Problems solved by technology

At this time, when sending bit 1 or bit 0, there must be a bit represented by a low level. Generally, a low level is a voltage value with a level of 0 or a small value, and generally cannot achieve the purpose of charging.
It can be seen that there is a problem of low charging efficiency in the encoding method of the prior art
[0003] In addition, in some existing signal transmission technologies, although high level and low level are not used to represent bit 1 or bit 0 encoding, but instead use different time intervals to distinguish different bit values, for example, bit 00 is represented by T+t1, bit 01 is represented by T+t2, bit 10 is represented by T+t3, and bit 11 is represented by T+t4. Using this existing signal transmission technology, the time required to transmit different bit values ​​is longer Long, the encoding efficiency of data bits is low, which increases the burden and cost of the sender and receiver

Embodiment 1

[0052] This embodiment provides a data sending method, such as figure 1 Shown, including:

[0053] Step S101: Obtain a bit sequence of data to be sent.

[0054] Specifically, when the data sender needs to transmit data, it generates or receives data to be sent from an external device, converts the data to be sent into a bit sequence corresponding to the data to be sent, or directly receives the data sent by the external device The bit sequence of the incoming data to be sent. The data to be sent may be a data frame to be sent by the data sender, and the bit sequence of the data to be sent may include information such as a data frame header, transmission data, and data frame end. Such as figure 2 Shown is an example of a data bit sequence to be sent (ie, a data frame), which includes a data frame header SOF, n bytes of transmission data, and a data frame end EOF. The data frame header SOF and data frame end EOF can be Each communication has a fixed bit string with a fixed number ...

Abstract

The invention provides a data transmitting method and device. The method includes: obtaining a bit sequence of data to be transmitted; and continuously transmitting a waveform sequence corresponding to bits in the bit sequence according to the bit sequence of the data to be transmitted, wherein a first waveform sequence represents a first data bit, a second waveform sequence and a third waveform sequence represents a second data bit separately, the first data bit is either 1 or 0, the second data bit is the other one of 1 and 0, and when at least two continuously transmitted bits are the second data bits, the waveform sequence corresponding to the first bit in the at least two consecutively transmitted bits is the second waveform sequence, and the waveform sequences corresponding to the second bit and the subsequent bits are the third waveform sequences. By using the data transmitting method, an apparatus can acquire as much electric energy as possible and improve power supply efficiency without affecting data transmission efficiency.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to a data transmission method and device. Background technique [0002] In the case of a wired electrical connection between the two communication parties, the sender and the receiver can transmit data through changes in level, that is, the sender can control the level between the two to control signal transmission. At this time, since a high level is inevitably maintained between the two, one party can use the high level to charge itself at this time, so as to achieve the purpose of charging while communicating. However, in the prior art, a high level and a low level are usually used directly to represent the coding mode of bit 1 or bit 0, that is, when the sender wants to send bit 1, the level on the line is maintained at a high level; When the sender wants to send bit 0, the level on the line remains low. At this time, when sending bit 1 or bit 0, there must be a bit rep...
