Description

一种用于跟踪车辆部件状态的状态跟踪系统
技术领域
本申请涉及一种用于跟踪车辆中的悬挂系统或转向系统中的部件的物理状况的状态跟踪系统。
背景技术
悬挂和各种转向部件，如车辆中的叉骨，随着时间的推移可能会变形并形成裂纹。这些部件的估计寿命是通过试验得出的；然而，由于各种影响，它们可能在估计的时间之前变形。用户可以在变形的后续阶段识别到变形，或者根本不会识别到变形。用户没有注意到的变形可能会导致部件损坏，以及严重的事故。
文献CN106080072描述了一种系统，其中借助于应力传感器测量这些部件的张力并且相应地进行故障检测。然而，它可能会导致不准确的损坏检测，因为在车辆运行的各种情况和条件下，即使部件没有变形，部件也可能受到过大的应力。
因此，上述所有问题使得有必要在相关技术领域进行创新。
发明内容
本发明涉及一种状态跟踪系统，以克服上述缺点并给相关技术领域带来新的优点。
本发明的一目的是提供一种状态跟踪系统，该系统能够即时跟踪车辆中的悬挂和转向部件。
本发明的另一目的是提供一种状态跟踪系统，该系统能够提高待检测部件的变形的准确率。
本发明是一种状态跟踪系统，用于跟踪车辆中的悬挂系统或转向系统中的部件的物理状况，以实现上面提到的并且将从以下详细描述中呈现的所有目的。因此，其新颖性包括与部件本体连接的传感器单元、被配置为以接收由上述传感器单元进行的测量结果作为输入的方式与传感器单元连接的处理器单元，并且所述处理器单元被配置为从其接收的测量结果中获得测量信息，通过根据存储器单元中的参考值对测量信息进行分类来生成状态信息，并且在用户界面上显示状态信息。因此，部件的状态被实时监控，并且异常情况被即时报告给用户。
本发明的一可能的实施例，其特征在于处理器单元被配置为计算并获得上述测量信息的测量值在预定范围内的变化。因此，防止了由环境因素组成的瞬时峰值测量导致不正确的状态信息。
本发明的另一可能的实施例的特征在于，所述传感器单元包括至少一个振动传感器。因此，可以确定部件中是否存在裂纹。
本发明的另一可能的实施例的特征在于，传感器单元包括声学传感器、温度传感器和电场传感器中的至少一个。因此，降低了由于环境因素引起对裂纹或损伤的不准确检测而导致测量值变化的可能性。
本发明的另一可能的实施例的特征在于，处理器单元被配置为考虑从车辆传感器单元接收的测量结果，该车辆传感器单元在生成状态信息的同时生成与车辆运动相关的信号。因此，在车辆在坡道上、快速转弯、高速行驶或在崎岖道路上行驶的情况下，防止从传感器单元获取的测量结果导致错误的损坏检测。
本发明的另一可能实施例的特征在于，在用户终端上设置上述用户接口，并且状态跟踪系统包括用于使处理器能够向用户接口发送数据的第一通信单元。
本发明的另一可能的实施例的特征在于，所述第一通信单元被配置为进行无线通信。
本发明的另一可能的实施例的特征在于，状态跟踪系统包括第二通信单元，以确保由上述处理器单元生成的状态信息和/或测量结果被发送到服务器。因此，可以在服务器上收集关于健康和损坏部件的信息，并通过即时状态服务器将其传输给其他用户或操作员。

