Description
Technical Field
The invention relates to the technical field of 2.4g communication pairing, in particular to a remote controller and airplane short-distance code matching method.
Background
At present, the code checking mode is generally in a distance of remote code checking by dialing up and down a rocker, and although the code checking mode can be operated in a remote distance, a remote control can possibly occur to control a plurality of airplanes. There is also a one-to-one code pairing scheme, but also in the case of very high code pairing power, the remote control pair may not be the airplane that we want to be paired with.
Although the current code matching mode can be one-to-one code matching, if a plurality of airplanes exist around the airplane, the airplane may be matched with other airplanes, but not the airplane which we want to be matched with.
Therefore, the remote controller and the airplane short-distance code matching method are necessary to solve the problems.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, provides a remote controller and an airplane short-distance code matching method and solves the problems.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the remote controller and the airplane short-distance code matching method comprises the following code matching steps:
s1, setting the power to be in the range of X when the codes are matched;
s2, returning by using the function of 2.4G ACK return;
and S3, performing one-to-one code by using a three-way handshake protocol.
Preferably, wherein X is-18 db.
Preferably, the 2.4G ACK backhaul method comprises the steps of:
the airplane acquires whether the remote controller has data to send to the airplane, and if the data of the remote controller is confirmed to be sent to the airplane, the next step is carried out;
the remote controller carries the data by using a response signal sent by the remote controller to the airplane;
when the data volume required by the airplane is large, the airplane is communicated with the remote controller for multiple times to obtain enough data information.
When the airplane sends data to the remote controller, the remote controller is in a data receiving state, and after the data is received, the remote controller sends response information to the airplane.
When the state of the remote controller is idle, the slave does not react.
The three-way handshake protocol comprises the following steps:
first handshake: when establishing connection, the client sends a SYN packet to the server, and counts the SYN _ SENT state to wait for the server to confirm;
second-layer handshake: the server receives the SYN packet, must confirm the SYN of the customer end, one oneself also sends a SYN packet at the same time, namely SYN + ACK packet (receive message and respond), the server enters SYN _ SENT state at this moment;
third handshake: and the client receives the SYN + ACK packet of the server and sends an acknowledgement packet ACK to the server, and after the packet is sent, the client and the server enter an Established state. I.e. the TCP connection is successful, the three-way handshake is completed.
The invention has the beneficial effects that: the invention sets the power to a very low range when the codes are matched, ensures that the effective communication range is in a very small area, and realizes a one-to-one function by utilizing the function of 2.4G ACK return and the three-way handshake protocol, thereby enabling the remote controller to be more accurately matched with the target airplane.
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings to fully understand the objects, the features and the effects of the present invention.
