該主控晶片U3與伺服器S1、S2、S3、S4電性連接，當該伺服器S1、S2、S3、S4工作時，其會向主控晶片U3發送一PRESENT訊號。該主控晶片U3包括訊號接收端子DE1、DE2、DE3、DE4、資料傳輸端子SDA、訊號控制端子CT1、CT2、CT3、CT4及訊號輸出端子OUT。該訊號接收端子DE1、DE2、DE3、DE4分別與伺服器S1、S2、S3、S4電性連接，以接收PRESENT訊號。該資料傳輸端子SDA藉由資料傳輸引腳DATA與多工器U2電性連接，以依據接收到的PRESENT訊號控制多工器U2選通對應的伺服器S1、S2、S3、S4。該訊號控制端子CT1、CT2、CT3、CT4分別藉由一個指示燈L接地，當伺服器S1、S2、S3、S4中的一個或多個被選通時，該主控晶片U3控制對應的訊號控制端子CT1、CT2、CT3、CT4輸出高電平，以點亮對應的指示燈L，進而指示相應的伺服器已經被選通。例如，當伺服器S1被選通時，該訊號控制端子CT1輸出高電平以點亮對應的指示燈L。另外，當伺服器S1、S2、S3、S4被選通時，其藉由多工器U2與主控晶片U3建立通訊，以依據內部設備的運行狀況向主控晶片U3傳送一風扇轉速需求資訊。該訊號輸出端子OUT與風扇控制器U4電性連接，該主控晶片U3處理所述風扇轉速需求資訊，並獲得一組風扇轉速資料，同時藉由訊號輸出端子OUT傳送至風扇控制器U4。The master wafer U3 is electrically connected to the servers S1, S2, S3, and S4. When the servers S1, S2, S3, and S4 are in operation, they send a PRESENT signal to the master wafer U3. The main control chip U3 includes signal receiving terminals DE1, DE2, DE3, DE4, data transmission terminal SDA, signal control terminals CT1, CT2, CT3, CT4 and signal output terminal OUT. The signal receiving terminals DE1, DE2, DE3, and DE4 are electrically connected to the servers S1, S2, S3, and S4, respectively, to receive the PRESENT signal. The data transmission terminal SDA is electrically connected to the multiplexer U2 via the data transmission pin DATA, and controls the servers S1, S2, S3, and S4 corresponding to the multiplexer U2 strobe according to the received PRESENT signal. The signal control terminals CT1, CT2, CT3, and CT4 are grounded by an indicator light L, respectively. When one or more of the servers S1, S2, S3, and S4 are gated, the master control chip U3 controls the corresponding signal. The control terminals CT1, CT2, CT3, and CT4 output a high level to illuminate the corresponding indicator light L, thereby indicating that the corresponding server has been strobed. For example, when the server S1 is strobed, the signal control terminal CT1 outputs a high level to illuminate the corresponding indicator light L. In addition, when the servers S1, S2, S3, and S4 are strobed, they establish communication with the master wafer U3 by the multiplexer U2 to transmit a fan speed demand information to the master wafer U3 according to the operating condition of the internal device. . The signal output terminal OUT is electrically connected to the fan controller U4. The master control chip U3 processes the fan speed demand information, and obtains a set of fan speed data, and transmits the signal to the fan controller U4 through the signal output terminal OUT.
該風扇控制器U4分別與風扇FAN1、FAN2、FAN3電性連接，並依據風扇轉速資料控制風扇FAN1、FAN2、FAN3按照風扇轉速資料對應的速率轉動。同時該風扇控制器U4還接收風扇FAN1、FAN2、FAN3回饋的轉速，並與一預設的轉速範圍比對，若風扇FAN1、FAN2、FAN3回饋的轉速在預設的轉速範圍內，則無需調節風扇FAN1、FAN2、FAN3的轉速；若風扇FAN1、FAN2、FAN3回饋的轉速未在預設的轉速範圍內，則風扇控制器U4將自動調節風扇FAN1、FAN2、FAN3的轉速。The fan controller U4 is electrically connected to the fans FAN1, FAN2, and FAN3, respectively, and controls the fans FAN1, FAN2, and FAN3 to rotate at a rate corresponding to the fan speed data according to the fan speed data. At the same time, the fan controller U4 also receives the speed fed back by the fans FAN1, FAN2, and FAN3, and compares with a preset speed range. If the speed fed back by the fans FAN1, FAN2, and FAN3 is within a preset speed range, no adjustment is needed. The rotational speeds of the fans FAN1, FAN2, and FAN3; if the rotational speeds fed back by the fans FAN1, FAN2, and FAN3 are not within the preset rotational speed range, the fan controller U4 will automatically adjust the rotational speeds of the fans FAN1, FAN2, and FAN3.
