Abstract
A shutdown device is disclosed. The shutdown device includes: at least one input port, configured to be coupled to a direct-current power supply; an output port, configured to be coupled to a power bus; at least one shutdown module, where one shutdown module corresponds to one input port, and includes at least one switching device, and the switching device controls an output power of the direct-current power supply; and a control module modulates a power control signal and a first communication signal to generate a first composite control signal, where the power control signal adjusts the output power of the direct-current power supply coupled to the input port; and the first composite control signal controls the switching device to work in a high-frequency switching state, to superimpose a current ripple signal comprising the first communication signal onto the power bus, thereby implementing data transmitting of the shutdown device.
