Design And Implementation Of Video-middle Station System Based On Operator Sharing

At present,5G technology is developing rapidly in China,and its new communication information carrier represented by video application is attracting the attention and use of a lot users.In order to promote the sharing of operator technology,the sharing of operator resources and the co-building of operator performance,this thesis designed and implemented a video-middle station system based on operator sharing.Through the creation and management of operators,the system tracks the operator call and application status in the application,and provides reliable and stable operator sharing services for users with various operators requirements,which can avoid the repeated research and development of the same type of operators,and reduce the development cost.This thesis first introduces the research background and significance of the system,analyzes the domestic and foreign research status of common operator classification and the videomiddle station system scheme.It also expounds the related theories such as the Django framework,Celery task scheduling tool,MTCNN algorithm for the realization of the system.Secondly,taking face detection operator as an example,the function model and dynamic model are used to analyze the requirements of the system business.After that,the system needs to realize the functions of operator creation,operator management,application management,approval management,user management and health inspection,and put forward the non-functional requirements of the system.Thirdly,in the system design,the system architecture design,functional structure design and database design are elaborated in detail.When designing the function of operator,the face detection algorithm of multi-task cascade convolutional neural network MTCNN is taken as an example to illustrate the functional structure design of the module,and using E-R diagram to complete the system database design.Fourthly,in the realization of the system module,the static structure of each module is described by the core class diagram,the dynamic collaboration among multiple objects is described by the sequence diagram,and the realization of important modules such as operator creation,operator management,application management and approval management is shown.Finally,the thesis completes the functional and non-functional tests of the system and analyzes the test results.The running results of the system show that the system has achieved the design objectives,achieved the operator sharing service,reduced the cost of software development,and has a broad application prospect.
