具体实施方式
为了便于理解，下面首先介绍一下本申请实施例涉及到的技术术语。
需要说明的是，本申请实施例所述的第一通信协议为终端设备采集自身数据和/或将采集的数据发送给服务器的规则，示例性地，该第一通信协议可以是CAN总线通信协议等。后面实施例的描述中主要以第一通信协议为CAN总线通信协议为例进行介绍，这不构成对本申请的限制，本申请中所述的第一通信协议可以是满足“第一通信协议为终端设备采集自身数据和/或将采集的数据发送给服务器的规则”这一定义的其它的通信协议。
1、控制器局域网络(controller area network，CAN)
CAN被设计作为汽车环境中的微控制器通讯***，在车载的各个部件之间交换信息，形成汽车电子控制网络。比如：发动机管理***、变速箱控制器、仪表装备、电子主干***等部件中，均嵌入CAN控制装置。
CAN的高性能和可靠性已被认同，除了汽车领域，CAN还被广泛地应用于工业自动化、船舶、医疗设备、工业设备等方面。现场总线是当今自动化领域技术发展的热点之一，被誉为自动化领域的计算机局域网。它的出现为分布式控制***实现各节点之间实时、可靠的数据通信提供了强有力的技术支持。
2、CAN数据
CAN数据就是终端设备(关于终端设备的描述可以参见下面图2中的相关描述)中通过CAN总线采集到的该终端设备各个部件的数据。为了便于理解，以终端设备为车辆为例介绍，对于车辆，其通过CAN总线采集到的CAN数据例如可以包括右后胎指示器状态有效性、快速漏气指示器状态、快速漏气指示器状态有效性、左前胎压值、左前胎压值有效性、左前胎温值、左前胎温值有效性、右前胎压值、右前胎压值有效性、右前胎温值、右前胎温值有效性、左后胎压值、左后胎压值有效性、左后胎温值有效性、右后胎压值、右后胎压值有效性、右后胎温值和右后胎温值有效性等等。
3、数据传输对象(data transfer object，DTO)
数据传输对象DTO是一种数据的格式，目的为进行数据封装，实现层与层之间的数据传递。
4、子码(subcode)
在本申请中，subcode指的是对一个数据的二进制编码，通过该二进制编码可以在服务器解析数据时匹配到唯一的DTO字段。
5、采集周期
在本申请中，采集周期指的是终端设备通过CAN总线采集自身各个部件的数据的周期。例如，终端设备每隔1毫秒采集一次数据，那么采集周期为1毫秒。
不同的部件的数据的采集周期可以不同，或者也可以相同。本申请对采集周期的取值不做限定。
6、上报周期
在本申请中，上报周期指的是终端设备将通过CAN总线采集到的数据发送给服务器(关于服务器的描述可以参见下面图2中的相关描述)的周期。例如，终端设备每隔10毫秒向服务器发送一次数据，那么上报周期为10毫秒。本申请对采集周期的具体取值不做限定。
7、CAN数据二进制码流
终端设备向服务器发送的CAN数据是二进制码流的形式，即终端设备将采集到的多个CAN数据分别编码得到各个CAN数据对应的二进制数据，然后，将这些二进制数据拼接在一起得到一个二进制码流，并将该二进制码流发送给服务器。为了便于理解该CAN数据的二 进制码流，示例性地，可以参见图1。
图1示例性示出了终端设备向服务器发送的二进制码流中CAN数据部分的二进制码的示意图。图1中以上报的CAN数据包括3个采集周期采集到的CAN数据为例说明，本申请对具体实施例中每次上报的数据包括的采集周期的个数不做限制。可以看到每个采集周期对应的二进制码中都包括数据数量和采集周期的信息，各占2个字节的长度。该数据数量指的是在对应的采集周期内上报的数据的个数，以采集周期1为例，该采集周期1内采集到的数据包括多个，分别以数据标识例如1.1、1.2等等来标记各个数据。每个数据占二进制码流的长度根据通信协议的规定确定，本方案对此不做限制。另外，在图1中还可以看到每个数据都对应有1位的有效位，用于指示该数据是否有效，示例性地，若该有效位为1表示该数据无效，若该有效位为1表示该数据有效。
为了更好的理解本申请实施例提供的一种数据通信处理方法，下面对本申请实施例适用的场景进行示例性地介绍。
参见图2，图2示例性示出了一种本申请提供的数据通信处理方法使用的***架构图。该***架构可以包括一个或多个(图2中以n2个为例示出)服务器210、多个(图2中以n3个为例示出)终端设备220和多个(图2中以n1个为例示出)管理设备230。其中，终端设备220和管理设备230可以与服务器210交互通信。多个服务器210可以组成服务器集群，或者组成数据中心等***。该n1、n2和n3可以是大于1的整数。
服务器210可以用于从终端设备220获取终端设备220的数据，以便于分析终端设备220的状态。示例性地，服务器210可以是一个物理服务器或者云服务器等。服务器210中部署有通信接口用于与管理设备230和终端设备220进行通信。例如，服务器210中部署有添加(post)接口、修改(put)接口、查询(get)接口和删除(delete)接口等。其中，管理设备230可以调用该post接口向服务器210发送通信协议等；管理设备230可以调用该put接口修改已经存储在服务器210中的通信协议等；管理设备230可以调用该get接口向服务器210查询数据等；管理设备230可以调用该delete接口删除存储在服务器210中的数据等。
