技术领域technical field

本发明涉及一种用以控制电子装置关机的方法、元件以及电路板，并且特别涉及一种用以控制电子装置强制关机(force shutdown)的方法、元件以及电路板。The present invention relates to a method, component and circuit board for controlling shutdown of an electronic device, and in particular to a method, component and circuit board for controlling forced shutdown of an electronic device.

背景技术Background technique

随着电子相关技术的快速发展，计算机、移动电话等电子装置已成为现代人生活中不可或缺的辅助工具。通常，各类电子装置中都会包含主板(Mother Board)，主板上设置有执行各种功能的芯片组；电阻、电容等无源元件；以及供各种功能性电路板插接的插槽。并且，各芯片组、无源元件以及插槽之间通过细密而复杂的电路进行连接。With the rapid development of electronic related technologies, electronic devices such as computers and mobile phones have become indispensable auxiliary tools in modern life. Generally, various electronic devices will include a motherboard (Mother Board), which is provided with a chipset for performing various functions; passive components such as resistors and capacitors; and slots for various functional circuit boards to be plugged in. Moreover, each chipset, passive components, and sockets are connected through fine and complex circuits.

请参见图1，其所示为先前技术中的主板功能方框图。主板7的主要架构由中央处理器70、北桥芯片72、南桥芯片74、基本输入/输出系统(Basic Input/Output System，BIOS)芯片76以及输入/输出控制芯片78所构成。其中，北桥芯片72负责中央处理器70、主存储器710以及显示装置(未显示于图中)之间的数据传输及控制；南桥芯片74负责中央处理器70与BIOS芯片76以及部分周边装置的沟通，这些周边装置包含需要较高传输速度的接口扩充区730、存储装置732、网络控制元件734等等。另外，如串行端口750、并行端口752、键盘754、鼠标756以及电源供应器758等仅需较低传输速度的周边装置则由输入/输出控制芯片78进行控制。Please refer to FIG. 1 , which shows a functional block diagram of a motherboard in the prior art. The main frame of the motherboard 7 is composed of a central processing unit 70, a north bridge chip 72, a south bridge chip 74, a basic input/output system (Basic Input/Output System, BIOS) chip 76 and an input/output control chip 78. Wherein, the north bridge chip 72 is responsible for the data transmission and control between the central processing unit 70, the main memory 710 and the display device (not shown in the figure); the south bridge chip 74 is responsible for the communication between the central processing unit 70, the BIOS chip 76 and some peripheral devices For communication, these peripheral devices include interface expansion area 730, storage device 732, network control element 734, etc. that require higher transmission speed. In addition, the peripheral devices that only require lower transmission speed, such as the serial port 750 , the parallel port 752 , the keyboard 754 , the mouse 756 , and the power supply 758 , are controlled by the I/O control chip 78 .

此外，BIOS芯片76可针对主板7上的芯片组以及周边装置进行初始化设定，并且将操作系统自存储装置732加载到主存储器710中。进一步，BIOS芯片76还可供使用者设定电子装置的特定机制，例如网络唤醒(Wake On LAN，WOL)、键盘唤醒、鼠标唤醒等机制。In addition, the BIOS chip 76 can perform initialization settings for the chipset and peripheral devices on the motherboard 7 , and load the operating system from the storage device 732 into the main memory 710 . Further, the BIOS chip 76 can also be used by the user to set specific mechanisms of the electronic device, such as Wake On LAN (WOL), keyboard wakeup, mouse wakeup and other mechanisms.

以WOL为例，在电子装置进行正常关机时，操作系统会在关闭电源之前先呼叫BIOS芯片76启动WOL机制，再由BIOS芯片76将网络控制元件734、南桥芯片74等相关单元设定成可接受WOL的状态。在前述设定完成后，操作系统才控制电源供应器758中断电源。由此，使用者可通过远程服务器传送唤醒信号封包(例如，由AMD公司所提出的魔术封包(magic packet))至该网络控制元件734，该网络控制元件734再传送唤醒事件信号至南桥芯片74，而南桥芯片74根据该唤醒事件信号控制该电子装置开机。Taking WOL as an example, when the electronic device is normally shut down, the operating system will call the BIOS chip 76 to start the WOL mechanism before turning off the power, and then the BIOS chip 76 will set the network control element 734, the south bridge chip 74 and other related units to Acceptable WOL status. After the foregoing settings are completed, the operating system controls the power supply 758 to cut off the power. Thus, the user can send a wake-up signal packet (for example, the magic packet (magic packet) proposed by AMD) to the network control element 734 through a remote server, and the network control element 734 then sends a wake-up event signal to the south bridge chip 74, and the south bridge chip 74 controls the electronic device to start up according to the wake-up event signal.

