具体地，下面结合附图，对本申请实施例作进一步阐述。
图1是本申请实施例提供的数据传输方法的其中一种应用环境的示意图。具体地，如图1所示，该应用环境中包括：2个数据传输设备10。两个数据传输设备10之间无线通信连接，能够实现无线数据传输。任意两个数据传输设备10建立无线通信连接后，当其中一个数据传输设备10作为发送端时，另一个数据传输设备10为接收端。
其中，数据传输设备10是指能够进行无线数据传输的设备，可以是任意类型的智能终端，比如：无人机、遥控器、无人船、智能手机、个人电脑等等。并且，在本实施例中，这两个数据传输设备10可以是同一类型的智能终端，比如，其中一个数据传输设备10为一无人机，另一个数据传输设备10也为一无 人机，这两个无人机之间能够实现无线数据传输；或者，这两个数据传输设备10也可以是不同类型的智能终端，比如：其中一个数据传输设备10为一无人机，另一个数据传输设备为一遥控器(或者飞控设备)，该无人机可以与该遥控器(或者飞控设备)之间能够实现无线数据传输。
具体地，在本实施例中，每一数据传输设备10包括外部接口11、与外部接口11连接的数字基带12、与数字基带12连接的第一模拟基带131和第二模拟基带132，以及，分别与第一模拟基带131和第二模拟基带132连接的第一射频前端141和第二射频前端142。
外部接口11可以是任意类型的数据传输接口，比如：USB。当数据传输设备10作为数据发送端时，其外部接口11用于获取/接收该数据传输设备10(发送端)将要发送给另一个数据传输设备10(接收端)的数据；而当数据传输设备10作为数据接收端时，其外部接口11用于将另一个数据传输设备10(发送端)发送的数据传输给其应用层使用。
数字基带12可以是任意合适的具有一定计算能力的中央处理器或者微处理器，用于对获取到的信号以及数据进行处理。比如，当数据传输设备10作为数据发送端时，其数字基带12可以对接收到的数据进行预处理，然后将经过预处理后的数据发送至第一模拟基带131和/或第二模拟基带132；而当数据传输设备10作为数据接收端时，其数字基带12可以对从第一模拟基带131和/或第二模拟基带132接收到的数据进行处理，然后将处理后的数据发送至其外部接口11。
第一模拟基带131和第二模拟基带132可以是一电路芯片，用于对接收到的数据的信号类型进行转换以及对数据进行传输，比如，当数据传输设备10作为数据发送端时，将从数字基带12中获取到的数字信号转换成模拟信号以供对应的射频前端发射；或者，当数据传输设备10作为数据接收端时，将从对应的射频前端接收到的模拟信号转换为数字信号供数字基带12处理。其内部的功能单元可以包括但不限于：数/模转换器、模/数转换器、调制解调器、锁相环、放大器等等。

基于上述结构，在本申请实施例中，在两个数据传输设备10之间实现数据传输的过程可以为：作为发送端的数据传输设备10通过外部接口11将数据输入数字基带12，数字基带12对接收到的数据进行相应的处理后将其发送至由第一模拟基带131和第一射频前端141构成的第一传输信道和/或由第二模拟基带132和第二射频前端142构成的第二传输信道，然后通过第一传输信道和第二传输信道配合传输所述数据。相应地，作为接收端的数据传输设备10通过其第一传输信道和/或第二传输信道接收到数据后，将数据传输给其数字基带12，其数字基带12对接收到的数据进行处理后，比如，校验、合并等，将处理后的数据通过外部接口11传输给应用层，从而完成数据的传输。
此外，需要说明的是，本申请实施例提供的数据传输方法包括数据发送方法和数据接收方法，这两种方法可以相互配合使用，也可以单独使用。并且，本申请实施例提供的数据传输方法还可以进一步的拓展到其他合适的应用环境中，而不限于图1中所示的应用环境。在实际应用过程中，该应用环境还可以包括更多的数据传输设备。
