具体实施方式
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描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
本申请实施例中提供的数据处理方法可以应用于飞行设备中。在某些实施例中，所述 飞行设备中包括飞行控制系统(flight control system，FC)处理器和应用处理器(application processer，AP)。飞行控制系统处理器还可简称为飞控处理器，飞控处理器例如可以是微控制单元(micro controller unit，MCU)、单片微型计算机(single chip microcomputer，SCM)或者单片机。应用处理器例如可以是中央处理器(central processing unit，CPU)。其中，飞控处理器主要用于控制无人机的飞行，飞控处理器上设置的闪存容量较小(例如，常见的飞控处理器上Flash芯片的容量一般小于或等于1Mb)。而应用处理器的存储空间较大，例如一般可支持GB级别的存储空间。
随着飞行设备的应用越来越广泛，限飞区也变得越来越多，且限飞区的形状也越来越复杂，复杂的多边形限飞区使用的数据库较大(例如大于10MB)。如果由飞控处理器执行限飞控制及限飞数据库存储，则飞控处理器所使用的MCU一般只有不到1MB的片上Flash，无法用于存储复杂且数量庞大的限飞区的数据库。如果为飞控处理器配属一个资源充足的高性能处理器，来完成大数据库的存储和所有限飞区域的相关计算，会带来很大的硬件成本增加。如果由应用处理器执行限飞控制及限飞数据库存储，则应用处理器每次进行限飞区域的计算时，均会一次性读取数据库中的全部限飞区数据，对限飞区数据的一次性读入会造成很大的内存消耗，且读入内存中的大部分数据在一次飞行过程中很大概率不会使用到。并且应用处理器还可能被root，存在数据被篡改的风险。因此，基于限飞控制的需求，在本申请的一种实施例中采用飞控处理器执行限飞区域的计算以及飞行设备的飞行控制，将庞大的限飞数据库存储在应用处理器。通过这种方式可以无需由飞控处理器存储限飞数据库，避免增加额外的硬件存储成本。
可选的，还可以将限飞数据库存储在远端的设备上，例如控制器、终端、服务器等。飞控处理器通过无线通信接口与远端的设备进行通信。在某些实施例中，所述飞行设备包括用于为飞行设备提供移动动力的一个或多个电机，所述飞行设备可以是任务依靠所述电机自主移动的无人机、飞行器等。在其他实施例中，本申请实施例中所提及的数据处理方法还可以应用于其他可移动设备上，如能够自主移动的机器人、无人车、无人船等可移动设备。
下面结合图1a和图1b对本申请实施例提供的飞控系统进行示意性说明。
请参见图1a，图1a是本申请实施例提供的一种飞控系统的结构示意图。所述飞行控制系统包括：飞行设备11和控制设备12，飞控处理器111和应用处理器113均位于飞行设备11上，应用处理器113用于存储限飞数据库。即，飞行控制器与用于存储限飞数据库的存 储设备位于同一设备上。在某些实施例中，所述飞行设备11包括动力系统112，所述动力系统112用于为飞行设备11提供移动的动力。
请参见图1b，所述飞行控制系统包括：飞行设备11和控制设备12，飞控处理器111位于飞行设备11上，控制设备12用于存储限飞数据库。即，飞行控制器与用于存储限飞数据库的存储设备位于不同的设备上。在某些实施例中，所述控制设备包括终端、控制器、服务器等中的任意一种。如图1b所示，控制设备12可通过无线通信连接方式与飞行设备11建立通信连接。在某些实施例中，所述飞行设备11包括动力系统112，所述动力系统112用于为飞行设备11提供移动的动力。
需要说明的是，在图1a中，飞控处理器111和应用处理器113的安装位置仅用于表征飞控处理器111和应用处理器113是设置在飞行设备11上的，并非用于限定飞控处理器111和应用处理器113在飞行设备11上的安装位置，例如，飞控处理器111和应用处理器113可以安装在飞行设备11内部。同样的，在图1b，飞控处理器111的安装位置仅用于表征飞控处理器111是设置在飞行设备11上的，并非用于限定飞控处理器111在飞行设备11上的安装位置，例如，飞控处理器111可以安装在飞行设备11内部。
