摘要
航姿测量系统可以采集船舶的航向、方位、水平姿态等信息,对船舶导航、舰载飞行器着舰、导弹引导等有重要的作用。传统的船舶航姿测量采用陀螺仪等传感器件,通过采集船舶的角速度得到姿态角,该测量方式的动态特性好,但存在成本高、集成度低、自动化程度低等问题。随着嵌入式芯片和微机系统的发展,基于嵌入式处理器的船舶航姿测量系统被开发出来,该类型的航姿测量系统具有精度高、功耗小和自动化程度高的优点,应用越来越广泛。本文基于嵌入式芯片,设计和开发了基于微机电系统的船舶航姿测量系统,并对该系统的结构组成和工作原理进行介绍。
Attitude measurement system can collect ship's course, azimuth and horizontal attitude, and it plays an important role in ship navigation, carrier aircraft, landing ship, missile guidance and so on. Ship attitude measurement using the traditional gyro sensor, the angular velocity acquisition ship attitude measurement, dynamic characteristics of the way is good, but there are some problems such as high cost and low integration degree, low degree of automation. With the development of embedded chip and microcomputer system, ship navigation attitude measurement system is developed based on embedded processor, this type of AHRS has advantages of high precision, low power consumption and high degree of automation, more and more widely used. Based on embedded chip, a ship attitude measurement system based on MEMS is designed and developed, and the structure and working principle of the system are introduced.