附图说明

具体实施方式
在本申请的详细描述中，不具有任何限制作用、仅为了更好地理解本主题的示例被用来来解释本发明的主题。
本发明是一种状态跟踪系统(100)，其监测车辆中的悬挂和转向系统中的部件(200)的状况。这些部件(200)可以是承载或以其它方式受力的部件传感器(200)。随着时间的推移，这些部件(200)可能会产生裂纹，并且这种裂纹可能会导致事故。例如，在本发明的详细描述中，所述部件(200)是悬挂系统中的叉骨(悬架叉、悬架三角臂)。本发明也可以应用于不同的部件(200)。这里提到的车辆是陆地车辆，如汽车、公共汽车、卡车等。
参考图1，传感器单元(130)设置在部件(200)上。传感器单元(130)可以包括振动传感器(132)。传感器单元(130)还可以包括温度传感器(131)、声学传感器和磁场传感器(134)中的至少一个。传感器单元(130)可以设置在部件(200)中的槽中。在本发明的一可能的实施例中，传感器单元(130)可以通过粘合剂连接到部件(200)。
处理器单元(110)被配置为接收来自传感器单元(130)中的传感器的测量结果。处理器单元(110)可以是微处理器。处理器单元(110)与存储器单元(120)相关联，以读取和写入数据。处理器单元(110)获得关于其接收到的测量结果的测量信息。所述测量信息可以是转换到预定格式的测量的转换版本。在该示例性实施例中，测量信息可以是以预定时间间隔进行的测量的偏差(变化)。
存储器单元(120)包含参考值，该参考值包括作为测试结果获得的测量值和/或测量信息，其中在受控环境中用与传感器单元(130)类似的传感器对部件(200)进行测试。在这些测试中，部件(200)在正常操作条件下操作，并进行测量，通过施加各种效应和力进行测量，并且在几种情况下测量部件(200)的反作用力。因此，确定了部件(200)在正常工作、出现裂纹等条件下的测量特性，并且可以根据从传感器获得的测量值来确定阈值。例如，当振动传感器(132)与有裂纹的部件(200)相关联时，振动传感器(132)接收具有特定特性的振动测量。
在测试阶段，部件(200)在受力时的损坏、裂纹区域被检测为第一区域(210)。传感器单元(130)放置在上述第一区域(210)周围。
处理器单元(110)通过根据存储器单元(120)中的参考值对测量信息进行分类来创建状态信息。状态信息可以指示部件(200)有裂纹、部件(200)在正常条件下操作等。
状态跟踪系统(100)包括与处理器单元(110)相关联的用户接口(161)。用户接口(161)可以是连接到车辆的电子系统的显示器。处理器单元(110)也可以是车辆的电子控制单元。在可能的实施例中，用户接口(161)可以是用户终端(160)的显示器。上述用户终端(160)可以是移动电话、平板电脑等。状态跟踪系统(100)可以包括第一通信单元(151)，用于实现处理器单元(110)和用户终端(160)之间的通信。上述通信单元可以优选地使用短距离无线通信协议进行通信，该短距离无线通讯协议是本领域中已知的用于提供无线数据交换的协议之一。状态跟踪设备还可以包括第二通信单元(152)。第二通信单元(152)被配置为连接到诸如因特网之类的广域网或者连接到蜂窝网络。处理器可以经由第二通信单元(152)或第一通信单元(151)和用户终端(160)向服务器(300)发送测量信息或状态信息。因此，可以远程观察车辆中部件(200)的状况，并且从车辆上获得的测量值可以用于更新和增加参考值。在本发明的一可能的实施例中，存储器单元(120)可以位于服务器(300)上。在本发明的另一实施例中，服务器(300)周期性地更新车辆中的存储器单元(120)。
处理器单元(110)还可以与车辆传感器单元(140)相关联。车辆传感器单元(140)可以包括测量车辆状况的传感器。车辆传感器单元(140)可以包括测量车辆的启动和停止、速度、方位、方向盘的位置、相对于地面的倾斜、加速度、施加在其上的G力等的传感器。传感器单元(130)通过考虑其从车辆传感器接收的信息以及测量信息来产生状态信息。例如，当车辆在斜坡上行驶时的振动测量是相同的，即使部件(200)的状况可能根据车辆在平坦道路上行驶时所进行的振动测量而不同。车辆行驶的道路不平也可能是因素。处理器单元(110)通过考虑该信息来进行分类。
上述状态跟踪系统(100)操作如下：
当车辆启动时，处理器单元(110)从车辆传感器单元(140)接收关于车辆正在启动的信息。它接收来自传感器单元(130)的测量结果并获得测量信息，直到经过预定时间为止。在经过预定时间之后，它根据存储器单元(120)中的参考值对测量信息进行分类。它创建作为分类结果的状态信息，并使其能够显示在用户界面上(161)。例如，如果测量信息检测到其超过参考值中的阈值，则允许在用户界面(161)中生成警告以指示裂纹。所提到的警告可以是听觉的、视觉的、振动的等。状态信息也可以在用户界面(161)中指定，以指示部件(200)的剩余寿命。例如，由于分类的结果，如果所进行的测量与使用寿命略超过一半的部件(200)的特性相似，则可以通过确定剩余寿命的百分比来显示这些测量。
在本发明的一个可能的实施例中，过去的测量可以被即时发送到服务器(300)或用户界面(161)。
本发明的保护范围在所附的权利要求中进行了规定，并且不限于在上述详细描述中出于示例目的给出的说明。显然，本领域技术人员在会偏离本发明的主题的前提下，可以根据上述内容提出类似的实施例。
