Abstract: The present invention discloses an identification number numbering method and a multipoint communication system. The identification number numbering method includes the following steps: sending an identification number packet to a multipoint communication bus by a master device; receiving the identification number packet via the multipoint communication bus, and temporarily storing an identification number according to the identification number packet by a first slave device; changing a voltage level of a master device control output pin of the master device; and when the first slave device determines that a voltage level of a first control input pin coupled to the master device control output pin is correspondingly changed, updating a first slave device identification number of the first slave device according to the identification number.

Abstract: A wireless power supply apparatus including a signal transmitting terminal and a signal receiving terminal is provided. The signal transmitting terminal encodes a digital data into a control signal and transmits a power supply signal in a manner of wireless communication according to the control signal. The signal receiving terminal receives the power supply signal from the signal transmitting terminal in the manner of wireless communication. The signal receiving terminal converts the power supply signal into a power source signal and a data signal and decodes the data signal into the digital data.
