Description
Claims (4)
- 링형상의 통신네트워크(9)상을 주회하는 제어데이터를 수신한 다음 재수신할 때까지의 대기시간을 통신네트워크의 상태에 따라 결정하는 대기시간결정수단(5)과, 이 대기시간결정수단(5)에 의해 결정된 대기시간을 유지하는 대기시간유지수단(3) 및, 상기 제어데이터의 수신에 의해 시간을 계수해서 상기 대기시간유지수단에 유지되어 있는 대기시간경과후에 있어서도 제어데이터를 재수신할 수 없는 경우 이상신호를 출력하는 시간계산수단(1)으로 구성된 것을 특징으로 하는 통신제어장치.
- 제1항에 있어서, 상기 대기시간결정수단은 통신네트워크상에 배치되는 각 통신제어장치로부터 송출되는 존재통지신호(AMP, SMP)를 수신하고, 이 존재통지신호(AMP, SMP)로부터 통신네트워크상에 배치되는 통신제어장치의 수를 산출하며, 산출된 통신제어장치의 수로부터 상기 통신네트워크에 필요로 되는 최소한 대기시간을 계산하도록 된 것을 특징으로 하는 통신제어장치.
- 제1항에 있어서, 상기 대기시간결정수단은 통신제어장치의 수를 임의로 입력하는 존재국수입력수단(11)과, 이 존재국수입력수단(11)에 의해 입력된 통신제어장치의 수로부터 이 통신네트워크에 필요로 되는 최소한의 대기시간을 계산하는 대기시간계산수단(5)으로 이루어진 것을 특징으로 하는 통신제어장치.
- 제1항에 있어서, 상기 대기시간결정수단은 통신네트워크상에 배치되는 각 통신제어장치로부터 송출되는 존재통지신호(AMP, SMP)를 수신하고, 이 존재통지신호(AMP, SMP)로부터 통시너네트워크상에 배치되는 통신제어장치의 수를 산출하며, 산출된 통신제어장치의 수로부터 대기시간을 계산하는 제1대기시간계산수단(5a)과, 통신제어장치의 수를 임의로 입력하는 존재국수입력수단(11), 이 존재국수입력수단(11)에 의해 입력된 통신제어장치의 수로부터 대기시간을 계산하는 제2대기시간계산수단(5b) 및, 상기 제1대기시간계산수단(5a)에 의해 계산된 대기시간과 상기 제2대기시간계산수단에 의해 계산된 대기시간을 비교해서 긴 쪽의 대기시간을 상기 통신네트워크에 필요로 되는 최소한의 대기시간으로 하는 대기시간 비교수단(13)으로 이루어진 것을 특징으로 하는 통신제어장치.
