Problems solved by technology
[0004] The problem with the frequency hopping technology in the conventional technology is that when many peripheral devices use radio frequency to communicate wirelessly with the computer host at the same time or when a plurality of peripheral devices perform wireless communication with the corresponding computer host among the plurality of computer hosts, the frequency hopping has a negative impact on the communication. The characteristics of dynamic frequency changes may cause mutual interference between different peripheral devices, which will affect the quality of communication and even cause communication failure

Embodiment Construction
[0036] The embodiment of the present invention will be described in more detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it after studying this specification.
[0037] like figure 1 As shown, the computer radio frequency communication method described in the present invention is used to establish communication between the computer host 10 and at least one peripheral device 20, such as the wireless computer optical mouse in the figure, wherein the computer host 10 can use external radio frequency The transmitting and receiving module 15 is used to realize the communication with the peripheral device 20 , or the radio frequency transmitting and receiving module 15 is built in the computer host 10 , and this example is illustrated with the external radio frequency transmitting and receiving module 15 .
[0038] To be careful of, figure 1 Only a single peripheral device 20 is shown to communicate with the computer mainfra...

The invention discloses a wireless radio frequency communication method of a computer, comprising the following steps of: splitting a wireless radio frequency band into a plurality of transmission frequency channels; setting a target transmission frequency channel through software inside a computer mainframe, generating setting information, transmitting the setting information by the computer mainframe through an initial transmission frequency channel, receiving the setting information of the computer mainframe by a peripheral device through the initial transmission frequency channel, and communicating the peripheral device with the computer mainframe by using the target transmission frequency channel. The invention achieves the communication between the computer mainframe and the peripheral device and prevents the communication from being disturbed by the wireless communication of other computer mainframes and peripheral devices or wireless electronic devices by arranging the transmission frequency channels with specific frequency, thereby enhancing the quality and the stability of communication.
Description
technical field [0001] The invention relates to a computer radio frequency communication method, in particular to a method for selecting a specific frequency for communication between a computer host and peripheral devices. Background technique [0002] The communication method between the host computer and peripheral devices is generally wired, that is, electrical signals are transmitted by physical wires, such as serial ports (COM Port) or PS / 2 ports connected to a mouse or keyboard, and (Parallel ports) connected to a printer or modem. Port, PP), video graphics array (Video Graphics Array, VGA) interface or digital visual interface (Digital Visual Interface, DVI) connected to the display, universal serial bus (USB) connected to general peripherals, etc. Therefore, the host computer needs a lot of connecting wires to communicate with peripheral devices, but the connections not only take up too much space, but also are not easy to place, which often makes the surroundings o...
