具体实施方式
下面将参照相关附图对本发明实施例进行描述。
请参阅图1，图1为本申请实施例提供的一种胎压接收器的结构示意图。
如图1所示，胎压接收器10，包括主控单元102、胎压接收单元103及无线通信单元101。
其中，无线通信单元101可以实现与终端通信连接。具体地，无线通信单元101用于接收终端发送的第一指令，并将第一指令传输至主控单元102。
终端可以包括用户终端，如智能手机，平板电脑等终端设备。无线通信单元101可以基于无线通信技术与终端实现连接。例如，无线通信单元101可以是蓝牙单元，即无线通信单元101基于蓝牙技术与终端实现通信；或者，无线通信单元101可以是WiFi单元，即无线通信单元101基于WiFi技术与终端实现通信；或者，无线通信单元可以是Zigbee单元，即无线通信单元101基于Zigbee技术与终端实现通信；当然，无线通信单元101还可以是支持其他通信技术或通信协议的结构，在此不予限定。
其中，无线通信单元101可以通过专用集成电路(Application-specific integrated circuit，ASIC)、现场可编程门阵列(Field-Programmable Gate Array， FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件等结构实现，在此不予限定。
无线通信单元101还可以用于接收终端发送的其他指令，并可以根据通信协议解析该指令，并可以将解析后的指令发送给主控单元102，以由主控单元102对该指令进行进一步处理。
在此，终端发送的第一指令可以用于指示主控单元102对胎压传感器的身份信息进行更新。
主控单元102用于接收第一指令，并根据第一指令对胎压传感器的身份信息进行更新。
示例性地，胎压传感器的身份信息可以包括胎压传感器的标识、胎压传感器的安装位置信息等中的一种或多种，在此不予限定。其中，胎压传感器的标识可以是指用以表征一个胎压传感器的唯一标识，或者是指胎压传感器的可编写标识，在此不予限定。例如，胎压传感器的安装位置信息可以用于表征胎压传感器被安装在车辆的左前轮胎、右前轮胎、左后轮胎、右后轮胎等。其中，主控单元102对胎压传感器的身份信息进行更新可以是对身份信息中的一种或多种信息进行更新，在此不予限定。
一种场景下，若需要对车辆上的胎压传感器进行更换，终端可以接收用户输入的更换后的胎压传感器的身份信息，例如，胎压传感器的标识等。并将该更换后的身份信息携带在第一指令中发送给无线通信单元101。
一种实现方式中，无线通信单元101可以从第一指令中解析出该指令用于对胎压传感器的身份信息进行更新，并可以解析出更换后的身份信息，无线通信单元101可以对其解析。无线通信单元101将解析后的信息发送给主控单元102。
另一种实现方式中，无线通信单元101可以将第一指令发送给主控单元102。由主控单元102解析第一指令，并执行该第一指令。
举例说明，第一指令可以用于指示更新安装位置在左前车轮的胎压传感器 的标识，则第一指令可以携带有胎压传感器的安装位置信息为左前车轮，新胎压传感器的标识等。无线通信单元101可以接收到终端发送的第一指令，并将该第一指令发送给主控单元102。主控单元102即可根据安装位置信息确定待更新标识的胎压传感器，并对该胎压传感器的标识进行更新，更新为第一指令中携带的标识。具体地，可以预建立胎压传感器的标识与安装位置信息的对应关系表，根据该对应关系表对胎压传感器的标识进行更新。
主控单元102还用于通过胎压接收单元103接收与身份信息更新后的胎压传感器对应的胎压信息。
示例性地，主控单元102在根据第一指令对胎压传感器的身份信息进行更新后，可以通过胎压接收单元103接收胎压传感器发送的胎压信息，该胎压信息可以包括胎压传感器采集的轮胎温度、轮胎压力或其他环境信息等。该胎压信息还可以携带有胎压传感器的身份信息，例如，携带有胎压传感器的标识。
