PURPOSE:To provide a control unit of a group control elevator that is able to uniformize the operating frequency of each elevator car. CONSTITUTION:This control unit is provided with three frequency measuring means 5a to 5c measuring each operating frequency of elevator cars 1 to 3 being on standby at the reference floor, a selecting means 6 selecting the elevator car less in the operating frequency on the basis of operating frequency data to be outputted from these frequency measuring means 5a to 5c, and three signal outputting means 7a to 7c outputting a preceding command signal of the elevator car selected by this selecting means 6, respectively, through which the selected car is made so as to be preferentially driven. With this constitution, operation efficiency for maintenance is well improvable. |
