【摘要】 MIL-STD-1553B（以下简称“1553B”）总线在飞机的航电系统中作用重要。为了摆脱对国外1553B协议芯片的依赖，研究设计了1款基于FPGA的终端一体化1553B总线协议测试系统。系统采用模块化的设计方法，使用Verilog语言进行代码编写，设计实现了4路1553B总线，每路实现了BC、RT、BM终端一体化，完整地实现了1553B协议的功能，并且实现了10种类型的故障注入。通过上位机测试对该系统进行了板级验证，测试结果表明：本设计实现了预期功能，相对于功能单一的1553B协议芯片，该系统极大提高了应用场景的灵活性和可靠性。更多还原

【Abstract】 The 1553B bus plays an important role in the avionics system of the aircraft. In order to get rid of the dependence on foreign 1553B protocol chips, a terminal integrated 1553B bus protocol test system based on FPGA is designed.The system adopts modular design method, uses Verilog language to write code, designs and implements four 1553B buses, each of which realizes the integration of BC, RT and BM terminals, fully realizes the functions of 1553B protocol,and realizes ten types of fault injection. The system is verified at the board level through the upper computer test. The test results show that the design has achieved the expected functions. Compared with the single-function 1553B protocol chip,the system greatly improves the flexibility and reliability of the application scenario.更多还原
