Abstract

PURPOSE: To be able to detect the status of troubles generated in a circuit system immediately by grasping it always bt means of polling from the center whether the power supply from the center has the legal voltage level in each part of the circuit system.
CONSTITUTION: Polling is always applied from center 1 to many terminal devices 7 trogether with TV signals and outputted inquiries and instructions are sent to the terminal devices as data signals. Each terminal device 7 with individual address code corresponds to the polling from center 1 and sends the necessary data to center 1 as an up-data signal. Main line amplifier 3, branch amplifier 4, branch equipment 5 and extension amplifier 6 are connected between center 1 and terminal devices 7 as the need arises and power is supplied from center 1 to these devices through main line 2 so as to operate the devices. Voltage supervisory equipment 8 equips the device, like terminal device 7, required for transmission/reception of up- and down- data. The center totalizes the up-data to analyize them and detects whether power source is legal or not at each position of the circuit system.
