Description

Technical Field

[0001] This invention relates to the field of workshop lighting and intelligent manufacturing technology, specifically to a multi-sensory fusion dynamic projection lighting system for intelligent manufacturing workshops. Background Technology

[0002] Workshop lighting is a core infrastructure for ensuring industrial production safety and improving operational efficiency. Its lighting effect directly affects the operational precision and personnel safety in processes such as precision assembly, equipment maintenance, and material handling. With the popularization of intelligent manufacturing technology, traditional workshop lighting devices have gradually upgraded from metal halide lamps and high-pressure sodium lamps to LED industrial and mining projectors, achieving certain breakthroughs in energy efficiency and service life. However, they are still difficult to adapt to the dynamic operation needs of modern workshops.

[0003] Current workshop lighting technology suffers from several significant shortcomings. First, the management model is rudimentary. Most lighting devices employ constant illumination or simple zone control, failing to dynamically adjust lighting parameters based on personnel movement, equipment operating status, and workload. This results in continuously high-brightness lighting in non-work areas, leading to substantial energy waste. Furthermore, in work areas, fixed lighting can create blind spots, affecting the accuracy of delicate operations such as welding and inspection, and increasing safety risks in high-risk tasks. Second, environmental adaptability is insufficient. Workshops such as heavy machinery assembly and automotive parts stamping typically experience harsh conditions including high dust levels, strong vibrations, and intense electromagnetic interference. Existing lighting devices often use single photosensitive sensors without specific protective structures, making them prone to sensor malfunctions and lamp misalignment. This results in frequent and costly maintenance and can disrupt production processes due to lighting interruptions. Third, the problem of limited functionality is prominent. Existing lighting devices only provide basic illumination and cannot visualize equipment operating status, operational instructions, or safety warnings. In critical stages such as mold switching and equipment maintenance, information exchange still relies on traditional methods such as physical signs and manual announcements, which suffers from drawbacks such as delayed information transmission and high error rates. Fourth, there is a lack of system coordination. Most existing lighting devices are independent operating equipment and have not established a linkage mechanism with production management systems such as the workshop manufacturing execution system (MES) and automated guided vehicles (AGVs). In emergency situations such as equipment failure or personnel violations, it is impossible to quickly switch to warning lighting mode, which makes it difficult to meet the integrated needs of intelligent production.

[0004] In recent years, some technologies have attempted to combine sensing technology with lighting devices to launch so-called "smart lighting" products. However, these technologies generally suffer from a lack of comprehensive sensing capabilities. Most only integrate light sensors, enabling simple dimming based on ambient light levels, but failing to comprehensively sense key parameters such as personnel location, equipment status, ambient dust concentration, and vibration frequency. Furthermore, these technologies are largely focused on lightweight scenarios such as offices and homes, and their sensor accuracy, protection levels, and algorithm logic have not been optimized for the complex conditions of industrial workshops, resulting in significantly reduced stability and reliability in high-dust and high-vibration environments.

[0005] The transformation of workshop production models towards flexibility and intelligence places higher demands on the scene adaptability, functional integration, and system coordination of lighting devices. Traditional lighting devices and existing basic intelligent lighting technologies can no longer meet the precise lighting needs of dynamic work scenarios, nor can they support the information interaction and coordinated control of intelligent manufacturing systems. Therefore, developing a projection lighting device for workshops that integrates multi-sensor technology, possesses dynamic control capabilities, and enables information visualization and system coordination has become a key measure to solve current workshop lighting pain points and promote the upgrading of intelligent manufacturing. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-sensory fusion dynamic projection lighting system for intelligent manufacturing workshops, which enables dynamic and precise control of illumination, enhances adaptability to harsh environments, and integrates information projection and system linkage functions to improve operational safety and production efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-sensor fusion-type dynamic projection lighting system for intelligent manufacturing workshops, comprising a multi-sensor module, a control module, a projection lighting module, and an automation management module; the multi-sensor module is uniformly deployed in key work areas of the workshop for real-time collection of workshop environmental parameters and work status data; the control module is electrically connected to the multi-sensor module, receives data transmitted by the multi-sensor module, and generates control commands through a built-in algorithm; the projection lighting module communicates bidirectionally with the control module, dynamically adjusting illumination-related parameters according to the control commands; the automation management module is connected to the control module to realize remote monitoring of the device, fault early warning, and linkage and collaboration with the existing production system in the workshop.

