Monitoring system and monitoring method

A monitoring system, applied on a shaping machine having a high speed electricity meter, the monitoring system comprising:

• a current obtaining device, communicatively coupled to the high speed electricity meter, wherein the current obtaining device is configured to obtain a plurality of current signals from the high speed electricity meter during operations of the shaping machine and in respond to the shaping machine executes a machining program, the current obtaining device extracts current variation data from the current signals, wherein the machining program corresponds to a piece of the current variation data, and the piece of current variation data comprises a maximum current and an occurring time that the maximum current being recorded;
• and
• an analyzing device, electrically coupled to the current obtaining device, wherein the analyzing device is configured to calculate a gap time, based on the maximum currents and the occurring times respectively corresponding to at least two successive machining programs, wherein in respond to the gap time exceeding a predetermined threshold, the analyzing device generates a warning signal.
