具体实施方式 Detailed ways
为让本发明的上述和其他目的、特征和优点能更明显易懂，下文特举出本发明的具体实施例，并配合所附附图，作详细说明如下。In order to make the above and other objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention are listed below and described in detail in conjunction with the accompanying drawings.
请先参考图1为本发明计算机系统的架构图。Please refer to FIG. 1 , which is an architecture diagram of the computer system of the present invention.
本发明的计算机系统1可为桌上型计算机或是笔记本型计算机等系统，但本发明并不以此为限。计算机系统1包括电源控制系统10、电源模块30、存储模块40以及芯片组50。电源模块30用以供应电源信号，并藉由电源控制系统10以决定是否能将电源信号传输至存储模块40及芯片组50。电源模块30包括用以供应主电源信号，如利用外部电源及电池供应，或是利用备用电池供应的备用电源信号。The computer system 1 of the present invention can be a system such as a desktop computer or a notebook computer, but the present invention is not limited thereto. The computer system 1 includes a power control system 10 , a power module 30 , a storage module 40 and a chipset 50 . The power module 30 is used for supplying power signals, and the power control system 10 determines whether the power signals can be transmitted to the storage module 40 and the chipset 50 . The power module 30 includes a main power signal for supplying, for example, an external power supply and a battery, or a backup power signal supplied by a backup battery.
存储模块40为一互补式金属氧化物半导体(Complementary Metal OxideSemiconductor，CMOS)，用以储存数据以提供计算机系统1的基本输入输出系统(BasicInput Output System，BIOS)执行之用。在一般的情况下，计算机系统1关机时，存储模块40藉由备用电池的备用电源信号，使其实时时钟(Real Time Clock，RTC)组件仍可持续作用。如此一来，计算机系统1开机时即可读取正确的时间。芯片组50可为计算机系统1的南桥芯片，但本发明并不以此为限。在一般的情况下，计算机系统1关机时，主电源信号仍会提供芯片组50些许的电源。此时即称为系统电源状态S5。The storage module 40 is a Complementary Metal Oxide Semiconductor (CMOS), used to store data for the implementation of the Basic Input Output System (BIOS) of the computer system 1 . In general, when the computer system 1 is turned off, the memory module 40 keeps its real time clock (RTC) component still functioning continuously through the backup power signal of the backup battery. In this way, the computer system 1 can read the correct time when it is turned on. The chipset 50 can be a south bridge chip of the computer system 1, but the invention is not limited thereto. Generally, when the computer system 1 is turned off, the main power signal still provides some power to the chipset 50 . This is called the system power state S5.
电源控制系统10用以控制传输至存储模块40及芯片组50的电源信号。电源控制系统10包括控制模块11、输入信号模块12、第一开关电路21以及第二开关电路22。控制模块11可为嵌入式控制器(Embedded controller)或是键盘控制器(Keyboard Controller)，但本发明并不以此为限。输入信号模块12与控制模块11电性连接，用以输入信号至控制模块11。输入信号模块12所输入的信号可为利用组合键持续按压所键入的信号。如此一来，即可避免使用者误触。其组合键是先利用控制模块11作设定。举例而言，可藉由控制模块11设定使用者需先按压下Fn及C键，同时按压下电源开关键一段时间后，才会输入信号。但本发明并不以上述的按压方式为限。The power control system 10 is used for controlling power signals transmitted to the storage module 40 and the chipset 50 . The power control system 10 includes a control module 11 , an input signal module 12 , a first switch circuit 21 and a second switch circuit 22 . The control module 11 can be an embedded controller (Embedded controller) or a keyboard controller (Keyboard Controller), but the present invention is not limited thereto. The input signal module 12 is electrically connected to the control module 11 for inputting signals to the control module 11 . The signal input by the input signal module 12 may be a signal entered by continuously pressing the combination key. In this way, the user can avoid touching by mistake. Its combination key is to utilize control module 11 to make setting earlier. For example, the control module 11 can be used to set the user to first press the Fn and C keys, and at the same time press the power switch key for a period of time before inputting a signal. But the present invention is not limited to the above pressing method.
第一开关电路21与控制模块11、电源模块30以及存储模块40电性连接。当第一开关电路21导通时，能够同时供应存储模块40电源信号，包括主电源信号及备用电源信号。控制模块11控制第一开关电路21的断路或导通，以决定存储模块40是否能够接收其电源信号。同样地，第二开关电路22与控制模块11、电源模块30以及芯片组50电性连接。当第二开关电路22导通时，能够供应芯片组50主电源信号。控制模块11控制第二开关电路22的断路或导通，以决定芯片组50是否能够接收主电源信号。The first switch circuit 21 is electrically connected to the control module 11 , the power module 30 and the storage module 40 . When the first switch circuit 21 is turned on, it can simultaneously supply power signals to the storage module 40 , including main power signals and backup power signals. The control module 11 controls the disconnection or conduction of the first switch circuit 21 to determine whether the storage module 40 can receive its power signal. Likewise, the second switch circuit 22 is electrically connected to the control module 11 , the power module 30 and the chipset 50 . When the second switch circuit 22 is turned on, the main power signal of the chipset 50 can be supplied. The control module 11 controls the disconnection or conduction of the second switch circuit 22 to determine whether the chipset 50 can receive the main power signal.
