Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While the exemplary embodiments disclosed are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 is a flowchart of a method for learning codes of a remote control in embodiment 1 of the method of the present invention, and the method for learning codes of a remote control in embodiment 1 of the method of the present invention shown in fig. 1 includes:
Specifically, the keys of the universal remote controller are usually coded by infrared remote control, and the infrared remote control codes are usually combined by high level and low level, and different coding modes are represented by combining different levels with different durations. The period of one bit of the data code in the original information is generally within 0.1 ms to 10 ms. The duty ratio is defined as the ratio of the high level to the low level of 1 bit, and the duty ratio of 1 bit is usually 1:1.5-1:4, or 1.5:1-4: 1.
And step 20, calculating a time base according to the level duration.
Specifically, in the present embodiment, the processes of learning, storing, and retransmitting are performed after the original information is received, and only the duration of each level received is recorded regardless of the relationship between the durations of various levels in the original information and the combination thereof. Since there is a certain correlation between the level durations of each codeword in the original information regardless of the encoding method, in order to further improve the data storage capacity, the present embodiment calculates the reference time of the level durations in the original information, including calculating the minimum duration or the average duration, as the reference time, and compression-encodes the original information.
And step 30, coding the original information according to the time base to obtain the time base code of the key.
Specifically, the level duration in the original information is converted into a multiple of the time base, or a correlation coefficient between the level duration and the time base is calculated according to a preset correlation algorithm, or a variance between the level duration and the time base is calculated according to a preset probability statistical algorithm, and all the level duration in the original information is encoded according to a unified reference time base and one of a converted multiple value, a correlation coefficient and a variance value, so that the time base code with a high compression rate can be obtained.
In the method for learning codes of a remote controller provided by this embodiment, the minimum value of the duration of each level is determined by scanning the duration of the level in the original information of the key, and the minimum value is used as a time base, and then the time base codes of the key are obtained and stored by using the original information and the time base. The time base is used as the reference time length for coding the level duration, can be compatible with remote control coding formats of various types of electrical appliances on the basis of not considering the specific coding meaning and the interrelation of the level duration, and has the advantages of simple and easy processing mode and low implementation cost.
In one embodiment, after the step of storing said time-based encoding, said method further comprises: obtaining the sending information of the key according to the time base and the time base code; and transmitting the sending information.
Specifically, when the information of the key is required to be sent according to the stored time base code, the duration of each level of the actually transmitted information can be calculated only according to the stored time base code and the time base, and the information is transmitted.
According to the remote controller code learning method provided by the embodiment, the stored time base code and the time base are simply calculated, and then the sending information of the key for sending can be obtained, so that the universal remote controller using the method provided by the embodiment is simple and convenient to send and calculate, good in implementability and wide in application range.
Fig. 2 is a flowchart of packet decoding of a remote control coding learning method in embodiment 2 of the method of the present invention, and the remote control coding learning method in embodiment 2 of the method of the present invention shown in fig. 2 includes:
and step 21, acquiring the duration of the high level and/or the duration of the low level in the original information.
Specifically, the original information includes a high level and a low level, and the high level and the low level are used for expressing different code words in the original information according to different encoding modes, and duration of the code words is in a certain association relationship with each other, so that only the duration of the high level is obtained, or only the duration of the low level is obtained, or both the duration of the high level and the duration of the low level are obtained for subsequent time base calculation, and the setting is performed according to actual conditions.
And step 22, determining the duration smaller than a preset time base threshold value in the high level duration and/or the low level duration as the duration to be averaged.
Specifically, since in reality, to represent '1' and '0' of the data code in the original information, the time when the high level and the low level are received is significantly different, and is also the data '1', the time when the high level and the low level are received may be 0.7 to 1.3 times different. Therefore, it is necessary to calculate an accurate time base for subsequent learning coding by considering the difference of the duration time of each level in practice, and the preset time base threshold value can be adopted to adjust according to the requirement to calculate a more accurate time base.
It is assumed that the array recording the original remote control encoding time is capture, and each value in the capture array records the duration of the high level or the duration of the low level of each segment in microseconds. The time base calculation method comprises the following steps:
firstly, scanning all values of the capture array, finding out the value with the minimum value, and recording the value as minValue.
