针对目前建筑物上安装的载物电梯的常规功能及老式控制系统中存在的问题,提出了以单片机控制板为核心的新型电梯控制系统的电路设计思路、工作原理及软件编程要点和软件框图. Aiming at the conventional functions of the load elevators installed in buildings and the problems existing in the old control systems, the circuit design ideas, working principles, software programming points and software block diagrams of the new elevator control system based on the SCM control board are proposed.
