Claims (3)
- 複数個所のガス漏れを検知するガス漏れ検知システムであって、
制御装置と、
前記制御装置に対して直列に接続されている複数のガス計測器と、
を備えており、
複数の前記ガス計測器のそれぞれは、
前記制御装置から遠い側に接続されている前記ガス計測器からガス濃度と識別子を受信し、
受信したガス濃度と自己が計測したガス濃度を比較し、
受信したガス濃度が高い場合は受信したガス濃度と受信した識別子を前記制御装置に近い側の前記ガス計測器へ送り、
自己が計測したガス濃度が高い場合は自己が計測したガス濃度と自己の識別子を前記制御装置に近い側の前記ガス計測器へ送る、ガス漏れ検知システム。 - 複数の前記ガス計測器のそれぞれは、
前記制御装置から遠い側に接続されている前記ガス計測器から上側ガス濃度と下側ガス濃度と識別子を受信し、
受信した上側ガス濃度と、自己が計測したガス濃度を比較し、
受信した上側ガス濃度が高い場合は受信した上側ガス濃度と受信した識別子を前記制御装置に近い側の前記ガス計測器へ送り、
自己が計測したガス濃度が高い場合は自己が計測したガス濃度を新たな上側ガス濃度とするとともに自己の識別子を前記制御装置に近い側の前記ガス計測器へ送り、
受信した下側ガス濃度と、自己が計測したガス濃度を比較し、
受信した下側ガス濃度が低い場合は受信した下側ガス濃度を前記制御装置に近い側の前記ガス計測器へ送り、
自己が計測したガス濃度が低い場合は自己が計測したガス濃度を新たな下側ガス濃度として前記制御装置に近い側の前記ガス計測器へ送る、請求項1に記載のガス漏れ検知システム。 - 直列接続の末端に接続されているガス計測器を除く残りの計測器は、前記制御装置から遠い側の前記ガス計測器からガス濃度を受信できなかった場合には、異常発生を示す予め定められたガス濃度を前記制御装置に近い側の前記ガス計測器へ送信する、請求項1または2に記載のガス漏れ検知システム。
