The intelligent zebra crossing warning system solution solves the traffic safety problem at night when there are no traffic lights at the zebra crossing at the intersection of urban branch roads, roads with more lanes or safety islands in the middle, urban suburban roads, national and provincial roads and branch roads along the road, and provides a new intelligent and safe travel solution for citizens.
The intelligent zebra crossing warning system solution is mainly used at both ends of the zebra crossing where there are no traffic lights at night or the night lights are changed to flashing yellow lights.
Through laser detection, at the moment when pedestrians enter the zebra crossing, the intelligent zebra crossing warning device projects 28 red laser lines to the pedestrian's calf, forming a red area projection, and emits a sound to remind pedestrians to pay attention to the coming car and pass the zebra crossing as soon as possible.
Motor vehicle drivers can get a red warning and find pedestrian dynamics at a distance in the case of insufficient lighting, inattention or affected sight (opposite vehicles, rain and fog weather, etc.), so as to reduce the occurrence of traffic accidents.
Warning: Sound alerts pedestrians and laser reflections alert drivers.
Fast: high-speed laser detection, wireless transmission signal, 0.2 seconds response speed.
Precision: Intelligent laser ranging sensing, more accurate identification of pedestrians.
Safety: RF seamless link, at the same time open the opposite beam, crossroad pedestrians early warning, driving safety and convenience.
Energy saving: Use GPS timing, standby during the day and work at night to save power.
Guarantee: Intelligent Internet of Things fault alarm.
Waterproof: P67 waterproof design, no fear of wind and rain attack.
Core technology:
The product effect is good, the application is wide, the quality is excellent. Through the actual test, the road using the intelligent zebra crossing warning system can effectively reduce the accident rate of crosswalks and right-turn crosswalks; Significantly improve drivers' recognition of pedestrians in inclement weather and poor visibility at night; Comprehensively enhance the safety awareness of pedestrians crossing crosswalks and the initiative of vehicles to yield pedestrian awareness.
Advanced: Using the world's advanced nanoscale semiconductor laser group, low energy consumption, high safety, with customized optical lenses, the light is eye-catching and harmless.
Stability: The main body of the hardware equipment is made of high-quality materials resistant to impact and corrosion, waterproof and dustproof, beautiful and complete for a long time; The main structure design is rigorous and the layout is reasonable to avoid electromagnetic interference, loose parts, short circuit and high temperature.
Safety: The equipment adopts civil safety laser, the equipment has been tested for long-term waterproof, leak-proof, anti-pressure and anti-lightning, and the circuit system has multiple safety protection to avoid leakage and short circuit.
Network: Built-in intelligent Internet of Things module and wireless communication system to achieve wireless monitoring and regulation of equipment.
Scalability: It can add a variety of functions and connect other devices.
Program composition:
The overall solution includes front-end equipment (intelligent zebra crossing warning device), 4G Internet of Things, cloud control platform (or wired network).
Cloud control platform
Account management, administrator Settings, permission Settings, adding and deleting devices.
View front-end device location, working status, exception alarms, and working data.
Set front-end device parameters: working time, laser lighting duration, brightness, etc.
Business process
In hibernation state, the front-end device stops working and only the network module keeps working. Administrators can view device information and set related Settings on the platform.
When entering the working time set by the platform, the previous section of equipment begins to work, always maintaining pedestrian detection. When a pedestrian enters a zebra crossing, the laser light group begins to project and issue a voice prompt, and when there is no pedestrian, the laser light group turns off.
Enter the shutdown time set by the cloud control platform, and the previous segment of the device enters the sleep state.
