Embodiment 1

[0084] figure 2 A schematic flowchart of a decoding method according to an embodiment of the present invention is shown.

[0085] Such as figure 2 As shown, the decoding method according to an embodiment of the present invention includes: Step 202, in the process of receiving the data frame generated by the encoding method described in any of the above technical solutions, determine the data frame according to the transmission frequency band and transmission time The data header; step 204, after determining the data header, detect the acquisition time of the byte header of the data frame, and record the time slice of any one data bit of the data frame; step 206, judge whether the preset time slice and the time slice Match; step 208, judge any bit of data according to the matching result to be binary data 0 or binary data 1, to complete the frame-by-frame decoding of the data frame, wherein the preset time slice includes the preset first corresponding to binary data 0 time ...

Embodiment 2

[0091] image 3 A schematic flowchart of a decoding method according to another embodiment of the present invention is shown.

[0092] Such as image 3 As shown, the decoding method according to another embodiment of the present invention includes: step 302, first initialize the single-chip microcomputer, enter the while loop, and start to interrupt and record the current pulse width frequency; step 304, judge whether to perform data processing according to the frequency of the data frame Transmission, if yes, skip the judgment data header inspection, if not, then judge whether the data header is established, where the transmission frequency band of the byte header and the data header are the same, judge by the transmission time of the two, M represents the length of the byte header , N is the length of the data header, both M and N are positive integers, and N≥3×M; step 306, if it is determined that the data header is established, then initialize all array registers, and sta...

Embodiment approach

[0117] (1) Large time slice of the data header: record how many frequencies have been recorded from the first correct data header frequency to the N-length correct data header frequency, including correct and wrong frequencies.

[0118] (2) The small time slice of the data header: the correct frequency number of the data header, the small time slice of the data header > the large time slice of the data header / 2.

[0119] (3) Byte large time slice: record how many frequencies have been recorded from the first correct byte frequency to the frequency of the M length correct byte, including correct and wrong frequencies.

[0120] (4) Small time slice of byte header: the correct frequency number of byte header, small time slice of byte header > large time slice of byte / 2.

[0121] (5) Small time slice of 0-byte header: the correct number of 0-byte frequency, small time slice of 0-byte header > big time slice of byte / 2.

[0122] (6) 1-byte header small time slice: the correct numbe...

Abstract

The invention provides an encoding method, a decoding method, an encoding device, a decoding device and a household appliance. The encoding method comprises the following steps: performing data encoding by using a first frequency band, a second frequency band and a third frequency band in ultrasonic frequency bands, wherein the first frequency band is used for transmitting data headers or byte heads, the second frequency band is used for transmitting binary data 1 of byte bits, and the third frequency band is used for transmitting the binary data 0 of the byte bits; obtaining the binary data of to-be-transmitted specified bits, wherein any bit of data of the binary data is synthesized by the byte head and the corresponding byte bit; and synthesizing the data heads with the to-be-transmitted binary data to generate a data frame transmitted on the basis of the ultrasonic frequency bands by encoding, wherein the transmission time of the data heads is not equal to that of the byte heads. By adoption of the technical scheme, the communication cost is reduced, and the communication efficiency and accuracy are improved.

Description

technical field [0001] The present invention relates to the technical field of household appliances, and more specifically, to an encoding method, a decoding method, an encoding device, a decoding device and a household appliance. Background technique [0002] In related technologies, existing data communication schemes are usually based on the principle of electromagnetic radiation, such as RF communication, Wi-Fi communication, Bluetooth communication, and infrared communication, etc., all of which require corresponding communication modules to be installed at the sending end and receiving end to realize the communication function , which will undoubtedly increase the production cost of the product. [0003] In order to realize the data communication of the smart home itself, or the data communication between the smart home and terminal devices (such as mobile phones and servers, etc.), a low-cost and fast handshake communication method is needed. [0004] Therefore, how ...
