Description

一种数据传输方法、装置、电子设备和存储介质 技术领域
本申请涉及一种音频领域，并具体公开了一种数据传输方法、装置、电子设备和存储介质。
背景技术
随着汽车电子电气化迅速发展，汽车的智能化、互联网化也越来越受到车载领域开发的重视。汽车智能座舱域控制器系统作为驾驶舱内与人交互最多的电子单元，从单一的信息娱乐系统发展到如今的集成仪表、中控娱乐、驾驶员监控以及智能语音助手等复杂功能于一体，其承载的人机交互能力满足当今汽车智能化，互联网化的需求，人机交互接口及语音传输数量需求骤增。
智能座舱系统语音交互接口如麦克风的需求，已从过去的单麦克风满足通话要求演进到如今四路(或更多)麦克风输入，来满足通话，语音识别，消音消躁等复杂的语音交互功能需求。丰富的语音接口配合强大的片上系统(System on Chip，SOC)芯片，可以实现语音助手管家，导航、TTS、音效，声场控制等功能，这些丰富的音频功能对整个智能座舱系统内部的音频传输能力，提出了新的要求。
传统的智能座舱系统架构中，每一个麦克风输入设备分别通过一个音频接口与SOC芯片连接，来实现将麦克风输入设备采集的音频数据传输给SOC芯片。麦克风输入设备的增加导致音频接口数量也随之增加，而SOC芯片的尺寸固定，因此SOC芯片中用于接收数据的管脚数量有限，若想接收到所有麦克风输入设备采集的数据，需要减少其它功能接口的数量，影响SOC芯片上其它功能的实现。
目前为了解决这一问题，增加了数字信号处理(Digital Signal Process，DSP)芯片，DSP芯片获取多有麦克风输入设备采用的音频数据，并将每一个音频数据通过音频接口中的一个音频传输通道进行传输，实现音频接口复用来减少对音频接口数量的需要。实际使用时，由于多个麦克风输入设备的采集深度不同导致多个麦克风输入设备采集的音频数据的长度不同，而数据传输通道的带宽固定，在麦克风输入设备采集的音频数据的长度小于数据传输通道的带宽时，将会造成传输资源的浪费，降低传输效率。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，在本申请的描述中“至少一个”是指一个或多个，其中，多个是指两个或两个以上。鉴于此，本发明实施例中也可以将“多个”理解为“至少两个”。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
需要指出的是，本申请实施例中“连接”指的是电连接，两个电学元件连接可以是两个电学元件之间的直接或间接连接。例如，A与B连接，既可以是A与B直接连接，也可以是A与B之间通过一个或多个其它电学元件间接连接，例如A与B连接，也可以是A与C直接连接，C与B直接连接，A与B之间通过C实现了连接。
本申请实施例提供的数据传输方法以及数据接收方法可以应用于汽车的智能座舱系统中，参见图1，为本申请实施例提供的一种汽车的智能座舱系统的架构示意图。如图1所示，该智能座舱系统主要包括：多个音频采集设备(图1中以8个为例)和用于对音频采集设备采集的音频数据进行处理的SOC芯片。其中，SOC芯片连接的音频设备可以包括4个用于获取用户的语音数据的第一类型音频采集设备，4个用于获取音频播放设备播放的音频的第二类型音频采集设备。其中，SOC芯片获取第二类型音频采集设备采集的音频数据，并基于获取的音频数据对音频播放设备播放的音频进行回音处理。
应理解，本申请实施例提供的智能座舱系统中还包括可以其它类型的音频采集设备，用于实现其它功能。
其中，多个音频采集设备以及SOC芯片通过多个数据传输接口连接。其中，每个音频采集设备通过对应的数据传输接口与SOC芯片连接。
