摘　　要：在C/S模式下,车载终端的并发接入量是检验GPS车辆监控系统服务器性能的重要因素。为了满足大量终端的并发连接请求并快速响应用户操作,首先采用三层体系结构设计服务器,增强系统的可扩展性,实现模块间高内聚低耦合。其次对服务器接入模块部分应用IOCP模型进行优化,针对实际应用中信息定位、多类型终端接入、资源优化管理、数据正确性等问题,分别采取缓冲链表、内存池以及分包策略等方法进行有效解决。最后在实际应用项目中进行测试,实验结果均表明优化后的服务器性能和稳定性具有明显的改善。Under C/S mode , concurrent access quantity of the car-mounted terminal is the significant factor to test GPS vehi-cle monitor system capacity . To satisfy concurrent access request of a mass of terminals and to rapidly respond to users ’ operation , firstly , this article adopts server with three structure design to strengthen the system expandability and to realize high cohesion low coupling between modes . Secondly , it uses IOCP mode to optimize the part of server accessing to mode . Aiming at information por-tioning , multi-type terminal access , resource optimization and management and the statistics correction , etc problems in practical adaption , it takes the measure of buffering links , storage pools and package strategy to effectively solve above problems . After all , to test in practical project and then the result shows there are obvious improvements on the serving ability and stability .