另外，服务器210中还部署有用于处理管理设备230发送过来的数据以及处理终端设备220发送过来的数据的应用程序或软件平台，示例性地，该应用程序或者软件平台可以是一种物联网管理***：海量连接(ocean connect，OC)软件平台。
终端设备220中的传感器、电机、仪器仪表等设备可以通过CAN总线连接，终端设备220可以通过CAN总线采集到自身各个部件的状态数据，这些数据可以称为CAN数据。终端设备220可以将采集到的CAN数据发送给服务器210，然后服务器210可以基于这些CAN数据分析终端设备220的状态。示例性地，终端设备220可以是车辆、路侧单元、船只、机器人或者数控机床设备等等，只要是通过CAN总线采集自身的数据发送给服务器210的设备都属于本申请所述的终端设备。
管理设备230可以是用于管理终端设备220的服务器，管理设备230上面部署了用于管理终端设备220的应用程序或软件等。管理设备230可以用于管理终端设备220的各种信息，例如终端设备220的标识、上线状态、健康状态、所属的用户以及终端设备220使用的CAN总线通信协议等信息。在本申请中，管理设备230还可以向服务器210发送终端设备220使用的CAN总线通信协议，服务器210可以存储该协议，以便于后续解析终端设备220发送来的CAN数据。示例性地，假设终端设备220为汽车，管理设备230可以是该汽车的生产制造企业中的管理设备等，或者管理设备230可以是第三方的管理设备等。
在本申请中，终端设备220可以包括多种类型，或者多种生产制造商生产制造的终端设备，管理设备230也可以对应地包括多种生产制造商的管理设备等等。
随着技术的不断发展，不同的生产制造商生产的终端设备220所使用的CAN总线通信协议不一定相同，即各个生产制造商可以有各自推出的CAN总线通信协议使用在各自生产制造的终端设备上。在这种情况下，服务器210从不同生产制造商的终端设备220接收到的CAN数据可以是基于不同的CAN总线通信协议采集并上报的，服务器210需要基于不同的CAN总线通信协议解析接收到的不同的CAN数据。在本申请中，上报数据指的是终端设备向服务器发送的CAN数据。
通常，服务器210上通过部署CAN数据的解析代码来实现对接收到的CAN数据的解析，但是该代码只能解析一种CAN总线通信协议的数据，若想解析多种不同的CAN总线通信协议的数据，则需要部署多套代码，导致需要耗费大量的人力物力，同时对服务器210的存储资源和计算资源占用过多，另外，由于需要部署多套解析代码，需要较长的研发时间，极大地制约服务上线的效率。为了解决这些问题，本申请提供了一种数据通信处理方法，能够低成本且灵活地解析终端设备通过各种不同的CAN总线通信协议上报的数据。
参见图3，本申请提供的一种数据通信处理方法可以应用于上述图2所示的场景中，该方法可以包括但不限于如下步骤：
301、服务器获取配置文件和第一车辆的标识，该配置文件用于配置第一通信协议，该第一车辆的标识关联该第一通信协议；该第一通信协议为该第一车辆采集自身数据和/或将采集的数据发送给该服务器的规则。
示例性地，该服务器例如可以是上述图2所示的服务器210，该第一车辆可以是上述图2所示的终端设备220。
服务器中以配置文件的形式配置了多个不同的通信协议，这些通信协议均为车辆等终端设备采集自身数据和/或将采集的数据发送给该服务器的规则。另外，在服务器中各个车辆的标识与该车辆所采用的通信协议关联，以便于通过车辆的标识可以查找到该车辆采用的通信协议。
需要说明的是，该通信协议对应的配置文件包括该通信协议的内容，对于服务器来说，通信协议的配置文件即为该通信协议。可选的，下面图7和图8中所描述的管理设备(例如上述图2所示的管理设备230)向服务器发送的通信协议可以是该通信协议的配置文件。
以上述第一车辆和第一通信协议为例，上述服务器中预先配置了上述第一车辆采用的通信协议即该第一通信协议。可选的，服务器可以从管理设备接收到该第一通信协议的配置文件，然后将该配置文件存储在数据库中。或者，可选的，服务器可以通过自身的输入设备获取到该第一通信协议的配置文件，例如，工作人员直接将该第一通信协议的内容输入到该服务器中形成配置文件的情况。
服务器获取到上述第一通信协议之后，可以生成该第一通信协议的标识发送给管理设备，管理设备将第一车辆的注册信息发送给服务器，该注册信息中包括该第一通信协议的标识和该第一车辆的标识，然后，服务器将该第一车辆的标识与该第一通信协议关联，以便于后续的查询。具体的实现过程可以参见下面对图7对应的描述，此处暂不详述。