[0008] Furthermore, the multi-sensor module includes at least three of the following: a light sensor, an infrared sensor, a vibration sensor, and a dust concentration sensor. Each sensor is encapsulated in an industrial-grade protective shell. The shell surface is provided with a dustproof coating and a buffer vibration reduction structure. The sensors are connected in a distributed network manner and are evenly distributed in key areas such as the workshop welding area, maintenance area, and material transfer channel. They are used to collect light intensity distribution data, personnel and equipment location data, environmental vibration frequency data, and dust concentration data, respectively.

[0009] Furthermore, the control module is equipped with a multi-sensor data fusion algorithm and an intelligent lighting control algorithm. The multi-sensor data fusion algorithm is used to perform noise reduction, correlation, and integration analysis on heterogeneous data collected by multiple sensing modules to generate a unified scene judgment result. The intelligent lighting control algorithm is used to calculate the optimal lighting parameters based on the scene judgment result. The control module also has a fault self-diagnosis function, which can monitor the operating status of each module in real time. When abnormal conditions such as sensor failure or lamp group failure are detected, an early warning signal is automatically triggered and uploaded to the automated management module.

[0010] Furthermore, the projection lighting module consists of multiple sets of adjustable-focus LED projection lamps. Each set of LED projection lamps is equipped with a lens adjustment component driven by a stepper motor and an angle adjustment bracket. According to the control module's control instructions, the spatial position, light intensity, and projection angle of the lamp set can be adjusted independently or collaboratively. At the same time, the shape and size of the light spot are controlled by a DMD chip or an LCoS chip to achieve precise lighting coverage for different work areas.

[0011] Furthermore, the projection lighting module can project industrial-specific content such as equipment operation instructions, safety warning signs, and mold alignment marks. The display and switching of the projected content are automatically triggered by the control module according to the work scenario. During equipment maintenance, it projects equipment disassembly steps; during mold switching, it projects mold installation alignment marks; and when personnel enter high-risk areas, it projects safety warning lines and warning text.

[0012] Furthermore, the automated management module is equipped with a remote interactive interface, which integrates a device operation status display window, a manual adjustment panel for illumination parameters, and a fault information prompt module. It allows staff to log in to the interface through the workshop central control platform or mobile terminal to remotely view and manually control the device operation parameters, while also supporting the storage and export of historical operation data.

[0013] Furthermore, the automation management module adopts an industrial-grade communication protocol, which can be connected to management systems such as workshop MES and AGV, receive equipment operation signals and work task instructions issued by the production system, and upload device operation status data and environmental monitoring data to the production system at the same time, so as to achieve seamless linkage between the lighting device and the existing production system, automatically adjust the lighting mode when the equipment starts, and automatically turn on the path lighting when the AGV transfers materials.

[0014] Furthermore, the multi-sensing module adopts a dustproof and vibration-resistant protective structure design. The sensor shell is made of stainless steel and equipped with a sealing gasket. The interior is filled with buffer and vibration damping material. The sensor detection window is made of scratch-resistant and wear-resistant transparent glass. The overall protection level meets the requirements for use in workshop operating environments with high dust and strong vibration. It can operate stably under the conditions of daily average dust concentration of 0.8mg / m³ and vibration frequency of 5-15Hz.

[0015] Furthermore, the projection lighting module achieves adaptive brightness adjustment through PWM technology. The control module automatically adjusts the pulse duty cycle of the LED projection lamp based on the ambient light intensity data collected by the multi-sensor module. When the ambient light is sufficient, the brightness is reduced, and the lighting is automatically dimmed or turned off when personnel leave the work area, reducing ineffective energy consumption and reducing energy consumption by 25%-35% compared to traditional lighting devices.

