[32] 所述的计算机电源的开关单元有独立的供电回路, 以提供开关器件开启吋的驱 动电流, 在开关器件关闭吋此供电回路也截止。
[33] 控制单元对于计算机电源和计算机外部设备电源的关闭是依据运行在计算机 系统的数据通信程序从计算机系统中读取的计算机系统电源管理 (Power
Management)数据和 /或者系统日期吋间数据而进行的, 其具体情况如下:
[34] 读取的电源管理 (Power Management)数据包括:
高级配置与电源接口(Advanced Configuration and Power
Interface ACPI)状态、 远程开机设置状态、 定吋开机设置状态、 定吋开机设置吋 间、 外电源供电恢复后开关机设置状态。
[35] 依据高级配置与电源接口 (ACPI)规定的计算机系统处于 S0(正常工作状态)、 S l(POS- Power on Suspend,
CPU关闭其它部件仍正常运作)、 S2(CPU停止运作, 总线吋钟关闭, 其余设备依 然运作)状态吋, 计算机电源指示灯点亮, 此吋计算机及其外部设备电源不可以 被关闭。
[36] 计算机系统处于 S3(STR-Suspend to
RAM,挂起到内存 -系统待机)状态吋, 计算机电源指示灯闪亮, 此吋计算机电源 不可以被关闭, 计算机外部设备电源可以被关闭。
[37] 计算机系统处于 S4(STD-Suspend to Disk,挂起到硬盘-休眠)、 S5(OFF)状态吋, 计算机电源指示灯熄灭, 此吋计算机 及其外部设备电源均可以被关闭。
[38] 但是在处于 S4和 S5状态吋, 如果远程开机设置为开启吋, 计算机电源是不可 以被关闭的, 因为计算机系统随吋准备接收外部开机控制信号, 以开启计算机 系统。
[39] 在处于 S4和 S5状态吋, 如果定吋开机设置为开启吋, 计算机电源可以关闭, 但是本控制模组需要在设定的定吋开机吋间之前开启计算机电源, 以使计算机 系统可以在预定开启吋间开启。 这就需要使用获取的定吋开机设置状态、 定吋 开机设置吋间和系统日期吋间数据来确定计算机电源的开启吋间。 计算机电源 开启吋间较之计算机系统设定开机吋间的提前量应不少于计算机电源开启到完 成预热可稳定供电所需的吋间。 计算机系统定吋开机所依据的吋间是其自身系 统吋间, 计算机电源开启吋间的计算也应依据此吋间数据。
[40] 计算机系统电源管理 (Power
Management)数据的外电源供电恢复后开关机设置状态可以被设置为: 开机 (计算机外电源供电被切断后, 又恢复供电后计算机系统立即开机)、 关机( 计算机外电源供电被切断后, 又恢复供电后计算机系统处于关机状态)、 最后状 态 (计算机外电源供电被切断后, 又恢复供电后计算机系统恢复到外电源供电被 切断吋的状态)。 因为本控制模组控制关闭计算机电源相当于切断计算机外电源 供电, 所以对于计算机系统的开启需要依据此状态设定。 在开启计算机电源后 计算机系统并不是立即处于开机状态的, 就需要通过计算机开关机按键连接单 元或者计算机系统与控制模组的通信单元将开机信号传送给计算机系统。
[41] 对于运行在计算机系统的数据通信程序, 它可以运行在计算机操作系统 (Ope ration System— OS)之下或者运行在计算机基础输出输入系统 (Basic Input Output System_BIOS)之下。 如图 1、 图 2计算机系统的数据通信程序可以从 ACPI Table之中读取由使用者设定的 ACPI电源管理 (Power
Management)数据: 远程开机设置状态、 定吋开机设置状态、 定吋开机设置吋间
、 外电源供电恢复后开关机设置状态; 以及系统运行的 ACPI状态: SO -
S5 ; 从系统吋间函数中读取系统日期 /吋间数据。 并由指定端口将数据通过计算 机系统与控制模组的通信单元传送给控制单元。
[42] 如图 9所示, 运行在计算机系统的数据通信程序是事件触发型程序, 即只有 在特定事件发生吋才会运行。 所指的特定事件是:计算机 ACPI系统状态转变为 S3 、 S4或 S5状态, 或者电源恢复供电, 或者控制单元通过计算机系统与控制模组 的通信单元向运行在计算机系统的数据通信程序发送计算机开机信号。 这些事 件的发生会触发运行在计算机系统的数据通信程序的运行。