一种可能的实施方式中，上述服务器获取的第一通信协议的配置文件携带在管理设备发送的第一车辆的注册信息中，该注册信息中还包括该第一车辆的标识，那么，服务器接收到该注册信息之后，可以将该第一车辆的标识与该第一通信协议关联，以便于后续查询。具体的实现过程可以参见下面对图8对应的描述，此处暂不详述。
在服务器中关联了第一车辆的标识和第一通信协议之后，第一车辆可以与服务器建立通信连接，并将该第一车辆自身的标识发送给服务器，以用于获取对应的通信协议的数据格式。
302、该服务器基于该第一车辆的标识，查找该第一通信协议。
服务器与上述第一车辆建立通信连接，并从第一车辆接收到该第一车辆的标识之后，基于该第一车辆的标识查找到该第一车辆所采用的第一通信协议。然后，基于该第一通信协议生成对应的数据格式要求下发给该第一车辆，该第一车辆基于该数据格式要求采集并上报数据给服务器。服务器接收到第一车辆采集上报的数据之后，可以找到该第一车辆采用的第一通信协议，基于该第一通信协议完成对该数据的解析。具体的实现过程可以参见下面对图5对应的描述，此处暂不详述。
参见图4，本申请提供另一种数据通信处理方法，该方法可以应用于上述图2所示的场景中，该方法可以包括但不限于如下步骤：
401、服务器获取配置文件和第一通信协议的标识，该配置文件用于配置该第一通信协议；该第一通信协议为第一车辆采集自身数据和/或将采集的数据发送给该服务器的规则。
示例性地，该服务器例如可以是上述图2所示的服务器210，该第一车辆可以是上述图2所示的终端设备220。
在本申请实施例中，服务器可以从管理设备(例如上述图2所示的管理设备230)接收到该第一通信协议的配置文件，将该配置文件存储在数据库中。需要说明的是，该通信协议对应的配置文件包括该通信协议的内容，对于服务器来说，通信协议的配置文件即为该通信协议。
可选的，服务器接收到上述第一通信协议后，可以生成该第一通信协议的标识，将该标识与该第一通信协议关联，并将该标识发送给管理设备，然后，将该第一通信协议的标识存储在该第一车辆中。示例性地，可以是在生产该第一车辆时将该第一通信协议的标识存储在该第一车辆中，或者可以是管理设备将该第一通信协议发送给该第一车辆并存储等等。
或者，可选的，第一通信协议的标识无需服务器生成，而是由管理设备发送给服务器，例如，管理设备向服务器发送第一通信协议时将该第一通信协议的标识一起发送给服务器。然后，服务器将该第一通信协议的标识与该第一通信协议关联并存储，以用于后续的查询。另外，该第一通信协议的标识还存储在第一车辆中。示例性地，可以是在生产该第一车辆时将该第一通信协议的标识存储在该第一车辆中，或者可以是管理设备将该第一通信协议发送给该第一车辆并存储等等。
在服务器中关联了第一通信协议的标识和该第一通信协议之后，第一车辆可以与服务器建立通信连接，并将该第一车辆自身存储有的第一通信协议的标识发送给服务器，以用于获取对应的通信协议的数据格式。
402、该服务器基于该第一通信协议的标识查找该第一通信协议。
服务器从第一车辆接收到第一通信协议的标识之后，基于该第一通信协议的标识查找到该第一车辆所采用的第一通信协议。然后，基于该第一通信协议生成对应的数据格式要求下发给该第一车辆，该第一车辆基于该数据格式要求采集并上报数据给服务器。服务器接收到第一车辆采集上报的数据之后，可以找到该第一车辆采用的第一通信协议，基于该第一通信协议完成对该数据的解析。具体的实现过程可以参见下面对图5对应的描述，此处暂不详述。
上述图4所示的实施例相比于上述图3所示的实施例，服务器中可以不用将第一通信协议与车辆的信息例如车辆的标识关联，那么服务器中可以不存储车辆的相关信息，从而可以节省服务器的存储资源。
一种可能的实施方式中，上述图3和图4所示的实施例中，服务器中不同的通信协议的 配置文件均可以通过预设模型的形式存储在服务器中。该预设模型包括多种不同通信协议中的数据种类的表达形式。示例性地，该预设模型的具体形式可以参见下面表1和表2。
表1
名称 是否必选 类型 说明
id Y string 通信协议的唯一标识
report period Y integer 数据上报周期
data format Y list<data format> 各个CAN数据的格式的具体描述
表1示例性示出了本申请提供的一种在服务器中统一表达各种不同的通信协议的预设模型，可以看到，该预设模型中包括通信协议的唯一标识，该标识即为上述提到的通信协议的标识。该通信协议的标识的类型要求为字符串(string)类型。
该预设模型中还包括采用该通信协议的终端设备将CAN数据发送给服务器的周期，称为上报周期(report period)。该上报周期的类型要求为整数(integer)型。
该预设模型中还包括采用该通信协议的终端设备中的各个CAN数据的格式的具体描述。每一个CAN数据的格式的描述可以是以列表(list)的形式来表示。示例性地，可以参见表2，表2为本申请提供的预设模型中CAN数据的格式的list。
表2
