本文给出的是瞄五雷达自整角机随动系统,多路模拟信号数据采集的输入接口设计。为了保证精度,本设计采用了区间判别法和粗精读数组合法。在线路中还采用了极性锁存和峰值脉冲采样等措施。并用特殊的查表技术,有效地提高了系统运行速度。 本接口设计,经空军靶场实弹射击试验,表明接口运行稳定,精度可靠,连接方便灵活。文中提出的设计方法,可供有关系统接口设计时参考。
This article gives a five-radar synchro servo system, multi-channel analog signal data acquisition input interface design. In order to ensure the accuracy, this design uses the interval discriminant method and the crude intensive reading array method. In the circuit also uses a polar latch and peak pulse sampling and other measures. And with a special look-up table technology, effectively improve the system speed. The interface design, the Air Force shooting range live fire test shows that the interface is stable, accurate and reliable, convenient and flexible connection. The design method presented in this paper is available for reference to the design of the system interface.
