Research And Implementation Of Key Technologies In Campus Information Instant Push Platform

Abstract:The rapid development of mobile internet technology and mobile intelligent equipment promotes the campus information innovation. The design of the existing popular instant messaging system, memo system and schedule management system and other mobile applications is not suitable for the campus community. Based on the above research, this paper designs and implements the campus information instant push platform, using transparent calculation principle and supporting multiple terminals, convenient and personalized content distribution.Considering device diversity, power consumption, network flow consumption and message realtime in mobile devices, an adaptive message pushing strategy in mobile network is proposed. In the strategy, the running parameters of mobile device are obtained to determine the message pushing mode, and then the dispatching module will automatically convert the approach between the polling based and the connection based communication. Experiment results show the strategy can solve the terminal diversity problem, ensure the message realtime and save the power and network flow consumption in comparison to some traditional message pushing strategies.Based on the feature that the data comes from the school department, HttpURLConnection is used to implement data integrity, data reuse and software reuse. TimerTask is used to regularly update requested data in the database in order to reach data synchronization and transparent. At the same time, we use configuration file to describe the permission and use proxy pattern to separate permission control module and software implementation, which improves the safety and extensibility of the software.Finally, we test the functionality and performance of this platform in a real condition. The results show that the platform can achieve the anticipated function and the key technologies proposed in this paper ensure the platform pushing news timeliness, integrity, and transparency of the user experience.There are37figures,9tables and56references in this thesis.