Figure PCTCN2021133280-appb-000001
Figure PCTCN2021133280-appb-000002
在表2中可以示例性地看到预设模型中CAN数据的格式要求。需要说明的是，上述表2中的“是否必选”中，Y表示通信协议中必须包括对应的内容，N表示通信协议中可以包括或者不包括对应的内容。表2中除了规定终端设备采集和上报CAN数据的格式，还给出了各项内容对应的约束，约束指的是需要满足的条件。下面逐一解释表2中的各项内容：
数据标识(data id)：指的是上报的CAN数据的标识，CAN数据的标识的类型可以为string型。例如，假设终端设备为车辆，车辆上报的CAN数据包括右后胎指示器状态有效性、快速漏气指示器状态、快速漏气指示器状态有效性、左前胎压值、左前胎压值有效性，那么这些CAN数据的标识依次可以是“1”、“2”、“3”、“4”和“5”。
另外，在约束中可以看到，要求上报的所有的CAN数据的标识为连续的整数。可选的，在具体实施例中，上述上报的所有的CAN数据的标识也可以约束为连续的字母等字符，或者约束为有规律的字符的组合(例如图1所示的数据标识)等，本申请对此不作限制。
数据种类(type)：指的是CAN数据的数据种类，可以包括有效性(valid)数据种类、状态(status)数据种类、数值(value)数据种类和字符串(string)数据种类。其中：
valid数据种类，用于描述终端设备的部件的状态或数据的有效性。例如，可以约定，用数值0表示无效(invalid)，用数值1表示有效(valid)。例如，假设终端设备的部件为右后胎指示器，对于该右后胎指示器的状态，可以用1表示该指示器的状态有效，0表示该指示器的状态无效。对于右后胎的温度值，也可以用1表示该温度值有效，0表示该温度值无效。
约束中要求该valid数据种类的数据长度为1。可选的，在具体实施例中该描述有效性的数据长度也可以约束为其它的长度，例如2或3等等，本申请对此不做限制。
status数据种类，用于描述终端设备的部件的状态，可以以枚举的形式体现。该描述部件状态的数据的长度可以为1。例如，对于门的状态，一般是两个状态：关闭(closed)状态和开启(open)状态，那么，可以用0表示门的closed状态，可以用1表示门的open状态。又例如，对于快速漏气指示器的状态，其有两种状态，分别为不快速漏气(not fast leakage)状态和快速漏气(fast leakage)状态，那么，可以用0表示not fast leakage状态，可以用1表示fast leakage状态。
约束中要求status数据种类的数据的长度必须不大于该数据长度所能表示的最大枚举个数，且枚举的状态都可以在DTO属性中找到对应枚举字段。DTO属性为服务器将终端设备上报的CAN数据解析后得到的DTO格式的数据的属性。枚举的状态都可以在DTO属性中找到对应枚举字段的这个要求，可以保证解析的每一个状态都有对应的DTO字段。
为了便于理解，示例性地，例如，假设左后门状态的数据长度为1，则最大枚举个数为2，可以用0表示该左后门的closed状态，可以用1表示该左后门的open状态，因而可以在通信协议和上述基于通信协议转换得到的数据格式要求中添加该两个状态的表示数值；且DTO属性左后门(left rear door)的枚举类型必须包括closed和open两种状态。
又例如，假设轮胎温度的数据长度为2，则最大枚举个数为4，而轮胎温度对应状态共3个，包括一般(normal)、高(high)和预留(reserved)这三个状态，可以用0表示normal，用1表示high，用2或3表示reserved状态，因而可以在通信协议和上述基于通信协议转换得到的数据格式要求中添加该两个状态，则在解码过程中。且DTO属性中轮胎温度的枚举类型必须包括normal、high和reserved这三种状态，这样服务器解析终端设备上报的轮胎温度时可以基于0＝normal、1＝high和2～3＝reserved这一规则来解析。
value数据种类，用于描述终端设备的部件的在某些方面的具体的数值，例如用于描述通过传感器采集到的部件的温度和压力的具体数值等等。在服务器解析终端设备上报的CAN数据的过程中，value数据种类的数据需要先将上报的二进制数据转换为十进制数据，再根据通信协议中规定的精度和偏移量进行计算，得到对应的数值，该计算得到的数值需要不小于规定的最小值，且不大于规定的最大值。计算方法如式(1)所示。
value＝accuracy*data+offset               (1)
式(1)中，accuracy表示精度，offset表示偏移量，data表示根据二进制码流获得的十进制数值，value表示计算得到的最终数据。需要注意的是，value必须位于通信协议规定的范围之内。
