Laser alignment and signal lamp interlocking device for monorail turnover beam

Abstract

This invention relates to a laser alignment and signal control device adapted to a monorail tilting beam, comprising a laser precision alignment self-diagnostic component and a fail-safe signal control component, deployed on a fixed beam and a tilting beam. The laser transmitter of the laser precision alignment self-diagnostic component emits a laser beam, which is split by a semi-transparent mirror, focused into a narrow beam by a laser collimator, and then directed towards a target substrate. If the laser hits the high-reflectivity center area, it returns and is received by the main receiver, triggering the energization of the waterproof electromagnet of the fail-safe signal control component. The second filter remains in place, and the LED light source emits green light. Otherwise, the waterproof electromagnet is de-energized, the second filter moves down to the front of the LED light source, and the LED light source emits red light. The systematic synergy of the two components in this invention fundamentally solves the inherent problems of accuracy drift, lack of self-diagnostic mechanism, and weak environmental interference resistance in traditional laser alignment systems, significantly improving the traffic safety and operational efficiency of monorail transit.

Description

Technical Field

[0001] This invention relates to the field of monorail transit engineering technology, specifically to a laser alignment and signal light control device adapted to a monorail tilting beam. Background Technology

[0002] With its strong climbing ability, small footprint, and excellent environmental adaptability, monorail transit has become the core choice for urban hub transfers and mountain transportation connections. As a key component for monorail lines to achieve branch switching and emergency connection, the docking accuracy and status control of the tilting beam directly determine the train's safety, structural durability, and operational efficiency.

[0003] Currently, in the docking application of monorail tilting beams, traditional laser alignment and signal light control devices face many technical bottlenecks, which severely restrict docking accuracy and operational safety. Traditional laser alignment systems rely on static optical path design and lack active self-diagnosis mechanisms. Potential issues such as laser emitter attenuation, optical path contamination, and wear on reflective targets cannot be detected in advance. They are also susceptible to interference from strong ambient light, track vibration, and temperature drift, leading to errors in alignment detection accuracy and failing to meet high-precision docking requirements. Furthermore, signal light control systems often employ purely electronic control logic, lacking mechanical redundancy. When power outages or electronic component failures occur, risks such as persistent green lights and erroneous signal displays can arise, violating the core principle of fault-oriented safety. Additionally, some existing dynamic alignment devices rely solely on light intensity feedback for passive response, lacking active control mechanisms. In scenarios involving rapid docking of flip-beams, their response is sluggish, and their adaptability is insufficient. For example, light path refraction in humid environments can cause detection distortion, and mechanical component jamming under vibration conditions can cause signal delays. More critically, existing devices lack targeted protection and cleaning designs. Optical components are easily contaminated by dust, rainwater, and oil, clogging optical paths and requiring frequent shutdowns for cleaning and maintenance. This not only reduces operational efficiency but may also lead to safety risks such as metal component collisions and train misoperation due to incomplete cleaning. While there are a few existing signal lights with mechanical interlocks, their complex structure, high risk of jamming of moving parts, and lack of deep integration with the laser alignment system make it impossible to achieve integrated control of alignment status, signal display, and fault warning, thus failing to meet the dynamic docking and safe operation requirements of monorail tilting beams.

[0004] Therefore, it is necessary to propose new measures to overcome the above-mentioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide a laser alignment and signal light control device adapted to a single-rail flipping beam, so as to solve the problems of existing technologies that cannot meet the requirements of high-precision docking, poor reliability and environmental adaptability.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A laser alignment and signal light control device adapted to a single-rail tilting beam is provided. The device includes a laser precision alignment self-diagnosis component and a fail-safe signal control component.

[0008] The laser precision alignment self-diagnostic component includes a laser emitter, a semi-transparent and semi-reflective mirror, a laser collimator, and a main receiver, which are deployed in a first groove on the end face of the fixed beam near the flip beam; it also includes a target substrate with a high-reflectivity central area, which is deployed in a second groove on the end face of the flip beam that is longitudinally opposite to the first groove;

[0009] The fail-safe signal control assembly is located on the transverse side of the top of the fixed beam, and includes a red second filter and a green LED light source; the second filter is located above and in front of the LED light source, and a waterproof electromagnet is installed on top of it;

[0010] The laser emitter emits a laser beam, which is split by the semi-transparent mirror and focused into a narrow beam by the laser collimator before being directed toward the target substrate. If the laser hits the highly reflective central region, the reflected laser returns and is received by the main receiver, which then energizes the waterproof electromagnet, keeps the second filter in its original position, and the LED light source emits green light. If the laser does not hit the highly reflective central region, the main receiver does not receive the reflected laser, which then de-energizes the waterproof electromagnet, moves the second filter to the front of the LED light source, and the LED light source emits red light.

