The embodiment of the invention provides an engineering machinery overspeed fault identification method, a storage medium and a processor. The method comprises the following steps: acquiring the current frequency of a motor and the current rotating speed of a winding drum in the process of controlling the hoisting mechanism to accelerate or decelerate; determining the running time required by the motor to run to the current frequency; determining a first current slope coefficient of the motor during acceleration operation or deceleration operation according to the current frequency and the operation time; determining a second current slope coefficient during acceleration operation or deceleration operation of the motor according to the current rotating speed, the motor parameters of the motor and the operation time; according to the first current slope coefficient and the second current slope coefficient, whether the hoisting mechanism has the overspeed fault or not is determined, the overspeed fault of the hoisting mechanism can be judged in the accelerated operation or decelerated operation process of the motor, whether the hoisting mechanism has the overspeed fault or not is determined in time, and the operation safety of engineering machinery is ensured.

    本申请实施例提供一种用于工程机械超速故障的识别方法、存储介质及处理器。方法包括:在控制卷扬机构加速运行或减速运行的过程中,获取电机的当前频率,以及卷筒的当前转速;确定电机运转至当前频率所需的运转时间;根据当前频率和运转时间确定电机加速运行或减速运行时的第一当前斜坡系数;根据当前转速、电机的电机参数以及运转时间确定电机加速运行或减速运行时的第二当前斜坡系数;根据第一当前斜坡系数和第二当前斜坡系数确定卷扬机构是否发生超速故障,能够在电机加速运行或减速运行的过程中对卷扬机构的超速故障进行判断,及时确定卷扬机构是否发生超速故障,确保工程机械运行的安全性。
