Description

Technical Field

[0001] This invention relates to the field of building inspection and surveying technology, specifically to an adaptive illumination enhancement device for assisting building surveying instruments. Background Technology

[0002] Historical building conservation and inspection is a core component of cultural relic protection and architectural engineering inspection. Its accuracy directly determines the scientific validity and rationality of the restoration plan. Clear lighting conditions are fundamental for accurate inspections, including component material identification, crack width measurement, and surface damage observation. However, historical buildings generally suffer from severe lighting deficiencies. On one hand, traditional architectural structures are limited by features such as deep eaves, high windows, arches, and numerous internal partitions, resulting in extremely low utilization of natural light. On the other hand, the window panels and glass of buildings over a century old are weathered, mottled, and damaged over time, reducing light transmittance by 40%-60% compared to newer buildings. Furthermore, many historical buildings are located in protected cultural relic areas, making it impossible to arbitrarily add fixed lighting facilities, further exacerbating the lack of internal lighting.

[0003] To address the challenge of low-light detection, existing lighting solutions in the industry mainly fall into three categories: general-purpose handheld lighting devices, built-in lighting in surveying instruments, and industrial-specific lighting accessories. However, all of these solutions have significant technical drawbacks: general-purpose handheld LED lights and similar devices cannot be coaxially fixed with surveying instruments, resulting in a large deviation between the lighting direction and the detection direction. Furthermore, their brightness is mostly adjustable in fixed increments, making them unsuitable for the reflective properties of different materials. Built-in lighting in surveying instruments generally has fixed brightness and non-adjustable angles, leading to severe light attenuation in deep spaces and making it difficult to meet the needs of long-distance detection. While industrial-specific lighting accessories offer brightness adjustment, their proprietary interfaces only fit specific brands of equipment, resulting in poor versatility. Additionally, they lack angle locking mechanisms, making them prone to light deviation due to vibrations during the detection process.

[0004] In summary, existing technologies cannot simultaneously meet the three core requirements of building surveying and inspection for lighting equipment: high adaptability, precise adjustment, and lightweight and stable operation. Inspection work in low-light environments still suffers from low efficiency and poor accuracy. Therefore, an adaptive lighting enhancement device to assist building surveying instruments is proposed. Summary of the Invention

When faced with different inspection angles and illumination requirements, the brightness and angle can be flexibly adjusted to meet the inspection requirements in various special environments.

[0027] LED chip 5 is model CREEXML2-T6, rated voltage 3.2-3.7V, rated current 3A, color temperature 5000K neutral white light, color rendering index Ra=88, luminous efficacy 130-150 lumens / watt, and lifespan not less than 50,000 hours; aluminum substrate 6 is model MCPCB-2012, thickness 1.5-2mm, surface with thermally conductive coating, and thermally conductive adhesive with a thermal conductivity ≥3.0W / (m・K) is bonded between it and the LED chip, with a thermal conductivity of 2.0W. / (m・K); The heat dissipation fins are made of 6061-T6 aluminum alloy, with a total of 16 fins, each fin is 1mm thick, and the spacing between adjacent fins is 3mm. They are used with a 3010 type micro cooling fan (30×30×10mm, speed 5000rpm, air volume 0.8CFM) to achieve a heat dissipation power of ≥5W. The micro cooling fan is snapped and fixed to the outer shell of the LED light source module (1). The detachable transparent light cover 7 is made of high light transmittance PC material and is sealed to the light source shell by ultrasonic welding.

[0028] The auxiliary surveying components include a horizontal detection device 12, a microwave rangefinder 13, and a light sensor 14.

The wireless control module supports Bluetooth 5.0 communication protocol, with a control distance of ≤10m and a response latency of ≤100ms.

[0032] The adjustment component 3 includes a vertical angle adjustment rod 10 and a horizontal rotation structure 11; the upper end of the vertical angle adjustment rod 10 is fixedly connected to the power module 2, the lower end of the vertical angle adjustment rod 10 is fixedly connected to the upper end of the horizontal rotation structure 11, and the lower end of the horizontal rotation structure 11 is fixedly connected to the mounting component 4.

[0033] The horizontal rotation structure 11 uses a 28BYJ-48 stepper motor with a reduction ratio of 1:64 and a rated voltage of 5V to drive a gear transmission mechanism with a gear meshing clearance of 0.1-0.2mm. The vertical adjustment uses an SG90 micro servo motor with a torque of 1.8kg・cm, which is connected via a universal joint to achieve angle adjustment. The brightness adjustment is achieved using a WH148 linear potentiometer with a resistance adjustment range of 0-10kΩ and a linear accuracy of ±1%. It is combined with an STM32F103C8T6 microcontroller (72MHz main frequency) and a PWM driver chip to achieve precise brightness control.

[0034] Mounting component 4 includes a threaded connecting post 18, a magnetic interface 19, and a snap-fit ​​interface 20. The threaded connecting post 18 is detachably mounted at the center of the bottom of component 4. The magnetic interface 19 can magnetically engage with the bottom of mounting component 4. The snap-fit ​​interface 20 is detachably mounted at the bottom of mounting component 4. The snap-fit ​​interface 20 has a stretchable and openable structure. The magnetic interface 19 has a silicone anti-slip layer attached to its adsorption surface.