[0011] Furthermore, the laser precision alignment self-diagnostic component also includes a diagnostic reflector, a calibration receiver, and a first filter, which are deployed within the first groove;

[0012] The first filter is fixed on a fixed plate, and an electric cylinder is provided on the outer side of the fixed plate. The fixed plate moves laterally under the drive rod of the electric cylinder, so that the first filter can cut into or out of the laser light path.

[0013] When the first filter enters the laser path, the laser emitter emits laser light, which is split by the semi-transparent mirror and focused into a narrow beam by the laser collimator. The reflected laser light is then reflected back and directed towards the diagnostic mirror, and after being reflected again by the diagnostic mirror, it is received by the calibration receiver, completing a self-test. This activates the waterproof electromagnet, keeps the second filter in its original position, and the LED light source emits green light. If the calibration receiver does not receive the reflected laser light, it de-energizes the waterproof electromagnet, moves the second filter down to the front of the LED light source, and the LED light source emits red light.

[0014] Furthermore, the fixing plate has a light-transmitting hole located on the lateral side of the first filter;

[0015] After completing the self-test, the fixing plate moves laterally under the drive rod of the electric cylinder, causing the first filter to cut out the laser light path. The laser passes through the light-transmitting hole, switching from the self-test mode to the monitoring mode.

[0016] Furthermore, the laser precision alignment self-diagnostic component also includes a probe housing;

[0017] The laser emitter, the semi-transparent mirror, and the laser collimator are arranged longitudinally from the inside to the outside and fixed to the inner wall of the probe housing. The semi-transparent mirror is arranged at a 45° angle.

[0018] The main receiver is located above the semi-transparent mirror and is fixed to the inner wall of the probe housing.

[0019] Furthermore, the diagnostic reflector is located above and outside the laser collimator and is fixed to the inner wall of the probe housing, and the diagnostic reflector is arranged at a 45° angle.

[0020] The verification receiver is located below the diagnostic reflector and is fixed to the inner wall of the probe housing.

[0021] Furthermore, a transverse light valve plate is provided on the inner wall of the probe housing. The light valve plate is located outside the laser collimator, the diagnostic reflector, and the calibration receiver, and is located on the transverse side inside the probe housing.

[0022] The end face of the light valve plate is provided with a transverse sliding groove, and the first filter is inserted into the sliding groove and can move laterally.

[0023] Furthermore, the electric cylinder is located outside the probe housing, the fixed end of the electric cylinder is fixed to the outer wall of the probe housing, the output end of the electric cylinder is fixed to the bottom plate of the L-shaped plate, and the vertical plate of the L-shaped plate is inserted into the through groove provided on the probe housing and fixed to the end of the fixed plate.

[0024] Furthermore, a sapphire window is provided at the outer end of the probe housing.

[0025] Furthermore, the fail-safe signal control assembly also includes a metal plate, a support column, and a signal light housing. The metal plate is fixed to the top surface of the fixed beam, the support column is fixed to the top surface of the metal plate, and the signal light housing is fixed to the side surface of the support column.

[0026] The second filter and the LED light source are located inside the signal light housing;

[0027] The second filter is provided with a sealing sleeve that is open at the top and bottom, and a focusing lens is provided on the outside of the LED light source.

[0028] Furthermore, vertical slides are provided on both sides inside the sealing sleeve, and nylon rollers are provided on both end faces of the second filter, the nylon rollers being inserted into the slides;

[0029] The top of the second filter is provided with a sheet metal, and the waterproof electromagnet is fixed to the top inside the signal light housing;

[0030] The second filter also has small vertical tension springs on both sides of its bottom.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] This invention provides a laser alignment and signal control device adapted to monorail tilting beams, upgrading the precise detection and safe control of monorail tilting beam docking from a decentralized technology to an integrated solution. Through the systematic collaboration of a laser precision alignment self-diagnostic component and a fail-safe signal control component, it achieves spatiotemporal unification of precise detection and safe control. The laser precision alignment self-diagnostic component relies on a pure mechanical and photoelectric closed loop composed of dual-beam splitting, active switching of mechanical shutters, and dual-receiver verification, fundamentally solving the inherent problems of precision drift, lack of self-diagnostic mechanism, and weak environmental anti-interference capability of traditional laser alignment systems. It significantly improves the traffic safety and operational efficiency of monorail transit, meeting the stringent requirements of modern monorail transit for high precision, high reliability, and high environmental adaptability.