采用图1所示的数据传输接口将采集的音频数据传输给SOC芯片时，每一个音频采集设备均需要配置一个不同的数据传输接口，SOC芯片也需要配置与音频采集设备相同数量的管脚，该管脚与数据传输接口连接以获取智能座舱系统中所有音频采集设备采集的音频数据。采用上述音频数据传输方式，在SOC芯片的管脚数量固定的情况下，若想获取到所 有音频采集设备采集的音频数据，则需要减少SOC芯片其它管脚的数量，可能会导致智能座舱系统其它功能的实现。
基于上述情况，提供了数据传输接口复用的方案，如图2所示，每一个数据传输接口中包括三个接口，分别是传输时钟接口，同步时钟接口以及数据接口。每一个数据接口中可以包括至少两个数据传输通道，为了实现数据传输接口复用，在SOC芯片与音频采集设置之间设置一个DSP芯片。如图3所示，该DSP芯片上设置有多个数据采集接口和多个数据传输接口，多个数据采集接口与多个音频采集设备一对一对应连接，DSP芯片通过多个数据传输接口与SOC芯片连接，DSP芯片可以采用上述多个数据采集接口获取多个音频采集设备采集的音频数据，并将采集的每一个音频数据通过数据传输接口的一个数据传输通道传输给SOC芯片。需要说明的是，上述数据采集接口和数据传输接口可以是相同类型的接口，也可以是不同类型的接口。例如，
实际使用时，每一个数据采集装置采集的音频数据的长度可能不同，而数据传输接口中包含的每一个数据传输通道的带宽相同，当该数据传输通道中传输的音频数据的长度小于数据传输通道的带宽时，则会造成该数据传输通道的传输资源浪费，以及降低了数据传输效率。
上述介绍了智能座舱系统中设置的数据传输接口存在传输资源浪费，数据传输效率低的问题。为解决上述问题，本申请实施例提供一种数据传输方法，该方法可以实现将多个音频采集设备采集的音频数据通过一个数据传输通道进行传输，实现一个对多的形式进行数据传输，从而提升了数据传输效率，并有利于减少智能座舱系统中数据传输接口的数量。
参见图4，为本申请实施例提供的一种数据传输方法的示意图，该方法的执行主体可以是发送设备，该发送设备可以是上述智能座舱系统中的DSP芯片，该DSP芯片可以包括多个数据采集接口和至少一个数据传输接口，至少一个数据传输接口中的每个数据传输通道构成至少两个数据传输通道，多个音频采集接口用于与对应的音频采集设备连接。
具体实现时，该数据传输方法可以包括以下步骤：
步骤401：发送设备通过多个数据采集接口获取对应的音频采集设备采集到的音频数据。
步骤402：发送设备将获取到的音频数据中音频数据的长度小于第一阈值的音频数据，进行叠加得到至少一个数据组合。需要说明的是，本申请实施例提供的音频数据的长度是指存储该音频数据所占用的字节数。
其中，至少一个数据组合中的每个数据组合中包括至少两个音频采集设备采集到的音频数据、且每个数据组合的长度小于或等于第一阈值。其中，每个数据组合的长度为该数据组合叠加的音频数据的长度的总和。
其中，该第一阈值为数据传输通道的带宽。其中，发送设备叠加得到的至少一个数据组合的数量需要小于或等于多个数据传输通道的数量。基于上述方案，发送设备可以为数据组合以及数据传输通道分配序号，数据组合的序号和数据传输通道的序号一对一，则可以将数据组合通过对应序号的数据传输通道进行传输，如此，数据组合按照固定的数据传输通道传输，保证发送设备可以传输全部的数据组合，以及后续设备在接收该数据组合时，可以准确的识别该数据组合中包含的音频数据。
作为一种可能实现的方式，在上述步骤402中，DSP芯片可以设置数据组合序号与传输通道序号之间的对应关系，在传输数据组合时，首先获取每个数据组合的序号，并根据 每个数据组合的序号从上述对应关系中找到该数据组合对应的数据传输通道的序号，并将该数据组合通过对应的数据传输通道进行传输。