[43] 对于与计算机系统与控制模组的通信单元相连接的计算机端口,由于是用来传 送数据的, 因此原则上任何可用于传送数据的计算机端口都是可以的。 运行在 计算机系统的数据通信程序传送数据吋, 只要调用计算机系统中相应端口的驱 动, 如 USB端口驱动及 USB端口。 为了在使用本控制模组过程中, 不影响到计算 机系统其它设备的使用, 也可以釆用非常规数据传送端口的计算机端口, 如计 算机电源指示灯端口, 或者计算机扬声器端口等。 但选用这些端口就需要使用 自定义的通信协议, 因为计算机系统并未为其定义。
[44] 可以选用计算机电源指示灯端口, 是因为其一计算机电源指示灯只是供使用 者观看来分辨计算机系统处于:系统工作、 系统待机还是休眠 /关机, 没有其它功 能; 其二, 通过对计算机电源指示灯的持续点亮、 闪烁还是持续关闭就可以判 断计算机系统吋处于系统工作 SO到 S2、 系统待机 S3还是休眠 /关机 S4/S5; 其三, 因为传送数据量很少、 且只要数据传输速率高于 30bps (高于 25/秒不会被人眼察 觉)就可以, 所以可以构建简单的通信协议。 如图 10所示, 就是一种使用指示灯 端口的简单通信协议示意图; 此通信协议是在指示灯持续关闭吋传送的, 其每 一数据位持续吋间短于 1/30秒, 间隔大于 2/30秒, 使人眼不会察觉。
[45] 如使用计算机扬声器端口, 也可釆用类似协议, 只是以声频输出, 频率只要 低于 10赫兹或高于 20, 000赫兹, 也不会被使用者察觉。
[46] 本发明的贡献在于, 它克服了传统的 AT或者 ATX电源与计算机系统之间缺 乏通信, 在计算机系统不需要电源供电吋无法关闭的缺陷, 在原有电源基础上 增加一个计算机电源待机供电控制模组, 该模组通过在不改变或者不影响现有 计算机标准的情况下使用计算机系统现有端口获取计算机基础输出输入系统 (BI OS)电源管理 (Power Management)数据和 /或者系统日期吋间数据, 在计算机系统或者计算机外部设备 不需要电源供电吋关闭其电源以节约能源。

[58] 具体实施方式
[59] 本发明的计算机电源待机供电控制模组是依据计算机系统 ACPI状态和设定 值, 在计算机系统不需要其电源供电吋关闭其电源, 在计算机系统需要供电吋 幵启其电源的控制模组。
[60] 控制单元 10对于计算机电源和计算机外部设备电源的关闭是依据运行在计算 机系统的数据通信程序从计算机系统中读取的计算机系统电源管理 (Power Management)数据和 /或者系统日期吋间数据而进行的, 其具体情况如下:
[61] 读取的电源管理 (Power Management)数据包括:
高级配置与电源接口(Advanced Configuration and Power
Interface ACPI)状态、 远程幵机设置状态、 定吋幵机设置状态、 定吋幵机设置吋 间、 外电源供电恢复后幵关机设置状态。
[62] 依据高级配置与电源接口 (ACPI)规定的计算机系统处于 S0(正常工作状态)、 S l(POS- Power on Suspend, CPU关闭其它部件仍正常运作)、 S2(CPU停止运作, 总线吋钟关闭, 其余设备依 然运作)状态吋, 计算机电源指示灯点亮, 此吋计算机及其外部设备电源不可以 被关闭。
[63] 计算机系统处于 S3(STR-Suspend to
RAM,挂起到内存 -系统待机)状态吋, 计算机电源指示灯闪亮, 此吋计算机电源 不可以被关闭, 计算机外部设备电源可以被关闭。
[64] 计算机系统处于 S4(STD-Suspend to
Disk,挂起到硬盘-休眠)、 S5(OFF)状态吋, 计算机电源指示灯熄灭, 此吋计算机 及其外部设备电源均可以被关闭。
[65] 但是在处于 S4和 S5状态吋, 如果远程幵机设置为幵启吋, 计算机电源是不可 以被关闭的, 因为计算机系统随吋准备接收外部幵机控制信号, 以幵启计算机 系统。
[66] 在处于 S4和 S5状态吋, 如果定吋幵机设置为幵启吋, 计算机电源可以关闭, 但是本控制模组需要在设定的定吋幵机吋间之前幵启计算机电源, 以使计算机 系统可以在预定幵启吋间幵启。 这就需要使用获取的定吋幵机设置状态、 定吋 幵机设置吋间和系统日期吋间数据来确定计算机电源的幵启吋间。 计算机电源 幵启吋间较之计算机系统设定幵机吋间的提前量应不少于计算机电源幵启到完 成预热可稳定供电所需的吋间。 计算机系统定吋幵机所依据的吋间是其自身系 统吋间, 计算机电源幵启吋间的计算也应依据此吋间数据。
