摘　　要：机载数据记录仪由于自身处于较为复杂且变化莫测的机载环境中,经常会出现数据失真、数据不连续和数据丢失等问题,影响数据传输的准确性、稳定性和完整性,难以发挥机载数据记录仪的真正作用。因此,结合当前记录仪中总线通信存在的问题,进行机载数据记录仪1553B总线接口的硬件设计。测试证明,该设计能够更加准确、稳定且完整地进行数据传输,并及时响应。Airborne data recorder because itself in a more complex and the vagaries of airborne environment, often appear distortion as well as the discrete data, the problem such as lost, will affect the accuracy, stability and integrity of data transmission, it is difficult to play a real role of airborne data recorder. Therefore, this article combined with the problems existing in the current bus communication of recorder, airborne data recorder of 1553 b bus interface of the hardware design, and through the test validation, proved that the design can be more accurate, stable and complete for data transmission and timely response.