Detailed Implementation

[0051] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0052] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "longitudinal", "lateral", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0053] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection," "setting," etc., should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0054] Furthermore, in the description of this invention, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Of course, such terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in a sequence other than those illustrated or described herein.

[0055] In a specific implementation, Figure 1 The length direction of the central track is defined as longitudinal, and the direction perpendicular to it is defined as transverse. The two ends of the longitudinal direction are front and back, and the two ends of the transverse direction are left and right. In addition, for structures such as grooves, the side closer to the bottom of the groove is defined as the inner side, and the side closer to the opening of the groove is defined as the outer side.

[0056] The tilting track beam structure is suitable for straddle-type monorail transit systems, serving as a single track turnout. The tilting track beam enables train steering or line switching. For example... Figure 1 The tilting track beam structure includes a tilting beam 200 and fixed beams 100 on both longitudinal sides. The top surface of the tilting beam 200 has a straight rail, and the bottom surface has a curved rail. A rotating shaft passes longitudinally through and is fixed inside the tilting beam 200. By rotating the rotating shaft, the tilting beam 200 can be tilted axially. When the train needs to turn or switch tracks, the tilting beam 200 tilts 180°, flipping the curved rail on the bottom surface to the top surface. The other end of the curved rail then connects to another monorail, thus realizing the train's turning or track switching.

[0057] To ensure train operation safety, it is essential to ensure that the flipping beam 200 is precisely aligned with the fixed beam 100 after flipping. To this end, this invention provides a laser alignment and signal light control device adapted to monorail flipping beams, upgrading the precise detection and safety control of monorail flipping beam docking from a decentralized technology to an integrated solution. It has a monitoring mode and a self-inspection mode, effectively improving the traffic safety and operational efficiency of monorail transit.

[0058] like Figure 1-3 In this embodiment, the device includes a laser precision alignment self-diagnostic component 300 and a fail-safe signal control component 400. The laser precision alignment self-diagnostic component 300 performs alignment monitoring and device self-test, while the fail-safe signal control component 400 provides indicator lights to indicate the alignment and self-test results.

[0059] like Figure 4-6The laser precision alignment self-diagnostic component 300 includes a laser emitter 303, a semi-transparent mirror 304, a laser collimator 305, and a main receiver 306, deployed in a first groove on the end face of the fixed beam 100 near the flip beam 200. The laser precision alignment self-diagnostic component 300 also includes a target substrate 317 with a centrally located high-reflectivity central area 318, deployed in a second groove on the end face of the flip beam 200 longitudinally opposite to the first groove. The periphery of the high-reflectivity central area 318 is a low-reflectivity peripheral area. This part of the structure is used for alignment monitoring during the flipping of the flip beam 200. The laser emitter 303 provides a stable red laser source, the semi-transparent mirror 304 splits the laser beam, the laser collimator 305 focuses the divergent laser into a narrow beam, and the main receiver 306 receives the reflected laser signal. The distinct difference in reflectivity between the high-reflectivity central area 318 and the low-reflectivity peripheral area of ​​the target substrate 317 allows the main receiver 306 to quickly distinguish the alignment status.

[0060] The first and second grooves provide precise installation space for the probe housing 302 and target substrate 317 of the laser precision alignment self-diagnostic component 300, respectively. The dimensions of the first and second grooves are precisely matched with the component contours, which not only avoids interference with other structures such as the flip beam 200 and the fixed beam 100 during installation, but also ensures the coaxiality of the laser emitting end and the reflective target during the docking process, thus providing a structural basis for high-precision alignment detection.

