摘要
视频分划生成技术是测瞄合一的光电瞄准具的核心技术之一。视频分划设计除了有十字分划之外 ,还有圆分划和椭圆分划。在各种参数传感器或弹道计算机发生故障时仍可用圆分划和椭圆分划来完成对目标的搜索、瞄准 ,增强测瞄合一的光电瞄准具的可靠性及生命力。选用可编程 CPL D器件作为核心控制器 ,用 VHDL语言对其进行编程 ,可配合使用 EPROM、同步分离器、视频叠加器、电子开关等。整个设计使用的芯片少 ,稳定性好 ,易于调试和功能扩展 。
This video graduation generate technology is one of the core technology of photoelectric aimer Besides cross graduation, this video graduation design includes round and ellipse graduation When parameter sensors or trajectory computer is wrong, it can also track and aim the object, providing for aimer's aim It enhances the reliability and vitality of the photoelectric aimer CPLD is selected as the main controller It can be programmed in system with VHDL language It is assorted with other assistant devices, including EPROM, synchrodivision circuit, video overlayer, relay and so on With few chips, easily being debugged and being extended, this video graduation figure generator can satisfy the design request