此外，电子装置通常包含电源开关80，其连接输入/输出控制芯片78，并且该电源开关80可发送电源控制信号至输入/输出控制芯片78。当电源开关80处于正常状况时，电源控制信号具有第一电平(signal level)，而当电源开关80受到使用者按压时，电源控制信号的电平会变换为第二电平(通常，第二电平低于第一电平)。当输入/输出控制芯片78检测到电源控制信号的电平发生改变时，便会通知操作系统进行前述的关机程序。In addition, the electronic device usually includes a power switch 80 connected to the I/O control chip 78 , and the power switch 80 can send a power control signal to the I/O control chip 78 . When the power switch 80 is in a normal state, the power control signal has a first level (signal level), and when the power switch 80 is pressed by the user, the level of the power control signal will change to a second level (usually, the first level) The second level is lower than the first level). When the input/output control chip 78 detects that the level of the power control signal changes, it will notify the operating system to perform the aforementioned shutdown procedure.

然而，若电子装置进行不正常关机时，例如使用者持续按压电源开关80数秒钟导致电子装置强制关机，电源供应器758会直接中断电源，导致BIOS芯片76来不及设定网络控制元件734、南桥芯片74等相关单元，进而使WOL机制失效。同样地，其他需要在关机前由BIOS芯片76设定的机制皆可能因为电子装置进行不正常关机而失效。However, if the electronic device is shut down abnormally, for example, the user continues to press the power switch 80 for several seconds to force the electronic device to shut down, the power supply 758 will directly interrupt the power supply, causing the BIOS chip 76 to have no time to set the network control element 734, south bridge Related units such as the chip 74, and then make the WOL mechanism invalid. Similarly, other mechanisms that need to be set by the BIOS chip 76 before shutdown may fail due to abnormal shutdown of the electronic device.

具体实施方式Detailed ways

本发明提供一种用以控制电子装置关机的方法、元件以及电路板。特别地，根据本发明的方法、元件以及电路板能在电子装置强制关机时先设定该电子装置的多个预设机制，致使该电子装置能在强制关机后仍保有所述多个预设机制。于实际应用中，本发明所述的电子装置可以是台式计算机、笔记本计算机、平板计算机等，但不受限于此。The invention provides a method, component and circuit board for controlling shutdown of an electronic device. In particular, according to the method, component and circuit board of the present invention, a plurality of preset mechanisms of the electronic device can be set first when the electronic device is forcibly shut down, so that the electronic device can still maintain the plurality of preset mechanisms after the forced shutdown mechanism. In practical applications, the electronic device described in the present invention may be a desktop computer, a notebook computer, a tablet computer, etc., but is not limited thereto.

请参见图2，图2所示为根据本发明的一具体实施例的控制元件的功能方框图。如图2所示，该控制元件10连接一电子装置(未显示于图中)的电源开关20与电源供应器24以及一处理模块22；控制元件10是用以接收电源开关20传送的电源控制信号，且其包含一暂存模块102、一计算模块104以及一判断模块106。Please refer to FIG. 2 , which is a functional block diagram of a control element according to a specific embodiment of the present invention. As shown in Figure 2, the control element 10 is connected to a power switch 20, a power supply 24 and a processing module 22 of an electronic device (not shown in the figure); the control element 10 is used to receive the power control transmitted by the power switch 20 signal, and it includes a temporary storage module 102 , a calculation module 104 and a judgment module 106 .

暂存模块102可记录来自电源开关20所提供的电源控制信号目前电平。计算模块104连接暂存模块102，用以当目前电平符合预设电平时，计算电源控制信号处于预设电平的持续时间。The temporary storage module 102 can record the current level of the power control signal provided by the power switch 20 . The calculation module 104 is connected to the temporary storage module 102 for calculating the duration of the power control signal at the preset level when the current level matches the preset level.

