摘　　要：针对车辆管理系统在新旧系统衔接过程中出现的问题,以数据中转服务器为基础,构建了用于新旧系统衔接的框架;在该框架中,采用高性能Netty架构实现了大规模并发车辆数据的实时接收与转发;采用协议转换的技术解决了新旧系统通讯协议不一致的问题;采用数据缓存配合延迟入库的方法对大规模车载传感信息的实时接收、动态表达和批量入库进行了实现;实例表明,该方法能够很好地实现新旧系统的衔接,并有效地解决了衔接过程中数据并发、协议转换、批量入库等问题。Aims at the problems in the process of connecting the new and old systems of the vehicle management system,based on the data transfer server,a framework for connecting the old and new systems is constructed.In this framework,the high-performance Netty architecture is used to realize the real-time collection and transferring of large-amount concurrent vehicle data;the protocol conversion technology solves the problem of inconsistent communication protocols between the new and the old systems;the method of data caching and delayed storage is used to achieve large-amount concurrent vehicle sensor data real-time collection,real-time expression and batch storage.Application examples show that the system can well support the connection between the old and the new system,and effectively solve the problems of data concurrency,protocol conversion,and batch storage in the connection process.
