在一些实施例中，所述第一收容腔104和所述第二收容腔105呈预定角度设置，来达到放置于所述第一收容腔104内的光电组件201发射出的光束的中心轴和放置于所述第二收容腔105内的图像采集组件202的光轴更好的呈预设夹角设置。所述图像采集组件202的光轴与所述光电组件201发射的光束的中心轴呈预设角度，以使图像采集组件202可以更好的采集光电组件201发射并且打到所述刹车盘或所述踏面的光线形成的图像。
为了方便用户理解本发明的发明构思，以下以轮胎举例说明检测设备的检测过程。
如图6所示，将所述磨损诊断系统1的支撑座103抵接轮胎2的表面，然后通过启动按键106启动所述磨损诊断系统1，所述控制单元50控制所述光电组件201向所述轮胎2发射光束，所述图像采集装置30采集所述光电组件201发射至所述轮胎2上的图像，并将采集到的图像传输至所述控制单元50，所述控制单元50根据所述图像采集组件202传输过来的图像进行运算处理并得出所述轮胎2的磨损状态。
在一些实施例中，在光电组件201放置于所述第一收容腔104内时，所述光电组件201发射的光束中心轴与所述支撑座103呈直角。
在一些实施例中，为了提升检测效果，所述光电组件201发射出的光束投影至所述刹车盘或所述踏面形成的直线与所述刹车盘或所述踏面的中心轴平行。
请参阅图7，由于轮胎2具有不同的尺寸，不同的轮胎2由于尺寸的不同，附着于所述轮胎2上的编码信息的区域大小也不尽相同，因此所述编码读取单元30在识别所述轮胎2的编码信息时所述磨损诊断系统1距离所述轮胎2的距离也各不相同，所述变焦镜头可以通过变焦实现对所述轮胎编码信息的对焦。当所述编码读取单元30将对焦后的轮胎信息图像传递至所述控制单元50，所述控制单元50将对所述编码信息图像进行解析从而获取所述轮胎2的相应信息，例如：胎面宽度、扁平比、子午线、使用轮毂尺寸、载重指数、速度以及轮胎的DOT信息(生产商、生产厂信息、耐磨指数、牵引力指数、耐高温指数、承重质量和胎面磨损指数等)，然后所述控制单元50将所述轮胎2的相应 信息传输至所述显示单元60以供用户查看，同时所述控制单元50将所述轮胎信息进行存储，待所述磨损诊断系统1对所述刹车盘或所述踏面进行检测后结合所述轮胎2的信息进行计算分析得到精确的轮胎磨损状况，从而判断所述刹车盘或所述轮胎2是否需要更换，并将所述轮胎磨损状况及判断信息传输至所述显示单元60以供用户查看。
对于上述反馈单元40，所述反馈单元40设置于所述手持外壳10内，所述反馈单元40电性连接所述控制单元50。当所述控制单元50将所述图像采集组件202传输过来的图像进行运算处理完毕后，所述控制单元50将控制所述反馈单元40输出提示消息。
具体的，所述反馈单元40包括震动马达(图未示)和蜂鸣器(图未示)，所述震动马达和所述蜂鸣器均电性连接所述控制单元50。其中所述震动马达通过发生震动和所述蜂鸣器发出蜂鸣从而提示用户进行不同的操作步骤，例如：所述震动马达震动代表所述磨损诊断系统1与所述刹车盘或所述踏面的接触面接触不良，需要重新调整所述支撑座103与所述刹车盘或所述踏面的接触位置，所述蜂鸣器发出蜂鸣代表检测未完成但是所述支撑座103却与所述刹车盘或所述踏面脱离。
所述磨损诊断系统1还包括显示单元60，所述显示单元60电性连接所述控制单元50和所述编码读取单元30。所述显示单元60和所述光电组件201相对设置于所述手持外壳10的两侧，即：所述显示单元60设置于所述手持外壳10的一侧，所述光电组件201和所述图像采集组件202设置于所述手持外壳10的另一侧。
在本发明实施例中，所述显示单元60设置于所述壳体背向所述第一收容腔104和所述第二收容腔105的一侧，所述编码读取单元30和所述光电组件201以及所述图像采集组件202处于同一侧。所述控制单元50在完成来自图像采集组件202的图像运算处理或对来自所述编码采集单元的轮胎编码信息图像进行解析后控制所述反馈单元40进行提示，同时结合解析后的轮胎编码信息将将所述刹车盘或所述踏面的检测分析结果显示在所述显示单元60上，例如：踏面或刹车盘磨损程度，剩余安全行驶公里数等。或所述显示单元60显示轮胎信息，例如：胎面宽度、扁平比、子午线、使用轮毂尺寸、载重指数、速度以及轮胎的DOT信息(生产商、生产厂信息、耐磨指数、牵引力指数、耐高温指数、承重质量和胎面磨损指数等)。或所述显示单元60用于实时显示所述编码读取单元30拍摄的视频数据。值得说明的是，所述显示单元60和所述启动按键106设置于所述手持外壳10的同一侧。
