在深入研究1553B总线协议和总线实现方式的基础上,通过以BU-61580协议芯片为核心设计了原理样机的软硬件系统,原理样机实现了1553B总线协议终端的功能,并结合总线测试卡进行了功能测试。测试结果表明,数据在1553B总线上传输正常,原理样机实现了其BC和RT的全部功能,满足MIL-STD-1553B总线协议的要求。
Based on the thorough research of 1553B bus protocol and bus realization method, the hardware and software system of the prototyping prototype is designed with BU-61580 protocol core as its core. The principle prototype realizes the function of 1553B bus protocol terminal and combines with bus test card function test. The test results show that the data is transmitted normally on the 1553B bus, and the principle prototype realizes all the functions of the BC and RT and meets the requirements of the MIL-STD-1553B bus protocol.
