具体实施方式
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。
本发明提供了一种基于Linux或Unix内核操作系统的串口映射方法及装置，用于自动生成物理串口与逻辑串口的映射关系，实现串口的自动识别和匹配，以下分别进行详细描述。
请参阅图1，图1是本发明实施例提供的基于Linux或Unix内核操作系统的串口映射方法的流程示意图。所述串口映射方法可由基于Linux或Unix内核操作系统的串口映射装置(以下称为串口映射装置)来执行，并至少包括如下步骤：
S101，从基本输入输出系统(BIOS)获取第一串口列表；其中，所述第一串口列表存储了面板的至少一个物理串口的串口信息。
请一并参阅图2，具体的，在本发明实施例中，所述串口映射装置可通过在用户层调用中断指令，并将所述中断指令发送给所述基本输入输出系统(Basic Input Output System，BIOS)，所述BIOS在接收到所述中断指令后，向所述串口映射装置返回第一串口列表，其中，所述第一串口列表内按顺序存储了面板的所有物理串口及每个物理串口的串口信息，所述物理串口的串口信息可包括收发器类型、中断号及端口地址。
S102，从基于Linux或Unix内核的操作系统获取第二串口列表；其中，所述第二串口列表存储了所述操作系统的至少一个逻辑串口的串口信息。
请一并参阅图3，具体地，在本发明实施例中，所述串口映射装置在操作系统的用户层输入特定指令读取第二串口列表，其中，所述第二串口列表存储了所述操作系统的所有逻辑串口的串口信息，同样的，所述逻辑串口的串口信息可包括收发器类型、中断号及端口地址。
在本发明实施例中，所述操作系统可为Linux系统，则一般地，所述特定指令可为/proe/tty/driver/serial。然而应当理解的是，在本发明的其他实施例中，所述操作系统还可为其他操作系统，如UNIX系统等，具体的指令也可根据实际的系统配置进行指定，本发明不做具体限定。
S103，根据所述串口信息对所述第一串口列表的物理串口和第二串口列表中的逻辑串口进行匹配，生成所述第一串口列表与所述第二串口列表的串口映射文件，以使所述操作系统在检测到外部设备接入时，根据所述串口映射文件及所述外部设备当前接入的物理串口获取映射的逻辑串口，并根据与所述逻辑串口对应的程序与所述外部设备进行通信。
在本发明实施例中，所述串口映射装置在获得所述第一串口列表和第二串口列表后，根据所述串口信息对所述第一串口列表的物理串口和第二串口列表中的逻辑串口进行匹配，并根据匹配的结果生成所述第一串口列表与所述第二串口列表的串口映射文件。
请一并参阅图4，具体地，可包括如下步骤：
S1031，获取为所述第一串口列表配置的第一指针当前指向的物理串口的串口信息。
在本发明实施例中，所述串口映射装置可定义一个第一指针，所述第一指针用于指向所述第一串口列表内的物理串口，并可在所述第一串口列表内移动，以指向不同的物理串口，其中，所述第一指针指向一个物理串口时，所述串口映射装置将获取该物理串口的串口信息。
S1032，获取为所述第二串口列表配置的第二指针当前指向的逻辑串口的串口信息。
在本发明实施例中，同样的，所述串口映射装置还可定义一个第二指针，所述第二指针用于指向所述第二串口列表内的逻辑串口，并可在所述第二串口列表内移动，以指向不同的逻辑串口，其中，所述第二指针指向一个逻辑串口时，所述串口映射装置将获取该逻辑串口的串口信息。
S1033，根据所述第一指针当前指向的物理串口的串口信息及所述第二指针当前指向的逻辑串口的串口信息，判断所述物理串口与所述逻辑串口是否匹配。
在一个实施例中，所述串口映射装置可判断第一指针当前指向的物理串口的串口信息及所述第二指针当前指向的逻辑串口的串口信息是否完成一致，例如，依次判断所述物理串口的收发器类型、中断号及端口地址是否与所述逻辑串口的收发器类型、中断号及端口地址一致，若全部一致，则所述物理串口与所述逻辑串口匹配，而只要有一个串口信息不一致，则所述物理串口与所述逻辑串口不匹配。
