VMS / DMS is an important equipment for monitoring and controlling system in both freeway and arterial road applications. These signs give the traffic management center a powerful tool to improve traffic flow on busy expressways by displaying varied message. 

DARMON now holds over 35% market share of VMS/DMS in China, by completing various VMS/DMS projects in 250+ highways in China and overseas. As everyday in the past 17 years, we subject our products to 17 separate assessments and 40 different functionality tests, which are all carried out in our in-house central laboratory.

Circle Mandatory Sign, Color Inversion and Cluster 

in single color, dual color and full color.




Physical Features:

● A louvered-face design to reduce glare and enhance contrast ratio on LED Module. The legibility is all it concerns.
● The state-of-the-art cabinet design enables to separate the whole sign into pieces for convenience in transportation and installation.
● The modular design allows the sign to be built in various size.
● LED module is sealed twice with the top-class brand silicon-gel to ensure good elasticity, aging-resistance, water-proof, dust-proof and UV- resistance. And the module is easy to remove for replacement.
● The cabinet has both forced air ventilation and natural heat-dissipation system. Its structure results internal air convection, to balance the ambience temperature in cabinet.
● All components, including the LED modules, power supplies, controlling boards and ventilation systems are easily accessed by opening the double-layer weather-resistant rear doors.
● The smart wiring of advanced power system and controlling system decreases EMC problems, and it offers convenience to maintenance people from customer’s company.
● Complies with EN12966.

 

Controlling Features:

● System control using through Industrial PC, with inside a wide range of standard pictograms and messages stored in a library. Ability to display customized messages.
● The full matrix VMS/DMS enable to show MUTCD characters, logos, and other graphics. Nominal character sizes include 9 inches, 12 inches, and 20 inches.
● All models are available with amber, red/green or full color LED technology with either 30 degree viewing angles or others.
● The experienced R&D team has high flexibilty and ability to adapt to any existing communication protocol, including NTCIP.
● The diagnostic system simplifies maintenance by monitoring and reporting on the status of the LED modules, power systems, ventilation components, and more.