[67] 计算机系统电源管理 (Power
Management)数据的外电源供电恢复后幵关机设置状态可以被设置为: 幵机 (计算机外电源供电被切断后, 又恢复供电后计算机系统立即幵机)、 关机( 计算机外电源供电被切断后, 又恢复供电后计算机系统处于关机状态)、 最后状 态 (计算机外电源供电被切断后, 又恢复供电后计算机系统恢复到外电源供电被 切断吋的状态)。 因为本控制模组控制关闭计算机电源相当于切断计算机外电源 供电, 所以对于计算机系统的幵启需要依据此状态设定。 在幵启计算机电源后 计算机系统并不是立即处于幵机状态的, 就需要通过计算机幵关机按键连接单 元或者计算机系统与控制模组的通信单元将幵机信号传送给计算机系统。 [68] 运行在计算机系统的数据通信程序 110, 它可以是运行在计算机操作系统 (Op eration System_OS)之下或者是运行在计算机基础输出输入系统 (Basic Input Output
System_BIOS)之下。 如图 9所示计算机系统的数据通信程序 110是一种事件触发 型程序, 该程序的启动是由一些特定的事件触发的: 计算机 ACPI系统状态转变 为 S3、 S4或 S5状态, 或者电源恢复供电, 或者控制单元通过计算机系统与控制 模组的通信单元向运行在计算机系统的数据通信程序发送计算机幵机信号。 计 算机系统的数据通信程序 110启动后会首先读取 ACPI电源管理数据和日期 /吋间 数据。 如图 1、 图 2计算机系统的数据通信程序 110从计算机系统的 ACPI
Table之中读取由使用者设定的 ACPI电源管理数据包括: 远程幵机设置状态、 定 吋幵机设置状态、 定吋幵机设置吋间、 外电源供电恢复后幵关机设置状态; 以 及系统运行的 ACPI状态: SO -
S5; 从计算机系统吋间函数中读取系统日期 /吋间数据。 计算机系统的数据通信 程序 110在完成数据读取后会通过选定的与控制模组的通信单元 20所连接的计算 机端口 80将读取的数据通过计算机系统与控制模组的通信单元 20传送给控制单 元 10。 在完成数据传送后, 数据通信程序 110会停止运行, 等待下一次事件触发 启动。
[69] 当控制单元 10通过计算机系统与控制模组的通信单元 20向运行在计算机系统 的数据通信程序 110发送计算机幵机信号触发启动吋, 数据通信程序 110会通过 选定的与控制模组的通信单元 20所连接的计算机端口 80读取由通信单元 20发送 的幵机信号, 并通知计算机系统以幵启计算机。 在完成传送幵机信号后, 数据 通信程序 110会停止运行, 等待下一次事件触发启动。
[70] 对于与计算机系统与控制模组的通信单元 10相连接的计算机端口 80,由于是用 来传送数据的, 因此原则上任何可用于传送数据的计算机端口都是可以的。 运 行在计算机系统的数据通信程序 110传送数据吋, 只要调用计算机系统中相应端 口的驱动, 如 USB端口驱动及 USB端口。 为了在使用本控制模组过程中, 不影响 到计算机系统其它设备的使用, 也可以釆用非常规数据传送端口的计算机端口 , 如计算机电源指示灯端口, 或者计算机扬声器端口等。 但选用这些端口就需 要使用自定义的通信协议, 因为计算机系统并未为其定义。 如图 10所示句是一 种自定义的通信协议示例。
[71] 可以选用计算机电源指示灯端口, 是因为其一计算机电源指示灯只是供使用 者观看来分辨计算机系统处于:系统工作、 系统待机还是休眠 /关机, 没有其它功 能; 其二, 通过对计算机电源指示灯的持续点亮、 闪烁还是持续关闭就可以判 断计算机系统吋处于系统工作 SO到 S2、 系统待机 S3还是休眠 /关机 S4/S5; 其三, 因为传送数据量很少、 且只要数据传输速率高于 30bps (高于 25/秒不会被人眼察 觉)就可以, 所以可以构建简单的通信协议。 如图 10所示, 就是一种使用指示灯 端口的简单通信协议示意图; 此通信协议是在指示灯持续关闭吋传送的, 其每 一数据位持续吋间短于 1/30秒, 间隔大于 2/30秒, 使人眼不会察觉。
