Research On Structural Design And Transmission Optimization On Equipment Support Internet Of Things

Modern warfare is characterized by sudden emergence,multitudinous elements,large battlefield consumption,and rapid rhythm change.Weapons and equipment have played an increasingly prominent role in the victory of war,and it has become increasingly difficult to implement equipment support.At present,our military has a low level of informatization in organizing equipment support.It is unable to grasp the weapons and equipment performance in real time,the allocation of equipment support force,the distribution of maintenance equipment,and the progress of repair tasks.It is difficult to implement precise and efficient command and dispatch.Therefore,this topic applies the technology system of the Internet of Things to the equipment support business,researches the hardware deployment,architecture,transmission network,and functional modules of the equipment support Internet of Things,and proposes a preliminary implementation plan theoretically and technically,in order to speed up the practical application of the Internet of Things in battlefield equipment support.This topic mainly provides research on four aspects.The first is to summarize the status quo of research on IoT research and equipment support IoT,and to analyze the practical needs and significance of IoT in battlefield equipment support.The second is to design the system architecture of equipment support IoT.The general principle of network design is proposed and the network is designed layer by layer.In perception layer,the technical selection and construction programs of RFID systems,sensors,and military wireless sensor networks are proposed.In network layer the,the connection scheme and topology structure of satellite communication networks,mobile communication networks,backbone fiber communication networks,and tactical radio networks,are proposed.In terminal application,according to the "central-area" distributed model,and the architecture of the software system is proposed based on the protection of the business relationship.The third is to use simulation technology to optimize system performance.In order to solve the power consumption problem of the wireless sensor network and the spectrum allocation of the wireless channel in the network layer,which are the most important factors affecting the performance of equipment support Internet of Things,optimization algorithms are proposed respectively.The performance of the algorithm is verified through simulation.Aiming at the power consumption problem of heterogeneous sensor networks,this paper proposes a data aggregation route algorithm,which aggregates the different data received by nodes,reduces the data transmission redundancy,and prolongs the network lifetime.Aiming at the problem of spectrum allocation in radio networks,a joint optimization algorithm for radio association and spectrum allocation(JORS)is proposed.The optimal spectrum allocation solution is obtained by using the method of operations research,in which both radios' load intensities and SNRs into account are considered comprehensively.The fourth is to research and develop the equipment support and command system based on the equipment support internet of things.According to the equipment support business content,work flow,user objects,and the division of functions,based on the equipment support internet of things,this project developed the equipment support command system.This topic elaborats the system database construction ideas specifically,design the data structure,according to the logical relationship and the physical distribution.The overall architecture of the software system was introduced,specific functions,process and implementation method of six equipment support business function modules,such as equipment condition monitoring,equipment performance evaluation,equipment fault diagnosis,equipment maintenance decision-making,equipment supply,and equipment support force command,ere specifically described.
