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…
LUFFT – Mobile Advanced Road Weather Information Sensor (MARWIS)
Description
MARWIS – Mobile Advanced Road Weather Information Sensor
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.
- 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)
- Optical LED transmitters, photo receivers, pyrometer, infrared
- Mobile, plug and play, 100 measurements per second with max. output rate of 10Hz, multifunctional, real time thermal mapping, wireless data transfer
- Bluetooth, RS485, CAN-Bus
- 8900.U03, 8900.U04
Advantages of the mobile road and weather sensor MARWIS:
- Easy data transfer via Bluetooth, RS485 or CAN-Bus
- Dynamic mobile data in real time and 100 times per second and a max. output rate of 10Hz.
- Multifunctionality
- Measurements both on the ground and in the ambient air
- Easy to install and to clean
- Free MARWIS app for calibration, data view as well as transfer available on Google Play and iTunes
- One or two meter version for different vehicle types
Examples of use of the mobile road and weather sensor MARWIS:
- Decision support for winter maintenance operators on roads, motorways, highways (municipalities, federal states and provinces)
- Decision support for the de-icing of runways (higher efficiency)
- As important part of the IDS (Ice Detection System) in form of a RCC (Runway Condition Code), water film height (aqua-planning risk) and friction detector on airports (digital alternative to mechanic grip testers)
- For smart city applications
- For weather data collection and weather forecast model improvements
