Summary: | The utility model discloses an intelligent controller with a GSM SMS function, and belongs to low-voltage distribution protective devices. The intelligent controller with the GSM SMS function comprises a microprocessor circuit. An A phase instrument transformer, a B phase instrument transformer, a C phase instrument transformer and an N phase instrument transformer are connected with the microprocessor circuit (1) respectively through an A phase channel signal conditioning circuit, a B phase channel signal conditioning circuit, a C phase channel signal conditioning circuit and an N phase channel signal conditioning circuit correspondingly. The microprocessor circuit is connected with a tripping drive control circuit (5), a memory circuit (6), a system clock circuit (7), a keyboard circuit (9), a grounding channel signal conditioning circuit (12) and a display circuit (10) respectively. A quick-saturated power circuit (11) and an auxiliary power circuit (8) supply power to all the circuits respectively; and a |
