Description

Technical Field

[0001] The present invention relates to the field of traffic lights, and in particular to a temporary traffic light for cooperatively controlling the passage of vehicles and pedestrians. Background Art

[0002] As a core infrastructure for urban road traffic management, traffic light systems shoulder the important responsibilities of coordinating the right of way for pedestrians and vehicles, improving road traffic efficiency, and ensuring traffic safety. However, with the acceleration of urbanization and the surge in traffic volume, the existing technology system has gradually exposed many shortcomings in hardware performance, intelligence level, and collaborative management. It is urgent to solve the following key problems through technical optimization and systemic improvement:

[0003] The existing traffic light system has significant hardware deficiencies. Some lamps display abnormally due to aging or design flaws. For example, compound lamps, which mix red, yellow, and green within the same light-emitting unit, violate national standards. People with color blindness or color weakness find it difficult to distinguish light color based on position, posing a significant safety hazard. Furthermore, problems such as improper installation locations, obstruction by trees or billboards, and irregular arrangement of traffic lights seriously interfere with drivers' visual recognition efficiency. For example, large intersections with six or more lanes in both directions are equipped with only a single set of traffic lights, resulting in insufficient coverage and difficulty in identification.

[0004] Current traffic lights generally rely on fixed timing patterns and lack dynamic responsiveness. During periods of significant traffic fluctuation (e.g., peak and off-peak traffic), fixed cycles cannot adapt to real-time demand, resulting in wasted green light time or excessive wait times. Some intersections have irregular signal transition sequences, such as the lack of a yellow light transition or the use of a non-standard "red and yellow" pattern, which can easily lead to the risk of sudden braking. 3 Furthermore, issues such as insufficient green light duration for pedestrians crossing the street and the misuse of yellow flashing lights on right-turn signals further exacerbate conflicts between pedestrians and vehicles.

[0005] The existing system lacks intelligence, making it difficult to implement real-time data analysis and dynamic control. Older equipment responds slowly, and signal delays during peak hours can cause congestion and even accidents. Although adaptive control technology has been introduced in some areas, it lacks deep integration with navigation systems and intelligent dispatching platforms, creating information silos. For example, traffic lights lacking support from vehicle monitoring systems cannot automatically adjust their timing based on traffic density, resulting in low traffic efficiency.

[0006] In existing technologies, such as patent CN105679059A - Pedestrian Red Light Integrated Signal Light Device Based on Face Recognition, as a signal light, it may have a strong face recognition effect when used temporarily. However, when used temporarily, it cannot judge the direction and stability, has no angle and height control, and cannot adapt to different road conditions.

[0007] Patent CN105679074A - Remotely monitored road traffic lights have the above-mentioned defects. In addition, GPS positioning is not accurate enough in densely populated urban areas or in bad weather, which may affect device positioning and wireless charging collaboration.

[0008] On the other hand, the traffic lights of the above patents are unable to realize the multi-mode light information interaction function and enhance the visual perception ability of drivers and pedestrians. Summary of the Invention

[0009] This application proposes a temporary traffic light that coordinates vehicle and pedestrian traffic. This design uses a motorized drive to adjust height to accommodate varying lane widths and tilts to accommodate sloping roads, resolving the rigid deployment issues of traditional fixed traffic lights. The multifunctional lamp head module addresses the limitations of traditional traffic lights, which lack the flexibility to deploy and interact with multiple information in temporary scenarios.

[0010] In a first aspect, the present application provides a temporary traffic signal light for coordinated control of vehicle and pedestrian traffic, comprising:

[0011] Base assembly;

[0012] The retractable support has one end fixedly connected to the base assembly and the other end connected to the multifunctional lamp head module. The retractable support is controlled by a forward and reverse motor and an angle limiter to control the flip angle.

[0013] The multifunctional lamp head module includes a detachable lamp group equipped with pedestrian signal lights and vehicle signal lights, as well as an LED display screen and a ring light strip.

