s104, generating a signal source parameter table according to the first signal source real-time gain value and the second signal source real-time gain value, and sending the signal source parameter table.
To better illustrate the concept of a signal source channel sound sensitivity adjustment method based on power protection feedback, further, for example:
step S101, an output audio instruction is sent to the test equipment, so that the test equipment outputs the prefabricated reference sound source data and the power over-protection data.
Step S102, generating a switching signal source instruction according to the prefabricated reference sound source data and the power over-protection data.
Specifically, the power over-protection data includes a first rated power value and a second rated power value.
It should be noted that, the main control module is a built-in CPU of the television, and the staff can input the signal source information into the test device, and the test device outputs the prefabricated reference sound source data and the power over-protection data to the television, where the prefabricated reference sound source data includes HDMI signal source data, TV signal source data, AV signal source data, and the like, for example, according to the actual production standard, the state information with a sine wave of 1kHz is selected for making, the amplitude uses 500mV as the standard, the modulation degree of the TV signal source data is 54%, the AV signal source data is 500mV, and the HDMI signal source data is an audio file of-12 dB. Further, the main control module generates a signal source switching instruction according to the data type of the prefabricated reference sound source data so as to adjust the signal source corresponding to the television.
It should be noted that, the power over-protection data includes a first rated power value and a second rated power value, where the first rated power value is a protection point of the over-power set by the power amplifier, and the second rated power value is a protection point of the under-power set by the power amplifier.
Step S103, generating an instruction for increasing the audio gain and an instruction for decreasing the audio gain according to the preset amplifying multiple value, respectively executing the instruction for increasing the audio gain and the instruction for decreasing the audio gain, and generating a first signal source real-time gain value and a second signal source real-time gain value.
Specifically, the preset power amplification magnification value is the power amplification magnification.
More specifically, in the step of generating an instruction for increasing audio gain and an instruction for decreasing audio gain according to audio data and a preset power amplification multiple value, the instruction for increasing audio gain and the instruction for decreasing audio gain are executed respectively, and the steps of generating a first signal source real-time gain value and a second signal source real-time gain value specifically include the following steps:
executing an instruction for improving the audio gain, generating first preprocessing power detection data, comparing the first preprocessing power detection data with a first rated power value, generating abnormal feedback information if the first preprocessing power detection data is larger than the first rated power value, and generating a first signal source real-time gain value.
Specifically, in the step, according to the audio data and the preset power amplification multiple value, an audio gain increasing instruction and an audio gain decreasing instruction are generated, the audio gain increasing instruction and the audio gain decreasing instruction are executed respectively, and the steps of generating a first signal source real-time gain value and a second signal source real-time gain value specifically include the following steps:
executing the instruction for reducing the audio gain to generate second preprocessing power detection data, comparing the second preprocessing power detection data with a second rated power value, and generating error feedback information and generating a second signal source real-time gain value if the second preprocessing power detection data is larger than the second rated power value.
It should be noted that the preset power amplification magnification value is a power amplification magnification. The total power of the sound output of the television according to the formula is equal to the product of the audio source sound reference, the audio gain value of the signal source and the amplification factor of the power amplifier, wherein the audio source sound reference is not prefabricated with reference sound source data, and the audio gain value of the signal source is a first signal source real-time gain value or a second signal source real-time gain value. When the amplification factor of the power amplifier is certain, and according to the prefabricated reference sound source data, if the consistent output power of each signal source is required, only the gain value is required to be adjusted. For example: the testing equipment inputs the data of the prefabricated reference sound source into the television, the main control module generates an instruction for increasing the audio gain, the main control module is increased by 0.5dB each time for 15 seconds for detecting the power of the power amplifier until the output power is too high and exceeds the over-power protection point set by the power amplifier, the gain value under the state of the signal source, namely the real-time gain value of the first signal source, is recorded, further, the main control module generates an instruction for reducing the audio gain, the television automatically reduces the sound gain value of the current signal source, the main control module is reduced by 0.5dB each time for 15 seconds for detecting the power of the power amplifier until the output power is too low and is reduced to the under-power protection point set by the power amplifier, and the Offset value under the state of the signal source, namely the real-time gain value of the second signal source, is recorded.
Step S104, a signal source parameter table is generated according to the first signal source real-time gain value and the second signal source real-time gain value, and the signal source parameter table is sent.
