Abstract

PURPOSE:To improve the excess degree of communication and processing and to immediately transfer an important alarm. CONSTITUTION:When a monitored device 19 outputs an alarm signal 14, the sorting processing part 11 of respective first alarm cllecting devices 20 sort them into transfer alarm signals 17 and accumulating alarm signals 18. After receiving an accumulating signal 18 from the processing signal 11, a transfer part 12 immediately transfers it to a second alarm processor 21 as an output alarm signal 15. On the other hand, at the time of receiving the accumulating alarm signal 18 from the processing part 11, an accumulating part 13 accumulates it. In the second alarm collecting device 21, a collecting part 22 receives the output alarm signal 15 from the first alarm collecting device 20 to execute necessary processing, detects the excess degree of processing on the other hand and transmits an alarm transfer demand signal 16 at the time of presence of excess. When the transfer part 12 receives the signal, the accumulating alarm signal 18 is fetched from the accumulating part 13 and is transferred to the collecting processing part 22 of the second alarm collecting device 21 as the output alarm signal 15.
