PROBLEM TO BE SOLVED: To provide an elevator control device that enables updating of a control program through remote control without interrupting an operation service of an elevator.SOLUTION: An elevator control device 20 in one embodiment includes a remote monitoring device 30, a program storage memory 22, two program execution memories 23, 24 and a control section 21. The remote monitoring device 30 receives a control program for updating from a monitoring center 60. The program storage memory 22 stores the control program for updating. The program execution memories 23, 24 are selectively used for an operation control of an elevator. The control section 21 uses one memory of the program execution memories 23, 24 that is not used for the operation control of the elevator as an updating target, transfers the control program for updating to the updating target memory to update the program and then, switches to the updating target memory at predetermined timing to perform the operation control of the elevator.SELECTED DRAWING: Figure 1 |
