Abstract: An elevator renewal construction method includes a series of divided construction work steps, each being determined as such a unit that the elevator operation becomes normally possible after finishing of each of the divided construction work steps, wherein one of the series of the divided construction work steps comprises the steps of: replacing an old control panel of the existing elevator with a new control panel; connecting an old cable for an old car device, which has connected the old car device and the old control panel of the existing elevator to each other, to a communication conversion unit provided in the new control panel; and converting a new serial communication system to an old serial communication system by the new control panel via the communication conversion unit and the old cable to control the old car device through the old serial communication system.

Abstract: An elevator control device is configured to control a plurality of elevators disposed so as to provide an operation service to a plurality of floors. The elevator control device includes: a plurality of landing buttons, which are disposed at each of the floors, and to which an operating direction of the elevators is input; a car allocation unit configured to allocate one of the plurality of elevators to a landing call as a newly registered landing call each time the landing button is operated; and a drive control unit configured to provide the operation service of the allocated one of the plurality of elevators to the floor at which the landing call is generated.