[0014] In this application, in temporary traffic scenarios, the signal lights can be controlled through the positive and negative electrodes and angle limiters on the retractable pillars to achieve multi-angle automatic control and highly customized adjustment. For the multi-functional lamp head module, the detachable and capable pedestrian signal lights can achieve multi-mode information interaction, while also providing targeted lighting and signal indication for pedestrians and vehicles.

[0015] In combination with the first aspect, the base assembly includes a counterweight structure and a temporary charging port disposed at the bottom;

[0016] The base assembly is made of iron-based alloy;

[0017] A motor control cabin, a battery pack and a solar energy conversion device are arranged inside the base assembly.

[0018] In this application, the base is made of iron-based alloy and has a built-in counterweight structure, combined with a solar energy conversion device and a battery pack to achieve all-weather power supply, improve structural stability, energy self-sufficiency and environmental protection and energy saving

[0019] In combination with the first aspect, the solar energy conversion device includes: a predictive charge and discharge controller and a dual-channel emergency power supply switching device; wherein,

[0020] The predictive charge and discharge controller is used to obtain meteorological data, determine the real-time temperature difference, and determine the supplementary power supply based on the real-time temperature difference.

[0021] The dual-channel emergency power supply switching device includes a power supply supervision channel based on the LoRa protocol and a wireless reverse charging channel based on the minimum battery capacity response.

[0022] In this application, a dual-channel emergency power supply switching device (LoRa protocol supervision channel + wireless reverse charging channel) ensures continuous power supply in extreme weather conditions, enhances the redundancy of the power supply system, and avoids signal light failure due to a single fault.

[0023] In combination with the first aspect, the multifunctional lamp head module further includes a voice prompt unit, which includes an ambient noise detection component, a multi-period volume adjuster, and an emergency broadcast interface; wherein,

[0024] The environmental noise detection component is used to adaptively adjust the voice broadcast frequency band based on the noise spectrum characteristics collected in real time;

[0025] The multi-period volume regulator is used to coordinate the output of different multi-modal warning strategies during different traffic periods. The multi-modal warning strategies include voice broadcast, dynamic pattern warning on LED display, and strobe light strip.

[0026] The emergency broadcast interface is used to automatically match the preset voice content template when receiving emergency voice broadcast content based on pre-configured volume thresholds during peak and off-peak hours.

[0027] In this application, the voice prompt unit realizes adaptive warning through noise detection and multi-period volume adjustment, which can reduce environmental noise interference and improve the clarity of pedestrian and driver perception of signals.

[0028] In combination with the first aspect, the LED display screen includes:

[0029] Environmental perception module, integrating light intensity sensor and raindrop detector, is used to monitor the monitoring data of temporary traffic control area in real time; the monitoring data includes light intensity and weather conditions;

[0030] A dynamic display control unit is used to determine the display content based on the monitoring data and generate display warning information;

[0031] The multimodal collaborative module detects an approaching emergency vehicle and switches the linked ring light strip to red strobe light. At the same time, the LED display generates a guidance cursor and synchronizes it with the emergency broadcast content of the voice prompt unit.

[0032] In this application, the environmental perception module (light intensity / raindrop detection) of the LED display screen is linked to dynamic display control to adjust the warning information in real time to adapt to the warning needs of severe weather such as rain and fog.

[0033] In combination with the first aspect, the annular light strip includes:

[0034] The phase synchronization control unit is synchronized with the phase clock of the traffic signal in real time. When the red light countdown begins, the time synchronization contraction function is activated to shrink the ring light strip at a predetermined rate.

[0035] Adaptive anti-glare coating, composed of nano-scale silica particles and photochromic materials. When the ambient light intensity reaches a preset intensity, the coating's transmittance decreases until diffuse glare is suppressed.

[0036] The dynamic arrow indicator module integrates millimeter-wave radar to detect vehicle turning intentions in real time and generates a deformable LED arrow based on the vehicle trajectory prediction results. The arrow length is negatively correlated with the vehicle distance.