约束中要求value数据种类的数据的最大值必须不大于规定的最大值，且要求value数据种类的数据的最小值必须不小于规定的最小值。为了满足这个约束，根据数据长度、精度、偏移量计算得到的最大值必须不大于规定的最大值，且计算得到的最小值必须不小于规定的最小值，即需要满足如下式(2)和式(3)的关系：
minimum≥offset            (2)
maximum≤D*accuracy+offset            (3)
其中，minimum表示数据的最小值，maximum表示数据的最大值。假设数据的二进制长度为L，则D表示该二进制数据转换成十进制数据后的最大值，即D＝2^L-1。例如，假设数据的二进制长度为7，则D＝2^7-1＝127。由于value数据种类的数据是通过上述式(1)计算得到，因此可知，该value数据种类的数据规定的最小值为data为0时计算得到的值，即为offset；该value数据种类的数据规定的最大值为data为上述D时计算得到的值，即为D*accuracy+offset。
在表2中可以看到，若描述的CAN数据为value数据种类的数据，那么，约束中要求最大值(maximum)、最小值(minimum)、精度(accuracy)和偏移量(offset)这几个参数是必须在通信协议中明确说明的。
若描述的CAN数据为status数据种类的数据，那么，约束中要求在通信协议中明确说明该CAN数据为status数据种类的数据。
对于子码(subcode)，由于服务器需要通过subcode匹配到唯一的DTO字段，因此，约束中要求终端设备上报的所有CAN数据的subcode不能重复，即每个CAN数据都有唯一的subcode。
string数据种类，可用于描述终端设备采集的该终端设备自身的生产制造商、类型等数据，也可用于描述采集的错误码和错误信息等，还可用于传输其他文本信息等。
在表2中，若描述的CAN数据为valid数据种类的数据，那么，终端设备上报该CAN数据的长度为1。
假设终端设备上报的二进制码流的各个二进制位从左到右排列，那么，该二进制码流中的某个CAN数据的二进制码的最高位不能在最低位的右侧，最低位不能在最高位的左侧。为了便于理解，示例性地，可以参见图1，以图1中的数据1.1为例说明。假设数据1.1的二进制码为10011010，位数为8位，且该数据1.1占用上报的二进制码流中的第p位至第p+7这8位，那么，在规定该数据1.1的二进制码在上报的二进制码流中的位置时可以这样规定：数据1.1的最高位为第p位，最低位为第p+7位。而不能规定为数据1.1的最高位为第p+7位，最低位为第p位。
另外，由最高位和最低位计算得到的数据长度必须与上报数据长度一致。
一个CAN数据的采集周期须要可以整除该CAN数据的上报周期，即上报周期为采集周期的整数倍。
可选的，在表2中采集周期相同的数据，其数据标识是连续的。例如，采集周期为500毫秒的数据有三个，采集周期为200毫秒的数据有两个，则该三个采集周期为500毫秒的数据的标识可以设置为连续的例如1、2和3，另外，两个采集周期为200毫秒的数据的标识也可以设置为连续的例如4和5。若采集周期为500毫秒的数据的标识设置为1、3和4，而采集周期为200毫秒的数据的标识设置为2和5，则是不符合规则的。
终端设备上报的二进制码流中，各个CAN数据的上报区间不能有重叠。为了便于理解，还是以图1为例介绍。以数据1.1和数据1.2示例，数据1.1的上报区间可以是数据1.1的二进制码和有效位占用的区间，数据1.2的上报区间为数据1.2的二进制码和有效为占用的区间，该两个区间之间不能占用相同的位数。例如，数据1.1的上报区间占用的位数为第p位至第p+9位，那么，数据1.2的上报区间占用的位数为第p+10位至第p+19位是合理的，但是，假如数据1、2的上报区间占用的位数为第p+9位至第p+18位则是不合理的，因为两个数据都占用了第p+9位，导致无法正确解析出该两个数据。
另外，在服务器向终端设备下发数据格式要求的报文中也是以二进制码流的形式在传输，该下发的数据格式也包括了多个CAN数据的采集要求和上报要求，同样地，本申请的数据格式约束中要求该下发的数据格式的二进制码流中各个CAN数据的数据格式的要求所占用的二进制位不能重叠。
假设服务器向终端设备下发的数据格式要求的二进制码流的各个二进制位从左到右排列，那么，该二进制码流中的某个CAN数据的数据格式要求的二进制码的最高位不能在最低位的右侧，最低位不能在最高位的左侧，且由最高位和最低位计算得到的数据长度必须与采 集数据长度一致。
上述主要基于表1和表2示例性地介绍了本申请提供的一种在服务器中统一表达各种不同的通信协议的预设模型，需要说明的是，上述所述的预设模型仅为一个示例，在具体实施例中的预设模型不限于上述所介绍的内容。
为了更好地理解本申请提供的一种数据通信处理方法，下面基于设备之间的交互流程图进一步介绍。
参见图5，图5所示为终端设备从服务器获取对应通信协议的数据格式要求并上报数据的交互流程，可以包括但不限于如下步骤：
