Problems solved by technology
If there is an error in the secondary marking, it will directly affect the accuracy of subsequent measurement work
In addition, the traditional method requires a large number of personnel to contact the segmented operation, which greatly reduces the safety factor on site, and the obtained positioning and loading data are in two-dimensional form, which makes it difficult to form a three-dimensional overall control of the ship and marine engineering equipment to be built

Embodiment Construction
[0046] Such as figure 1 As shown, the present invention provides a kind of construction method of digital shipyard, comprises the steps:
[0047](1) Carry out on-site survey of the location of the point layout and the dock utilization cycle, design and lay out the reference control points of the digital dock according to the site conditions and shipbuilding progress, and arrange a pair of reference control points at intervals of 40 to 60 meters along both sides of the dock point;
[0048] (2) if figure 2 As shown, the stability monitoring of the reference control point is carried out; a high-precision total station is set up at point A, and peripheral stable points P1 and P2 are selected as monitoring references, and P1, P2, 1, 2, ... n A total of n+2 direction angles, zenith distances, and slant distances. The displacement of each point is obtained by comprehensive calculation of the data of each period; the displacement of each point is calculated by formula (1):

A method for constructing a digital dock, establishing a digital dock, perfectly transforming centerlines, half-width lines, rib lines and other benchmarks into three-dimensional digital space, suitable for loading and positioning of all segments; digital docks are applicable to any ship type, avoiding In the traditional way of operation, the problems of resetting the datum line of the dock due to different ship types are eliminated. In the current serial construction method, only the unified translation of the datum control data of the digital dock can easily realize the positioning and loading, and there is no need to The accuracy will be lost; the safety factor is improved, the dock cycle is shortened, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a construction method of a digital dock. Background technique [0002] A dock is a hydraulic structure used to build ships and marine engineering equipment. During the construction process of ships and marine engineering equipment, they are first constructed in sections in relevant areas such as workshops, and after passing the inspection, they are hoisted to the dock for positioning and loading. As a bottleneck resource, the dock directly determines the production cycle of ships and marine engineering equipment. Ship loading and positioning is an important stage in the shipbuilding process, and improving loading efficiency is a problem that every shipyard is constantly exploring. [0003] At present, domestic large and medium-sized shipyards are equipped with three-dimensional measurement tools represented by total stations. The traditional method of using total ...
