下面以具体地实施例对本发明的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本发明的实施例进行描述。
图2为本发明实施例一提供的胎压传感器的识别方法的流程图，如图2所示，本实施例中的方法可以包括：
S101、向待测胎压传感器发送激活信号，直到接收到所述待测胎压传感器发送的针对激活信号的反馈信号；其中，所述反馈信号中包括所述待测胎压传感器的特征信息。
本实施例中，可以采用微控制单元MCU按照预设的策略向所述待测胎压传感器发送激活信号。其中，胎压传感器仅会被与其对应的波形的激活信号激活，并针对该激活信号发送反馈信号。需要说明的是，本实施例不限定与胎压传感器对应的波形数量。一个胎压传感器可以与一个或多个波形对应。一般情况下，不同胎压传感器厂商的激活波形各不相同，因此激活波形与胎压传感器厂商之间也会存在对应关系。因此，微控制单元MCU可以从本地存储器中获取预先存储的不同胎压传感器所对应的激活波形，也可以联网后从云端获取不同胎压传感器所对应的激活波形；然后根据所述激活波形来生成对应的激活信号，用以激活所述待测胎压传感器。当MCU发送的激活信号与所述待测胎压传感器的目标激活信号的波形一致时，该待测胎压传感器会向MCU发送反馈信号。
一种实施方式中，激活信号可以为低频信号，微控制单元可以通过控制低频发射模块向待测胎压传感器发送激活信号，即低频信号。
在此，微控制单元向待测胎压传感器发送激活信号可以通过低频发射模块 广播激活信号，以使待测胎压传感器可以接收到激活信号；或者，微控制单元可以通过低频发射模块直接向胎压传感器发送激活信号。
在一种实施方式中，MCU依次向所述待测胎压传感器发送市场占比率由高至低的胎压传感器对应的激活信号。
具体地，微控制单元MCU获取市场上不同胎压传感器所对应的激活波形；生成与所述激活波形对应的激活信号；然后根据所述不同胎压传感器的市场占比率的大小顺序，依次向所述待测胎压传感器发送所述激活信号，直到接收到所述待测胎压传感器发送的反馈信号。微控制单元MCU通过低频发射模块生成与激活波形对应的激活信号。
在本实施例中，以不同胎压传感器的市场占比率顺序生成对应的激活信号。理论上，汽车使用市场占比率越高的胎压传感器的概率最大，因此，为了缩短对待测胎压传感器的扫描时间，按照市场占比率最高的胎压传感器所对应的激活波形生成激活信号，然后将该激活信号发送给所述待测胎压传感器，可以提升胎压传感器的识别效率。
在另一种实施方式中，在MCU向待测胎压传感器发送激活信号之前，可以接收用户输入的待测胎压传感器的标识信息；然后根据所述标识信息确定与所述标识信息对应的激活信号。
具体地，当微控制单元MCU根据所述不同胎压传感器的市场占比率的大小顺序，依次向所述待测胎压传感器发送所述激活信号，并且没有收到反馈信号时，或者，在MCU发送激活信号之前，可以提示用户输入待测胎压传感器的标识信息，例如，通过显示模块提示用户输入标识信息，以减小匹配的范围或者增加匹配速度。MCU可以通过输入模块来接收用户输入的标识信息。MCU接收到用户输入的待测胎压传感器的标识信息后，可能出现以下两种情况：
第一种情况，待测胎压传感器的标识信息对应唯一的激活信号，此时，将该激活信号发送给所述待测胎压传感器。
第二种情况，待测胎压传感器的标识信息对应的激活信号的数量大于1，此时，可以依次向所述待测胎压传感器发送市场占比率由高至低的胎压传感器对应的激活信号。
本实施例中，标识信息可以是车辆信息和/或所述待测胎压传感器的生产厂商信息。
其中，车辆信息可以包括车型、车款等信息。由于车辆在出厂前可以安装有胎压传感器，此类胎压传感器也可以被称为原装传感器，因此，微控制传感器可以通过车辆信息，确定胎压传感器的型号或规格或限定胎压传感器的型号范围，进而可以确定针对胎压传感器的激活信息，进而可以提升激活信号的发送准确性，以进一步提升胎压传感器的识别效率。
其中，胎压传感器的生产厂商信息可以包括生产厂家标识，批次号等信息。同理，通过生产厂商信息，确定胎压传感器的型号(或称为类型)或规格或限定胎压传感器的型号范围，进而可以确定针对胎压传感器的激活信息，进而可 以提升激活信号的发送准确性，以进一步提升胎压传感器的识别效率。
本实施例中，可以通过设置扫描条件，来缩小扫描的范围，从而加快对所述待测胎压传感器的扫描过程。在本实施例中通过用户输入的车辆信息和/或待测胎压传感器的生产厂商信息来限制激活波形的数量。
在又一种实施方式中，微控制单元MCU通过电连接的用户交互模块接收用户输入的所述待测胎压传感器的零件号；根据所述待测胎压传感器的零件号，获取与所述待测胎压传感器的零件号对应的激活波形；生成与所述激活波形对应的激活信号后，将所述激活信号发送给所述待测胎压传感器。
