虚拟试验系统协议转换模块研制

摘要

哈尔滨工业大学自动化测试与控制研究所研发了试验和训练体系结构HIT⁃TENA平台，用于搭建虚拟试验系统；为了将靶场实物资源接入该系统，研制了基于PCI总线和1553B总线的协议转换模块。采用DSP+FPGA的硬件结构，利用FPGA实现了并行协议帧头识别，利用DSP实现了协议转换。测试表明，该模块能完成协议转换，并将延时降低到1 ms以内，解决了试验设备接入虚拟试验系统时转换效率低下、延时较大等问题。%A testing and training architecture HIT⁃TENA platform was developed by Automatic Test and Control Institute of Harbin Institute of Technology to establish virtual test system. In order to connect the testing resourse in the system,a protocol conversion module based on PCI bus and 1553B bus was designed. The logic of 1553B protocol and concurrent protocol identifi⁃cation were achieved on the basis of hardware structure with DSP + FPGA and FPGA. The DSP is used to realize the protocol conversion. The testing result shows the the module can perform the function of protocol conversion and reduce the delay to 1 ms. It solves the problem of low efficiency and long delay occurred when the test equipments join up with virtual test system.
