依據以下一或多個實施例描述的方法及系統可用於保護電源供應裝置中的電力傳輸電路。為了更詳細說明保護方式，請先參考圖1，其中圖1係依據本發明一實施例所繪示的電源保護系統的方塊圖。如圖1所示，電源保護系統1包括第一電力傳輸電路11、第二電力傳輸電路12、電源偵測器13以及控制裝置14。第一電力傳輸電路11及第二電力傳輸電路12連接於電源A1。電源偵測器13連接於第一電力傳輸電路11的輸入端的線路及輸出端的線路，以及第二電力傳輸電路12的輸入端的線路及輸出端的線路。控制裝置14連接於第一電力傳輸電路11、第二電力傳輸電路12以及電源偵測器13。The method and system described in accordance with one or more of the following embodiments can be used to protect the power transmission circuit in the power supply device.

The power source A1 can be mains electricity. For example, the electronic device can be a desktop computer or a laptop. Furthermore, the electronic device can be a graphics card, and the present invention is not limited to the type of electronic device.

請一併參考圖1及圖2，其中圖2係依據本發明一實施例所繪示的電源保護方法的流程圖。如圖2所示，電源保護方法包括：步驟S101：取得多個電力傳輸電路的多個電力參數；步驟S103：判斷所述多個電力參數是否大於各自對應的預設值；當步驟S103的判斷結果為「否」時，再次執行步驟S101；當步驟S103的判斷結果為「是」時，執行步驟S105：關斷所述多個電力傳輸電路中的一或多個對應電路；步驟S107：計時所述一或多個對應電路被關斷的關斷時間；步驟S109：判斷關斷時間是否等於或大於預設時間；當步驟S109的判斷結果為「否」時，執行步驟S107；以及當步驟S109的判斷結果為「是」時，執行步驟S111：導通所述一或多個對應電路。Please refer to FIG. 1 and FIG. 2, wherein FIG. 2 is a flow chart of a power protection method according to an embodiment of the present invention. As shown in FIG. 2, the power protection method includes: step S101: obtaining multiple power parameters of multiple power transmission circuits; step S103: determining whether the multiple power parameters are greater than the corresponding preset values; when the determination result of step S103 is "no", executing step S101 again; when the determination result of step S103 is "yes", executing step S105: shutting down the multiple power transmission circuits; one or more corresponding circuits in the transmission circuit; step S107: timing the off time when the one or more corresponding circuits are turned off; step S109: judging whether the off time is equal to or greater than a preset time; when the judgment result of step S109 is "no", executing step S107; and when the judgment result of step S109 is "yes", executing step S111: turning on the one or more corresponding circuits.

於步驟S101，控制裝置14從電源偵測器13取得第一電力傳輸電路11的電力參數及第二電力傳輸電路12的電力參數。如前所述，電力參數可為第一電力傳輸電路11及第二電力傳輸電路12各自的輸入電力及輸出電力的電壓值或電流值。In step S101, thecontrol device 14 obtains the power parameters of the firstpower transmission circuit 11 and the secondpower transmission circuit 12 from thepower detector 13. As mentioned above, the power parameters may be the voltage value or current value of the input power and the output power of the firstpower transmission circuit 11 and the secondpower transmission circuit 12, respectively.

於步驟S103，控制裝置14判斷第一電力傳輸電路11及第二電力傳輸電路12的每一者的電力參數是否大於各自對應的預設值。舉例而言，當電力傳輸電路為電容器時，預設值可為11.4伏特或12伏特，其他電力傳輸電路的預設值亦可為11.4伏特或12伏特，且預設值可不大於13.5伏特，但本發明不予以限制。In step S103, thecontrol device 14 determines whether the power parameter of each of the firstpower transmission circuit 11 and the secondpower transmission circuit 12 is greater than the corresponding preset value. For example, when the power transmission circuit is a capacitor, the preset value may be 11.4 volts or 12 volts, and the preset value of other power transmission circuits may also be 11.4 volts or 12 volts, and the preset value may not be greater than 13.5 volts, but the present invention is not limited thereto.

