Features

  • Performs advanced algorithms based on sensor measurements
  • Storage for all observations, configurations, serial numbers, and maintenance history
  • Reliable in harsh environments
  • Industry-proven components that guarantee reliability and extend the life span
  • Built-in web user interface
  • GPS receiver for accurate time synchronization
  • Reliable internal communications from Ethernet architecture Effective data management DMU703 manages data flow, performs algorithm calculations, stores observation data, and provides a web- based user interface for viewing data remotely and for controlling the system. In addition to managing realtime data flow, DMU703 also handles sensor calibration data, maintenance activities, and configurations, including serial numbers and software versions. To have this information available both locally and remotely helps in troubleshooting and maintaining the weather station. DMU703 contains a local database which greatly improves data reliability by storing observation data. The data is not lost even if the external communication network is down for a long period of time. Advanced algorithms DMU703 contains the algorithms that make RWS200 more than a collection of road weather sensors. The algorithms process the observation data from the atmospheric and road weather sensors and provide accurate data to support decision making. Web user interface A web user interface provides direct access to the weather station. The user interface is available locally and remotely and it is used for station setup and maintenance, as well as for viewing observation data and reports. Looking ahead A DMU703 unit purchased today can be updated either remotely or in the field to support new features and functions as they are designed by Vaisala. Vaisala Data Management Unit DMU703 is specifically designed and built to be the brains of Vaisala Road Weather Station RWS200. DMU703 handles the storage, analysis, and reporting of observation data.