Scanning all values of the capture array, if the value of one value is less than 1.5 minValue, determining the value as the time length to be averaged, and recording the number n of the time length to be averaged.
Step 23, calculating the total duration of all the durations to be averaged, and calculating the number of the durations to be averaged; and calculating the time base according to the total duration and the number.
Specifically, all the durations to be averaged are accumulated to obtain a total duration sum, and then the time base is sum/n, that is, the obtained time base is the minimum value of the level duration calculated according to the actually received original information.
According to the remote controller code learning method provided by the embodiment, after the level duration time smaller than the preset time base threshold value is set as the time duration to be averaged according to the duration level in the received original information, the total time duration and the number of the time duration to be averaged are calculated, and the time base is obtained after averaging.
Fig. 3 is a schematic diagram of original information of a remote controller in embodiment 3 of the method of the present invention, and as shown in fig. 3, the original information is divided into a bootstrap code, a user code, and a data code, where the bootstrap code is a segment of high level and a segment of low level, and the bootstrap code is only the beginning of a valid key code. For the universal remote controller, the user code and the data code can be regarded as actual codes of the keys and can be unified into key data codes. The data code of each bit is also composed of a high level and a low level. In general, the pulse period of the pilot code is longer than the period of the data code. The period of the pilot code (time of high + low) is generally within 1 ms to 30 ms, and the period of one bit of the data code is generally within 0.1 ms to 10 ms. The time of the high level and the low level of a bit of the data code is a multiple of a time base, and usually the multiple does not exceed 4 times.
Fig. 4 is a flowchart of packet decoding of a remote control coding learning method in embodiment 3 of the method of the present invention, and the remote control coding learning method in embodiment 3 of the method of the present invention shown in fig. 4 includes:
Specifically, the same procedure as in example step 10 was repeated.
And step 20, calculating a time base according to the level duration.
Specifically, the same procedure as in step 20 of the example was carried out. When the original information includes the guide code and the data code, encoding is required to be performed based on different characteristics of the guide code and the data code, so as to improve the compression rate.
And step 31A, calculating the multiple of the level duration in the guiding information relative to the time base to obtain the guiding level multiple.
Specifically, since the durations of the high level and the low level of the pilot code are both long, the calculated values of the pilot high level multiple and the pilot low level multiple are also large.
And step 32A, carrying out binary coding on the guide level multiple to obtain a guide time base code of the guide information, wherein the code length of the guide time base code is a first code length.
Specifically, the first code length includes one byte (8 bits) to represent the pilot high level multiple and the pilot low level multiple, respectively, to sufficiently express the duration of the high level and the low level in the pilot code. The first bit length can be flexibly set according to the time base condition of the received original information.
And step 31B, calculating the multiple of the level duration in the data information relative to the time base to obtain the data level multiple.
Specifically, since the duration of both the high level and the low level in the data code is short, the calculated data high level multiple and data low level multiple are also small.
And step 32B, carrying out binary coding on the data level multiple to obtain a data time-base code of the data information, wherein the code length of the data time-base code is a second code length.
Specifically, the preset second code length includes two bits, such as 00 indicating that the multiple of the data high level or the multiple of the data low level is 1 time, 01 indicating that the multiple of the data high level or the multiple of the data low level is 2 times, 10 indicating that the multiple of the data high level or the multiple of the data low level is 3 times, and 11 indicating that the multiple of the data high level or the multiple of the data low level is 4 times. For the case of more than 4 times, the truncation is 4 times.
According to the level duration of the guide code and the data in the actually acquired original information, the length values of the first code length and the second code length can be flexibly obtained.
When the multiple of the data high level and the multiple of the data low level calculated according to the received original information are larger or smaller, the second bit length can be adjusted accordingly to better represent the multiple of the data high level and the multiple of the data low level, for example, with three bits, the multiple of the data high level or the multiple of the data low level can be represented as 8 times at most.
If the common C language is used for description, the data format of the code is as follows:
the method for learning codes of a remote controller provided by this embodiment encodes the pilot code and the data code respectively by presetting different bit lengths, and can perform adaptive time base coding according to different information codes in received original information, so that the obtained time base coding can more accurately express the original information.