具体地，请参阅图2，本申请一种数据传输方法实施方式包括：
步骤101：接收数据；
在本实施例中，所述“数据”是所有能够输入计算机(或者，任意类型的处理器)进行处理，并且具有一定意义的数字、字母、符号和模拟量等的统称，是待传输的信息的表现形式和载体。其中，该待传输的信息可以包括但不限于：控制指令、文本、图像、语音、视频等。因此，在本实施例中，所述“数据”的类型可以包括但不限于：控制指令数据、文本数据、图像数据、语音数据、视频数据等。
在本实施例中，发送装置的数字基带可以通过外部接口接收待传输的数据。数据进入到发送装置中的数字基带设备，数字基带将数据转换为数字信号进行传输给模拟基带(即，数字基带将数据转换为能够被第一模拟基带和/或第二模 拟基带识别的数字信号形式)。
步骤102：通过第一传输信道和第二传输信道配合传输所述数据,其中，所述第一传输信道是由第一模拟基带和与所述第一模拟基带连接的第一射频前端构建的，所述第二传输信道是由第二模拟基带和与所述第二模拟基带连接的第二射频前端构建的，其中，所述第一模拟基带和第一射频前端工作在第一频段，所述第二模拟基带和第二射频前端工作在第二频段，所述第一频段与第二频段不相同；
第一模拟基带、第一射频前端和第二模拟基带、第二射频前端是发送装置中不同频段的传输设备，模拟基带将数字信号转换为模拟信号，同时用来传输数据的第一传输信道和第二传输信道频段是不相同的，例如：第一传输信道为2.4G，第二传输信道为900M。
具体的，在一些实施例中，请参阅图3，步骤102可以包括：
步骤1021：复制所述数据生成数据副本；
在本实施例中，可以在数字基带中将所述数据内容复制生成副本，但为了所述数据内容和副本适应不同的传输信道，可以对两者进行不同的编码，值得说明的是，编码方式不会造成数据内容的改变。其中，对数据和数据副本进行编码的方式可以包括但不限于：卷积编码、交织编码、校验码MD5、奇偶校验码等。此外，还可以在数据/数据副本的编码中增加标志位，用于标识该数据/数据副本将要通过哪一个传输信道传输。
步骤1022：通过所述第一传输信道传输所述数据，以及通过所述第二传输信道传输所述数据副本；
在本实施例中，数字基带将编码后的数据和数据副本分别发送至第一传输信道和第二传输信道，然后通过第一传输信道传输数据，通过第二传输信道传输数据副本。具体为，数字基带将编码后的数据发送至第一模拟基带，第一模拟基带将该数据的信号类型由数字信号转换为模拟信号，并且，将该模拟信号的频段调整至第一发射前端的发射频段(即，第一频段)后由第一发射前端发射给接收端的第一发射前端；同时，数字基带将编码后的数据副本发送至第二模拟基带，第二模拟基带将该数据副本的信号类型由数字信号转换为模拟信号，并且，将该模拟信号的频段调整至第二发射前端的发射频段(即，第二频段)后由第二发射前端发射给接收端的第二发射前端。
第一传输信道和第二传输信道是独立的，因此，所述传输数据和所述数据副本相互不受任何影响，使数据在空间的并存度提高，没有应用场景的限制。
进一步地，在一些实施例中，请参阅图4，步骤102也可以包括：
步骤1023：通过所述第一传输信道传输所述数据；
所述第一传输信道用来传输数据，做单频段传输。
步骤1024：通过所述第二传输信道检测传输空间内是否存在干扰所述第一传输信道的干扰信号；
由于所述数据只在第一传输信道上传输，为了防止此数据受到破坏，因此所述第二传输信道即发送装置的第二模拟基带和第二射频前端检测传输空间内是否存在干扰所述第一传输信道的干扰信号，这样保证了数据的完整性和实时性。
