Design And Implementation Of A Large-scale UAV Measurement And Control Network Protocol

After the UAV is equipped with the measurement and control network system,the combination of the two can make it widely used in the military and civilian fields.In the military field,drones can be used to complete dangerous work behind enemy lines to collect intelligence;in the field of disaster relief,drones can be controlled to complete rescue work in complex environments;in the field of daily patrols,drones can be used to complete patrol work instead of police to reduce the burden on police officers.These rich applications make large-scale measurement and control networks have extremely important research significance.In actual scenarios,the wireless networking between the UAV and the ground control station has many problems and many challenges.These questions include insufficient number of UAV nodes supported by the network,unreasonable resource allocation due to limited wireless communication channel resources,unreasonable design of service transmission types,and insufficient utilization of hardware platform resources.In order to solve these problems,this paper completes the design and implementation of a largescale measurement and control network protocol.Finally,through the test on the hardware platform,it is found that the functions and performance indicators are basically satisfied.For large-scale measurement and control network protocols,this paper mainly completes the following work:（1）This paper analyzes the relevant background and technical status of the UAVmounted measurement and control network system.The background and research significance of the measurement and control network system are investigated,and then the current state of the related technologies of large-scale measurement and control networks is reviewed,including various network protocols,different resource scheduling algorithms and different technologies implemented.These provide a realistic basis and guide the direction for the following network protocol design.（2）This paper completes the demand analysis of the network system and the design of the large-scale measurement and control network protocol.Considering the practical application scenarios,the function of the large-scale measurement and control network protocol is described,and then the performance requirements and data indicators are proposed;according to the functional requirements and performance requirements,a large-scale measurement and control network protocol is designed,and the architecture design,Interface design,wireless resource allocation,and process design of different services;in order to improve the utilization of hardware platform resources and the efficiency of software operation,it is decided to adopt the network protocol implementation method of AMP architecture.（3）This paper describes the software implementation method and hardware platform implementation of the large-scale measurement and control network protocol,and then completes various testing tasks.Through the modular design idea,the key modules in the network protocol software are expounded;then the hardware operating environment is built,and the platform-related work is completed;finally,the tests of various functions and related performance indicators are completed,and it is found that the design basically meets the design requirements.requirement indicators.The large-scale measurement and control network protocol design and implementation completed in this paper can meet most measurement and control scenarios.It has high engineering significance and reference value in practical application.