[0016] Furthermore, the device is equipped with an emergency response mode. When the multi-sensor module detects equipment malfunction vibration signals, unauthorized personnel entry signals, or receives a fault alarm command issued by the workshop MES system, the projection lighting module immediately switches to a bright red warning spot. The angle adjustment component precisely focuses the spot on the risk area, and with the strobe effect, it achieves rapid warning to on-site personnel.

[0017] This invention provides a multi-sensory fusion dynamic projection lighting system for intelligent manufacturing workshops, which has the following beneficial effects: 1. This invention significantly enhances the adaptability of the device to harsh workshop environments. Addressing complex working conditions such as high dust levels in heavy machinery assembly workshops and strong vibrations in automotive parts stamping workshops, this invention employs a dustproof and vibration-resistant protective structure design for the multi-sensor modules. This effectively isolates dust intrusion and buffers high-frequency vibrations generated during equipment operation. This design prevents sensor malfunction due to environmental interference, ensuring long-term stable operation of the device. Experimental data shows that the device can achieve zero-failure operation under conditions of an average daily dust concentration of 0.8 mg / m³ and a vibration frequency of 5-15 Hz, reducing the failure rate by 100% compared to traditional lighting devices, while extending the device's lifespan by more than 30%, significantly reducing the maintenance frequency and replacement costs of workshop lighting equipment.

[0018] This invention achieves precise and comfortable lighting, improving the operator experience and accuracy. Traditional workshop lighting has a fixed light field, easily creating shadow blind spots in equipment and personnel work areas, affecting delicate operations such as precision assembly and equipment maintenance. This invention uses multi-sensor modules to collect real-time data on light distribution and personnel position, and a control module equipped with an optimization algorithm dynamically adjusts the position, light intensity, and projection angle of the projection lamps, ensuring uniform lighting throughout the work area. In an application case in the maintenance area of ​​a heavy machinery assembly workshop, the average light uniformity of the work area reached 92%, worker visual fatigue feedback decreased by 65%, effectively avoiding operational errors caused by insufficient lighting or glare, and providing stable visual assurance for high-precision operations.

[0019] This invention effectively improves workshop operation safety and production efficiency. Traditional lighting devices only provide basic illumination, and equipment operation instructions and safety warnings rely on physical signs and manual communication, resulting in information lag and inaccurate delivery. The projection lighting module of this invention can project industry-specific content such as equipment operation instructions and safety warning lines. It accurately projects alignment guidance during mold switching and switches to a bright red warning spot to focus on the risk area when equipment malfunctions. In its application in automotive parts stamping workshops, mold switching time has been reduced by 35%, the stamping operation error rate has decreased from 5% to 0.5%, and the accident rate has decreased by 80%. Visualized information delivery standardizes operating procedures and reduces production safety risks.

[0020] This invention offers significant energy savings and meets the demands of green industrial development. Traditional workshop lighting often employs constant brightness or simple zone control, resulting in substantial energy waste due to continuous high-brightness lighting in non-work areas. This invention, based on ambient light sensor feedback data, utilizes PWM technology to achieve adaptive brightness adjustment. It reduces brightness when ambient light is sufficient and automatically dims or turns off lighting when personnel leave the work area, minimizing ineffective energy consumption. Simultaneously, the device dynamically adjusts lighting parameters according to operational needs, avoiding energy losses caused by frequent manual adjustments. Practical application data shows that this device can reduce daily power consumption by 32% in heavy machinery assembly workshops and by 29% in automotive parts stamping workshops, saving considerable operating costs for the workshops.

