Loop Dynamic Precision Test Method for Fire Control System

借鉴环绕BIT技术的思想,提出一种火控系统动态精度环绕测试的设计方法。该方法充分利用火控计算机的固有资源,通过增加少量接口转换电路(一组现在点坐标输出接口和一组射击诸元输入接口),来提高火控系统动态精度检查测试性水平。对于采用环绕测试设计的火控系统,只需使用两根外接电缆,无须外接检测计算机,即可完成动态精度检查的任务,从而显著降低了操作复杂性。该设计方法的一个优点是不会影响系统的可靠性。

Presented is a loop dynamic precision test method for fire control system, which lends its idea from the loop BIT technique. The proposed method, making advantage of the resource of the fire control computer, successful improves the testability level of dynamic precision test for fire control system by adding a little of interface circuits. The interface circuits include a group of circuits for outputting present target coordinates and a group of circuits for inputting projecting parameters. For fire control system using the proposed method, the task of dynamic precision test could be conducted easily by connecting two wires, and without the use of a testing computer. The proposed method can significantly reduce the operating complexity of the dynamic precision test and will not affect the reliability of a system.
