| 摘 要： | MIL-STD-1553B总线具有实时性、确定性和高可靠性,广泛应用于航空、航天、舰船、坦克等安全、任务关键平台,但其传输率已不能满足日益增长的高传输率需求。针对实际1553B总线系统中存在的大量零元素和数据传输前后变化比例较小的情况,提出了基于软件的数据压缩编码以有效提高实际的数据传输率。分析了零跟踪编码、众数跟踪编码、游程编码、改进型游程编码和差分编码的设计方法,并给出了在现有1553B总线上消息传输中的压缩编码应用。

| Abstract: | MIL-STD-1553B bus is widely used in security and mission-critical platform of aviation,aerospace,ships,tanks with its real-time,determinacy,and high reliability,but its transmission rate can not meet the growing demand for high transfer rate.For the transfer data has a significant number of zero values and a significant number of message values do not change in consecutive transmissions of real 1553B bus system,it is provided data compression encoding based on software to effectively improve the actual data transfer rate,The design of data compression of zero-tracking encoding,common-value tracking encoding,run-length encoding,improved run-length encoding and differential encoding is analyzed,and the application of all compression algorithms in message transfer on the existing 1553B bus is given. |
