摘　　要：传统广域网信息访问控制系统由于形成时序图的步骤十分复杂,所以广域网信息访问控制效率低,针对上述问题,基于信息流模型设计了一种新的广域网信息访问控制系统,分别对系统硬件、软件进行优化设计。硬件选取MIX型号的主板作为信息流模型的访问控制收集板,缩短时序图步骤,提高访问效率;选取QU-10型号的驱动器增强系统驱动能力,引用多线程技术提高软件程序执行速度。实验结果表明,基于信息流模型的广域网信息访问控制系统由于引入了网络通信接口,响应时间大大缩短,工作效率高于传统系统。The traditional WAN information access control system has a very complex sequence of steps,so the WAN information access control efficiency is low.In view of the above problems,a new WAN information access control system is designed based on the information flow model.Optimized design,the hardware selects the MIX model of the motherboard as the access control collection board of the information flow model,shortens the timing diagram steps,improves the access efficiency,selects the QU-10 model of the driver to enhance the system driving capability,and uses the multi-thread technology to increase the speed of software program execution.The experimental results show that the WAN information access control system based on the information flow model introduces a network communication interface,the response time is greatly shortened,and the working efficiency is higher than the traditional system.
