[Abstract]:In order to improve the rapid reconfiguration of the 1553B bus test system when the topology or communication protocol changes, a fast reconfigurable 1553B bus test software design method based on the universal 1553B bus simulation card is proposed. This paper analyzes the shortcomings of the reconfiguration of the 1553B bus test system, and introduces in detail the design framework and implementation method of the fast reconfigurable 1553B bus test software. The software design method proposed here makes the code realization of the software independent of the specific format of the bus protocol by the way of bus service partition and proxy hosting, and greatly reduces the code amount of software programming. So the software can be reconfigurable quickly in both code reconfigurable and configurable reconfigurable. The software design has the characteristics of high reliability, high programming efficiency, fast reconfiguration speed and reconfiguration on the spot. The code reconfiguration rate of the application case software is less than 1 鈥，
