摘　　要：提出并描述了多线程通讯服务模型的设计和实现方法,该模型充分利用面向对象理论将交通诱导系统中嵌入式外场设备、通讯服务中心与监控客户端和他们之间的通讯过程分别进行了模型抽象和系统实现。对比之前的监控机单点监控模型,能够更好的解决多监控机在多网络连接内与多类型外场设备的实时通讯控制问题。同时,相对于单线程和双线程通讯模型,通过系统运行测试,该多线程模型有效的解决了由于个别通讯故障引发的整体系统轮询等待滞后问题,缩短了整个轮询和控制通讯周期。This paper presents and describes the design and implementation of multi- threadedcommunications services model. By using of object-oriented theory, the model describes the relationshipand the communication process abstractly between communications server, control clients and embeddedfield equipment. Comparing the model of single monitoring – it can give a better solution ofcommunication and control between multi-monitor and multi-field equipment through the multi-typenetwork. At the same time, as opposed to single-threaded and dual-thread communication model, thesystem effectively solves the problem of system polling and commands sending. And it shortens the entirecycle of polling communications.