在一些实施例中，所述显示单元60还包括为触控显示单元60(未标示)，用户也可通过所述触控显示单元60对所述磨损诊断系统1进行操作，然后通过所述显示单元60查看所述刹车盘或所述踏面不同的参数，或者，通过所述显示单元60查看所述轮胎的信息。
在一些实施例中，所述磨损诊断系统1还包括输入单元61，所述输入单 元61与所述控制单元50电性连接，用于接收用户输入的指令，所述指令用于指示所述控制单元50控制所述编码读取单元30从所述视频数据中采集所述编码的图像。当用户通过所述显示单元60实时查看所述编码读取单元30提供的视频数据后，用户由于图像信息磨损或者无法理解图像信息，则对所述输入单元61输入指令，所述输入单元61根据所述指令指示所述控制单元50对所述编码读取单元30获取的图像进行解析或许轮胎数据，然后所述控制单元50将解析后的轮胎数据按照预定格式传输至所述显示单元60，由显示单元60显示解析后的轮胎数据供用户查看。
在一些实施例中，所述磨损诊断系统1还包括供电单元90，所述供电单元90设置于所述手持外壳10内，所述供电单元90分别连接所述光电组件201、图像采集组件202、控制单元50和反馈单元40。
在另一些实施例中，所述磨损诊断系统1可以没有供电单元90，所述磨损诊断系统1通过外接电源给所述光电组件201、图像采集组件202、控制单元50和反馈单元40供电。
本发明实施例中，通过将检测单元20和编码读取单元30设置于手持外壳10中，通过检测单元20可快速对刹车盘或踏面进行检测，通过编码读取单元可快速识别轮胎信息，所述磨损诊断系统1结合所述轮胎信息进行刹车盘或踏面的状态进行判断，并将所述刹车盘或踏面的状态信息和判断结果通过显示单元向用户展示。
综上，通过上述磨损诊断系统可以获取刹车盘或轮胎踏面的磨损测量数据，根据磨损测量数据判断刹车盘或轮胎的磨损状态。
其中，需要说明的是，刹车盘或轮胎踏面的磨损测量数据不仅可以根据上述实施例中的磨损诊断系统，采用激光测量方法获取磨损测量数据，还可以通过其他测量方法获取刹车盘或轮胎踏面的磨损测量数据，例如：卡尺测量等测量方法。根据刹车盘或轮胎踏面磨损测量数据和刹车盘或轮胎踏面的磨损更换标准，可以判别该刹车盘或轮胎是否需要更换，生成对应的磨损诊断结果。
基于上述系统，下面以刹车盘磨损诊断方法为例，详细介绍磨损诊断方法的步骤和工作过程。
请参阅图图8，图8是本发明实施例提供的一种刹车盘磨损诊断方法，该刹车盘磨损诊断方法应用于任意类型的磨损诊断系统，如图8所示，该刹车盘磨损诊断方法S20包括：
S21、获取特征信息，所述特征信息用于表征所述刹车盘的特征或所述刹车盘所属汽车的特征；
S22、根据所述特征信息，获取所述刹车盘的磨损更换标准；
S23、获取所述刹车盘的磨损测量数据；
S24、根据所述磨损测量数据和所述刹车盘的磨损更换标准，生成磨损诊断结果。
特征信息可以包括一个或多个特征，该特征为刹车盘的特征或者刹车盘所 属汽车的特征，若获取的是刹车盘的特征信息，其特征可以为刹车盘的尺寸、配置等特征中的至少一个，刹车盘的配置可以包括刹车盘的厚度、安装孔、螺栓孔数、螺栓孔径、使用材料等参数。若获取的是刹车盘所属汽车的特征，可以获取所属汽车的VIN码，即车辆识别号码(Vehicle Identification Number,或车架号码)，简称VIN，是一组由十七个字母或数字组成，用于汽车上的一组独一无二的号码，可以识别汽车的生产商、引擎、底盘序号及其他性能等资料。在一些实施例中，根据汽车VIN码获取刹车盘的特征信息，具体是根据VIN码和预设的汽车和刹车盘的特征信息对应关系，获取刹车盘的特征信息，预设的汽车和刹车盘的特征信息对应关系可以由用户根据需要而设置，根据VIN码即可以在预设的对应关系中查找该VIN码对应的刹车盘的特征信息，再根据刹车盘的特征信息，获取对应的刹车盘的磨损更换标准。在一些实施例中，根据汽车的VIN码，还可以直接获取汽车的特征信息，汽车的特征可以为汽车的车型、车款、出厂年份以及常规选装件代码列表中的至少一个，其中，常规选装件代码列表中包含有汽车的各个零件的型号、颜色、装卸方式或者汽车所使用的某个系统等，例如：汽车座椅材料和颜色等、汽车车型、汽车空气湿度和挡风玻璃温度传感器设备、座椅系统、电动滑动天窗、生产厂家代码等汽车的特征信息，再根据汽车的特征信息，获取对应的刹车盘的磨损更换标准。
