Concentrators AMKR

The AMKR device is a simple microserver designed for regular data collection from electricity meters (AMR system) and then upload to an FTP server for further processing. An additional function is the automatic processing of all collected data into own database, thus ensuring a backup of the data and allows the user to check, view or monitor the collected data in a presentation form (tables, graphs, statuses).

Properties

  • Possibility to configure up to 3 different FTP servers (even outside the LAN);
  • Communication with electricity meters wireless via MESH, wired via RS485, or a combination thereof;
  • User interface - web pages from any web browser (Firefox, Chrome, Opera,…);
  • Standard network device with the ability to connect to the Internet and provide remote access;
  • Applications have their own database of users, i. user accounts to individual applications are independent of each other, and each application uses a different port for access.