于实际应用中，电源控制信号在电源开关20未被按压时具有如前述的第一电平(例如，1)，而预设电平可以设为如前述的第二电平(例如，0)。因此，当使用者按压电源开关20时，电源控制信号的电平变化为第二电平0，因此符合预设电平。此时，计算模块104便开始计时，以计算电源控制信号处于预设电平的持续时间。In practical application, the power control signal has the aforementioned first level (eg, 1) when the power switch 20 is not pressed, and the preset level can be set as the aforementioned second level (eg, 0). . Therefore, when the user presses the power switch 20 , the level of the power control signal changes to the second level 0, thus meeting the preset level. At this time, the calculation module 104 starts timing to calculate the duration of the power control signal at the preset level.

判断模块106则连接计算模块104，用以将计算模块104所计算的持续时间与一预设阈值作比较，以判断持续时间是否大于预设阈值。于实际应用中，预设阈值可由控制元件10的设计者或使用者进行设定，例如，但不受限于2秒、3秒、4秒、5秒、10秒等等。The judgment module 106 is connected to the calculation module 104 for comparing the duration calculated by the calculation module 104 with a preset threshold to determine whether the duration is greater than the preset threshold. In practical applications, the preset threshold can be set by the designer or user of the control element 10, for example, but not limited to 2 seconds, 3 seconds, 4 seconds, 5 seconds, 10 seconds and so on.

若判断模块106判断电源控制信号处于预设电平的持续时间大于预设阈值时，判断模块106产生中断信号，并且将中断信号传送至处理模块22，以驱动处理模块22根据中断信号设定电子装置的一个或多个预设机制。If the judging module 106 judges that the duration of the power control signal at the preset level is greater than the preset threshold, the judging module 106 generates an interrupt signal, and transmits the interrupt signal to the processing module 22, so as to drive the processing module 22 to set the power supply control signal according to the interrupt signal. One or more default mechanisms of the device.

于实际应用中，本发明的预设机制可以是唤醒机制、警示机制等。进一步，唤醒机制可以是网络唤醒机制、鼠标唤醒机制、键盘唤醒机制或其他适当的唤醒机制。In practical applications, the preset mechanism of the present invention may be a wake-up mechanism, an alert mechanism, and the like. Further, the wake-up mechanism may be a network wake-up mechanism, a mouse wake-up mechanism, a keyboard wake-up mechanism or other appropriate wake-up mechanisms.

当然，本发明所述的预设机制可以是其他适当的机制，而不受限于这里所举的例子。关于所述多个机制的相关内容将于以下的具体实施例中详述。Certainly, the preset mechanism described in the present invention may be other appropriate mechanisms, and is not limited to the examples mentioned here. Related content about the multiple mechanisms will be described in detail in the following specific embodiments.

此外，若判断模块106判断电源控制信号处于预设电平的持续时间小于预设阈值时，判断模块106可不进行任何动作。或者，判断模块106也可通知电子装置的操作系统进行前述的正常关机程序。In addition, if the judging module 106 judges that the duration of the power control signal at the preset level is less than the preset threshold, the judging module 106 may not take any action. Alternatively, the judging module 106 may also notify the operating system of the electronic device to perform the aforementioned normal shutdown procedure.

于实际应用中，当处理模块22于设定预设机制后，可产生并输出确认信号至控制元件10，使其根据确认信号控制电子装置的电源供应器24停止供电，以将电子装置关机。In practical applications, after the processing module 22 sets the default mechanism, it can generate and output a confirmation signal to the control element 10, so that it can control the power supply 24 of the electronic device to stop supplying power according to the confirmation signal, so as to shut down the electronic device.

综上所述，本发明的控制元件可在电子装置被强制关机时预先设定如前所述的机制，避免已知技术中电子装置因强制关机而导致所述多个机制丧失的问题，并降低使用者的困扰。To sum up, the control element of the present invention can preset the above-mentioned mechanism when the electronic device is forced to shut down, avoiding the problem of the loss of the multiple mechanisms caused by the forced shutdown of the electronic device in the known technology, and Reduce user annoyance.

请参见图3，图3所示为根据本发明的一具体实施例的控制电路板的功能方框图。如图3所示，该控制电路板3包含控制元件30、南桥芯片32以及处理模块34。于实际应用中，该控制电路板3可以是一主板，但不受限于此。Please refer to FIG. 3 , which is a functional block diagram of a control circuit board according to a specific embodiment of the present invention. As shown in FIG. 3 , the control circuit board 3 includes a control element 30 , a south bridge chip 32 and a processing module 34 . In practical applications, the control circuit board 3 may be a main board, but is not limited thereto.