[0021] The present invention realizes seamless linkage with the existing workshop management system, facilitating the intelligent upgrade of the workshop. Traditional lighting devices are independent operating equipment and cannot work in coordination with systems such as the workshop manufacturing execution system and automated guided vehicle. The automated management module of the present invention supports access to management systems such as workshop MES and AGV, and uses industrial-grade communication protocols to ensure stable data interaction. The device can receive the equipment operation signals of the production system, automatically project safety specifications when the equipment starts, and issue cleaning reminders when the dust concentration exceeds the standard, realizing the linkage response between the lighting system and the production system. This linkage function reduces the manual intervention link and improves the automation level of workshop management. In the application in the stamping workshop of automotive parts, the maintenance cost is reduced by 70% compared with traditional lighting, promoting the transformation of the workshop to an intelligent and flexible production mode.

Specific Embodiments

[0024] Here, the exemplary embodiments will be described in detail, and their examples are shown in the drawings. When the following description involves the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Usage Method: 1. Equipment Deployment and Networking: The light sensor, infrared sensor, vibration sensor, and dust concentration sensor from the multi-sensor module are evenly distributed in key operational areas such as the welding area, maintenance area, and material transfer channels in the workshop. Each sensor is connected using a distributed networking method. Simultaneously, the electrical connection status of the multi-sensor module, control module, projection lighting module, and automation management module is confirmed, and equipment initialization is completed.

[0027] System parameters are preset via the remote interactive interface of the automation management module, accessible through login to the system backend. Based on the needs of different workshop operating scenarios, preset parameters include light intensity thresholds, light spot shape parameters, dust concentration warning values, and emergency response trigger conditions. Simultaneously, system linkage parameters are configured to integrate the automation management module with existing production management systems such as the workshop's MES and AGV systems, ensuring smooth data exchange.

[0028] The device startup and data acquisition process begins with the main power supply being turned on, activating the multi-sensor modules. Each sensor collects real-time workshop environmental and operational data: the light sensor collects data on the distribution of light intensity in the area; the infrared sensor captures the location information of personnel and equipment; the vibration sensor monitors the environmental vibration frequency; and the dust concentration sensor records dust content data. All collected data is transmitted to the control module in real time.

[0029] The data processing and command generation control module uses a built-in multi-sensor data fusion algorithm to perform noise reduction, correlation, and integration analysis on the received heterogeneous data, generating a unified scene judgment result. Then, through an intelligent lighting control algorithm, it calculates the optimal lighting parameters for the current scene, generates corresponding control commands, and transmits them to the projection lighting module.

[0030] After receiving control commands, the projection lighting module dynamically adjusts the position, light intensity, and projection angle of the LED projector lamp by driving the lens adjustment assembly and angle adjustment bracket via a stepper motor. Simultaneously, it adjusts the light spot shape as needed using a DMD chip or LCoS chip. During equipment maintenance, it projects disassembly instructions, and during mold switching, it projects alignment markers, achieving precise lighting and visualized information transmission.

[0031] Remote monitoring and manual intervention are both possible. Personnel can view the device's operational status and environmental monitoring data in real time through the remote interactive interface of the automated management module. When operational parameters need adjustment, the illumination parameters can be manually modified directly on the interface. The command is then sent to the projection lighting module via the control module to update the parameters.

[0032] Emergency Response and Fault Handling: When the multi-sensor module detects equipment vibration signals, unauthorized personnel entry signals, or receives a fault alarm command from the MES system, the device automatically switches to emergency response mode. The projection lighting module immediately switches to a bright red warning spot and precisely focuses on the risk area. If the control module diagnoses abnormalities such as sensor malfunction or lighting failure, it will automatically trigger an early warning signal and upload it to the automation management module, allowing staff to promptly troubleshoot and handle the fault.

[0033] After the device shutdown and data storage operations are completed, a shutdown command is sent via the remote interface. The projection lighting module stops working, and the multi-sensor module terminates data acquisition. The automated management module automatically stores the operational data for this operation, including lighting parameters, environmental data, and fault records, for easy retrieval and review later.

