Description

TECHNICAL FIELD

[0001] The present application relates to the field of data transmission, in particular to a channel crosstalk detection method and system based on a time-division multiplexing mechanism and a medium. BACKGROUND

[0002] In a conventional case, audio data transmission between two terminals is mainly realized based on two chips, and audio transmission between the two chips usually uses an Inter-IC Sound (I2S) bus or a Time-division Multiplexing (TDM) communication mode. In the I2S or TDM audio transmission process, audio data transmission errors may occur due to some factors (external factors / chip abnormalities / software defects, etc.), thereby causing some audio problems. For example, in TDM communication between two chips, TDM adopts an 8-channel configuration, and channel 1 to channel 8 sequentially transmit 1 audio data respectively, A and a use channel 1 to transmit audio data for communication, B and b use channel 2 to transmit audio data for communication, if crosstalk occurs between channel 1 and channel 2 (i.e., the data of channel 1 and channel 2 are reversed), A and a may hear the voice of b while communicating, and cannot hear the voice of a, which will bring a very poor communication experience to the customer. Therefore, a TDM data transmission crosstalk self-detection mechanism is particularly important, and an accurate TDM data transmission crosstalk self-detection mechanism can help software developers to repair software defects or add corresponding abnormal self-recovery mechanisms as early as possible.

[0003] At present, in order to confirm the accuracy of data transmission, cyclic redundancy check (CRC) is usually performed on the transmitted data, the data packet header carries data CRC information, and the opposite chip calculates CRC after receiving the data to confirm whether the data transmission is incorrect. However, this method can only confirm whether the data frame is incorrect, and cannot help software developers to further locate the specific reasons and rules of data transmission errors, and has certain limitations. SUMMARY

[0004] The present application provides a channel crosstalk detection method, system and medium based on a time-division multiplexing mechanism, which detects the crosstalk of the channel based on the change of the channel verification data of each channel in each data frame before and after data transmission.

[0005] To solve the above technical problems, the present application provides a channel crosstalk detection method based on a time-division multiplexing mechanism, comprising:

[0006] The first data of each channel at different data transmission time points is acquired based on a time division multiplexing mechanism, and each channel is traversed to form to-be-transmitted data of the current channel at each data transmission time point according to the first data of the current channel at each data transmission time point and first channel verification data of the current channel at each data transmission time point, wherein the first channel verification data and the first data correspond to each other in a one-to-one manner.

[0007] All the to-be-transmitted data at the same data transmission time point are taken as a to-be-transmitted data frame, and then each to-be-transmitted data frame is sequentially transmitted to a data receiving end through each channel according to each data transmission time point, and a to-be-detected data frame received by the data receiving end is acquired, wherein the to-be-detected data frame includes a plurality of second channel verification data.

[0008] Each data transmission time point is traversed, and a channel crosstalk detection result is analyzed according to all the second channel verification data in the to-be-detected data frame received by the data receiving end at the current time point and all the second channel verification data in the to-be-detected data frame received by the data receiving end at the previous time point.

[0009] In the embodiment of the present application, before data transmission by using a time division multiplexing technology, each channel is traversed, to-be-transmitted data of the current channel at different data transmission time points is formed according to the first data of the current channel at different data transmission time points and first channel verification data of the current channel at different data transmission time points, and all the to-be-transmitted data at the same data transmission time point are taken as a to-be-transmitted data frame, so that each first data in the to-be-transmitted data frame has corresponding channel verification data, and therefore, after the to-be-transmitted data frame is transmitted to a data receiving end, whether crosstalk occurs in each channel can be analyzed according to all the second channel verification data in the to-be-detected data frame received by the data receiving end at different time points, so that the cause of an error can be determined when data transmission is incorrect, and real-time and accurate channel crosstalk detection is realized.

[0013] According to the difference between each second channel check data in the to-be-detected data frame received by the data receiving end at the current moment and each second channel check data in the to-be-detected data frame received by the data receiving end at the previous moment in the same channel, the channel number of the channel in which crosstalk occurs in the current transmission process and other specific crosstalk conditions can be determined, so that subsequent data tracing or repair management can be performed.

[0014] As a preferred solution, the channel crosstalk detection method based on the time division multiplexing mechanism further comprises:

[0016] According to the channel number of the channel in which crosstalk occurs, the administrator or software developer can clearly master the data transmission crosstalk condition and locate and analyze the crosstalk problem, so that software defects can be repaired in time through the background management terminal, or a software abnormal self-repairing mechanism can be added according to the channel number of the channel in which crosstalk occurs, so as to ensure that the customer experience is not affected.

