Method and system for intelligently calibrating length of broken cloth

The invention provides a method and system for intelligently calibrating the length of a broken cloth, and the method comprises the following steps: recognizing the broken material information of a material, and transmitting the broken material information to a PLC (Programmable Logic Controller), the broken material information comprising the broken cloth meter number; the PLC controls cloth length calibration equipment according to the material breaking information, and the cloth breaking length position is calibrated on the material breaking table through the cloth length calibration equipment; and breaking the cloth according to the calibrated cloth breaking length position. Through data interaction between upper computer software and a lower computer PLC, the function and operation of intelligently calibrating the cloth breaking length are achieved, data such as the cloth breaking length is directly transmitted to the controller by recognizing an information carrier on a material, cloth breaking equipmen
