数字式射击瞄准计算机设计与实现

Design and Implementation of a Digital Shotting-collimation Computer

某型射击军械系统的射瞄计算机原采用模拟机电式技术实现,存在体积大、功耗大、可靠性及可维护性差等缺点,因此,使用数字式计算机技术对其进行升级改造势在必行。本文首先对原系统的火控原理及火控构型的进行了分析;其次,介绍了射击瞄准计算机的对外接口关系。重点介绍了数字式射击瞄准计算机的采样解算时间的确定、计算方法的选取及接口设计等内容。本文所设计的数字式射击瞄准计算机已通过了系统验证并得到了使用,克服了原有系统所存在的固有缺点。文中的设计思想与所用的工程方法对类似武器系统的升级改造有所借鉴。

An originally Shotting - Collimation Computer of an ordnance system traditionally adopts an analog - mechanical technique, whieh has many disadvantages such as large volume, high power, poor reliability and maintainability. Therefore, it is imperative under the situation to replace it by digital techniques. The paper firstly analyses the fire control principle and structures of the ordnance system. The paper mainly focuses on the confirmation of sample computing time, selection of computing methods and the interface design, etc. The digital Shotting - Collimation Computer has been validated in the system, and overcomes the drawbacks of the original system. The method recommended in the project could make a reference to similar weapon systems.