[0034] Example: Example 1: Application in the welding area of ​​a heavy machinery assembly workshop This embodiment is applied to the welding area of ​​a heavy machinery assembly workshop. During the operation in this area, a large amount of dust is generated, and there is also continuous vibration caused by the operation of the welding equipment. Operators need to move around the large workpiece to perform welding operations, which requires high uniformity and tracking of the light.

[0035] During installation, the light sensor, infrared sensor, vibration sensor, and dust concentration sensor in the multi-sensor module are distributed in a distributed manner. All sensors are encapsulated in industrial-grade protective housings, and the dustproof coating and shock-absorbing structure on the housing surface effectively resist the effects of dust and vibration in the welding area. The light sensor is deployed around the welding station to collect light intensity data in different areas during the welding process; the infrared sensor is deployed around the workpiece to capture the movement trajectory of the operator; the vibration sensor and dust concentration sensor are directly installed near the welding equipment to monitor the equipment's operating status and the ambient dust content in real time. After the multi-sensor module, control module, projection lighting module, and automation management module are electrically connected, the light intensity threshold, dust concentration warning value, and emergency response trigger conditions for the welding operation are preset through the remote interactive interface of the automation management module. Simultaneously, the automation management module is integrated into the workshop MES system.

[0036] After the device is started, the multi-sensor module transmits the collected environmental and operational data to the control module in real time. The control module uses a multi-sensor data fusion algorithm to perform noise reduction, correlation, and integrated analysis on the heterogeneous data. When it detects the movement of the operator, it immediately generates a control command and sends it to the projection lighting module. The projection lighting module's multiple adjustable-focus LED projectors are driven by stepper motors to adjust the lens adjustment components and angle adjustment brackets, dynamically adjusting the position and projection angle of the lamp groups to ensure that the welding area is always uniformly illuminated. At the same time, the welding operation specifications are projected onto the workpiece surface through the DMD chip. When the vibration sensor detects abnormal operation of the welding equipment, or the dust concentration sensor detects excessive dust concentration, the control module triggers an emergency response mode. The projection lighting module immediately switches to a bright red warning spot, focusing on the abnormal area. Simultaneously, the automation management module uploads a warning message to the MES system. The operator can view the device's operating status in real time through a remote interactive interface and manually adjust the lighting parameters when necessary. After the operation is completed, a shutdown command is sent through the remote interactive interface. The automation management module automatically stores the operation data for this operation for easy retrieval and analysis later.

[0037] Example 2: Application in the maintenance area of ​​a heavy machinery assembly workshop This embodiment is applied to the maintenance area of ​​a heavy machinery assembly workshop. This area requires the disassembly and maintenance of large equipment. The work position is not fixed and the equipment disassembly guide needs to be checked frequently. Traditional fixed lighting cannot meet the dynamic work requirements.

[0038] During the equipment deployment phase, sensors from multiple sensing modules are evenly distributed around the equipment and in the maintenance passageways according to the spatial layout of the maintenance area. Light sensors are used to collect ambient light intensity data for the maintenance area, infrared sensors are used to locate maintenance personnel and the parts to be maintained, and vibration sensors are used to monitor equipment vibration during maintenance to prevent sensor malfunction due to vibration. After sensor deployment is complete, each module is connected, and the lighting parameters for maintenance operations are preset through the automation management module. Equipment disassembly guidance diagrams are entered into the system, and linkage parameters with the AGV system are configured. When the AGV transports maintenance tools to the maintenance area, lighting adjustments are automatically triggered.

[0039] During operation, the multi-sensor module collects data in real time and transmits it to the control module. When the infrared sensor detects that maintenance personnel have entered a certain area and begun operation, the control module calculates the optimal lighting parameters through an intelligent lighting control algorithm, driving the projection lighting module to adjust the brightness and angle of the LED projector, providing precise lighting for the maintenance operation. Simultaneously, the projection lighting module automatically projects corresponding equipment disassembly guidelines according to the maintenance steps; the guide content can be switched as the maintenance progresses. When maintenance personnel move to another area of ​​the equipment, the infrared sensor detects the change in position, and the projection lighting module synchronously adjusts the lighting and projection content, achieving the effect of "light follows the personnel, and the light follows the guide." If the control module detects an abnormality in sensor data through its fault self-diagnosis function, it will immediately issue an alert through the automation management module. Personnel can view the fault location and handle it promptly through a remote interactive interface. After the maintenance work is completed, the device power is turned off, and the automation management module stores data such as the lighting parameters and operation time of this maintenance, providing a reference for subsequent similar maintenance operations.

