摘　　要：在卫星电子设备测试系统中,地面测试软件不仅要访问测试系统硬件,而且需要与用户直接交互,并完成测试数据的存储和管理,并发处理能力是测试系统可靠和正确的关键,传统软件设计采用的串行策略无法适应卫星地面测试软件中的并发处理需求.为解决上述问题,提出多线程、消息机制、共享缓冲区、P-V操作4种并发机制相结合进行程序设计的方法.实际应用表明采用这种基于多种并发机制的程序设计方法能可靠实现卫星地面测试软件,有效解决了软件开发中的并行性问题.In satellite electronic device testing systems,the ground testing software shall access testing system hardware,exchange information with users,and implement test data storage and management simultaneously,the concurrent processing capability of the testing software is the key technique to guarantees the reliability and the validity of the testing system.The sequential programming methods used in traditional software design can not meet the concurrence processing requirement in the satellite ground testing software.In order to resolve the above mentioned problem,a programming method combined with four concurrence mechanisms,multi-thread,message mechanism,shared buffer,and P-V operation,is presented in this paper.Practical application shows that the multi concurrence mechanism based software design method can implement satellite ground testing software reliably,and resolve the parallelism problem in software development effectively.
