For mature control technology, make the various performance of the elevator also obtained fast development, its movement technology also has already progressed to a variety of leveling regulating speed control technology. The original relay control was replaced by PLC instead. So this article is primarily concerned with and use PLC to control the elevator through a variety of plan and design, let us can more convenient control, elevator in the elevator at the same time told us also bring physical and mental pleasure, more comfortable, not so boring like before.