获取刹车盘的特征信息或者刹车盘所属汽车的特征信息以后，再根据该特征信息，获取刹车盘的磨损更换标准，磨损更换标准用于指示刹车盘磨损到什么程度，可以进行更换。特征信息与刹车盘的磨损更换标准可以预先进行关联或者映射，根据某个特征信息，可以精准查找对应的刹车盘的磨损更换标准，再将刹车盘的磨损测量数据和刹车盘的磨损更换标准进行对应，判断刹车盘的磨损测量数据是否达到了刹车盘的磨损更换标准，生成对应的磨损诊断结果。在一些实施例中，若所述磨损测量数据达到所述刹车盘的磨损更换标准，生成第一磨损诊断结果，用于表征所述刹车盘需要更换，并生成提示信息，提示用户及时更换刹车盘，以防发生事故，若磨损测量数据未达到刹车盘的磨损更换标准，生成第二磨损诊断结果，用于表征所述刹车盘不需要更换，用户可以继续使用。因此，用户可以根据诊断结果，及时对刹车盘的磨损做出相应处理，以防事故的发生。
综上所述，该刹车盘磨损诊断方法可以根据特征信息，精确获取刹车盘的磨损更换标准，精准查找刹车盘的磨损更换标准，最后根据磨损测量数据和刹车盘的磨损更换标准，生成磨损诊断结果，相对于通过维修手册手动查找刹车盘的磨损更换标准，可以大大提高查找效率，以及查找更加精准，进而提升用户体验。
在一些实施例中，获取刹车盘的特征信息可以通过多种方式进行获取，可以直接获取也可以间接获取。获取刹车盘的特征信息时可以接收用户输入的所述刹车盘的特征信息；或者，通过上述磨损诊断系统在获取磨损测量数据时获取，具体地，用户将上述磨损诊断系统放于刹车盘上，按下按键，磨损诊断系 统发射激光至刹车盘表面，开始进行磨损测量，同时获取刹车盘的特征信息或者刹车盘所属汽车的特征信息；或者，通过上述磨损诊断系统中的相机获取所述刹车盘的部分或全部图像，根据所述刹车盘的部分或全部图像，解析出所述刹车盘的特征信息，可以通过相机对刹车盘进行拍照，获取刹车盘的部分或全部图像，再通过一些图像分析算法对刹车盘的部分或全部图像进行相应处理和分析，解析出刹车盘的特征信息，例如：根据刹车盘的部分或全部图像，获得刹车盘的尺寸、孔径大小以及材质等特征信息。
特征信息和刹车盘的磨损更换标准可以共同构成磨损信息表，磨损信息表中可以包含刹车盘的特征、刹车盘所属汽车的特征以及对应的刹车盘的磨损更换标准等多个信息。具体地，请参阅图9，步骤S22包括：
S221、获取第一磨损信息表，所述第一磨损信息表包括所述刹车盘的特征信息与所述刹车盘的磨损更换标准的对应关系；
S222、根据所述刹车盘的特征信息，从所述第一磨损信息表中查找并获取所述刹车盘的特征信息对应的所述刹车盘的磨损更换标准。
第一磨损信息表可以根据刹车盘的特征信息与刹车盘的磨损更换标准预先制定，制定完成以后，存储于控制单元，该第一磨损信息表中包括刹车盘的特征信息与刹车盘的磨损更换标准的对应关系，可以是多个特征信息对应一个刹车盘的磨损更换标准，也可以是每个特征信息均对应一个刹车盘的磨损更换标准，还可以是多个特征信息对应同一个刹车盘的磨损更换标准。例如，请参阅表1，刹车盘的特征信息与刹车盘的磨损更换标准的对应关系如表1所示：
表1
Figure PCTCN2021117000-appb-000001
根据相应刹车盘的不同尺寸、材料或者配置等相关特征信息，可以查找获取到对应的磨损更换标准。第一磨损信息表的形式还可以如表2所示：
表2
Figure PCTCN2021117000-appb-000002
Figure PCTCN2021117000-appb-000003
即不同的特征信息可以对应同一个磨损更换标准，通过任意一个刹车盘特征，均可以获取对应的刹车盘的磨损更换标准。
