Intelligent scaffold anti-falling electric wave interference preventing method
The invention discloses an intelligent scaffold anti-falling electric wave interference preventing method. An intelligent scaffold control system is used for controlling ascending and descending of a scaffold. Gear mechanisms are driven to rotate through lifting motors, rotating speed sensors send out rotating speed pulses, collecting counters collect pulse signals, count the pulse signals and send the pulse signals to a PLC, the PLC converts the pulse number into ascending and descending heights according to set coefficients after receiving the pulse number, compares the ascending and descending heights with the set heights, and automatically controls the lifting motors at corresponding positions to stop after the set heights are reached. In the ascending and descending process, the PLC compares the heights of all positions, calculates the ascending and descending height differences among the positions and controls the operation state of the lifting motor at the position with the largest difference when the maximum difference exceeds the allowable value to achieve the synchronous ascending and descending at all the positions. The PLC controls an anti-falling device to act. According to the intelligent scaffold anti-falling electric wave interference preventing method, operation is convenient, work is safe, and controllability is good.
