在以下所列舉的各實施例中，將以相同的標號代表相同或相似的元件或組件。In the various embodiments listed below, the same or similar elements or components will be denoted by the same reference numerals.

第1圖為依據本發明之一實施例之控制裝置的示意圖。在本實施例中，控制裝置100可以是微控制器(micro controller unit, MCU)或其他合適的控制器，但本發明實施例不限於此。請參考第1圖，控制裝置100可以包括偵測單元110、控制單元120、儲存單元130、時鐘源單元140與多個信號傳輸單元150_1~150_N，其中N為大於1的正整數。Fig. 1 is a schematic diagram of a control device according to an embodiment of the present invention. In this embodiment, the control device 100 may be a microcontroller (micro controller unit, MCU) or other suitable controllers, but the embodiment of the present invention is not limited thereto. Please refer to FIG. 1 , the control device 100 may include a detection unit 110 , a control unit 120 , a storage unit 130 , a clock source unit 140 and a plurality of signal transmission units 150_1 - 150_N, where N is a positive integer greater than 1.

偵測單元110偵測電壓信號，以產生偵測信號。也就是說，偵測單元110可以偵測電壓信號，並產生對應上述電壓信號之電壓值的偵測信號。在本實施例中，上述電壓信號可以是工作電壓，但本發明實施例不限於此。The detection unit 110 detects the voltage signal to generate a detection signal. That is to say, the detection unit 110 can detect the voltage signal and generate a detection signal corresponding to the voltage value of the voltage signal. In this embodiment, the above-mentioned voltage signal may be an operating voltage, but this embodiment of the present invention is not limited thereto.

控制單元120耦接偵測單元110。控制單元120可以接收偵測單元110所產生的偵測信號，並依據偵測信號，產生指示旗標、電壓資訊、第一控制信號與多個第二控制信號至少其一。The control unit 120 is coupled to the detection unit 110 . The control unit 120 can receive the detection signal generated by the detection unit 110, and generate at least one of an indication flag, voltage information, a first control signal, and a plurality of second control signals according to the detection signal.

舉例來說，當控制單元120接收到偵測單元110所產生的偵測信號時，控制單元120可以將偵測信號的電壓值與一預設電壓值進行比較，以判斷偵測信號的電壓值是否大於預設電壓值，進而確定控制裝置100是否處於過電壓狀態。在本實施例中，上述預設電壓值例如為8V、9V、15V等，但本發明實施例不限於此。使用者可視其需求調整預設電壓值的大小，都可達到相同的技術效果。For example, when the control unit 120 receives the detection signal generated by the detection unit 110, the control unit 120 can compare the voltage value of the detection signal with a preset voltage value to determine the voltage value of the detection signal Whether it is greater than the preset voltage value, and then determine whether the control device 100 is in an overvoltage state. In this embodiment, the preset voltage value is, for example, 8V, 9V, 15V, etc., but the embodiment of the present invention is not limited thereto. Users can adjust the preset voltage value according to their needs, and the same technical effect can be achieved.

進一步來說，當控制單元120判斷偵測信號的電壓值未大於預設電壓值(例如偵測信號的電壓值小於8V、9V、15V)時，控制單元120可以確定控制裝置100未發生過電壓的情況，則控制單元120會產生例如低邏輯準位的指示旗標、低邏輯準位的第一控制信號與低邏輯準位的多個第二控制信號至少其一，且不會產生電壓資訊。接著，控制單元120會持續接收偵測信號，以判斷偵測信號的電壓值是否大於預設電壓值，進而確定控制裝置100是否處於過電壓狀態。Further, when the control unit 120 judges that the voltage value of the detection signal is not greater than the preset voltage value (for example, the voltage value of the detection signal is less than 8V, 9V, 15V), the control unit 120 can determine that the control device 100 does not have an overvoltage case, the control unit 120 will generate at least one of, for example, an indication flag of a low logic level, a first control signal of a low logic level, and a plurality of second control signals of a low logic level, and will not generate voltage information . Next, the control unit 120 will continue to receive the detection signal to determine whether the voltage value of the detection signal is greater than a preset voltage value, and then determine whether the control device 100 is in an overvoltage state.

