<p>PURPOSE:To prevent an entire system-down by deciding the priority of control operation in advance based on each power consumption of plural electric devices so as to control the plural electric devices. CONSTITUTION:An in-rash current and a normal current of electric devices 31,32-3n which are energized are detected and the data is stored in a RAM 14 together with an address. When all the data is stored in the RAM 14, a priority decision section 2 decides the priority operating the electric devices 31,32-3n in the larger inrash current order. An arithmetic control section 12 receiving a control signal obtains the sum of the usual current by reading the data of an electric device in the ON state among the electric devices 31,32-3n from the RAM 14 and calculates a current margin from the total sum. Then the plural electric devices 31 (or 32-3n) being controlled systems of the control signal are controlled in the ON state sequentially based on the priority.</p> |