[72] 如使用计算机扬声器端口, 也可釆用类似协议, 只是以声频输出, 频率只要 低于 10赫兹或高于 20, 000赫兹, 也不会被使用者察觉。
[73] 图 3、 图 4所示, 是一种选用计算机电源指示灯端口 81作为计算机系统与控制 模组通信单元 20相连接计算机端口 80的实施方案。 对于计算机电源指示灯端口 8 1输出的检测, 通过如图 7所示串联在计算机电源指示灯 61与计算机电源指示灯 端口 81回路的光电耦合器件 21予以实现;
当计算机电源指示灯端口 81有输出吋, 计算机电源指示灯 61回路中的电流通过 串联的光电耦合器件 21, 经光电耦合器件 21将计算机电源指示灯端口 81的输出 信号传送给控制单元 10。 也可以釆用并联在计算机电源指示灯 61与计算机电源 指示灯端口 81回路的光电耦合器件 21予以实现; 当计算机电源指示灯端口 81有 输出吋, 其输出电平通过并联的光电耦合器件 21将计算机电源指示灯端口 81的 输出信号传送给控制单元 10。
[74] 如图 3和图 7所示计算机电源指示灯 61与计算机电源指示灯端口 81相连接的情 况, 此吋计算机电源指示灯 61由计算机直接点亮。 如图 4所示计算机电源指示灯 61与计算机电源指示灯端口 81不相连接的情况, 计算机系统与控制模组通信单 元 20分别与计算机电源指示灯 61与计算机电源指示灯端口 81相连接; 控制单元 1 0通过与计算机电源指示灯端口 81相连接的计算机系统与控制模组通信单元 20获 得计算机电源指示灯 61点亮信号, 计算机电源指示灯 61由控制单元 10通过计算 机系统与控制模组通信单元 20点亮。
[75] 如图 3、 图 4所示, 所示在计算机系统进入系统待机、 系统休眠 /关机状态吋, 控制单元 10通过计算机系统与控制模组通信单元 20获取计算机系统的电源管理 数据、 系统日期吋间数据。 电源管理数据包括:远程开机设置状态、 定吋开机设 置状态、 定吋开机设置吋间、 外电源供电恢复后开关机设置状态、 高级配置与 电源接口 (ACPI)状态。 控制单元 10依据所获得数据, 控制计算机电源的开关单元 40对计算机电源 90进行如下操作:
[76] 当计算机系统处于 ACPI的系统待机 S3状态吋, 不关闭计算机电源 90; 在计 算机电源的开关单元 40具有对外部设备电源开启 /关闭功能吋, 此状态下可以关 闭外部设备电源。
[77] 当计算机系统处于 ACPI的系统休眠 S4或者关机 S5状态吋, 远程开机设置为 关闭吋, 关闭计算机电源 90; 在计算机电源的开关单元 40具有对外部设备电源 开启 /关闭功能吋, 此状态下可以关闭外部设备电源。
[78] 当计算机系统处于 ACPI的系统休眠 S4或者关机 S5状态吋, 远程开机设置为 开启吋, 不关闭计算机电源 90; 在计算机电源的开关单元 40具有对外部设备电 源开启 /关闭功能吋, 此状态下可以关闭外部设备电源。
[79] 在计算机电源 90关闭状态下, 定吋开机设置为开启吋, 控制单元 10使用获取 的定吋开机设置状态、 定吋开机设置吋间和系统日期吋间数据来确定计算机电 源的开启吋间, 在预定的开启吋开启计算机电源 90。 计算机电源开启吋间较之 计算机系统设定开机吋间的提前量应不少于计算机电源开启到完成预热可稳定 供电所需的吋间。 计算机系统定吋开机所依据的吋间是其自身系统吋间, 计算 机电源开启吋间的计算也应依据此吋间数据。
[80] 如图 3、 图 4所示, 在计算机电源 90关闭状态下,
控制单元 10通过计算机开关机按键连接单元 30检测计算机开关机按键 71是否被 按下, 当计算机开关机按键 71被按下则可判定计算机需要开机。 控制单元 10通 过计算机电源的开关单元 40开启计算机电源 90。 当计算机系统电源管理 (Power Management)的外电源供电恢复后开关机设置为需要按开关机按键开机吋, 在计 算机电源开启及预热后, 控制单元 10通过计算机开关机按键连接单元 30将计算 机开关机按键的按键开机信号传送给计算机开关机按键端口 72, 以开启计算机 系统。 如图 6所示, 计算机电源的开关单元 40与计算机开关机按键端口 72不相连 接吋, 控制单元 10将计算机开关机按键 71的按键开机信号通过计算机系统与控 制模组的通信单元 20传送给运行在计算机系统的数据通信程序, 再由运行在计 算机系统的数据通信程序将计算机开关机按键的按键开机信号传送给计算机系 统, 以开启计算机系统。
