具体实施方式
为了便于理解本发明,下面结合附图和具体实施例,对本发明进行更详细的说明。需要说明的是,当元件被表述“固定于”另一个元件,它可以直接在另一个元件上、或者其间可以存在一个或多个居中的元件。当一个元件被表述“连接”另一个元件,它可以是直接连接到另一个元件、或者其间可以存在一个或多个居中的元件。本说明书所使用的术语“上”、“下”、“内”、“外”、“底部”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。此外,术语“第一”、“第二”“第三”等仅用于描述目的,而不能理解为指示或暗示 相对重要性。
除非另有定义,本说明书所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本说明书中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的,不是用于限制本发明。本说明书所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
此外,下面所描述的本发明不同实施例中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
对于使用者或者厂商而言,了解车辆的实际运行状况或者明确异常情况发生的原因主要依赖于车辆内部或者外接的车辆诊断设备。车辆诊断设备可根据时间先后顺序,以特定的数据格式记录形成的一系列车辆诊断数据,但是,这些车辆诊断数据一方面直接记录或者保存在车辆诊断设备,在没有专业设备的前提下,很难被读取或者获得。另一方面,其数据格式与一般的模式不相同,没有专业的基础知识或者解析编译设备的话,其具体代表的含义或者意义很难被用户所理解。
本发明实施例提供的车辆诊断数据显示方法应用在车辆诊断数据显示系统时,可以帮助提高车辆的使用体验和交互友好程度。图1为本发明实施例提供的,应用该车辆诊断数据显示方法的车辆诊断数据显示系统示意图。
如图1所示,所述车辆诊断数据显示系统可以包括车辆诊断设备10以及与车辆诊断设备10通信连接的移动终端20。
其中,该车辆诊断设备10可以是能准确査明车辆、总成和机构的技术状况,并得出诊断数据的不解体检验测试机械设备。主要有车轮平衡器、灯光检验仪、反力式制动试验台、底盘测功机、侧滑试验台、前轮定位仪、发动机试验台、废气分析仪、排气烟度计、轮胎/刹车片检测仪、TPMS胎压监测仪、ADAS辅助驾驶检测仪、四轮定位检测仪和噪声计等。
移动终端20与车辆诊断设备10通信连接,用于获取以及显示车辆诊断设备对车辆进行诊断得到的车辆诊断数据。在本发明的一实施例中,移动终端20可以是手机、平板电脑和遥控器中的至少一种。
图2为本发明实施例提供的车辆诊断设备10的功能框图。如图2所示,该车辆诊断设备10内部至少可以搭载有如下的设备模组:存储器11以及处理 器12。
其中,所述存储器11具体可以采用任何类型的非易性存储设备,例如,SRAM等,具有满足使用需要的存储空间以存储数据信息和/或程序指令。所述存储器11上设置有至少一个存储分区,用于存储车辆诊断数据。
该车辆诊断数据是指在车辆运行过程中记录得到的,或者在车辆处于停止状态时,对车辆进行诊断获得的,表示车辆各个部件和模组工作状态的相关数据,例如驱动电机的电流和输出功率,车辆轮胎的胎压等。车辆诊断数据通常以硬件设备直接检测获得的数据信号而记载,更偏向于机器硬件的应用而对正常人的理解非常不友好,难以被解读。
在一些实施例中,该车辆诊断数据可以体现在以时间为横坐标延伸的行驶曲线上。每一时刻的车辆诊断数据属于行驶曲线对应时刻的特征点。
