Title:
DIRECT-CURRENT POWER LINE CARRIER TYPE COMMUNICATION CIRCUIT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/007646
Kind Code:
A1
Abstract:
The present application relates to the technical field of direct-current power line carriers, in particular to a direct-current power line carrier type communication circuit and method. The direct-current power line carrier type communication circuit comprises: a master unit, and at least one slave unit, the slave unit being connected to the master unit by means of a direct-current carrier power line, the master unit supplying power to the slave unit by means of the direct-current carrier power line, and interaction information between the master unit and the slave unit being transmitted by means of the direct-current carrier power line. A communication-related circuit in the master unit comprises a master control power supply, a master controller and a master switching circuit; a communication-related circuit in the slave unit comprises a slave control power supply, a slave controller, a slave sensing circuit, a non-return device, a power storage circuit, a slave switching circuit A and a load. Without providing a special communication port, the direct-current power line carrier type communication circuit and method of the present application can realize interactive cooperation amongst multiple direct-current electric appliances by means of direct-current power lines, thus achieving simple structure and low hardware cost, and having higher practical value.
