The invention discloses a safety detection control method for an intelligent construction hoist, which comprises the following steps: a controller calculates real-time power P, and calculates torque change values delta T of a current scanning period and a previous scanning period in real time; the maximum torque change value of the deceleration interval is delta Ta, the maximum torque change value of the non-deceleration interval is delta Tb, and the display sets an early warning threshold coefficient X (Xgt; = 1), an alarm early warning threshold coefficient Y (Ygt; x); when the elevator is used in the deceleration interval, if delta Tgt; if X * delta Ta is equal to X * delta Ta, the controller sends an early warning signal to the display screen, and the display screen displays a maintenance prompt; if delta Tgt; if Y * delta Ta is equal to Y * delta Ta, the controller sends an alarm signal to the display screen and stops running immediately; when the elevator is used in a non-deceleration interval, if delta Tgt; if X * delta Tb is equal to X * delta Tb, the controller sends an early warning signal to the display screen, and the display screen displays a maintenance prompt; if delta Tgt; if the delta Tb is equal to Y * delta Tb, the controller sends an alarm signal to the display screen, and the operation is stopped immediately.

    本发明公开一种智能施工升降机的安全检测控制方法,包括以下步骤:控制器计算出时时功率P,并实时计算当前扫描周期现与上一扫描周期上的转矩变化值|ΔT|;减速区间的最大转矩变化值为|ΔTa|,非减速区间的最大转矩变化值为|ΔTb|,显示器设定预警阀值系数X(X>=1)、报警预警阀值系数Y(Y>X);当升降机于减速区间使用过程中,若|ΔT|>=X*|ΔTa|,则控制器发送预警信号给显示屏,显示屏显示检修提示;若|ΔT|>=Y*|ΔTa|,则控制器发送报警信号给显示屏,并立即停止运行;当升降机于非减速区间使用过程中,若|ΔT|>=X*|ΔTb|,则控制器发送预警信号给显示屏,显示屏显示检修提示;若|ΔT|>=Y*|ΔTb|,则控制器发送报警信号给显示屏,并立即停止运行。
