Patent ID: 8918194

Claim:
A mounting-line power control device which controls power used by a mounting line group including a plurality of mounting lines each of which includes a component-mounted board production apparatus for producing a component-mounted board on which a component is mounted, said mounting-line power control device comprising: a target value obtaining unit configured to obtain, for each of the mounting lines, a target value for demand power which indicates power energy used in a first period; a priority obtaining unit configured to obtain a first priority level that is a priority level of each of the mounting lines for use of power; a target value changing unit configured to decrease the target value for the demand power used by a second mounting line in the first period when the demand power used by a first mounting line in the first period exceeds the target value for the first mounting line in the first period, the first mounting line being included in the mounting line group, and the second mounting line being included in the mounting line group and having the first priority level lower than the first priority level of the first mounting line; and a power usage changing unit configured to reduce power used in the first period by the component-mounted board production apparatus which is included in the second mounting line, such that the demand power used by the second mounting line in the first period does not exceed the decreased target value for the second mounting line in the first period.