當控制裝置14判斷第一電力傳輸電路11的電力參數不大於對應的預設值，且第二電力傳輸電路12的電力參數不大於對應的預設值時，表示第一電力傳輸電路11及第二電力傳輸電路12的輸入電力及輸出電力都落於正常範圍。因此，控制裝置14可再次執行步驟S101，以繼續對第一電力傳輸電路11及第二電力傳輸電路12進行監測。When thecontrol device 14 determines that the power parameter of the firstpower transmission circuit 11 is not greater than the corresponding preset value, and the power parameter of the secondpower transmission circuit 12 is not greater than the corresponding preset value, it means that the input power and output power of the firstpower transmission circuit 11 and the secondpower transmission circuit 12 are both within the normal range. Therefore, thecontrol device 14 can execute step S101 again to continue monitoring the firstpower transmission circuit 11 and the secondpower transmission circuit 12.

當控制裝置14判斷第一電力傳輸電路11及第二電力傳輸電路12中的一或多者的電力參數大於對應的預設值，表示具有大於對應預設值之電力參數的電力傳輸電路（後稱對應電路）的輸入電力及/或輸出電力落於正常範圍外。因此，控制裝置14執行步驟S105，以關斷電力參數大於對應的預設值的一或多個對應電路。舉例而言，控制裝置14可關斷對應電路的輸入端的開關元件及關斷對應電路的輸出端的開關元件，其中開關元件可包括繼電器或電晶體，本發明不予以限制。為便於說明，以下假設第一電力傳輸電路11為對應電路（即電力參數大於預設值的電力傳輸電路），第二電力傳輸電路12非為對應電路（即電力參數不大於預設值的電力傳輸電路）。When thecontrol device 14 determines that the power parameter of one or more of the firstpower transmission circuit 11 and the secondpower transmission circuit 12 is greater than the corresponding preset value, it means that the input power and/or output power of the power transmission circuit having the power parameter greater than the corresponding preset value (hereinafter referred to as the corresponding circuit) falls outside the normal range. Therefore, thecontrol device 14 executes step S105 to shut down one or more corresponding circuits whose power parameters are greater than the corresponding preset value. For example, thecontrol device 14 can shut down the switch element at the input end of the corresponding circuit and the switch element at the output end of the corresponding circuit, wherein the switch element may include a relay or a transistor, and the present invention is not limited thereto. For ease of explanation, it is assumed below that the firstpower transmission circuit 11 is a corresponding circuit (i.e., a power transmission circuit whose power parameter is greater than a preset value), and the secondpower transmission circuit 12 is not a corresponding circuit (i.e., a power transmission circuit whose power parameter is not greater than a preset value).

於步驟S107，控制裝置14計時第一電力傳輸電路11的關斷時間。進一步而言，控制裝置14在關斷第一電力傳輸電路11後開始計時，以取得對應第一電力傳輸電路11的關斷時間。In step S107, thecontrol device 14 counts the off time of the firstpower transmission circuit 11. Specifically, thecontrol device 14 starts counting after the firstpower transmission circuit 11 is turned off, so as to obtain the off time corresponding to the firstpower transmission circuit 11.

於步驟S109，控制裝置14判斷關斷時間是否等於或大於預設時間。預設時間可為使第一電力傳輸電路11的電力參數降低至預設值的時間，及/或使第一電力傳輸電路11的溫度值降低至預設溫度的時間。預設時間例如為20毫秒，但本發明不予以限制。In step S109, thecontrol device 14 determines whether the shutdown time is equal to or greater than a preset time. The preset time may be the time for the power parameter of the firstpower transmission circuit 11 to decrease to a preset value, and/or the time for the temperature of the firstpower transmission circuit 11 to decrease to a preset temperature. The preset time is, for example, 20 milliseconds, but the present invention is not limited thereto.

