Design And Implementation Of Dtv Front-end Equipment Management Platform Based On Android Dynamic Loading Technology

With the popularization and development of digital TV technology,the system of digital TV front-end equipment becomes more and more complex.The unified management of digital TV front-end equipment has become an important task in the fields of radio and television.At present,in the fields of radio and television,the management of administrators is mostly restricted to PC,and the flexibility is limited.Realizing the management of digital TV front-end equipment on the mobile end has become a new demand and research direction in the fields of radio and television.Based on the research of digital TV and its front-end equipment management status,combined with the new requirements,this topic designed and implemented digital TV front-end equipment management platform which was based on Android dynamic loading technology.Firstly,this paper introduces the key technologies involved in the research,analyzes the difficulties in the realization of the dynamic loading technology of Android platform,and gives the solution of this topic.Solving the access problem of resources by the reflection mechanism and solving life cycle management problems of Activity by the interface callback mechanism.Then,this paper introduces the specific design and implementation of the equipment management platform.The management platform is divided into the client and the server side.The client needs to manage a variety of different types of devices in a unified way.In order to avoid the large complexity and frequently updates of the system,this topic adopts the plug-in design.The whole system is divided into the outer unified management platform and inner layer specific device management plug-in.The outer management platform invokes device plug-in through dynamic loading technology,and the plug-in realizes device management based on SNMP protocol.The implemented functions include:subnet customization,device parameter acquisition and configuration,device off-line monitoring,device alarm information receiving,user login registration,system update and other basic functions of APP.The server side is built based on the LAMP architecture,providing support for the normal operation of client APP.Finally,this paper introduces the system testing situation.The management platform has passed the functional test,performance test and compatibility test.From the test results,we can see that the entire management platform function meets the needs,the performance is stable and reliable,and the compatibility is good.