[81] 计算机系统电源管理数据的外电源供电恢复后开关机设置状态可以被设置为
:开机 (计算机外电源供电被切断后, 又恢复供电后计算机系统立即开机)、 关机 ( 计算机外电源供电被切断后, 又恢复供电后计算机系统处于关机状态)、 最后状 态 (计算机外电源供电被切断后, 又恢复供电后计算机系统恢复到外电源供电被 切断吋的状态)。 因为本控制模组控制关闭计算机电源相当于切断计算机外电源 供电, 所以对于计算机系统的开启需要依据此状态设定。 在开启计算机电源后 计算机系统并不是立即处于开机状态的, 就需要通过计算机开关机按键连接单 元或者计算机系统与控制模组的通信单元将开机信号传送给计算机系统。
[82] 对于计算机电源开机预热吋间, 需根据具体应用的计算机电源而定, 每种计 算机电源有其相对固定的预热吋间, 一般在 3至 5秒之间。 另外, 也可以通过探 测计算机 ATX电源的 Power
Ready脚, 来确定计算机电源是否完成预热。 等待计算机电源开机预热吋间, 是 因为在计算机电源未完成预热吋, 其对计算机的供电是不稳定的, 计算机也未 进入稳定工作状态; 如果此吋通过计算机开关机按键连接单元 30将计算机开机 信号传送给计算机开关机按键端口 72, 计算机系统可能无法正确接收而使计算 机系统不会开启。
[83] 对于计算机开关机按键 71是否被按下的检测可以通过检测计算机开关机按键
71回路是否导通予以实现。 因为对计算机开关机按键 71是否被按下的检测是在 计算机系统关机, 且其电源 90已被计算机电源的开关单元 40关闭没有供电的情 况下进行的, 因此可以使用一个如图 7所示与计算机开关机按键 71两端连接的电 容电路 31来实现。 电容电路 31由控制单元 10提供脉冲信号, 当计算机开关机按 键 71被按下吋电容电路 31导通, 控制单元 10接收到返回的供脉冲信号, 从而得 以判断。
[84] 对于计算机开关机按键端口 72的计算机开机信号传送通过如图 7所示的与计 算机开关机按键端口 72并联的光电耦合器件 32实现。 在传送信号吋, 控制单元 1 0将计算机开机信号高电平传送给光电耦合器件 32, 光电耦合器件 32在计算机开 关机按键端口 72回路中产生电流, 信号得以传送。
[85] 图 3所示, 计算机开关机按键 71与计算机开关机按键端口 72相连接。
[86] 图 4和图 7所示, 计算机开关机按键 71与计算机开关机按键端口 72不相连接, 在计算机处于开机状态下计算机开关机按键 71被按下的信号传送给控制芯片 11 , 控制芯片 11通过与计算机开关机按键端口 72并联的光电耦合器将按键信号传 送给计算机开关机按键端口 72。
[87] 如图 6所示, 计算机电源的开关单元 40与计算机开关机按键端口 72不相连接 吋, 控制单元 10将计算机开关机按键 71的按键信号通过计算机系统与控制模组 的通信单元 20传送给运行在计算机系统的数据通信程序, 再由运行在计算机系 统的数据通信程序将计算机开关机按键的按键信号传送给计算机系统。
[88] 如图 7、 图 8所示, 计算机电源的开关单元 40, 是由控制单元 10控制开关计算 机电源 90的, 是由开关器件及其驱动电路构成的。 对计算机电源 90的开关可以 通过导通或截止计算机电源的外部电源输入回路 91 ; 或者通过导通或截止计算 机电源整流后的直流回路 92; 或者通过导通或截止计算机电源滤波后直流回路 9 3; 或者通过导通或截止计算机电源控制芯片的供电回路 94来实现开启或关闭计 算机电源 90。
[89] 计算机电源的开关单元 40使用的开关器件可以是继电器、 可控硅、 晶体开关 器件或者单向晶体开关器件和桥式整流电路。
[90] 如图 7所示, 为降低本控制电路在计算机处于关机状态下的自身功耗, 计算 机电源的开关单元 40可以有独立的供电回路 41, 以提供开关器件开启吋的驱动 电流, 在开关器件关闭吋此供电回路也截止。
[91] 如前述各单元所用器件均可釆用常规器件。
[92] 尽管通过以上实施例对本发明进行了揭示, 但是本发明的范围并不局限于此
, 在不偏离本发明构思的条件下, 以上各构件可用所属技术领域人员了解的相 似或等同元件来替换。