[0061] The laser precision alignment self-diagnostic component 300 also includes a diagnostic reflector 307, a calibration receiver 308, and a first filter 314, all disposed within a first groove. The first filter 314 is fixed to a mounting plate 311. An electric cylinder 313 is positioned laterally on the outer side of the mounting plate 311. The mounting plate 311 moves laterally under the drive of the electric cylinder 313, allowing the first filter 314 to enter or exit the laser path. This part of the structure is used for the self-test of the laser precision alignment self-diagnostic component 300. The diagnostic reflector 307 vertically reflects the laser from the self-test optical path to the calibration receiver 308, which receives the reflected laser signal from the self-test optical path.

[0062] like Figure 7-12 A fail-safe signal control assembly 400 is disposed on the transverse side of the top of the fixed beam 100, including a red second filter 406 and a green LED light source 414. The second filter 406 is located above and in front of the LED light source 414, and a waterproof electromagnet 409 is mounted on top of it. The second filter 406 completely covers the light-emitting surface of the LED light source 414, converting green light into pure red light. The waterproof electromagnet 409 generates a strong attraction to the second filter 406 when energized, and releases the second filter 406 when de-energized, allowing it to slide down and cover the LED light source 414.

[0063] The device in this embodiment has two working states: self-test mode and monitoring mode. The self-test mode completes the device self-test, and then it can be switched to the monitoring mode for alignment monitoring.

[0064] In self-test mode, the first filter 314 enters the laser path, the laser emitter 303 emits a laser beam, which is split by the semi-transparent mirror 304 and focused into a thin beam by the laser collimator 305. The beam is then reflected by the first filter 314, and the reflected laser returns and is directed towards the diagnostic mirror 307. After being reflected again by the diagnostic mirror 307, it is received by the calibration receiver 308, completing the self-test. The waterproof electromagnet 409 is then energized, the second filter 406 remains in its original position, and the LED light source 414 emits green light. If the calibration receiver 308 does not receive the reflected laser, the waterproof electromagnet 409 is de-energized, the second filter 406 moves down to the front of the LED light source 414, and the LED light source 414 emits red light.

[0065] The fixed plate 311 has a light-transmitting hole located on the lateral side of the first filter 314. After the device completes its self-test, the fixed plate 311 moves laterally under the drive rod of the electric cylinder 313, causing the first filter 314 to cut out the laser light path. The laser passes through the light-transmitting hole, and the device switches from the self-test mode to the monitoring mode.

[0066] In monitoring mode, the laser emitter 303 emits a laser beam, which is split by the semi-transparent mirror 304 and focused into a fine beam by the laser collimator 305 before being directed toward the target substrate 317. If the laser hits the high-reflectivity center area 318, the reflected laser returns and is received by the main receiver 306, which then energizes the waterproof electromagnet 409, keeps the second filter 406 in its original position, and the LED light source 414 emits green light. If the laser does not hit the high-reflectivity center area 318, the main receiver 306 does not receive the reflected laser, which then de-energizes the waterproof electromagnet 409, moves the second filter 406 to the front of the LED light source 414, and the LED light source 414 emits red light.

[0067] like Figure 4-5The laser precision alignment self-diagnostic component 300 also includes a probe housing 302. A laser emitter 303, a semi-transparent mirror 304, and a laser collimator 305 are arranged longitudinally from the inside out. The laser emitter 303 is fixed to the inner wall of the probe housing 302 by bolts. The semi-transparent mirror 304 is arranged at a 45° angle, and both the semi-transparent mirror 304 and the laser collimator 305 are fixed to the bottom of the inner wall of the probe housing 302 by bolts. The main receiver 306 is located above the semi-transparent mirror 304 and is fixed to the top of the inner wall of the probe housing 302 by bolts. Additionally, a diagnostic reflector 307 is located above and to the outside of the laser collimator 305 and is fixed to the top of the inner wall of the probe housing 302 by bolts. The diagnostic reflector 307 is arranged at a 45° angle and, after precise calibration, ensures that the laser from the self-test optical path is vertically reflected to the calibration receiver 308. The calibration receiver 308 is located below the diagnostic reflector 307 and is bolted to the bottom inner wall of the probe housing 302. This split-mounting bolt method ensures the precise installation of core optical components such as the semi-transparent mirror 304 and the laser collimator 305, thereby guaranteeing that the coaxiality error of the optical path transmission is controlled within the design range. Furthermore, the probe housing 302 forms a closed space, reducing interference from external dust and airflow on the optical components. Simultaneously, the removable bolted connection facilitates cleaning or replacement of components, thus improving the ease of equipment maintenance.