以存储设备为应用处理器为例，应用处理器按块存储限飞数据库，存储格式可参见图2所示。其中，每个数据块有对应的签名，例如，数据块1与签名1对应，数据块2与签名2对应。签名可用于校验数据块的完整性和正确性。数据库头部信息中包含数据块的地址信息、数据块的大小、数据块的签名的地址信息、总数据块的数量等信息。应用处理器具备读取接口，飞控处理器需要获取当前位置周围的目标限飞区数据时，通过该读取接口向应用处理器发送读取请求，该读取请求携带目标限飞区数据所属数据块的地址，应用处理器响应该读取请求，向飞控处理器返回相应地址的限飞区数据。飞控处理器根据该限飞区数据进行限飞区域的计算以及飞行设备的飞行控制。通过设计这种分块读取的方案可以避免一次性读取全部的限飞区数据，提高了数据处理效率，降低了内存消耗。
基于分块读取的策略，需要约束限飞数据库中的数据块大小，限飞数据库中的每一数据块不能太小，否则签名造成的开销会很大。例如将限飞数据库中的数据块大小设置为比较常见的1KB，为了完成数据校验，每次飞控处理器需要至少读取1KB的数据。由于飞控处理器的性能低，其带宽能力也较低，1KB的数据块大小超过了FC-AP通信链路能力。为满足低链路带宽能力的FC在较低的链路下完成限飞数据库的分块读取，可以解除限飞对FC链路带宽的要求，本申请实施例中提供了一种限飞数据库分块读取代理机制。例如，参 见图3所示的架构示意图，数据库读取由AP与FC共同完成。其中数据库存储在AP侧文件系统中，AP提供随机读取接口，响应FC读取请求，返回相应地址的对应数据，如图3中所示AP包括读取(reader)接口和数据库(database)。FC包括安全飞行(flysafe)模块和代理(agent)模块。其中flysafe模块执行限飞的功能逻辑，给出需要的限飞区数据在数据库中的长度和地址。agent模块是限飞数据库读取代理模块，完成目标地址和长度到目标数据块的转换，再根据FC配置的物理链路带宽，拆分成符合链路要求的小包后，分别向AP发起多次读取请求，获取到完整数据后再将数据拼接，然后请求签名，对数据做签名校验，符合要求则交给flysafe模块做功能逻辑使用。
下面结合附图4-图6对本申请实施例提供的数据处理方法进行示意性说明。
具体请参见图4，图4是本申请实施例提供的一种数据处理方法的流程示意图，所述数据处理方法可以由飞控处理器执行。具体地，本申请实施例的所述方法包括如下步骤。
S401：飞控处理器向存储设备发送获取请求，获取请求用于请求获取目标限飞区数据所属目标数据块中的部分数据，目标限飞区数据用于飞控处理器进行限飞控制，存储设备中存储一个或多个数据块，数据块的长度大于等于飞控处理器和存储设备之间单次传输的最大数据长度，部分数据的数据长度小于等于飞控处理器和存储设备之间单次传输的最大数据长度。
S402：飞控处理器接收存储设备发送的目标数据块中的部分数据。
本申请实施例中，飞控处理器需要设置每次请求获取的数据的最大长度，单次请求获取的最大数据长度需要小于等于飞控处理器和存储设备之间单次传输的最大数据长度。飞控处理器和存储设备之间单次传输的最大数据长度与飞控处理器的物理带宽相关，例如，飞控处理器的物理带宽为300B，则表示飞控处理器单次向其他器件发送的或者单次从其他器件接收的数据量最大为300B。飞控处理器发送的获取请求中携带请求获取的数据的地址信息，该数据的长度需要设置为小于等于飞控处理器和存储设备之间单次传输的最大数据长度的值。因此，飞控处理器单次向存储设备请求的数据量不会超过飞控处理器和存储设备之间单次传输的最大数据长度，如此可以保证不管飞控处理器的通信链路能力高或低，单次传输的数据量均不会超过FC的通信链路能力。其中，地址信息可以包括起始地址和长度，或者包括起始地址和结束地址，或者包括结束地址和长度。本申请实施例中，数据长度还可以称为数据量、数据大小等。
可选的，飞控处理器可以根据飞行设备当前的地理位置信息计算出需要获取的目标限 飞区数据的地址信息。之后，根据目标限飞区数据的地址信息确定目标限飞区数据对应的目标数据块。例如，飞控处理器确定与所述当前位置信息对应的目标限飞区数据的地址信息时，可以根据所述飞行设备的当前位置信息，确定所述飞行设备的当前位置对应的目标编码值，并根据所述目标编码值，从地址映射表中确定与所述目标编码值对应的所述目标限飞区数据的地址信息，所述地址映射表中包括一个或多个编码值与一个或多个限飞区数据的地址信息的对应关系。
