Abstract
The utility model relates to an intelligent control system for an attached-type lifting scaffold. The intelligent control system for the attached-type lifting scaffold includes at least two satellite boxes installed on station points of the body of the scaffold. Input terminals of the satellite boxes are connected with a gravity sensor and a displacement sensor respectively. Output terminals of the satellite boxes are connected with a contactor of a low-speed electronic loop chain lifting machine through a control circuit. Input/output terminals of the satellite boxes are in communication with an upper computer through a communication circuit. The intelligent control system for the attached-type lifting scaffold provided by the utility model is simple in structure and convenient to install. Since the upper computer is composed of a portable PC, an RS485 communication circuit and an STC-28 single-chip microprocessor, the communication range between the upper computer and the satellite boxes can be comparatively long and the communication stability and reliability can be guaranteed. When overload occurs in a station, the intelligent control system for the attached-type lifting scaffold does not run even when an operate gives out a lifting or descending instruction and a prompt can be given out. The operation of lifting or descending can be realized only after load of all stations are in a normal range, so that potential safety hazards caused by error operation of the operator are avoided.
