Description

计算机转换开关以及其方法 Computer switch and a method thereof

技术领域 FIELD

本发明涉及一种切换装置,且特别涉及一种可供多台串接且兼容性佳的计算机转换开关以及其方法。 The present invention relates to a switching device, and more particularly to a plurality of series and for good compatibility with computer switch and a method thereof.

背景技术 Background technique

由于信息技术的快速发展,使得计算机及其外围产品的应用相当普及。 Due to the rapid development of information technology, making the application of computers and peripheral products quite popular. 计算机使用者通常利用鼠标及键盘等输入外设对计算机进行操作,计算机藉由监视器或喇叭等输出外设,将计算机状况显示在监视器或利用声音指示,使计算机使用者可以随时掌握计算机的实时状况。 Computer users usually use a mouse and keyboard input peripheral computer operates like a computer monitor or speakers by output peripherals, computer monitor or the status display instruction by voice, a user can control a computer causes the computer at any time Real-time status. 有时候为了满足不同的需求,使用者可能拥有不只一台的计算机来处理各类不同的事情。 Sometimes in order to meet different needs, users may have more than one computer to handle different kinds of things. 传统上,每台计算机都应配备一组操作装置,例如键盘、鼠标、监视器及喇叭等,但是这种配置方式却十分浪费金钱与空间。 Conventionally, each computer should be equipped with a set of operating means such as a keyboard, mouse, monitor and speakers, but this arrangement is very waste of money and space.

在另一方面,大型的系统业者或是中小型的企业内部网络,通常拥有多则上千台或至少数台的服务器,而每台服务器都需使用监视器,键盘及鼠标以作为管理所需。 On the other hand, large-scale system operators or small and medium enterprises internal network, usually have as many or at least several thousands of servers, and each server needs to use a monitor, keyboard and mouse as required management . 但实际上在使用服务器时,却极少需要使用到这些操作装置,在大部分的时候服务器是不需要被管理者所控制的。 When actually using the server, rarely need to use these operating means in the server is not required most of the time to be controlled by the manager. 因此,在这种情况下,每台服务器使用个别之一组操作装置是不必要而且也不合成本的,而且还会造成空间的浪费。 Thus, in this case, each individual server using one set of operating means is not necessary and does not present the synthesis, but also wasteful of space.

于是一种计算机转换开关(Keyboard-Video-Mouse Switch;KVMSwitch),使用至少一组操作装置来管理多台计算机的装置,解决了这样的问题。 Thus a computer switch (Keyboard-Video-Mouse Switch; KVMSwitch), using at least one set operating device management apparatus multiple computers to solve such a problem. 使用计算机转换开关不仅仅解决费用的问题,还解决了设备及空间的问题,同时也可克服不同接口的兼容性问题。 Using a computer switch not only solve the problem of cost, but also solve the problem of equipment and space, but also to overcome the compatibility issues of different interfaces.

然而,单一计算机转换开关由于本身的硬件设计与成本限制,其可容纳连接的操作装置的组数以及计算机的个数有限。 However, a single switch since computer hardware design and cost constraints itself a finite number of operating means which can accommodate the number of groups and connected to the computer. 另一方面,熟知的计算机转换开关彼此间并不容易进行串接。 On the other hand, well-known computer switch connected in series with each other is not easy. 而且,当多组操作装置同时使用多台计算机时,各操作装置与各计算机间的连接协议并不一定相同,常用的连接协议例如有通用串行总线(Universal Serial Bus;USB)接口、串行端口(COM)接口或个人计算机第二代系统(Personal System/2;PS/2)接口等。 Further, when the plurality of sets of operation device simultaneously use multiple computers, connected to respective operating means and the protocol between computer are not necessarily the same, for example, commonly connected to a universal serial bus protocol (Universal Serial Bus; USB) interface, a serial port (COM) interface to a personal computer or a second generation system (personal system / 2; PS / 2) interface.

这些不同的连接协议会降低计算机转换开关的兼容性,并拖累多台串连时信号的交换效率。 These different connection protocols may reduce the compatibility of a computer switch, and dragged exchange efficiency plurality of signal series. 举例来说,当键盘的连接协议为通用串行总线接口,但计算机的连接协议为个人计算机第二代系统接口时,熟知的计算机转换开关通常会选在接收键盘的电子信号时或是选在发送至计算机时将其由符合通用串行总线接口转为符合个人计算机第二代系统。 For example, when the keyboard is connected to a universal serial bus interface protocol, but the connection protocol of the computer is a personal computer interface to a second generation system, well known in the switch is usually selected from the computer when receiving electronic signals at a keyboard or selected from when sent to the computer which was converted from the coincidence universal serial bus interface system in line with second-generation personal computer.

然而,这种熟知的处理方式对于多台串接的计算机转换开关而言并不适用。 However, this known approach for multiple computers switch connected in series in terms do not apply. 多台串接的计算机转换开关若要传递不同连接协议的电子信号,则其内部必须提供适用于各种不同连接协议的电路,这不但增加了设计的难度,不易提高其兼容性,而且也会严重降低其使用效率。 A plurality of serially connected switch computers connected to different transmission protocol of the electronic signal, it must provide an internal connection protocols suitable for various circuits, which not only increases the difficulty of design, easy to improve compatibility, but also severely reducing its efficiency.

上述缺点在使用者实际使用时会带来许多不便。 The above-mentioned disadvantages when the user actually used will bring a lot of inconvenience. 尤其对于大型的系统业者或是中小型的企业内部网络而言,计算机转换开关若无法同时使用为数庞大的操作装置以及计算机,不但会提高系统架设与维护的成本负担,且也会拖累整个网络的通讯效率。 Especially for large-scale system operators or small and medium enterprise network, the computer switch can not be used if a large number of operating devices and computer at the same time, will not only increase the cost burden on the system set up and maintenance, and also dragged down the entire network communication efficiency.

第一接口114还具有第一译码装置164,用以将电子信号转换成标准包,供送入切换装置120以进行路径安排。 First interface means 114 further includes a first decoder 164, for converting electrical signals into a standard package for feeding path switching means 120 for arrangements. 切换装置120,例如切换芯片、可程序化芯片或中央处理器,根据一路径选择设定,将标准包发送至其目的的第二接口112,供传递至其目的的本地端计算机152。 Switching means 120, for example, switching chip, a chip or a programmable central processor, according to a selected path is set, sends the packet to the standard interface 112 a second object, the local computer 152 for delivery to the end of its purpose.

多组第二接口112,例如通用串行总线(Universal Serial Bus;USB)接口、串行端口(COM)接口、个人计算机第二代系统(Personal System/2;PS/2)接口、红外线接口、蓝牙接口或其它有线及无线接口,连接多台本地端计算机152。 A second plurality of sets of interface 112, for example, a universal serial bus (Universal Serial Bus; USB) interface, a serial port (COM) interface, a second-generation personal computer system (Personal System / 2; PS / 2) port, an infrared interface, Bluetooth interface or other wired and wireless interfaces, connected to a plurality of local computers 152. 而且,第二接口112还具有一第二译码装置162,用以将标准包转换成符合其路径目的的本地端计算机152的连接协议的电子信号,供送入其目的的本地端计算机152。 Further, a second interface 112 further includes a second decoding means 162, to convert it to conform to the standard packet of the path to the destination local computers connected to the electronic signal protocol 152, for the purpose of feeding the end of the local computer 152.