在某些实施例中，所述编码值可以是由哈希算法计算得到的，所述编码值为哈希值。在其他实施例中，所述编码值还可以是由其他编码算法计算得到。在其他实施例中，所述编码值还可以是由用户自定义的编码规则计算得到，本发明实施例不做具体限定。可选的，所述飞行设备的当前位置信息包括但不限于GPS位置信息。可选的，所述地址映射表可以存储在飞控处理器，还可以是飞控处理器从存储设备获取的，例如，飞控处理器预先从存储设备获取数据库头部信息，该数据库头部信息中包含所述地址映射表。可选的，该数据库头部信息中还包括存储设备中存储的每个数据块的地址信息。飞控处理器在获取到数据库头部信息后，根据目标限飞区数据的地址信息以及存储设备中存储的每个数据块的地址信息确定目标限飞区对应的目标数据块。例如，飞控处理器根据飞行设备当前GPS位置计算得到目标限飞区数据的地址信息为500-1500，根据数据库头部信息获知存储设备中存储的数据块大小为1K，且数据块1的地址信息为1-1000，数据块2的地址信息为1001-2000，以此类推。则飞控处理器可以根据目标限飞区数据的地址信息500-1500以及存储设备中存储的数据块的地址信息确定目标限飞区数据所属的目标数据块为数据块1和数据块2。
可选的，所述飞控处理器向存储设备发送获取请求，包括：飞控处理器依次向存储设备发送多次获取请求直至飞控处理器接收到目标数据块中的全部数据，每次获取请求用于请求获取目标数据块中的不同数据；飞控处理器接收存储设备发送的目标数据块中的部分数据，包括：飞控处理器依次从存储设备接收多次目标数据块中的部分数据。
本申请实施例中，飞控处理器向存储设备发送获取请求之前，需要将用于获取目标数据块的一次获取请求拆分成多个获取请求，每次获取请求用于获取目标数据块中的部分数据的，每次请求的数据量均需要小于等于飞控处理器和存储设备之间单次传输的最大数据长度。示例性的，飞控处理器可以根据飞控处理器的物理带宽将用于获取目标数据块的一次获取请求拆分成多个用于获取目标数据块中的部分数据的获取请求。例如，存储设备上存储的数据块大小为1KB，FC需要获取的目标限飞区数据的地址为1-1000，每个地址对应一个1Byte的数据，该地址为1-1000的数据在存储设备上对应数据块1。FC链路单次最 大允许传输300B数据，则飞控处理器需要分为300B，300B，300B，100B，一共四次去向存储设备请求获取这1KB的数据。当然，300B，300B，300B，100B仅仅作为一种示例，在实际应用中，每次获取的数据量还可以设置成其他的值或者获取请求的发送次数还可以是其他次数，只需要满足单次传输的数据量小于等于飞控处理器和存储设备之间单次传输的最大数据长度且多次获取的总的数据量至少包括目标数据块即可，本申请实施例对此不作限定。例如飞控处理器分为200B，200B，200B，200B，200B一共五次去向存储设备请求获取1KB的数据。
可选的，飞控处理器针对目标数据块分别发送多次获取请求时，每次请求的数据可以完全不同。例如，FC需要获取的目标限飞区数据的地址为1-1000，则飞控处理器发送第一次获取请求时请求获取地址为1-300的数据，发送第二次获取请求时请求获取地址为301-600的数据，发送第三次获取请求时请求获取地址为601-900的数据，发送第四次获取请求时请求获取地址为901-1000的数据。
可选的，飞控处理器针对目标数据块分别发送多次获取请求时，每次请求的数据可以部分相同。例如，FC需要获取的目标限飞区数据的地址为1-1000，则飞控处理器发送第一次获取请求时请求获取地址为1-300的数据，发送第二次获取请求时请求获取地址为250-550的数据，发送第三次获取请求时请求获取地址为500-800的数据，发送第四次获取请求时请求获取地址为750-1000的数据。多次传输部分重复的数据可以提高数据传输的可靠性。
