Abstract

The present invention changes the existing USB device connected to the USB terminal through the application device consisting of the switch control unit, switch, memory, wired / wireless devices 2, plug, etc., the call command from the host of PC 1 The switch control unit operates according to the detection of the wireless device 2 or the detection of data movement in the wired / wireless device 2 so that the path of the memory is automatically changed to enable bidirectional wired / wireless communication between the PC and the PC and various communication devices. It is an invention to make it.

Description

Realization of data communication between PC and PC in auto-switching of memory path with Switch Control circuit}

The present invention relates to a method for enabling data communication between PCs by changing an existing USB device. The path of a memory is automatically changed by a switch control unit that detects a call command and data movement from a PC. It is an invention that enables a bi-directional wired / wireless communication between a PC and a PC by configuring a device to allow the communication.

In the existing PC, the communication using the USB terminal is a PC, and the rest becomes a device, and only wired / wireless communication between the host and the device is possible, and data communication between the PC and the PC is impossible.

The present invention proposes a solution to the above problems, the device using a conventional USB terminal By operating the switch control unit, it aims to make the communication between PC and PC which was impossible in the communication using the existing USB terminal automatically.

As shown in the attached drawing 1, a wired / wireless device 1 is connected to the USB Receptacle1 terminal of PC1, and an application functioning as a device composed of memory, wired / wireless device 2, switch control unit, switch, and plug to the USB Receptacle2 terminal of PC2. The device is connected.

Herein, the wired / wireless device 1 connected to the USB Receptacle1 terminal of the PC1 and the wired / wireless device 2 in the application device of the PC2 refer to wired and wireless devices that provide a means for mutual linking.

In addition, the memory constituting the application device of the PC2 refers to flash memory, SD card, HDD.

Switch control unit connects ②① of Figure 1 to connect the memory and wired / wireless device 2 when the switch use signal is received from PC1 for the first time or data movement of memory is continuously detected in wired / wireless device 2. If data movement is not detected in wired / wireless device 2, connect ①③ in Figure 1 so that memory is connected to USB terminal D +, D- of PC2.

 Due to the present invention having the above structure, the path selection of the memory is automatically performed through the control of the switch control unit, so that the user can use the data communication between the PCs without inconvenience.

Hereinafter, with reference to the accompanying Figure 1 will be described an embodiment of the present invention.

As shown in the accompanying drawings, in the first embodiment of the present invention, in the case where it is necessary to use or operate the contents of the memory connected to the PC2 in the PC1, the PC1 is the main and the PC1 is connected to the PC2 through the wired / wireless device 1. When calling wired / wireless device 2 or if data flow is continuously detected from wired / wireless device 2, the switch control unit of wired / wireless device 2 is operated so that the connection status of the switch is continuously connected to memory and wired / wireless device 2. By automatically connecting ② and ① shown in Figure 1, you can use or operate the contents of the memory in PC1, and also enable the operation of inputting new data into the memory in PC1.

The second embodiment is a case in which the contents of the memory are used or operated in the PC2. In this case, the wired / wireless device 2 checks the data movement to the memory in time and if the movement of the data is not detected, the link to the wired / wireless device 1 is off. It will notify you and enter link off mode.

At this time, the switch control part of the wired / wireless device 2 automatically operates to automatically connect ① and ③ shown in Figure 1 to connect the memory to the USB terminals D + and D- of the PC2. It also allows you to enter new data into memory from PC2.

1 illustrates a conceptual configuration of the present invention.

Figure 2 illustrates an application to the application of the present invention.