所述处理器12是整个车辆诊断设备10的控制核心,包括用于接收控制指令调整车辆诊断设备10的诊断时刻、诊断数据。其具体可以采用任何类型的中央处理器、微控制器或者类似的逻辑处理芯片。
所述处理器12与所述存储器11之间通信连接,可以实现双向数据传输。以该通信连接为基础,所述处理器12通过调用存储在存储器内的计算机程序指令以完成飞行器控制系统的全部功能,并且将车辆行驶过程中或者车辆处于停止状态时进行诊断得到的车辆诊断数据记录在存储器相应的存储区内。
请继续参阅图1,移动终端20是位于使用者一侧,实现车辆诊断设备10与使用者之间交互行为的终端设备。
为实现上述的交互行为,该移动终端20可以设置有一个或者多个输入/输出设备,例如显示屏、按键、触控屏幕、扬声器或者摇杆等,分别用于采集用户指令并向用户反馈相关信息。该移动终端可以为特地研发的基于Android的Ultra设备。
移动终端20与车辆诊断设备10之间具体可以通过无线收发模块30来实现与对方的无线通信连接,以此实现遥控器20与车辆诊断设备10之间的双向数据传输。
在一些实施例中,移动终端20可以是针对车辆诊断设备10特别设置的专属遥控器,与车辆诊断设备10之间相互配合使用。
在另一些实施例中,该移动终端20还可以是运行有车辆诊断设备的供应 商或者服务供应商为车辆诊断设备额外提供的移动应用40的智能终端设备,包括但不限于智能手机、平板电脑、手提电脑、个人可穿戴式设备等。
一个或者多个用户可以通过自己的智能终端设备运行该移动应用40,绑定或者注册一个或者多个车辆诊断设备10,并且通过移动应用40提供的交互界面,向已经绑定或者注册车辆诊断设备10发送一个或者多个指令或者接收车辆诊断设备10返回的数据信息,担任移动终端20的角色。
在一些实施例中,当确定车辆诊断设备处于开启状态时,用户可以通过移动终端20的输入设备(如触摸屏、按键或者摇杆)输入特定的触发指令,向车辆诊断设备发送车辆诊断数据列表获取指令。
在车辆诊断设备10接收到移动终端20发送的车辆诊断数据列表获取指令时,车辆诊断设备10根据接收到的指令将车辆诊断数据列表发送至移动终端20。
移动终端20在接收到车辆诊断设备发送的车辆诊断数据列表之后,将车辆诊断数据列表进行展示,具体展示方式可包括以时间列表等形式,展示车辆诊断设备内存储的车辆诊断数据。使用者据此可以简单的通过勾选等方式,在移动终端上选择自己感兴趣的车辆诊断数据。
例如,用户在移动终端20上输入相应的选择指令(例如点击查看或者下载某个时间节点的车辆诊断数据),选中自己感兴趣的车辆诊断数据。
处理器12在确定了用户选中的车辆诊断数据以后,调用相应的计算机程序指令来执行数据发送的步骤,将车辆诊断数据发送至移动终端。其中,车辆诊断数据最终可以通过无线收发模块30反馈至移动终端20内。
在一些实施例中,移动终端20将车辆诊断数据转换为可被用户理解的数据并进行显示。
具体的,基于移动终端20所具备的输出设备,其可以将这些车辆诊断数据转换为可被用户理解的数据并且向用户显示。例如,通过显示屏以表格形式和图形格式的可被用户理解的数据来展示这些车辆诊断数据的内容。
在此,以“可被用户理解的数据”这样的术语来表示交互友好程度高,便于使用者理解的内容展示形式。在本实施例中仅以表格格式和图形图标格式为例进行描述。但本领域技术人员还可以根据实际情况的需要,选择使用其它任何类型的,具有便于使用者理解,简单易懂,交互体验良好等特点的数据形式。
