Zusammenfassung: | The utility model discloses a signal forwarding unit, equipment includes: including first singlechip, a coupling transformer, the 2nd coupling transformer, second single -chip microcomputer, first singlechip is connected respectively the terminal of a coupling transformer and no signal, a coupling transformer passes through the power line and connects the 2nd coupling transformer, the 2nd coupling transformer connects second single -chip microcomputer, second single -chip microcomputer connects the equipment that goes upward communication through communication device, first singlechip with second single -chip microcomputer's work bandwidth is the broadband communication bandwidth. The utility model discloses do not need to lay alone channel, reduce cost, first singlechip and second single -chip microcomputer's work bandwidth is the broadband communication bandwidth, and the broadband communication bandwidth is greater than the narrowband communication bandwidth far away, overcomes the low problem of narrowban |