主控单元102可以将胎压信息所携带的胎压传感器的标识与更新后的胎压传感器的身份信息进行匹配。若胎压信息所携带的胎压传感器的标识与更新后的一个胎压传感器的身份信息匹配成功，则主控单元102可以基于该胎压传感器的标识，确定对应的胎压传感器的安装位置信息，进而可以根据接收到的胎压信息获知对应轮胎的状态。
举例说明，主控单元102将胎压传感器的标识与预建立的对应关系表依次进行匹配，若该标识与对应关系表中的标识匹配成功，则可以确定胎压传感器的安装位置信息，例如胎压传感器安装在左前车轮，则主控单元102可以获知接收到的胎压信息属于左前车轮，进而可以根据胎压信息判断左前车轮的当前状态。
其中，胎压接收单元103可以利用单向传输技术接收胎压传感器的信息。
主控单元102可以是由处理器、控制器、中央处理单元(Central Processing Unit，CPU)、专用集成电路、现场可编程门阵列或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件等组件实现的，在此不予限定。
在上述胎压接收器中，用户可以通过终端更新胎压接收器中的胎压传感器的身份信息，简化胎压接收器与胎压传感器之间的匹配过程，提升用户体验。
请参阅图2，图2为本申请实施例提供的另一种胎压接收器的结构示意图。
如图2所示，胎压接收器10包括：包括主控单元102、胎压接收单元103、无线通信单元101、存储单元104及车载设备通信单元105。
其中，主控单元102、胎压接收单元103及无线通信单元101与图1中的功能原理一致，在此不再赘述。
存储单元104用于存储主控单元102发送的更新后的胎压传感器的身份信息。
具体地，存储单元104可以存储主控单元102发送的更新后的胎压传感器的身份信息。从而，主控单元102在通过胎压接收单元103接收到一个胎压传感器的胎压信息时，可以调用存储单元104存储的身份信息，确定该胎压信息所携带的胎压传感器的身份信息是否与存储单元104存储的身份信息匹配，若匹配，则可以识别出该胎压传感器所属轮胎，进而可以根据接收到的胎压信息确定该轮胎的状态。
存储单元104还用于存储主控单元102发送的与身份信息更新后的胎压传感器对应的胎压信息。
具体地，主控单元102通过胎压接收单元103发送的胎压信息，可以首先确定胎压信息中的身份信息是否与存储单元104存储的身份信息相匹配。若相匹配，则主控单元103将该胎压信息存储至存储单元104中。进一步地，主控单元103还可以从存储单元104中读取所存储的胎压信息并进行进一步处理。例如，根据胎压信息判断轮胎是否出现异常等。
当有新的胎压信息要写入存储单元104时，存储单元104可以将新的胎压信息写在原胎压信息的地址上，以覆盖原胎压信息，进而节省存储空间。或者，存储单元104可以同时存储新的胎压信息以及原胎压信息。存储单元104对胎压信息的存储方式可以与存储单元104的硬件实现相关，在此不予限定。
具体地，在数字系统中，只要能保存二进制数据的都可以是存储单元104；在集成电路中，一个没有实物形式的具有存储功能的电路也叫存储单元104，如RAM(Random Access Memory易挥发性随机存取存储器)、FIFO(First Input First Output，先进先出)存储器等；在系统中，具有实物形式的存储设备也叫存储单元104，如内存条、内存卡等。