本发明实施例提供的车辆诊断数据显示系统可以方便的令使用者可以根据自身的需求选取一个或者多个车辆诊断数据,并且将所述车辆诊断原始数据进行格式转换,获得格式转换后的当前车辆诊断数据;进一步将所述当前车辆诊断数据进行绘制,获得可被用户理解的当前车辆诊断数据;并在所述移动终端上显示所述可被用户理解的当前车辆诊断数据,简单便捷的向用户呈现车辆诊断数据,以便用户直观地获知车辆的运行状态,用户可以很容易的了解或者知晓车辆的运行情况或者导致出现异常情况的原因,进而及时的对车辆进行维护或者上报故障等,有利于提高车辆使用的可靠性,具有良好的用户使用体验。
图3为本发明实施例提供的,应用于上述车辆诊断数据显示方法。该显示方法由上述的移动终端所执行。如图3所示,该显示方法可以包括如下步骤:
310、确定并获取用户选中的车辆诊断原始数据。
在本实施例中,用户可通过点击、触摸、语音等方式在移动终端上输入相应的选择指令,例如点击查看或者下载某个时间节点的车辆诊断数据,选中自己感兴趣的车辆诊断数据。移动终端在接收到用户输入的选择指令之后,进行确定,并将确定的指令发送至车辆诊断设备,车辆诊断设备根据确定的指令将用户选中的车辆诊断原始数据发送至移动终端,移动终端接收车辆诊断设备发送的车辆诊断原始数据,其中,车辆诊断原始数据是指车辆诊断设备直接进行记录,没有经过移动终端进行格式转换以及绘制等操作的原始数据。
320、将所述车辆诊断原始数据进行格式转换,获得格式转换后的当前车辆诊断数据。
在获得车辆诊断原始数据之后,移动终端对车辆诊断原始数据进行格式转换,从而获得格式转换后的当前车辆诊断数据。具体地,对车辆诊断原始数据的格式转换,具体可根据车辆诊断原始数据的数据格式,获取对应的转换方式,从而进行格式转换。
即步骤320可具体包括:
A1,根据所述车辆诊断原始数据的数据类型,获取对应的数据转换方式;
A2,根据所述数据转换方式对所述车辆诊断原始数据进行格式转换,获得格式转换后的当前车辆诊断数据。
根据本实施例的方案,在对数据进行处理时,是基于数据类型的不同,进 行相应的转换后,从而便于对车辆诊断数据进行绘制。具体实施过程中,可设置转换格式的规则为将其他类型的数据,比如,整型,字节型等类型的数据。统一转换为浮点型数据。因此,在具体实施过程中,首先获取车辆诊断原始数据的数据类型,若车辆诊断原始数据的数据类型为浮点型,则不需要进行格式转换。若车辆诊断原始数据的数据类型为字节型,则获取将字节型数据转换为浮点型数据的转换方式,根据数据转换方式对车辆诊断原始数据进行格式转换,获得格式转换后的当前车辆诊断数据。
为了提高格式转换的效率,本发明实施例中,采用根据车辆诊断原始数据的数据类型的不同,可以设定不同的转换方式。
330、将所述当前车辆诊断数据进行绘制,获得可被用户理解的当前车辆诊断数据。
在获得当前车辆诊断数据之后,即可将当前车辆诊断数据进行绘制,从而将当前车辆诊断数据转化为可被用户理解的数据。具体可被用户理解的数据可以是以合适的数据格式,比如表格形式或者图形形式,或者表格形式与图形形式的组合,以便用户直观地获知并理解当前车辆诊断数据,从而能够直观地获知车辆状况。
当可被用户理解的当前车辆诊断数据的数据格式包含图形形式时,步骤330可包括:
B1,获取所述当前车辆诊断数据中的起始时间和终止时间;
B2,获取所述移动终端的屏幕尺寸与屏幕分辨率;
B3,根据所述屏幕尺寸与屏幕分辨率选取对应的坐标起始点;
B4,根据所述当前车辆诊断数据中的起始时间、终止时间以及所述屏幕分辨率选取对应的X轴坐标参数;
B5,根据所述当前车辆诊断数据中的数据大小选取对应的Y轴坐标参数;
B6,根据所述坐标起始点、X轴坐标参数以及Y轴坐标参数将所述当前车辆诊断数据进行绘制,获得所述当前车辆诊断数据的数据图形。
