Patent attributes
An elevator control device which realizes, in a multi-car system, operation control superior in transportation efficiency. A first shunting device outputs a first shunting command for moving a car which has responded to a call request to a shunting floor. A blocked state detection device detects a blocked state in which a succeeding car cannot run due to a preceding car being in a standby state at a shunting floor, and outputs blocked-state-generation information. A second shunting device outputs a second shunting command for moving the preceding car in the standby state to a new shunting floor based on the blocked-state-generation information. Further a collective operation control device collectively controls the operation of each car based on information for each car, the first shunting command from the first shunting device, and the second shunting command from the second shunting device.