具体地，可以首先将第二传输信道的工作频段调整至与第一传输信道相同的工作频段，然后通过第二传输信道检测该频段内各信道的信号强度，若第一传输信道的信号强度低于某一预设阈值，则可以认为传输空间内存在干扰第一传输信道的干扰信号。
步骤1025：若存在所述干扰信号，并且当所述数据传输信道接收数据的丢包率大于预定值时，则将所述数据由所述第一传输信道切换至所述第二传输信道传输，并向接收装置发送确定数据传输信道的确定信号；
丢包率是预设好的，例如预设丢包率是3％，如果丢包率达到3％或者大于3％，则切换传输数据的传输信道。切换信道的命令和向接收装置发送确定信号是由发送装置的第二模拟基带和第二射频前端执行，这样有利于接收装置在接收数据时不会因为信道的切换而耽误接收，保证了数据传输的实时性。
值得说明的是，如果数据因为受到干扰信号而破坏，则丢弃此数据，同时所述第二传输信道请求发送装置重新发送数据，通过第二传输信道传输数据，并且通知接收装置发送切换信道的信息。
步骤1026：若没有干扰信号，则继续由所述第一传输信道传输所述数据；
在数据正常传输的过程中，所述第二传输信道会一直检测，直到数据由接收装置接收。
或者，在另一些实施例中，为了规避恶意干扰的情况(比如，若竞争对手已知本数据传输设备的工作频段，并且故意在本数据传输设备传输数据时占据 多个该频段下的信道，使该频段内的信道过载，从而容易大大降低本数据传输设备传输数据的速度)，第一传输信道的工作频段(第一频段)和第二传输信道的工作频段(第二频段)不相同，当其中一个频段的传输信道受到的干扰较严重时，可以跳到另一个频段的传输信道传输数据，以提升数据传输的抗干扰能力。
具体地，请参阅图5，步骤102也可以包括：
步骤1029：实时检测所述第一传输信道和所述第二传输信道的信号强度。
在本实施例中，在同一时刻仅以其中一个传输信道做单频段载波传输数据。
一般地，传输信道可以通过接收到的反馈信号来判断其所在的工作频段内每一传输信道的信号强度，信号强度越强，说明传输信道越干净、干扰越少。因此，在本实施例中，在数据传输的过程中，用于传输数据的传输信道同样不断接收反馈信号以实时检测其信号强度，而另一个传输信道则做空口检测，即，仅接收反馈信号以实时检测其信号强度。
比如，假设当前通过第一传输信道传输数据，此时，第一传输信道除了传输数据外还不断接收反馈信号，并根据接收到的反馈信号实时检测第一传输信道的信号强度，而第二传输信道做空口检测，仅接收反馈信号，并根据接收到的反馈信号实时检测第二传输信道的信号强度，从而，通过比较第一传输信道和第一传输信道的信号强度的大小，可以确定哪一个传输信道更加干净，干扰更少。
步骤1020：当所述第一传输信道的信号强度高于所述第二传输信道的信号强度时，通过所述第一传输信道传输所述数据，当所述第一传输信道的信号强度低于所述第二传输信道的信号强度时，通过所述第二传输信道传输所述数据。
在本实施例中，当实时检测到第一传输信道的信号强度高于第二传输信道时，通过第一传输信道传输所述数据，当第一传输信道的信号强度低于第二传输信道时，通过第二传输信道传输所述数据。即，在传输数据的过程中，数据可以在第一传输信道和第二传输信道之间跳转，并且始终通过信号强度更强的传输信道传输数据。
比如，假设当前通过第一传输信道传输数据，若此时第一传输信道的信号强度高于第二传输信道的信号强度，则继续通过第一传输信道传输数据；若此时第一传输信道的信号强度低于第二传输信道的信号强度，则将数据切换至第 二传输信道进行传输，以此类推。
进一步地，在又一些实施例中，在传输数据的过程中还检测第一传输信道和第二传输信道的丢包率(即，1-接收端接收到的数据量/发送端发送的数据量)，当其中一个传输信道的丢包率大于或者等于预设门限值时，切换至另一个传输信道传输所述数据，从而保证数据的完整性。
