 本发明的实施方式
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、技术之类的具体细节，以便透彻理解本申请实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本申请。在其它情况中，省略对众所周知的系统、汽车诊断设备、电路以及方法的详细说明，以免不必要的细节妨碍本申请的描述。
为了说明本申请所述的技术方案，下面通过具体实施例来进行说明。
图1示出了本申请实施例提供的汽车数据流显示方法的实现流程示意图，该方法应用于汽车诊断设备。参见图1所示，该方法的实现流程详述如下：
步骤S101，对无序显示的至少一条汽车数据流进行编号。
在本实施例中，无序显示的至少一条汽车数据流是指，所述汽车诊断设备将在预设时间段内读取到的汽车电子控制单元输出的汽车数据流，按照读取到汽车数据流的时间先后顺序排列显示或者随机排列显示的至少一条汽车数据流。
在本实施例中，在获取到汽车诊断设备无序显示的至少一条汽车数据流后，可根据所述汽车数据流的显示位置，对所述至少一条汽车数据流进行数字编号。例如：根据所述至少一条汽车数据流的显示位置，将所述至少一条汽车数据流从前往后分别编号为1、2、3、......、n。其中，n为与汽车数据流的数量相等的正整数。
步骤S102，对所述至少一条汽车数据流进行排序，并按照排序顺序显示所述至少一条汽车数据流。
在本实施例中，具体按照数据流标题的字母升序或降序对所述至少一条汽车数据流进行排序。其中，所述数据流标题为汽车数据流名称。所述汽车数据流名称为中文形式，或者英文形式。当汽车数据流名称为中文形式时，按照汽车数据流拼音首字母的升序或降序对所述至少一条汽车数据流进行排序；当汽车数据流名称为英文形式时，按照汽车数据流英文名称首字母的升序或降序对所述至少一条汽车数据流进行排序。
在本实施例中，由于汽车诊断设备按照数据流标题的字母升序或降序显示所述至少一条汽车数据流，使得读取到的汽车数据流由无序排列变为有序排列，这样可以方便用户快速从众多汽车流数据中查找到目标数据流。
步骤S103，接收目标数据流选择指令，根据所述目标数据流选择指令从所述至少一条汽车数据流中选取至少一条目标数据流。
在本实施例中，用户可根据目标数据流名称从有序排列的至少一条汽车数据流中选取需要查看的至少一条目标数据流。
优选的，所述汽车诊断设备的显示界面为触控显示屏，所述汽车诊断设备通过所述触控显示屏接收用户输入的目标数据流选择指令，当所述触控显示屏显示的某条汽车数据流所在位置检测到用户触摸操作，且所述触摸操作持续时间达到预设时间阈值时，则说明所述汽车数据流被选中，作为目标数据流。用户可从众多汽车数据流中选择多条数据流作为目标数据流。
步骤S104，对所述至少一条目标数据流进行分页显示。
在本实施例中，根据获取的目标数据流的总个数和预先设置的每页显示的数据流个数，对所述至少一条目标数据流进行分页显示。步骤S104具体包括：
根据获取的目标数据流的总个数和预设的每页显示的数据流个数计算出总页数；
按照数据流标题的字母升序或降序和所述预设的每页显示的数据流个数分配每页所对应显示的目标数据流；
根据分配结果对所述至少一条目标数据流进行分页显示。
优选的，在本实施例中，每页所对应的目标数据流均按照数据流标题的升序或降序进行排序显示。
其中，所述预设的每页显示的数据流个数为每页最多可以显示的数据流个数，其可由用户根据自身浏览习惯自行设定或修改。所述根据获取的目标数据流的总个数和预设的每页显示的数据流个数计算总页数具体包括：
利用所述目标数据流的总个数除以所述预设的每页显示的数据流个数，若结果为整数，则该整数即为总页数；若结果包括小数，则所述总页数为结果整数部分加一。例如：若所述预设的每页显示的数据流个数为10，所述目标数据流的个数为95，那么总页数为10，最后一页仅显示5条目标数据流，其余每页均显示10条数据流。
在本实施例中，由于在对所述至少一条目标数据流进行分页显示时，对每页所显示的目标数据流按照数据流标题的字母升序或降序进行显示，从而可以方便用户查阅，进一步提出了用户体验。
步骤S105，获取每页所显示的目标数据流的编号数据，建立显示页码与所述编号数据的关联关系。
在本实施例中，在对所述至少一条目标数据流进行分页显示后，需要获取每页所显示的目标数据流的编号数据，建立显示页面与编号数据的关联关系，并存储所述显示页码与编号数据的关联关系，以便后续调用。
步骤S106，若接收到刷新指令，则根据所述显示页码与所述编号数据的关联关系对当前页面显示的目标数据流进行分页刷新。
在本实施例中，步骤S106具体包括：
若接收到刷新指令，则读取当前页面的显示页码，根据所述显示页码及所述显示页码与所述编号数据的关联关系获取所述当前页面显示的目标数据流的编号；
根据所述当前页面显示的目标数据流的编号数据请求读取对应的汽车数据流，并利用读取的汽车数据流对所述当前页面显示的目标数据流进行刷新。
同样的，在接收到翻页指令后，根据翻页后的页码，选取对应显示的目标数据流的编码数据，然后根据所述编码数据来读取相应的目标数据流。
在本实施例中，在为各类型汽车数据流编号时，汽车诊断设备会记录汽车数据流类型与编号数据之间的对应关系，所述根据所述当前页面显示的目标数据流的编号数据请求对应的汽车数据流具体包括：根据所述当前页面显示的目标数据流的编号数据确定需要重新采集的汽车数据流类型；然后根据所述需要重新采集的汽车数据流类型采集相应的汽车数据流。
