摘　　要：针对基于北斗短报文的特种车辆状态监管系统在实现一对多管理时的通信不稳定问题,特别是多台车载北斗接收机终端同时与数据中心通信引发的并发和丢包,进行通信服务器架构研究。利用多优先级缓冲队列、基于异步IO的线程池管理技术和Java并发库,设计实现了适用于北斗短报文的通信服务器架构,并进行实验测试。结果表明与传统单线程方式和Netty框架相比该架构数据传输时延降低了54.9%和5.2%,丢包率降低了69.2%和6.3%,该架构可以保证重要数据的时效性,较好地解决并发问题,且简单可行易用于工程实践,适用于北斗短报文传输方式。Aimed at the communication instability problem of the special vehicle status monitoring system based on Beidou short messages when implementing one-to-many management,especially the concurrency and packet loss caused by multiple vehicle Beidou receiver terminals communicating with the data center at the same time,the communication server architecture is studied.A multi-priority buffer queue,a thread pool management technology based on asynchronous IO,and a Java concurrency library were used to design and implement a communication server architecture suitable for Beidou short messages,and it was tested experimentally.The experimental results show that compared with the traditional single-threaded method and the Netty framework,the data transmission delay of this model is reduced by 54.9%and 5.2%,and the packet loss rate is reduced by 69.2%and 6.3%.This architecture can ensure the timeliness of important data,better solve the concurrency problem,and is simple,feasible,and easy to use in engineering practice,and is suitable for related applications of Beidou short messages as a transmission mode.
