SAFETY ELEVATOR
收藏资源简介:
A safety elevator including: a position detection sensor (4) which outputs an output pattern having a plurality of outputs in accordance with the position of an elevator car (100) moving up/down; a position database (23) which stores a specific output pattern corresponding to each specific position in an up/down direction; a car position data portion (22) which stores the output pattern whenever the output pattern of the position detection sensor (4) changes; and a transition database (24) which stores the specific output pattern expected in accordance with the specific position as predicted transition data; wherein when the output pattern does not coincide with any one of the predicted transition data at the time of arrival of the elevator car (100) at the specific position, it is determined as a failure.
一种安全电梯,包括:位置检测传感器(position detection sensor,4),其根据沿上下方向移动的电梯轿厢(elevator car,100)的位置,输出包含多路输出的输出模式;位置数据库(position database,23),其存储与升降方向上各特定位置对应的特定输出模式;轿厢位置数据模块(car position data portion,22),其在位置检测传感器(4)的输出模式发生变化时存储该输出模式;过渡数据库(transition database,24),其存储依据特定位置得到的预期特定输出模式,作为预测过渡数据;其中,当电梯轿厢(100)抵达特定位置时,若该输出模式与任一预测过渡数据均不匹配,则判定为故障。
