Follow-up tracking WIFI transmission device and control method thereof

Abstract

The invention discloses a follow-up tracking WIFI transmission device and a control method thereof. The device includes a cloud deck controller, and an acceleration sensor, a geomagnetic sensor, a Beidou navigation receiver, a wireless communication unit, a WIFI unit and an antenna cloud deck connected to the cloud deck controller. The device also includes a directional antenna arranged on the antenna cloud deck. The directional antenna is connected to the WIFI unit. The control method includes determining the coordinates of the device itself through Beidou satellite signals and sending the coordinate information to other access points; determining an optimal communication chain according to the combination of a routing algorithm and the coordinate information of the whole communication access point combined; determining the posture information of the device itself through the geomagnetic sensor; calculating the antenna azimuth angle and controlling the antenna cloud deck for antenna alignment. According to the invention, long range WIFI communication is realized and a problem of dynamic moving network construction of multiple access points when using the directional antenna is solved. Effects in aspects of prolonging WIFI communication distance, improving communication security, improving network invulnerability, reducing electromagnetic interference and the like are obvious.

Description

technical field [0001] The invention relates to the technical field of WIFI communication, in particular to a follow-up tracking WIFI transmission device and a control method thereof. Background technique [0002] WIFI communication is a very popular wireless communication method in contemporary society. WIFI communication has many advantages, such as large user capacity, high transmission speed, convenient access, wide use, and flexible networking. Modern smart terminals, such as mobile phones and mobile notebooks, usually use WIFI communication function as one of the standard configurations. [0003] Civilian unmanned aerial vehicles, especially multi-axis rotorcraft, have the characteristics of low cost, easy development, simple structure, and wide range of uses, and have been quite popular. But at present, most unmanned aerial vehicles are mainly controlled by a special remote control, and the drones that use WIFI communication can generally only communicate within 100...

AI Technical Summary

Problems solved by technology

However, directional antennas are directional and require the real-time alignment of the transceiver system to establish communication. Due to the high complexity of the directional communication system networking, it is currently limited to communication between point-to-point fixed locations, such as using directional antennas between two tall buildings. Bridge to realize WIFI communication, etc.

However, these conventional designs either increase the transmission power, or increase the antenna directivity and gain to improve the communication distance, and do not seek a solution on the WIFI signal itself

Moreover, these designs cannot meet the actual needs of mobile, random, and multi-access point networking.
