Research And Design Of 5G Communication System Networking Technology For Industrial Workshop

With the rapid development of the modern communication,people pay more attention to the application of communication system technology in different fields.Especially in the modern industrial field,the communication system with high data rate,low transmission delay and high coverage probability enables the intelligence and digitalization of industries.However,in the existing industrial manufacturing workshop scenario,the network bandwidth,the transmission delay and data fusion calculation can no longer meet the requirement of simultaneous access for large-scale edge devices,which urgently calls for the improvement of current industrial network.Two important investigations can be carried out:the networking strategy and the performance optimization.Based on these,in this paper,we first design the networking method and access principle for industrial indoor scenario.Then,two system performance,including coverage probability and achievable rate are evaluated.Finally,a model for data calculation and offloading is proposed.The specific contributions are listed as follows:Firstly,for the problem of wireless signal propagation coverage calculation in industrial workshops(indoors),a process of wireless signal propagation model correction is proposed.In this process,the actual measured data is fitted by the least square method,and a wireless signal correction propagation model that can express the current industrial workshop(indoor)digital room subsystem is given.A new link budget model is studied and presented to calculate the coverage capability of a single small cell deployment in an industrial workshop.Secondly,for the problem of multi-terminal user access performance analysis,an industrial workshop(indoor)5G distributed base station model is established and studied,and the theoretical expressions of system coverage and transmission capacity in the downlink communication process are deduced.The verification simulation and data analysis were carried out.In addition,based on the data simulation analysis of different base station deployment schemes,the key parameters such as the coverage rate and transmission capacity of the downlink communication system based on the number of access users in the industrial workshop are calculated,and a suggestion for an optimal design scheme is given.Thirdly,in view of the problem of network performance analysis of the overall system data computing and offloading,a modeling method based on the data computing and offloading scenarios of equipment in the industrial workshop is proposed.Combined with the delay and the computing resources of the MEC(Multi-Access Edge Computing)server,a comprehensive cost-utility function is defined to analyze the network performance.At the same time,the variation trend of delay with the amount of MEC computing resources and the allocation of MEC computing resources under different access equipment terminals are studied and analyzed.Finally,a MEC communication system networking deployment scheme for industrial workshops is proposed for reference in actual construction and use on the basis of the research.
