PROBLEM TO BE SOLVED: To provide the centralized management system of a power supply control device for preventing a deterioration in security against an attack from the outside.SOLUTION: Terminal equipment 60 transmits monitor condition data 70b to 73b indicating the individual monitor conditions of power supply control devices 10 to 13 via a network 40 to a management server 50, and the management server 50 stores the monitor condition data 70b to 73b received from the terminal equipment 60 in a storage part 70. The power supply control devices 10 to 13 include a monitor condition change part for periodically performing access via a router 30 and the network 40 to the management server 50 at different timing, and for determining whether or not the monitor condition data for itself have been changed, and for, when the monitor condition data for itself are changed, changing its own monitor condition on the basis of the changed monitor condition data.SELECTED DRAWING: Figure 1 |
