Document Type and Number:
Japanese Patent JP2836505
Kind Code:
B2
Abstract:
A data transmitter/receiver of a centralized monitoring station (1) transmits data and received data from each of monitored stations (2-1,2-2). A polling level table (11) stores polling levels calculated from request data level and transmission data level added to transmission data from the monitored stations. A monitored station number table (14) stores the numbers of a monitored station to be polled with a polling level equal to or greater than 2 in one polling cycle. A polling level determining unit (13) determines polling levels to be transmitted to the respective monitored stations based on the contents of the polling level table and the monitored station number table. A data transmitter/ receiver (20-1) of each of the monitored stations transits transmission data level corresponding to the polling level and transmission data with the added request data level to the centralized monitoring station.
