Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of traffic signals, in particular to a traffic road ghost head warning light. BACKGROUND

[0002] In urban traffic roads, there are widely existing pedestrian crossings without traffic lights or road sides with green plants and other sight-obstructing sections. When pedestrians or non-motor vehicles cross the road, motor vehicle drivers are difficult to timely detect due to visual blind area, resulting in frequent traffic accidents, which is called "ghost head".

[0003] At present, traffic management departments usually install monitoring cameras at accident-prone intersections for post-facto evidence collection or set ordinary warning signs to remind drivers. However, these measures have obvious limitations: monitoring cameras lack real-time warning function and cannot effectively prevent accidents before they occur; ordinary warning signs only provide static prompts and cannot dynamically adapt to the complex and variable traffic conditions at intersections. The root cause lies in the fact that existing technical means cannot achieve real-time and accurate detection and two-way warning of pedestrians and vehicles at intersections. On the one hand, traditional monitoring equipment mainly focuses on post-facto evidence collection and does not have effective sensors and control systems to identify and warn potential dangers in advance; on the other hand, static warning signs cannot perceive real-time dynamic information at intersections and cannot provide timely and accurate traffic reference for drivers and pedestrians, thus failing to meet the needs of actual traffic safety management. SUMMARY

[0004] (I) Technical problems solved In view of the deficiencies of the prior art, the present application provides a traffic road ghost head warning light, which solves the problems raised in the background art.

[0005] (II) Technical solutions To achieve the above purpose, the present application is implemented by the following technical solutions: a traffic road ghost head warning light, comprising a detection device, a warning device and a control device, the detection device comprising at least two groups of laser transmission sensors, ultrasonic ranging sensors and networkable monitoring cameras, for detecting the approach of pedestrians, non-motor vehicles and vehicles at intersections; The warning device comprises an LED light strip, a full-color LED dot matrix display screen and a motor vehicle display screen, for real-time warning of passing vehicles and pedestrians; The control device comprises a control circuit board and a power management circuit, for collecting signals of the detection device, data processing and logical judgment, and controlling the action of the warning device.

[0006] Preferably, the laser beam sensor is installed on both sides of the intersection. When a pedestrian or non-motorized vehicle blocks the laser beam, a signal change is triggered. The control device illuminates an LED strip at the corresponding height based on the signal and displays the pedestrian image on a full-color LED dot matrix display screen to warn passing vehicles. The laser beam sensor has high precision and a low false alarm rate, and can operate stably under complex weather conditions. The ultrasonic ranging sensor is arranged at the intersection to measure the distance between the vehicle and the intersection. When the distance is less than a set threshold, the control device displays the vehicle image on the vehicle display screen to alert pedestrians to the approaching vehicle. The ultrasonic ranging sensor has high-precision distance measurement capabilities and can accurately determine the approach of vehicles.

[0007] Preferably, the network-connected surveillance camera is used for real-time monitoring of traffic conditions at intersections, providing on-site images to traffic management departments, and enabling remote monitoring via the network. The surveillance camera features high-definition image quality, night vision, and a wide dynamic range, ensuring clear monitoring images under various lighting conditions. The control circuit board integrates a microprocessor with data processing, signal conversion, and logic control functions, enabling precise control of the warning device's actions based on information from the detection device. The microprocessor is a high-performance embedded processor with powerful data processing capabilities and low power consumption.

[0008] Preferably, the power management circuit connects the solar panel and mains power, enabling switching between solar power and mains power to ensure stable system operation and energy saving.

[0009] Preferably, it also includes an environmental sensing module for real-time monitoring of environmental parameters at the intersection, such as light intensity, temperature, and humidity, and automatically adjusting the operating parameters of the equipment according to environmental changes. The environmental sensing module uses high-precision sensors to ensure the accuracy of the monitoring data.

[0010] Preferably, it also includes a data communication module for interacting with the traffic management department's server, uploading intersection detection data and system operating status in real time, and receiving remote control commands.

[0011] Preferably, it also includes a data communication module for interacting with the traffic management department's server, uploading intersection detection data and system operating status in real time, and receiving remote control commands. The data communication module supports multiple communication protocols to ensure the stability and security of data transmission.

[0012] Preferably, the system also includes an emergency lighting module and a voice prompt module. The emergency lighting module automatically turns on at night or in low light conditions to improve the visibility of intersections and further ensure traffic safety. The emergency lighting module uses high-brightness LED beads and features fast start-up and long lifespan. The voice prompt module can issue a voice prompt when it detects pedestrians or vehicles approaching, reminding passing vehicles and pedestrians to pay attention to safety. The voice prompt module has multiple voice broadcast functions and can provide customized prompts according to different scenarios.

[0013] (III) Beneficial Effects This invention provides a traffic road ghost peek warning light, which has the following beneficial effects: 1. This invention achieves comprehensive, high-precision detection of pedestrians and vehicles at intersections through the coordinated operation of a laser beam sensor and an ultrasonic ranging sensor. The laser beam sensor can operate stably under complex weather conditions, promptly capturing the crossing behavior of pedestrians or non-motorized vehicles; the ultrasonic ranging sensor accurately measures the distance between vehicles and the intersection, providing accurate data to alert pedestrians.