[0068] like Figure 6 The inner wall of the probe housing 302 is provided with a transverse optical valve plate 309. The optical valve plate 309 is located outside the laser collimator 305, the diagnostic mirror 307, and the calibration receiver 308, and is located on one transverse side inside the probe housing 302. The end face of the optical valve plate 309 is provided with a transverse sliding groove 310. The first filter 314 is inserted into the sliding groove 310 and can move laterally. The sliding groove 310 integrated in the optical valve plate 309 provides a guide track for the sliding of the first filter 314, and the inner wall of the sliding groove 310 is smoothed, thereby reducing the frictional resistance when the first filter 314 slides, ensuring smoothness during mode switching. At the same time, the optical valve plate 309 has a compact structural design, effectively utilizing the internal space of the probe housing 302.

[0069] The electric cylinder 313 is located outside the probe housing 302. Its fixed end is fixed to the outer wall of the probe housing 302, and its output end is fixed to the base plate of the L-shaped plate 312. The vertical plate of the L-shaped plate 312 is inserted into a through slot on the probe housing 302 and fixed to the end of the fixed plate 311. The electric cylinder 313 acts as a power source, driving the fixed plate 311 to slide along the slide groove 310 via the L-shaped plate 312. The electric cylinder 313 has a rapid response and precise stroke, enabling it to switch between monitoring and self-test modes within 3 seconds, adapting to scenarios requiring rapid docking of the flip beam 200. Furthermore, the secure connection between the first filter 314 and the fixed plate 311 ensures that the filter will not shift or loosen during sliding. Its highly reflective film efficiently reflects laser light, providing a stable optical path for the self-test mode.

[0070] A sapphire window 315 is also provided at the outer end of the probe housing 302, embedded in the end cap at the outer end of the probe housing 302. The sapphire window 315 has both high light transmittance and wear and corrosion resistance, allowing the laser to pass through smoothly while blocking dust and rainwater from corroding the inside of the probe, thereby extending the service life of the optical components. In addition, the distinct difference in reflectivity between the high-reflectivity central area 318 and the low-reflectivity peripheral area of ​​the target substrate 317 allows the main receiver 306 to quickly distinguish the alignment state, thereby improving the recognition of the detection signal. At the same time, the elastic sealing gasket 316 can buffer the impact force when the flip beam 200 is docked, preventing the target substrate 317 from being deformed due to collision and affecting the detection accuracy.

[0071] A silicone rubber elastic pad 301 is also provided on the bottom outer side of the probe housing 302, embedded in the bottom of the first groove. An elastic sealing pad 316 is provided on the back of the target substrate 317, embedded in the bottom of the second groove. The silicone rubber elastic pad 301 can effectively absorb the vibration and impact generated during the operation of the monorail, preventing the vibration from being transmitted to precision optical components such as the laser emitter 303, and preventing optical path deviation from affecting detection accuracy. At the same time, the elastic sealing pad 316 subsequently cooperates with the target substrate 317 to improve the sealing and protection effect at the component connection.

[0072] like Figure 7-9The fail-safe signal control assembly 400 also includes a metal plate 401, a support column 402, and a signal lamp housing 403. The metal plate 401 is fixed to the top surface of the fixed beam 100, the support column 402 is fixed to the top surface of the metal plate 401, and the signal lamp housing 403 is fixed to the side of the support column 402. A second filter 406 and an LED light source 414 are located inside the signal lamp housing 403. The height of the LED light source 414 is located in the middle region of the three regions from top to bottom on the front surface of the signal lamp housing 403. The emitting surface of the LED light source 414 faces the front of the signal lamp housing 403. A focusing lens 415 is located in front of the LED light source 414 and corresponds to the middle region. The second filter 406 is located above and in front of the LED light source 414 and is vertically movable. When the second filter 406 moves downward into position, it covers the emitting surface of the LED light source 414 in the middle region. A sealing sleeve 404 with open top and bottom is provided outside the second filter 406.

