多接口实装资源实时接入代理设计与研制

Design and Development of Multi-Interface Real-Time Access Agent for Equipment Resources

提出了基于嵌入式系统架构的通用实装资源实时接入设备的设计方案。采用通用硬件接口及软件框架,通过设计现场可编程阵列(FPGA)和数字信号处理器(DSP)程序以及协议转换模块和中间件模块,使用户只需编辑通信协议即可将实装资源接入虚实合成试验系统中。最后采用多种方法对代理进行实时优化设计并完成测试,结果表明代理设备性能指标满足系统接入要求。

A design scheme of real-time access device based on embedded system architecture is proposed. Using common hardware interface and software framework,users only need to edit communication protocols to implement resources access to a live virtual and constructive（ LVC） test system with the design of field programmable gate array（ FPGA） and digital signal processor（ DSP）procedures,protocol conversion modules and middleware modules. Finally, some methods are adopted to optimize the real-time access agent and the corresponding tests are conducted. The results show that the performance of the device meets the requirements.