[0040] Example 3: Application of Die Changing Station in Automotive Parts Stamping Shop This embodiment is applied to the die changing station in the automotive parts stamping workshop. This station requires frequent switching of stamping dies of different specifications. Traditional lighting requires manual adjustment of the angle, and die alignment depends on manual visual judgment, which is inefficient and prone to errors.

[0041] During equipment installation, sensors from the multi-sensor module are deployed around the stamping equipment and in the die-changing area. Infrared sensors are used to identify the die type and location, light sensors are used to collect light intensity data in the die-changing area, and vibration sensors are used to monitor the operating status of the stamping equipment. All sensors are connected via a distributed network to ensure stable data transmission. After module connection is complete, alignment markings and installation instructions for different dies are entered through the remote interactive interface of the automation management module. Lighting parameters for die changing are preset, and the automation management module is linked to the stamping equipment's control system.

[0042] After the device starts up, when the stamping equipment sends a mold change signal, the multi-sensor module immediately collects relevant data and transmits it to the control module. The control module generates adjustment commands to drive the projection lighting module to adjust the angle and brightness of the LED projector, providing uniform and sufficient illumination for the mold change area. Simultaneously, the projection lighting module uses a DMD chip to precisely project the alignment lines of the corresponding mold onto the worktable of the stamping equipment, assisting workers in quickly aligning the mold. During mold installation, infrared sensors monitor the mold's installation position in real time. If an alignment deviation is detected, the control module immediately triggers the projection lighting module to project a warning sign, reminding workers to adjust. After mold change is completed, the projection lighting module automatically switches to the conventional lighting mode for stamping operations and projects the safety specifications for stamping operations. During operation, workers can monitor the device's operating status in real time through a remote interactive interface. If insufficient lighting or unclear projection occurs, relevant parameters can be manually adjusted.

[0043] Example 4: Application of material transfer channels in automotive parts stamping workshops This embodiment is applied to the material transfer channel in the automotive parts stamping workshop. This channel is the main travel path of AGVs, and workers also travel back and forth. The lighting needs to be dynamically adjusted according to the position of the AGVs and the passage of personnel to ensure the safety of the transfer.

[0044] During equipment deployment, infrared sensors from the multi-sensor module are evenly distributed along both sides of the material transfer channel to capture the position information of AGVs and personnel. Light sensors are placed above the channel to collect ambient light intensity. Vibration sensors are installed near the AGV's stopping point to monitor its start / stop status. After sensor deployment, the modules are connected, and lighting control logic is preset through the automation management module. When an AGV enters a section of the channel, the lighting in that area automatically brightens; when there are no personnel or AGVs in the channel, the lighting automatically dims and enters energy-saving mode. Simultaneously, linkage parameters with the AGV system are configured to achieve coordinated operation between lighting and AGV operation.

[0045] During operation, the multi-sensor module collects real-time data on the positions of personnel and AGVs within the passageway and transmits it to the control module. When the infrared sensor detects an AGV entering the passageway, the control module immediately generates a command to drive the projection lighting module to adjust the brightness of the LED projection lights in the AGV's travel area to a preset value, while simultaneously projecting a safety warning line for the AGV to alert personnel in the passageway to avoid it. When the AGV stops at a designated location to load or unload materials, the projection lighting module adjusts the illumination angle to provide precise lighting for the loading and unloading operations. If the infrared sensor detects personnel entering the passageway while the AGV is in motion, the control module immediately triggers an emergency response mode. The projection lighting module projects a red warning light spot, and the automation management module sends a warning signal to the AGV system, reminding the AGV to slow down and avoid the area. When there are no personnel or AGVs moving within the passageway, the control module adjusts the lighting brightness to an energy-saving mode using PWM technology based on data from the light sensor, reducing unnecessary energy consumption. Personnel can view the lighting status and AGV operation in the passageway through a remote interactive interface and manually intervene in the lighting parameters when necessary.