在本实施例中，由于在当前页面下接收到刷新指令时，仅重新获取当前页面显示的目标数据流，而无需重新获取所有目标数据流，因此可以减少数据获取所需时间，提高刷新速度。
优选的，在本实施例中，在所述若接收到刷新指令之后还包括：
判断当前是否处于汽车数据流录制状态；
若处于非录制状态，则进入根据所述显示页码与所述编号数据的关联关系对当前页面显示的目标数据流进行分页刷新的步骤；
若处于录制状态，则选择全部页面所显示的目标数据流的编号数据，根据所述全部页面所显示的目标数据流的编号数据进行页面刷新。
由于汽车诊断设备在录制状态下，需要将全部目标数据流保持到录制数据流文件下，因此若在录制状态下接收到刷新指令，则需要同时对所有目标数据流进行刷新。
以上可以看出，本实施例提供的汽车数据流显示方法由于对无序显示的至少一条汽车数据流进行排序后显示，从而可以方便诊断人员快速从众多汽车数据流中查找出目标数据流；由于对目标数据流进行分页刷新，从而可以提高查看目标数据流时数据流的刷新速度。
图2是本申请一具体实现示例提供的汽车数据流显示方法的实现流程示意图，该方法应用于汽车诊断设备。参见图2所示，该方法的具体实现流程详述如下：
步骤S201，对无序显示的100条汽车数据流进行编号。按照100条汽车数据流的位置，将其分别编号为0~99。
步骤S202，按照数据流标题的字母升序或降序对这100条汽车数据流进行排序，并按照排序顺序显示这100条汽车数据流。假设，按数据流标题的字母升序或降序排列后的顺序为：第1条，第11条，第21条，第31条，...第91，第2条，第12条，...第92条；第3条，第13条，... 第92条；...第10条，第20条，...第100条。
步骤S203，假设将这100条汽车数据流全部选择作为目标数据流，那么按照数据流标题的排序顺序对这100条汽车数据流进行分10页进行显示，每页显示10条汽车数据流。其中：
第1页汽车数据流显示的位置编号为：0,10,20,30，...90；
第2页汽车数据流显示的位置编号为：1,11,21,31，...91；
 ...
第10页汽车数据流显示的位置编号为：9,19,29,39，...99。
步骤S204，对数据流编号进行简化，用100个位置，“1”表示需要刷新的数据，“0”表示不需要刷新的数据。即：
第1页需要刷新数据为（位置编号为0,10,20,30，..90的值为1，其他位为0）：1000000000100000000010000000001000000000100000000010000000001000
000000100000000010000000001000000000；
第2页需要刷新数据为（位置编号为1,11,21,31，..91的值为1，其他位为0）：0100000000010000000001000000000100000000010000000001000000000100
000000010000000001000000000100000000；
...
第10页需要刷新数据为（位置编号为9,19,29,39，..99的值为1，其他位为0）：0000000001000000000100000000010000000001000000000100000000010000
000001000000000100000000010000000001。
步骤S205，对每页的数据流编号每8个位置为一个整体，最后不足8为的用0补齐，转换成16进制的数据。例如：
第1页的10000000 00100000 00001000 00000010 00000000 10000000 00100000 00001000 00000010 00000000 10000000 00100000 00000000（后面4个0为补齐数据）转化成0x80,0x20,0x08,0x02,0x00, 0x80,0x20,0x08,0x02,0x00, 0x80,0x20, 0x00；
第2页的01000000 00010000 00000100 00000001 00000000 01000000 00010000 00000100 00000001 00000000 01000000 00010000 00000000（后面4个0为补齐数据）转化成0x40,0x10,0x04,0x01,0x00, 0x40,0x10,0x04,0x01,0x00, 0x40,0x10, 0x00；
....
第10页的
00000000 01000000 00010000 00000100 00000001 00000000 01000000 00010000 00000100 00000001 00000000 01000000 00010000（后面4个0为补齐数据）转化成0x00,0x40,0x10,0x04,0x01, 0x00,0x40,0x10,0x04,0x01, 0x00,0x40,0x10。
步骤S206，当不是录制状态时，根据要显示的页码，将对应页码下的数据流编码数据，通过诊断设备去读取汽车的汽车数据流数据，对得到的诊断设备读取到的汽车数据流进行排序后进行显示。翻页时，改变页码，更改向数据流编码数据。诊断设备通过数据流编码数据，请求对应页需要请求的数据流。
以上可以看出，本实施例提供的汽车数据流显示方法同样由于对汽车数据流进行排序后显示，从而可以方便诊断人员快速从众多汽车数据流中查找出目标数据流；由于对目标数据流进行分页刷新，从而可以提高查看目标数据流时数据流的刷新速度。