在叠加数据组合以及确定数据组合序号和数据传输通道序号的对应关系之后，发送设备可以对上述至少一个数据组合进行传输，具体可以参见步骤403。
步骤403：发送设备将每个数据组合通过多个数据传输通道中的一个数据传输通道发出。
作为一种可能实现的方式，若至少一个数据组合的数量大于1，为了进一步的提升系统的传输效率以及减少传输时间，用于发出至少一个数据组合中的任意两个数据组合的数据传输通道不相同。
作为一种可能实现的方式，在部分数据传输通道损坏的情况下或者为了进一步提升数据传输通道复用程度，可以将部分或全部数据组合依次通过一个数据传输进行传输，即在确定当前数据组合传输完毕后，将下一个数据组合继续通过该数据传输通道进行传输，直至传输完所有的数据组合。
需要说明的是，发送设备可以将获取到的音频数据中音频数据的长度等于第一阈值的音频数据，发送设备可以通过多个数据传输通道中用于传输至少一个数据组合外的数据传输通道发出。
通过上述步骤401～步骤403提供的方案，可以将数据长度小于数据传输通道带宽的音频数据进行叠加，得到至少一个数据组合，并将至少一个数据组合中的每个数据组合通过一个数据传输通道进行传输，实现了一个数据传输通道对应多个音频采集设备，即实现数据传输通道复用，进一步减少了数据传输通道的数量，有利于进一步减少发送设备与接收设备之间的数据传输接口的数量。
应理解，由于每个数据组合中叠加有至少两个音频采集设备采集的音频数据，因此，单个数据组合的长度要大于单个音频数据的长度，采用上述传输方式传输数据组合时，有利于更有效的占用传输资源，从而实现提升数据传输效率。
需要说明的是，发送设备能够将至少一个数据组合中的每个数据组合通过一个数据传输通道进行发出的前提是音频数据叠加完毕。实际使用时，发送设备是基于预先设置的叠加规则，将获取到的音频数据中音频数据的长度小于第一阈值的音频数据进行叠加，得到至少一个数据组合。其中，叠加规则是根据每一个音频采集设备的采集深度设置的。其中，叠加规则中包括音频数据的叠加顺序以及被叠加的音频数据的长度。
作为一种可能实现方式，发送设备在进行数据传输之前会接收连接的接收设备发送的第一控制指令，该第一控制指令中包含用于调整发送设备连接的多个音频采集设备的采集深度的第一目标参数，发送设备接收到该第一控制指令后，并将该第一控制指令分别通过多个数据采集接口输出给各个音频采集设备，同时发送设备基于第一目标参数预先计算各个音频采集设备在控制指令控制下输出的音频数据的长度，发送设备根据预先计算的音频数据的长度设置叠加规则。
在一示例中，发送设备接收到叠加规则后，设置数据组合序号和数据传输通道序号之间的对应关系，并将上述对应关系以及叠加规则发送给接收设备。其中，发送设备和接收设备可以通过发送设备上的多个数据传输通道实现连接。其中，该叠加规则中包含音频数据的叠加顺序以及被叠加的音频数据的长度。
具体地，发送设备通过数据采集接口采集到对应的音频数据采集的音频数据之后，利 用叠加规则，将音频数据按照叠加规则中的叠加顺序将音频数据依次叠加，得到至少一个数据组合。
应理解，采用上述方案可以将叠加规则以及上述对应关系发送给接收设备，接收设备在后期接收到发送设备发送的数据组合时，可以确定是否接收到完整的数据，以及准确的对获取的数据组合进行识别，提升传输准确度。
在一示例中，第一控制指令中包含多个子控制指令，多个子控制指令与多个音频采集设备一对一，每一个子控制指令用于调整对应的音频采集设备的采集深度，发送设备在接收到接收设备发送的第一控制指令后，将每个子控制指令通过数据音频采集接口发送给对应的音频采集设备中。