當控制裝置14判斷關斷時間小於預設時間時，控制裝置14可再次執行步驟S107，即繼續計時關斷時間。當控制裝置14判斷關斷時間等於或大於預設時間時，控制裝置14導通第一電力傳輸電路11。換言之，當關斷時間等於或大於預設時間時，表示第一電力傳輸電路11的電力參數可能已經降低至預設值，及/或第一電力傳輸電路11的溫度值降低至預設溫度。因此，控制裝置14導通第一電力傳輸電路11，以使第一電力傳輸電路11可再次從電源A1接收電力，及輸出電力至電子裝置。When thecontrol device 14 determines that the shutdown time is less than the preset time, thecontrol device 14 may execute step S107 again, that is, continue to count the shutdown time. When thecontrol device 14 determines that the shutdown time is equal to or greater than the preset time, thecontrol device 14 turns on the firstpower transmission circuit 11. In other words, when the shutdown time is equal to or greater than the preset time, it means that the power parameter of the firstpower transmission circuit 11 may have dropped to a preset value, and/or the temperature value of the firstpower transmission circuit 11 has dropped to a preset temperature. Therefore, thecontrol device 14 turns on the firstpower transmission circuit 11 so that the firstpower transmission circuit 11 can receive power from the power source A1 again and output power to the electronic device.

據此，根據以上一或多個實施例的電源保護方法及系統可在電力傳輸電路面臨異常條件時使電力傳輸電路能夠迅速恢復電源供應裝置的正常工作狀態，以提高整體系統的穩定性、安全性及相容性。Accordingly, the power protection method and system according to one or more of the above embodiments can enable the power transmission circuit to quickly restore the normal working state of the power supply device when the power transmission circuit faces abnormal conditions, so as to improve the stability, safety and compatibility of the overall system.

請一併參考圖1及圖3，其中圖3係依據本發明一實施例所繪示的維持電力傳輸電路的輸出電壓的流程圖。圖3所示的步驟S203可執行在圖2之步驟S103的判斷結果為「是」之後及步驟S105之前。如圖3所示，維持電力傳輸電路的輸出電壓包括：步驟S201：判斷電力參數大於預設值；步驟S203：判斷導通電路的輸出電壓是否不小於預設電壓；當步驟S203的判斷結果為「是」時，執行步驟S205：計時對應電路被關斷的關斷時間；以及當步驟S203的判斷結果為「否」時，執行步驟S207：輸出警告通知。步驟S201可視為圖2之步驟S103的判斷結果為「是」的情況，步驟S205可與圖2的步驟S107相同，故以下不再贅述步驟S201及步驟S205的內容。Please refer to FIG. 1 and FIG. 3 , wherein FIG. 3 is a flowchart of maintaining the output voltage of the power transmission circuit according to an embodiment of the present invention. Step S203 shown in FIG. 3 can be executed after the judgment result of step S103 in FIG. 2 is "yes" and before step S105. As shown in FIG. 3 , maintaining the output voltage of the power transmission circuit includes: step S201: determining whether the power parameter is greater than a preset value; step S203: determining whether the output voltage of the conductive circuit is not less than a preset voltage; when the determination result of step S203 is “yes”, executing step S205: timing the shutdown time of the corresponding circuit being shut down; and when the determination result of step S203 is “no”, executing step S207: outputting a warning notification. Step S201 can be regarded as the case where the judgment result of step S103 in FIG. 2 is "yes", and step S205 can be the same as step S107 in FIG. 2, so the contents of step S201 and step S205 will not be described in detail below.

於步驟S203，控制裝置14判斷所述多個電力傳輸電路中除了所述一或多個對應電路外的一或多個導通電路的輸出電壓的總和是否不小於預設電壓。預設電壓可為維持電子裝置運作時所需的最小電壓。導通電路為電力傳輸電路中電力參數不大於對應的預設值的一或多個電力傳輸電路。舉例而言，預設電壓可為11.4伏特，但本發明不予以限制。以上述第一電力傳輸電路11為對應電路為例，第二電力傳輸電路12為導通電路。In step S203, thecontrol device 14 determines whether the sum of the output voltages of one or more conductive circuits in the plurality of power transmission circuits other than the one or more corresponding circuits is not less than a preset voltage. The preset voltage may be the minimum voltage required to maintain the operation of the electronic device. The conductive circuit is one or more power transmission circuits in the power transmission circuit whose power parameter is not greater than the corresponding preset value. For example, the preset voltage may be 11.4 volts, but the present invention is not limited thereto. Taking the firstpower transmission circuit 11 as the corresponding circuit as an example, the secondpower transmission circuit 12 is the conductive circuit.

