Based on the hardware structure, the embodiment of the infrared remote control decoding processing method is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a decoding processing method for infrared remote control according to a first embodiment of the present invention.
In a first embodiment, the decoding processing method of the infrared remote control includes the following steps:
step S10, reading the current value of the register corresponding to the infrared remote control;
step S20, obtaining the system time difference between the system clock corresponding to the current reading operation and the system clock corresponding to the last reading operation;
step S30, according to the current value and the system time difference, identifying whether coding error occurs; if yes, go to step S40; if not, go to step S50;
step S40, performing coding error correction processing;
in step S50, encoding and decoding processing is performed.
At present, in the decoding application of infrared remote control, a processing mode of software query is a common means, and software actively reads a register all the time, and performs decoding processing after reading a numerical value. Read from the register lookup of the chip's remote control is a one-time duration of high and low, i.e., a one-cycle waveform. Most protocols in remote control coding generally represent a bit of 0 or 1 for one period, while some protocols (such as RCMM protocol) have four cases, such as 00, 01, 10 and 11 for one period.
Some platform infrared remote control (IR) registers, which are not cleared by reading once, remain there and cannot be cleared. In order to avoid the situation of repeated reading, in the current processing mode of software query, only the comparison between the value read this time and the value read last time is judged, whether the value read this time is the same as the value read last time is judged, if the same value is considered to be not updated, the different value is regarded as an effective value. This method is obviously flawed in that if it is true that there are two values that are the same, it is possible to discard the value once. Based on the problem, the invention provides an infrared remote control decoding processing method, which is suitable for the infrared remote control decoding processing device in the embodiment. In the embodiment, a processing method of software query and an algorithm management technology of time axis error correction are adopted, the condition of key value loss possibly occurring in software query is processed, the problem of probabilistic key value loss can be effectively solved, and the method is suitable for single-thread boot or single-chip microcomputer application.
Specifically, first, the current value of the register corresponding to the Infrared remote control (IR) is read. In the normal reading process, different values are processed first, and the same value is treated as not being updated. And when the read value changes, acquiring the system time difference between the system clock corresponding to the reading operation of the current read register and the system clock corresponding to the reading operation of the last read register.
Optionally, while executing the step S10, the following steps are also executed:
a, recording and storing a system clock corresponding to the current reading operation;
the step S20 includes:
step b, acquiring a stored system clock corresponding to the last reading operation;
and c, calculating the system time difference between the system clock corresponding to the current reading operation and the system clock corresponding to the last reading operation.
Optionally, while reading the value of the register each time, recording a system clock corresponding to the reading operation of reading the register, and saving the system clock. When the value of the register is read currently, the system clock corresponding to the reading operation of the current reading register is recorded, and the saved system clock corresponding to the reading operation of the last reading register is obtained. And subtracting the system clock corresponding to the reading operation of the current reading register from the system clock corresponding to the reading operation of the last reading register, and calculating the system time difference between the system clock corresponding to the current reading operation and the system clock corresponding to the last reading operation.
And then, comparing the current value with the system time difference according to the read current value and the system time difference between the system clock corresponding to the current read operation and the system clock corresponding to the last read operation, and identifying whether a coding error occurs, namely identifying whether a condition that key values are repeated and discarded occurs.
Optionally, the step S30 includes:
step d, comparing whether the difference between the current value and the system time difference exceeds a first preset range;
step e, if yes, identifying that coding errors occur;
and f, if not, identifying that no coding error occurs.
Normally, the system time difference of the system clock corresponding to two read operations is very close to the current value of the read register, and the error usually does not exceed half the minimum time period to the maximum. Based on this, in this embodiment, a first preset range for identifying whether the coding error occurs is preset, and optionally, the first preset range is a half time period of the register read operation. It will be appreciated that the first predetermined range may be set to other values.
And comparing the current value with the system time difference of the system clock corresponding to the current reading operation and the system clock corresponding to the last reading operation to obtain the difference between the current value and the system time difference, comparing the difference between the current value and the system time difference with a first preset range, and comparing whether the difference between the current value and the system time difference exceeds the first preset range. And if the difference between the current value and the system time difference exceeds a first preset range, identifying that coding errors occur and key value repetition occurs and discarding the key value. Otherwise, if the difference between the current value and the system time difference does not exceed the first preset range, the coding error is identified to not occur.
And when the coding error is not identified, carrying out coding and decoding processing according to normal operation. Otherwise, when the coding error is identified, the coding error correction is firstly carried out, the discarded key value is compensated, and then the coding decoding is carried out.
According to the scheme provided by the embodiment, the current value of the register corresponding to the infrared remote control is read, the system time difference between the system clock corresponding to the current reading operation and the system clock corresponding to the last reading operation is obtained, whether coding errors occur or not is identified according to the current value and the system time difference, if yes, coding error correction is firstly carried out, the discarded key values are compensated, and coding and decoding are carried out after completion, so that the decoding reliability of the infrared remote control is improved.
