Transmission method by radio virtual frequency channel

Abstract

This invention relates to wireless virtual channel transmission method used in digital transmission of wireless sub equipment and master equipment with many sets of different family ID and security ID, the sub as the transmitting party, the master as the receiving party. The transmitting party sends out any set of family ID and security ID by a press key or trigger device and the receiving party receives and identifies it to be set as the bases of digital transmission and identification. The same set family ID and security ID are entered the sub and master equipments in every wireless transmission information series as the base of digital transmission and reception to simulate one or many wireless digital transmission channels.

Description

field of invention [0001] The invention relates to a transmission method of a wireless virtual channel, in particular to a method for setting up a communication channel for wireless data transmission. Background of the invention [0002] Wireless transmission is a digital data transmission method commonly used by computers or electronic equipment, such as signal and data transmission between a wireless computer host and a wireless computer keyboard or a wireless mouse or a wireless joystick, data transmission between two wireless USB devices, and wireless control The control data and command transmission between the host computer and the controlled sub-machine must be achieved through two-way wireless transmission. However, the wireless transmission mode between the existing computers or electronic equipment is between the host computer and the sub-machine In the electronic circuit, the transmitting and receiving circuit with the same frequency is designed so that digital da...

[0002] Wireless transmission is a digital data transmission method commonly used by computers or electronic equipment, such as signal and data transmission between a wireless computer host and a wireless computer keyboard or a wireless mouse or a wireless joystick, data transmission between two wireless USB devices, and wireless control The control data and command transmission between the host computer and the controlled sub-machine must be achieved through two-way wireless transmission. However, the wireless transmission mode between the existing computers or electronic equipment is between the host computer and the sub-machine In the electronic circuit, the transmitting and receiving circuit with the same frequency is designed so that digital data can be transmitted between the two. For example, taking the computer host and the wireless keyboard as an example, there are electronic circuits with the same communication frequency or channel between them. , the transmission communication can be carried out quite smoothly during stand-alone communication, but when there are several computer hosts and wireless keyboards using the same frequency or channel communication for wireless transmission of digital data in the same area, mutual communication frequency interference will occur repeatedly. Errors in data transmission and reception

[0003] There may be improvements due to this, such as adding a switch or a jumper to switch between different communication channels in the electronic circuit of the existing computer host or wireless keyboard, and it is necessary to modify the circuit of the electronic circuit during manufacture The design and layout relatively increase the cost of the product, and when in use, the user must make the same setting and operation of the switching switch and the short-circuit clip code on the host computer and the wireless keyboard, and each user must coordinate and allocate channels by himself And memorizing the channel code assigned to oneself will only increase the inconvenience of the user's operation, and this existing communication channel operation mode of modifying the hardware circuit and switching the setting through the switch or short-circuit clip, in addition to the inconvenience of operation In addition to the shortcomings, the number of channels is easily limited. When the number of computer hosts and wireless keyboards increases too much, the original communication channels will be insufficient, and it is necessary to fully renew the wireless communication interfaces and wireless keyboards of all computer hosts. The cost of using the system as a whole