當控制單元120判斷偵測信號的電壓值大於預設電壓值(例如偵測信號的電壓值大於8V、9V、15V)時，控制單元120可以確定控制裝置100處於過電壓狀態，則控制單元120會產生例如高邏輯準位的指示旗標、電壓資訊、高邏輯準位的第一控制信號與高邏輯準位的多個第二控制信號至少其一，以便進行後續的操作。When the control unit 120 judges that the voltage value of the detection signal is greater than the preset voltage value (for example, the voltage value of the detection signal is greater than 8V, 9V, 15V), the control unit 120 can determine that the control device 100 is in an overvoltage state, and the control unit 120 For example, at least one of a high logic level indication flag, voltage information, a high logic level first control signal, and a plurality of high logic level second control signals is generated for subsequent operations.

在本實施例中，上述指示旗標可以指示控制裝置100是否處於過電壓狀態。舉例來說，當指示旗標為高邏輯準位時，表示控制裝置100處於過電壓狀態；當指示旗標為低邏輯準位時，表示控制裝置100未處於過電壓狀態。另外，上述電壓資訊可以至少包括過電壓的起始時間、過電壓的電壓值、過電壓的產生次數。此外，上述過電壓的產生次數可以對應指示旗標為高邏輯準位時的次數。也就是說，控制單元120可以對每一次所產生之高邏輯準位的指示旗標進行累加，並設置於電壓資訊中，以便記錄過電壓的產生次數。In this embodiment, the above indication flag may indicate whether the control device 100 is in an overvoltage state. For example, when the indicating flag is at a high logic level, it means that the control device 100 is in an overvoltage state; when the indicating flag is at a low logic level, it means that the control device 100 is not in an overvoltage state. In addition, the above voltage information may at least include the start time of the overvoltage, the voltage value of the overvoltage, and the generation times of the overvoltage. In addition, the number of occurrences of the above-mentioned overvoltage may correspond to the number of times when the indication flag is at a high logic level. That is to say, the control unit 120 can accumulate the indication flag of the high logic level every time it is generated, and set it in the voltage information, so as to record the generation times of the overvoltage.

儲存單元130耦接控制單元120。儲存單元130可以接收並儲存指示旗標與電壓資訊。也就是說，控制單元120所產生的指示旗標與電壓資訊可以傳送並儲存至儲存單元130。在本實施例中，儲存單元130例如為暫存器(register)、隨機存取記憶體(random access memory, RAM)或快閃記憶體(flash memory)等，但本發明實施例不限於此。如此一來，使用者可以透過取得儲存單元130所儲存之電壓資訊，以得知控制裝置100是否處於過電壓狀態(亦即控制裝置100在過電壓狀態下使用過)，而無須將控制裝置100送回原廠進行檢測是否發生過過電壓現象，以增加使用上的便利性。The storage unit 130 is coupled to the control unit 120 . The storage unit 130 can receive and store the indication flag and voltage information. That is to say, the indication flag and voltage information generated by the control unit 120 can be transmitted and stored in the storage unit 130 . In this embodiment, the storage unit 130 is, for example, a register, a random access memory (random access memory, RAM), or a flash memory (flash memory), but the embodiment of the present invention is not limited thereto. In this way, the user can know whether the control device 100 is in an overvoltage state (that is, the control device 100 has been used in an overvoltage state) by obtaining the voltage information stored in the storage unit 130, without having to use the control device 100 Send it back to the original factory to check whether there is any overvoltage phenomenon, so as to increase the convenience of use.

時鐘源單元140耦接控制單元120。時鐘源單元140可以接收第一控制信號，並依據第一控制信號，產生第一時鐘信號或第二時鐘信號。舉例來說，當時鐘源單元140接收到例如低邏輯準位的第一控制信號，表示控制裝置100未處於過電壓狀態，時鐘源單元140會例如提供第一時鐘信號。當時鐘源單元140接收到例如高邏輯準位的第二控制信號，表示控制裝置100處於過電壓狀態，時鐘源單元140會例如提供第二時鐘信號。The clock source unit 140 is coupled to the control unit 120 . The clock source unit 140 can receive the first control signal, and generate the first clock signal or the second clock signal according to the first control signal. For example, when the clock source unit 140 receives a first control signal such as a low logic level, indicating that the control device 100 is not in an overvoltage state, the clock source unit 140 will, for example, provide a first clock signal. When the clock source unit 140 receives the second control signal such as a high logic level, indicating that the control device 100 is in an overvoltage state, the clock source unit 140 will, for example, provide a second clock signal.

