Problems solved by technology

However, at present, when laying cables in nuclear power plants, the cable laying path is not planned in detail, and the reasonable distribution of cable channels cannot be effectively controlled. It is completely carried out by the construction experience of the on-site construction unit, and the blindness is large. The length of the cable is manually estimated according to the layout of the plane channel, resulting in a huge difference between the cable length and the estimated length, low design efficiency and large errors; and the location information of the field equipment is incomplete. Lack of instrument positioning information in the design stage often leads to re-laying due to unreasonable cable laying, causing investment waste and affecting project progress

Abstract

The invention relates to a design method for cable laying and a cable laying system. The method comprises following steps: creating a three-dimensional model for a cable channel; setting up a cable channel model database; planning layers of the cable channel, the number of layers of the cable channel and the arrays of the cable channel, and encoding the cable channel in a segmented manner, arrays and layers; setting up an equipment positioning database; planning positions of a measuring instrument and control equipment on the spot; guiding the cable channel model database and the equipment positioning database into cable laying software and inputting setting value; and finishing a best cable laying path design after a cable laying path list is automatically generated by cable laying software. The design method for cable laying and the cable laying system have following beneficial effects: by automatically generating the cable path list, deign efficiency is increased; by effectively planning the cable laying path, cable bridges can be reasonably distributed; the problem of repeatedly laying due to unresonable laying of circuits is eliminated; investment waste is avoided; engineering speed is ensured; a clear cable path is provide for a foundation of precise cable length calculations.

Description

technical field [0001] The invention relates to the technical field of cable laying, in particular to a cable laying design method and a cable laying system. Background technique [0002] The cable is a bridge connecting the control system and the controlled equipment. The cable laying path is reasonable to ensure reliable signal transmission and safe operation of the power plant. However, at present, when laying cables in nuclear power plants, the cable laying path is not planned in detail, and the reasonable distribution of cable channels cannot be effectively controlled. It is completely carried out by the construction experience of the on-site construction unit, and the blindness is large. The length of the cable is manually estimated according to the layout of the plane channel, resulting in a huge difference between the cable length and the estimated length, low design efficiency and large errors; and the location information of the field equipment is incomplete. The ...