[0073] The metal plate 401 and the support column 402 form a stable mounting bracket, which can precisely fix the signal light housing 403 at a preset height on top of the fixed beam 100, ensuring that the train driver can clearly see the signal from 800 meters away. The signal light housing 403 can be made of 316L stainless steel with an IP65 protection rating, which can effectively resist harsh outdoor environments such as high and low temperatures, rain, snow, and dust. In addition, the hollow structure of the sealing sleeve 404 cooperates with the slide rail 405 to provide an independent sliding space for the second filter 406. At the same time, the sealing sleeve 404 can prevent dust from entering the slide rail 405, thereby avoiding affecting the sliding performance of the second filter 406.

[0074] like Figure 11-12 Vertical slide rails 405 are provided on both sides inside the sealing sleeve 404, and nylon rollers 407 are provided on both end faces of the second filter 406. The nylon rollers 407 are inserted into the slide rails 405. The nylon rollers 407 convert the sliding friction between the second filter 406 and the slide rails 405 into rolling friction, which greatly reduces the coefficient of friction and effectively prevents the second filter 406 from getting stuck during sliding, ensuring that the light color can be switched in a very short time in case of failure.

[0075] like Figure 12A metal sheet 408 is provided on the top of the second filter 406, and a waterproof electromagnet 409 is fixed to the top inside the signal light housing 403. When the waterproof electromagnet 409 is energized, it generates a strong attraction to the metal sheet 408, thereby fixing the second filter 406. The metal sheet 408 enhances the attraction between the second filter 406 and the waterproof electromagnet 409, thus ensuring that the second filter 406 can be stably fixed on the top during normal operation. The waterproof electromagnet 409 has an IP65 protection rating, can adapt to outdoor humid environments, avoids failure of the waterproof electromagnet 409 due to moisture, and improves the reliability of the fail-safe signal control assembly 400.

[0076] like Figure 10 The bottom sides of the second filter 406 are also provided with small vertical tension springs 411 to provide redundancy for downward sliding power. Specifically, the bottom of the second filter 406 is symmetrically connected to two first limiting seats 410. The bottom of each of the two first limiting seats 410 is connected to a corresponding small tension spring 411. The bottom of each of the two small tension springs 411 is connected to a second limiting seat 412. The bottom of each of the two second limiting seats 412 is connected to a connecting block 413. The rear side of the two connecting blocks 413 is fixed to the inner wall of the signal light housing 403. The symmetrically arranged small tension springs 411 can provide balanced downward sliding power for the second filter 406. Working in conjunction with the weight of the second filter 406, they can ensure that the second filter 406 can slide down quickly and smoothly after the waterproof electromagnet 409 loses power. The first limiting seat 410 and the second limiting seat 412 can precisely fix the upper and lower ends of the small tension spring 411, preventing the small tension spring 411 from falling off or shifting during extension and contraction, thereby extending the service life of the small tension spring 411. The dual-color design of the LED light source 414, together with the second filter 406, enables clear switching of red and green signals, and its low power consumption and long lifespan characteristics are suitable for long-term continuous operation. The focusing lens 415 can focus the LED light into a parallel beam, improving the visibility distance in strong light environments and ensuring that the driver can accurately identify the signal status even in complex weather conditions.

[0077] The device provided by this invention has the following operating process:

[0078] 1. After the system is powered on and initialized, the laser precision alignment self-diagnostic component 300 initiates the self-test process first:

[0079] First, the electric cylinder 313 on one side of the outer wall of the probe housing 302 receives the control signal and drives the fixing plate 311 to slide along the slide groove 310 inside the light valve plate 309 through the L-shaped plate 312, so that the first filter 314 on the inner side of the fixing plate 311 cuts into the laser light path.

[0080] At this time, the stable red laser emitted by the laser emitter 303 is split by the semi-transparent and semi-reflective mirror 304, penetrates the laser collimator 305 and is reflected by the high-reflectivity film of the first filter 314. The reflected laser is directed towards the diagnostic reflector 307, which is bolted to the top of the inner wall of the probe housing 302. After being vertically reflected by the diagnostic reflector 307, it is incident on the verification receiver 308 at the bottom of the inner wall of the probe housing 302. When the signal strength received by the verification receiver 308 meets the standard, it is determined that the optical components are fault-free.

[0081] 2. After the self-test passes, the electric cylinder 313 begins to reverse its movement and moves the first filter 314 out of the optical path. At this time, the laser precisely aligns with the self-diagnostic component 300 and switches to monitoring mode.