可选的，飞控处理器向存储设备发送获取请求之前，还可以从存储设备获取数据库头部信息。该数据库头部信息中包括存储设备中存储的一个或多个数据块中每个数据块的地址信息、数据块的大小。飞控处理器根据该数据库头部信息确定目标数据块的地址信息。可选的，该数据库头部信息中还可以包括总数据块的数量等信息。
可选的，数据库头部信息还可以预先存储在飞控处理器，则飞控处理器无需向存储设备获取该数据库头部信息。
可选的，数据库头部信息中还可以包括数据块的签名的地址信息。在某些实施例中，数据库的头部信息中还存储了一个或多个数据块的签名的地址信息与一个或多个数据块的地址信息的对应关系，如数据块1与签名1对应，数据块2与签名2对应。
可选的，所述飞控处理器从存储设备接收到目标数据块中的全部数据之后，还包括：飞控处理器从存储设备获取目标数据块的签名；飞控处理器根据签名对目标数据块进行验证。例如，飞控处理器从数据库头部信息中查找目标数据块对应的签名的地址信息，向存 储设备发送获取签名的请求，该请求中携带目标数据块对应的签名的地址信息，飞控处理器接收存储设备发送的该目标数据块对应的签名，并根据该签名对目标数据块进行验证。
可选的，若飞控处理器对目标数据块验证成功，飞控处理器根据目标数据块中的数据合成目标限飞区数据。例如，飞控处理器分四次从存储设备获取到300B，300B，300B，100B，一共1KB的数据后，按照数据的地址将这1KB的数据进行拼接，合成1KB的数据。
可选的，若飞控处理器对目标数据块验证成功，飞控处理器将目标数据块中的数据存储在存储器中。其中，存储器包括但不限于缓冲器或缓存。将目标数据块存储在飞控处理器的存储器中，便于后续飞控处理器再次需要获取该目标数据块时可以直接从本地存储器中获取，而无需再次向存储设备请求获取，可以缩短数据获取的时间，提高数据获取的效率。
可选的，由于飞控处理器的存储空间较小，无法存储较多数量的限飞区数据块，则飞控处理器可以在存储空间占满后，下一次获取到新的限飞区数据块后，替换掉存储空间中已存的较早的数据块，完成对存储器中限飞区数据块的更新。
可选的，所述飞控处理器根据签名对目标数据块进行验证，包括：飞控处理器根据预设的密钥对目标数据块进行计算，得到验证签名；飞控处理器将签名与验证签名进行对比；如果签名与验证签名一致，则飞控处理器确定对目标数据块验证成功。
例如，假设预设的密钥为X，飞控处理器在根据签名对目标数据块进行验证时，可以根据预设的密钥X对目标数据块进行计算，得到验证签名，并将签名与验证签名进行对比，如果签名与验证签名一致，则可以确定对目标数据块验证成功。
可见，通过这种实施方式，可以对目标数据块的签名进行验证，有助于确保目标数据块对应的限飞区数据的安全性。
可选的，所述飞控处理器向存储设备发送获取请求之前，还包括：飞控处理器查找存储器中是否存在所述部分数据；若否，则所述飞控处理器向所述存储设备发送所述获取请求。若是，则无需向所述存储设备发送获取请求，所述飞控处理器从所述存储器中获取所述部分数据。例如，FC需要获取的目标限飞区数据的地址为1-1500，缓存中存储了上次获取的1-1000的限飞区数据块，则FC可以只针对地址为1001-1500的数据向存储设备发送获取请求即可，在获取到地址为1001-1500的数据后，与缓存中存储的1-1000的数据进行拼接，合成FC所需的地址为1-1500的数据。
可选的，限飞数据库可以不存放在一个存储设备中，限飞数据库可以拆分成若干个子数据库分别存储在不同的存储设备上，由飞控处理器负责向不同存储设备去请求限飞区数 据。
在一些应用场景中，所述飞控处理器和所述存储设备可以位于同一设备中。
可选的，所述同一设备为飞行设备，所述存储设备为应用处理器。飞控处理器可以是FC的处理器如MCU。应用处理器可以为AP。飞控处理器和应用处理器之间是通过总线连接的。
在一些应用场景中，所述飞控处理器和所述存储设备位于不同设备中。
可选的，所述飞控处理器位于飞行设备上，所述存储设备为所述飞行设备的控制设备。可选的，所述控制设备包括终端、控制器或服务器。则飞控处理器和存储设备是通过收发器来通信的，飞控处理器生成的数据通过飞行设备的收发器发送给存储设备，同样的，飞行设备的收发器接收到存储设备发送的数据后，再通过总线传送给飞控处理器。即可以理解为：飞行设备包括：飞控处理器、应用处理器以及收发器，进一步的，飞行设备还可以包括各种传感器、动力系统等，其中，飞控处理器是专门处理飞控相关的执行指令，如确定是否落入限飞区，是否需要改变航线等。