501、终端设备和服务器交互建立通信连接。
在具体实施例中，终端设备可以是上述图2所示的终端设备220，服务器可以是上述图2所示的服务器210。
终端设备可以向服务器发送连接请求，用于请求服务器与自身建立通信连接。该连接请求可以包括终端设备的标识。示例性地，假设终端设备为车辆，那么车辆的标识可以包括车辆的出厂编号、车辆识别号码(vehicle identification number，VIN)或者车辆的车牌号等。
服务器接收到该连接请求之后，可以向终端设备返回一个连接建立的响应消息，从而完成终端设备和服务器之间通信连接的建立。
502、服务器查找第一通信协议。
在终端设备和服务器建立通信连接之后，由于在本申请中，不同的终端设备可能采用不同的通信协议采集/上报自身的数据给服务器，为了快速灵活地解析基于不同通信协议上报的数据，服务器需要向终端设备下发终端设备采集/上报数据的数据格式要求，规定终端设备采集/上报数据的数据格式。该数据格式要求是基于终端设备采用的通信协议转换得到的(下面步骤303中会详细介绍，此处暂不详述)，因此，服务器需要先查找到终端设备对应采用的通信协议。
具体的，该第一通信协议为终端设备采用的CAN总线通信协议。在具体实施例中，服务器中存储有多种CAN总线通信协议，且这些CAN总线通信协议都有各自的协议标识，可以在服务器中唯一标识不同的通信协议，即通过协议标识可以查找到唯一对应的CAN总线通信协议。
一种可能的实施方式中，上述服务器查找第一通信协议的具体实现可以是：服务器中将终端设备的标识与该终端设备采用的CAN总线通信协议的标识关联，那么，服务器可以通过该终端设备的标识查找到其使用的通信协议的标识，进而通过该协议的标识查找到该第一通信协议。或者，服务器中将终端设备的标识与该终端设备采用的CAN总线通信协议直接关联，那么，服务器可以通过该终端设备的标识可以直接查找到该第一通信协议。该服务器中存储的终端设备的标识可以是管理设备向服务器注册该终端设备的信息时发送给该服务器的(具体可以参见下面图7和图8所示实施例的描述，此处暂不详述)。另外，上述终端设备和服务器交互建立通信连接的过程中服务器可以获取到该终端设备的标识，从而可以查找到该第一通信协议。
另一种可能的实施方式中，上述服务器查找第一通信协议的具体实现可以是：上述连接请求中包括了该终端设备采用的CAN总线通信协议的标识，或者，服务器和终端设备建立连接之后，终端设备另外向服务器发送了该终端设备采用的CAN总线通信协议的标识，那么，服务器可以基于从该终端设备中接收到的该终端设备采用的CAN总线通信协议的标识，查找 到上述第一通信协议。
503、服务器基于该第一通信协议向终端设备发送数据格式要求。
具体的，该数据格式要求用于规定该终端设备采集的数据和/或向服务器发送的数据的格式。
在具体实施例中，终端设备通过CAN总线采集数据，是基于其采用的CAN总线通信协议来采集的，采集完数据之后，需要将采集的CAN数据转换成二进制码流发送给服务器，该CAN数据转换成二进制码流也是基于终端设备采用的CAN总线通信协议来转换的。即，终端设备通过CAN总线采集的CAN数据的数据格式，以及终端设备向服务器发送的二进制码流的格式都是遵循该终端设备所采用的CAN总线通信协议中的规定来确定的。
基于上述的描述，由于服务器后续需要解析终端设备发送的CAN数据的二进制码流，那么为了便于服务器解析，服务器可以将终端设备采用的CAN总线通信协议按照预设规则转换成数据格式要求。然后，服务器将转换得到的数据格式要求发送给终端设备，以使得终端设备按照该数据格式的要求采集数据和发送数据。
需要说明的是，上述预设规则适用于服务器中存储的所有CAN总线通信协议，包括上述第一通信协议。即，服务器可以将该所有的CAN总线通信协议按照该预设规则转换成这些CAN总线通信协议各自对应的数据格式要求。
为了便于理解上述预设规则，可以参见上述表1和表2。上述预设规则要求通信协议中明确上报周期(report period)。且该上报周期的类型要求为整数(integer)型。上述预设规则还要求通信协议中明确采用该通信协议的终端设备中的各个CAN数据的格式的具体描述。每一个CAN数据的格式的描述可以参见上述表2。在表2中可以看到，预设规则可以规定终端设备采集和上报CAN数据的格式和约束。关于该格式和约束的描述可以参见上述对表2的具体描述，此处不再赘述。
上述主要基于表1和表2示例性地介绍了上述服务器将通信协议转换成数据格式要求的预设规则，需要说明的是，上述所述的预设规则仅为一个示例，在具体实施例中的预设规则不限于上述所介绍的内容。
服务器按照上述预设规则将上述终端设备采用的通信协议即第一通信协议转换成数据格式要求后，将该数据格式要求发送给终端设备。
504、终端设备基于该数据格式要求采集第一数据。
终端设备接收到服务器发送的数据格式要求之后，解析获取对应的内容，然后基于对应的数据格式通过CAN总线采集自身中的各个部件的数据。
