背景技术Background technique

现今的多计算机切换器(KVMswitch)产品会电性连接多台计算机主机。例如计算机主机为伺服主机或其他计算机装置。因此，伺服端业者可随时切换该多个计算机主机其中之一，并对该多个计算机主机其中之一进行资讯及系统维护。当该多个计算机主机电性连接到切换装置的端口后，切换装置通常透过开关芯片，以提供鼠标、键盘及显示器等随着该多个计算机主机其中之一切换。Today's KVM switch (KVM switch) products are electrically connected to multiple computer hosts. For example, the computer host is a server host or other computer devices. Therefore, the server provider can switch one of the plurality of computer hosts at any time, and perform information and system maintenance on one of the plurality of computer hosts. When the plurality of computer hosts are electrically connected to ports of the switching device, the switching device usually uses a switch chip to provide a mouse, a keyboard, and a monitor to be switched along with one of the plurality of computer hosts.

然而，资讯在计算机主机、切换装置及受控装置之间传输的过程中，往往容易发生讯号衰减、损失及低速的传输速率，因此造成计算机主机及受控装置之间必须受限在较短的距离内；或是低速的传输速率以确保计算机主机及受控装置之间能有效收发资讯；或是受限于电子规范而无法提供良好的传输速率；或是多计算机切换器往往无法提供更符合人性化的用户操控接口，藉此造成多计算机切换器使用上的不方便。However, in the process of transmitting information between the host computer, the switching device, and the controlled device, signal attenuation, loss, and low-speed transmission rate are often prone to occur, so the distance between the host computer and the controlled device must be limited to a short distance. or the low-speed transmission rate to ensure that the host computer and the controlled device can effectively send and receive information; or it is limited by the electronic specification and cannot provide a good transmission rate; or the KVM switch often cannot provide a more consistent The humanized user interface makes it inconvenient to use the KVM switch.
