为使本发明解决的技术问题、 采用的技术方案和达到的技术效果更加清楚， 下面将结合附图对本发明实施例的技术方案作进一歩的详细描述， 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， 本领域技术人员在没有作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所示， 为本发明实施例 1提供的键盘按键编码同时上传的方法的流 程示意图；
提供一种键盘按键编码同时上传的方法， 包括如下歩骤：
S101、 将键盘和主机之间的 USB数据传输通道枚举为具有传输标准按键编 码功能的标准按键指令接口和具有传输非标准按键编码功能的非标准按键指令 接口； 根据 USB规范中 USB键盘应用方法， 将键盘和主机之间的 USB数据传输通 道抽象成一个具有传输标准按键编码功能的标准按键指令接口和一个具有传输 非标准按键编码功能的非标准按键指令接口。 所述 USB数据传输通道指： 键盘 侧 USB驱动、 键盘的 USB端点、 主机的 USB端点、 以及两个 USB端点之间的包 括 USB数据线在内的数据传输通道。
所述枚举过程具体为： 首先， 键盘侧将传输数据的键盘 USB端点定义为一 个键盘 USB接口， 并将键盘 USB端点通过 USB数据线连接到主机的 USB端点， 之后， 主机向键盘发送请求， 请求获得所连接的键盘 USB接口的键盘信息； 键 盘在收到请求后， 向主机发送所请求的键盘信息， 然后， 主机在获得这些信息 并根据此信息确定能够提供的键盘 USB驱动，加载相应符合 USB规范的键盘 USB 驱动； 最终， 主机在得到包括 HID报告描述符的键盘信息之后， 认为所连接的 键盘 USB接口的信息已经齐全， 便由键盘 USB驱动对键盘进行配置， 配置成功 即可实现键盘与主机之间的数据传输。 至此， 枚举过程结束。 经过 2 次类似的 枚举过程就可实现将键盘和主机之间的 USB数据传输通道枚举为具有传输标准 按键编码功能的标准按键指令接口和具有传输非标准按键编码功能的非标准按 键指令接口。
键盘信息中包括键盘的 HID报告描述符， HID报告描述符是当设备被定义为 一个 HID设备时才需要的描述符， 这个描述符表明这个设备支持 USB协议的版 本号， 是否有专有描述符， 对描述符的特征限定， 以及定义的主机和设备之间 通信时数据的组织方式。 本实施例的标准按键指令接口采用标准 HID报告描述 符， 非标准按键指令接口采用非标准 HID报告描述符。
所述的标准 HID报告描述符为通用的键盘报告描述符， 前几项举例如下： Item Tag(Value) Raw Date Usage Page (Generic Desktop) 05 01
Usage (Keyboard) 09 06
Collection (Application) Al 01
Usage Page (Keyboard/ Keybad) 05 07
Usage Minimum (Keyboard Left Control) 19 E0
Usage Maximum (Keyboard Right GUI) 29 E7
Logical Minimum(O) 15 00
Logical Maximum(l) 25 01
Report Size(l) 75 01
Report Count(8) 95 08
Input (Data, Var,Abs,NVVrp,Lin,Pref,丽 ul,Bit) 81 02 上面这几项描述了一个输入用的字段， 总共为 8个 bits, 每个 bit表示一 个按键分别从左 ctrl键到右 GUI键。 这 8个 bits刚好构成一个字节， 它位于 报告的第一个字节。 它的最低位， 即 bit-0对应着左 ctrl键， 如果返回的数据 该位为 1， 则表示左 ctrl键被按下， 否则， 左 ctrl键没有按下。 它的最高位， 即 bit-7表示右 GUI键的按下情况。 中间的几个位， 需要根据 HID协议中规定 的用途页表 （HID Usage Tables) 来确定。 通常用来表示特殊键， 例如 ctrl , shift , del键等