作为另一种可能实现的方式中，发送设备在进行数据传输之前，接收来自接收设备的第二控制指令以及叠加规则，该第二控制指令中包含用于调整发送设备连接的多个音频采集设备的采集深度的第二目标参数，发送设备接收到该第二控制指令后，并将该第二控制指令分别通过多个数据采集接口输出给对应的各个音频采集设备。
在一示例中，发送设备接收连接的接收发送的第二控制指令、叠加规则以及数据组合序号和数据传输通道序号之间的对应关系。
下面，结合以下实施例对音频数据叠加为数据组合的过程进行说明。
场景1：参见图5所示，智能座舱系统中包含8个音频采集设备，每一个音频采集设备的采集深度为2，即音频采集设备采集的音频数据的长度均为16比特(binary digit，bit)，SOC芯片与DSP芯片之间存在两个数据传输接口，每一个数据传输接口中包含两个数据传输通道，而每一个数据传输通道的带宽为32bit。
如图6所示，发送设备在接收到音频采集设备1至8的采集的音频数据之后，发送设备将音频采集设备1至2采集的音频数据直接叠加为数据组合1，将音频采集设备3至4采集的音频数据直接叠加为数据组合2，将音频采集设备5至6采集的音频数据直接叠加为数据组合3，将音频采集设备7至8采集的音频数据直接叠加为数据组合4，通过序号为1的数据传输通道传输数据组合1，通过序号为2的数据传输通道传输数据组合2，通过序号为3的数据传输通道传输数据组合3，通过序号为4的数据传输通道传输数据组合4。其中，序号为1和2的数据传输通道构成数据传输接口1，序号为3和4的数据传输通道构成数据传输接口2。
采用上述方案，每一个数据组合的长度为数据传输通道的带宽，可以采用一个数据传输通道进行传输，实现了单个数据传输通道传输两个音频采集设备采集的音频数据，因此，可以在满足传输需求的同时，提升传输效率，且由于采用了数据传输通道复用，可以减少一半的数据传输通道的数量，在音频采集设备数量较多时，有利于进一步减少连接在发送设备和接收设备之间的数据传输接口的数量。
场景二：参见图7所示，智能座舱系统中包含8个音频采集设备，音频采集设备1至4的采集深度为1，音频采集设备5至8的采集深度为3，即音频采集设备1至4采集的音频数据长度均为8bit，音频采集设备1至4采集的音频数据长度均为24bit，SOC芯片与DSP芯片之间存在两个数据传输接口，每一个数据传输接口中包含两个数据传输通道，而每一个数据传输通道的带宽为32bit。
如图8所示，发送设备在接收到音频采集设备1至8的采集的音频数据之后，发送设备将音频采集设备1和音频采集设备5采集的音频数据直接叠加为数据组合1，将音频采 集设备2和音频采集设备6采集的音频数据直接叠加为数据组合2，将音频采集设备3和音频采集设备7采集的音频数据直接叠加为数据组合3，将音频采集设备4和音频采集设备8采集的音频数据直接叠加为数据组合4，通过序号为1的数据传输通道传输数据组合1，通过序号为2的数据传输通道传输数据组合2，通过序号为3的数据传输通道传输数据组合3，通过序号为4的数据传输通道传输数据组合4。其中，序号为1和2的数据传输通道构成数据传输接口1，序号为3和4的数据传输通道构成数据传输接口2。
采用上述方案，每一个数据组合的长度正好为数据传输通道的带宽，可以采用一个数据传输通道进行传输，实现了单个数据传输通道传输两个音频采集设备采集的音频数据，因此，可以在满足传输需求的同时，提升传输效率，且由于采用了数据传输通道复用，可以减少一半的数据传输通道的数量，在音频采集设备数量较多时，有利于进一步减少连接在发送设备和接收设备之间的数据传输接口的数量。
