Description

TECHNICAL FIELD

[0001] The present application relates to the field of municipal engineering, in particular to a city viaduct anti-glare device and design method based on a three-dimensional real scene model. BACKGROUND

[0002] The city viaduct brings smooth traffic to the city, but also causes hidden dangers to viaduct driving safety due to the refraction of light by the glass curtain wall of the buildings on both sides of the viaduct. At present, the design of viaducts at home and abroad usually only completes the linear design, roadbed and pavement design, intersection design, along-line auxiliary facility design and corresponding ramp design of the viaduct. These designs are all based on the design of viaduct driving safety within the road land boundary. The influence factors on viaduct driving safety outside the road land boundary are basically not within the consideration range, and the viaduct driving safety problem caused by the refraction of light by the glass curtain wall of the buildings on both sides of the viaduct is often ignored. The refraction of light by the glass curtain wall of the buildings on both sides of the viaduct is also a very common problem in the process of city development. Although there are sound barriers on both sides of some viaducts, the sound barriers are mainly used for sound insulation and noise reduction, and the transparent screen body of the sound barriers is mainly made of PC plate, glass steel plate and acrylic plate, all of which have high light transmittance and cannot block the reflected glare of the glass curtain wall. SUMMARY

[0003] The purpose of the present application is to overcome the above-mentioned defects and to prevent the refraction of light by the glass curtain wall onto the road by replacing the transparent screen body of the sound barrier with light-adjustable glass.

[0004] In order to achieve the above-mentioned purpose, the present application is implemented as follows:

[0005] A city viaduct anti-glare device and design method based on a three-dimensional real scene model, comprising

[0006] Step 1, collect relevant technical data of the viaduct and its surroundings;

[0007] Step 2, establish a three-dimensional real scene model by oblique photography;

[0008] Step 3, verify the influence of glare caused by the glass curtain wall of the surrounding buildings on the viaduct driving safety in the road section where the sound barrier needs to be set, and if necessary, organize expert demonstration to determine the specific influence of the glare caused by the surrounding buildings or structures on the viaduct driving safety;

[0009] Step 4, if the influence of the glare on the viaduct driving safety is within a controllable range and the glare problem does not cause driving safety accidents, the glare problem is not considered;

[0010] Step 5, if glare may cause safety accidents of elevated driving, firstly consider whether the adverse effects of glare on elevated driving safety can be avoided in the early stage of the project;

[0011] Step 6, if the influence of glare on driving safety is difficult to avoid, consider the optimization design of adding anti-glare function to the sound barrier;

[0012] Step 7, in the section needing anti-glare design, the transparent screen body material of the sound barrier is replaced with light control glass, and the transparent and opaque states of the light control glass are switched through light control or remote network control, without affecting the sound insulation function of the sound barrier;

[0013] Step 8, the light intensity of the local area is collected by the light control probe, and the limit value of the light control light control glass is set according to the collected light intensity, that is, when the sunlight reflected by the glass curtain wall exceeds the set limit value, the light control glass automatically switches and presents an opaque appearance state, effectively controlling the influence of glass curtain wall reflected glare on driving safety;

[0014] Step 9, the switching time of the light control glass is set according to different seasons, and the power is set off from 6am to 6pm through the network, at this time the liquid crystal molecules in the electric control light control glass will present irregular distribution state, and present opaque appearance state; while the liquid crystal molecules in the light control glass present neat arrangement after being powered on at night, and the light can freely penetrate, at this time the light control glass presents transparent state instantaneously; in view of the characteristics that the light control glass needs to be powered off during the day and powered on at night, solar panels can be installed to supply power for the light control glass, which not only reduces the cost and saves energy, but also meets the anti-glare requirements;

[0015] Step 10, the position and interval of the material optimization area are adjusted considering the effect of shielding light, economy and transverse visibility requirements;

[0016] Step 11, the elevated line is tested and run, if the design requirements cannot be met, return to step 10 until the design requirements are met.