[0017] As a preferred solution, the time division multiplexing mechanism is used to obtain first data of the current channel at different data transmission moments, and each channel is traversed, and the first data of the current channel at each data transmission moment and the first channel check data of the current channel at each data transmission moment are used to form to-be-transmitted data of the current channel at each data transmission moment, and the to-be-transmitted data of the current channel at each data transmission moment is specifically:

[0041] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0042] Embodiment one:

[0043] Please refer to Figure 1 A channel crosstalk detection method based on a time-division multiplexing mechanism is provided in the embodiments of the present application, which comprises steps S1 to S4, and each step is specifically as follows:

[0044] In step S1, based on the time-division multiplexing mechanism, the first data of each channel at different data transmission time is obtained, and each channel is traversed. According to the first data of the current channel at each data transmission time and the first channel verification data of the current channel at each data transmission time, the to-be-transmitted data of the current channel at each data transmission time is formed. The first channel verification data and the first data correspond to each other.

[0045] It should be noted that the time-division multiplexing technology (Time-division Multiplexing, TDM) is a communication technology that different signals are interleaved in different time periods, transmitted along the same channel, and then restored to the original signal by extracting the signals in each time period at the data / signal receiving end.

[0046] In this embodiment, in the time-division multiplexing mechanism, the transmission configuration of the data is 8 channels, and the capacity of each channel is 32 bits, that is, the maximum data amount that each channel can transmit is 32 bits. Even if a channel has no audio data or other to-be-transmitted data, the channel can also transmit empty data. Therefore, the maximum data amount that each to-be-transmitted data frame can transmit in the TDM transmission process is 32*8=256 bits. Please refer to Figure 2 The high 8 bits (the first 8 bits) of each channel are used to transmit the first channel verification data, and the low 24 bits (the last 24 bits) are used to transmit the audio data (i.e., the first data). The data amount used to transmit the channel verification data can be adjusted according to the actual bandwidth application situation, and it is not necessarily set to 8 bits.

[0047] As a preferred solution, step S1 comprises steps S11 to S13, and each step is specifically as follows:

[0048] In step S11, based on the time-division multiplexing mechanism, the first data of each channel at different data transmission time is obtained.

[0049] In this embodiment, please refer to Figure 3 ,In the time division multiplexing mechanism, data transmission is configured as 8 channels, namely Ch1 to Ch8.

[0050] Step S12, please refer to Figure 3 , obtain the channel number of each channel, and determine the transmission order of each data frame to be transmitted according to each data transmission time, and determine the frame number of the data frame to be transmitted corresponding to each data transmission time based on the transmission order. Therefore, the data frames to be transmitted with the same frame number are at the same data transmission time.

[0051] Step S13, traverse each first data corresponding to each channel, multiply the frame number of the data frame to be transmitted corresponding to the data transmission moment corresponding to the current first data and the channel number of the channel where the current first data is located, and use the product result as the first channel verification data of the current channel at each data transmission moment, and then add the first channel verification data corresponding to the current first data in front of the current first data to form the data to be transmitted of the current channel at each data transmission moment.

[0052] As an example, see Figure 3 , sorted according to the time sequence of each data transmission moment, the data transmission moment corresponds to the data frame to be transmitted with frame number (ie, the data frame to be transmitted of the 3rd frame), so the first channel check data of channel Ch2 at the data transmission moment is.

[0053] In step S2, all data to be transmitted at the same data transmission moment are regarded as data frames to be transmitted, and then each data frame to be transmitted is transmitted to the data receiving end through each channel in turn according to each data transmission moment, and the data frame to be detected received by the data receiving end is obtained; wherein the data frame to be detected includes multiple second channel verification data.

[0054] In this embodiment, the smaller the frame number of the data frame to be detected is, the earlier the data transmitting end transmits the data frame to be detected to the data receiving end.

[0055] It should be noted that the data transmitter and the data receiver can be chips. For example, chip A acts as the data transmitter and sends frame data to chip B. When the roles of the two chips are reversed, that is, chip B sends frame data to chip A, chip B acts as the data transmitter and chip A acts as the data receiver, and the channel crosstalk detection method described in Embodiment 1 of the present invention can also be implemented.

[0056] Step S3: traversing each data transmission moment, analyzing the crosstalk detection result according to all the second channel check data in the to-be-detected data frame received by the data receiving end at the current moment and all the second channel check data in the to-be-detected data frame received by the data receiving end at the previous moment.

