Abstract
The present invention relates to a kind of roof distributed photovoltaic system laying method based on BIM technology, include the following steps: one: simulating real illumination according to longitude and latitude and using BIM technology, illumination is found out in occlusion area horizontal, in vertical direction, then determines the region area that photovoltaic system can be laid；Two: determining the square matrix number of each roofing installation photovoltaic panel；Three: determining the number, amount of capacity and installation site of inverter and header box；Four: using BIM technology, determine trend, quantity, length and the arrangement of cable and cable testing bridge, and show by three-dimensional stereo model.Present invention removal is blocked, plate-laying one-time-reach-place, is quickly found out shortcoming in design and is adjusted in time, so that generated energy is reached maximization, improve design work efficiency.
Description
Technical field
The present invention relates to a kind of photovoltaic system laying methods, specifically the roof distributed photovoltaic based on BIM technology
System laying method.
Background technique
With the national high speed development of new energy field and the subsidy policy of government in recent years, new energy photovoltaic industry
Be widely used and Building Trade in China new technology spread application emphasis.It has emerged several different forms,
It is most for being used with monocrystalline silicon, polysilicon.However the design method of designing institute all uses the form of two-dimentional drawing at present, for face
Huge, many and diverse photovoltaic project of system of product, carrying out construction using two-dimentional drawing will appear some difficulties and problems.It is especially electrical
The arrangement quantity of drawing, cable and gantry is more, should not distinguish in drawing, needs repetitious interpreting blueprints, brings to construction
It is inconvenient.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, a kind of roof distributed photovoltaic system based on BIM technology is provided
Laying method, by three-dimensional stereo model, perception is strong, and visualization is high；
In order to solve the above-mentioned technical problem, the present invention is implemented as follows:
A kind of roof distributed photovoltaic system laying method based on BIM technology, it is characterised in that it includes the following steps:
Step 1: simulating real illumination according to longitude and latitude and using BIM technology, finds out illumination in screening horizontal, in vertical direction
Gear region just can determine that the region area that photovoltaic system can be laid after determining illumination shielded area；
Step 2: according to size, type and the capacity of the region area selection photovoltaic panel laid determined, thus really
The square matrix number of each roofing installation photovoltaic panel is determined；
Step 3: according to the square matrix quantity of each roofing photovoltaic system determine the number of inverter and header box, amount of capacity with
And installation site；
Step 4: BIM technology is used, the trend of cable and cable testing bridge, number are determined according to inverter, header box number and position
Amount, length and arrangement, and showed by three-dimensional stereo model.
The beneficial effects of the present invention are: converting three-dimensional stereo model for traditional two-dimentional drawing using BIM technology, simulate
True illumination and angle, exclude shadow region, quick plate-laying, and can express statistic component material information, including quantity,
Length, material, weight etc..Two and three dimensions plan view is generated by model, quickly goes out to scheme.Construction personnel is allowed more intuitively to see
Each specific three-dimensional shape of component, arrangement and trend including cable and gantry, it is easier to understand, accomplish to know what's what.Pass through
Model is constantly updated and optimized, design drawing is optimized, construction efficiency is improved, shortens the construction period, reduce cost.
Specific embodiment
A kind of roof distributed photovoltaic system laying method based on BIM technology, it includes the following steps:
Step 1: it is simulated according to longitude and latitude locating for Shanghai City (longitude: 121.29 °, latitude: 31.33 °), and using BIM technology
Real illumination, find out illumination Winter Solstice that afternoon three o'clock sharp illumination occlusion area, after determining illumination shielded area, energy
Determine the region area that photovoltaic system can be laid；
Step 2: according to size, type and the capacity of the region area selection photovoltaic panel laid determined, thus really
The square matrix number of each roofing installation photovoltaic panel is determined；
Step 3: according to the square matrix quantity of each roofing photovoltaic system determine the number of inverter and header box, amount of capacity with
And installation site；
Step 4: BIM technology is used, the trend of cable and cable testing bridge, number are determined according to inverter, header box number and position
Amount, length and arrangement, and showed by three-dimensional stereo model.
