Description

遠端控制方法
本發明是有關於一種遠端控制方法,尤指一種可達到方法簡單以及有效降低成本之遠端控制方法。
按,一般欲進行遠端操作作業時,通常會裝設有KVM切換器,進而透過該KVM切換器讓該控制端於遠端操作該被控制端。 然,以習用之KVM切換器而言,其使用時必須透過網路進行連線,一旦網路中斷便無法進行操作;此外,習用之KVM切換器不但建置程序較為繁複,亦有機器設備與建置成本皆較高等缺失。 為解決習用之種種缺失,本案之發明人特潛心研究,開發出一種遠端控制方法,以有效改善習用之缺點。
本發明之主要目的係在於,可透過該影像擷取機構之連接,使該控制端可操作該被控制端,而不須透過切換器與網路,可達到方法簡單以及有效降低成本之功效。 為達上述之目的,本發明係一種遠端控制方法,其包含有下列步驟: 步驟一:設置一控制端,該控制端具有一操作介面及一第一連接埠。 步驟二:連接一影像擷取機構至該控制端,該影像擷取機構包括一USB連接器、一處理器及至少一USB-C連接器,該USB連接器連接該第一連接埠,該處理器連接該USB連接器與該USB-C連接器。 步驟三:連接至少一被控制端至該影像擷取機構,該被控制端具有一第二連接埠,該第二連接埠連接該USB-C連接器。 步驟四:由該操作介面輸入切換之控制訊號,藉由該第一連接埠將控制訊號傳輸至該USB連接器,並經該處理器進行訊號之處理轉換後,由該USB-C連接器將控制訊號透過該第二連接埠傳輸至該被控制端,使該控制端與該被控制端進行連線溝通,進而由該操作介面操作該被控制端。 於上述之遠端控制方法中,該控制端為個人電腦或筆記型電腦。 於上述之遠端控制方法中,該操作介面為一鍵盤、一滑鼠或其組合。 於上述之遠端控制方法中,該第一連接埠為USB 2.0連接器或USB 3.0連接器。 於上述之遠端控制方法中,該USB連接器為USB-C連接器或USB 3.0連接器。 於上述之遠端控制方法中,該被控制端為個人電腦、筆記型電腦或伺服器。 於上述之遠端控制方法中,該第二連接埠為HDMI連接器或Display Port連接器。 於上述之遠端控制方法中,該USB-C連接器內含USB 2.0連接器。 於上述之遠端控制方法中,該第一連接埠與該USB連接器藉由一第一傳輸介面進行連接。 於上述之遠端控制方法中,該第二連接埠與該USB-C連接器藉由一第二傳輸介面進行連接。