场景三：参见图9所示，智能座舱系统中包含8个音频采集设备，音频采集设备1至8的采集深度均为1，即音频采集设备1至8采集的音频数据长度均为8bit，SOC芯片与DSP芯片之间存在两个数据传输接口，每一个数据传输接口中包含两个数据传输通道，而数据传输通道的带宽为32bit。
如图10所示，发送设备在接收到音频采集设备1至8的采集的音频数据之后，发送设备将音频采集设备1至4采集的音频数据直接叠加为一个数据组合1，将音频采集设备5至8采集的音频数据直接叠加为一个数据组合2，通过序号为1的数据传输通道传输数据组合1，通过序号为2的数据传输通道传输数据组合2。其中，序号为1和2的数据传输通道构成数据传输接口1，序号为3和4的数据传输通道构成数据传输接口2。
采用上述方案，每一个数据组合的长度正好为数据传输通道的带宽，可以实现单个数据传输通道传输四个音频采集设备采集的音频数据，因此，可以在满足传输需求的同时，提升传输效率，且由于采用了数据传输通道复用，可以减少四分之三的数据传输通道的数量，在音频采集设备数量较多的时，有利于进一步减少连接在发送设备和接收设备之间的数据传输接口的数量。
场景四：参见图11所示，智能座舱系统中包含8个音频采集设备，音频采集设备1至2的采集深度为1，音频采集设备3至7的采集深度为2，音频采集设备8的采集深度为4，即音频采集设备1至2采集的音频数据长度为8bit，音频采集设备3至7采集的音频数据长度均为16bit，音频采集设备8采集的音频数据长度为32bit，SOC芯片与DSP芯片之间存在两个数据传输接口，每一个数据传输接口中包含两个数据传输通道，而数据传输通道的带宽为32bit。
如图12所示，发送设备在接收到音频采集设备1至8的采集的音频数据之后，发送设备将音频采集设备1至3采集的音频数据直接叠加为数据组合1，将音频采集设备4至5采集的音频数据直接叠加为数据组合2，音频采集设备6至7采集的音频数据直接叠加为数据组合3。在叠加数据组合之后，通过序号为1的数据传输通道传输数据组合1，通过序号为2的数据传输通道传输数据组合2，通过序号为3的数据传输通道传输数据组合3，通过序号为4的数据传输通道直接传输音频采集设备8采集的音频数据。其中，序号为1和2的数据传输通道构成数据传输接口1，序号为3和4的数据传输通道构成数据传输接口2。
采用上述方案，每一个数据组合的长度正好为数据传输通道的带宽，可以实现单个数 据传输通道传输两个及以上音频采集设备采集的音频数据，因此，可以在满足传输需求的同时，提升传输效率，且由于采用了数据传输通道复用，在音频采集设备数量较多时，有利于进一步减少连接在发送设备和接收设备之间的数据传输接口的数量。
应理解，上述数据传输方案，也可以根据音频采集的采集深度的不同灵活的设置叠加规则，本申请这里不再做详细介绍。
参见图13，为本申请实施例提供的另一种数据传输方法的示意图，该方法的执行主体可以是接收设备，该接收设备可以上述智能座舱系统中的SOC芯片，该接收设备通过多个数据传输通道与发送设备连接，该方法包括以下步骤：
步骤1301：接收设备接收多个数据传输通道传输的至少一个数据组合。其中至少一个数据组合中的每个数据组合通过多个数据传输通道中的一个数据传输通道传输，每个数据组合中包括至少两个音频采集设备采集的音频数据。其中，音频采集设备通过对应的数据采集接口与发送设备连接。
步骤1302：接收设备对接收的至少一个数据组合进行拆分，得到多个音频采集设备采集的音频数据。
