Problems solved by technology

Although 27MHz has the advantages of mature technology, low cost and low risk of interference, this type of keyboard and mouse products only support one-way transmission, that is to say, only the transmitter of the mouse can send signals to the signal receiver without "retrograde"
[0005] Today, NFC technology has matured and has been used in some practical applications in the field of mobile phones, but its application in wireless input devices for servers is seldom
For example, in a computer room with multiple servers, when the staff needs to use a set of input devices (wireless keyboard and mouse) to perform input operations on multiple servers, the current wireless input device needs to communicate with different servers Switching, either needs to be constantly reset to establish a connection, or needs to constantly plug and unplug the receiver on the server side (currently the keyboard and mouse using 2.4G wireless technology use this method), the work is more cumbersome, not suitable for large-scale applications, greatly Reduced efficiency of wireless device input control to target servers

Embodiment 1

[0034] like figure 1 shown.

[0035] A server wireless input device using NFC pairing, including a sending end and a receiving end, the sending end includes an NFC sending module and a 2.4G sending module, and the receiving end includes an NFC receiving module, a 2.4G wireless receiving module, and an MCU control module and USB interface. When using the device of the present invention, the sending end is installed in the wireless input device in the early stage, and the receiving end is respectively installed in a plurality of servers.

Embodiment 2

[0037] like figure 2 shown.

[0038] As described in Embodiment 1, the working method of the server wireless input device using NFC pairing includes the following steps:

[0039] (1) Power on the NFC sending module in the wireless input device and the NFC receiving module in the server respectively. Initially, the pairing identification ID maintained by the sending end is 0, and the pairing identification ID maintained by all receiving ends is 1. The NFC receiving modules of all receiving ends in a server start to monitor, and the 2.4G wireless receiving modules are in the closed state; as described in step (1), initially, because all the 2.4G wireless receiving modules are in the closed state, the wireless input device and All servers cannot communicate normally; when there is an NFC pairing connection, the MCU control module controls to turn on the 2.4G wireless receiving module, and the wireless input device and the server it is paired with have the same pairing ID, so th...

Abstract

The invention provides a server wireless input device adopting near field communication (NFC) matching. A core of the server wireless input device adopts an NFC technology and a wireless communication technology. A transmitting end and a receiving end are respectively installed on a wireless input device and a target server, wherein the transmitting end comprises an NFC transmitting module and a wireless communication transmission module, and the receiving end comprises an NFC receiving module, a wireless communication receiving module, a microprogrammed control unit (MCU) control module and a universal serial bus (USB) interface. The invention further provides a working method of the server wireless input device adopting the NFC matching and aims at achieving application of a keyboard and a mouse of one set of wireless input devices communicated with multiple servers and enabling the keyboard and the mouse exclusively correspond to the target server in the multiple servers through the NFC technology and close-range contact and matching and then perform exclusive input operation. In addition, the switching selection of the wireless input devices among the multiple servers is further achieved by utilizing the NFC technology and the close-range contact.

Description

technical field [0001] The invention relates to a wireless input device for a server using NFC pairing and a working method thereof, belonging to the technical field of wireless communication between a computer input device and a server. Background technique [0002] NFC is the abbreviation of NearField Communication, short-range wireless communication, commonly known as near-field communication. It was jointly developed by Philips and Sony. NFC is a non-contact identification and interconnection technology that enables short-range wireless communication between mobile devices, consumer electronics, PCs and smart control tools. It is an extremely short-range radio frequency identification communication protocol technical standard. Technically, it adopts identification technology similar to RFID and combines wireless network protocol to transmit data. [0003] Like RFID, NFC information is also transmitted through electromagnetic induction coupling in the radio frequency p...
