Design And Implementation Of Experiment Management System Based On The Mobile

Currently,the widely used experimental information management system in universities is a series of web-based systems,which mainly based on the B/S architecture model.This kind of system improves the management efficiency to a certain extent.However,this approach has a strong dependence on the PC,with poor movement,and limited by time and space.And such systems is not effective for real-time data interaction,timeliness of information release.In this context,this article combines Android development technology,designed and implemented a Mobile Terminal-based experiment management system with message push function,which is used as an assistant of web-side experimental management system for the management of experimental classroom.In the overall design of the system,it is necessary to consider the system scalability,concurrency,system responsiveness and immediate information interaction capabilities.For this reason,this thesis has conducted the following researches:For the system architecture,this thesis adopts a combination of B/S and C/S technology to carry out the overall system design.Considering scalability of the system,the idea of systematic layered design were introduced.Using the separation of front and back service,the system is divided into three layers: application layer(presentation layer),service bearing layer,and application support layer.For the concurrency of the system,in the design of Server,this thesis adopts the method of task processing and data storage separation to design the Server platform.Deploy Tomcat on the Application Server to preform task request processing.The Nginx Server and MySQL database were deployed on the Data Server to implement load balancing and database operations.And choose Memcached,a distributed memory cached system,to achieve Session sharing between Tomcats.In order to speed up the system response rate,this thesis adopts the thread pool mechanism based on First Come First service task scheduling to request processing task,and Batch storage is used for data storage.For the message push,based on the analysis of the existing message push solutionAndroid PN,this thesis improved and integrated it into the system.The test results show that all functions of the system can run normally and basically achieved the preset performance indicators.The system can support 1200 users of concurrent event request processing,the system can be compatible with different versions of browsers,different models of mobile phone systems.
