具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元， 而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
下面以具体地实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
无人驾驶车辆也被称为无人车，无人驾驶车辆是电子计算机等最新科技成果与现代汽车工业相结合的产物，通常具有自动驾驶，自动变速，自动识别道路的功能。无人车上有大量的数据采集装置，如视频图像采集装置、雷达测距装置、定位装置、体感装置等。无人车在行驶过程中，这些数据采集装置会实时采集大量的数据，并进行不断的存储，然后发送给云端服务器；或者，在无人车行驶结束之后，将行驶过程中的数据进行存储，然后一起发送给云端服务器。
但是，这种数据处理方式，会使得采集的数据占用无人车的大量存储空间，影响数据传输效率，带来网络拥堵等问题。同时，一些实时性要求高的数据只在无人车行驶过程中产生，而其他很多数据为实时性要求很低，可以在无人车充电等空闲时间，进行数据传输，合理利用资源。
针对上述技术问题，本申请提供一种方法，可以设置条件信息，可以实现对数据的差别化传输，减少无人车的数据存储量以及向云端服务器发送的数据量，节约网络资源，提高数据的传输效率。
图1为本申请一应用场景的原理示意图，如图1所示，云端服务器10与无人车20之间涉及到频繁的数据交互。而不同的数据，对于数据传输方式、实时性要求不同，可以对数据的差别化传输，从而提高数据的传输效率。首先，无人车10根据初始数据的数据标识，确定初始数据的优先级。然后，无人车对初始数据进行预处理，得到目标数据，并且根据初始数据的优先级，确定目标数据的传输方式。最后，无人车10按照传输方式，将目标数据发送给云端服务器10。
需要说明的是，云端服务器10可以同时与多个无人车20进行数据传输。可选地，云端服务器10与无人车20之间的通信方式还可以是除去OTA以外的无线传输方式，其实现原理与上述方法相类似，此处不再赘述。
应用上述方法可以实现对数据的差别化传输，减少无人车的数据存储量以及向云端服务器发送的数据量，节约网络资源，提高数据的传输效率。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描 述。
图2为本申请实施例一提供的无人车数据传输方法的流程图，如图2所示，本实施例中的方法可以包括：
S101、根据初始数据的数据标识，确定初始数据的优先级。
本实施例中，无人车的车机系统对初始数据的数据标识进行判断，若初始数据的数据标识为紧急事件数据标识，则初始数据的优先级为第一优先级；若初始数据的数据标识为地图众包数据标识，则初始数据的优先级为第二优先级；其中，第一优先级高于第二优先级。
具体地，无人车上有大量的数据采集装置，如视频图像采集装置、雷达测距装置、定位装置、体感装置等。无人车在行驶过程中，这些数据采集装置会实时采集大量的数据，同时无人车上也有很多离线数据包，如高精度地图导航包，应用软件基础数据包等。无人车车机系统中的这些数据产生的时间不同，对数据传输的要求也不同。例如，车载传感器上产生的数据，只在无人车行驶过程中产生，且对问题分析、自动驾驶等过程有着直接的影响，实时性高。而地图导航包、应用软件基础数据等，应用程序、离线地图的数据不影响无人车的安全，对数据实时性要求比较低，可以在无人车充电等空闲时间进行数据传输。因此，无人车将数据标识分为紧急事件数据标识和地图众包数据标识；其中，紧急事件数据标识对应的为实时性要求较高、且用于进行问题分析和算法改进的数据；地图众包数据标识对应的为实时性要求较低、数据量较大、处理逻辑复杂的数据。
需要说明的是，本实施例不限定数据标识的内容，本领域的技术人员可以根据实际情况增加或者减少数据标识的内容。
S102、对初始数据进行预处理，得到目标数据。
本实施例中，无人车根据初始数据的数据标识，确定初始数据的预处理方式；若初始数据的数据标识为紧急事件数据标识，则将初始数据进行关键数据提取和压缩处理，得到对应的目标数据；若初始数据的数据标识为地图众包数据标识，则将初始数据进行制图预处理，得到对应的目标数据。
