可程序化切换控制的计算机切换器Computer switcher with programmable switching control

技术领域technical field

本发明有关于一种计算机切换器，详细而言，有关于一种能将一控制端装置与一通用串行总线装置予以切换为控制端功能或集线端口功能的计算机切换器。The present invention relates to a computer switcher, and in detail, relates to a computer switcher capable of switching a control terminal device and a USB device to a control terminal function or a hub port function.

背景技术Background technique

计算机切换器为设置于各种控制端装置(例如鼠标、键盘、屏幕、喇叭、视讯装置等)与多个计算机装置之间，其可选择多个计算机装置其中一个，以使控制端装置可控制所选择的计算机装置，并输出计算机装置对于指令的响应。另外，计算机切换器本身亦具有通用串行总线(以下简称为USB)集线埠，以供插装USB装置。但计算机切换器上的USB装置仅能控制多个计算机装置其中之一者，或受该个计算机装置控制，不具有控制端装置控制多个计算机装置的功能。请参照图3，其为根据先前技术的计算机切换器。一般的计算机切换器300通常包含USB集线端口接口301，以供使用者可外接一个或更多个USB装置301-1到301-4(例如随身碟、鼠标、键盘、打印机等)；控制端接口302，可外接一个或更多个控制端装置302-1到302-2；一矩阵切换电路303，连接于多数个计算机接口(图3中所示为N个)305、该USB集线端口接口301、该控制端接口302；主控制电路304，连接于多数个计算机接口305及该矩阵切换电路303。计算机接口305可分别连接于一计算机装置(图中未显示)，例如个人计算机、笔记型计算机、智能型手机或是个人数字助理(PDA)。从图3中可看出，控制端装置302-1到302-2可经由矩阵切换电路303中的控制端切换接口3031而连接于主控制电路304，从而控制多数个计算机接口305，但USB装置301-1到301-4透过矩阵切换电路303而分别连接并仅传送控制信号至N个计算机接口305其中之一者，或是受该计算机接口305所连接的计算机装置控制。例如，在图3中，USB装置301-1透过矩阵切换电路303而连接于第一计算机接口305；USB装置301-2透过矩阵切换电路303而连接于第二计算机接口305。可进一步藉由矩阵切换电路303选择USB装置301-1到301-4与计算机接口305的连接关系。A computer switcher is installed between various console devices (such as mouse, keyboard, screen, speakers, video devices, etc.) and multiple computer devices. It can select one of the multiple computer devices so that the console device can the selected computer device, and output the computer device's response to the command. In addition, the computer switch itself also has a universal serial bus (hereinafter referred to as USB) hub port for plugging in USB devices. However, the USB device on the computer switch can only control one of the multiple computer devices, or be controlled by the computer device, and does not have the function of the control terminal device controlling multiple computer devices. Please refer to FIG. 3 , which is a computer switch according to the prior art. Ageneral computer switcher 300 usually includes a USBhub port interface 301 for users to connect one or more USB devices 301-1 to 301-4 (such as flash drives, mice, keyboards, printers, etc.); Theinterface 302 can be externally connected with one or more control terminal devices 302-1 to 302-2; a matrix switching circuit 303 is connected to a plurality of computer interfaces (N as shown in FIG. 3 ) 305, the USB hub port Theinterface 301 , thecontrol terminal interface 302 , and themain control circuit 304 are connected to a plurality ofcomputer interfaces 305 and the matrix switching circuit 303 . Thecomputer interface 305 can be respectively connected to a computer device (not shown in the figure), such as a personal computer, a notebook computer, a smart phone or a personal digital assistant (PDA). It can be seen from FIG. 3 that the control terminal devices 302-1 to 302-2 can be connected to themain control circuit 304 via the controlterminal switching interface 3031 in the matrix switching circuit 303, thereby controlling a plurality ofcomputer interfaces 305, but the USB device 301 - 1 to 301 - 4 are respectively connected through the matrix switching circuit 303 and only transmit the control signal to one of theN computer interfaces 305 , or be controlled by the computer device connected to thecomputer interface 305 . For example, in FIG. 3 , the USB device 301 - 1 is connected to thefirst computer interface 305 through the matrix switching circuit 303 ; the USB device 301 - 2 is connected to thesecond computer interface 305 through the matrix switching circuit 303 . The connection relationship between the USB devices 301 - 1 to 301 - 4 and thecomputer interface 305 can be further selected by the matrix switching circuit 303 .

但是以上结构无法完全满足多变的各种环境条件或是特殊操作需要。原因在于，USB集线端口接口301所连接的USB装置301-1到301-4仅具有集线端口功能，而不具有控制端功能(例如下指令予各计算机接口305、以热键于各计算机接口305之间切换等)。当计算机切换器300与控制端接口302所连接的控制端装置302-1到302-2设置于不同处时，特别会造成困难。例如当计算机切换器300设置于机房中，而各个控制端接口302所连接的控制端装置302-1到302-2经由布线而设置于控制室内时，使用者在机房内时无法实时以近端的USB装置301-1到301-4控制各个不相连接的计算机接口305，仍然必须回到控制室才能以控制端装置302-1到302-2加以控制。如此则造成维修及特别操作环境需求上有待改进的课题。However, the above structures cannot fully meet various changing environmental conditions or special operation needs. The reason is that the USB devices 301-1 to 301-4 connected to the USBhub port interface 301 only have the hub port function, but do not have the console function (such as giving instructions to eachcomputer interface 305, using hotkeys to each computer)interface 305, etc.). This is particularly difficult when the computer switch 300 and the console devices 302 - 1 to 302 - 2 connected to theconsole interface 302 are located in different places. For example, when thecomputer switcher 300 is installed in the computer room, and the console devices 302-1 to 302-2 connected to theconsole ports 302 are installed in the control room through wiring, the user cannot use the near-end The USB device 301-1 to 301-4 controls eachunconnected computer interface 305, and still must return to the control room to be controlled by the control terminal device 302-1 to 302-2. This results in issues to be improved on maintenance and special operating environment requirements.
