A zigbee-based communication method between multi-quadcopters

Abstract

The embodiment of the invention discloses a ZigBee-based communication method among multiple quadrotor aircraft, and relates to the technical field of communication of multiple small aircraft. The invention includes: the sending end determines the transmission information according to the data type and the receiving end type, generates a combined data frame with the transmission information and transmission data, and the ZigBee communication module at the sending end converts the combined data frame according to the transmission mode selected by the transmission information in the combined data frame It is only sent to the receiving end pointed to by the transmission information in the combined data frame. After the ZigBee communication module of the receiving end receives the combined data frame, it obtains the transmitted data in the combined data frame and identifies the transmitted data by the address of the sending end in the combined data frame. end. It realizes point-to-point and point-to-multipoint communication between multiple quadrotors, quadrotors and the ground, and at the same time simplifies the data flow at the receiving end and ensures that the receiving end is full of required data, avoiding the communication channel occupied by receiving unnecessary data The situation improves the communication efficiency and avoids the data conflict among multiple machines.

Description

technical field [0001] The invention relates to the technical field of communication of multiple small aircrafts, in particular to a communication method between multiple quadrotor aircrafts based on ZigBee. Background technique [0002] In recent years, small quadrotors have attracted attention from all walks of life due to their unique advantages, such as easy manipulation, easy portability, and can be used in various complex environments to replace manpower and reduce costs. However, it is precisely because of its small size that its working capacity is limited, and its working range is greatly restricted. Many communication solutions and communication modules on medium and large aircraft are difficult to effectively apply to quadrotor aircraft, and more efficient ones need to be developed. Multiple quadrotors fly in formation to improve the working efficiency of the aircraft. Therefore, the multi-quadrotor communication method and cooperative formation method have becom...

Problems solved by technology

[0003] As far as the current technology is concerned, there have been some research results on the communication between multiple quadrotors. Although these research results can realize the communication between multiple quadrotors and between the quadrotors and the ground station, the communication efficiency is not high and the communication module receives Problems such as the congestion of data flow at the end and the inability to realize separate information exchange between any two quadrotors

For example: All quadrotors in the existing research use the broadcast mode of the communication module, which will cause the data stream at the receiving end of the communication module of the quadrotor to be crowded and the communication channel will be occupied due to receiving unnecessary data; or in multiple quadrotors The method of broadcasting data in turn will lead to many problems such as insufficient real-time data
