具体实施方式
本发明的目的在于提供一种胎压监测集成装置，以提高胎压检测装置的可靠性。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1所示，本发明实施例公开了一种胎压监测集成装置，包括安装支架100、压力表200、压力传感器300和三通模块400。
其中，三通模块400具有第一气压输出口410、第二气压输出口420和气压输入口430，而气压输入口430与待测胎压设备连通，本实施例中，以气压输入口430与单轨车辆的走行轮胎的气门嘴软管连接为例进行介绍，为了保证气门嘴软管和三通模块400连接的稳定性，可用R型管卡对连接处进行固定。
压力表200的输入端与三通模块400的第一气压输出口410连通，压力表200安装时要保证完好的密封性，不能出现泄漏现象，以确保测量的准确性。压力表200内部安装了带电触点开关，在单轨车辆的走形轮胎的胎压保持在规定值时，压力表200内部的带电触点开关呈断开状态，但是，胎压低于规定值时，带电触点开关则变为闭合状态，并将此时的信号通过线路传输到列车网络监控主机，该系统检测到走行轮胎的气压值低于设定阈值时，将报警信息发送给列车车载控制器主机，以提醒驾驶员及时排查胎压风险。
由于单轨车辆车身较长，因此单轨车辆一般安装有信号传输设备，信号传输设备的主要功能可以延长信号传输距离，实现较长距离的通信，提高信号的传输效率。信号传输设备将接收到的压力表200的低压警报信息传输到驾驶室内的显示设备上。
压力传感器300是能感受压力信号，并能按照一定的规律将压力信号转换成可用的输出的电信号的器件或装置，且通常由压力敏感元件和信号处理单元组成。压力传感器300的输入端与三通模块400的第二气压输出口420连通，并将检测信号以无线传输的形式，传输至信号传输设备。
因此，本发明提供的胎压监测集成装置，通过三通模块400实现压力表200的输入端与待测胎压设备相连通，以检测该待测胎压设备的胎压，并由线路连 接到信号传输设备，同时，通过三通模块400将压力传感器300的输入端与待测胎压设备相连通，该压力传感器300的检测信号通过无线传输的方式传输至信号传输设备。因此，本发明提供的胎压监测集成装置集成了有线传输的压力表200和无线传输的压力传感器300同时对待测胎压设备进行胎压检测，既能够避免因有线传输信号的压力表200的线缆破损导致的胎压异常信息无法及时传递的问题，又能够弥补无线传输信号的压力传感器300检测不准确的问题，提高了胎压检测装置的可靠性。
为了便于对本发明提供的胎压监测集成装置的维护，三通模块400设置为三通阀，且设置了三种工作状态。第一种工作状态，三通阀的第一气压输出口410、第二气压输出口420和气压输入口430相互连通，此时，压力表200和压力传感器300同时检测走行轮胎的胎压。第二种工作状态，三通阀的第一气压输出口410与气压输入口430相连通，且第二气压输出口420与气压输入口430相截止，此时，压力表200正常检测胎压，压力传感器300停止检测工作，可对压力传感器300拆卸进行更换或维修。第三种工作状态，三通阀的第一气压输出口410与气压输入口430相截止，且第二气压输出口420与气压输入口430相连通，此时，压力表200停止检测胎压工作，压力传感器300处于正常检测工作状态，可对压力表200拆卸进行更换或维修。
另外，为了便于对三通阀的三种工作情况的可控制选择处理，三通阀为手动控制阀，并将三通阀的控制端安装在驾驶室内，方便工作人员根据实际需求切换三通阀的工作状态。三通阀的控制端可为常用的控制杆，例如将控制杆拨动至左侧时，三通阀处于第二工作状态，三通阀的第一气压输出口410与气压输入口430相连通，且第二气压输出口420与气压输入口430相截止；将控制杆拨动至右侧时，三通阀处于第三工作状态，三通阀的第一气压输出口410与气压输入口430相截止，且第二气压输出口420与气压输入口430相连通；将控制杆拨动至中间时，三通阀处于第一工作状态，三通阀的第一气压输出口410、第二气压输出口420和气压输入口430均相互连通。
