Single-wire transmission interface and single-wire transmission method and power supply system adopting single-wire transmission method

摘要

The present invention discloses a single-wire transmission method, which includes: providing a transmission signal including alternating high and low levels through a single-wire, wherein a period of one of the high and low levels defining a reference time and a period of the other of the high and low levels defining a content time; determining a relative relationship between the reference time and the content time; when the content time is smaller than a proportion of the reference time, defining the content time to express a first meaning; and when the content time is larger than the proportion of the reference time, defining the content time to express a second meaning.

1. A single-wire transmission method, comprising:
providing a transmission signal including alternating high and low levels through a single-wire, wherein: (1) a time period of the high level defines a reference time and a time period of the low level defines a content time; or (2) a time period of the low level defines a reference time and a time period of the high level defines a content time; and determining a relative relationship between the reference time and the content time which immediately follows the reference time by comparing the reference time and content time; when the determined relative relationship determines the content time is shorter than a first proportion of the reference time, defining the content time to express a first meaning; and when the determined relative relationship determines the content time is longer than the first proportion of the reference time, defining the content time to express a second meaning.
