The invention provides a discharging platform early warning system and method based on an anchoring part. The system comprises an anchoring part (including a main body of the anchoring part (including a base plate and two side plates), a connecting piece and a hollow pin) and an early warning device (including a microprocessor, a strain sensor and an alarm), wherein the hollow pin penetrates through two first through holes in two side plates; a second through hole is formed in the base plate; the base plate is fixed on the wall of a working layer through the second through hole and the connecting piece; the center of the second through hole is located on the line under the tensional state of a steel wire rope; the strain sensor is arranged on the inner wall of the hollow pin, and is located on the line under the tensional state of the steel wire rope; the strain can be obtained and sent to the microprocessor when the gravity generated from the added material on the discharging platform enables the hollow pin to be deformed by tensioning the steel wire rope; the microprocessor determines whether the strain is more than or equal to the preset threshold according to the obtained strain of the hollow pin; and if the strain is more than or equal to the preset threshold, the alarm is controlled to raise the alarm. The discharging platform early warning system and method based on an anchoring part can monitor whether the bearing of the discharging platform overloads in real time, and can timely perform early warning and improve the safety.
