Embodiment 1

[0027] see figure 1 , an embodiment of the present invention provides a method for processing infrared data, including:

[0028] 101. Receive the infrared signal sent by the infrared sending setting, and acquire the pulse width value of the first data waveform in the data waveform of the infrared signal. The data waveform includes a high-level pulse and a low-level pulse.

[0029] It should be noted that the infrared signal may be sent by the main remote controller or an infrared signal transmitter connected to a computer or a single-chip microcomputer board, which will not be repeated here. According to the idea of ​​the present invention, a learning type slave remote controller corresponding to the infrared emitting device can be provided to receive the infrared signal sent by the infrared emitting device.

[0030] For example, in the prior art, the infrared signal is encoded with Microsoft longtime encoding, and the following infrared encoded data is obtained:

[0031] 36...

Embodiment 3

[0086] see image 3 , an embodiment of the present invention provides an infrared data processing device, including:

[0087] The receiving unit 301 is used to receive the infrared signal sent by the infrared sending setting, and obtain the pulse width value of the first data waveform in the data waveform of the infrared signal, and the data waveform includes a high-level pulse and a low-level pulse; Obtain the pulse width value of the data waveform after the first data waveform in the infrared signal in sequence;

Abstract

The invention provides an infrared data processing method, a processing device and a decoding method to solve the problems that in the prior art, the data quantity of infrared data coded with pulse is large, and large storage space needs to be occupied. The processing method includes the steps that infrared signals are received, the pulse width value of a first data waveform in data waveforms of the infrared signals is obtained and serves as a first classification data value and is assigned to a first coded character, and the first coded character is stored in character coded data; pulse width values of other data waveforms in the infrared signals are sequentially obtained, whether the absolute value of the difference between the current pulse width value and the (p-1)th classification data value and the absolute values of the differences between the current pulse width value and previous classification data values are within a preset threshold range or not is judged, if yes, the coded character assigned by the corresponding classification data value replaces the current pulse width value and is stored, and if not, it is determined that the current pulse width value is the pth classification data value, and the pth coded character replaces the current pulse width value and is stored in the character coded data.

Description

technical field [0001] The invention relates to the technical field of infrared data encoding and decoding, in particular to an infrared data processing method, processing device and decoding method. Background technique [0002] Existing infrared remote control signals all adopt some kind of signal encoding method, the difference is only the length of the signal time and the number of digits. Commonly used signal coding methods are: pulse coding, that is, different coding methods according to the pulse width, which is adopted by Sony (CSONY) company. Interval coding, that is, a method of coding according to the length of the pulse interval, is also often called the REC-80 method. Conversion coding, that is, the method of coding according to the change of pulse and interval time sequence, is also called RC-5 method. [0003] In the way of encoding infrared data in the above-mentioned manner, it is necessary to record the pulse width value of each high-level pulse and low-l...
