The invention relates to an anti-overturning seabed magnetic survey base station with a precise leveling function. A welding frame is of a pyramid structure, a magnetic measurement sealed cabin is arranged in the middle of the welding frame, and a fender is arranged on the side face of the welding frame. The MEMS gyroscope and the MCU are arranged in the magnetic measurement sealed cabin, and an underwater hydraulic lifting device is arranged on the bottom face of the welding frame and connected with the MCU through a circuit. The MCU adopts a criterion weight method to identify a time sequence model with an intercept item of the random error of the MEMS gyroscope, the attitude of the magnetic measurement base station at the moment is obtained after data is corrected online, and finally the attitude of the magnetic measurement base station is corrected by controlling the underwater hydraulic lifting device. According to the invention, the structure is stable, accurate leveling can be realized, the calculation complexity is low, and few calculation resources are consumed during operation.

    本发明涉及一种具有精准调平功能的防倾覆海底磁测基站。本发明焊接框架采用金字塔结构,磁测密封舱设置在焊接框架中部,在焊接框架的侧面设置有挡泥板。MEMS陀螺仪和MCU设置在磁测密封舱内,焊接框架底面设置有水下液压升降装置,水下液压升降装置与MCU通过线路连接。MCU采用准则权值法辨识MEMS陀螺仪随机误差的具有截距项的时间序列模型,将数据进行在线修正后,得出此时磁测基站的姿态,最后通过控制水下液压升降装置,对自身姿态进行校正。本发明结构稳定,能够实现精准调平,且计算复杂度低、运行时消耗的计算资源较少。