[0037] The multi-source collaborative control unit forces the annular light strip to switch to a high-frequency red and blue alternating flashing mode when the projection LED light group activates the avoidance guidance light strip, and forms a time-space synchronized warning with the emergency broadcast content of the voice prompt unit.

[0038] In this application, the phase synchronization control of the ring light strip and the adaptive anti-glare coating reduce glare interference at night, improve accuracy, and adapt to the warning needs of severe weather such as rain and fog.

[0039] In combination with the first aspect, the retractable support is connected to the base through a hollow circular tube structure, and a power transmission channel and a gravity sensor for controlling the multifunctional lamp head module are arranged inside; wherein,

[0040] When the gravity sensor tilts beyond the preset safety threshold, the retractable support will be triggered to automatically retract.

[0041] In this application, the retractable support has a built-in gravity sensor, which automatically retracts when the tilt exceeds a threshold value, thereby enhancing the structural safety and preventing the equipment from tipping over and causing a secondary accident.

[0042] In combination with the first aspect, the base assembly has a built-in counterweight compartment and a reinforcement assembly, and the center of gravity can be adjusted by injecting / discharging liquid;

[0043] The reinforcement assembly consists of a sliding sleeve, multiple sets of hinged rods and a support rod. The sliding sleeve is mounted on the outer wall of the column and can slide along its axis. The end of the support rod is provided with an adjustable anchor claw, which can be embedded in the ground to form a triangular support when unfolded.

[0044] In this application, the seat-mounted weight bin and reinforcement components (sliding sleeve + hinged rod) support center of gravity adjustment, which improves the stability of the equipment on soft ground or slopes and adapts to complex terrain deployment.

[0045] In combination with the first aspect, the multifunctional lamp head module also has a built-in 5G communication module and Beidou positioning unit, and receives the green wave coordination control solution sent from the cloud.

[0046] In this application, 5G communication and Beidou positioning are integrated, green wave coordination instructions are received from the cloud, and traffic lights are controlled intelligently to achieve dynamic optimization of regional traffic flow and reduce congestion.

[0047] In combination with the first aspect, the multifunctional lamp head module is integrated with a pedestrian touch button, which generates a countdown signal when the pedestrian touch button is triggered and uploads it to the control terminal;

[0048] The control terminal dynamically adjusts the pedestrian passage interval period according to the traffic volume and sets the minimum application interval time threshold.

[0049] In this application, people touch buttons to link countdown signal uploads, dynamically adjust the traffic interval, and allocate more reasonable time for pedestrians to cross the street, reducing waiting anxiety and improving pedestrian safety.

[0050] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention.

[0064] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0065] Example 1:

[0066] like Figure 1 and Figure 2 As shown, the present application provides a temporary traffic signal light for coordinated control of vehicle and pedestrian traffic, including:

[0067] Base assembly 1; used to provide stability and mobility in temporary traffic scenarios, such as construction sections and emergencies.

[0068] The retractable support 2 has one end fixedly connected to the base assembly 1 and the other end connected to the multifunctional lamp head module 4. The retractable support 2 is controlled by a forward and reverse motor and an angle limiter to control the flip angle. The retractable support 2 is fixed to the multifunctional lamp head module 4 via a T-shaped connecting column 3. In this application, the motor drives the height-adjustable retractable support 2 to rise and fall, adapting to different lane widths and flip angles. By adjusting the flip angle, when dealing with inclined roads, the height is adjusted by the forward and reverse electrodes, and the angle is controlled by the angle limiter, which solves the problem of rigid deployment of traditional fixed signal lights. Figure 1 9 is the cover plate of the base assembly 1.

[0069] The multifunctional lamp head module 4 includes a detachable light assembly equipped with pedestrian and vehicle signal lights, an LED display, and a circular light strip. The LED display can dynamically display countdowns and warnings, such as "slow down" and "detour" signals, to compensate for the single-color nature of traditional signal lights. The circular light strip can achieve a transition between different light colors through color gradients or flashing modes.

