The invention discloses a safety early-warning system of a carriage. The system comprises a single-chip microcomputer, and a weighing module, a supersonic range finding module, a motor driving module, an LCD screen and a power supply module connected with the single-chip microcomputer; and the single-chip microcomputer module generates different pulse width modulation signals to control the motor driving module according to distance information input from the supersonic range finding module. According to the safety early-warning system of the carriage, the weighing function is combined with the range finding function, the single-chip microcomputer realizes driving control, the weighing module can accurately weigh the total load carrying weight, the supersonic range finding module measures the distance between the carriage and an obstacle in front, and the LCD screen displays different operation states and measuring results; and the system is stable in operation and high in reliability.
