摘要
针对当前考试系统集成性不好、数据吞吐和系统响应性能较差等问题,提出基于多平台跨区域网络环境的考试系统设计方法。系统采用PCI总线技术进行多平台环境下的考试信息传输和资源调度,采用多通道串口技术进行网络输入输出接口设计,在跨区域的网络考试进程中提供全双工的通信机制,在CCS 2.20开发平台下实现考试系统的软件开发设计。系统测试结果表明,该系统能提高考试的信息调度能力,吞吐量较大,系统的响应时间较短,考试系统具有较高的运行可靠性。
Aiming at the problems of poor integration, poor data throughput and poor response performance of the current test system, an examination system design method based on multi-platform cross regional network environment is proposed in this paper. The PCI bus technology is used system to perform the exam information transmission and resource scheduling in multi- platform environment. The multi-channel serial technology is adopted to design network input and output interfaces to provide full duplex communication mechanism in the process of the cross regional network exam, and realize design and development of the exam system software in CCS 2.20 development platform. The system test results show that the system can improve the infor- mation scheduling ability, increase the throughput and shorten the system response time. The exam system has high operating reliability.