Further, a second embodiment of the infrared remote control decoding processing method according to the present invention is provided based on the first embodiment, and in this embodiment, as shown in fig. 3, before the step S20, the method further includes:
step S60, judging whether the read current value is valid; if yes, go to step S20; if not, go to step S70;
step S70, detecting whether the reading of the register is overtime; if yes, go to step S80; if not, returning to execute the step S10;
step S80, the operation ends.
In this embodiment, to avoid the invalid operation, after reading the current value of the register, it is determined whether the read current value of the register is valid. Typically, the time-coded value contains a start code and an end code, and optionally the validity of the current value is determined by identifying the start code and the end code.
As shown in fig. 4, only when the current value of the read register is valid, the current value of the register is saved, and the system time difference between the system clock corresponding to the current read operation and the system clock corresponding to the last read operation is obtained and saved, and then, whether a coding error occurs is identified according to the current value and the system time difference.
On the contrary, when the current value of the read register is invalid, whether the reading of the register is overtime is further detected. If the reading of the register is not timed out, the process returns to step S10 to read the current value of the register. If the register is read overtime, the operation is ended.
According to the scheme provided by the embodiment, after the current value of the register is read, whether the read current value is valid is judged, when the current value is valid, the current value of the register is stored, and the system time difference between the system clock corresponding to the current reading operation and the system clock corresponding to the last reading operation is acquired and stored, so that coding error recognition is performed, the accuracy of coding error recognition is improved, and the decoding reliability of infrared remote control is further improved.
Further, a third embodiment of the infrared remote control decoding processing method according to the present invention is proposed based on the first embodiment or the second embodiment, and in this embodiment, as shown in fig. 5, the step S40 includes:
step S41, supplementing a corresponding number of time code values based on the difference between the current value and the system time difference.
In this embodiment, when a code error is identified, a corresponding number of time code values are added according to a difference between a current value and a system time difference between a system clock corresponding to a current read operation and a system clock corresponding to a previous read operation, so as to implement code error correction processing.
Optionally, the step S41 includes:
step g, obtaining the difference between the current value and the system time difference;
step h, when the difference between the current value and the system time difference exceeds a time period, supplementing a time coding value, and returning to execute the step g until the difference between the current value and the system time difference does not exceed a time period;
step i, judging whether the difference between the current value and the system time difference exceeds a second preset range;
step j, when the difference between said current value and said system time difference is outside said second predetermined range, appending a time code value.
Based on the first embodiment, normally, the system clock difference of the system clock corresponding to two read operations is very close to the current value of the read register, and the error usually does not exceed half the minimum time period to the maximum. Therefore, in this embodiment, when a coding error is identified, as shown in fig. 6, according to the current value, the system time difference between the system clock corresponding to the current reading operation and the system clock corresponding to the last reading operation is subtracted from the current value to obtain the difference between the current value and the system time difference, and then it is determined whether the difference between the current value and the system time difference exceeds one time period of register reading. If the difference between the current value and the system time difference exceeds a time period read by the register, supplementing a self time coding value, and then continuing to perform the operation of subtracting the system time difference from the current value to obtain the difference between the current value and the system time difference until the difference between the current value and the system time difference does not exceed a time period.
And after the difference between the current value and the system time difference does not exceed a time period, judging whether the difference between the current value and the system time difference exceeds a second preset range. For example, the second preset range is also preset to be a half time period, and whether the difference between the current value and the system time difference exceeds the half time period is judged. It should be noted that the second preset range may be the same as the first preset range, or may be different from the first preset range, and the specific value of the second preset range is not limited in this embodiment.
And if the difference between the current value and the system time difference does not exceed a second preset range, finishing the coding error correction processing. If the difference between the current value and the system time difference exceeds a second preset range, a self time coding value is added, and the coding error correction processing is finished.
According to the scheme provided by the embodiment, the corresponding number of time code values are supplemented according to the difference between the current value and the system time difference of the system clock corresponding to the current reading operation and the system clock corresponding to the last reading operation, so that the discarded key values are accurately supplemented, and the decoding reliability of the infrared remote control is further improved.
The present invention also provides a computer-readable storage medium storing a decoding processing program of an infrared remote control, the decoding processing program of the infrared remote control being executable by one or more processors to:
reading the current value of a register corresponding to the infrared remote control;
acquiring a system time difference between a system clock corresponding to the current reading operation and a system clock corresponding to the last reading operation;
identifying whether coding errors occur or not according to the current value and the system time difference;
if yes, carrying out coding error correction processing;
and after the coding and error correction processing is finished, coding and decoding processing is carried out.
Further, when executed by the processor, the decoding processing program of the infrared remote control further implements the following operations:
comparing whether the difference between the current value and the system time difference exceeds a first preset range or not;
if yes, identifying that coding errors occur;
if not, identifying that no coding error occurs.
Further, when executed by the processor, the decoding processing program of the infrared remote control further implements the following operations:
-supplementing a corresponding number of time-coded values depending on the difference between said current value and said system time difference.

recording and storing a system clock corresponding to the current reading operation;
acquiring a system clock corresponding to the stored last reading operation;
and calculating the system time difference between the system clock corresponding to the current reading operation and the system clock corresponding to the last reading operation.

if the current value is invalid, detecting whether the reading of the register is overtime;
if the reading time is over, the operation is ended
