Abstract

The invention discloses a method for measuring the levelness of ship special equipment. The method comprises the following steps: preliminary preparation; status confirmation before measurement; inspection and detection of measuring instruments; levelness measurement; measurement data processing; establishment of levelness distribution function; measurement results Evaluation and analysis; Equipment horizontal attitude correction. The invention has the advantages of high measurement precision, convenient operation and cost saving.

Description

technical field [0001] The invention relates to the field of ship special equipment installation engineering, in particular to a method for measuring the levelness of ship special equipment. Background technique [0002] As the launch platform of maritime weapons, the ship has many high-precision weapons and electronic equipment such as communication and navigation on the platform. However, whether these equipments can normally meet their strike accuracy and exert their own effects cannot be separated from their own installation platforms (bases), and these bases usually have extremely high precision requirements. [0003] Existing measurement technology is to adopt "half pouf measurement method" or "full floating measurement method". [0004] The disadvantage of the "half pier measurement method" is that the preparatory work is complicated. All contact points between the dock pier and the hull need to be accurately measured and tested underwater, and whether the states of ...
