電腦往往會透過主機板連結許多周邊裝置,以進行各種應用。例如,電腦運作時通常會產生很多廢熱,因此常會配置散熱風扇以調整內部溫度,讓電腦的各種元件不會因為過熱而停止運作或損壞。藉由良好的風扇調控,可使電腦的溫度保持在正常範圍內以維持正常運作。Computers often connect many peripheral devices through the motherboard for various applications. For example, a computer usually generates a lot of waste heat during operation, so a cooling fan is often equipped to adjust the internal temperature, so that various components of the computer will not stop functioning or be damaged due to overheating. With good fan control, the temperature of the computer can be kept within the normal range to maintain normal operation.

然而,由於需求所趨,電腦的體積越來越縮減,且隨著處理器的運算速度提升,電腦內部的溫度也越來越高,故風扇的數量也跟著增加,且彼此的設置距離也越來越近。如此一來,將容易發生訊號線路過於靠近,而發生耦合或引起雜訊之通訊方面的問題,導致主機板無法對周邊裝置進行良好的控制。因此,如何控制電腦的周邊裝置以提高可靠性及效能實為本領域相關人員所關注的焦點。However, due to the trend of demand, the size of the computer is getting smaller and smaller, and with the increase of the computing speed of the processor, the temperature inside the computer is getting higher and higher, so the number of fans is also increasing, and the distance between them is also larger. come closer. In this way, it is easy to cause the signal lines to be too close together, which may cause coupling or communication problems that cause noise, which will result in the motherboard being unable to control the peripheral devices well. Therefore, how to control the peripheral devices of the computer to improve the reliability and performance is the focus of those in the art.

以下為上述該調變M的其中一個舉例,在本實施例中,該電腦周邊裝置20例如可以是一風扇,但本發明並不以此為限。根據本實施例的設計,該電腦周邊裝置20常態地回傳一轉速訊號S4至該電性連接埠101,例如每隔數秒鐘回傳該轉速訊號S4。該電腦周邊裝置20具有一裝置控制器203。該電性訊號S2包括一停止訊號ST。該可程式化邏輯控制器103透過該電性連接埠101傳輸該停止訊號ST至該電腦周邊裝置20後,該裝置控制器203根據該停止訊號ST停止傳送該轉速訊號S4至該控制裝置10(本實施例並不限定該電腦周邊裝置20是否改變運轉狀態)。該控制裝置10的該可程式化邏輯控制器103根據未收到該轉速訊號S4產生一風扇確認訊號S5,該風扇確認訊號S5可以包括該電腦周邊裝置20的資訊,讓該控制裝置10可以知道該電腦周邊裝置20是一具有該裝置控制器203的電腦周邊裝置;或者,代表該主機板401和該電腦周邊裝置20是否具備通訊相容性。The following is an example of the above-mentioned modulation M. In this embodiment, the computer peripheral device 20 can be, for example, a fan, but the present invention is not limited to this. According to the design of this embodiment, the computer peripheral device 20 normally returns a rotational speed signal S4 to the electrical connection port 101 , for example, returns the rotational speed signal S4 every several seconds. The computer peripheral device 20 has a device controller 203 . The electrical signal S2 includes a stop signal ST. After the programmable logic controller 103 transmits the stop signal ST to the computer peripheral device 20 through the electrical connection port 101, the device controller 203 stops transmitting the rotational speed signal S4 to the control device 10 according to the stop signal ST ( This embodiment does not limit whether the computer peripheral device 20 changes the operating state). The programmable logic controller 103 of the control device 10 generates a fan confirmation signal S5 according to the failure to receive the rotational speed signal S4. The fan confirmation signal S5 may include the information of the computer peripheral device 20, so that the control device 10 can know The computer peripheral device 20 is a computer peripheral device having the device controller 203; or, it represents whether the motherboard 401 and the computer peripheral device 20 have communication compatibility.

請再參照圖1,該控制裝置10還包括一電性連接埠101c,該電性連接埠101c電性連接至一風扇F。該電性連接埠101c的結構與功能與前述該些電性連接埠101、101a、101b、101x相似。該風扇F常態地回傳一轉速訊號S4a至該電性連接埠101c。該電性連接埠101c與該風扇F間的電性訊號包括如前所述的該停止訊號ST。該可程式化邏輯控制器103透過該電性連接埠101c傳輸該停止訊號ST至該風扇F後,當該可程式化邏輯控制器103仍接收到該轉速訊號S4a時,該可程式化邏輯控制器103判定該風扇F不具有一如前所述的裝置控制器203;或者,可依此判定該風扇F是和該主機板401不具備通訊相容性(例如,該風扇F是一類比風扇),無法建立該通訊模式CM。反之,該可程式化邏輯控制器103透過該電性連接埠101c傳輸該停止訊號ST至該風扇F後,當該可程式化邏輯控制器103不再接收到該轉速訊號S4a時,該可程式化邏輯控制器103判定該風扇F具有一如前所述的裝置控制器203;或者,可依此判定該風扇F是和該主機板401具備通訊相容性(例如,該風扇F是一數位風扇),而可以建立該通訊模式CM。在本發明一實施例中,該風扇F例如也可以一不具有裝置控制器的數位風扇來實現。1 again, the control device 10 further includes an electrical connection port 101c, and the electrical connection port 101c is electrically connected to a fan F. The structure and function of the electrical connection port 101c are similar to the aforementioned electrical connection ports 101, 101a, 101b, and 101x. The fan F normally returns a rotational speed signal S4a to the electrical connection port 101c. The electrical signal between the electrical connection port 101c and the fan F includes the stop signal ST as described above. After the programmable logic controller 103 transmits the stop signal ST to the fan F through the electrical connection port 101c, when the programmable logic controller 103 still receives the rotational speed signal S4a, the programmable logic control The controller 103 determines that the fan F does not have a device controller 203 as described above; alternatively, it can be determined that the fan F does not have communication compatibility with the motherboard 401 (for example, the fan F is an analog fan ), the communication mode CM cannot be established. Conversely, after the programmable logic controller 103 transmits the stop signal ST to the fan F through the electrical connection port 101c, when the programmable logic controller 103 no longer receives the rotational speed signal S4a, the programmable logic controller 103 stops receiving the rotational speed signal S4a. The logic controller 103 determines that the fan F has a device controller 203 as described above; alternatively, it can be determined accordingly that the fan F has communication compatibility with the motherboard 401 (for example, the fan F is a digital fan), and the communication mode CM can be established. In an embodiment of the present invention, the fan F can also be implemented, for example, as a digital fan without a device controller.

On the contrary, if the device controller 203 of the computer peripheral device 20 can recognize the change of the voltage of the power E, it will generate the identification signal S3 according to the second voltage V2. In this case, it means that the computer peripheral device 20 has A device controller 203 as described above; alternatively, it can be determined that the computer peripheral device 20 and the motherboard 401 have communication compatibility, and the communication mode CM can be established.

If the device controller 203 of the computer peripheral device 20 cannot recognize the change, no corresponding feedback will be generated. In this case, it means that the computer peripheral device 20 does not have a device controller 203 as described above; or , it can be determined that the computer peripheral device 20 and the motherboard 401 do not have communication compatibility, and the communication mode CM cannot be established. On the contrary, if the device controller 203 of the computer peripheral device 20 can recognize the change, the identification signal S3 will be generated, in this case, it means that the computer peripheral device 20 has the device controller 203 as described above; Alternatively, it can be determined based on this that the computer peripheral device 20 and the motherboard 401 have communication compatibility, and the communication mode CM can be established.