具体地，对于初始数据的数据标识为紧急事件数据标识的数据，采用实时传输的方式。因此，需要考虑无人车的数据传输速度、数据传输带宽等因素，可以对初始数据进行关键数据提取和压缩处理，得到对应的目标数据。而对于初始数据的数据标识为地图众包数据标识的数据，采用实时性要求不高的传输方式，可以在无人车空闲时进行数据传输。因此，则对这部分数据进行制图预处理、预压缩处理等，得到对应的 目标数据
S103、根据初始数据的优先级，确定目标数据的传输方式。
本实施例中，若初始数据的优先级为第一优先级，则确定目标数据的传输方式为实时性传输；实时性传输是指，在无人车的行驶过程中，将生成的目标数据实时发送给云端服务器；若初始数据的优先级为第二优先级，则确定目标数据的传输方式为非实时性传输；非实时性传输是指，在无人车处于充电状态时，将预设时间段内生成的目标数据发送给云端服务器。
具体地，对于初始数据的优先级为第一优先级，则通过4G网络、空中下载技术(Over the Air，简称OTA)等方式进行实时传输至云端服务器。空中下载技术(Over the Air，简称OTA)，是通过移动通信的空中接口对卡数据及应用进行远程管理的技术。
空中接口可以采用无线应用通讯协议(Wireless Application Protocol，WAP)、通用分组无线服务技术(General Packet Radio Service，GPRS)、短消息技术。OTA技术的应用，使得移动通信不仅可以提供语音和数据服务，而且还能提供新业务下载。对于初始数据的优先级为第一优先级，则可以在无人车处于充电状态等空闲时段，通过4G或WiFi等方式将数据发送给云端服务器。
S104、按照传输方式，将目标数据发送给云端服务器。
本实施例中，根据传输方式，将处理后的目标数据发送给云端服务器，实现无人车数据的差别化传输，减少无人车的数据存储量以及向云端服务器发送的数据量，节约网络资源，提高数据的传输效率。
本实施例，通过根据初始数据的数据标识，确定初始数据的优先级；对初始数据进行预处理，得到目标数据；根据初始数据的优先级，确定目标数据的传输方式；按照传输方式，将目标数据发送给云端服务器。从而可以实现对数据的差别化传输，减少无人车的数据存储量以及向云端服务器发送的数据量，节约网络资源，提高数据的传输效率。
图3为本申请实施例二提供的无人车数据传输方法的流程图，如图3所示，本实施例中的方法可以包括：
S201、获取数据标识与优先级之间的对应关系，以及不同优先级数据的传输方式。
本实施例，可以对无人车的数据标识进行定义，建立数据标识与数据传输的优先级、数据传输方式之间的对应关系。
具体地，具体地，无人车上有大量的数据采集装置，如视频图像采集装置、雷达 测距装置、定位装置、体感装置等。无人车在行驶过程中，这些数据采集装置会实时采集大量的数据，同时无人车上也有很多离线数据包，如高精度地图导航包，应用软件基础数据包等。无人车车机系统中的这些数据产生的时间不同，对数据传输的要求也不同。
具体地，车载传感器上产生的数据，只在无人车行驶过程中产生，且对问题分析、自动驾驶等过程有着直接的影响，实时性高。而地图导航包、应用软件基础数据等，应用程序、离线地图的数据不影响无人车的安全，对数据实时性要求比较低，可以在无人车充电等空闲时间进行数据传输。因此，无人车将数据标识分为紧急事件数据标识和地图众包数据标识；其中，紧急事件数据标识对应的为实时性要求较高、且用于进行问题分析和算法改进的数据；地图众包数据标识对应的为实时性要求较低、数据量较大、处理逻辑复杂的数据。紧急事件数据标识对应的为第一优先级，采用实时性传输；而地图众包数据标识对应的为第二优先级，采用非实时性传输。
需要说明的是，本实施例不限定紧急事件数据的具体类型，用户可以根据实际情况将数据标记为紧急数据或者普通数据。除了地图众包数据之外，普通数据也可以在无人车充电等空闲时段进行统一传输。
S202、根据初始数据的数据标识，确定初始数据的优先级。
S203、对初始数据进行预处理，得到目标数据。
S204、根据初始数据的优先级，确定目标数据的传输方式。
S205、按照传输方式，将目标数据发送给云端服务器。

另外，本实施还可以定义数据标识与优先级之间的对应关系，以及不同优先级数据的传输方式。从而可以实现数据的差别化传输的基础数据定义，提高数据的传输效率。
