<p>PURPOSE:To control power supply to a terminal equipment economically by a center device by providing the terminal equipment with a power supply monitoring time and setting up the time by the center device to control current making of the power supply. CONSTITUTION:The terminal equipment is provided the power supply monitoring timer and the time setting is executed by the center device to control the current making of the power supply. For instance, a central processing unit (CPU)1 executes various kinds of operation and processing for the terminal equipment on the basis of a program stored in a memory 2 and controls the I/O operation between a timer 3 and a circuit control part 4. An internal power supply is supplied by a power supply device 5, the power supply is regulated so as to be turned on and off by a power supply control box 6 and a power supply line VB always supplying constant voltage is drawn from the power supply device 5 and connected to the power supply montoring timer 8 through a power supply converting circuit 7. If a message specifying the connection of the power supply is outputted from the center device, the information is set up and the power supply device 5 is automatically turned on through the power supply control box 6.</p> |