[0070] This application is a temporary signal light, which is used to coordinate and synchronize the phases of the signal lights that temporarily control the flow of vehicles with the signal lights that control the flow of people. Through the flip-up design, it can be placed in the trunk of a car, so there is no need for a special vehicle for transportation. In terms of product intelligence, it has a multi-functional lamp head module, an LED display, and accepts timing plans issued by the command and control center.

[0071] The base assembly of this application is made of high-strength aluminum alloy, with built-in counterweights and moving wheels, such as universal wheels, to ensure the stability and portability of the equipment.

[0072] The base can be powered by solar panels or batteries to support long-term outdoor operations;

[0073] Retractable support: driven by a forward and reverse motor, combined with an angle limiter to achieve precise control of height and tilt angle.

[0074] The pillar adopts waterproof and dustproof design to adapt to adverse weather conditions.

[0075] Multifunctional lamp head module: including: pedestrian / vehicle signal light: adopts high-brightness LED light source, supports independent display of red, yellow and green colors, and the modular design is easy to disassemble and maintain.

[0076] LED display: Generate dynamic arrows or text on the display, such as stop and go, to enhance warning effects at night or in low visibility conditions.

[0077] Ring light strip: Set around the lamp head, it uses gradient light to indicate the signal switching countdown, reducing the risk of misjudgment for drivers and pedestrians.

[0078] Built-in sensors, such as cameras, infrared, or geomagnetic sensors, monitor traffic flow and pedestrian demand in real time, and combine them with intelligent algorithms to optimize signal timing. For example, when pedestrian demand is low, the green light duration for vehicles can be extended to improve traffic efficiency on the main road.

[0079] When congestion is detected, the signal light sequence will be automatically switched or a yellow flashing warning will be triggered.

[0080] Remote network control: supports 5G / Bluetooth communication and is linked to the city’s traffic signal system to achieve regional coordinated control, such as green wave belts.

[0081] The telescopic design of the pillars in this application can adapt to different road conditions, such as narrow streets or wide main roads, to ensure the visibility of traffic lights. It supports rapid equipment transportation and can be set up and put into operation in a short time. It is suitable for construction sections, emergency scenarios or peak periods in scenic spots. Through pedestrian detection sensors and traffic flow analysis algorithms, signal timing is dynamically adjusted to reduce invalid green light time and improve road traffic efficiency. It also supports multiple modes such as timing control, manual intervention, and green wave coordination to adapt to different time periods and traffic scenarios.

[0082] Example 2:

[0083] like Figure 3 As shown, the base assembly of the present application includes a counterweight structure and a temporary charging interface provided at the bottom;

[0084] The base assembly 1 is made of an iron-based alloy. In actual implementation, the base assembly incorporates a built-in sliding counterweight and gravity sensor. The gravity sensor monitors center offset in real time, while the drive motor determines the corresponding coordinate position of the counterweight based on the offset angle, improving stability on complex terrain. The iron-based alloy base utilizes a hollow honeycomb structure. Internal control circuits connect the various cells within the structure. Beneath the cells, a counterweight slide rail, based on a gravity coordinate system, is located. This circular rail encircles the base assembly, and the counterweight is mounted on the rail.

[0085] Inside the base assembly 1, a motor control cabin, battery pack, and solar energy conversion device are housed. The solar energy conversion device integrates a dual-axis solar tracking module and MPPT to track maximum power and determine the illumination angle that achieves maximum tracking power, enabling real-time adjustment of the solar panel's orientation. Discharge strategies are optimized through built-in communication components, such as LoRa wireless communication and cloud collaboration.

[0086] The counterweight structure of the present application adopts an iron-based alloy material and combines its shape memory effect to achieve dynamic self-adjustment function.

[0087] For example, when the base is slightly deformed by external loads, it is excited by local heating;

[0088] For example: solar energy conversion devices provide power and heating, and iron-based alloy materials can generate restoring stress, actively restore the structural shape and improve anti-overturning ability.