可选的，飞控处理器在获取目标限飞区数据后，还可以根据所述目标限飞区数据以及飞行设备的位置信息对所述飞行设备进行限飞控制。示例性的，飞控处理器根据所述目标限飞区数据以及飞行设备的位置信息对所述飞行设备进行限飞控制，包括：
若所述飞行设备落入所述目标限飞区，则控制所述飞行设备降落；或者，
若所述飞行设备未落入所述目标限飞区且所述飞行设备与所述目标限飞区的距离小于等于预设阈值，则控制所述飞行设备远离所述目标限飞区；或者，
若所述飞行设备未落入所述目标限飞区且所述飞行设备与所述目标限飞区的距离小于等于预设阈值，则控制所述飞行设备降落或悬停。预设阈值可以是系统预先设定的。
实施本申请实施例，由存储设备存储全部的限飞数据库，飞控处理器根据需求向存储设备获取部分限飞数据块进行飞行设备的飞行控制，无需读取全部的限飞区数据库，通过这种分块读取的方式，可以提高数据处理效率，降低内存消耗。并且，飞控处理器向存储设备单次请求获取的数据量有限制，不能超过飞控处理器和存储设备之间单次传输的最大数据长度，若飞控处理器请求的数据量较大，则通过向存储设备发送多次请求来获取，避免因存储设备单次向飞控处理器传输的数据量过大而飞控处理器的物理带宽不足造成数据无法成功接收的问题。实施本申请实施例，不必增加FC与存储设备间的带宽，可以很好的适配现有机型的硬件条件，同时对于将来不同机型不同硬件的不同链路带宽，只需要修改飞控处理器的链路配置(即单次传输的最大数据长度)即可，不需要修改存储设备中数 据块的大小配置，数据库能有很大自由度。同时因为飞控处理器会对目标数据块做缓存，读取之前会先查找自己的缓存中是否有，所以可以避免短时间内的重复读取，降低链路负担，同时可以提高数据的获取效率。
具体请参见图5，图5是本申请实施例提供的另一种数据处理方法的流程示意图，所述方法可以由存储设备执行。具体地，本申请实施例的所述方法包括如下步骤。
S501：存储设备接收飞控处理器发送的获取请求，获取请求用于请求获取目标限飞区数据所属目标数据块中的部分数据，目标限飞区数据用于飞控处理器进行限飞控制，存储设备中存储一个或多个数据块，数据块的长度大于等于飞控处理器和存储设备之间单次传输的最大数据长度，部分数据的长度小于等于飞控处理器和存储设备之间单次传输的最大数据长度。
S502：存储设备将目标数据块中的部分数据发送给飞控处理器。
本申请实施例中，存储设备接收的单次获取请求中请求获取的数据最大长度需要小于等于飞控处理器和存储设备之间单次传输的最大数据长度。飞控处理器和存储设备之间单次传输的最大数据长度与飞控处理器的物理带宽相关，例如，飞控处理器的物理带宽为300B，则单次获取请求中请求获取的数据最大为300B。存储设备接收的获取请求中携带飞控处理器请求获取的数据的地址信息，该数据的长度需要为小于等于飞控处理器和存储设备之间单次传输的最大数据长度的值。因此，飞控处理器单次向存储设备请求的数据量不会超过飞控处理器和存储设备之间单次传输的最大数据长度，如此可以保证不管飞控处理器的通信链路能力高或低，单次传输的数据量均不会超过FC的通信链路能力。其中，地址信息可以包括起始地址和长度，或者包括起始地址和结束地址，或者包括结束地址和长度。本申请实施例中，数据长度还可以称为数据量、数据大小等。
可选的，所述存储设备接收飞控处理器发送的获取请求，包括：存储设备依次接收飞控处理器发送的多次获取请求；存储设备将目标数据块中的部分数据发送给飞控处理器，包括：存储设备依次向飞控处理器发送多次目标数据块中的部分数据。本申请实施例中，存储设备连续接收到多次获取请求，该多次获取请求各自请求的数据可以是连续的，且每次请求的数据的长度均小于等于飞控处理器和存储设备之间单次传输的最大数据长度。例如，存储设备上存储的数据块大小为1KB，FC需要获取的目标限飞区数据的地址为1-1000，每个地址对应一个1Byte的数据，该地址为1-1000的数据在存储设备上对应数据块1。FC链路单次最大允许传输300B数据，则存储设备会连续接收到飞控处理器发送的4 次获取请求，该4次获取请求依次请求获取的数据大小为300B，300B，300B，100B。当然，300B，300B，300B，100B仅仅作为一种示例，在实际应用中，每次获取的数据量还可以设置成其他的值或者获取请求的发送次数还可以是其他次数，例如存储设备会连续接收到飞控处理器发送的5次获取请求，该5次获取请求依次请求获取的数据大小为200B，200B，200B，200B，200B。其中，“连续”是指两次接收到获取请求的时间间隔小于预设时间阈值。
