Abstract

PURPOSE:To make it easy to control a power supply in each system by connecting the 1st and 2nd power supply control devices and plural power supply devices to be controlled to the 1st and 2nd power supply connection interfaces and mutually supervising both the power supply control devices through the interfaces. CONSTITUTION:The 1st and 2nd power supply control devices 1, 2, instruct the ON/OFF of the power supply devices 3 (3-3-3-n) to be controlled through the 1st and 2nd power supply connection interfaces 11, 12 respectively. The interfaces 11, 12 make both the control devices 1, 2 supervise each other so that instruction to turn on/off the power supply devices 3 to be controlled is not simultaneously executed by the 1st and 2nd control devices 1, 2. Consequently, transmitting circuits in the respective control devices 1, 2 are controlled so as not to be simultaneously driven and data are received by the 1st and 2nd receiving circuits included in each power supply device 3 to be controlled from the power supply control device of which transmission line is not fixed on a logical zero level.
