瞄准线稳定系统和自寻北定向系统对于坦克等陆地战车是非常重要的。文中针对目前大多数战车都装有瞄准线稳定系统的这一情况 ,在原有稳瞄平台的基础上 ,增设加速度计等相应设备 ,并加以计算机控制。由于辅加的加速度计和原系统中的陀螺仪分别可感测重力加速度和地球自转角速度 ,从而就可进行水平调平和方位的解算 ,使得系统同时具有稳定跟踪功能与寻北定向功能 ,构成组合平台。文中采用了双位置寻北解算方位角 ,着重讨论了单动调式陀螺所构成的寻北系统及其特征 ,并分析制定了转位的控制方案。仿真表明 ,该方案是可行的。
The line of sight stabilization system and the self-made North Orienteering System are very important for land tanks such as tanks. In view of the situation that most tanks are equipped with sight line stabilization system, the corresponding devices such as accelerometers are added on the basis of the original stabilized sighting platform and computer controlled. As the additional accelerometer and gyroscope in the original system can respectively sense the gravitational acceleration and the angular velocity of the Earth’s rotation, leveling and azimuth solution can be carried out so that the system has both stable tracking function and north-seeking directional function, Combination platform. In this paper, the azimuths of dual position finding north are used to solve the problem. The north seeking system formed by single-acting gyroscope and its characteristics are mainly discussed, and the control scheme of indexing is developed. Simulation shows that this scheme is feasible.
