Abstract

A control device has a monitoring section that monitors an amount of electric energy of a first machine, and a power supply controller that controls power supply of a second machine in accordance with an amount of electric energy of the first machine and schedule information indicative of an operation schedule of each of the first machine and the second machine.

Claims

1. A control device comprising:

a monitoring section that monitors an amount of electric energy of a first machine; and

a power supply controller that controls power supply of a second machine in accordance with an amount of electric energy of the first machine and schedule information indicative of an operation schedule of each of the first machine and the second machine,

wherein, in a case where the amount of electric energy of the first machine is less than a first threshold and the schedule information indicates that a current point in time is included in a scheduled stop time period, the power supply controller carries out a first stopping process in which the power supply controller controls the power supply of the second machine to be turned off or controls the second machine to be in an electric power saving mode,

wherein, after carrying out the first stopping process, the power supply controller carries out a first start-up process in which the power supply controller controls, in accordance with the schedule information, the first machine and the second machine to be started up by next scheduled operation time period at the latest, and

wherein the power supply controller sets a start-up starting time in accordance with a difference between a start time of the scheduled stop time period indicated by the schedule information and a point in time at which the first stopping process is carried out, and carries out the first start-up process in a case where time, elapsed from the point in time at which the first stopping process is carried out, reaches the start-up starting time.