再根据刹车盘的特征信息，从第一磨损信息表中查找并获取刹车盘的特征信息对应的刹车盘的磨损更换标准。例如：刹车盘的特征信息为尺寸1、材质1或者配置1，在第一模式信息表中就可以查找到上述特征信息对应的刹车盘的磨损更换标准为磨损标准1，进而获取该磨损标准1。
因此，通过特征信息，可以及时精确查找到该特征信息对应的刹车盘的磨损更换标准，大大提高查找效率，且查找更加精确。再根据刹车盘的磨损测量数据和该磨损更换标准，生成对应的磨损诊断结果，若达到磨损更换标准，可以及时通知用户对刹车盘进行更换，防止发生事故。
若获取特征信息时，是通过获取刹车盘所属汽车的VIN码，再根据VIN码获取汽车的特征信息，例如汽车车型、车款、出厂年份以及常规选装件代码列表等特征信息，则可以在第二磨损信息表中，根据特征信息，获取刹车盘的磨损更换标准，具体地，请参阅图10，步骤步骤S22还包括：
S223、获取第二磨损信息表，所述第二磨损信息表包括所述汽车的特征信息与所述刹车盘的磨损更换标准的对应关系；
S224、根据所述汽车的特征信息，从所述第二磨损信息表中查找并获取所述汽车的特征信息对应的所述刹车盘的磨损更换标准。
第二磨损信息表中包含汽车的特征信息，及其对应的刹车盘的磨损更换标准，第二磨损信息表的形式可以如同表1或表2所示，只是特征信息为汽车的特征信息，同样地，多个汽车的特征信息对应同一个刹车盘的磨损更换标准，可以是多个汽车特征信息对应一个刹车盘的磨损更换标准，也可以是每个汽车特征信息均对应一个刹车盘的磨损更换标准，还可以是多个汽车特征信息对应同一个刹车盘的磨损更换标准。
再根据汽车的特征信息，从第二磨损信息表中查找其对应的刹车盘的磨损更换标准，再获取该磨损更换标准，因此，通过汽车特征信息，可以及时精确查找到该特征信息对应的刹车盘的磨损更换标准，大大提高查找效率，且查找更加精确。再根据刹车盘的磨损测量数据和该磨损更换标准，生成对应的磨损诊断结果，若达到磨损更换标准，可以及时通知用户对刹车盘进行更换，防止发生事故。
汽车的特征可能会适配不同的轮胎，例如一些原装轮胎，或者后装轮胎，即使不同批次的出厂车辆的轮胎也可能不同，因此，汽车的特征信息与刹车盘的磨损更换标准的对应方式可能不如轮胎中刹车盘的特征和更换标准对应的那么紧密，可能会对应多个刹车盘的磨损更换标准。若与所述汽车的特征信息 对应的所述刹车盘的磨损更换标准的数量为至少两个，则确定与该汽车的特征信息对应的刹车盘的特征信息，根据刹车盘的特征信息从所述至少两个所述刹车盘的磨损更换标准中选取出一个所述刹车盘的磨损更换标准。刹车盘的特征信息与磨损更换标准的对应关系更加紧密，因此，在汽车的特征信息对应不同的刹车盘的磨损更换标准时，可以再根据该汽车的特征信息对应的刹车盘特征信息，查找对应的磨损更换标准，查找的刹车盘的磨损更换标准更加精确，进而能够根据刹车盘的磨损测量信息和磨损更换标准，更加精确地判定刹车盘是否需要更换或保养。
综上所述，该刹车盘磨损诊断方法可以根据特征信息，精准查找刹车盘的磨损更换标准，最后根据磨损测量数据和刹车盘的磨损更换标准，生成磨损诊断结果，相对于通过维修手册手动查找刹车盘的磨损更换标准，可以大大提高查找效率，以及查找更加精准，进而提升用户体验。
轮胎踏面磨损诊断方法与上述刹车盘磨损诊断方法的工作原理和过程均类似，均基于相同的发明构思，因此，上述刹车盘磨损诊断方法实施例中的相应内容同样适用于轮胎踏面磨损诊断方法实施例，此处不再详述。但是，在轮胎踏面磨损诊断方法中，获取轮胎踏面的特征信息时，获取的特征信息包括轮胎的胎面宽度、扁平比、子午线、使用轮毂尺寸、载重指数、速度以及所述轮胎的DOT信息中的至少一个，其中轮胎的DOT信息还包括生产商、生产厂信息、耐磨指数、牵引力指数、耐高温指数、承重质量和胎面磨损指数等信息。
综上所述，该刹车盘或者轮胎踏面磨损诊断方法可以根据特征信息，精准查找刹车盘或者轮胎踏面的磨损更换标准，最后根据磨损测量数据和刹车盘或者轮胎踏面的磨损更换标准，生成对应磨损诊断结果，相对于通过维修手册手动查找刹车盘或者轮胎踏面的磨损更换标准，可以大大提高查找效率，以及查找更加精准，进而提升用户体验。
