測量參數 : 路面狀況(乾、濕、冰、雪、大量積水)、路面溫度、環境溫度、水膜高度(高達6mm)、露點溫度、相對濕度、含冰比例、摩擦係數(需計算)

MARWIS is the first road and runway weather sensor detecting road conditions, temperatures, friction and other parameters mobile and in real time from driving vehicles.

The mobile road weather sensor MARWIS turns vehicles into driving weather stations by detecting several critical road and runway weather parameters. It can be installed on vehicles with a distance of 1 - 2m above the surface and delivers information about temperatures, waterfilm heights, dew points, road conditions (dry, moist, wet, snow, ice), ice percentages, rel. humidity and friction with a frequency of up to 100 times per second and a max. output rate of 10 Hz. It serves as an important decision support with regard to preventive gritting. Due to the open interface protocols, MARWIS can be easily integrated into existing winter maintenance monitoring networks. Similarly, the mobile road sensor can communicate directly with the control system on gritting vehicles. The measurement data output supports the protocol UMB binary.

Parameters measured: Road condition (dry, moist, wet, ice, snow, slush, chemically wet), road surface temperature, ambient temperature, water film height up to 6mm, dew point temperature, relative humidity, ice percentage, friction (calculated)
