具体实施方式
在图 2中, 主控制器 1采用内置方式, 电脑机内的主控制器 1的继电器控制端口 KR- OUT 通过挡板式连接器 2与电脑机外的受控电源插座 3相连接, 挡板式连接器 2为控制装置提供 贯通电脑主机内外部的电气连接通道。 目前,普通台式电脑主机内部留置了 3. 5/5. 25英寸驱 动器托架和 PCI/PCI- E扩展槽(PCI/PCI-E是电脑的局部总线规范), 因此主控制器 1的外形 结构可以采用与 3. 5/5. 25 英寸驱动器外形相同或类似的模块形式, 安装于电脑机箱的 3. 5/5. 25英寸驱动器托架, 主电源输入包括电路的接地可使用主机电源盒空闲的主电源输出 插头或其它端口, 或者主控制器 1的外形结构也可以采用 PCI/PCI E板卡形式, 安装于电脑 主板的 PCI/PCI- E扩展槽,主电源输入包括电路接地可由电脑主板的 PCI/PCI-E扩展槽提供, 并且挡板式连接器 2可与主控制器 1合为一体, 此类结构符合电脑硬件结构规范, 使控制装 置的安装过程较为简单; 电脑机箱内空间较大, 因此主控制器 1的外形结构也可以采用非标 准结构的模块形式; 或者主控制器 1也可以集成于电脑机箱, 与电脑机箱一体化或制成电脑 机箱的附件。
在图 3中, 主控制器 1采用外置方式, 电脑主机 5的主机电源开关 P- SW、 主电源输出端 口 DC-0UT、 主板电源开关输入端口 P-SW+/-通过挡板式连接器 2与电脑主机 5外部的主控制 器 1相连接, 挡板式连接器 2为控制装置提供贯通电脑主机内外部的电气连接通道。 在主控 制器 1采用外置方式时, 主控制器 1和受控电源插座 3可以合并为一体结构, 以增强其整体 性, 或者主控制器 1和受控电源插座 3合并后减少其输出用单体插座数量, 使其成为一个单 控制器, 与普通多位电源插座配合使用。
在图 4所示实施例中:
©图 4所示实施例的构成与连接:主控制器 1采用内置方式,主控制器 1采用与 3. 5英 寸驱动器外形相同或类似的模块 /组件形式,安装在电脑机箱一个空闲的 3. 5英寸驱动器托架 上, 电池安装于主控制器 1内部, 挡板式连接器 2安装于电脑机箱后部一个空闲的扩展槽挡 板位, 受控电源插座 3放置于电脑主机外部, 其内置继电器 KR采用单稳态电磁继电器; 使用 本装置时应先将电脑的主机电源开关 P-SW从主板电源开关输入端口 P-SW+/-断开, 电脑主机 电源开关 P-SW连接于主控制器 1 的主机电源开关输入端口 P- SW- IN, 电脑主电源输出端口 DC - OUT包括电路的接地使用主机电源盒一个空闲的主电源输出插头 (+12V GND GND +5V), 连接主控制器 1的主电源输入端口 DC-IN, 主控制器 1的受控电源开关转接端口 P-SW- OUT连 接主板电源开关输入端口 P-SW+/-, 主控制器 1的继电器控制端口 KR- OUT通过挡板式连接器 2上的接插件 X- 1与受控电源插座 3内置继电器 KR的驱动线圈连接, 电脑主机 5和电脑系统 各外设 4由受控电源插座 3提供交流电源; 在主控制器 1中, YF1、 YF2、 YF3、 YF4构成一个 D锁存器, 其数据输入端为 D, 钟控端为 CP, 同相输出端为 Q, 反相输出端为 ^, D锁存器逻 辑功能为: 在 CP=1时, Q=D, Q =D φ, 在 CPO时, 保持 Q、 在 CP下降沿之前的输出状态 不变; 在主控制器 1中, IC5及其外围元件 R22、 R23、 R24、 R25、 C6、 C7、 C8、 L8、 VD10构 成一个直流-直流 (DC- DC) 转换电路, 其功能是将输入的直流电压转换为固定的 12V输出, 此电路为继电器驱动电路; 在主控制器 1中, 电路采用电池供电方式, 因继电器动作时所需 驱动电流较大, 使用一组电池时会对逻辑电路产生干扰, 所以主控制器 1 使用了两组电池 GB- 1、 GB-2分别对逻辑电路和继电器驱动电路进行独立供电, 以提髙电路的可靠性; 在主控 制器 1中, Fl、 F2、 R3、 R4和 F3、 F4、 R6、 R7构成两个施密特触发器, 以增强电路的抗干 扰能力。