非标准按键指令接口采用的非标准 HID报告描述符， 为不通用的键盘报告 描述符， 根据非标准 BIOS环境中不同的 BIOS程序有所不同。 前几项举例如下： Item Tag(Value) Raw Date
Usage (Keyboard) 09 06 Collection (Application) Al 01
Report ID (2) 85 02
Usage Page (Keyboard/ Keybad) 05 07
Usage Minimum (Keyboard a and A) 19 04
Usage Maximum (Keyboard Application) 29 65
Logical Minimum(O) 15 00
Logical Maximum(l) 25 01
Report Size(l) 75 01
Report Count(98) 95 62
Input (Data, Var,Abs,NVVrp,Lin,Pref,丽 ul,Bit) 81 02
5102、 通过键盘同时获得小于等于标准按键个数阈值的标准按键指令， 解 析所述标准按键指令并从预设标准按键编码集合中提取相应的待执行标准按键 编码，通过标准按键指令接口上传所述待执行标准按键编码至主机；
同时获得小于等于标准按键个数阈值的指令为标准按键指令， 标准按键指 令接口为标准 HID键盘接口，能够在所有兼容 USB HID键盘的 BIOS环境下使用。 标准按键指令接口的 HID报告描述符使用通用的键盘报告描述符。
5103、 通过键盘同时获得大于等于非标准按键个数阈值的非标准按键指令， 解析所述非标准按键指令并从预设非标准按键编码集合中提取相应的待执行非 标准按键编码，通过非标准按键指令接口上传所述待执行非标准按键编码至主 机。
同时获得大于等于非标准按键个数阈值的指令为非标准按键指令， 非标准 按键指令接口为非标准 HID键盘接口， 能够在所有兼容非标准的 USB HID键盘 的 BIOS环境下使用。 非标准按键指令接口的 HID报告描述符使用非标准的键盘 报告描述符。 本实施例中非标准按键指令为大于等于非标准按键个数阈值的指 令， 非标准按键指令可为全键盘按键个数的指令。
一种键盘按键编码同时上传的方法， 键盘的 USB设备分别枚举用于上传通 过键盘同时获得小于等于标准按键个数阈值的标准按键指令和用于上传通过键 盘同时获得大于等于非标准按键个数阈值的非标准按键指令，当用户同时通过 键盘进行若干个按键指令输入时， 标准按键指令接口和非标准按键指令接口分 别在键盘和主机之间的 USB数据传输通道中传输信息， 两个动作同时进行， 实 现在兼容标准和非标准的 BIOS环境下， 全键盘按键编码同时上传， 不产生键盘 按键冲突现象。
BIOS ( Basic Input Output System, 基本输入输出系统） 〃是一组固化到 计算机内主板 ROM芯片上的程序， 是计算机保存的最重要的基本输入输出程序、 系统设置信息、 开机后自检程序和系统自启动程序。 其主要功能是为计算机提 供最底层的、 最直接的硬件设置和控制。
计算机上使用的 BIOS程序根据制造厂商的不同分为： AWARD BIOS程序、 AMI BIOS程序、 PHOENIX BIOS程序以及其它的免跳线 BIOS程序和品牌机特有的 BIOS 程序， 如 IBM等。 目前标准主板 BIOS有三大类型， 即 AWARD、 AMI和 PH0ENIX。 不过， PHOENIX 已经合并了 AWARD , 因此在台式机主板方面， 其虽然标有 AWARD-PHOENIX, 其实际还是 AWARD的 BI0S。 PHOENIX BIOS 多用于高档的 586 原装品牌机和笔记本电脑上，其画面简洁，便于操作。除了三大类型的主板 BIOS 程序是标准 BIOS环境， 其他的 BIOS程序都属于非标准 BIOS环境。
如图 2所示， 为本发明实施例 2提供的键盘按键编码同时上传的方法的流 程示意图； 本实施例增加了预设标准按键编码集合、 预设非标准按键编码集合、 设置标准按键个数阈值和设置非标准按键个数阈值歩骤。
