ClairSRS Solar Mag is a solar-powered smart road stud with a built-in geomagnetic sensor, capable of detecting the speed and movement of passing vehicles and triggering corresponding response mechanisms. It utilizes various light colors and flashing frequencies to provide different signaling functions such as warnings, guidance, or traffic diversion. Solar Mag features an innovative chain communication network, where each stud collects vehicle detection data from nearby studs and makes decisions on the response strategy. This design resolves network congestion issues seen in traditional communication methods, ensuring seamless warning light synchronization even for high-speed vehicles. Solar Mag is ideal for scenarios such as foggy highways or sharp curves where dynamic vehicle-following effects are needed.
ClairSRS Solar is a model in the solar-powered smart road stud series that does not include a geomagnetic sensor. It can achieve the desired lighting effects through time-based control or by receiving external commands for individual or grouped stud control. The Solar model uses LoRa technology to build a star network, with one LoRa gateway covering up to a 1.5 km radius, and the number of connected nodes is unlimited. This model is suitable for scenarios where vehicle-following effects are not required and for solar-powered applications, such as typical road delineation functions. When integrated with video or radar detectors, it can also trigger flashing light alerts for high-speed anomaly events.
Key Features
Solar Power Supply: Powered by solar energy, the device is equipped with an 8000mAh high-capacity lithium iron phosphate battery, along with an efficient energy management system. This ensures up to 720 hours of continuous operation even in the absence of sunlight.
Geomagnetic Sensing: The road stud is equipped with a built-in geomagnetic sensor that detects the approach and departure of vehicles. It collects various traffic parameters such as vehicle speed, queue length, and occupancy, and can detect vehicle stops or reverse movements. The system triggers corresponding responses using different light colors and flashing frequencies, enabling functions such as warnings, guidance, or traffic diversion.
Ultra-bright LED Beads: The device features ultra-bright LED lights that can actively emit light in low visibility conditions or at night, enhancing road visibility and driving safety. Even during the day, the LEDs provide effective road guidance and information dissemination.
LED Control Mode: The warning mode of the LED lights includes control over position, brightness, duty cycle, and frequency.
Temperature Management: Equipped with a built-in temperature sensor, the device automatically adjusts the current to prevent overheating. This helps maintain the stability of the LEDs, extends their lifespan, and ensures they consistently output high brightness in various environmental conditions.
Flush Ground Installation: With a patented dual-stage light refraction design, the LED beads of the road stud do not need to protrude above the road surface while still achieving excellent long-distance visibility. The road stud remains flush with the ground, ensuring it does not interfere with snow plows or other road maintenance equipment.
Chain Communication: Each road stud gathers vehicle detection data from nearby studs and makes decisions on response strategies. This distributed decision-making and low-latency communication system eliminates network congestion issues typical of traditional communication methods, ensuring seamless light warning and vehicle-following effects even at high speeds.
Wide-Temperature and Pressure-Resistant Housing: Made of reinforced PC material, the housing can withstand operating temperatures ranging from -45°C to 85°C and pressure up to 26.5 tons.
NFC Programming and Remote Firmware Upgrades: NFC programming allows for configuration of location information, device reboot, firmware updates, parameter adjustments, mode switching, and information retrieval.
Application Scenarios
Curve Warning: In situations such as small-radius curves or poor-visibility road sections, the system can manage scenarios like single-vehicle travel, oncoming traffic, and roadside parking.
Functionality: 1. For Vehicles Ahead: Yellow (or white) lights illuminate in front of the vehicle. 2. For Vehicles Behind: Red lights are displayed at the rear. 3. For Oncoming or Rear Traffic: The centerline and edge lines also adjust accordingly to enhance visibility and safety.
Fog Zone Driving Alerts & Main Road Section Visibility Alerts: In foggy areas, highways during fog, curves, and other poor visibility sections, as well as at night, the system provides lane line delineation, single-vehicle sliding guidance, and multi-vehicle following alerts. Yellow (or white) lights illuminate within a specified range in front of the vehicle, while red lights illuminate within a specified range behind the vehicle, moving with the vehicle.
Emergency lane parking alerts on main road sections: When a vehicle is parked in the emergency lane on a highway, the system activates emergency lane parking alerts. Red lights are turned on within a certain range behind the parked vehicle to warn following drivers.
Merging zone collision alerts and diverting zone abnormal behavior alerts: Before a vehicle merges onto the main road from an on-ramp, if there are vehicles passing in the rightmost lane of the main road, yellow lights are activated in front of both the on-ramp and main road vehicles to provide real-time warnings. If there is a collision risk, red lights are turned on. When a vehicle exhibits abnormal behavior such as slowing down, stopping, or reversing due to missing a diversion ramp, the system provides alerts to following vehicles on the main road by turning on red lights within a certain range behind the vehicle.
