Abstract | The invention provides a double-phase electric shock detection and protection device based on signal similarity matching. The device comprises a release, a current sensing device and a double-phase electric shock intelligent identification device, wherein the release is used for cutting off a power supply, and the current sensing device is used for detecting an electric leakage state; and the double-phase electric shock intelligent identification device is used for monitoring whether a double-phase electric shock condition occurs or not, and controlling the release to cut off the power supply when the double-phase electric shock is detected. The double-phase electric shock intelligent identification device obtains current waveforms in a phase line and a zero line through a current induction coil of a current induction device, compares the current waveforms with various current waveform template execution templates pre-stored in a database of the double-phase electric shock intelligent identification device, a |
