基于Websocket的车联网报警推送系统

Telematics Alarm Pushing System Based on Websocket Protocal

报警处理是车联网系统中的重要功能.传统车联网系统一般采用AJAX轮询的方式定时拉取报警信息,既不能保证报警实时性和准确性,也给服务器造成压力.本文设计了一种基于Websocket,Redis等技术的报警实时推送系统,并对推送性能做了测试和分析.结果表明:使用Websocket推送方式处理报警信息,既提高了报警的实时性和准确性,又提高了推送的吞吐量,降低网络流量.

Alarm processing is fundamental function in Telematics System.AJAX pulling is common method in traditional system.But AJAX pulling is not real-time communication,and the server suffers unnecessary requests.In this study,we design a telematics alarm pushing system based on Websocket and Redis.Then,we test this system.The results show that Websocket is an ideal technology for alarm pushing.It improves network throughput,reduces latency and network traffic.
