摘要:280-6G型球形指示器电子部件的国产化是利用模拟、数字集成电路对功率放大器模板和故障探测器模板进行研制。功率放大器模板选用LM1875。故障探测模板采用LM4801、LM14001和LM124以实现。研制的电子部件能提高指示器的跟踪速度,降低系统的动、静态电流。同时,还能完成球形指示器与原机陀螺平台和仿形装置的配套工作,精确指示飞机的姿态角和航向角。
Abstract: The domestication of 280-6G spherical indicator electronic components is to develop the power amplifier template and fault detector template using analog and digital integrated circuits. Power amplifier template selection LM1875. Fault detection template using LM4801, LM14001 and LM124 to achieve. Developed electronic components can improve the tracking speed indicator, reducing the system of dynamic and static current. At the same time, but also to complete the spherical indicator and the original gyro platform and profiling device supporting work, precise indication of aircraft attitude and heading angle.
