Abstract

Disclosed are an elevator using variable communication protocol and its control method which makes it possible to operate elevators which uses different communication protocols between an operation control part controlling an operation of an elevator and an elevator hall and between an operation control part and an up and down passage operation part. The elevator using a variable communication protocol comprises an up and down passage operation part which detects and outputs an elevator call and a floor selection signal from a passenger of an elevator and displays an operation state of the elevator based on the call and the floor selection; an elevator operation control part which outputs an operation control signal allowing the elevator to work in accordance with a call and floor selection signal of the elevator from the up and down passage operation part and an operation display signal for a display of the operation state and the arrival state of the elevator; and a protocol conversion part which converts a communication protocol of the up and down passage operation part or the elevator operation control part for a data communication between the up and down passage operation part and the elevator operation control part hen different communication protocols are used in terms of the signals between the up and down passage operation part and the elevator operation control part.