It should be noted that, the main control module generates a signal source parameter table according to the first signal source real-time gain value and the second signal source real-time gain value, and sends the signal source parameter table so as to write the software code later. For example, the signal source state, the first signal source real-time gain value and the second signal real-time gain value are summarized and stored.
Further, in one embodiment, the step of generating the switching signal source command according to the pre-fabricated reference sound source data and the power over-protection data specifically includes the following steps:
generating a playing instruction to judge whether the prefabricated reference sound source data can be played normally, and if not, generating error alarm information.
It should be noted that, the television will play the prefabricated reference audio data, if play abnormality occurs, an error alarm message will be generated to prompt the staff to process the prefabricated reference audio data or overhaul the power amplifier.
In this way, according to the signal source channel sound sensitivity adjustment method based on power protection feedback, firstly, the standard of the sound of the audio source, namely the prefabricated standard sound source data, is established, so that the audio information of various audio formats of the signal sources of all channels are consistent, then the main control module compares the audio data of all the signal sources with the power over-protection data by utilizing the over-protection mechanism of the power over-protection data, namely the power over-protection data, so as to obtain the real-time gain value of the signal sources, and therefore, the sound output power of all the signal sources is consistent, and further, the phenomenon that the television has sound negligence when the signal sources are converted is avoided.
Referring to fig. 2, a signal source channel sound sensitivity adjustment system based on power protection feedback includes: the device comprises a sending module, a reading module and an executing module. The sending module is used for sending an output audio instruction to the testing equipment so that the testing equipment outputs the prefabricated reference sound source data and the power over-protection data; the sending module is further used for generating a signal source parameter table according to the first signal source real-time gain value and the second signal source real-time gain value and sending the signal source parameter table; the reading module is used for generating a signal source switching instruction according to the prefabricated reference sound source data and the power over-protection data and receiving the audio data; executing the instruction for increasing the audio gain and the instruction for decreasing the audio gain, and generating a first signal source real-time gain value and a second signal source real-time gain value.
Further, in an embodiment, the execution module is further configured to execute the instruction for increasing the audio gain, generate first preprocessed power detection data, compare the first preprocessed power detection data with the first rated power value, and if the first preprocessed power detection data is greater than the first rated power value, generate abnormal feedback information, and generate the first signal source real-time gain value.
It should be noted that, the main control module includes a sending module, a reading module and an executing module, so as to execute the signal source channel sound sensitivity adjusting method based on the power protection feedback in this embodiment.
Further, in another embodiment, a play command is generated in the step to determine whether the pre-fabricated reference audio source data can be played normally, and if not, an error alarm message is generated, which specifically further includes the following steps: s102a, generating a picture display detection instruction and executing the picture display detection instruction; s102b, judging whether the signal source display is abnormal, if so, generating a video signal polling instruction, and sending the video signal polling instruction to test equipment, and if not, generating error alarm information; s102c, receiving feedback information. It should be noted that, the prefabricated reference audio source data includes sound signal data and video signal data, when the television cannot normally play the video signal of the signal source, the main control module will generate a picture display detection instruction to determine whether the display of the signal source is abnormal, if so, a video signal polling instruction will be generated and sent to the test equipment, after the test equipment receives the video signal polling instruction, the signal source is switched by automatic polling until the display is normal, this way is used for solving the situation that the format of the video signal data may not match the format of the video signal data playable by the signal source, when the signal source is more, the detection efficiency can be improved by adopting the above way, and no extra manpower is needed to be input to maintain and monitor. Meanwhile, the detection process can be more automated by adopting the mode.
Further, when the television is able to normally display the video picture, if the playing of the sound signal is abnormal, for example: s102d, generating a sound detection instruction and executing the sound detection instruction; s102e, judging whether the sound played by the signal source is abnormal, if so, generating a sound signal polling instruction, and sending the sound signal polling instruction to test equipment, and if not, generating error alarm information; s102c, receiving the processing information. It should be noted that, when the video signal of the television signal source can be normally played and the sound signal cannot be played, the main control module generates a sound detection instruction to determine whether the playing sound of the signal source is abnormal, if yes, a sound signal polling instruction is generated and sent to the test equipment, and after the test equipment receives the sound signal polling instruction, the test equipment switches the mode of the prefabricated audio data through automatic polling until the sound is normal. Meanwhile, the detection process can be more automated by adopting the mode.