可选的，存储设备连续接收到的多次获取请求中，每次请求的数据可以完全不同。例如，FC需要获取的目标限飞区数据的地址为1-1000，则存储设备第一次接收到飞控处理器发送的获取请求中携带的地址为1-300，第二次接收到飞控处理器发送的获取请求中携带的地址为301-600，第三次接收到飞控处理器发送的获取请求中携带的地址为601-900，第四次接收到飞控处理器发送的获取请求中携带的地址为901-1000。
可选的，存储设备连续接收到的多次获取请求中，每次请求的数据可以部分相同。例如，FC需要获取的目标限飞区数据的地址为1-1000，则存储设备第一次接收到飞控处理器发送的获取请求中携带的地址为1-300，第二次接收到飞控处理器发送的获取请求中携带的地址为250-550，第三次接收到飞控处理器发送的获取请求中携带的地址为500-800，第四次接收到飞控处理器发送的获取请求中携带的地址为750-1000。多次传输部分重复的数据可以提高数据传输的可靠性。
可选的，存储设备依次向飞控处理器发送多次目标数据块中的部分数据之后，还包括：存储设备向飞控处理器发送目标数据块的签名，签名用于验证目标数据块。
可选的，所述获取请求中包括部分数据的地址信息，存储设备接收飞控处理器发送的获取请求之前，还包括：存储设备向飞控设备发送数据库头部信息，数据库头部信息包括一个或多个数据块中每个数据块的地址信息。可选的，该数据库头部信息中还可以包括总数据块的数量等信息。可选的，数据库头部信息中还可以包括数据块的签名的地址信息。在某些实施例中，数据库的头部信息中还存储了一个或多个数据块的签名的地址信息与一个或多个数据块的地址信息的对应关系，如数据块1与签名1对应，数据块2与签名2对应。
可选的，限飞数据库可以不存放在一个存储设备中，限飞数据库可以拆分成若干个子数据库分别存储在不同的存储设备上，由飞控处理器负责向不同存储设备去请求限飞区数据。
在一些应用场景中，所述飞控处理器和所述存储设备可以位于同一设备中。
可选的，所述同一设备为飞行设备，所述存储设备为应用处理器。飞控处理器可以是 FC的处理器如MCU。应用处理器可以为AP。飞控处理器和应用处理器之间是通过总线连接的。
在一些应用场景中，所述飞控处理器和所述存储设备位于不同设备中。
可选的，所述飞控处理器位于飞行设备上，所述存储设备为所述飞行设备的控制设备。可选的，所述控制设备包括终端、控制器或服务器。则飞控处理器和存储设备是通过收发器来通信的，飞控处理器生成的数据通过飞行设备的收发器发送给存储设备，同样的，飞行设备的收发器接收到存储设备发送的数据后，再通过总线传送给飞控处理器。即可以理解为：飞行设备包括：飞控处理器、应用处理器以及收发器，进一步的，飞行设备还可以包括各种传感器、动力系统等，其中，飞控处理器是专门处理飞控相关的执行指令，如确定是否落入限飞区，是否需要改变航线等。
实施本申请实施例，由存储设备存储全部的限飞数据库，飞控处理器根据需求向存储设备获取部分限飞数据块进行飞行设备的飞行控制，无需读取全部的限飞区数据库，通过这种分块读取的方式，可以提高数据处理效率，降低内存消耗。并且，飞控处理器向存储设备单次请求获取的数据量有限制，不能超过飞控处理器和存储设备之间单次传输的最大数据长度，若飞控处理器请求的数据量较大，则通过向存储设备发送多次请求来获取，避免因存储设备单次向飞控处理器传输的数据量过大而飞控处理器的物理带宽不足造成数据无法成功接收的问题。实施本申请实施例，不必增加FC与存储设备间的带宽，可以很好的适配现有机型的硬件条件，同时对于将来不同机型不同硬件的不同链路带宽，只需要修改飞控处理器的链路配置(即单次传输的最大数据长度)即可，不需要修改存储设备中数据块的大小配置，数据库能有很大自由度。同时因为飞控处理器会对目标数据块做缓存，读取之前会先查找自己的缓存中是否有，所以可以避免短时间内的重复读取，降低链路负担，同时可以提高数据的获取效率。
