A320模拟机遮光板的模块化设计与实现

Building Blocks Design and Implementation of Glareshield for A320 Simulator

提出了一种模拟机遮光板的模块化设计方法。该方法在归类系统功能的基础上,通过适当降低操作板与控制板模块间的相对依赖性连接,实现功能与结构的分离、模块的再分割以及数据在各模块间的通信,进而达到独立功能模块设计的目的。进一步,以模块间的通信为例,设计了独立的通信模块,通过加入斯密特触发器而有效抑制了由于通信乱码而致死机的频繁发生。在实际应用中,通过操作实验,证实了该模块化设计方法可大大提高模拟机遮光板通信的可靠性;同时该方法也可用于模拟机前头顶板和中央操纵台的设计中。

A building block approach is presented to design Glareshield of a simulator. On the basis of its function categorization, this approach aims at designing independent functional blocks through appropriately lowering relative dependence on connections between blocks of operating board and control board, realising separation of function and structure, module segmentation and data communication between modules. Furthermore, taking communication between blocks as an example, independent communication blocks were de- signed, which effectively prevented frequent occurrence of system crashes due to code disorder in communication. Through experiments in applications, it proves that the building block design approach can greatly improve the reliability of the simulator. Furthermore, this approach could also be applied in the design of front roof and center control console.