当按下主机电源开关 P-SW后, F3、 F4翻转, F3输出 1电平, 送至 YF5的 b端, 此时 YF5 的 a端为 0电平, YF5输出不变, F3输出的 1电平还送至 YF7的 b端, 此时 YF7的 a端为 1 电平, YF7翻转输出 0电平, YF8输出 1电平, VT1导通,迅速将 C3放电,主机电源开关 P-SW 释放后, F3、 F4、 YF7、 YF8、 VT1恢复, YF7输出 1电平, VT1截止, C3由 R9进行充电, C3 的 +端能够保持一段时间的 0电平, C3的 +端的 0电平使 SYF2、 SYF3翻转, SYF3输出 0 电平, 一路送入 SYF1的 b端, 使 SYF1翻转输出 1电平, VT3、 VT4导通, 控制电池组 GB-2 为继电器驱动电路供电,在继电器控制端口 KR-0UT输出 12V电压,经由挡板式连接器 2送往 受控电源插座 3内置继电器 KR的驱动线圈, 接通交流电源, 电脑系统各外设 4直接启动, 电 脑主机 5则进入待命状态, 与此同时, SYF3输出的 0电平, 另一路还通过 R13对 C4进行充 电, 使 SYF4的 b端电压逐渐下降, 经 R13、 C4延时后, SYF4翻转, 输出 1电平, VT2导通, 使受控电源开关转接端口 P-SW-0UT对地低阻状态, 由 VD5或 VD6使主板电源开关输入端口 P-SW+/-中的 +端对地导通, 以启动电脑主机 5, R13、 C4的时间常数决定电脑主机 5的延迟 启动时间, R9、 C3的时间常数必须大于 R13、 C4的时间常数, 电路中, R9、 C3的时间常数 为 6. 8S, R13、 C4的时间常数为 2. 2S; 当电脑主机 5开机后, 主电源输出端口 DC- OUT产生 输出, 输入主控制器 1的主电源输入端口 DC- IN, 其中的 +12V主电源经 Rl、 R2分压, 使 Fl、 F2翻转, F1输出 0电平, F5翻转, 输出 1电平, C5经由 R17、 VD7放电, VD7对 SYF1的 a 端进行箝位, 使其电压不会过高, SYF1的 a端保持 1电平不变, C5放电为电脑关机时的继电 器延时供电做好准备,电脑主机 5开机后产生的 +12V主电源使 F2输出 1电平,送入由 YF1-YF4 构成的 D锁存器的 D端, 在电脑正常操作情况下, 由于此时主机电源开关 P- SW已释放, CP 已经恢复为 1电平, 所以 输出 0电平, 送入 YF7的 a端, 使 YF7在电脑开机期间的输出保 持 1电平不变, 进而使 YF8保持 0电平, VT1保持截止状态, 输出的 0电平同时输入 YF6, 使 YF6翻转, 输出 1电平, 经 R8、 VD1对 C3充电, C3的 +端电压快速升高,使 SYF2、 SYF3 再次翻转, SYF3输出 1电平, 送往 SYF1的 b端, 此时, SYF1的 a端为 1电平, SYF1翻转, 输出 0电平, VT3、 VT4截止, 切断电池组 GB- 2的输出, 由于此时 +12V主电源已经经由 VD8 对继电器驱动电路进行供电, 所以继电器控制端口 KR- OUT不会失电, 继电器 KR由主电源供 电,保持吸合状态, SYF3输出的 1电平还经 VD3、 R12对 C4进行放电,经短暂延时后,将 SYF4 的 b端置 1电平, 而此时 YF5的 a端为 1电平, b端为 0电平, YF5输出 1电平, SYF4的 a 端为 1电平, 所以 SYF4输出 0电平, VT2截止, 受控电源开关转接端口 P- SW- OUT恢复对地 的髙阻状态,在电脑正常启动情况下,受控电源开关转接端口 P-SW- OUT对地低阻状态的保持 时间主要由电脑主机 5的启动反应时间及 R8、 C3和 R12、 C4的时间常数决定, 至此, 电脑进 入正常工作状态。

当电脑使用完毕关机后, 电脑主机 5的 +12V主电源失电, Fl、 F2翻转, F2输出的 0电 平送入 D锁存器 D端, 输出 1电平, 送入 YF7的 a端, 此时 YF7的 b端为 0电平, 所以 YF7 输出保持不变, 输出的 1电平, 使 YF6翻转输出的 0电平, 由于 VD1的隔离作用不会对 C3 产生影响, F1翻转输出的 1电平送入 F5, F5输出 0电平, 经 R16对 C5进行充电, 在 SYF1 的 a端产生一个由 R16、 C5的时间常数控制的 0电平,在此期间, SYF1输出 1电平,控制 VT3、 VT4导通, 由电池组 GB-2对继电器驱动电路供电, 使继电器 KR在电脑主机 5关机后仍能保 持一段时间的吸合状态, R16、 C5的时间常数决定电脑外设的延迟关闭时间, 电路中 R16、 C5 的时间常数为 2. 2S, 在逻辑上, 虽然 +12V主电源失电在前, Fl、 F5、 SYF1翻转在后, 但其 过程短暂, 由于 C6、 C8的储能作用以及继电器的回差特性, 继电器 KR在此过程中不会释放, 电路在经 R16、 C5延时后, 继电器 KR失电释放, 电脑系统交流电源被彻底切断, 各逻辑门恢 复初始状态; 电脑待机和重启时, 电脑主机 5的 +12V主电源不变, 控制装置状态也不会发生 变化, 如因停电等因素使电脑主机 5的 +12V主电源消失, 控制装置运行关机过程, 将电脑系 统与交流电源脱离。
