下面结合图1至图5进一步解释如何通过智能手机上装在APP来实现TPMS的升级，为阐述方便，在下列中，以传感器来表示上面的传感单元、以智能手机来表示上述的升级单元。
首先，用户在应用市场找到APP下载安装在智能手机上。然后打开APP客户端，可以看到众多的操作界面，如注册/游客/登录、APP版本更新、TPMS版本更新、手动选择车型、输入车型自动搜索、历史数据的分支操作界面。
附：设置好车型和年份（本实施例中要求用户一定要根据车型和年份设置，每个车的TPMS协议都不一样，本实施例中的升级就是根据车型来烧入协议）；而在本实施例中升级模式分别有自动式升级、手动式升级、复制式升级，每个升级模式的都是根据实际需要来使用的；自动式升级是随机生成一个ID码写入传感器中，整个升级过程不需要任何操作，直至到结果的反馈；手动式升级是根据用户的实际需要输入一个ID码写入传感器之中；复制升级，复制已有传感器的所有信息，烧入新的传感器，用来替代原来的传感器；检测模式是用来读取传感器信息。
如图5所示，为本发明实施里提供的一种基于智能手机蓝牙或WiFi设备升级TPMS传感器的升级系统的升级方法，该升级系统包括传感器、转换单元、智能手机/平板电脑。具体的实施步骤如下：
a.用户打开APP登录帐号，检查更新和TPMS协议更新，再打开蓝牙或者WIFI搜索到转换单元并进行连接。
b.手动选择车型或者输入车型自动搜索年份，因为每个车的TPMS协议都不一样,所以根据自己的车型和年份设置好，或者可以查看历史数据。
c.根据实际需要选择升级模式分别有自动式升级、手动式升级、复制式升级。具体的升级模式如下：
c1.当用户选择自动式升级模式时，自动式升级是随机生成一个ID码写入传感器中。实现过程如下：在APP之中选中所升级的车型和年份，再选择自动式升级模式会随机生产一个ID附带协议通过蓝牙或者WIFI上传至转换单元，经过转换单元主芯片的处理把信号处理成传感器所接收的低频信号再上传至传感器更改掉原来所有的ID和发送信号的协议，成为现在升级车型的协议，ID也将换成随机产生的ID。后续传感器会通过传感器的高频模块发射一个高频信号反馈升级结果给转换单元，通过转换单元的主芯片再转换成蓝牙或者WIFI发送给APP呈现出可视数据反馈升级结果信息。如果升级成功则会反馈升级完毕，负责升级失败。
c2.当用户选择手动式升级模式时，手动式升级是根据用户的需要输入一个ID码写入传感器之中。在APP之中选择需要的车型和生产年份，再选择手动式升级。这时就需要用户手动输入一个ID码，确定升级后输入的ID码和协议就可通过蓝牙或者WIFI上传至转换单元，经过转换单元的主控芯片模块的运算处理再转换成低频信号上传至传感器，传感器再根据接收到的更改指令更改成所选车型的传感器协议和手动输入的ID码。上传完成后传感器高频模块也会发送一个高频信号反馈升级结果给转换单元，通过转换单元主控芯片模块再转换成蓝牙或者WIFI发送给APP呈现出可视数据反馈升级结果信息。如果升级成功则会反馈升级完毕，否则升级失败。
c3.当用户选择复制升级模式时，复制旧的传感器的所有信息，烧入新的传感器，用来替代旧的传感器。先在APP之中选择复制式升级模式，APP就会发送一个指令通过蓝牙或者WIFI给转换单元，再通过转换单元的主芯片把这个指令处理成低频信号通过低频模块发送给旧传感器，旧传感器接收到指令会把自带信息通过传感器自带的高频模块反馈给转换单元，再通过转换单元转换成蓝牙或者WIFI反馈给智能手机用以呈现，然后APP的相关功能把反馈的信息复制下来。再将新复制到的信息升级到新的传感器，这时刚刚读取复制的信息又通过蓝牙或者WIFI把信息传递给转换单元，通过转换单元的主芯片模块的转换把信息转换成低频信号，通过低频模块上传到新的传感器替换掉新的传感器本来的信息。这样就完成一个复制的传感器了。同样的复制升级数据上传后传感器也会通过传感器的高频模块反馈新的信息给转换单元，经过转换单元主控的转换成蓝牙或者WIFI发送给APP端呈现出来。如果升级成功则会反馈升级完毕，否则升级失败。
c4.另外用户选择进入检测模式时，就会通过智能终端的蓝牙或者WIFI发送一个检测信号给转换单元，经过转换单元把这个指令处理成低频信号通过转换单元的低频模块把传感器唤醒，传感器接收到指令再把自己夹带的信息通过传感器的高频模块回传给转换单元。经过转换单元主芯片的处理成蓝牙或者是WIFI传递给发送指令的APP的智能终端。
需要说明的是，本发明基于智能手机蓝牙或WiFi设备升级TPMS传感器的方法及装置，通过手机或者平板电脑下载安装APP客户端，选择车型、年份进行升级，可兼容市面上的任何车型的TPMS系统，实现了对TPMS传感器的通用，尤其是在检测，售后升级维修。整个数据库来源于网络，实时更新数据，不存在滞后的缺点，载体为手机，应用性广泛，成本低。具备自动式升级、手动式升级、复制式升级、检修模式，双向通讯的功能。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