胎压接收器10还可以包括车载通信单元105。车载设备通信单元105用于接收主控单元102发送的胎压信息，并将胎压信息发送至车载显示设备中，使胎压信息在车载显示设备中进行显示。具体的，车载显示设备可以通过车载设备通信单元105与胎压接收器10进行数据交互。车载通信单元105可以由现场总线接口、RS232接口或串行接口等实现。当然，车载通信单元105还可以包括其他的实现方式，如车载通信单元105为无线接口等，车载通信单元105可以实现与车载显示设备进行有线连接或无线连接，在此不予限定。
可选地，胎压接收器10可以包括显示单元，主控单元101用于控制该显示单元显示胎压信息，或显示主控单元101对胎压信息的处理结果等。在此种情况下，胎压接收器10无需通过车载显示设备进行显示，提升了用户体验。
结合上述胎压接收器的结构，在本实施例中，无线通信单元101还用于接收终端的第二指令，并将第二指令发送至主控单元102。
第二指令用于控制主控单元102读取胎压信息，如用户需要知道左前轮的胎压信息时，由于胎压传感器的数据是定时或实时更新的，并不停的将更新的胎压信息发送给胎压接收器10。因此，能够通过终端控制主控单元102去读取左前轮的胎压信息。在读取成功后，可通过无线通信单元101发送给终端。
一种实现方式中，无线通信单元101可以从第二指令中解析出该指令用于读取胎压传感器获取的胎压信息，无线通信单元101可以对该指令进行解析。无线通信单元101将解析后的信息发送给主控单元102。主控单元102根据该信息去获取胎压接收单元103接收的信息。而胎压接收单元103是定时、不定时或实时接收胎压传感器的数据，该数据包括胎压信息，因此，根据第二指令， 可由主控单元101根据胎压接收单元103获取胎压传感器定时、不定时或实时发送的数据，进而获取定时、不定时或实时的胎压信息。
另一种实现方式中，无线通信单元101可以将第二指令发送给主控单元102。由主控单元102解析第二指令，并执行该第二指令。
举例说明，第二指令可以用于获取安装位置在左前车轮的胎压传感器的胎压信息。无线通信单元101可以接收到终端发送的第二指令，并将该第二指令发送给主控单元102。主控单元102即可根据第二指令确定需要获取胎压信息的为左前车轮。从而，主控单元102从存储单元104中读取左前车轮的胎压信息。
主控单元102还用于通过无线通信单元101向终端发送根据第二指令所读取的胎压信息。
示例性地，主控单元102在根据第二指令对胎压信息进行读取后，可以通过存储单元104存储的胎压信息获取每个胎压传感器的数据，该数据可以包括实时的胎压信息，也可以是特定时刻的胎压信息。因而，可根据用户需要的胎压信息进行读取，并经由无线通信单元101以第二指令的形式向终端发送。
举例说明，主控单元102解析出第二指令是需要读取左前车轮的胎压信息时，主控单元102从存储单元104中读取左前车轮的胎压信息，可以是实时的胎压信息，也可以是特定时刻的胎压信息。主控单元102将读取的左前车轮的胎压信息经由无线通信单元101向终端发送。
或者，该第二指令中可以指示所要读取的胎压信息所属的轮胎信息、所要读取的胎压信息的数量、所要读取的胎压信息的时间等，主控单元101可以根据第二指令，从存储单元104中读取除第二指令所指示的胎压信息，并通过无线通信单元102发送给终端，从而终端可以获取所需的胎压信息。
无线通信单元101还用于接收第三指令，并将第三指令发送至主控单元102。
主控单元102用于根据第三指令，确定待显示的胎压信息，并将待显示的 胎压信息发送至车载设备通信单元105，车载设备通信单元105将带显示的胎压信息发送至车载显示设备中以进行显示。
主控单元102还用于根据第三指令，确定待显示的胎压信息的显示方式，并通过车载设备通信单元105，将显示方式发送至车载显示设备，以使车载显示设备按照显示方式对胎压信息进行显示。
具体的，显示方式为灯光闪烁或是数字显示等，在此，对胎压信息的显示方式不予限定。即第三指令还可以用于指示其他显示方式，在此不予限定。