③图 4所示实施例的非正常情况说明:在主控制器 1中, 由 YF1- YF4构成的 D锁存器的 CP端为 0电平时, 保持 在 CP端下降沿之前的输出状态不变, 在主机电源开关 (P-SW) 处 于接通状态期间, D锁存器的 CP端被置为 0电平, 的输出电平被锁定, 不会因 D端的电 平改变而改变,在电脑启动时长时间压住主机电源开关 P-SW不放的非正常操作情况下, 以及 在电脑开机后长按主机电源开关 P-SW进行强制关机的情况下, D锁存器可防止 YF6、 YF7在 此期间反复翻转, 而使电脑反复启动, 在正常操作情况下, D锁存器的 D端输入, 端输出, 其逻辑作用相当于一个非门; 在主控制器 1中, C3与 VT1的导通电阻及 R8、 R9构成一个可 变时间常数电路, 在电脑启动过程中, 按下主机电源开关 P- SW时, 由 VT1的导通电阻对 C3 快速放电, 释放主机电源开关 P-SW后, 由 R9对 C3充电, 电脑主机启动后, 由 R8对 C3快速 充电, 在电脑主机由于故障等原因而未能启动的非正常情况下, 电路在经 R9、 C3延时后, 控 制装置将自动断开继电器 KR, 关闭交流电源。 ©图4所示实施例中主控制器 1的电路说明:在主控制器 1中,采用由 IC5及其外围元 件构成的直流 -直流 (DC- DC)转换电路作为继电器驱动电路, 其作用是将输入的直流电压转 换为固定的 12V输出,采用此电路的目的是为了充分利用电池组 GB-2的电能,在电池组 GB - 2 由于长期使用而电量不足的情况下, 使继电器仍能可靠工作, 电路中, L8未采用常规的单电 感方式, 而采用了变压器耦合方式, 且 +12V主电源也接入电路的输入端, 是为了利用 IC5的 输出限流功能, 防止继电器控制端口 KR- OUT意外短路而损坏电路, 在电池组 GB-2输出电压 与继电器 KR的驱动电压一致时, 此电路可以取消; 在主控制器 1中, 电路结构采用了微功耗 设计, 电池组 GB-1的使用时间可以达到或超过电脑主机的正常使用寿命, 电池组 GB- 2仅在 电脑开关机时提供驱动继电器所需的大电流, 电脑的开关机操作是使用频率较低的动作, 在 使用长保质期大容量电池的情况下, 电池组 GB- 2在电脑主机的正常使用寿命内不用更换;在 主控制器 1中, 各逻辑门使用 4000系列 CMOS (互补金属氧化物)标准数字集成电路, YF8、 VTl的作用是为了弥补 CMOS电路驱动能力不足的问题, 在电脑启动按下主机电源开关 P - SW 时, VT1可对 C3进行快速彻底地放电, 以防止由于电脑主机电源开关 P-SW按下时间过短, 造成 C3放电不彻底, 而使启动失败, YF8、 VTl在电路中的逻辑作用相当于一个与 R9并联的 二极管; 在主控制器 1中, R13、 C4的时间常数决定电脑主机的延迟启动时间, R16、 C5的时 间常数决定电脑外设的延迟关闭时间, 可通过调整其时间常数改变电脑主机的延迟启动时间 和电脑外设的延迟关闭时间; 在主控制器 1中, VD5、 VD6的作用是为了允许主控制器 1的 受控电源开关转接端口 P-SW-0UT与主板电源开关输入端口 P-SW+/-连接时可正接、 反接; 在 主控制器 1中, 电感 L1-L7对线路的高频信号进行衰减, 以提高装置的电磁兼容性; 在主控 制器 1中, IC1的第六个反相器未予使用,其输入端与 IC1的 14脚或 7脚接通,输出端空置, 因其对电路无影响, 所以图 4中未画出。
在图 4所示实施例中: 若增加充电电路, 则可使装置能够相应使用二次电池, 在电脑主 机开机状态, 由主电源对其进行充电; 若增加双稳态继电器驱动电路, 则可使装置能够相应 使用双稳态继电器, 以降低装置在电脑开机状态时的功耗, 另外, 装置也可使用固态继电器; 在主控制器 1中, 电路由与非门、 非门、 二极管和微分、 积分电路完成逻辑运算, 也可将其 等效变换, 采用其它形式的门电路, 或者使用微功耗单片机、 定制专用集成电路等方式完成 逻辑运算。