具体地,当可被用户理解的当前车辆诊断数据的数据格式包含图形形式时,比如波形图,首先获取当前车辆诊断数据中的起始时间,以及移动终端的屏幕尺寸与屏幕分辨率,并根据移动终端的屏幕尺寸与屏幕分辨率确定绘制当 前车辆诊断数据图形的坐标起始点。一般情况下,为了最大化显示图形,可将坐标起始点确定在屏幕的左下角,因此,在确定移动终端的屏幕尺寸与屏幕分辨率之后,可根据移动终端的屏幕尺寸与屏幕分辨率确定屏幕最左端的坐标,并将确定的坐标作为绘制当前车辆诊断数据图形的坐标起始点。
然后根据当前车辆诊断数据中的起始时间、终止时间以及屏幕分辨率选取对应的X轴坐标参数,其中X轴坐标参数包括X轴的起始距离、终止距离以及具体X轴代表的参数,比如时间等,其中,起始距离可根据当前车辆诊断数据中的起始时间确定,终止距离可根据当前车辆诊断数据中的终止时间确定,。并根据当前车辆诊断数据中的数据大小选取对应的Y轴坐标参数,其中,Y轴坐标参数包括Y轴距离以及具体Y轴代表的参数,比如胎压等,Y轴距离具体可根据当前车辆诊断数据的大小进行设置。
根据坐标起始点、X轴坐标参数以及Y轴坐标参数将当前车辆诊断数据进行绘制,具体绘制过程可包括将当前车辆诊断数据,对应添加至建立的坐标轴中,从而获得当前车辆诊断数据的数据图形。同时,为了区分每个时间点的车辆诊断数据的不同,可预先创建颜色池,分配给当前建立的图形展示区域中,每个时间点的车辆诊断数据不同的颜色,从而确保车辆诊断数据的展示区域能够更加直观清晰。
进一步地,在绘制当前车辆诊断数据的图形之后,可进一步提供图形缩放功能,即步骤B6之后还包括:
B7,根据所述当前车辆诊断数据中的起始时间与终止时间计算当前车辆诊断数据的第一时间间隔值;
B8,若所述第一时间间隔值小于预设值,则显示缩放提示;
B9,在接收到用户输入的放大指令时,根据所述放大指令中的放大倍数对所述当前车辆诊断数据的数据图形进行放大。
具体实施过程中,有时会存在一组车辆诊断数据的起始时间间隔很近甚至小于1个像素点的情况,此时在界面上即使绘制出来,使用者也无法查看该数据与对应波形,因此可提供缩放功能,可将展示区域细微的数据,放大后更加直观的去分析。
具体地,根据当前车辆诊断数据中的起始时间与终止时间计算当前车辆诊 断数据的第一时间间隔值,若第一时间间隔值小于预设值,则显示缩放提示,以供用户输入缩小或者放大指令,并在接收到用户输入的放大指令时,根据放大指令中的放大倍数对当前车辆诊断数据的数据图形进行放大,从而对图形进行放大,便于用户观察和分析。其中,预设值可为1秒,放大指令可包括用户通过双击移动终端屏幕、语音输入,用户手指在移动终端屏幕移动等方式触发。
340、在所述移动终端上显示所述可被用户理解的当前车辆诊断数据。
这些可被用户理解的数据由移动终端所具备的输出设备(扬声器和显示屏)进行显示,例如扬声器和显示屏。
进一步地,在显示被用户理解的当前车辆诊断数据之后,可进一步包括:
C1,获取下一条格式转换后的车辆诊断数据的起始时间;
C2,将所述下一条格式转换后的车辆诊断数据的起始时间,与所述当前车辆诊断数据的起始时间进行对比,获得第二时间间隔值;
若C3,若所述第二时间间隔值大于或等于预设值,则绘制所述下一条格式转换后的车辆诊断数据的图形,否则,舍弃所述下一条格式转换后的车辆诊断数据。