如图1所示，将压力表200、压力传感器300和三通模块400均固定在安装支架100上，以此，便于工作人员对本发明提供的胎压监测集成装置的各个工作单元，进行统一检测和维护，减少了维护工作量，提升维护工作的效率，即通过对安装支架100的拆装，可实现对整个胎压监测集成装置的拆装。
在一具体的实施例中，安装支架100设置有安装部，用于安装压力表200、压力传感器300和三通模块400，且安装支架100通过连接部110以焊接方式固定到支架底板120上，又或者是本领域技术人员常用的其他固定方式，在此不做更具体的限定。
为了不对支架底板120上的零件产生干涉，连接部110与安装支架100的安装部具有夹角，在将连接部110焊接于支架底板120上后，使得在连接部110的支撑作用下，安装部与支架底板120之间形成用于避让周围零件的避让空间。且此设计形成了层叠结构，避免了安装支架100横向展开占用单轨车辆底架更多空间，实现机械结构紧凑，挺高空间利用率。
由于压力传感器300内部布置有复杂的电路系统，避免单轨车辆传输线路出现破损后通过安装支架100或者与安装支架100连接的三通模块400，将电导通到压力传感器300上，进而对压力传感器300内部的电路系统造成破坏，所以在压力传感器300和三通模块400与安装支架100之间设置有第一绝缘垫500。此外，第一绝缘垫500兼具减振作用，减少车辆行驶中车体振动对压力传感器300和三通模块400内部零件的影响。
如图2和图3所示，压力传感器300和三通模块400与安装支架100均通过第一紧固件600固定，可方便对压力传感器300和三通模块400的拆卸。第一紧固件600可采用螺栓配合平垫和弹簧垫圈使用，防止了因车体振动而造成螺栓松动，不能牢固紧固的问题。又或者是本领域技术人员常用的其他紧固件，在此不做更具体的限定。
同理，为了防止传输线路破损后漏电通过第一紧固件600导通到压力传感器300，在第一紧固件600与安装支架100的贴合面、第一紧固件600与压力传感器300的贴合面以及第一紧固件600与三通模块400的贴合面之间均通过套设于第一紧固件600上的第一绝缘套610绝缘隔开。
如图4和图5所示，压力表200需要安装导线，为了防止接线处的电导通到安装支架100上，因此，在压力表200与安装支架100之间设有第二绝缘垫700，且压力表200的输出导线设置在第二绝缘垫700背对安装支架100的一侧。
压力表200通过第二紧固件800安装在安装支架100，第二紧固件800可采用螺栓配合平垫和弹簧垫圈使用，同理，可避免因车体振动而造成螺栓松动，不能稳定固定的问题。并且，为了防止压力表200的电流通过第二紧固件800导通 到安装支架100上，在第二紧固件800与安装支架100的贴合面通过套设在第二紧固件800上的第二绝缘套810实现电流绝缘隔开。
如图6所示，在另一具体的实施例中，在支架底板120上设置有滑环900，滑环900主要由转子与定子两大部分组成，能够在转动状态下传输信号的电连接器，使得传输信号的线路不会发生扭绞和缠绕。因此，可防止本发明提供的胎压监测集成装置的线路，不会出现扭绞和缠绕的现象。所以压力表200的线路线连接至滑环900上，然后滑环900的线路连接至传输设备上，以完成信号的传输。
单轨车辆的走行轮为并列两组，因此，安装支架100上设置有两组压力表200、压力传感器300和三通模块组成的检测模块，且两组检测模块共用一个滑环900。两组检测模块与滑环900的线路连接如图6所示，两组压力表200的正极极柱通过线路分别连接到滑环900的两个输入正极极柱，滑环900的两个输入正极极柱通过内部线路导通于滑环900的输出正极极柱，而两组压力表200的负极极柱通过线路串联连接，滑环900的输入负极极柱连接到其中一组压力表200的负极极柱，然后滑环900的输入负极极柱通过内部的线路与滑环900的输出负极极柱连通，最后滑环900的输出正极极柱和输出负极极柱通过线路连接到信号传输设备上，使得两组检测模块线路的并联，实现了对两组走行轮胎的胎压分别检测。