下面進一步說明該伺服器風扇控制系統的工作原理，例如，當伺服器S1及S4運行時，首先該電源輸入連接器CON1及CON4分別從伺服器S1及S4獲取12V的電壓，此時，該第一電壓輸出端O1、第二電壓輸出端O2及第三電壓輸出端O3均可輸出電壓，相應的控制電路15的場效應管Q導通，多個場效應管Q的源極S均輸出約為12V的電壓，以為風扇FAN1、FAN2、FAN3供電。The working principle of the servo fan control system is further described below. For example, when the servers S1 and S4 are running, the power input connectors CON1 and CON4 first obtain 12V voltages from the servers S1 and S4, respectively. A voltage output terminal O1, a second voltage output terminal O2, and a third voltage output terminal O3 can output voltages, and the FET Q of the corresponding control circuit 15 is turned on, and the source S of the plurality of FETs Q outputs about The voltage of 12V is used to supply power to fans FAN1, FAN2, and FAN3.
另一方面，當伺服器S1及S4運行時，伺服器S1及S4均向主控晶片U3發送PRESENT訊號。該主控晶片U3依據接收到的PRESENT訊號控制多工器U2選通伺服器S1及S4，如此，該伺服器S1及S4與主控晶片U3建立通訊，伺服器S1及S4隨即向主控晶片U3傳送風扇轉速需求資訊。該主控晶片U3處理所述風扇轉速需求資訊，並獲得一組風扇轉速資料。其後，該風扇控制器U4依據風扇轉速資料控制風扇FAN1、FAN2、FAN3轉動。如此，藉由風扇FAN1、FAN2、FAN3可向伺服器機架內部吹風以調節伺服器機架內部的溫度，從而到達散熱的目的。On the other hand, when the servers S1 and S4 are running, the servers S1 and S4 both send the PRESENT signal to the master wafer U3. The master control chip U3 controls the multiplexer U2 strobe servers S1 and S4 according to the received PRESENT signal, so that the servers S1 and S4 establish communication with the master control chip U3, and the servers S1 and S4 then go to the master control chip. U3 transmits fan speed demand information. The master wafer U3 processes the fan speed demand information and obtains a set of fan speed data. Thereafter, the fan controller U4 controls the rotation of the fans FAN1, FAN2, and FAN3 in accordance with the fan speed data. In this way, the fans FAN1, FAN2, and FAN3 can be blown to the inside of the server rack to adjust the temperature inside the server rack, thereby achieving the purpose of heat dissipation.
本發明的伺服器風扇控制系統的風扇設置在伺服器機架外部，藉由風扇供電單元10為風扇提供電壓，並藉由風扇轉速控制單元30控制風扇的轉速。由於風扇供電單元10可以在任意一個或多個伺服器運行時即為風扇提供電壓，使得風扇轉動以調節伺服器機架內部的溫度。同時，由於風扇設置在伺服器機架外部，並採取共用風扇的方式解決系統的散熱問題，因此本發明的伺服器風扇控制系統可有效降低耗電量，同時便於維護。The fan of the servo fan control system of the present invention is disposed outside the server rack, and the fan power supply unit 10 supplies voltage to the fan, and the fan speed control unit 30 controls the rotation speed of the fan. Since the fan power supply unit 10 can supply a voltage to the fan when any one or more of the servers are running, the fan rotates to adjust the temperature inside the servo rack. At the same time, since the fan is disposed outside the server rack and the fan is used to solve the heat dissipation problem of the system, the server fan control system of the present invention can effectively reduce the power consumption and is convenient for maintenance.
