該控制單元7電連接該溫度量測單元4、該訊號產生單元5及該電能檢測單元6，該控制單元7於該溫度量測單元4所量測的環境溫度不高於一預設溫度時，驅使該訊號產生單元5對該開關單元3輸入該驅動電壓以使該開關單元3變換至該導通狀態，該控制單元7於該溫度量測單元所量測的環境溫度高於該預設溫度時，驅使該訊號產生單元5不對該開關單元3輸入該驅動電壓以使該開關單元3變換至該斷路狀態。於本實施例中，該預設溫度為攝氏80度，但並不限於此。The control unit 7 is electrically connected to the temperature measuring unit 4, the signal generating unit 5 and the electric energy detecting unit 6, the control unit 7 when the ambient temperature measured by the temperature measuring unit 4 is not higher than a preset temperature , Driving the signal generating unit 5 to input the driving voltage to the switching unit 3 to switch the switching unit 3 to the conductive state, the ambient temperature measured by the control unit 7 in the temperature measuring unit is higher than the preset temperature At this time, the signal generating unit 5 is driven not to input the driving voltage to the switch unit 3 to switch the switch unit 3 to the open state. In this embodiment, the preset temperature is 80 degrees Celsius, but it is not limited thereto.

該收發單元8電連接該控制單元7並可對一伺服器92接收或輸出一收發訊號，輸出的該收發訊號的內容為該轉換電訊號的電壓大小、電流大小、功率大小及該開關單元3的導通狀態的至少其中一者，輸入的該收發訊號的內容為驅使該控制單元7控制該訊號產生單元5是否輸出該驅動電壓的指令。The transceiving unit 8 is electrically connected to the control unit 7 and can receive or output a transceiving signal to a server 92. The output content of the transceiving signal is the voltage magnitude, current magnitude, power magnitude of the converted electrical signal and the switching unit 3 In at least one of the on-states, the input content of the transceiving signal is an instruction for driving the control unit 7 to control whether the signal generating unit 5 outputs the driving voltage.

使用時，該太陽能板模組91會將所接收的太陽能轉換成該轉換電訊號，當該控制單元7於該溫度量測單元4所量測的環境溫度不高於攝氏80度時，驅使該訊號產生單元5對該開關單元3輸入15VDC的該驅動電壓，以使該開關單元3變換至該導通狀態，此時該轉換電訊號就能通過該輸入單元21及該開關單元3而由該輸出單元22輸出，以將電力提供給後續元件使用或進一步儲存備用。When in use, the solar panel module 91 converts the received solar energy into the converted electrical signal. When the ambient temperature measured by the control unit 7 at the temperature measurement unit 4 is not higher than 80 degrees Celsius, the The signal generating unit 5 inputs the driving voltage of 15 VDC to the switching unit 3 to switch the switching unit 3 to the conductive state, at which time the converted electrical signal can pass through the input unit 21 and the switching unit 3 to output from the output The unit 22 outputs to provide power to subsequent components for use or further storage for backup.

同時，該控制單元7能將該電能檢測單元6所檢測該轉換電訊號的電壓大小、電流大小、功率大小及該開關單元3的導通狀態透過該收發單元8所輸出的該收發訊號傳送至該伺服器92，使遠方的維運人員能根據該伺服器92所接收的該收發訊號就能得知該太陽能智慧防災斷路器的相關即時狀況。於本實施例中，該控制單元7是定期發送該收發訊號，例如是每十秒傳送一次，該收發單元8可以是以有線傳輸或是無線傳輸的型式傳送該收發訊號。At the same time, the control unit 7 can transmit the voltage magnitude, current magnitude, power magnitude of the converted electrical signal detected by the electric energy detection unit 6 and the conduction state of the switch unit 3 to the transceiving signal output by the transceiving unit 8 to the The server 92 enables remote maintenance personnel to know the real-time status of the solar smart disaster prevention circuit breaker according to the transceiver signal received by the server 92. In this embodiment, the control unit 7 periodically sends the transceiving signal, for example, every ten seconds. The transceiving unit 8 may transmit the transceiving signal in a wired or wireless transmission mode.

而當火災發生，該控制單元7於該溫度量測單元4所量測的環境溫度高於攝氏80度時，驅使該訊號產生單元5不再對該開關單元3輸入該驅動電壓以使該開關單元3變換至該斷路狀態，此時電能較大的該轉換電訊號就無法通過該開關單元3，由於直流電的正負極不再構成迴路，故不再有該轉換電訊號的產生，因此下游的線路不再有電能較大的電力經過，就能避免火災發生時因持續供應大電力所產生的擴大災害，也可避免消防救災人員觸電的意外。When a fire occurs, when the ambient temperature measured by the temperature measuring unit 4 is higher than 80 degrees Celsius, the signal generating unit 5 no longer inputs the driving voltage to the switch unit 3 to cause the switch The unit 3 changes to the open state, and at this time, the converted electrical signal with larger electric energy cannot pass through the switch unit 3. Since the positive and negative poles of the direct current no longer constitute a loop, there is no longer the generation of the converted electrical signal, so the downstream There is no longer any electricity passing through the line, which can avoid the expansion disaster caused by the continuous supply of large electricity when the fire occurs, and can also avoid the accident of electric shock for fire disaster relief personnel.

