<p>PURPOSE:To avoid the application of a power supply owing to the wrong information and to control the state of a terminal equipment by an answer, by providing a circuit to which the power is supplied from a power supply that is free from the service interruption and a control circuit which holds the information supplied from an operator and gives an affirmative or negative answer. CONSTITUTION:When a receiving circuit 1 of a terminal equipment control circuit 8 of a power supply control system receives a power supply control command, a comparator 5 compares said command with the data proper to a terminal equipment held by a command holding circuit 4. If the coincidence is obtained from said comparison, the coincidence signal is sent to both an affirmative answer circuit 2 and a negative answer circuit 3. An operator secures the AND conditions between the make/break and permission/rejection of power supply by a command given from a controllable 1-bit memory circuit 6. Then a power supply device 7 is controlled by said AND conditions and at the same time this conditions are informed to a controller. Thus it is possible to secure the high reliability and high stability for the power supply control of a remote power supply control system.</p> |