[0035] The main body of mounting component 4 is made of 6061-T6 aluminum alloy with a tensile strength of 310MPa; the threaded connecting post 18 is an M6-M10 compatible external thread; the magnetic interface 19 has an embedded N52 neodymium iron boron magnet (15×5mm, magnetic force ≥50N), and the adsorption surface is covered with a food-grade silicone anti-slip layer with a Shore hardness of 60A; the snap-on interface 20 has an opening range of 5-30mm and is made of elastic engineering plastic through one-piece injection molding.

[0036] The trigger threshold of the light sensor 14 is 20 lux. The microwave rangefinder 13 refreshes the data every 5 seconds to detect the surveying distance, so as to automatically adjust the brightness of the LED light source module 1 according to the ambient light intensity and the surveying distance. The level detection device 12 is a bubble level.

[0037] Working Principle: This device uses LED light source module 1 as the core of light output, provides stable power through power module 2, and achieves precise control of light angle and brightness through adjustment component 3. It is securely connected to various surveying instruments via mounting component 4. It also integrates auxiliary components such as level detection, light sensing, and microwave ranging, realizing both manual and adaptive lighting modes. The overall operation revolves around six core aspects: power drive, light source emission, heat dissipation and protection, angle and brightness adjustment, adaptive sensing, and installation and fixation. The power module 2 has a built-in lithium polymer battery to power the entire device, the power cord 17 enables battery charging, the power switch 8 is the main power on / off control, and the built-in voltage regulator circuit ensures the rated voltage output of each component to avoid equipment failure caused by voltage fluctuations.

[0038] After being powered on, the LED bead 5 emits visible light through the semiconductor electro-optic conversion principle. The aluminum substrate 6 quickly conducts the heat of the LED bead, which is then transferred to the heat dissipation fins 16 via the thermally conductive silicone pad 15. The heat is dissipated through air convection in conjunction with a miniature cooling fan. The detachable transparent light cover 7 protects the LED bead and reduces light scattering, ensuring the light utilization rate.

[0039] The vertical angle adjustment rod 10 of the adjustment component 3 achieves 0-90° vertical adjustment through a micro servo motor and a universal joint. The horizontal rotation structure 11 is driven by a stepper motor and gear transmission to achieve 360° continuous rotation with a rotation accuracy of 0.5° and a positioning error of ≤1°. The brightness adjustment knob 9 drives the linear potentiometer to change the resistance value. The PWM dimming circuit controls the current of the input lamp beads by adjusting the duty cycle of the pulse signal, achieving continuous adjustment of 50-1000 lumens with a brightness adjustment linearity of ≥95%.

[0040] After turning on the power and turning the brightness adjustment knob to the specified position, the adaptive mode is activated; the light sensor 14 detects the ambient light in real time, and automatically turns on the light source when the illuminance is below 20 lux; the microwave rangefinder 13 measures the environmental depth in the surveying direction through the principle of microwave reflection, and automatically adjusts the brightness of the light source according to the "distance-brightness" matching algorithm. When the position changes, the distance is remeasured and the brightness is updated every 5 seconds to achieve dynamic adaptation of the illumination; the horizontal detection device 12 judges the horizontality of the device by the position of the bubble to ensure that the light emission direction of the light source is coaxial with the surveying direction.

[0041] The threaded connecting post 18, magnetic interface 19, and snap-fit ​​interface 20 of the mounting component 4 are adapted to different surveying instrument interface types. The threaded connection achieves precise fixation through thread engagement, the magnetic interface uses a strong magnet to attract metal surfaces, and the snap-fit ​​interface achieves opening and closing fixation through elastic stretching. The silicone anti-slip layer increases friction to prevent the device from sliding or shaking. The engraved lines / color marks on the surface of the mounting component are aligned with the markings to assist in calibrating the light source's emission direction and detection direction.

[0042] The built-in wireless control module can be electrically connected to the adjustment components. Inspectors can send brightness and angle adjustment commands within a 10m range via a mobile APP. After receiving the commands, the main control circuit drives the motor and dimming circuit to complete the adjustment, realizing contactless remote operation and adapting to inspection scenarios that are small and difficult to operate at close range.

[0043] When using this device, first select the threaded connection post 18, magnetic interface 19, or snap-on interface 20 of the mounting component 4 according to the interface type of the surveying instrument, and securely install the device on the instrument. Use the level detection device 12 at the top of the LED light source module 1 to level the device, and calibrate the light emission direction and detection direction of the LED light source module 1 using the alignment marks on the mounting component 4. Then turn on the power switch 8 on the surface of the power module 2, and turn the brightness adjustment knob 9 to the "-" position to activate the adaptive mode. The light sensor 14 and the microwave rangefinder 13 will adjust the ambient light intensity and the surveying distance according to the adaptive mode. The brightness of the LED light source module 1 can be automatically adjusted, or the brightness can be manually adjusted by rotating the brightness adjustment knob 9. The illumination angle can be adjusted by moving the LED light source module 1, in conjunction with the vertical angle adjustment rod 10 and the horizontal rotation structure 11 of the adjustment component 3. The brightness and angle can also be remotely adjusted within a range of 10m via the wireless control module of the device connected to a mobile phone. After the test is completed, the power switch 8 is turned off, the device is disassembled, and the detachable transparent light cover 7 of the LED light source module 1 and the device shell are wiped with a soft cloth dipped in anhydrous ethanol. When the low power indicator light of the power module 2 is lit, it is charged in time via the power cord 17.
