某高炮火控系统射击诸元采集装置设计

Design of Firing Data Acquisition Device of Antiaircraft Artillery Fire Control System

在高炮火控系统射击校正中,射击诸元需要以数字量形式送入校射系统作为输入信号使用,而高炮火控系统射击诸元大都是采用三相轴角信号形式的模拟信号。为了解决这一问题,设计了一种高炮火控系统射击诸元采集装置实现射击诸元模拟量向数字量形式的转换。首先分析了射击诸元的采集与测量原理,设计了SCOTT变压、采样保持、A/D转换、正峰值脉冲产生、数据处理与控制等硬件功能电路,阐述了采集装置的总体工作过程,在此基础上进行了软件程序设计。该射击诸元采集装置的研制为高炮火控系统射击诸元的采集以及校射工作提供了一种实用的方法。

In the process of shooting amending of antiaircraft artillery fire control system,the firing data needs to be input into the shooting amending system with digital form and used as input signals,but the firing data of antiaircraft artillery fire control system mostly used the form of three-phase axis angle signals which are analog signals.To solve this problem,this paper designs a firing data acquisition device of antiaircraft artillery fire control system to achieve the firing data＇s conversion from analog from to digital form.First,the paper analyzed the firing data＇s collection and measurement principle;and then designed some control circuits such as SCOTT transformer circuit,sample and hold circuit,A/D conversion circuit,plus peak pulse generation circuit,data processing and control circuits;described the overall working process of the acquisition device,and finished the software programming.The design of firing data acquisition device of antiaircraft artillery fire control system provides a practical approach for firing data acquisition and shooting amending work.