在本申请的一种实现方式中，飞控处理器可以包括安全飞行(flysafe)模块和代理(agent)模块。该两个模块是相互独立的。该两个模块可以是软件模块或硬件模块，可独立开发。其中，代理模块用于向存储设备发送获取请求以及接收存储设备发送的目标数据块中的部分数据，代理模块还用于根据存储设备发送的目标数据块中的数据合成目标限飞区数据以及将目标限飞区数据发送给安全飞行模块。安全飞行模块用于根据目标限飞区数据以及飞行设备的位置信息对飞行设备进行限飞控制。也即是说，agent模块负责与存储设备进行交互，flysafe模块负责执行限飞的相关逻辑计算以及完成对飞行设备的飞行控制。以存储设 备为应用处理器为例，应用处理器包括读取(reader)接口和数据库。
参见图6所示，是本申请实施例提供的飞控处理器和应用处理器的交互过程示意图。该交互过程如下：
S601：代理模块通过读取接口向应用处理器获取数据库头部信息。
其中，该数据库头部信息中包括存储设备中存储的一个或多个数据块中每个数据块的地址信息、数据块的大小、总数据块的数量、数据块的签名的地址信息、地址映射表中的一种或多种信息。其中，所述地址映射表中包括一个或多个编码值与一个或多个限飞区数据的地址信息的对应关系。
S602：安全飞行模块向代理模块请求获取目标限飞区数据。
示例性的，安全飞行模块根据当前飞行设备的位置计算出需要读取的目标限飞区数据在数据库中的地址和长度，将目标限飞区数据的地址和长度发给代理模块。可选的，安全飞行模块根据飞行设备当前的地理位置信息，确定飞行设备的当前位置对应的目标编码值，从地址映射表中确定与所述目标编码值对应的所述目标限飞区数据的地址信息和/或长度。其中，地址映射表可以是代理模块从数据库头部信息中获取后发送给安全飞行模块，安全飞行模块存储在缓冲区或内存中的。
S603：代理模块确定目标限飞区数据所属的目标数据块。
目标限飞区数据所属目标数据块可以理解为：数据块中包含的数据为限飞区数据，且一个数据块中可以包括一个或多个限飞区的数据，目标限飞区数据所在的数据块即为目标数据块。
示例性的，代理模块根据目标限飞区数据的地址和长度计算出目标限飞区数据所属的目标数据块。
S604：代理模块查找缓冲器中是否存在目标数据块，若是，将目标限飞区数据发送给安全飞行模块；若否，执行步骤S605。
S605：代理模块通过读取接口分多次向应用处理器发送获取请求，请求获取目标数据块中的数据。
S606：应用处理器的读取接口在接收到获取请求后，根据获取请求中携带的数据的地址从数据库中读取对应地址的数据并发送给代理模块。
示例性的，由于应用处理器中存储的数据块的大小通常大于FC的带宽性能，为了适应FC的低通信链路性能，代理模块跟据实际的物理带宽将目标数据块拆成若干次请求依次向AP去获取数据(例如：目标数据块为1个，且大小为1KB，FC链路最大允许300B， 则代理模块需要分为300B，300B，300B，100B，一共四次去向AP请求获取这1KB的数据)。假设第一次获取请求中携带的地址为1-300，则读取接口在接收到该获取请求后，根据获取请求中携带的数据的地址1-300从数据库中读取地址1-300对应的数据并发送给代理模块。第二次获取请求中携带的地址为301-600，则读取接口在接收到该获取请求后，根据获取请求中携带的数据的地址301-600从数据库中读取地址301-600对应的数据并发送给代理模块。第三次获取请求中携带的地址为601-900，则读取接口在接收到该获取请求后，根据获取请求中携带的数据的地址601-900从数据库中读取地址601-900对应的数据并发送给代理模块。第四次获取请求中携带的地址为901-1000，则读取接口在接收到该获取请求后，根据获取请求中携带的数据的地址901-1000从数据库中读取地址901-1000对应的数据并发送给代理模块。代理模块在接收到目标数据块的全部数据后，将收到的数据重新拼接成一个完整的数据块。
S607：代理模块通过读取接口从应用处理器获取目标数据块的签名，根据签名对目标数据块进行校验，校验成功则将目标数据块存入缓冲器并向安全飞行模块返回目标限飞区数据。
