The invention relates to the technical field of automobile braking, in particular to a commercial vehicle EMB emergency braking redundant power source and monitoring system, the positive electrode of a power battery pack is connected with a first fuse and a second fuse in parallel, the first fuse is connected with a DCAC module and used for converting direct current into three-phase power and transmitting the three-phase power to a braking motor, and the second fuse is connected with a voltage reduction DCAC module and used for converting the three-phase power into three-phase power and transmitting the three-phase power to a braking motor. A step-down DCAC module is connected between the power battery pack and the low-voltage storage battery and used for reducing the direct-current high voltage and then transmitting the direct-current high voltage to the low-voltage storage battery, a step-up DCAC module is connected between the step-down DCAC module and the low-voltage storage battery, and when the power battery pack fails, the step-down DCAC module is used for transmitting electric energy of the low-voltage storage battery to the DCAC module, converting direct current into alternating current The standby power supply is a low-voltage storage battery sensor of the vehicle, and an additional power supply is not needed; when the power battery pack breaks down, an alarm signal can be sent to an instrument, the instrument can prompt a driver after receiving the alarm signal, and the intelligence of the whole vehicle is improved; and a standby power supply is constructed to supply power to the brake motor, so that the driving safety of the whole vehicle is improved.