在本實施例中，第一時鐘信號與第二時鐘信號的頻率不同。舉例來說，第一時鐘信號例如為控制裝置100正常運作時的時鐘信號，第二時鐘信號例如為控制裝置100處於過電壓狀態(即耐高壓)的時鐘信號。如此一來，當控制裝置100處於過電壓狀態時，控制裝置100仍可在過電壓狀態下持續工作，而不會導致裝置裝置100當機的情況發生，以增加使用上的便利性。另外，時鐘源單元140可以是一振盪電路，例如RC振盪電路、晶體振盪電路等，但本發明實施例不限於此。In this embodiment, the frequencies of the first clock signal and the second clock signal are different. For example, the first clock signal is, for example, a clock signal when the control device 100 is operating normally, and the second clock signal is, for example, a clock signal when the control device 100 is in an overvoltage state (ie, withstands high voltage). In this way, when the control device 100 is in the overvoltage state, the control device 100 can continue to work in the overvoltage state without causing the device 100 to crash, thereby increasing the convenience in use. In addition, the clock source unit 140 may be an oscillating circuit, such as an RC oscillating circuit, a crystal oscillating circuit, etc., but the embodiment of the present invention is not limited thereto.

信號傳輸單元150_1~150_N耦接控制單元120。信號傳輸單元150_1~150_N可以接收第二控制信號，並依據第二控制信號，傳輸或不傳輸多個功能信號。舉例來說，當信號傳輸單元150_1~150_N接收到例如低邏輯準位的第二控制信號，表示控制裝置100未處於過電壓狀態，信號傳輸單元150_1~150_N例如會傳輸上述功能信號。當信號傳輸單元150_1~150_N接收到例如高邏輯準位的第二控制信號，表示控制裝置100處於過電壓狀態，信號傳輸單元150_1~150_N例如不會提供功能信號，亦即信號傳輸單元150_1~150_N停止運作。The signal transmission units 150_1 - 150_N are coupled to the control unit 120 . The signal transmission units 150_1 - 150_N can receive the second control signal, and transmit or not transmit a plurality of function signals according to the second control signal. For example, when the signal transmission units 150_1 - 150_N receive the second control signal of eg low logic level, indicating that the control device 100 is not in the overvoltage state, the signal transmission units 150_1 - 150_N, for example, transmit the above function signal. When the signal transmission units 150_1~150_N receive the second control signal of eg a high logic level, indicating that the control device 100 is in an overvoltage state, the signal transmission units 150_1~150_N, for example, will not provide functional signals, that is, the signal transmission units 150_1~150_N stop working.

在本實施例中，上述信號傳輸單元150_1~150_N例如為不能耐高壓的工作元件。透過控制單元120於控制裝置100處於過電壓狀態時停止信號傳輸單元150_1~150_N的運作，可以提高工作元件(即信號傳輸單元150_1~150_N)的可靠度。舉例來說，假設上述工作元件可以在過電壓下持續30秒才會故障，並且於控制裝置100處於過電壓狀態時停止工作元件的運作，使得工作元件耐受高壓的時間例如為0.1秒。如此一來，可以使得工作元件之耐受高壓的次數為300次，且工作元件沒有連續地耐受高壓，以便提高工作元件的可靠度。In this embodiment, the signal transmission units 150_1 - 150_N are, for example, working elements that cannot withstand high voltage. Through the control unit 120 stopping the operation of the signal transmission units 150_1 - 150_N when the control device 100 is in the overvoltage state, the reliability of the working elements (ie, the signal transmission units 150_1 - 150_N) can be improved. For example, it is assumed that the above-mentioned working element can last 30 seconds under the overvoltage before failure, and the operation of the working element is stopped when the control device 100 is in the overvoltage state, so that the time for the working element to withstand high voltage is, for example, 0.1 second. In this way, the number of times the working element can withstand high voltage is 300 times, and the working element does not withstand high voltage continuously, so as to improve the reliability of the working element.