[0089] Compared to traditional counterweights that rely solely on passive mass, this application upgrades from static balance to dynamic adaptation. Traditional counterweights are mostly made of high-density materials such as cast iron, while the introduction of iron-based alloys combines the functionality and structure of the material, achieving intelligent counterweights through thermal excitation.

[0090] Example 3:

[0091] like Figure 4As shown, the solar energy conversion device of the present application includes: a predictive charge and discharge controller and a dual-channel emergency power supply switching device; wherein,

[0092] The predictive charge and discharge controller is used to obtain meteorological data, determine the real-time temperature difference, and determine the supplementary power supply based on the real-time temperature difference; for example: integrating the LSTM neural network, inputting the temperature, humidity, wind speed and real-time temperature difference in historical meteorological data, predicting the efficiency decay rate of photovoltaic panels in the next 24 hours, and dynamically adjusting the charge and discharge power distribution.

[0093] The dual-channel emergency power supply switching device includes a power supply supervision channel based on the LoRa protocol and a wireless reverse charging channel based on the minimum battery capacity response. The dual-channel emergency power supply switching device also monitors voltage fluctuations and electromagnetic interference in real time, enabling directional transmission for different traffic lights. When low battery is predicted, this application automatically reduces the green light duration of non-critical phases to prioritize pedestrian crossing signals.

[0094] This application uses real-time meteorological data, such as light intensity and temperature differences, to enable a predictive charge-discharge controller to dynamically adjust the charge-discharge strategy based on machine learning algorithms within AI algorithms. For example, combined with predictive control, the controller can anticipate power generation fluctuations and optimize the charge-discharge timing of the energy storage system, reducing energy waste and improving solar energy utilization. For example, when temperature differences are large, supplemental power is activated to prevent over-discharge or over-charging of the battery.

[0095] By adjusting the power supply strategy according to the real-time temperature difference, it can adapt to the battery performance degradation problem in different environments. For example, high temperature causes the internal resistance of the battery to increase, thereby extending the battery life.

[0096] The LoRa protocol's power monitoring channel enables low-power, long-distance monitoring of system status, such as battery voltage and load power, and remotely alerts users of faults or anomalies, such as excessive line loss or component overheating, via the cloud platform. For example, the protocol's communication capabilities support remote troubleshooting, and when combined with the LoRa channel's real-time data transmission, they enhance system security.

[0097] A wireless reverse charging channel that responds to minimum battery capacity automatically draws emergency power from a backup power source, such as the mains or other energy storage units, when the main battery capacity falls below a threshold, preventing system failure. Wireless reverse charging further reduces reliance on physical wiring.

[0098] The dual-channel switching mechanism, combined with supervision and reverse charging, provides redundant protection and reduces the risk of single-point failure. For example, the automatic bidirectional switching function of the switching grid-connected system prevents power outages caused by grid or PV system failures.

[0099] This embodiment combines weather forecasting with dual-channel emergency switching, achieving a collaborative optimization approach of dynamic prediction and proactive response. For example, the predictive controller adjusts charging and discharging plans in advance, while the emergency channel quickly intervenes in the event of an anomaly, improving stability.

[0100] Example 4:

[0101] like Figure 5 As shown, the multifunctional lamp head module of the present application also includes a voice prompt unit, which includes an ambient noise detection component, a multi-period volume regulator, and an emergency broadcast interface; wherein,

[0102] The environmental noise detection component is used to adaptively adjust the voice broadcast frequency band based on the noise spectrum characteristics collected in real time; the environmental noise detection component deploys a microphone array to build a three-dimensional model of the acoustic environment, and uses beamforming technology to directionally enhance voice broadcast while suppressing noise interference frequency bands.

[0103] The multi-period volume regulator is used to coordinate the output of different multi-modal warning strategies during different traffic periods. The multi-modal warning strategies include voice broadcast, dynamic pattern warning generated by LED display, and strobe light strip.

