Title:
ELEVATOR CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP3038126
Kind Code:
B2
Abstract:
PURPOSE: To block invaders entering warning blocks through an elevator by controlling the operation controls such as lift, stop, skip, and others of an elevator by one main controller together with the organization of guard such as start and termination of guard of each block.
CONSTITUTION: When a local controller 5 is brought under the alert start condition by a guard mode setting device 500 after local controllers 3 and 4 on the second floor are brought under warning start condition by guard mode setting devices 300 and 400, signals are transmitted from a local bus 1/F of the local controller to a main controller 1 through a local bus 17. By this, in the main controller 1, all guard blocks on the second floor are brought under the alert start condition. Therefore the main controller 1 transmits second floor skip signals to the local controller 12 located in a machine room through the local bus 17. Thus invaders can be blocked without stopping a car at the second floor.