[0017] The present application prevents the glass curtain wall from refracting light onto the road by replacing the transparent screen body of the sound barrier with light control glass, and realizes intelligent control through light control or remote network control. This is conducive to improving the safety and comfort of elevated driving, and effectively protecting the safety of people's life and property. BRIEF DESCRIPTION OF DRAWINGS

[0022] Step 2, establish a three-dimensional real scene model by oblique photography;

[0023] Step 3, verify the influence of glare caused by glass curtain walls of surrounding buildings on the elevated road safety in a road section where a sound barrier is needed to be arranged, and if necessary, organize expert demonstration to determine the specific influence of the glare caused by the surrounding buildings or structures on the elevated road safety;

[0024] Step 4, if the influence of the glare on the elevated road safety is within a controllable range and the glare does not cause a traffic safety accident, the glare problem is not considered;

[0025] Step 5, if the glare can cause a traffic safety accident, firstly consider whether the adverse influence of the glare on the elevated road safety can be avoided in the early stage of the project;

[0027] Step 7, in a road section where anti-dazzle design is needed, the transparent screen body material of the sound barrier is replaced by light control glass, the transparent and opaque states of the light control glass are switched by light control or remote network control, and the sound insulation function of the sound barrier is not affected;

[0028] Step 8, the local illumination is collected by a light control probe, and the limit value of the light control glass is set according to the collected illumination, that is, when the sunlight reflected by the glass curtain wall exceeds the set limit value, the light control glass is automatically switched and presents an opaque appearance state, thereby effectively controlling the influence of the reflected glare of the glass curtain wall on the traffic safety;

[0029] Step 9, the switching time of the light control glass is set according to different seasons, the power is turned off from 6 am to 6 pm through network setting, at this time, the liquid crystal molecules in the electric control light control glass present an irregular scattered state and present an opaque appearance state, and after the light control glass is powered on at night, the liquid crystal molecules present an orderly arrangement and the light can freely penetrate, at this time, the light control glass presents a transparent state instantaneously; in view of the characteristics that the light control glass needs to be powered off during the day and powered on at night, a solar panel can be installed to supply power for the light control glass, which not only reduces the cost and saves energy, but also meets the anti-dazzle requirement;

Claims

1. A method for anti-glare design of urban elevated roads based on a 3D reality model, characterized by: include Step 1: Collect relevant technical data on the viaduct and its surrounding area; Step 2: Establish a 3D reality model using oblique photogrammetry; Step 3: Verify the impact of glare caused by the glass curtain walls of surrounding buildings on the safety of elevated road traffic in sections where sound barriers need to be installed, and organize experts to conduct demonstrations to determine the specific impact of glare caused by surrounding buildings or structures on the safety of elevated road traffic. Step 4: If the impact of glare on the safety of driving on elevated roads is within a controllable range and will not cause driving safety accidents due to glare, then the glare problem will not be considered. Step 5: If glare may cause safety accidents while driving on elevated roads, first consider whether the adverse effects of glare on the safety of driving on elevated roads can be avoided in the early stages of the project. Step 6: If the impact of glare on driving safety is difficult to avoid, consider optimizing the design of the sound barrier by adding anti-glare function. Step 7: In road sections where anti-glare design is required, replace the transparent screen material of the sound barrier with dimming glass. Switch between transparent and opaque states of the dimming glass through light control or remote network control, without affecting the sound insulation function of the sound barrier. Step 8: Use a light-controlled probe to collect local illuminance, and set a limit for the light-controlled dimming glass based on the collected illuminance. That is, when the sunlight reflected by the glass curtain wall exceeds the set limit, the dimming glass will automatically switch to an opaque appearance, effectively controlling the impact of glare reflected by the glass curtain wall on driving safety. Step 9: Set the switching time of the dimming glass according to different seasons. Set the power off from 6:00 AM to 6:00 PM via the network. At this time, the liquid crystal molecules inside the electronically controlled dimming glass will be irregularly scattered, presenting an opaque appearance. When the dimming glass is powered on at night, the liquid crystal molecules inside will be neatly arranged, and light can pass through freely. At this time, the dimming glass will instantly become transparent. Given that the dimming glass needs to be powered off during the day and powered on at night, installing solar panels to power the dimming glass will reduce costs, save energy, and also meet the anti-glare requirements. Step 10: Considering the effect of light blocking, economy, and the requirements of horizontal visibility, adjust the position and spacing of the material optimization area; Step 11: Conduct a trial run on the entire elevated road. If the design requirements are not met, return to step 10 until the design requirements are met.