控制元件30分别耦接电子装置(未显示于图中)的电源开关40与电源供应器42；控制元件30是用以自电源开关40接收电源控制信号，并且判断电源控制信号处于预设电平的持续时间是否大于预设阈值，若是，则控制元件30产生并输出中断信号。The control element 30 is respectively coupled to the power switch 40 and the power supply 42 of the electronic device (not shown in the figure); the control element 30 is used for receiving the power control signal from the power switch 40, and judging that the power control signal is at a preset level Whether the duration is greater than the preset threshold, if so, the control element 30 generates and outputs an interrupt signal.

于实际应用中，控制元件30可包含如前述的暂存模块302、计算模块304以及判断模块306。所述多个模块间的连接关系、运行方式及功能皆与前面所举的例子相同，在此不作赘述。需注意的是，所述多个模块可视情况被整合或分割，并不受限于任何特定的形式。此外，所述多个模块可能是以硬件或固件的形式存在。In practical applications, the control unit 30 may include the above-mentioned temporary storage module 302 , calculation module 304 and judgment module 306 . The connection relationship, operation mode and functions among the multiple modules are the same as the above examples, and will not be repeated here. It should be noted that the multiple modules can be integrated or divided as appropriate, and are not limited to any specific form. In addition, the plurality of modules may exist in the form of hardware or firmware.

南桥芯片32分别耦接控制元件30以及处理模块34，用以自控制元件30接收中断信号，并且将中断信号传送至处理模块34。如前所述，处理模块34可根据中断信号设定电子装置的预设机制。The south bridge chip 32 is respectively coupled to the control element 30 and the processing module 34 for receiving the interrupt signal from the control element 30 and transmitting the interrupt signal to the processing module 34 . As mentioned above, the processing module 34 can set the preset mechanism of the electronic device according to the interrupt signal.

如前所述，于实际应用中，当处理模块34于设定预设机制后，其可产生并输出确认信号至控制元件30，并且控制元件30根据确认信号控制电子装置的电源供应器42停止供电，以将电子装置关机。As mentioned above, in practical applications, after the processing module 34 sets the default mechanism, it can generate and output a confirmation signal to the control element 30, and the control element 30 controls the power supply 42 of the electronic device to stop according to the confirmation signal. supply power to shut down the electronic device.

于实际应用中，本发明的处理模块34可以是一基本输入/输出系统模块或一嵌入式控制模块(embedded control module)，但不受限于此。此外，本发明的处理模块34可能是以硬件或固件的形式存在。In practical application, the processing module 34 of the present invention can be a basic input/output system module or an embedded control module (embedded control module), but is not limited thereto. In addition, the processing module 34 of the present invention may exist in the form of hardware or firmware.

请再参见图4，图4所示为根据本发明的另一具体实施例的控制电路板的功能方框图。如图4所示，该控制电路板3除了图3所示的控制元件30、南桥芯片32以及处理模块34之外，还包含中央处理器36、北桥芯片37以及网络控制元件38。当然，于实际应用中，该控制电路板3还可包含其他适当的元件。Please refer to FIG. 4 again, which is a functional block diagram of a control circuit board according to another embodiment of the present invention. As shown in FIG. 4 , the control circuit board 3 includes a central processing unit 36 , a north bridge chip 37 and a network control component 38 in addition to the control component 30 , south bridge chip 32 and processing module 34 shown in FIG. 3 . Of course, in practical applications, the control circuit board 3 may also include other appropriate components.

中央处理器36可执行并控制电子装置的各种运算功能，而北桥芯片37分别耦接中央处理器36以及南桥芯片32，用以协助南桥芯片32与中央处理器间36的信号传递。于实际应用中，中央处理器36插接于控制电路板3上的专用插槽中，并且可被替换。此外，网络控制元件38连接至南桥芯片32，并且通过南桥芯片32与控制电路板3上的其他元件沟通。The central processing unit 36 can execute and control various computing functions of the electronic device, and the north bridge chip 37 is respectively coupled to the central processing unit 36 and the south bridge chip 32 to assist the signal transmission between the south bridge chip 32 and the central processing unit 36 . In practical applications, the CPU 36 is plugged into a dedicated slot on the control circuit board 3 and can be replaced. In addition, the network control component 38 is connected to the south bridge chip 32 and communicates with other components on the control circuit board 3 through the south bridge chip 32 .