[0104] The emergency broadcast interface is used to automatically match the preset voice content template when receiving emergency voice broadcast content based on pre-configured volume thresholds during peak and off-peak hours.

[0105] The environmental noise detection component of this application analyzes the real-time noise spectrum characteristics, such as low-frequency mechanical noise or high-frequency human voice interference, and dynamically adjusts the voice broadcast frequency band to avoid the main noise frequency band and improve voice clarity. For example, in an industrial scenario, if the environmental noise is mainly low-frequency, the system will automatically enhance the output of the medium and high-frequency voice bands to avoid the sound being masked. The multi-period volume adjuster outputs differentiated warning strategies according to the traffic period, such as peak / off-peak. For example: During peak hours: dynamic patterns on the LED display, such as flashing arrows, are combined with high-frequency voice broadcasts to strengthen visual and auditory dual warnings; during non-peak hours: only low-frequency ring light strips are enabled to flash to reduce energy consumption and light pollution.

[0106] The emergency broadcast interface of this application automatically matches the voice template content through the preset peak / non-peak volume threshold.

[0107] For example, during peak hours, use concise instruction templates, such as "Please evacuate urgently," and use the maximum volume threshold to cover the ambient noise;

[0108] During off-peak hours: Enable detailed guidance templates, for example: public transportation is 50 meters to the left and uses a medium volume to reduce disturbance.

[0109] Traditional voice devices only support fixed wake-up words and commands, but this embodiment deeply combines emergency scenarios with time period strategies to achieve dual adaptation of content and volume, thereby improving emergency response efficiency.

[0110] Example 5:

[0111] like Figure 6 As shown, the LED display screen includes:

[0112] Environmental perception module, integrating light intensity sensor and raindrop detector, is used to monitor the monitoring data of temporary traffic control area in real time; the monitoring data includes light intensity and weather conditions;

[0113] When implementing IDE, millimeter-wave radar and infrared thermal imaging are installed in the multi-function lamp head module to detect pedestrian / vehicle trajectories and road icing conditions. Based on the LSTM model, traffic trends in the future are predicted and display content is dynamically generated, such as providing early warning of flooded areas.

[0114] A dynamic display control unit is used to determine the display content based on the monitoring data and generate display warning information;

[0115] The multimodal collaborative module switches to a red strobe light when an approaching emergency vehicle is detected. Simultaneously, the LED display generates a guidance cursor, synchronized with the emergency announcement from the voice prompt unit. In actual implementation, the LED display communicates with surrounding intelligent connected vehicles (V2X), receiving vehicle speed and steering intent data to generate a dynamic guidance cursor. For example, a "Warning Pedestrian" arrow appears for right-turning vehicles, synchronized with the announcement.

[0116] This application uses an environmental sensing module that integrates a light intensity sensor and a raindrop detector to monitor light intensity and weather conditions in temporary traffic control areas in real time. Combined with environmental sensing technology, the module can dynamically adjust projection parameters (such as light intensity and projection area) to ensure that warning information remains visible in different environmental conditions (such as strong sunlight and rain) while avoiding energy waste.

[0117] The dynamic display control unit generates real-time warning information based on environmental data, such as whether there are pedestrians, and configures different warning lights; when the LED display screen and the annular light strip on one side show a red light, the LED will show green for pedestrians to pass, and on the other adjacent side, the annular light strip will show green for green light, and the LED will show red for no passage.

[0118] This application is also equipped with projection spotlight technology to achieve precise synchronization of warning light strips and voice broadcasts, improving the driver's reaction speed and safety guidance effect.

[0119] When an emergency vehicle is detected approaching, the system links the ring light strip through the multimodal collaborative module, flashes red, and the LED display generates a guidance cursor and voice prompts for guidance.

