Road monitoring systems

Netsens manufactures sensors and systems for numerous road traffic applications, including RWISs and land-to-vehicle and toll collection, like  Telepass®.

ROAD MONITORING SYSTEMS

For 15 years Netsens has produced and installed advanced road traffic systems, from RWIS with state-of-the-art meteorological sensors and measurement of road surface condition, used particularly for motor road and highways winter management, to communication systems using OBUs (On-Board Units) for toll payments collection travel times monitoring.

Netsens range of advanced technology products includes:
– PWSense backward scattering laser sensor for visibility and precipitation
– RoadSense multi-parameter road surface sensor
Linux-based CPU with MeteoMod industrial data logger function.

 

APPLICAZIONS

ROAD WEATHER MONITORING

Netsens systems for road weather monitoring use advanced environmental sensors, many of which are produced by the company. These include:
• Meteorological sensors (temperature and air humidity, wind direction and speed, pressure)
• Precipitation sensors (type and intensity of precipitation)
• Road sensors (passive and multi-parameter)
• Visibility sensors
Netsens can supply “turnkey” solutions with data collection and transmission system (data logger), also suitable for sites with no access to the electricity grid, in which all systems (sensors, data collection, transmission) use only a solar power kit with a backup battery.

TECHNICAL CHARACTERISTICS OF mETEOMODACQUISITION UNIT

The MeteoMod CPU data logger, designed and produced by Netsens, embeds all the functions of a small workstation: Linux operating system, expandable data acquisition peripherals, non-volatile solid state memory, hardware-level operation supervision. TCP/IP communication to the central system takes place via LAN and external modem/router. The configuration and data visualization takes place via an advanced interface on the Webserver, which allows all the main maintenance and diagnostic operations to be carried out locally and remotely.

The open architecture allows you to implement and customize many features required today for this application including:
management of communication processes with sensors
• data pre-processing and alarm generation software
• data formatting
• operator interface management
• data processing algorithms (generation of averages and statistics)
automatic or scheduled update of software packages

The system architecture also enables to forward the data received from the stations to other monitoring and management platforms, through the implementation of appropriate machine-to-machine data exchange protocols (eg XML).
