The invention relates to the technical field of overload early warning, in particular to a material lifting transportation overload protection early warning system. Comprising a data acquisition module which is used for monitoring the load condition of transportation equipment in real time and comprises a weight acquisition device, a current sensor, an acceleration sensor, a vibration sensor and a displacement sensor; the control module is connected with the data acquisition module, and is used for secondarily judging whether the equipment has the overload condition or not according to the offset of the material reaching the preset point position when the equipment has the overload condition according to the dynamic load characteristic value, or reducing the acceleration of starting the equipment, and reducing the acceleration of starting the equipment when the secondary judgment equipment has the overload condition. Determining an overload reason according to the current fluctuation value of the motor; and the early warning module is connected with the control module and is used for sending out an early warning signal according to a judgment result of the control module. According to the invention, the sensitivity of the overload protection early warning system is improved.

    本发明涉及过载预警技术领域,尤其涉及一种物料提升运输过载保护预警系统。包括:数据采集模块,其用于实时监测运输设备的负载情况,包括重量采集装置、电流传感器、加速度传感器、振动传感器和位移传感器;控制模块,其与所述数据采集模块相连,用以根据动态负载特征值判定设备存在过载状况时,根据物料到达预设点位的偏移量二次判定设备是否存在过载状况,或,降低设备启动的加速度,以及在二次判定设备存在过载状况时,根据电机的电流波动值确定过载原因;预警模块,其与所述控制模块相连,用于根据所述控制模块的判定结果发出预警信号。本发明提高了过载保护预警系统的灵敏度。
