Rope protection is the protection function of large mineral lifting equipment. At present, most of the iron ore hoist sliding rope protection is the speed difference detection algorithm, and it is able to determine whether or not the hoisting machine system has a sliding rope fault, which can give the automatic emergency stop protection. In this paper, a new sliding rope protection algorithm is proposed. This design works with measuring the pulse offset by comparing the difference between the running pulse value of the roller and the running pulse value of the main control system in real time. It determines whether or not the hoisting device has a sliding rope fault. According to the results of the main control system, making the fault protection action, in order to avoid causing major accidents. And it has been applied to the iron ore hoist.