另外，當火災發生中，該控制單元7仍持續透過該收發單元8將該收發訊號傳送至該伺服器92，因此遠方的維運人員也能根據該伺服器92所接收的該收發訊號得知該開關單元3已變換至該斷路狀態，而能藉此判斷火災的發生，並採取相對應的措施。In addition, when a fire occurs, the control unit 7 continues to transmit the transceiving signal to the server 92 through the transceiving unit 8, so remote maintenance personnel can also learn from the transceiving signal received by the server 92 The switch unit 3 has been changed to the open state, so that it can judge the occurrence of fire and take corresponding measures.

要說明的是，當維運人員得知火災發生而需要停止該開關單元3，或因維修的需求而需要停止或開啟該開關單元3時，只要對該收發單元8輸入驅使該控制單元7控制該訊號產生單元5是否輸出該驅動電壓的指令，就能控制該開關單元3切換至所需要的狀態，而能確保維修人員的安全。It should be noted that when the maintenance personnel know that a fire has occurred and need to stop the switch unit 3, or need to stop or open the switch unit 3 due to maintenance needs, as long as the transceiver unit 8 is input to drive the control unit 7 to control Whether the signal generating unit 5 outputs the command of the driving voltage can control the switching unit 3 to switch to a desired state, and can ensure the safety of maintenance personnel.

要說明的是，該控制單元7還對該電能檢測單元6所檢測的該轉換電訊號於一預定時間的電壓大小進行判斷，當該預定時間內的電壓下降至一預設電壓時，該控制單元7於一延遲時間後驅使該訊號產生單元5不對該開關單元3輸入該驅動電壓以使該開關單元3變換至該斷路狀態。於本實施例中，該預定時間為3秒，該預設電壓為0VDC，該延遲時間為1秒，但並不以此為限，而可視需求進行調整，另外，在另一種實施態樣中，該預定時間為1秒，也可以是每隔該預定時間就判斷一次電壓大小，當連續三次的電壓大小是呈下降趨勢且最後一次的電壓大小是下降至該預設電壓時，驅使該使該開關單元3變換至該斷路狀態。要說明的是，當電壓下降至該預設電壓時，是代表該第一輸出端子221及該第二輸出端子222兩者之後的電路短路，因此需要該開關單元3變換至該斷路狀態以進行檢修。It should be noted that the control unit 7 also determines the voltage level of the converted electrical signal detected by the power detection unit 6 at a predetermined time. When the voltage within the predetermined time drops to a preset voltage, the control The unit 7 drives the signal generating unit 5 not to input the driving voltage to the switch unit 3 after a delay time to switch the switch unit 3 to the open state. In this embodiment, the predetermined time is 3 seconds, the preset voltage is 0 VDC, and the delay time is 1 second, but it is not limited to this, and can be adjusted according to needs. In addition, in another implementation aspect , The predetermined time is 1 second, or the voltage size can be judged once every predetermined time, when the voltage size of three consecutive times is in a downward trend and the last time the voltage size is reduced to the preset voltage, the The switching unit 3 changes to the open state. It should be noted that when the voltage drops to the preset voltage, it means that the circuit after both the first output terminal 221 and the second output terminal 222 is short-circuited, so the switching unit 3 needs to be switched to the open state for Overhaul.

如此一來，當該轉換電訊號的電壓大小產生異常的下降狀況時，可能是線路毀損或該太陽能板模組91損壞時，就能切換使該開關單元3變換至該斷路狀態，以確保整個系統的安全，並供維運人員進行維護。In this way, when the voltage level of the converted electrical signal drops abnormally, it may be that the line is damaged or the solar panel module 91 is damaged, the switch unit 3 can be switched to the open state to ensure the entire The safety of the system and maintenance for maintenance personnel.

綜上所述，藉由設置該開關單元3、該溫度量測單元4、該訊號產生單元5、該電能檢測單元6及該控制單元7，而能夠檢測是否發生火災，並於火災發生時能停止傳輸該轉換電訊號，避免災害擴大，以及於該轉換電訊號的電壓大小產生異常的下降狀況時能停止傳輸該轉換電訊號，以確保整個系統的安全，故確實能達成本發明之目的。In summary, by providing the switch unit 3, the temperature measuring unit 4, the signal generating unit 5, the electric energy detection unit 6 and the control unit 7, it is possible to detect whether a fire has occurred and when the fire occurs The transmission of the converted electrical signal is stopped to avoid the expansion of disasters, and the transmission of the converted electrical signal can be stopped when an abnormal drop in the voltage of the converted electrical signal occurs to ensure the safety of the entire system, so the purpose of the invention can indeed be achieved.

惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention.