當控制裝置14判斷第二電力傳輸電路12的輸出電壓不小於預設電壓時，表示第二電力傳輸電路12輸出的輸出電壓足夠供電子裝置運作。因此，控制裝置14可計時第一電力傳輸電路11的關斷時間，即執行圖2的步驟S107。When thecontrol device 14 determines that the output voltage of the secondpower transmission circuit 12 is not less than the preset voltage, it means that the output voltage of the secondpower transmission circuit 12 is sufficient for the electronic device to operate. Therefore, thecontrol device 14 can time the shutdown time of the firstpower transmission circuit 11, that is, execute step S107 of Figure 2.

反之，當控制裝置14判斷第二電力傳輸電路12的輸出電壓小於預設電壓時，表示第二電力傳輸電路12輸出的輸出電壓不足以供電子裝置運作。因此，於步驟S207，控制裝置14可輸出警告通知至所連接之顯示器及/或雲端等，以通知使用者電力不足的狀況。On the contrary, when thecontrol device 14 determines that the output voltage of the secondpower transmission circuit 12 is less than the preset voltage, it means that the output voltage of the secondpower transmission circuit 12 is insufficient for the electronic device to operate. Therefore, in step S207, thecontrol device 14 can output a warning notification to the connected display and/or cloud to inform the user of the insufficient power condition.

透過圖3之實施例，可確保在關斷電源供應裝置中的一或多個電力傳輸電路時，不會因而造成電子裝置的運作中斷。Through the embodiment of FIG. 3 , it can be ensured that when one or more power transmission circuits in the power supply device are turned off, the operation of the electronic device will not be interrupted.

請一併參考圖1及圖4，其中圖4係依據本發明一實施例所繪示的在重啟過程中對電力傳輸電路的即時監測的流程圖。如圖4所示，在重啟過程中執行的即時監測包括：步驟S301：關斷所述電力傳輸電路中的所述一或多個對應電路；步驟S303：判斷對應所述一或多個對應電路的電力輸入的電力感測值是否大於零；當步驟S303的判斷結果為「是」時，執行步驟S305：停止計時關斷時間；以及當步驟S303的判斷結果為「否」時，執行步驟S307：計時對應電路被關斷的關斷時間。步驟S301可與圖2的步驟S105相同，步驟S307可與圖2的步驟S107相同，故不於此贅述。Please refer to FIG. 1 and FIG. 4 , wherein FIG. 4 is a flow chart of real-time monitoring of a power transmission circuit during a restart process according to an embodiment of the present invention. As shown in FIG. 4 , the real-time monitoring performed during the restart process includes: step S301: shutting down the one or more corresponding circuits in the power transmission circuit; step S303: determining whether the power sensing value of the power input corresponding to the one or more corresponding circuits is greater than zero; when the determination result of step S303 is “yes”, executing step S305: stopping the timing of the shutdown time; and when the determination result of step S303 is “no”, executing step S307: timing the shutdown time when the corresponding circuit is shut down. Step S301 may be the same as step S105 in FIG. 2 , and step S307 may be the same as step S107 in FIG. 2 , and thus will not be described in detail herein.

於步驟S303，控制裝置14可接收電源偵測器13對第一電力傳輸電路11（對應電路）的輸出端的感測結果，以判斷的第一電力傳輸電路11的電力感測值是否大於零。In step S303, thecontrol device 14 may receive the sensing result of the output terminal of the first power transmission circuit 11 (corresponding circuit) from thepower detector 13 to determine whether the power sensing value of the firstpower transmission circuit 11 is greater than zero.

