverse current, causing the slider 5032 to move toward the fixed target 201, which in turn causes the limiting block 5034 to move toward the fixed target 201 within the limiting groove 5035 until the side plate 5037 contacts the inner wall of the end of the limiting groove 5035. At this time, the slider 5032 contacts the pressure plate 5061 on the side where the second conductive strip 5065 is provided, and the contact point 5033 contacts the second conductive strip 5065. Since the two second conductive strips 5065 are connected in series with the second power supply and the first electromagnet 3096, when the two second conductive strips 5065 are connected in series, the first electromagnet 3096 is supplied with a reverse current, which causes the first electromagnet 3096 to generate a repulsive force on the first magnetic block 3095, causing the locking rod 3093 to move downward and engage with the second locking groove 4, thus locking and fixing the sliding frame 305 to the horizontal frame 1. Then, slider 5032 continues to move towards fixed target 201, which in turn drives toothed plate 5031 to move towards one side of fixed target 201. Since toothed plate 5031 engages with teeth 304 on connecting plate 303, it drives movable target 301 to rotate around axis 306 away from fixed target 201. Laser light is emitted from laser rangefinder on movable target 301, and images are captured by camera. These images are then analyzed by computer until the laser emitted by movable target 301 lands on the other end of the target. During the movement of toothed plate 5031, one side is pushed and pressure is applied. The movement of plate 5061 compresses the compression spring 5062, and the movement distance of toothed plate 5031 is detected by pressure sensor 5063. The rotation angle of movable target 301 is calculated by the movement of toothed plate 5031, denoted as D. The target length can then be calculated as AtanD + C, where F = kx according to Hooke's Law. The spring constant k of compression spring 5062 is known, and the elastic force F of compression spring 5062 is detected by pressure sensor 5063. Thus, the compression distance x of compression spring 5062 can be calculated, and subsequently, the movement distance of toothed plate 5031 can be calculated. After the test is completed, when the drive toothed plate 5031 moves back, the second electromagnet 50396 is first de-energized. When the slider 5032 moves back, the limit block 5034 moves back relative to the toothed plate 5031. When the locking groove 5038 on the limit block 5034 corresponds to the locking block 50393, the locking block 50393 moves back under the elastic force of the second spring 50394, so that the locking block 50393 is locked into the locking groove 5038, locking and fixing the toothed plate 5031 and the slider 5032, thereby driving the toothed plate 5031 to move back to its original position, and then driving the movable target 301 to move back or rotate back to its original position.