[0082] The laser emitted by the laser emitter 303 is split by the semi-transparent mirror 304 and focused into a fine beam by the laser collimator 305. It then passes through the sapphire window 315 embedded in the right end cap of the probe housing 302 and is directed toward the target substrate 317 on the flip beam 200, which is connected to the elastic sealing gasket 316. When the laser hits the highly reflective central area 318 of the target substrate 317, the reflected laser returns along the original path and is reflected by the semi-transparent mirror 304 to the main receiver 306 at the top of the inner wall of the probe housing 302.

[0083] After receiving a strong signal, the main receiver 306 sends a command to the fail-safe signal control assembly 400, which energizes the waterproof electromagnet 409 embedded in the top of the inner wall of the signal light housing 403. This generates a strong attraction to attract the metal sheet 408 on the top of the second filter 406. The second filter 406 is then attracted and fixed to the top by the slide rails 405 on the inner wall of the sealing sleeve 404 via the nylon rollers 407 on both sides. At this time, the green light source above the LED light source 414 on one side of the inner wall of the signal light housing 403 is lit, and the light is focused into a parallel beam by the focusing lens 415 between the inner walls and emitted to provide a passage signal for the train.

[0084] When the laser misses the high-reflectivity center area 318 and the calibration receiver 308 fails to receive a self-test signal, the control unit cuts off the power to the waterproof electromagnet 409. Simultaneously, the second filter 406, under the combined action of the tension of the small tension springs 411 symmetrically arranged at the bottom and its own gravity, slides rapidly down the slide rail 405 and completely covers the emitting surface of the green LED light source 414, converting the green light into pure red light. At the same time, the red light source below the LED light source 414 is illuminated to assist in lighting up, and a safety warning signal is emitted through the focusing lens 415. Throughout the process, the laser precisely aligns with the self-diagnostic component 300, which absorbs vibration through the silicone rubber elastic pad 301 and buffers impact through the elastic sealing pad 316. The fail-safe signal control component 400, with its 316L stainless steel shell and IP65 protection rating, resists harsh environments, achieving precise detection and safe control through the systematic collaboration of the two components.

[0085] The device provided by this invention has the following technical advantages:

[0086] 1. This invention achieves spatiotemporal unification of precise alignment detection and safe self-check control through the systematic collaboration of the laser precision alignment self-diagnosis component 300 and the fail-safe signal control component 400. The laser precision alignment self-diagnosis component 300 relies on a pure mechanical and photoelectric closed loop composed of dual-optical-path beam splitting, active switching of mechanical shutters, and dual-receiver verification, which fundamentally solves the inherent problems of precision drift, lack of self-diagnosis mechanism, and weak environmental anti-interference capability of traditional laser alignment systems.

[0087] 2. The fail-safe signal control component 400 of the present invention uses the functions of adsorption by a waterproof electromagnet 409, buffering by a small tension spring 411, and guidance by a nylon roller 407 to change the color of the signal light by moving up and down with the help of a second filter 406, so as to ensure that the signal light is always in the optimal safe state of a fail-safe red light.

[0088] 3. This invention employs a dual-mode optical path design for self-testing and monitoring. Real-time verification of optical component status is achieved through active switching via a mechanical shutter, significantly improving the anti-interference capability of alignment detection, fully preserving the accuracy of laser transmission, and greatly reducing environmental interference errors. Furthermore, the fail-safe signal control component 400's purely mechanical redundancy design ensures reliable triggering of the red light in case of power failure, and effectively prevents the second filter 406 from jamming via the nylon roller 407, completely avoiding the risk of false signal display.

[0089] 4. This invention improves equipment efficiency through functional integration and structural simplification. The laser component integrates four major functions: transmission, reception, self-diagnosis, and protection. The fail-safe signal control component achieves safe control through core components such as a waterproof electromagnet 409, a second filter 406, and a small tension spring 411, significantly reducing equipment complexity and failure rate. It achieves automatic logic for alignment detection, signal display, and fault warning, completely eliminating human intervention errors. The split-type sealed protection and anti-blocking design ensure long-term cleanliness of the optical channel. The core design, which is algorithm-free and requires no frequent calibration, gives the equipment a long lifespan and maintenance-free characteristics, perfectly adapting to the high-density operation requirements of single-rail tilting beams.

[0090] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
