Abstract

Abstract An apparatus for controlling an elevator comprising control data setting means for setting control data indicative of an environment where the elevator is installed and for generating a control signal representative thereof; cage position detecting means for detecting position of a cage of the elevator to generate a cage position signal representative thereof; cage position converter means connected to receive the control signal and the cage position signal for performing a predetermined logical operation to generate a converted cage position signal corresponding to the environment; position indicator data setting means for setting a position indicator data representing the position of the cage in response to the converted cage position signal generated by the cage position converter means; and position indicator signal producing means for producing a position indicator signal on the basis of the converted cage position signal and the position indicator data. The cage position converter element performs a predetermined logical operation in accordance with the position indicator data and the cage position signal indicative of a floor level of zero detected by the cage position detecting element.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 143 words
An apparatus for controlling an elevator comprising: control data setting means for setting control data indicative of an environment where the elevator is installed and for generating a control signal representative thereof; cage position detecting means for detecting position of a cage of the elevator to generate a cage position signal representative thereof; cage position converter means connected to receive said control signal and said cage position signal for performing a predetermined logical operation to generate a converted cage position signal corresponding to said environment; position indicator data setting means for setting a position indicator data representing the position of the cage in response to the converted cage position signal generated by said cage position converter means; and position indicator signal producing means for producing a position indicator signal on the basis of said converted cage position signal and said position indicator data.
Claim 2
Independent Claim 143 words
An apparatus for controlling an elevator comprising: control data setting means for setting control data indicative of an environment where the elevator is installed and for generating a control signal representative thereof; cage position detecting means for detecting position of a cage of the elevator to generate a cage position signal representative thereof; cage position converter means connected to receive said control signal and said cage position signal for performing a predetermined logical operation to generate a converted cage position signal corresponding to said environment; position indicator data setting means for setting a position indicator data representing the position of the cage in response to the converted cage position signal generated by said cage position converter means; and position indicator signal producing means for producing a position indicator signal on the basis of said converted cage position signal and said position indicator data.
Claim 3
Dependent Claim 51 words
An apparatus for controlling an elevator according to claim 1 wherein said cage position converter means performs a logical operation given by FS+α-β where FS denotes the cage position signal position detecting means, and α and β denote control data indicative of the environment set by said control data setting means.
Claim 4
Dependent Claim 36 words
An apparatus for controlling an elevator according to claim 2 wherein said cage position detecting means detects a lowest position of the cage and generates a cage position signal indicative of a floor level of zero.
Claim 5
Dependent Claim 35 words
An apparatus for controlling an elevator according to claim 3 wherein said control data setting means sets the control data α based upon the position indicator data set by said position indicator data setting means.
Claim 6
Dependent Claim 31 words
An apparatus for controlling an elevator according to claim 4 wherein said control data setting means set the control data based upon the cage position signal indicative of the floor zero.
Claim 7
Dependent Claim 27 words
An apparatus for controlling an elevator according to claim 1 further including a position indicator connected to receive said position indicator signal for displaying corresponding cage position.
Claim 8
Dependent Claim 18 words
An apparatus for controlling an elevator according to claim 6 wherein said position indicator is a seven-segment indicator.
Claim 9
Dependent Claim 18 words
An apparatus for controlling an elevator according to claim 6 wherein said position indicator is an eight-segment indicator.
Claim 10
Dependent Claim 18 words
An apparatus for controlling an elevator according to claim 6 wherein said position indicator is a sixteen-segment indicator.
