线导鱼雷模拟器的改进设计

为了满足作战训练需求,对某型线导鱼雷模拟器进行了改进设计.模拟器的设计基于复杂可编程逻辑器件(CPLD)和C++ Builder,采用“工控机+ISA总线+CPLD+上位机软件”结构.在分析了已列装的该型鱼雷模拟器所存在的缺陷基础上,提出了新型模拟器的功能需求以及总体设计方案,根据功能需求,从硬件和软件两方面对模拟器进行设计:硬件部分包括接口电路以及联接ISA总线和接口电路的桥接电路;软件部分采用C++ Builder进行开发,通过Win IO函数实现对底层硬件的驱动.改进后的模拟器在试用过程中取得了良好的效果,其主要技术性能达到了设计要求.

Improvement of Wire-guided Torpedo Simulator

To meet the requirement of battle and training, the conventional wire-guided torpedo simulator was improved. The improvement is based on complex programmable logic device （CPLD） and C＋＋ Builder, and adopts the structure of ＂industrial personal computer（IPC）＋ISA bus＋ CPLD＋ personal computer（PC） software＂. By analyzing the shortcomings of the conventional simulator, the functional requirement and general design scheme of the improved simulator were put forward. The improvement concerns two aspects： 1） an interface circuit and a bridge circuit used for connecting the interface circuit and the ISA bus are employed for the hardware; and 2） the software is developed＇with the C＋＋ Builder to drive the hardware through the Win IO function. This improved wire-guided torpedo simulator showed satisfactory effectiveness in trial stage, and its main performance parameters met the design requirement.