作为一种可能实现方式，接收设备在接收至少一个数据组合之前，先通过多个数据传输通道向发送设备发送第一控制指令，该第一控制指令中包含用于调整与发送设备连接的多个音频采集设备的采集深度的第一目标参数，并通过多个数据传输通道接收发送设备发送的叠加规则以及数据组合序号与数据传输通道序号之间的对应关系。其中，叠加规则是发送设备基于第一目标参数设置的。
作为另一种可能实现的方式，接收设备在接收至少一个数据组合之前，通过多个数据传输通道向发送设备发送第二控制指令以及叠加规则，其中，该第二控制指令用于调整与发送设备连接的多个音频采集设备的采集深度的第二目标参数，发送设备可以基于叠加规则对接收的音频数据进行叠加，构成至少一个数据组合。其中，叠加规则是接收设备基于第二目标参数设置的。
在一示例中，接收设备设置数据组合序号和数据传输通道序号之间的对应关系，并将上述对应关系通过多个数据传输通道向发送设备。
在另一示例中，接收设备通过多个数据传输通道接收发送设备发送的数据组合序号和数据传输通道序号之间的对应关系。
实际使用时，接收设备接收到至少一个数据组合后，先基于数据组合序号与数据传输通道序号的对应关系，确定每个数据组合的序号，从叠加规则中确定该数据组合中叠加的音频数据的顺序以及被叠加的每个音频数据的长度，并基于上述确定叠加的音频数据的顺序以及被叠加的音频数据的长度，对该数据组合进行拆分，得到多个音频数据。应理解，采用上述拆分方式可以对至少一个数据组合中的其它数据组合进行拆分，直至对至少一个数据组合拆分完毕。
下面，结合图2，对本申请实施例中的数据组合的拆分过程进行说明。
例如，如图2所示的数据传输通道Slot1接收到的数据组合，该数据组合的长度为32bit，利用数据组合序号与数据传输通道序号之间的对应关系，确定数据传输通道Slot1接收的数据组合的序号为1，利用上述叠加规则确定序号为1的数据组合中先叠加音频采集设备1采集的数据，再叠加音频采集设备2采集的音频数据，且两个被音频采集设备采集的音频数据的长度均为16bit，则对序号1的数据组合进行拆分时，序号为1的数据组合中前 16bit数据为音频采集设备1采集的音频数据，后16bit数据为音频采集设备2采集的音频数据。
在拆分数据组合得到所有音频采集设备采集的音频数据之后，接收设备可以对上述音频数据进行处理，具体可以参见步骤1303。
步骤1303：接收设备对拆分后的多个音频采集设备采集的音频数据进行处理。
在一示例中，接收设备还与多个音频播放设备连接，接收设备可以将第一类型音频采集设备采集的音频数据转换为语音，并发给该语音发送给多个音频播放设备后期播放，接收设备可以将第二类型的音频采集设备采集的音频数据进行预设处理，得到多个音频采集设备的调整参数，并将该调整参数输出给对应的音频播放设备。
通过上述步骤1301～步骤1303可以通过一个数据传输通道接收两个及两个以上音频采集设备采集的音频数据，接收设备连接的一个数据传输通道对应多个音频采集设备，实现了数据传输通道的复用，有利于减少SOC芯片管脚的数量、且由于数据组合的长度要大于单个音频数据的长度，提升了数据传输通道的利用率，从而实现了提升数据传输效率。
应理解，图1所示的智能座舱系统中，DSP芯片还可以与音频播放设备连接，用于播放SOC芯片发送的音频数据，在SOC芯片的管脚数量有限时，SOC芯片作为发送设备也可以采用图4所示的数据传输方法将待传输的音频传输叠加为至少一个数据传输组合，并通过数据传输通道传输给DSP芯片，此时DSP芯片作为接收设备可以采用图13所示的数据传输方法，接收SOC芯片发送的至少一个数据组合，对接收的数据组合进行拆分，得到多个音频数据，并通过数据接口输出给对应的音频播放设备。
