摘　　要：线程池技术广泛用于解决服务器并发访问效率问题,但在航空、航天的嵌入式系统中则运用较少。为了解决传统嵌入式软件运效率较低和可维护性较差的问题,开发一种基于线程池技术的流程调度框架。详述该框架的逻辑架构、各模块具体功能、关键技术、应用方式以及典型应用场景。该框架通过流程定义,可快速重组流程,并使代码维护简单;基于线程池技术,可提高软件执行效率;通过流程跟踪和统计,可监控流程运行。Thread pool is widely used for improving the efficiency of server’s concurrent access,but application on embedded system of aerospace is less mentioned.In order to improve the effi-ciency and maintainability of common control software,a flow schedule framework is developed based on the thread pool.The framework’s logic architecture,function of different module,key technology and typical application scenarios is discussed in detail.Based on flow definition,the flow recombination and code maintenance can be implemented easily.Based on the thread pool,the software’s efficiency can be improved.Based on flow trace and statistics,the software’s run-ning process can be traced.
