一种新型便携式程序升级方法 技术领域
本发明属于电子技术领域，涉及一种新型便携式程序升级方法。
背景技术
成熟的电子设备，总会伴随着大量的测试、修改、再测试、再修改的过程。只有经过实车验证的产品，才是稳定可靠的。
传统的电子产品，一旦出现问题就得拆卸外壳，损伤的外观或结构，直接导致产品的报废，浪费大量的时间和金钱。
目前汽车上许多电子设备都带有LIN或CAN总线，利用总线通信的方式，在不需要拆卸的情况下就可实现远程升级，达到原先拆卸维修一样的目的，既方便又便捷。
一般售后维修人员的知识储备相对欠缺，如果每个人都匹配一台电脑，利用PC端的上位机实现远程升级，对人员的要求未免有点苛刻，操作的繁琐容易造成升级失败的情况。
发明内容
本发明为解决上述技术问题，本发明的目的是提供一种新型便携式程序升级方法，解决了通过一款便携式升级设备对多款不同的待升级设备进行程序升级，保证程序升级准确的技术问题。

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-图5所示的一种新型便携式程序升级方法，包括如下步骤：
步骤1：在便携式升级设备中设立协议包池，协议包池包括协议包数据库和加密心跳协议数据库，在加密心跳协议数据库中存储多个加密心跳协议，在协议包数据库中存储多个协议包；在协议包池中建立协议包与加密心跳协议的存储地址之间的映射关系表；在便携式升级设备中建立源程序数据池，在源程序数据池中存储数个源程序数据，源程序数据用于对待升级设备进行程序升级；每一个源程序数据均分为源程序属性、第一部分升级包和第二部分升级包，源程序数据池分为两个存储区，分别为高位存储区和低位存储区，高位存储区用于存储所有源程序数据的源程序属性和第一部分升级包，低位存储区用于存储所有源程序数据的第二部分升级包；在便携式升级设备中建立密码池，密码池包括密码对照表存储区和密码数据存储区，在密码数据存储区存储数个密码的具体数据以及上一次更换信息，密码的具体数据包括密码本身，上一次更换信息为对密码更换后保留下来的旧密码以及更换时间信息；在密码对照表存储区建立并存储源程序数据的存储地址、源程序数据对应的密码存储地址和源程序对应的协议包地址之间的关系列表；在便携式升级设备中建立一个程序属性查找模块，在程序属性查找模块中建立协议包池、源程序数据池和密码池之间的映射关系列表，并建立源程序检索引擎。
步骤2：便携式升级设备通过编程接口向待升级设备发送一个未加密心跳协议，以 确定是否采用了正确的协议包，如果此时协议包不正确，则待升级设备不会回复任何的心跳协议数据，便携式升级设备显示重新选择协议包的类型及其源程序的信息，提示操作员进行选择后，再执行步骤2；如果正确，则待升级设备会回复心跳协议数据，执行步骤3。
步骤3：便携式升级设备连续三次间隔发送加密心跳协议，判断是否收到正确的加密心跳回复：如果发送加密心跳协议得到了正确的回复，则证明便携式升级设备与待升级设备之间的心跳协议正确，执行步骤4；如果不正确，则证明便携式升级设备与待升级设备之间的心跳协议不正确，所对应的源程序的版本也不正确，此时提示重新选择加密心跳协议包和源程序，并等待操作人员重新选择后，执行步骤2。
由于同一个协议包有可能对应多个不同的心跳加密协议，所以这里需要对心跳加密协议进行确定，进而再确定升级程序的源程序的版本是否选择正确。
步骤4：便携式升级设备确定源程序地址，并向待升级设备传输源程序的第一部分。
本实施例中，协议包池和源程序数据池之间的映射关系为：协议包池中记录了加密心跳协议的地址，而加密心跳协议又记录了源程序属性地址，从而可以准确的找出协议包对应的源程序。
如图2和图3所示，协议包1、协议包2...协议包n即表示了多个协议包，加密心跳协议1、加密心跳协议2...加密心跳协议n即表示了多个加密心跳协议，在存储时，数据结构为：协议包1+相关加密心跳的地址、加密心跳协议1+源程序1属性地址的存储方式。
由于一个协议包有可能对应多个加密心跳协议，则其映射方式为加密心跳协议1对应加密心跳协议1和加密心跳协议2，而加密心跳协议2对应加密心跳协议3和加密心跳协议4，本发明通过此种方式来找出准确的源程序。
步骤5：源程序的第一部分发送完毕后，便携式升级设备发送源程序对应的密码池中的密码；便携式升级设备判断是否收到了待升级设备的正确回复：如果收到了待升级设备的正确回复，则执行步骤6；如果没有收到待升级设备的正确回复，则执行步骤7。
如图4所示为密码池中的数据存储结构，密码池的数据结构分为两个部分，一个用来存储密码的存储地址以及映射的加密心跳协议的地址，一个用来存储密码的数据本身以及相关更新信息。
如：密码1地址+加密心跳协议1地址，即，密码1的存储地址以及映射的加密心跳协议1的存储地址。
