Problems solved by technology

If the retransmission mechanism is removed, it is indeed possible to update the data every 1ms and achieve a data return rate of 1000Hz, but as long as there is interference, it is impossible to stabilize at this value. In fact, if the retransmission mechanism is not used, the return rate will fluctuate greatly , which is equivalent to the fast and slow response speed of the mouse, which is actually worse than 125Hz, which seriously affects the user experience
Therefore, the current 2.4G wireless mouse solution cannot meet the requirements of gaming mice, and almost all e-sports gaming mice still use wired USB.

[0043] figure 1 A structural block diagram according to the first embodiment of the present invention is shown. Such as figure 1 As shown, a wireless transmission system has a wireless data sending device S101 and a wireless data receiving device S102. In one embodiment, the wireless data sending device S101 is a wireless mouse device. The wireless data receiving device S102 is a USB wireless adapter (hereinafter referred to as adapter) corresponding to the mouse. Each device contains a 2.4G radio frequency wireless transceiver module (hereinafter referred to as RF module) S103, the communication rate of this wireless transceiver module is 1Mbps, adopts GFSK modulation method, and has two modes: RX (receiving) and TX (transmitting). Transition time between TX and RX mode <150us. The size of the data packet of the wireless transceiver module is variable, and the size of the data packet can be set through a corresponding register. For example, when used for mouse data trans...

[0050] Figure 4 A structural block diagram according to the second embodiment of the present invention is shown. Such as Figure 4 As shown, a wireless transmission system has a wireless data sending device S401 and a wireless data receiving device S102. In one embodiment, the wireless data sending device S401 is a wireless mouse device. The wireless data receiving device S102 is a USB wireless adapter corresponding to the mouse. The wireless mouse device uses a main control MCU chip S402 that supports both Bluetooth 5.0 and 2.4G private protocol dual modes. The chip contains a Bluetooth 5.0-compliant RF module S403 and a Bluetooth baseband module S404. The Bluetooth baseband module S404 is used to control the data packet format of the RF module S403. In one embodiment, the register can be used to set the data packet format to be a Bluetooth 5.0 data packet or a 2.4G private protocol data packet. Since the definition of the RF radio frequency module in the Bluetooth 5.0...

Abstract

The present invention provides a wireless data transmission control method, comprising: providing a sequence of frequency points; the data sending end and the receiving end perform several times of communication after synchronization, record the frequency points with good signal quality and generate a list of frequency points; The unit performs data transmission, divides the time interval into at least two time periods, each time period corresponds to a channel, selects at least one channel as the main channel, and at least one channel as the secondary channel. During each data transmission, all channels complete a communication , and keep the main channel communicating at a certain frequency point, and the secondary channel switches to a different frequency point for each communication, so as to detect the frequency point with good signal quality and update the frequency point list; for example, at the xth data transmission If the main channel communication fails, switch the secondary channel to the most effective frequency point in the frequency point list for communication; then set the frequency point of the main channel as the secondary channel for the x+1th and subsequent data transmissions The frequency point used at the time, the secondary channel will continue to detect and update the frequency point list.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a 2.4G wireless data transmission control method. Background technique [0002] Mouse has been used as a peripheral device of personal computer for more than 30 years, and its status as a human-machine input device is still unshakable until today. The main control MCU of an ordinary wired mouse uses the USB 1.1 communication protocol. The USB works in low-speed mode, and the data transmission interval is 8ms, that is, one data packet is sent and received every 8ms, and the data return rate is 125Hz, which is enough for basic computer operations and Office needs. However, with the rise of computer games and the vigorous development of competitive games, the 125Hz response speed of ordinary mice is not enough, which seriously affects the game experience, so a mouse specially used for games has been derived. Gaming mice are basically wired mice. The main control MCU...