505、终端设备基于该数据格式要求向服务器发送该第一数据。
终端设备采集得到CAN数据之后，按照数据格式要求中各个CAN数据的上报格式要求，生成CAN数据的二进制码流，可以称该生成的CAN数据的二进制码流为第一数据，然后，终端设备向服务器发送该第一数据。
506、服务器接收该第一数据，并基于第一通信协议解析该第一数据。
服务器接收来自终端设备的第一数据之后，首先可以查找到该终端设备对应的第一通信协议，然后，基于该第一通信协议解析该第一数据得到实际上报的终端设备的CAN数据，这些CAN数据可以指示终端设备中对应的部件的状态等情况。然后，服务器可以基于解析得到的CAN数据分析终端设备的状态，并将终端设备的状态实时地保存到数据库中。
具体的，由于该第一通信协议已经规定了该终端设备上报的各个CAN数据在二进制码流中的位置以及数据的长度，因此，服务器接收到终端设备上报的二进制码流即上述第一数据 之后，根据该第一通信协议即可解析出各个CAN数据的二进制数据，然后，按照上述式(1)计算出实际的CAN数值，每个CAN数值都对应某一种状态信息等，从而可以获知终端设备的对应的部件的状态等情况。
可选的，管理设备(例如图1所示的管理设备230)可以与服务器交互，获取服务器中存储的终端设备的状态信息。示例性地，可以参见图6。在图6中，上述步骤506、服务器接收该第一数据，并基于第一通信协议解析该第一数据之后，还可以包括但不限于如下步骤：
507、管理设备向服务器发送该终端设备的状态查询请求。
该状态查询请求中可以包括该终端设备的标识。
508、服务器基于该状态查询请求获取该终端设备的状态信息。
服务器接收到该状态查询请求之后，解析得到该终端设备的标识，通过该标识在数据库中查找到该终端设备最新的状态信息。
509、服务器向管理设备发送该终端设备的状态信息。
服务器获取到该终端设备最新的状态信息之后，将其封装成报文发送给管理设备。管理设备可以通过该终端设备的状态信息了解该终端设备的状态，以便于做出相应的判断和控制，例如，可以判断终端设备是否异常，若异常，则需要提醒用户，以减少意外的损害等等。
一种可能的实施方式中，上述服务器接收到终端设备上报的CAN数据之后，也可以不对这些数据进行分析，可以直接将接收到的数据存储在数据库中。然后，管理设备可以与服务器交互获取到终端设备的CAN数据，然后，由管理设备基于这些CAN数据分析对应终端设备的状态。
一种可能的实施方式中，上述步骤502中所述的服务器中将终端设备的标识与该终端设备采用的CAN总线通信协议的标识关联，或者服务器中将终端设备的标识与该终端设备采用的CAN总线通信协议直接关联，可以通过图7所示的实施方式来实现。参见图7，可以包括但不限于如下步骤：
701、管理设备向服务器发送上述第一通信协议。
在具体实施例中，管理设备可以配置终端设备采用的通信协议，下面还是以终端设备采用的通信协议为第一通信协议为例介绍。
管理设备可将终端设备采用的第一通信协议发送给服务器，以用于存储在服务器中。
示例性地，管理设备可以调用服务器的post接口将该第一通信协议发送给服务器。
702、服务器接收该第一通信协议，并生成该第一通信协议的标识。
服务器接收到该第一通信协议之后，由于服务器要管理多个不同的通信协议，为了便于管理，可以为每个通信协议配置一个唯一标识，因此，服务器可以为第一通信协议生成一个唯一标识。
703、服务器向管理设备发送该第一通信协议的标识。
管理设备接收到服务器发送的第一通信协议的标识之后，可以将该第一通信协议的标识关联到采用该第一通信协议的终端设备的信息中。
704、管理设备向服务器发送上述终端设备的注册信息，该注册信息包括该终端设备的标识和第一通信协议的标识。
终端设备与服务器建立通信连接之前，管理设备需要将终端设备的信息注册到服务器中。因此，管理设备可以向服务器发送终端设备的注册信息，该注册信息可以包括该终端设备的 标识、该终端设备所属的用户的信息、该终端设备的相关状态以及该终端设备所采用的通信协议即第一通信协议的标识等信息。需要说明的是，该终端设备的注册信息可以包括该终端设备相关的任意信息，本申请对此不做限制。
705、服务器基于该注册信息完成注册，并关联该终端设备的标识、第一通信协议的标识和该第一通信协议。
服务器接收到上述注册信息之后，基于该注册信息完成该终端设备的注册操作，该注册操作例如可以是将该注册信息存储在数据库等等，本申请对此不做限制。另外，服务器还将注册信息中终端设备的标识、第一通信协议的标识与服务器中已经存储的第一通信协议关联，以便于后续查找。
可选的，服务器也可以是基于该第一通信协议的标识查找到该第一通信协议，仅将该第一通信协议的标识和该第一通信协议进行关联。
706、服务器向管理设备发送注册响应信息。
服务器完成注册之后，向管理设备发送一个注册完成的响应信息，以告知管理设备完成了注册。
