摘要
针对计算机控制电梯干扰大、可靠性要求高的特点,提出电梯设计中必需的五种接口设计原理并分析其优缺点,把接口挂接到“二极锁存总线”以提高抗干扰性设计。
Since the environment of elevator has great noises and electrical interference,reliability is the main concern for a cornputer controled elevator design.This paper presents fivetypes of necressary interfacing designs and their strong and weak points,and a new concept of sec-ondary latched bus for these interface。The system performance has proved to be good.
