为快速反求飞机某产品输入信号在其1553B总线通信协议中的软件位置(包括远程终端子地址、数据字编号等信息),在对1553B总线信号接口定义反求进行系统诠释的基础上,利用一台PCI工控机、多张1553B总线板卡,搭建出反求硬件平台,针对美国Condor公司1553-PCI卡,基于VB6.0开发出全局搜索软件,并基于扰动法将该软件应用于该产品进行了实验验证。实验结果表明,所开发出的全局搜索软件不仅可以提高反求效率,而且其反求思路可广泛应用于反求飞机其他产品1553B总线信号接口定义的反求。
In order to quickly reverse the software position (including remote terminal sub-address, data word number and other information) of a product input signal in its 1553B bus communication protocol, based on the reverse interpretation of the 1553B bus signal interface definition, A PCI industrial computer, a plurality of 1553B bus cards, build an anti-hardware platform for the United States Condor’s 1553-PCI card, based on VB6.0 to develop a global search software, and based on the perturbation method to apply the software to the product Experimental verification. The experimental results show that the developed global search software can not only improve the reverse efficiency, but also can be widely applied to reverse the definition of 1553B bus signal interface of other aircraft products.
