摘　　要：为了解决采用i.lon SmartServer进行数据采集时所遇到的问题,改善其工程应用的效果,在对这些问题进行分析的基础上,提出了一种高性能数据采集解决方案。该方案基于中间件的设计理念,采用层式多线程模型建立核心框架,设计了一种分层容错调度算法和一种基于统一编码的数据映射机制。综合运用了数据缓存、数据备份、消息队列等技术,并通过使用Java实现了采集系统。最后通过测试中的表现和实际工程项目中的应用情况表明了该解决方案的高效性、稳定性和安全性。To solve the problems encountered by using i.lon SmartServer （Lion in abbreviation） in data acquisition, and improve the effectiveness of its engineering application, a high-performance data acquisition solution, is proposed based on the analysis of these issues. Firstly, the core framework is built based on middleware design concepts, using hierarchical multithreading model. Then, a hierarchical fault-tolerant scheduling algorithm and unicode-based data mapping mechanism are designed. Finally, data buffering, data backup, message queues and other technologies are integrated used. The acquisition system is implemented by Java, The performance in testing and practical application of engineering projects demonstrated the solution＇ s efficiency, stability and security.