接着请参考图2关于本发明电源控制方法的流程图。此处需注意的是，以下虽以具有电源控制系统10的计算机系统1为例说明本发明的电源控制的方法，但本发明的电源控制方法并不以使用在电源控制系统10为限。Next, please refer to FIG. 2 for a flowchart of the power control method of the present invention. It should be noted here that although the computer system 1 with the power control system 10 is used as an example to illustrate the power control method of the present invention, the power control method of the present invention is not limited to be used in the power control system 10 .
首先进行步骤201：藉由电源控制系统判断是否输入一信号。First, go to step 201: judge whether to input a signal by the power control system.
首先电源控制系统10先判断输入信号模块12是否有输入一信号。例如控制模块11利用扫描键盘阵列的方式来判断是否有组合键被按压，或者是组合键是否有依照特定顺序被按压。Firstly, the power control system 10 judges whether a signal is input to the input signal module 12 . For example, the control module 11 judges whether a combination key is pressed by scanning the keyboard array, or whether the combination key is pressed according to a specific order.
若是，则进行步骤202：判断是否持续输入达到一第一特定时间。If yes, proceed to step 202: determine whether the continuous input reaches a first specific time.
控制模块11再判断此信号是否持续输入达到第一特定时间。例如组合键被持续按压超过八秒以上。第一特定时间可藉由控制模块11进行设定。The control module 11 then judges whether the signal continues to be input for a first specific time. For example, the combination key is continuously pressed for more than eight seconds. The first specific time can be set by the control module 11 .
若是，则进行步骤203。若没有持续输入到第一特定时间，则有可能为使用者误触到组合键，因此电源控制系统10就不会动作。If yes, go to step 203 . If the input is not continued until the first specified time, the user may touch the combination key by mistake, so the power control system 10 will not act.
步骤203：控制一第一开关电路及一第二开关电路，以切断电源信号。Step 203: Control a first switch circuit and a second switch circuit to cut off the power signal.
控制模块11即控制第一开关电路21及第二开关电路22，使其断路。如此一来，存储模块40及芯片组50即完全无法接收到电源信号，包括在系统电源状态S5下的主电源信号及备用电源信号。The control module 11 controls the first switch circuit 21 and the second switch circuit 22 to turn them off. As a result, the memory module 40 and the chipset 50 cannot receive power signals at all, including the main power signal and the standby power signal in the system power state S5.
最后进行步骤204：等待一第二特定时间后，再恢复电源信号。Finally, go to step 204: wait for a second specific time, and then restore the power signal.
控制模块11经过第二特定时间后，例如等待三秒钟后，再控制第一开关电路21及第二开关电路22，使其导通。如此一来即恢复供电，存储模块40及芯片组50可接收到主电源信号及备用电源信号。经由上述的步骤203断电及步骤204恢复供电的流程，存储模块40及芯片组50即可重新启动。The control module 11 controls the first switch circuit 21 and the second switch circuit 22 to turn on after the second specific time elapses, for example, after waiting for three seconds. In this way, the power supply is restored, and the storage module 40 and the chipset 50 can receive the main power signal and the standby power signal. Through the process of powering off in step 203 and restoring power in step 204, the storage module 40 and the chipset 50 can be restarted.
此处需注意的是，本发明的电源控制方法并不以上述的步骤次序为限，只要能达到本发明的目的，上述的步骤次序亦可加以改变。It should be noted here that the power control method of the present invention is not limited to the above-mentioned step sequence, as long as the purpose of the present invention can be achieved, the above-mentioned step sequence can also be changed.
利用本发明的电源控制系统10及方法，即可在不拆除计算机系统1的硬件架构下，对存储模块40及芯片组50进行重置。尤其是对于将备用电源信号切断的流程而言，并不需要将备用电池拆除。因此可节省下许多的工作量，亦可避免损坏到计算机系统1的硬件。Using the power control system 10 and the method of the present invention, the storage module 40 and the chipset 50 can be reset without dismantling the hardware structure of the computer system 1 . Especially for the process of cutting off the backup power signal, it is not necessary to remove the backup battery. Therefore, a lot of workload can be saved, and damage to the hardware of the computer system 1 can also be avoided.
综上所陈，本发明无论就目的、手段及功效，处处均显示其迥异于公知技术的特征，恳请审查员明察，早日赐准专利，使嘉惠社会，实感德便。惟应注意的是，上述诸多实施例仅是为了便于说明而举例而已，本发明所要求保护的权利范围自然应当以权利要求书范围所述为准，而非仅限于上述实施例。To sum up, the present invention, regardless of its purpose, means, and efficacy, shows its characteristics that are completely different from the known technology. I urge the examiner to be aware of it and grant a patent as soon as possible to benefit the society. I really appreciate it. However, it should be noted that the above-mentioned embodiments are examples only for the convenience of description, and the scope of rights claimed in the present invention should naturally be based on the scope of the claims, rather than limited to the above-mentioned embodiments.