[0014] 2. This invention constructs a complete two-way early warning system. When pedestrians or non-motorized vehicles approach an intersection, the LED light strip and full-color LED dot matrix display screen will light up in time and display the pedestrian image, providing a clear and intuitive visual warning to passing vehicles; while when vehicles approach the intersection, the vehicle display screen will display the vehicle image, reminding pedestrians to avoid the intersection. This two-way early warning mechanism effectively prevents traffic accidents caused by the "ghost pedestrian" phenomenon and significantly improves the safety of intersections. At the same time, the system also has an environmental perception function, which can automatically adjust the operating parameters of the equipment according to environmental changes, ensuring that it can play the best warning role under different environmental conditions, further enhancing the adaptability and practicality of the equipment.

[0015] 3. This invention demonstrates significant advantages in energy conservation, environmental protection, and intelligent management. The power management circuit connects the solar panel and mains power, prioritizing solar power and automatically switching to mains power when sunlight is insufficient. This ensures stable system operation, achieves energy conservation and environmental protection, and reduces operating costs. Attached Figure Description

[0016] Figure 1 This is the circuit schematic diagram of the present invention. Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1

[0019] As shown in Figure 1, this embodiment of the invention provides a traffic road ghost peep warning light, the working process of which is as follows: Detection Phase: Four sets of laser beam sensors on both sides of the intersection monitor the crossing behavior of pedestrians and non-motorized vehicles in real time. Once an object is detected obstructing the laser beam, a signal change is immediately triggered and sent to the control device. Simultaneously, ultrasonic ranging sensors continuously measure the distance between vehicles and the intersection; when the distance is less than a set threshold, a vehicle approach signal is transmitted to the control device. Networked surveillance cameras provide real-time monitoring of the intersection's traffic conditions, offering live video feeds to traffic management departments.

[0020] Data processing and decision-making stage: The high-performance embedded microprocessor integrated into the control circuit board rapidly acquires various signals from the detection device. After data processing and logical judgment, the microprocessor determines the necessary warning action. For example, based on the trigger signal from the laser beam sensor and the distance data from the ultrasonic ranging sensor, it determines whether a pedestrian is about to cross the intersection or a vehicle is about to enter the danger zone of the intersection.

[0021] Warning Phase: Following microprocessor instructions, the LED light strip illuminates at the corresponding height, creating a striking visual warning; the full-color LED dot matrix display shows pedestrian images, alerting passing vehicles to give way; the vehicle display shows vehicle images, reminding pedestrians to be aware of oncoming vehicles. Simultaneously, the voice prompt module issues corresponding voice prompts based on different scenarios, such as "Pedestrians are about to cross, please slow down" or "Vehicles are about to cross, please give way," further enhancing the warning effect.

[0022] Environmental Adaptation Phase: The environmental sensing module monitors environmental parameters at the intersection in real time, such as light intensity, temperature, and humidity. Based on environmental changes, the control device automatically adjusts the equipment's operating parameters. For example, it increases the brightness of LED light strips and displays when light intensity is low, and provides temperature compensation and protection for critical components in high or low temperature environments, ensuring reliable equipment operation and optimal warning effects.

[0023] Energy-saving and remote management phase: The power management circuit prioritizes solar power based on lighting conditions and switches to mains power when necessary to achieve energy-saving operation. The data communication module uploads intersection detection data and system operating status to the traffic management department's server in real time, while also receiving remote control commands, such as remotely adjusting parameters like detection sensitivity and warning volume, to achieve remote intelligent management of warning lights.

[0024] This embodiment has performed excellently in practical applications, effectively reducing the frequency of traffic accidents at intersections, improving the safety and traffic efficiency of intersections, and has been unanimously recognized by traffic management departments and the general public.

[0025] Example 2

[0026] Based on Example 1, this example further optimizes the following aspects: The addition of six laser beam sensors expands the detection coverage, enabling more accurate detection of pedestrians and non-motorized vehicles at different heights and positions, including adults, children, and pets. This effectively avoids blind spots and further improves the comprehensiveness and reliability of the detection. Optimizing the placement and angle of the ultrasonic ranging sensors improves the accuracy of vehicle distance measurements, providing more accurate data for pedestrian alerts.

[0027] Full-color LED dot matrix displays and vehicle displays use higher resolution and brighter LED beads, which can display the image details of pedestrians and vehicles more clearly, such as pedestrians' movements and postures, vehicle types, etc., ensuring that passing vehicles and pedestrians can clearly receive warning information at greater distances and under more complex lighting conditions, providing traffic participants with more time to react and effectively reducing the risk of accidents.

[0028] The system enhances its intelligent linkage with traffic signal systems, automatically adjusting warning methods and content based on different traffic signal states. For example, when the red light is on, it emphasizes reminding pedestrians to wait and not to jaywalk; when the green light is on, it reminds vehicles to yield to pedestrians crossing the intersection. Simultaneously, it achieves deep data interaction with the intelligent transportation platform. Besides uploading basic intersection detection data, it can also receive and publish real-time traffic information such as congestion conditions and traffic accident warnings for surrounding road sections, providing traffic participants with more comprehensive travel guidance, helping them plan their routes rationally, avoid entering congested areas, and improve the overall operational efficiency of the city's transportation system.

[0029] Through the above optimizations and upgrades, this embodiment has significantly improved in terms of detection accuracy, warning effect, and intelligent linkage, further enhancing the application value and safety benefits of the invention in actual traffic scenarios and providing stronger technical support for urban traffic safety management.

[0030] In summary, the present invention provides a traffic road ghost protrusion warning light, which, through its innovative technical solution and multi-dimensional optimized design, has significant advantages in improving the safety, traffic efficiency, and intelligent management level of traffic intersections. It effectively solves many problems in the existing technology, possesses high creativity and practicality, and has broad application prospects and market value.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