在具体实施过程中,通过车辆诊断设备产出的数据多则达到十几万条,如果将每条数据均绘制出来的会导致界面异常卡顿,不利于图形分析,因此。在完成当前车辆诊断数据的绘制之后,继续对下一条格式转换后的车辆诊断数据的起始时间进行遍历,将下一条格式转换后的车辆诊断数据的起始时间,与所述当前车辆诊断数据的起始时间进行对比,获得第二时间间隔值;当第二时间间隔值大于或等于预设值时,则绘制下一条格式转换后的车辆诊断数据,否则,舍弃下一条格式转换后的车辆诊断数据,其中,预设值可以为1s。从而减少间隔时间较短的车辆诊断数据的绘制,避免造成界面异常卡顿。
图4为本发明另一实施例提供的车辆诊断数据显示方法,该显示方法由移动终端与车辆诊断设备执行。如图4所示,该车辆诊断数据显示方法可以包括如下步骤:
410、在所述移动终端上显示所述车辆诊断设备内存储的车辆诊断数据。
420、所述移动终端用于确定用户选中的车辆诊断原始数据,并将确定指令发送至车辆诊断设备。
在移动终端显示车辆诊断设备内存储的车辆诊断数据,具体展示方式可包括以时间列表等形式,展示车辆诊断设备内存储的车辆诊断数据。用户可通过点击、触摸、语音等方式在移动终端上输入相应的选择指令,例如点击查看或者下载某个时间节点的车辆诊断数据,选中自己感兴趣的车辆诊断数据。移动终端在接收到用户输入的选择指令之后,进行确定,并将确定指令发送至车辆诊断设备。其中,车辆诊断原始数据是指车辆诊断设备直接进行记录,没有经过移动终端进行格式转换以及绘制等操作的原始数据。
430、所述车辆诊断设备用于根据所述确定指令将用户选中的车辆诊断原始数据发送至所述移动终端。
车辆诊断设备在接收到确定指令之后,根据确定指令将用户选中的车辆诊断原始数据发送至所述移动终端。
440、所述移动终端接收所述车辆诊断原始数据,并根据所述车辆诊断原始数据的数据类型,获取对应的数据转换方式,根据所述数据转换方式对所述车辆诊断原始数据进行格式转换,获得格式转换后的当前车辆诊断数据。
在接收到车辆诊断原始数据之后,对车辆诊断原始数据进行数据处理,在对数据进行处理时,是基于数据类型的不同,进行相应的转换后,从而便于对车辆诊断数据进行绘制。具体实施过程中,可设置转换格式的规则为将其他类型的数据,比如,整型,字节型等类型的数据。统一转换为浮点型数据。因此,在具体实施过程中,首先获取车辆诊断原始数据的数据类型,若车辆诊断原始数据的数据类型为浮点型,则不需要进行格式转换。若车辆诊断原始数据的数据类型为字节型,则获取将字节型数据转换为浮点型数据的转换方式,根据数据转换方式对车辆诊断原始数据进行格式转换,获得格式转换后的当前车辆诊断数据。
为了提高格式转换的效率,本发明实施例中,采用根据车辆诊断原始数据的数据类型的不同,可以设定不同的转换方式。
450、所述移动终端将所述当前车辆诊断数据进行绘制,获得可被用户理解的当前车辆诊断数据。
在获得当前车辆诊断数据之后,即可将当前车辆诊断数据进行绘制,从而将当前车辆诊断数据转化为可被用户理解的数据。具体可被用户理解的数据可 以是以合适的数据格式,比如表格形式或者图形形式,或者表格形式与图形形式的组合,以便用户直观地获知并理解当前车辆诊断数据,从而能够直观地获知车辆状况。
460、在所述移动终端上显示所述可被用户理解的当前车辆诊断数据。

在具体实施过程中,通过车辆诊断设备产出的数据多则达到十几万条,如果将每条数据均绘制出来的会导致界面异常卡顿,不利于图形分析,因此。在完成当前车辆诊断数据的绘制之后,继续对下一条格式转换后的车辆诊断数据的起始时间进行遍历,将下一条格式转换后的车辆诊断数据的起始时间,与所述当前车辆诊断数据的起始时间进行对比,获得第二时间间隔值;当第二时间间隔值大于或等于预设值时,则绘制下一条格式转换后的车辆诊断数据,否则,舍弃下一条格式转换后的车辆诊断数据,其中,预设值可以为1s。从而减少间隔时间较短的车辆诊断数据的绘制,避免造成界面异常卡顿。
