摘要
介绍了一种交流调压调速电梯的双微机控制系统。主微机实现电梯集选控制功能和控制电梯电力拖动运行状态。副微机完成电力拖动理想速度曲线的给定和停层时的位置控制。微机之间的信息交换保证系统可靠性的提高。系统具有良好的技术性能和经济效益。已在生产中得到推广应用。
A double microcomputer-based variable voltage-regulated speed control system for A. C. motor drived elevators is introduced in this paper. The main microcomputer functions as the elevator collective selective control and status control of power drive system. Another microcomputer works for the generation of set-speed signal and the position control when an elevator landing. The rapid data exchange between the two microcomputers greatly improves the system reliability. This motor control system possesses a high technological quality and wide economic benefits, thus getting a wide application in practical situations.