本实施例中，由于胎压传感器的零件号可以直接得到对应的胎压传感器的类型，以及其适用的激活工具，因此，当获知待测胎压传感器的零件号时，微控制单元MCU可以直接根据用户输入的所述待测胎压传感器的零件号，生成相应的激活信号来扫描待测胎压传感器。
S102、根据所述特征信息，识别所述待测胎压传感器。
在一种实施方式中，可以将所述特征信息与预存的参考特征信息进行匹配；若匹配成功，则根据与所述参考特征信息对应的胎压传感器的标识信息，识别所述待测胎压传感器。
在另一种实施方式中，所述特征信息可以包括：数据特征信息和传感器状态信息。此时，可以将所述传感器状态信息与预存的参考特征信息中的参考传感器状态信息进行匹配；若匹配成功，则进一步地将所述数据特征信息与预存的参考特征信息中的参考数据特征信息匹配。
其中，数据特征信息可以包括：波特率，调制方式，包长，帧长，帧头，帧尾，帧间隔，帧计数中的至少一个。所述胎压传感器的状态信息包括：存储模式、停车模式、暂停模式中的至少一个。
具体地，波特率也称为调制速率，波特率是指数据信号对载波的调制速率，它用单位时间内载波调制状态改变的次数来表示，其单位是波特(Baud)。调制方式包括：调频、调幅、调相三种。包长是指数据包包含的字节数，用于表征数据包的大小。帧长是指数据帧的长度，数据帧是数据链路层的协议数据单元。数据帧包括：帧头、数据部分，以及帧尾，帧头和帧尾包含一些必要的控制信息，比如同步信息、地址信息、差错控制信息等。帧间隔可以用相邻数据帧之间的发送时差来表示，也可以用相邻的数据帧之间间隔的P帧数量来表示。帧计数可以是统计一秒内输出的帧数。
可选地，可以识别所述待测胎压传感器的类型；或者，识别所述待测胎压传感器的通信协议。当知道所述待测胎压传感器的类型或者所述待测胎压传感器的通信协议时，及可以确定其对应的激活信号。
本实施例中，将所述特征信息与预先存储的不同胎压传感器的参考特征信息进行一一比对，直到得到与所述特征信息完全匹配的参考特征信息所对应的胎压传感器的类型或者通信协议。
具体地，胎压传感器的状态信息是通过其对应的状态字来表征的，例如： 胎压传感器的状态字可以用来表征当前胎压传感器所处的状态。具体地，假设用字符串AA、BB、CC分别表示胎压传感器处于存储模式、停车模式、暂停模式。而不同的胎压传感器用不同的状态字来表征这三种模式。因此，可以根据待测胎压传感器处于存储模式、停车模式、暂停模式时对应的状态字来区分不同的胎压传感器。其中，存储模式是指胎压传感器已经通过数据线与MCU建立通信连接，此时胎压传感器类似于外接的存储器，MCU可以读取出胎压传感器中的数据。停车模式是指胎压传感器在车辆处于停车状态时的工作模式，暂停模式是指胎压传感器被暂停使用时的工作模式。
当然，胎压传感器的状态信息还可以包括其他模式，如行车模式、运动模式等。
一种实施方式中，可以首先根据胎压传感器的状态信息确认胎压传感器的状态，当确定胎压传感器处于存储模式、停车模式、暂停模式中的任意一种模式下时，可以进一步地根据数据特征信息对胎压传感器进行识别。若确定胎压传感器不处于上述任意一种状态时，则不对胎压传感器进行识别，进一步地，可以提示用户当前无法识别或者识别失败。
将数据特征信息与预设的参考特征信息进行匹配，若匹配成功，可以确定胎压传感器的类型、规格、标识等信息。在识别出胎压传感器后，可以进一步地解析出胎压传感器发送的其他数据，如胎压传感器反馈的轮胎压力信息、温度信息、胎压传感器的电量信息、匹配车型信息等。
进一步地，还可以根据胎压传感器的唯一识别号ID信息，来识别待测胎压传感器的类型。其中，所述胎压传感器的唯一识别号ID信息包括：ID的起始位置和长度信息。当知道胎压传感器的ID信息时，即可确定胎压传感器待测胎压传感器的类型和通信协议。
具体地，假设所述特征信息包含N项特征，N为大于等于1的自然数；预先存储的不同胎压传感器的参考特征信息包含M项特征，且M的值大于或者等于N。若从参考特征信息的M项特征中找到N项特征与所述特征信息的N项特征全部匹配，则将该参考特征信息所对应的胎压传感器的类型作为所述待测胎压传感器的扫描结果。
本实施例，通过向待测胎压传感器发送激活信号，直到接收到所述待测胎压传感器发送的针对激活信号的反馈信号，其中，所述反馈信号中包括所述待测胎压传感器的特征信息；根据所述特征信息，识别所述待测胎压传感器。本发明实现了对胎压传感器的自动扫描，并能够根据扫描结果准确识别出胎压传感器，进而提升对胎压传感器的激活效率。