[0120] The human infrared sensing system and intelligent projection interaction technology, this multi-signal collaborative mechanism not only strengthens visual warnings, such as: high-priority identification of red flashing, but also provides redundant information through voice broadcasting, significantly improving the warning effect in emergency scenarios.

[0121] This application combines a light intensity sensor with a raindrop detector, and adjusts projection parameters accordingly, addressing the lack of adaptability of traditional traffic warning devices in complex weather conditions. For example, rainy days can reduce the visibility of the projected light strip on the ground. In this case, the system can automatically increase the projection brightness or switch to strobe mode.

[0122] Example 6:

[0123] like Figure 7 As shown, the annular light strip includes:

[0124] The phase synchronization control unit is synchronized with the phase clock of the traffic signal in real time. When the red light countdown begins, the time synchronization contraction function is activated to shrink the ring light strip at a predetermined rate.

[0125] Adaptive anti-glare coating, composed of nano-scale silica particles and photochromic materials, reduces light transmittance when ambient light intensity reaches a preset level, until diffuse glare is suppressed. During implementation, a silane coupling agent containing microencapsulated repair agents is added to the adaptive anti-glare coating. When cracks appear in the coating due to ultraviolet light or mechanical damage, the microcapsules rupture and release the repair agent, causing self-repair through a photocatalytic reaction.

[0126] The dynamic arrow indicator module integrates millimeter-wave radar to detect vehicle turning intentions in real time and generates a deformable LED arrow on the LED display based on the vehicle trajectory prediction results. The arrow length is negatively correlated with the vehicle distance.

[0127] The multi-source collaborative control unit forces the ring light strip to switch to a high-frequency red and blue alternating flashing mode when the LED display starts the avoidance guidance light strip display, and forms a time-space synchronized warning with the emergency broadcast content of the voice prompt unit.

[0128] In real time, the traditional ring light strip only displays statically, and the contraction rate matches the pedestrian's walking speed. The remaining time of travel is intuitively conveyed by the speed of the aperture contraction, reducing the probability of pedestrian violations. The photochromic properties of the anti-glare coating automatically reduce the transmittance in strong light, making the LED brightness from 1000cd / m 2 Attenuation to 300cd / m 2To prevent driver distraction from glare, millimeter-wave radar detects vehicle steering angle errors, and a deformable LED arrow dynamically expands and contracts via a flexible substrate, eliminating the problem of traditional fixed arrows misleading vehicles changing lanes. When the LED display generates a guiding avoidance cursor, the alternating red and blue flashes of the ring light strip create a cross-modal resonance with the sound waves of the voice announcement, enhancing driver concentration.

[0129] Example 7:

[0130] like Figure 8 As shown, the retractable support is connected to the base through a hollow circular tube structure, and a power transmission channel and a gravity sensor for controlling the multifunctional lamp head module are set inside; wherein,

[0131] When the gravity sensor tilts beyond the preset safety threshold, the retractable support will be triggered to automatically retract.

[0132] When the support pillar of this application is tilted beyond a preset threshold due to external forces, such as strong winds or collisions, the gravity sensor triggers the forward and reverse motors to quickly retract the support pillar to avoid the risk of tipping over.

[0133] For example, in typhoon weather, traditional fixed pillars are prone to collapse due to wind force. This design uses real-time monitoring and automatic response.

[0134] In actual implementation:

[0135] The gravity sensor integrates a three-axis gyroscope and tilt sensor, and uses V2X communication to receive trajectory data from surrounding vehicles to build a three-dimensional posture model. When a tilt angle greater than 15° and a vehicle distance less than 3 meters is detected, retraction is triggered. If only the tilt angle exceeds the limit but no vehicle is approaching, an alarm is issued without retraction. A shape-memory polymer coating can also be applied to the inner wall of the hollow circular tube. When retraction is detected, the tube wall is restored to its original shape through heating and solar power.