如前所述，本发明的预设机制可以是唤醒机制、警示机制等。进一步，唤醒机制可以是网络唤醒机制、鼠标唤醒机制、键盘唤醒机制或其他适当的唤醒机制。As mentioned above, the preset mechanism of the present invention may be a wake-up mechanism, an alert mechanism, and the like. Further, the wake-up mechanism may be a network wake-up mechanism, a mouse wake-up mechanism, a keyboard wake-up mechanism or other appropriate wake-up mechanisms.

举例而言，当该预设机制为网络唤醒机制时，处理模块34设定网络控制元件38，致使该网络控制元件38能接收如先前所述的唤醒信号封包。并且，处理模块34还设定南桥芯片32，致使南桥芯片32能接收网络控制元件38根据该唤醒信号封包所产生的唤醒事件信号。借此，即使电子装置被强制关机，其仍可通过本发明的控制电路板3而保有网络唤醒机制。For example, when the default mechanism is the Wake-on-LAN mechanism, the processing module 34 sets the network control element 38 so that the network control element 38 can receive the wake-up signal packet as described above. Moreover, the processing module 34 also sets the south bridge chip 32 so that the south bridge chip 32 can receive the wake-up event signal generated by the network control element 38 according to the wake-up signal packet. In this way, even if the electronic device is forced to shut down, it can still maintain the wake-on-LAN mechanism through the control circuit board 3 of the present invention.

再举例而言，当该预设机制为警示机制时，处理模块34传送一驱动信号至网络控制元件38，并且网络控制元件38根据该驱动信号发送一警示信号至一监控端(未显示于图中)，以通知该监控端该电子装置将要关机。借此，该电子装置可在被强制关机时通知监控端，使该监控端或相关的监控人员能对此情况做适当处置，例如，传送唤醒信号以唤醒该电子装置。For another example, when the default mechanism is an alert mechanism, the processing module 34 sends a drive signal to the network control element 38, and the network control element 38 sends an alert signal to a monitoring terminal (not shown in the figure) according to the drive signal. middle), to notify the monitoring terminal that the electronic device will be shut down. In this way, the electronic device can notify the monitoring terminal when it is forced to shut down, so that the monitoring terminal or relevant monitoring personnel can properly deal with this situation, for example, sending a wake-up signal to wake up the electronic device.

请参见图5，图5所示为根据本发明的一具体实施例的控制方法的流程图。如图5所示，根据本发明的方法包含下列步骤：Please refer to FIG. 5 , which is a flowchart of a control method according to a specific embodiment of the present invention. As shown in Figure 5, the method according to the present invention comprises the following steps:

步骤S50，接收一电源控制信号，并且计算该电源控制信号处于一预设电平的持续时间。步骤S52，判断该持续时间是否大于一阈值。若步骤S52的判断为是(例如，使用者持续按压电源开关)，则进行步骤S54，产生一中断信号，并且将该中断信号传送至该电子装置的一处理模块。借由步骤S54，本发明的方法可驱动该处理模块根据该中断信号设定该电子装置的一预设机制。Step S50, receiving a power control signal, and calculating the duration of the power control signal at a predetermined level. Step S52, judging whether the duration is greater than a threshold. If the determination in step S52 is yes (for example, the user keeps pressing the power switch), then proceed to step S54 to generate an interrupt signal and send the interrupt signal to a processing module of the electronic device. Through step S54, the method of the present invention can drive the processing module to set a default mechanism of the electronic device according to the interrupt signal.

根据步骤S54，该处理模块于设定该预设机制后可产生并输出一确认信号(步骤S56)，并且，本发明的方法可进一步包含步骤S58，接收该确认信号，并且根据该确认信号控制该电子装置的电源供应器停止供电，以将该电子装置关机。According to step S54, the processing module can generate and output a confirmation signal after setting the default mechanism (step S56), and the method of the present invention can further include step S58, receiving the confirmation signal, and controlling the system according to the confirmation signal The power supply of the electronic device stops supplying power to shut down the electronic device.