當第一電力傳輸電路11的電力感測值大於零時，表示即使在關斷後，仍有電力從第一電力傳輸電路11流出。因此，於步驟S305，控制裝置停止計時關斷時間，以終止重啟程序。When the power sensing value of the firstpower transmission circuit 11 is greater than zero, it means that even after being turned off, power still flows out of the firstpower transmission circuit 11. Therefore, in step S305, the control device stops counting the turn-off time to terminate the restart procedure.

當第一電力傳輸電路11的電力感測值不大於零（即等於零）時，表示無電力從關斷後的第一電力傳輸電路11流出。因此，控制裝置14可執行步驟S307，以繼續計時關斷時間。When the power sensing value of the firstpower transmission circuit 11 is not greater than zero (ie equal to zero), it indicates that no power flows out of the firstpower transmission circuit 11 after being turned off. Therefore, thecontrol device 14 can execute step S307 to continue counting the turn-off time.

透過圖4的實施例，可確保在執行重啟程序的過程中可避免持續性的電力輸入/輸出，而對電力傳輸電路造成更嚴重的傷害。Through the embodiment of FIG. 4 , it is ensured that continuous power input/output can be avoided during the restart process, thereby preventing the power transmission circuit from being more seriously damaged.

請一併參考圖1及圖5，其中圖5係依據本發明一實施例所繪示的針對電力傳輸線路的多次重啟的保護機制。需先說明的是，在圖5的實施例中，關斷對應電路可以是執行於所述一或多個對應電路的電力參數大於各自對應的預設值的持續時間落於暫態時間範圍內時，且此述的電力參數可以是指對應電路的輸出端的電力參數，其中暫態時間範圍例如為1毫秒，但本發明不予以限制。換言之，控制裝置14可以是在對應電路的輸出端的電力參數指示有突波的狀況時，關斷對應電路。Please refer to FIG. 1 and FIG. 5 , wherein FIG. 5 is a protection mechanism for multiple restarts of a power transmission line according to an embodiment of the present invention. It should be noted that in the embodiment of FIG. 5 , shutting down the corresponding circuit may be performed when the duration of the power parameter of the one or more corresponding circuits being greater than the corresponding preset value falls within the transient time range, and the power parameter mentioned here may refer to the power parameter of the output end of the corresponding circuit, wherein the transient time range is, for example, 1 millisecond, but the present invention is not limited thereto. In other words, thecontrol device 14 may shut down the corresponding circuit when the power parameter of the output end of the corresponding circuit indicates a surge condition.

如圖5所示，保護機制可包括：步驟S401：關斷所述電力傳輸電路中的所述一或多個對應電路；步驟S403：計數關斷次數；步驟S405：判斷關斷次數是否不小於預設次數；當步驟S405的判斷結果為「是」時，執行步驟S407：關斷電力傳輸電路與電源之間的連接；以及當步驟S405的判斷結果為「否」時，執行步驟S409：取得電力傳輸電路的電力參數。步驟S401可與圖2的步驟S105相同，步驟S409可與圖2的步驟S101相同，故不於此贅述。As shown in FIG5 , the protection mechanism may include: step S401: shutting down the one or more corresponding circuits in the power transmission circuit; step S403: counting the number of shut-downs; step S405: determining whether the number of shut-downs is not less than a preset number; when the determination result of step S405 is “yes”, executing step S407: shutting down the connection between the power transmission circuit and the power source; and when the determination result of step S405 is “no”, executing step S409: obtaining the power parameters of the power transmission circuit. Step S401 may be the same as step S105 in FIG. 2 , and step S409 may be the same as step S101 in FIG. 2 , and thus will not be described in detail herein.

