Embodiment 1

[0091] Such as figure 1 As shown, a frame time slot Aloha access method for unmanned swarm network monitoring and control includes the following steps:

[0092] S1. The terminal of the unmanned swarm network measurement and control system starts up, receives the default frequency point signal, and designs the timer t 1 Then judge the status of the terminal to broadcast, and send a frame slot Aloha network access application to the cluster head node;

[0093] Terminals include airborne nodes A(m) and ground nodes. The number of airborne nodes A(m) is M, and the number of ground nodes is 1. Airborne nodes include cluster-head nodes, sub-cluster-head nodes and ordinary airborne nodes. node;

[0094] System frame T of unmanned swarm network measurement and control system s Including N time slot frames, N≥M+2, each time slot frame includes 1 time slot pair, frame time slot Aloha network access application is set in system frame T s Among them, the time slot pair includes the ai...

Embodiment 2

[0125] Such as figure 1 As shown, a frame time slot Aloha access method for unmanned swarm network measurement and control, figure 2 It is the system scene diagram, the vehicle-mounted ground station is connected to the ad hoc network system as a full peer node, the drone can contain different models, and there are cluster heads, sub-cluster heads, and new nodes in the networking cluster. These networking nodes dynamically allocate frame time slots 1, 2, 3...random access time slots in the system frame.

[0126] image 3 Shown is the processing flow chart of the Aloha access method of the frame time slot. After the terminal A(·) is turned on, it receives the signal of the default frequency point and judges that it is at t 1 If there is no information, A( ) itself will be the quasi-cluster head and prepare to broadcast; if there is information, it will analyze the cluster head and connection status information, continue to receive when there is no cluster head, and apply for...

Abstract

The invention provides a frame time slot Aloha access method for unmanned cluster networking measurement and control, which comprises the following steps of: starting a terminal of an unmanned cluster networking measurement and control system, receiving a default frequency point signal, setting a timer t1, judging the state of the terminal, broadcasting, and sending a frame time slot Aloha network access application to a cluster head node; after receiving the frame time slot Aloha network access application, the cluster head node performs legal authentication on the terminal and allocates a basic frame time slot; and when the terminal actively and passively withdraws the network, the unmanned cluster networking measurement and control system performs dynamic management. According to the method, on the basis of adopting SC-FDE physical layer signals, frame elements of a link layer are designed, time slots of airborne nodes and ground nodes are unified, the time slot Aloha network access application method based on the cluster head node link state is obtained, and the method has the advantages of being low in network delay and the like.

Description

technical field [0001] The invention relates to the technical field of telecommunication technology, in particular to a frame time slot Aloha access method for unmanned swarm network monitoring and control. Background technique [0002] In the UAV cluster network collaborative task system, the ground network node can participate in the full peer-to-peer non-central network communication as an ordinary node. At this time, the airborne networking node transmits inter-machine information to other airborne networking nodes, and transmits telemetry information to the ground networking node. The ground networking node has no flight control coordination requirements, and needs to transmit remote control information to the airborne node. This kind of simultaneous measurement and control and inter-machine communication for multiple UAVs requires the cluster head node to connect to multiple nodes, and it is necessary to design an efficient network construction and network access proto...
