The utility model relates to an integration power failure real -time monitoring system, include the signal acquisition element, communications network, data concentrator and the independent communication power supply network management that connect gradually, signal acquisition line connection signal acquisition element is crossed to the integration power -on, and signal acquisition element passes through the optic fibre tail optical fiber and connects communications network, and communications network passes through the optic fibre tail optical fiber and connects data concentrator, and data concentrator passes through with the independent communication power supply network management of communications network 0 connection, signal acquisition element include CPU module and the 220V power module who is connected with the CPU module respectively, 48V power module, super capacitor or battery, optical fiber communication interface, network interface and isolator, isolator connect collection module, and collection module gathers the power module 0 and the power module 1 of integration power. This system can still guarantee communication transmission equipment and normally work after the integration power break down, is favorable to communication fortune dimension worker to make source the very first time to power failure and manages.