在關斷第一電力傳輸電路11後，於步驟S403，控制裝置14於關斷次數加1。具體而言，關斷次數的初始值可為0，且控制裝置14可每經過預設時段便歸零關斷次數，其中所述預設時段可為10分鐘、1小時或一天等，本發明不予以限制。換言之，用於執行步驟S405的關斷次數可為在預設時段中累計的關斷次數。並且，控制裝置14可於判斷第一電力傳輸電路11及第二電力傳輸電路12中的至少一者的電力參數大於預設值時，便於關斷次數加1。After the firstpower transmission circuit 11 is turned off, in step S403, thecontrol device 14 adds 1 to the number of times of turning off. Specifically, the initial value of the number of times of turning off can be 0, and thecontrol device 14 can reset the number of times of turning off to zero after each preset period of time, wherein the preset period of time can be 10 minutes, 1 hour or a day, etc., and the present invention is not limited thereto. In other words, the number of times of turning off for executing step S405 can be the number of times of turning off accumulated in the preset period of time. In addition, thecontrol device 14 can add 1 to the number of times of turning off when it is determined that the power parameter of at least one of the firstpower transmission circuit 11 and the secondpower transmission circuit 12 is greater than the preset value.

於步驟S405，控制裝置14判斷關斷次數是否不小於預設次數，其中預設次數例如為5次，但本發明不予以限制。當控制裝置14判斷關斷次數不小於預設次數時，表示經過多次重啟操作後，第一電力傳輸電路11可能已損壞，而導致第一電力傳輸電路11的電力參數經過多次重啟後仍不穩定。因此，於步驟S407，控制裝置14關斷電源A1與第一電力傳輸電路11以及第二電力傳輸電路12之間的連接。換言之，控制裝置14關斷電源A1與所有電力傳輸電路之間的連接，以確保電子裝置不會因電源供應裝置的問題而受損。In step S405, thecontrol device 14 determines whether the number of shutdown times is not less than a preset number of times, wherein the preset number of times is, for example, 5 times, but the present invention is not limited thereto. When thecontrol device 14 determines that the number of shutdown times is not less than the preset number of times, it indicates that after multiple restart operations, the firstpower transmission circuit 11 may have been damaged, resulting in the power parameters of the firstpower transmission circuit 11 being unstable after multiple restarts. Therefore, in step S407, thecontrol device 14 shuts down the connection between the power source A1 and the firstpower transmission circuit 11 and the secondpower transmission circuit 12. In other words, thecontrol device 14 shuts off the connection between the power source A1 and all power transmission circuits to ensure that the electronic device will not be damaged due to problems with the power supply device.

當控制裝置14判斷關斷次數小於預設次數時，控制裝置14可繼續監控第一電力傳輸電路11以及第二電力傳輸電路12的電力參數，即再次執行圖1的步驟S101。When thecontrol device 14 determines that the number of shutdown times is less than the preset number of times, thecontrol device 14 may continue to monitor the power parameters of the firstpower transmission circuit 11 and the secondpower transmission circuit 12, that is, execute step S101 of FIG. 1 again.

綜上所述，根據以上一或多個實施例的電源保護方法及系統可在電力傳輸電路面臨異常條件時使電力傳輸電路能夠迅速恢復電源供應裝置的正常工作狀態，以提高整體系統的穩定性、安全性及相容性。透過維持電力傳輸電路的輸出電壓的機制，可確保在關斷電源供應裝置中的一或多個電力傳輸電路時，不會因而造成電子裝置的運作中斷。透過在重啟過程中對電力傳輸電路進行即時監測的機制，可確保在執行重啟程序的過程中可避免持續性的電力輸入/輸出，而對電力傳輸電路造成更嚴重的傷害。並且，透過在關斷次數過高而直接切斷電力傳輸電路與電源之間的連接的機制，可確保電子裝置不會因電源供應裝置問題而受損。In summary, the power protection method and system according to one or more of the above embodiments can enable the power transmission circuit to quickly restore the normal working state of the power supply device when the power transmission circuit faces abnormal conditions, so as to improve the stability, safety and compatibility of the overall system. By maintaining the output voltage of the power transmission circuit, it can be ensured that when one or more power transmission circuits in the power supply device are turned off, the operation of the electronic device will not be interrupted. By monitoring the power transmission circuit in real time during the restart process, it can be ensured that continuous power input/output can be avoided during the execution of the restart procedure, which can cause more serious damage to the power transmission circuit. Furthermore, by directly cutting off the connection between the power transmission circuit and the power source when the shutdown times are too high, it can be ensured that the electronic device will not be damaged due to problems with the power supply device.
