Abstract

The utility model relates to a full selective elevator control system, in particular to an elevator control system adaptable to short storey distances and remotely driving a traction machine, which comprises a controller, an AC-DC-AC frequency converter and an output contactor. The controller outputs driving signals to the output contactor which feeds back contactor status signals to the controller, and the controller also outputs operating instruction, direction instruction and speed instruction to the AC-DC-AC frequency converter which sends status feedback signals to the controller. Besides, the AC-DC-AC frequency converter outputs control signals to the output contactor, and the controller acquires information about positions of an elevator cabin by collecting the signals of an upper sensor, a lower sensor and a level sensor which are arranged at the top portion of the elevator cabin. The elevator control system has the advantages of being capable of realizing full selective control of an elevator in hoist ways with short storey distances and multivariate storey distances, enabling elevator control devices to remotely drive a traction machine so as to drive the elevator cabin to move, saving long-distance encoder pulse transmission wires and lowering costs.