密码1+时间信息+上一次更换信息，即密码1的具体数据本身、密码更新的时间信息和上次更新时保留下的旧密码信息。
本发明采用密码唯一的方式，极大的增加了源程序的保密性，且可以将升级工作分成两个部分，增加了工序检查得力度，保证了升级工作的准确。
步骤6：便携式升级设备确定源程序的地址，并向待升级设备传输源程序的第二部分；传完毕后，便携式升级设备提示升级成功，并显示所有升级相关的节点信息，并跳转到步骤10。
如图3所示，本发明的源程序是分为两个部分来存储在源程序数据池中，即，源程序的第一部分和源程序的第二部分，也就是如图3所示的第一部分升级包和第二分升级包，图3中的源程序1、源程序2...源程序n表多个源程序包，为了表示源程序的版本号，本发明 在第一部分升级包前加入了源程序属性，源程序属性包括了版本号。
本发明将升级工序分成了未加密心跳协议节点、加密心跳协议节点、第一部分升级包节点、密码池的密码校验节点和第二部分升级包节点，当升级完成后，在显示屏界面上显示各个节点的相关信息，极大的增强了升级工作的可溯源性，增加了升级工作的准确度。
步骤7：便携式升级设备显示密码错误信息，并显示密码相关的修改信息和现用密码信息，如果没有收到正确的回复，则证明密码池的密码校验失败，此时则显示所使用的密码池中的密码数据以及与其相关的更新信息，更新信息包括密码更新的时间信息和上次更新时保留下的旧密码信息。
步骤8：便携式升级设备等待用户选择，计时器进行计时：如果用户进行了选择，则执行步骤9；如果没有进行选择操作，则在计时完毕后，提示升级失败，并显示错误节点信息，并跳转到步骤10。
步骤9：用户重新选择协议包以及源程序数据。
步骤10：结束。
优选的，未加密心跳协议为：头字节 设备编号 类型 时间戳 校验位 尾字节。
待升级设备回复的未加密心跳协议为：头字节 设备编号 类型 时间戳 校验位 尾字节。
其中设备编号为4个字节，前两个字节为高字，后两个字节为低字，高字表示设备的种类，低字表示设备的具体编号。
在本实施例中，所有待升级设备所采用的协议均包含了心跳协议。
加密心跳协议为：头字节 设备编号 类型 心跳密码 校验位 尾字节。
待升级设备回复的加密心跳协议为：头字节 设备编号 类型 源程序版本号 校验位 尾字节。
其中，心跳密码与密码池中的密码不是同一个密码；源程序版本号是待升级设备中原有的程序的版本号。
本实施例通过加密心跳协议可以很好的确定待升级设备原有的程序是哪一个，并且还可以准确的选择出准备升级的源程序。
优选的，一个协议包对应数个加密心跳协议，每一个加密心跳协议的加密数据均不相同；加密心跳协议是将未加密心跳协议中的时间戳修改成心跳密码数据后，进行打包发送的加密协议包。
优选的，密码池中的密码具有唯一性，且一个密码只对应一个加密心跳协议，密码池中的密码与加密心跳协议中的密码不是同一个密码；密码池的数据结构分为两个部分，第一部分用来存储密码的存储地址以及映射的加密心跳协议的地址，第二部分用来存储密码的数据本身以及相关更新信息。
优选的，在执行步骤4和步骤6时，源程序分为两个部分存储在源程序数据池中，即，源程序的第一部分和源程序的第二部分，在第一部分升级包前加入源程序属性，源程序属性包括版本号。
优选的，在执行步骤7时，如果没有收到正确的回复，则证明密码池的密码校验失败，此时则显示所使用的密码池中的密码数据以及与其相关的更新信息，更新信息包括密码更新的时间信息和上次更新时保留下的旧密码信息。
优选的，在执行步骤8和步骤9时，用户是在便携式升级设备所提供的触摸屏上进行选择。
本实施例中，便携式升级设备包括一个触摸屏、一个主控芯片、编程接口和三个flash存储器，三个flash存储器分别通过不同的IO口与主控芯片通信，编程接口与主控芯片通信，触摸屏通过串口与主控芯片通信。
设定这三个flash存储器分别为flash存储器A、flash存储器B和flash存储器C，协议包池建立在flash存储器A中，flash存储器A被分为两个数据存储区，协议包数据库和加密心跳协议数据库分别存储在这两个数据存储区内。
程序属性查找模块设立在主控芯片中。
所述源程序数据池建立在flash存储器B中，flash存储器B分为两个存储区，源程序数据是分为两个部分存储在flash存储器B的两个存储区中。
所述密码池建立在flash存储器C中，flash存储器C分为两个存储区，一个存储区用来存储密码的存储地址以及映射的加密心跳协议的地址、另一个存储区用来存储密码的数据本身以及相关更新信息。
在本实施例中，由于源程序数据、密码以及协议包的种类较多，需要分成多个flash存储器进行存储，以方便数据调取和交互。
