Abstract
A transmission cable includes a cable body, a return control circuit, and a determining circuit. The cable body has a first end and a second end, and the cable body includes a first wire and a second wire. The return control circuit is located at the second end and configured to selectively electrically connect the first wire to the second wire. The determining circuit is located at the first end, and configured to determine an electrical property of the second wire and output a first signal when the foregoing electrical property is less than a threshold.
Claims20
A transmission cable, comprising:
- a cable body, having a first end and a second end, the cable body comprising a power supply wire and a signal wire;
- a return control circuit, located at the second end, and configured to selectively electrically connect the power supply wire to the signal wire;
- and
- a determining circuit, located at the first end, and configured to determine a return voltage of the signal wire and output a first signal when the return voltage is less than a threshold.
A power supply device, comprising:
- a power supply circuit, configured to provide a power supply and comprising a determining circuit;
- a cable body, having a first end and a second end, the cable body comprising a power supply wire, a signal wire, and a ground wire, and the power supply circuit providing the power supply to the first end corresponding to the power supply wire and the ground wire;
- and
- a return control circuit, located at the second end, and configured to selectively electrically connect the power supply wire to the signal wire, wherein
- the determining circuit is configured to determine a return voltage of the signal wire and output a first signal when the return voltage is less than a threshold.
