Abstract:
1. A current monitoring system, comprising: at least one current monitoring unit, each of the at least one current monitoring unit comprising a current detection resistor, an amplifier, and a comparator; and an indication device electronically connected to an output terminal of the comparator of each of the at least one current monitoring unit; wherein the current detection resistor is electronically connected between a non-inverting terminal and an inverting terminal of the amplifier, a node between the current detection resistor and the non-inverting terminal of the amplifier is electronically connected to a current terminal of a motherboard, one of a non-inverting terminal and an inverting terminal of the comparator is electronically connected to an output terminal of the amplifier, the other one of the non-inverting terminal and the inverting terminal of the comparator is electronically connected to a reference power supply; the comparator compares an output voltage of the amplifier with an output voltage of the reference power supply, to determine whether a current output from the corresponding current terminal is abnormal; the indication device encodes and displays a determination of the comparator and alarms according to the determination; and wherein the indication device comprises a display unit comprising a connector, an LED numerical display, and an encoder connecting the connector to the LED numerical display, the connector is electronically connected to the output terminal of the comparator of each current detection unit, the encoder receives signals from the output terminal of the comparator, and encodes the signals into codes, the LED numerical display receives the codes and display the codes, to denote whether the current of the current terminal is abnormal.
