1. A network interconnection device in a remote monitoring system including one or a plurality of sensor equipped communication terminals, the network interconnection device configured to communicate with the sensor equipped communication terminal through a first network, and a monitoring center configured to communicate with the network interconnection device through a second network, the network interconnection device comprising:

  • a receiving unit configured to receive measurement data measured at the sensor equipped communication terminal;

    a determining unit configured to sort the received measurement data into first data to be sent in priority over other data and second data not necessarily to be sent in priority over other data;

    a first data accumulating unit configured to accumulate the first data;

    a second data accumulating unit configured to accumulate the second data;

    a transmission buffer configured to store the first data in priority in sending the first data accumulated in the first data accumulating unit and the second data accumulated in the second data accumulating unit to the second network;

    a transmitting unit configured to sequentially read the first data and the second data stored in the transmission buffer and send the first data and the second data to the second network; and

    a transmission control unit configured to dynamically control an inlet rate in causing the first data accumulated in the first data accumulating unit and the second data accumulated in the second data accumulating unit to come in the transmission buffer based on a communication rate of the second network.
