Claim Text:
1. A signal line power receiving circuit, comprising: a signal processing unit; a power unit; a signal interface, which transmits and receives data signals and receives power signals via a first signal line and a second signal line; a first isolation unit, connected between the signal processing unit and the signal interface, the first isolation unit isolating the power signals in the first signal line from the signal processing unit so that the signal processing unit transmits and receives the data signals via the first signal line; a first filter unit, connected between the power unit and the signal interface, the first filter unit filtering the data signals in the first signal line and supplying the power signals to the power unit; a second isolation unit, connected between the signal processing unit and the signal interface, wherein the second isolation unit isolates the power signals in the second signal line from the signal processing unit so that the signal processing unit transmits and receives the data signals via the second signal line; and a second filter unit, connected between the power unit and the signal interface, wherein the second filter unit filters the data signals in the second signal line and supplies the power signals to the power unit.
