Online flaw detection monitoring system and method for steel wire rope, and multi-rope friction hoisting system for use in mining

An online flaw detection monitoring system and method for a steel wire rope (60), and a multi-rope friction hoisting system for use in mining. The system comprises: a flaw detection sensor (10), a communication module (20) and a computing and processing apparatus (30), wherein the flaw detection sensor (10) is arranged around a steel wire rope (60) to be detected and is used for collecting a flaw signal of the steel wire rope (60) in real time; the communication module (20) is used for converting the flaw signal of the steel wire rope (60) and transmitting same to the computing and processing apparatus (30); and the computing and processing apparatus (30) is used for extracting a fault characteristic value from the converted flaw signal and searching a pre-set fault characteristic library for a steel wire rope (60) fault category corresponding to the fault characteristic value. By means of converting a detected flaw signal of the steel wire rope (60) and extracting a fault characteristic value, and searching a pre-set fault characteristic library for a steel wire rope (60) fault category corresponding to the fault characteristic value, the type of damage to the steel wire rope (60) can be accurately determined at the same time as flaw detection is carried out on the steel wire rope (60), thereby facilitating operating personnel in carrying out a timely check and maintenance on a fault.
