The invention discloses an experimental system for detecting a broken wire of a wire rope of a hoist and a detecting method thereof, and the experimental system comprises a bottom plate, a first support device, a second support device, a third support device and a detecting device, wherein the wire rope is sequentially wound around a pair of support wheels on the left side, a left tensioning wheel, a driving wheel, a right tensioning wheel, and a pair of support wheels on the right side and forms a closed loop; the detecting device comprises an excitation device and a detecting component; theexcitation device is arranged on the wire rope; and a Hall sensing array is sequentially connected to a conditioning device and a signal collecting device. The corresponding detecting method denoisesmultiple scale signals by improving the non-local mean denoising method, and uses the particle swarm optimized support vector machine model to quantitatively identify the broken wire. The experimentalsystem for detecting the broken wire of the wire rope of the hoist and the detecting method thereof perform signal acquisition and analysis under different working conditions of wire rope, realize the quantitative identification of broken wire, and have the advantages such as fast detection speed and non-contact.