進一步來說，信號傳輸單元150_1~150_N可以是類比數位轉換器(analog-to-digital converter, ADC)、數位類比轉換器(digital -to-analog converter, DAC)、放大器(operational amplifier, OPA)等，並且上述功能信號可以包括類比轉數位功能信號、數位轉類比功能信號、放大功能信號等，但本發明實施例不限於此。Further, the signal transmission units 150_1~150_N may be analog-to-digital converters (analog-to-digital converter, ADC), digital-to-analog converters (digital-to-analog converter, DAC), amplifiers (operational amplifier, OPA), etc. , and the above-mentioned function signal may include an analog-to-digital function signal, a digital-to-analog function signal, an amplification function signal, etc., but the embodiment of the present invention is not limited thereto.

在一些實施例中，在控制單元120產生高邏輯準位的指示旗標、電壓資訊至儲存單元130後，表示控制單元120確定控制裝置100處於過電壓狀態，則控制單元120可以再次接收偵測單元110的偵測信號，並判斷偵測信號的電壓值是否大於預設電壓值。In some embodiments, after the control unit 120 generates an indication flag of a high logic level and the voltage information to the storage unit 130, indicating that the control unit 120 determines that the control device 100 is in an overvoltage state, the control unit 120 can receive the detection again. The detection signal of the unit 110 is used to determine whether the voltage value of the detection signal is greater than a preset voltage value.

當控制單元120判斷偵測信號的電壓值大於預設電壓值時，表示控制裝置100仍處於過電壓狀態，則控制單元120會持續接收偵測單元110的偵測信號，並判斷偵測信號的電壓值是否大於預設電壓值，直到控制單元120判斷偵測信號的電壓值未大於預設電壓值為止。When the control unit 120 judges that the voltage value of the detection signal is greater than the preset voltage value, it means that the control device 100 is still in the overvoltage state, and the control unit 120 will continue to receive the detection signal from the detection unit 110, and judge the detection signal. Whether the voltage value is greater than the preset voltage value, until the control unit 120 determines that the voltage value of the detection signal is not greater than the preset voltage value.

另外，當控制單元120判斷偵測信號的電壓值未大於預設電壓值時，表示控制裝置100回復到未處於過電壓狀態，則控制單元120可以產生低邏輯準位的指示旗標至儲存單元130，以將高邏輯準位的指示旗標清除，進而指示控制裝置100未處於過電壓狀態。另外，控制單元120也可以產生例如包括過電壓的結束時間的電壓資訊至儲存單元130，以便記錄過電壓的結束時間。In addition, when the control unit 120 judges that the voltage value of the detection signal is not greater than the preset voltage value, it means that the control device 100 is not in the overvoltage state, and the control unit 120 can generate an indication flag of a low logic level to the storage unit. 130 , to clear the indication flag of the high logic level, thereby indicating that the control device 100 is not in the overvoltage state. In addition, the control unit 120 may also generate, for example, voltage information including the end time of the overvoltage to the storage unit 130 so as to record the end time of the overvoltage.

在一些實施例中，在控制單元120產生高邏輯準位的第一控制信號至時鐘源單元140，使得時鐘源單元140產生第二時鐘信號後，表示控制單元120確定控制裝置100處於過電壓狀態，則控制單元120可以再次接收偵測單元110的偵測信號，並判斷偵測信號的電壓值是否大於預設電壓值。In some embodiments, after the control unit 120 generates the first control signal of a high logic level to the clock source unit 140, so that the clock source unit 140 generates the second clock signal, it means that the control unit 120 determines that the control device 100 is in an overvoltage state , the control unit 120 may receive the detection signal from the detection unit 110 again, and determine whether the voltage value of the detection signal is greater than a preset voltage value.

當控制單元120判斷偵測信號的電壓值大於預設電壓值時，表示控制裝置100仍處於過電壓狀態，則控制單元120會持續接收偵測單元110的偵測信號，並判斷偵測信號的電壓值是否大於預設電壓值，直到控制單元120判斷偵測信號的電壓值未大於預設電壓值為止。When the control unit 120 judges that the voltage value of the detection signal is greater than the preset voltage value, it means that the control device 100 is still in the overvoltage state, and the control unit 120 will continue to receive the detection signal from the detection unit 110, and judge the detection signal. Whether the voltage value is greater than the preset voltage value, until the control unit 120 determines that the voltage value of the detection signal is not greater than the preset voltage value.