再者，在一些实施例中，数字基带在接收到待传输的数据后，对该数据进行分割处理，并生成第一分割数据和第二分割数据。其中，所述第二分割数据为所述数据的核心内容，所述第一分割数据为所述数据中除核心内容以外的其它数据，并且所述第一分割数据的容量大于所述第二分割数据的容量。
具体地，所述核心内容是指接收到的数据中的关键数据，该关键数据的类型可以预先设定。比如，对于无人机来说，属于用于控制飞行、飞行姿态反馈、定位等影响无人机的基本飞行的数据为核心内容，航拍获得的图像等数据是非必要的，则为非核心内容。由此，当数字基带接收到待传输的数据后，可以首先对照预设的关键数据类型对数据进行分割处理，将属于关键数据类型的数据分割为第二分割数据，而其他数据分割为第一分割数据。
则，在该实施例中，请参阅图6，步骤102可以包括：
步骤1027：根据预设的加密算法，对所述第二分割数据进行加密处理；
加密算法可以预设成多种形式，根据核心内容的重要程度不同设置的密码难易程度可以不同，例如：不是特别重要的数据可以设置的密码是数字加英文字母，重要的数据可以设置的密码是数字加英文字母加特殊符号；当然，密码的长度也可设置一个固定值。
步骤1028：通过所述第一传输信道传输所述第一分割数据，以及通过所述第二传输信道传输所述加密后的第二分割数据。
所述第一传输信道的频段大于所述第二传输信道，第一传输信道用来传输容量大的第一分割数据，第二传输信道用来传输容量小的第二分割数据，由于两个传输信道是相互独立的，所以第一分割数据和第二分割数据互不影响。并且，通过频段较窄的第二传输信道来传输第二分割数据，抗干扰能力更强，防止丢失传输数据中的核心内容。
在本申请实施例中，通过发送装置中的第一、第二模拟基带和第一、第二射频前端进行构建第一、第二传输信道，并由第一、第二传输信道之间的配合 进行传输数据，通过在物理层中的模拟基带和射频前端对数据进行发送，利用两个传输信道的相互配合进行传输数据保证了数据传输的正确性，以最低的冗余设计实现了对实时数据的传输同时由于采用两个传输信道传输数据使数据在空间并存度提高，没有应用场景的限制。
请参阅图7，图7是本申请一种数据传输方法第二实施方式的流程图，数据传输方法包括：
步骤201：通过第一传输信道和第二传输信道接收数据，其中，所述第一传输信道是由第一模拟基带和与所述第一模拟基带连接的第一射频前端构建的，所述第二传输信道是由第二模拟基带和与所述第二模拟基带连接的第二射频前端构建的，其中，所述第一模拟基带和第一射频前端工作在第一频段，所述第二模拟基带和第二射频前端工作在第二频段，所述第一频段与第二频段不相同；
第一模拟基带、第一射频前端和第二模拟基带、第二射频前端是接收装置中不同频段的传输设备，第一模拟基带和第一射频前端处于一个频段，第二模拟基带和第二射频前端处于一个频段，同时用来传输数据的第一传输信道和第二传输信道频段也是不相同的，例如：第一传输信道为2.4G，第二传输信道为900M。
步骤202：根据接收到的数据，还原出完整数据；
由于发送装置发送的数据采用四种方式传输数据，因此接收装置接收的数据也是不同形式的，必须自行组出完整的数据，请参阅图8，步骤202包括：
步骤2021：解析所述数据，判断所述数据是否正确；
解析数据的方式也是按预设解析算法进行的，预设解析算法与预设封装算法相对应的，校验第一传输数据包是否正确的方式可以有多种，例如：在第一传输数据包中设置校验码，通过校验码校验第一传输数据包是否正确，或者，通过判断第一传输数据包是否包含首尾封装标识判断第一传输数据包是否正确。
步骤2022：如果所述数据是正确的，确定首次接收到的所述数据；
发送装置向接收装置发送数据时，分别通过第一传输信道和第二传输信道传输内容相同的数据，简而言之，一数据内容分别通过第一传输信道和第二传输信道向接收装置发送两次，但是接收装置从第一传输信道和第二传输信道接收数据可以有先后顺序之分。
