Abstract: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.
