參照圖2，其為根據本發明之具有無線介面模組之電腦切換器之另一實施例的結構方塊圖。在本實施例中的基本結構與圖1所示之基本結構相同，不同之處在於中間機構為主控制微處理器105及切換電路108。主控制微處理器105藉由程式化該切換電路108而選擇欲操控的電腦介面106及其所連結的電腦主機107，以進行接續的訊號傳輸。對於無線輸入訊號的傳輸而言，無線 輸入訊號封包分成資料封包與命令封包。資料封包為包含資料的封包，命令封包為包含切換電路108應切換到哪一個電腦介面106的命令的封包。主控制微處理器105可辨識無線輸入訊號封包為何種封包。初始時切換電路108未與任何電腦介面106相連，當主控制微處理器105初始收到訊號封包，將辨識出封包為命令封包，此時該主控制微處理器105使切換電路108切換到命令封包所指定的電腦介面106，以形成封包通路，而後解除對該資料傳輸之控制。而後續的資料封包分別經由無線介面模組103、輸出/輸入裝置介面104、切換電路108、電腦介面106、電腦主機107的路徑而傳送到電腦主機107。但主控制微處理器105不須對資料封包作任何處理，而由該切換電路108直接與電腦介面106作資料傳輸。另一方面，電腦主機107所欲傳送的電氣訊號經由切換電路108直接送回輸出/輸入裝置介面104(而不經過主控制微處理器105)，再傳送到無線介面模組103以轉換為無線輸出訊號105。此種結構的優點在於減少主控制微處理器105的處理工作，使主控制微處理器105的資源可用以進行其他運算或是滿足其他要求。其他與圖1所示之實施例相同的結構及功能不再贅述。 2 is a block diagram showing another embodiment of a computer switcher having a wireless interface module in accordance with the present invention. The basic structure in this embodiment is the same as the basic structure shown in FIG. 1, except that the intermediate mechanism is the main control microprocessor 105 and the switching circuit 108. The main control microprocessor 105 selects the computer interface 106 to be controlled and the computer host 107 to which it is connected by programming the switching circuit 108 for subsequent signal transmission. For the transmission of wireless input signals, wireless The input signal packet is divided into a data packet and a command packet. The data packet is a packet containing the data, and the command packet is a packet containing a command to which computer interface 106 the switching circuit 108 should switch to. The main control microprocessor 105 can identify which packet the wireless input signal packet is. Initially, the switching circuit 108 is not connected to any computer interface 106. When the main control microprocessor 105 initially receives the signal packet, it will recognize that the packet is a command packet, at which time the main control microprocessor 105 causes the switching circuit 108 to switch to the command. The computer interface 106 designated by the packet is formed to form a packet path, and then the control of the data transmission is released. The subsequent data packets are transmitted to the host computer 107 via the paths of the wireless interface module 103, the output/input device interface 104, the switching circuit 108, the computer interface 106, and the computer host 107. However, the main control microprocessor 105 does not need to perform any processing on the data packet, and the switching circuit 108 directly transmits data to the computer interface 106. On the other hand, the electrical signal to be transmitted by the host computer 107 is directly sent back to the output/input device interface 104 via the switching circuit 108 (without passing through the main control microprocessor 105), and then transmitted to the wireless interface module 103 for conversion to wireless. Output signal 105. The advantage of this configuration is that the processing of the main control microprocessor 105 is reduced, allowing the resources of the main control microprocessor 105 to be used for other operations or other requirements. Other structures and functions that are the same as those of the embodiment shown in FIG. 1 will not be described again.

Computer switcher for line interface module. The wireless interface module 303 is a standard wireless interface module that can output/input various standard specifications of wireless output/input signals. The wireless interface module 303 is connected to the output/input device interface 3042 of the standard computer switch 301 via an output/input device interface 3041, such as USB or PS/2. In this embodiment, the transmission path of the wireless output/input signal is similar to the embodiment shown in FIG. 2 (ie, the main control microprocessor 105, the computer interface 106, the computer host 107, and the switching circuit 108 are equivalent to the main The microprocessor 305, the computer interface 306, the computer host 307, and the switching circuit 308 are controlled, except that the signals are via two output/input device interfaces (3041, 3042). Other signal transmission paths and methods similar to those in FIG. 2 are not described again.