[0057] As a preferred solution, step S3 comprises steps S31 to S33, each of which is specifically as follows:

[0058] Step S31: traversing each data transmission moment, obtaining all the second channel check data in the to-be-detected data frame received by the data receiving end at the current moment and all the second channel check data in the to-be-detected data frame received by the data receiving end at the previous moment.

[0059] Step S32: subtracting each second channel check data in the to-be-detected data frame received by the data receiving end at the previous moment from each second channel check data in the to-be-detected data frame received by the data receiving end at the current moment to obtain the check data difference value corresponding to each channel.

[0060] As an example, the second channel check data and the check data difference value of each channel of the first frame and the second frame are shown in Table 1.

[0061] Table 1: Check data difference value of each channel of the first frame and the second frame

[0062] Channel number Ch1 Ch2 Ch3 Ch4 Ch5 Ch6 Ch7 Ch8 Second channel check data of the 1st frame 1 2 3 4 5 6 7 8 Second channel check data of the 2nd frame 2 4 6 8 10 12 14 16 Difference of check data between the 1st and 2nd frames 1 2 3 4 5 6 7 8

[0063] Since the check data difference value of the first frame and the second frame is consistent with the channel number of the corresponding channel, it indicates that the data transmission process between the first frame and the second frame is normal.

[0064] Step S33: traversing each check data difference value, if the current check data difference value is inconsistent with the channel number of the channel corresponding to the current check data difference value, determining the channel number of the channel in which crosstalk occurs according to the current check data difference value as the crosstalk detection result.

[0065] In this embodiment, please refer to Figure 4 , the specific situation of each second channel check data in the to-be-detected data frame received by the data receiving end at different moments can be seen. Among them, the second channel check data of Ch3 and Ch4 is obviously abnormal. Taking the second channel check data of each channel of the second frame and the third frame as an example, please refer to Table 2, at this time, the check data difference value of Ch3 is 4, and the check data difference value of Ch4 is 3, which indicates that the data of Ch3 and Ch4 has crosstalk.

[0066] Table 2: Check data difference value of each channel of the second frame and the third frame

[0067] Channel number Ch1 Ch2 Ch3 Ch4 Ch5 Ch6 Ch7 Ch8 Second channel check data of the 2nd frame 2 4 8 6 10 12 14 16 Second channel check data of the 3rd frame 3 6 12 9 15 18 21 24 Difference of check data between the 2nd and 3rd frames 1 2 4 3 5 6 7 8

[0068] As a preferred solution, after the step S33 is executed, a transmission repair procedure is further included, which comprises the step S4, which is specifically as follows:

[0069] In step S4, each check data difference is traversed, and if the current check data difference is inconsistent with the channel number of the channel corresponding to the current check data difference, the channel number of the channel where crosstalk occurs is determined according to the current check data difference, and the channel number of the channel where crosstalk occurs is fed back to the background management terminal in real time, and then the data transmission process is repaired based on the channel number of the channel where crosstalk occurs through the background management terminal, so as to ensure that the user experience is not affected.

[0089] Compared with the prior art, the embodiment of the application has the following beneficial effects:

[0090] The application provides a channel crosstalk detection method and system based on a time division multiplexing mechanism and a medium. Before data transmission by using a time division multiplexing technology, each channel is traversed, first data of a current channel at different data transmission moments and first channel verification data of the current channel at the different data transmission moments are used to form to-be-transmitted data of the current channel at the different data transmission moments, and all to-be-transmitted data at a same data transmission moment are used as a to-be-transmitted data frame, so that each first data in the to-be-transmitted data frame has one-to-one corresponding channel verification data. Therefore, after the to-be-transmitted data frame is transmitted to a data receiving end, all second channel verification data of a to-be-detected data frame received by the data receiving end at different moments can be used to analyze whether crosstalk occurs in each channel, so that a cause of an error can be determined when data transmission is incorrect, and real-time and accurate channel crosstalk detection is achieved.

[0091] Further, according to a transmission sequence of each to-be-transmitted data frame determined by a data transmission moment, a frame number of a to-be-transmitted data frame corresponding to each data transmission moment is determined, each first data is traversed, a product of a frame number of a to-be-transmitted data frame corresponding to a data transmission moment corresponding to the current first data and a channel number of a channel in which the current first data is located is used as channel verification data corresponding to the current first data, so that a difference value of each channel verification data of to-be-transmitted data frames of adjacent transmission moments is always equal to a channel number of a channel in which the channel verification data is located.