示例性的，代理模块根据数据库头部信息查找目标数据块对应的签名的地址信息，并通过读取接口向AP请求该签名。代理模块对拼接后的数据块计算签名，并与从AP请求到的签名做比对，如果一致则读取成功向安全飞行模块返回目标限飞区数据，同时将目标数据块进行存储。
S608：安全飞行模块收到读取成功的目标限飞区数据，进行限飞功能的逻辑处理。
示例性的，安全飞行模块用于根据目标限飞区数据以及飞行设备的位置信息对飞行设备进行限飞控制。例如，若飞行设备落入目标限飞区，则控制飞行设备降落；或者，若飞行设备未落入目标限飞区且飞行设备与目标限飞区的距离小于等于预设阈值，则控制飞行设备远离目标限飞区；或者，若飞行设备未落入目标限飞区且飞行设备与目标限飞区的距离小于等于预设阈值，则控制飞行设备降落或悬停。
举例说明，假设flysafe模块需要的限飞区数据为地址从501-1500(每一地址对应1Byte的数据)的共计1KB的数据，则flysafe模块将该1KB的数据的地址以及长度发送给agent模块。agent模块根据数据库头部信息可以获知该部分限飞区数据所属目标数据块为数据块1(包括地址从1-1000的数据)和数据块2(包括地址从1001-2000的数据)。agent模块向存储设备分别发送7次获取请求依次获取7次目标数据块中的部分数据，该过程具体可以是：agent模块向存储设备发送携带地址1以及长度300的获取请求，存储设备根据该获取 请求向agent模块发送地址从1至300的数据，agent模块接收地址从1至300的数据。agent模块向存储设备发送携带地址301以及长度300的获取请求，存储设备根据该获取请求向agent模块发送地址从301至600的数据，agent模块接收地址从301至600的数据。agent模块向存储设备发送携带地址601以及长度900的获取请求，存储设备根据该获取请求向agent模块发送地址从601至900的数据，agent模块接收地址从601至900的数据。agent模块向存储设备发送携带地址901以及长度1200的获取请求，存储设备根据该获取请求向agent模块发送地址从901至1200的数据，agent模块接收地址从901至1200的数据。agent模块向存储设备发送携带地址1201以及长度300的获取请求，存储设备根据该获取请求向agent模块发送地址从1201至1500的数据，agent模块接收地址从1201至1500的数据。agent模块向存储设备发送携带地址1501以及长度1800的获取请求，存储设备根据该获取请求向agent模块发送地址从1501至1800的数据，agent模块接收地址从1501至1800的数据。agent模块向存储设备发送携带地址1801以及长度200的获取请求，存储设备根据该获取请求向agent模块发送地址从1801至2000的数据，agent模块接收地址从1801至2000的数据。agent模块将该7次接收到的全部数据重新拼接成一个完整的数据块。然后agent模块根据该数据块，计算该数据块在数据库中对应的签名的地址，并向存储设备请求该签名。agent模块对拼接后的数据块计算签名，并与从存储设备请求到的签名做比对，如果一致则读取成功向flysafe模块返回地址为500-1500的数据，同时做缓存存储。flysafe模块收到读取成功的数据，按格式进行数据解析后，进行限飞功能的逻辑运算。
可选的，图6所示实施例中AP侧提供的是简单的文件读取的通用功能，还可以由远端服务器或者地面站代替AP完成限飞数据库的存储功能。
可选的，数据库可以不存放在一个存储设备中，一个数据库可以拆分存储，由代理模块负责向不同存储设备去请求数据。
实施本申请实施例，可以不必增加FC与AP间的带宽要求，可以很好的适配现有机型的硬件条件，同时对于将来不同机型不同硬件的不同链路带宽，只需要修改代理模块的链路配置即可，不需要修改AP侧的限飞数据库，不需要修改安全飞行模块的限飞功能逻辑代码，限飞功能逻辑和数据库设计都能有很大自由度。同时因为代理机制中会对目标数据块做缓存，读取之前会先查找自己的缓存中是否有，所以可以避免短时间内的重复读取，降低链路负担。