[0046] Example 5: Application in a Precision Electronic Component Assembly Shop This embodiment is applied to a precision electronic component assembly workshop, which has extremely high requirements for lighting accuracy, and needs to avoid glare and shadows. At the same time, it is necessary to project operation guidelines for component assembly to ensure assembly accuracy.

[0047] During installation, the vision and illumination sensors of the multi-sensor module are deployed above the assembly workbench. The vision sensors are used to identify components on the workbench and the operator's movements, while the illumination sensors collect data on the light intensity and uniformity of the workbench. Infrared sensors are used to locate the operator's hand position. All sensors are high-precision industrial-grade products to ensure accurate data acquisition. After deployment, the modules are connected, and the illumination parameters for the assembly operation are preset through the automation management module. Different component assemblies correspond to different illumination intensities and light spot shapes. Simultaneously, assembly operation instructions and safety specifications for various components are entered.

[0048] After the device is started, the multi-sensor module transmits the collected data to the control module. The control module analyzes the work scene using a multi-sensor data fusion algorithm. When it detects that a worker has begun assembling a component, it drives the projection lighting module to adjust the light spot shape via the DMD chip to match the size of the worktable. Simultaneously, it precisely controls the light intensity using PWM technology to avoid glare and shadows. The projection lighting module simultaneously projects the assembly steps for that component, with the instructions automatically changing as the assembly progresses. During assembly, the vision sensor monitors the worker's actions in real time. If any violation is detected, the control module triggers the projection lighting module to project a warning sign, reminding the worker to correct the error. Workers can access the assembly parameters for different components via a remote interface, compare the current lighting conditions, and manually adjust to the optimal mode. After the assembly operation is completed, the automation management module stores the lighting data and operation records for this operation, providing data support for subsequent process optimization.

[0049] Example 6: Emergency Repair Application for Workshop Equipment Failure This embodiment is applied to emergency repair scenarios for equipment failures in various workshops. When equipment in the workshop suddenly fails, it can quickly provide precise lighting and troubleshooting guidance for the repair area, shortening the repair time.

[0050] During routine deployment, the sensors of the multi-sensing module have been distributed throughout the workshop. The automated management module has pre-entered fault diagnosis guidelines and maintenance operation specifications for all equipment in the workshop and set emergency response trigger conditions. When the MES system sends a fault signal, the emergency lighting mode is automatically triggered.

[0051] When a piece of equipment in the workshop suddenly malfunctions, the MES system transmits the fault signal to the automation management module, which immediately initiates the emergency response procedure. The infrared sensors in the multi-sensor module quickly locate the faulty equipment, the light sensor collects ambient light data of the faulty area, and the vibration sensor monitors the vibration state of the faulty equipment. All data is transmitted to the control module in real time. The control module generates emergency lighting control commands, driving the projection lighting module to focus multiple LED projectors onto the faulty equipment, adjusting the light intensity and angle to provide maintenance personnel with comprehensive illumination. Simultaneously, the projection lighting module projects fault diagnosis guidance and maintenance procedures for the equipment. The guidance content can be manually or automatically switched according to the maintenance personnel's progress. During maintenance, if the control module detects abnormal dust concentration or vibration in the faulty area, it will promptly project warning information through the projection lighting module to remind maintenance personnel to pay attention to safety. After maintenance is completed, personnel turn off the emergency lighting mode through a remote interactive interface, and the device returns to normal operation. The automation management module automatically stores the lighting parameters and work records for this fault maintenance.
