Variable Speed Limit Sign (VSLS)

Standard GB/T 23828-2009 ,
Intelligent System,
Strong Weather Resistance

Variable Speed Limit Sign (VSLS) is mainly used to display the speed limit values, and the speed limit values can be changed. VSLS can assist traffic managers in scientific and efficient traffic management, and dynamically adjust the speed limit value according to the actual conditions on the road. Besides Comsight VSLS has a full dot matrix design and is therefore a multi-purpose transportation display.

SAFE SYSTEM

Reliable

— High-quality and high-brightness LED, high-efficiency and high-temperature resistant, Meanwell power supply, industrial-grade mainboards and components. Derating use on parameters and leaving enough margin to ensure long-term stability and reliability.
— Use AkzoNobel`s powder coating for strong weather resistance and more stability
— With N+1 power supply backup. When the power supply fails, the backup power supply will seamlessly take over and notify the control center.
— Thermal management detail:
1)use high-brightness LED, high-efficiency power supplies and low-voltage supply to reduce the heat productivity inside the cabinet
2)use light-colored cabinets with double-layer design to reduce the solar radiation impact
3) use an optimized design of fan-forced cooling system to accelerate the heat dissipation inside the cabinet.
4)These comprehensive measures will reduce the temperature rise of the VMS, improve the reliability, and reduce the light decay of the LED.

Intelligent

— Intelligent Full Monitoring Capability
Detect LED failures, monitor door status, power supply, fan, dust filter, internal temperature, ambient temperature, etc., and have a long-term preservation for the log records in the control center database.
— Intelligent Brightness Adjustment Function
Based on the real-time monitoring of ambient brightness, proceed non-linear automatic dimming control (automatic mode).
— Powerful Software for Traffic Information Management
It knows everything about the running status of the VSLS. When the display content is updated, the LED is faulty, or the monitoring status is abnormal, it will feed back to the control center and send SMS to the operator, even if the operator is not at the control center, he can also know the running status of VSLS in time.
— Intelligent Alarm Function
Users can preset the temperature value for the alarm, brightness down, display off and power off. The VSLS will carry out the corresponding actions according to the monitored temperature value.

Safe

SMS warning

Surge protection

VSLS has surge protection, leakage protection and other safety measures

High temperature protection

High temperature protection function: When the VSLS temperature exceeds the set value, it will take the corresponding actions of alarm, brightness down, display off and power off, timely proceed the high temperature protection to ensure the safety for the VSLS and prevent the occurrence of fire.

LED Display Guides

Traffic information management software, with login password protection function, unauthorized person cannot operate the software and VSLS; encrypted communication between the management software and VSLS, illegal software is forbidden to control the VSLS, to ensure the VSLS operation of high security and accuracy.