第三指令用于控制主控单元102确定待显示的胎压信息，如用户需要知道左前轮的胎压信息时，终端可以生成第三指令，并将第三指令发送至胎压接收器10的无线通信单元103中。因此，主控单元102通过无线通信单元103接收到该读取左前轮的胎压信息。在读取成功后，可通过车载设备通信单元105发送给车载显示设备进行显示。
一种实现方式中，无线通信单元101可以从第三指令中解析出该指令用于确定待显示的胎压信息，无线通信单元101可以对该指令进行解析。无线通信单元101将解析后的信息发送给主控单元102。主控单元102根据该信息去获取存储单元104存储的胎压信息。因此，根据第三指令，可由主控单元101根据胎压接收单元103获取胎压传感器定时或实时发送的数据，进而获取待显示的定时或实时的胎压信息。
另一种实现方式中，无线通信单元101可以将第三指令发送给主控单元102。由主控单元102解析第三指令，并执行该第三指令。
举例说明，第三指令可以用于获取安装位置在左前车轮的胎压传感器的胎压信息。无线通信单元101可以接收到终端发送的第三指令，并将该第三指令发送给主控单元102。主控单元102即可根据第三指令确定待显示的胎压信息，且该胎压信息对应为左前车轮的胎压信息。从而，主控单元102从存储单元104中读取左前车轮的胎压信息，并确定为待显示的胎压信息。
示例性地，主控单元102在根据第三指令对确定待显示的胎压信息后，可 以通过存储单元104存储的胎压信息获取每个胎压传感器的数据，该数据可以包括实时的胎压信息，也可以是特定时刻的胎压信息。因而，可根据用户需要显示的胎压信息进行读取，并经由车载设备通信单元105车载显示设备发送。
举例说明，主控单元102解析出第三指令是需要显示左前车轮的胎压信息时，主控单元102从存储单元104中读取左前车轮的胎压信息，可以是实时的胎压信息，也可以是特定时刻的胎压信息。主控单元102将读取的左前车轮的胎压信息经由车载设备通信单元105向车载显示设备发送，并由车载显示设备进行显示。
胎压接收器10还包括：电源单元，用于为主控单元102供电。当然，该电源单元也可以为胎压接收器10中的其他单元进行供电，在此不予限定。胎压接收器10通过电源单元实现独立工作。
可选地，胎压接收器10还可以包括电源接口，该电源接口可以与车载设备连接，从而由车载设备来对胎压接收器10进行供电。
胎压接收器10可以兼容上述供电方式，即胎压接收器10包括电源单元和电源接口，在主控单元102监测到电源单元供电不足的情况下，切换至电源接口，由车载设备为其供电。或者，胎压接收器10可以通过上述任意一种方式实现供电，在此不予限定。
胎压接收单元103包括射频接收单元。
无线通信单元101包括蓝牙单元、无线保真WiFi单元、ZigBee单元中的至少一种。无线通信单元101是与终端进行通讯的，因此，可采用终端上各种通讯协议，包括但不限于蓝牙单元、无线保真WiFi单元、ZigBee单元中的一种。
基于上述实施例，胎压接收器10的工作原理如下：
在用户进行胎压传感器的更换后，终端向无线通信单元101发送第一指令，该第一指令包含胎压传感器的身份信息，使得通过无线通信单元101接收第一指令后的主控单元102对胎压传感器的身份信息进行更新。同时，由于更 换后的胎压传感器定时、不定时或实时向胎压接收器10发送胎压信息，因而胎压接收器10将接收的胎压信息发送给主控单元102，由主控单元102对当前胎压传感器传输的胎压信息作进一步的判断，并由存储单元104进行存储。
进一步的，终端发送第二指令后，主控单元102会将当前接收的胎压信息发送到终端，使终端进行显示。
终端发送第三指令后，主控单元102会根据第三指令确定待显示的胎压信息，并将待显示的胎压信息发送至车载设备通信单元。使得用户能够通过车载设备的显示获取胎压信息，方便用户用户驾驶过程中查看当前胎压信息。
