Data Acquisition and Transmission Device

The device is intended for acquisition, processing, storage of data from meters and transfer of information via information channels to the upper level in automated systems for comprehensive utility metering. It is installed as a part of a three phase smart electronic meter and functions together with it.

An important function of the device is time measuring and clock synchronization on the metering devices in automated systems for comprehensive utility metering.

Description

Features:

  • 2 GPRS/LTE modules, micro-USB, Wi-Fi module;
  • Provides event log storage and information transfer on request;
  • Multilevel protection against unauthorized access: mechanical seals, an eight-digit password for access, encryption of information during its transmission through the interfaces of the lower and upper levels of the device;
  • Linux based operating system;
  • Storage depth: 6144 readings per interval.
    •  

    Data acquisition performed:

    • active consumed and generated power;
    • reactive consumed generated power;
    • general power;
    • amount of tariff storages (operated/all) for active consumed/generated power;
    • tariff accumulations according to each tariff for active consumed/generated;
    • voltage (average value during the integration period);
    • current intensity (average value during the integration period);
    • frequency (average value during the integration period);
    • event log.

    Sends information to the upper level about the following events:

    • overlimit of active power;
    • current threshold crossing along neutral channel;
    • consumer electrical installation deviation;
    • network frequency deviation;
    • voltage state – overlimit; failure;
    • power overlimit 1/2/3;
    • critical time deviation or forbidden time unsynchronization;
    • low consumption for a long time;
    • the device is open – terminal block /housing;
    • magnet or reverse magnet interference (for meters including magnetic field sensors); 
    • radio field interference (for meters including radio-frequency electromagnetic field sensors);
    • password blocking;
    • low battery;
    • data transfer via communication channel during the emergence the event was performed;
    • flag of requirement of schedule group change;
    • reason for the latest unscheduled automatic start.