提供一种键盘按键编码同时上传的方法， 包括如下歩骤：
S201、 建立并存储标准按键指令和标准按键编码信息对应的预设标准按键 编码集合； 建立并存储非标准按键指令和非标准按键编码信息对应的预设非标 准按键编码集合。
标准按键编码信息为若干个小于等于标准按键个数阈值的按键指令， 包括 每个按键的编码信息和若干个按键的组合序列； 非标准按键编码信息为若干个 大于等于非标准按键个数阈值的按键指令， 包括每个按键的编码信息和若干个 按键的组合序列。
键盘分为编码键盘和非编码键盘。 编码键盘主要依靠一块专用的大规模集 成电路完成扫描、 编码、 传送功能。 一个完整的键盘控制电路由键位矩阵、 时 钟发生器及主 IC组成。 键位矩阵制作在电路板上， 时钟发生器用来产生一系列 有规律的脉冲， 它决定主 IC扫描键位矩阵的频率， 键盘控制电路的一切工作歩 骤都要按时钟发生器送来的节律进行。 主 IC按照时钟发生器送来的不间断的脉 冲频率， 向键位矩阵的行或列， 逐行或列送出扫描信号； 当某个键被按下以后， 相应的扫描信号就会被与之交叉的行或列方向的检测电路所发现而产生交连信 号， 该交连信号决定了该键的坐标位置； 交连信号送入主 ic， 经过其内部编码 电路后便产生该键的编码信息， 如 ASCI I码。
非编码键盘不直接提供按键的编码信息， 而是采用较为简单的硬件和一套 专用程序来识别按键的位置。 非编码键盘利用软件驱动下的硬件来完成诸如扫 描、 编码、 传送功能， 这个程序被称之为键盘处理程序。 整个键盘处理程序由 查询程序、 传送程序、 译码程序三部分组成。 主程序首先调用查询程序， 通过 查询接口逐行扫描键位矩阵， 同时检测行列的输出， 由行与列的交连信号确定 某闭合键的坐标， 即得到被按键对应的扫描码； 主程序调用传送程序将得到的 扫描码传送给位于主机内的键盘接口电路； 主程序调用译码程序将键盘接口内 的扫描码翻译为相应键的编码信息。
5202、 设置标准按键个数阈值和非标准按键个数阈值。
优选的，所述标准按键个数阈值为 6， 所述非标准按键个数阈值为 7。 当然， 所述标准按键个数阈值也可以为 12 或 24， 对应的所述非标准按键个数阈值为 13或 25 ο
5203、 将键盘和主机之间的 USB数据传输通道枚举为具有传输标准按键编 码功能的标准按键指令接口和具有传输非标准按键编码功能的非标准按键指令 接口；
一般的 USB设备都需要一个 "驱动程序" ， 该驱动程序提供了从应用软件 到 USB设备的数据传输通道， 但驱动程序编写技术复杂， 一旦出错直接导致系 统死机。为此，操作系统对一些典型的 USB设备例如 HID设备（Human Interface Device, 人机接口设备， 是指直接和人进行互动的设备， 如鼠标、 键盘等） 提 供了内置的驱动程序， USB HID设备连接到主机后，会把一系列数据发送到主机， 这一系列数据表明设备的类型以及所能支持的数据传输方式， 这些数据即为描 述符。 描述符是数据结果或是信息的格式化块， 它可以使主机知道这个设备。 每个描述符包含了关于这个设备整体信息或者一个元素信息。 所有的 USB外设 必须响应对标准 USB HID报告描述符的请求。 在枚举过程中主机使用控制传输 来从设备请求 HID报告描述符。
5204、 通过键盘同时获得小于等于标准按键个数阈值的标准按键指令， 解 析所述标准按键指令并从预设标准按键编码集合中提取相应的待执行标准按键 编码，通过标准按键指令接口上传所述待执行标准按键编码至主机； S205、 通过键盘同时获得大于等于非标准按键个数阈值的非标准按键指令， 解析所述非标准按键指令并从预设非标准按键编码集合中提取相应的待执行非 标准按键编码，通过非标准按键指令接口上传所述待执行非标准按键编码至主 机。
本实施例涉及的键盘能够在兼容标准或非标准的 BIOS环境下同时向 PC系 统上传全部按键键值， 实现所有按键同时按下而不产生键盘按键冲突现象的功 能， 同时还能够在不同的标准或非标准的 BIOS环境下使用， 同时向 PC系统上 传多个按键键值。
