德国水声和地球物理研究所研制的一种装置可以连续地测量水雷被泥沙掩埋的过程。此种装置的形状和质量与圆柱形沉底水雷相同。水雷壳体配用三个箍带,每条箍带上有24个光垒。光垒的状态(打开或闭合)表示该光垒是在海底面以上或以下。该信息可由光纤传输,并通过照相存储。这种掩埋记录水雷(BRM)是自容式的,并可以记录水雷掩埋过程数周,甚至几个月。
A device developed by the German Institute of Acoustics and Geophysics can continuously measure the process of mines being buried by sediment. The shape and quality of this device is the same as that of a cylindrical sink mine. The mine casing is equipped with three bands, each with 24 light barriers. The state of the light barrier (open or closed) indicates that the light barrier is above or below the sea floor. This information can be transmitted by optical fiber and stored by camera. This Buried Records Mine (BRM) is self-contained and can record mine landfill processes for weeks, or even months.