一种可能的实施方式中，上述步骤502中所述的服务器中将终端设备的标识与该终端设备采用的CAN总线通信协议的标识关联，或者服务器中将终端设备的标识与该终端设备采用的CAN总线通信协议直接关联，还可以通过图8所示的实施方式来实现。参见图8，可以包括但不限于如下步骤：
801、管理设备向服务器发送终端设备的注册信息,该注册信息包括该终端设备的标识和第一通信协议。
802、基于该注册信息完成注册，生成该第一通信协议的标识，并关联该终端设备的标识、第一通信协议的标识和该第一通信协议。
803、发送注册响应信息。
本申请实施例中，相比于上述图7所示的实施例，主要的区别是管理设备不单独将第一通信协议发送给服务器，而是将该第一通信协议携带在上述注册信息中，一起发送给管理设备，从而可以节省一些交互步骤，进而节省带宽资源和两个设备的计算资源。除了该区别之外，图8所示的其它步骤的具体实现参见上述对图7中所示的步骤的对应描述，此处不再赘述。
一种可能的实施方式中，上述图7和图8所示的实施例中，服务器在生成该第一通信协议的标识之前，可以先检查一下该第一通信协议是否符合预设的要求。具体的，服务器可以按照上述预设规则中的约束(例如表2中所示的约束)来检查该第一通信协议是否符合预设的要求，只有在第一通信协议符合预设要求的情况下，服务器才生成该第一通信协议的标识。如果该第一通信协议不符合预设要求，那么，服务器可以向管理设备发送一个指示该第一通信协议不合格的消息，例如直接返回一个错误消息等等。
一种可能的实施方式中，上述步骤502中所述的连接请求中包括了该终端设备采用的CAN总线通信协议的标识，或者，服务器和终端设备建立连接之后，终端设备另外向服务器发送了该终端设备采用的CAN总线通信协议的标识，可以通过如下两种可能的实施方式来实现：
第一种可能的实施方式：管理设备可以根据上述图7或图8所示的实施方式及其可能的实施方式获取到上述第一通信协议的标识，然后，该管理设备可以将该第一通信协议的标识 发送给上述终端设备，终端设备将该第一通信协议的标识存储起来。或者，由于该管理设备为生产制造商的管理设备，因此，终端设备在生产制造的过程中，该第一通信协议的标识就被存储于其中，而该第一通信协议的标识来自于上述管理设备从服务器接收到的标识。从而，在终端设备向服务器发送连接请求时，可以在连接请求中携带该第一通信协议的标识；或者，在服务器和终端设备建立连接之后，终端设备可以另外向服务器发送了该第一通信协议的标识。可选的，在本实施方式中，服务器中可以不用存储终端设备的标识与该第一通信协议的标识的映射关系，或者，不用存储该终端设备的标识与该第一通信协议的映射关系。
第二种可能的实施方式：在具体实施例中，管理设备向服务器发送第一通信协议，该第一通信协议可以是管理设备单独发送给服务器(例如可以参见上述图7所示的实施方式)，或者，该第一通信协议可以是管理设备将其携带在终端设备的注册信息中发送给服务器(例如可以参见上述图8所示的实施方式)。在本实施方式中，管理设备在向服务器发送第一通信协议的同时，还可以把该第一通信协议的标识一起发送给服务器，然后，服务器将该第一通信协议及接收到的协议标识关联，以备后续查询。在本实施方式中，通信协议的唯一标识是由管理设备提供的，而不是服务器生成的。这种情况下，管理设备可以提前就将第一通信协议的标识发送给终端设备，或者在生产该终端设备时将协议标识存储与其中。从而，在终端设备向服务器发送连接请求时，可以在连接请求中携带该第一通信协议的标识；或者，在服务器和终端设备建立连接之后，终端设备可以另外向服务器发送了该第一通信协议的标识。
需要说明的是，管理设备向服务器发送的第一通信协议的标识需要满足该标识是服务器中唯一的协议标识，否则，服务器还是可以重新为该第一通信协议生成一个新的唯一的标识。
一种可能的实施方式中，上述服务器接收到来自管理设备的第一通信协议及其协议标识，将其关联之前，可以先检查一下该第一通信协议是否符合预设的要求。具体的，服务器可以按照上述预设规则中的约束(例如表2中所示的约束)来检查该第一通信协议是否符合预设的要求，只有在第一通信协议符合预设要求的情况下，服务器才将该第一通信协议及其协议标识进行关联。如果该第一通信协议不符合预设要求，那么，服务器可以向管理设备发送一个指示该第一通信协议不合格的消息，例如直接返回一个错误消息等等。
综上所述，在本申请中，服务器中可以配置有多个不同的通信协议，并且将车辆所采用的通信协议与对应车辆的标识或该通信协议的标识关联，以使得服务器可以根据车辆的标识或该通信协议的标识明确车辆所采用的通信协议，从而能够基于车辆所采用的通信协议正确解析出车辆上报的数据。相比于现有的方案，本申请无需针对一个具体的通信协议部署复杂繁琐的解析代码，极大地节省了人力物力资源的同时，也节省了服务器的存储资源和计算机资源，且可以提高了服务上线的效率。另外，本申请中服务器所提供的数据解析服务，可以很好地适配各种不同的车辆生产制造商，具有很好地复用性。且，由于无需基于不同的协议部署不同的解析代码，从而无需频繁升级更新，具有更好的可维护性。
