本文介绍一种火控系统的系统接口改进方案。这种接口方式不同于经典的三相同步机、感应移相器的角位传感方案,而是基于两相激磁旋转变压器组成移相器的原理,使接口更适于与微处理器配合,简化信号的传输与转换,革除机电系统,达到火控系统输入、输出的标一化。这种方案的原理及关键性技术已在实验中得到证实。 This article describes a fire control system interface improvements. This interface mode is different from the classic three-phase synchronous machine, sensing phase-shift sensor sensing scheme, but based on two-phase excitation resolver phase shifter principle, the interface is more suitable for cooperation with the microprocessor, Simplify the signal transmission and conversion, get rid of mechanical and electrical systems, to achieve fire control system input and output standardization. The principle of this scheme and the key technologies have been confirmed in the experiment.
