摘　　要：半实物仿真试验测试系统以VxWorks实时操作平台为测控核心,详述了系统架构和软硬件组成。对伺服配套单元、试验控制中心等硬件模块及系统程序架构、软件信息流、实时数据采集软件、远程控制软件及终端软件等软件模块做了重点介绍。解决了运载型号仿真状态众多,仿真试验的高速实时性要求以及模拟火箭全程飞行状态等3个关键问题。试验表明,反射内存网络实时性良好,各控制输出和信号采集实现实时传输,系统软件运行稳定可靠,达到预期设计目的。The carrier rocket flight simulation measurement system is proposed, VxWorks real-time operating system is taken as measurement and control core. Software/hardware components and system framework are expatiated. Servo equipment system, experimentation control center, system program framework, software information flow, real-time data sample, remote control, terminal software are introduced in detail. The three key technologies are many carrier rocket flight models, high speed real-time requirement, and entire flight simulation, are solved. The experiment indicates the good performance of reflected memory network, and real-time transmission of each control output and data acquisition, and the software running is stable and reliable. Conclusively, anticipative design intention is achieved.