[0136] Uninterrupted Power Transmission: The power transmission channel is integrated within the hollow tube. Slip rings or flexible cables maintain continuous power during retraction, eliminating the risk of breakage associated with traditional external cables due to mechanical movement. Integrating power transmission, sensor signal lines, and mechanical retraction mechanisms within a single hollow tube reduces exposed external components and lowers maintenance costs. For example, traditional support columns require additional cable protection.

[0137] The safety design of traditional retractable supports mostly relies on physical limiters or independent tipping sensors, while this embodiment deeply couples the gravity sensor, power transmission channel and the support retraction action.

[0138] The power lines within the hollow tube also power the gravity sensor, eliminating the need for a separate power module. Data directly drives the motor to retract, eliminating the need for an external controller. Pluggable terminal blocks are installed within the hollow tube to support hot-swappable cable replacement. Each section of the hollow tube has built-in standardized interfaces, allowing for quick module replacement in the event of a fault.

[0139] Example 8:

[0140] like Figure 9 As shown, the base assembly has built-in counterweight chambers and reinforcement components, and the center of gravity can be adjusted by injecting / discharging liquid. In actual implementation, the counterweight chamber integrates a pressure sensor and a gyroscope to monitor the base posture in real time, and dynamically adjusts the counterweight distribution in combination with a liquid pump control algorithm: when a tilt angle greater than 5° is detected, water is injected into the high-side counterweight chamber and drained from the low-side chamber. The articulated rods simultaneously deploy the support rods, and the anchor claws adaptively adjust the embedding depth according to the hardness of the ground.

[0141] The reinforcement assembly consists of a sliding sleeve, multiple sets of articulated rods, and support rods. The sliding sleeve is mounted on the outer wall of the column and can slide along its axis. The support rods are terminated with adjustable anchor claws that, when deployed, embed into the ground to form a triangular support. The anchor claws are coated with a shape-memory polymer coating. When loose soil is detected, the coating expands through heating and solar power, forming a mechanical interlocking structure.

[0142] This application uses the liquid injection / discharge function of the counterweight bin to achieve rapid adjustment of the center of gravity of the base. At the same time, combined with the triangular support structure formed by the articulated rod and the support rod, it can simultaneously complete center of gravity compensation and mechanical reinforcement under complex foundation conditions. For example, when constructing on a soft soil foundation, the liquid is discharged to reduce the weight and prevent sinking, and at the same time, the anchor claws are deployed to embed into the deep stabilization layer. The sleeve slides along the axis of the column, allowing the angle of the support rod to be freely adjusted as the terrain changes. For example, when constructing on inclined ground, the sleeve can be moved to different heights of the column, so that the articulated rod forms an asymmetric triangular support to adapt to the inclination angle. The adjustable anchor claws are directly embedded in the ground through mechanical deployment. Compared with traditional concrete pouring reinforcement, they can reduce auxiliary operation time and avoid the risk of formwork offset.

[0143] Example 9:

[0144] like Figure 10 As shown, the multifunctional lamp head module also has a built-in 5G communication module and Beidou positioning unit, and receives the green wave coordination control solution sent from the cloud.

[0145] This application uses the low-latency characteristics of 5G to achieve real-time communication between the cloud and traffic lights. Combined with Beidou's high-precision positioning, it can dynamically optimize regional traffic signal timing and alleviate congestion. Beidou positioning can obtain real-time vehicle location and speed data, and combined with cloud-based traffic models, it can generate more accurate green wave band control strategies to improve traffic efficiency.

[0146] Example 10:

[0147] like Figure 11 As shown, the multifunctional lamp head module is integrated with a pedestrian touch button, which generates a countdown signal when the pedestrian touch button is triggered and uploads it to the control terminal;

[0148] The control terminal dynamically adjusts the pedestrian passage interval period according to the traffic volume and sets the minimum application interval time threshold.

[0149] This application dynamically adjusts the pedestrian passage interval according to the real-time traffic flow to avoid the waste of resources caused by fixed cycles. The minimum interval threshold prevents signal confusion caused by frequent triggering and balances pedestrian needs with traffic efficiency.

Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