值得说明的是，如果首次接收的数据不正确，则将首次接收的数据丢失， 等待另一个传输信道的数据，再进行解析。如果首次接收的数据正确，则可以直接将另一个传输信道的数据丢弃，以该数据作为首次接收到的正确的数据。
步骤2023：对首次接收到的所述数据进行处理；
判断数据存储空间是否存储有与所述首次接收的数据内容相同的数据，若存储空间存储有与所述首次接收的数据内容相同的数据则将数据内容存储至存储空间，否则丢弃该数据。
进一步地，请参阅图9，步骤201还包括：
步骤2011：通过第一传输信道或者第二传输信道接收确定信号，其中，所述确定信号用于从所述第一传输信道和第二传输信道中确定一个信道作为数据传输信道；
在本实施例中，在同一时刻仅以其中一个传输信道做单频段载波传输数据，数据可以合适的时机在两个传输信道之间跳转，而在数据跳转时，接收端可以从传输该数据的传输信道接收到确定信号，表明数据正在以该传输信道进行传输。
比如，在一些实施例中，由于发送端的第二传输信道进行空间检测，如果检测到干扰第一传输信道的信号，则数据传输的信道会由第一传输信道切换至第二传输信道，此时发送端会给接收端发送一个确定信号，这样将由第二传输信道接收数据，如果发送端的第二传输信道没有检测到干扰信号，则数据正常由第一传输信道传输，这样接收端是由第一传输信道接收数据。
又如，在另一些实施例中，发送端实时检测所述第一传输信道和所述第二传输信道的信号强度，当所述第一传输信道的信号强度高于所述第二传输信道的信号强度时，发送端以第一传输信道传输所述数据，此时，发送端会给接收端发送一个“以第一传输信道传输”的确定信号，接收端接收到该确定信号后通过其第一传输信道接收该数据；当第一传输信道的信号强度低于第二传输信道的信号强度时，发送端以第二传输信道传输所述数据，此时，发送端也会给接收端发送一个“以第二传输信道传输”的确定信号，接收端接收到该确定信号后通过其第二传输信道接收该数据。
步骤2012：在所述确定的数据传输信道上接收数据；
步骤2013：使用第一传输信道和第二传输信道之中不作为传输数据的传输信道检测另一条传输数据的数据传输信道的干扰信号；
其中一条传输信道用来传输数据，另一条不传输数据的传输信道进行检测整个空间是否存在干扰传输数据的传输信道的信号。
步骤2014：若存在所述干扰信号，并且当所述数据传输信道接收数据的丢包率大于预定值时，重新确定数据传输信道，并且向发送装置发送确定信号，以及返回在所述重新确定的数据传输信道上接收数据；
丢包率是预设好的，例如预设丢包率是3％，如果丢包率达到3％或者大于3％，则说明数据由于干扰信号已不完整，接收装置将向发送装置请求重新发送数据并切换信道，通过在物理层实现传输信道的切换，这样有利于数据传输的质量，并且提高数据传输的速度。
进一步地，请参阅图10，本申请一种数据传输方法还包括：
步骤203：根据预设的解密算法，对从所述第二传输信道接收到的数据进行解密；
预设的解密算法和预设的加密算法是相对应的。
进一步地，步骤202还包括：
步骤2024：将解密得到的数据和从所述第一传输信道接收到的数据组合成完整数据；
将解密得到的数据和从第一传输信道接收到的数据进行组合是在物理层实现的，保证传输给应用层的数据唯一且正确，实现了高效及时的数据传输。
在本申请实施例中，通过接收装置中的第一、第二模拟基带和第一、第二射频前端构建第一、第二传输信道，并由第一、第二传输信道接收数据并还原完整数据，通过在物理层中的模拟基带和射频前端对数据进行接收，并且通过在物理层实现传输信道的切换同时也在物理层进行数据的合并，这样保证了数据传输的延时小，提高了数据传输的效率。