在另一个实施例中，也可先根据哈希算法和所述串口信息生成一个哈希值，再判断哈希值是否一致来判断所述物理串口与所述逻辑串口是否匹配，由于哈希算法的特性，只有当收发器类型、中断号及端口地址完全一致，得出的哈希值才一致。具体地：
首先，根据哈希算法及所述第一指针当前指向的物理串口的串口信息生成第一哈希值。
然后，根据哈希算法及所述第二指针当前指向的逻辑串口的串口信息生成第二哈希值。
最后，根据所述第一哈希值及所述第二哈希值判断所述物理串口与所述逻辑串口是否匹配。
如此，相比于直接对串口信息进行匹配，简化了匹配的过程，并提高了匹配的可靠性
S1034，若否，则在确定所述第二指针当前指向的逻辑串口不位于所述第二串口列表的列表末尾时，控制所述第二指针移动到位于当前指向的所述逻辑串口之后的下一个逻辑串口。
在本发明实施例中，若所述物理串口与所述逻辑串口不匹配，则所述串口映射装置先确定所述第二指针当前指向的逻辑串口是否位于所述第二串口列表的列表末尾(当所述第二指针向后移动一步后指向NULL时，则代表已经到了所述第二串口列表的列表末尾)，如果是，则控制所述第一指针移动到位于当前指向的所述物理串口之后的下一个物理串口，并控制所 述第二指针指向所述第二串口列表内的第一个逻辑串口。若否，则所述串口映射装置控制所述第二指针移动到位于当前指向的所述逻辑串口之后的下一个逻辑串口。
S1035，若是，则记录所述物理串口与所述逻辑串口的映射关系，并判断所述第一指针当前指向的物理串口是否位于所述第一串口列表的列表末尾。
在本发明实施例中，若所述物理串口与所述逻辑串口匹配，则所述串口映射装置记录所述物理串口与所述逻辑串口的映射关系，如记录所述物理串口的序号及所述逻辑串口的路径形成的映射关系，例如，映射关系可记录为：物理串口1映射为/dev/COM1，其表示面板上的序号为1的物理串口与操作系统的/dev/COM1的逻辑串口匹配。
在本发明实施例中，在记录所述映射关系后，所述串口映射装置还判断所述第一指针当前指向的物理串口是否位于所述第一串口列表的列表末尾(当所述第一指针向后移动一步后指向NULL时，则代表已经到了所述第一串口列表的列表末尾)。
S1036，若否，则控制所述第一指针移动到位于当前指向的所述物理串口之后的下一个物理串口，并在所述第二串口列表中删除所述第二指针当前指向的逻辑串口后，控制所述第二指针指向所述第二串口列表内的第一个逻辑串口。
在本发明实施例中，若所述串口映射装置判断所述第一指针当前指向的物理串口不是位于所述第一串口列表的列表末尾，则说明所述第一串口列表内尚有物理串口未经过匹配，此时，所述串口映射装置控制所述第一指针移动到位于当前指向的所述物理串口之后的下一个物理串口，并在所述第二串口列表中删除所述第二指针当前指向的逻辑串口后，控制所述第二指针指向所述第二串口列表内的第一个逻辑串口。
S1037，若是，则根据所有已记录的映射关系，生成所述第一串口列表与所述第二串口列表的串口映射文件。
在本发明实施例中，若所述串口映射装置判断所述第一指针当前指向的物理串口位于所述第一串口列表的列表末尾，则说明所述第一串口列表内的所有物理串口均经过匹配，此时，所述串口映射装置根据所有已记录的映射关系，生成所述第一串口列表与所述第二串口列表的串口映射文件。所述串口映射文件为所有物理串口与逻辑串口的映射关系的汇总文件，如此，当有外部设备接入面板上的物理串口时，即可根据所述串口映射文件找到对应的逻辑串口，再根据所述逻辑串口找到对应的程序来实现与所述外部设备进行通信。
综上所述，本发明实施例提供的串口映射方法，通过对从BIOS获取的第一串口列表内的物理串口和从操作系统下获取的第二串联列表内的逻辑串口进行自动匹配，从而在不需要人为干涉的情况下自动生成描述物理串口与逻辑串口映射关系的串口映射文件，提高了识别匹配的效率和准确率。此外，由于不需要专门的外部设备和辅助软件，还同时减低了成本。
