Development And Research On Management System Of Sunlight Greenhouse Project Cost

Solar greenhouse is a type of facility agriculture independently researched and developed by our country.In recent years.solar greenhouses have adhered to the development principle of green and rich peasants and are gradually expanding their use area.However.due to various reasons.the development of solar greenhouses in my country is still relatively slow.With the development of the times.people’s needs for technology.life.materials.etc.are also gradually increasing.The development of agriculture will always be an issue that must not be ignored in people’s livelihood.In the field of facility agriculture.which is most compatible with the public.its corresponding development is gradually approaching the direction of high efficiency.high quality and low cost.but the research on the field of solar greenhouse engineering cost is still blank.This thesis combines my own knowledge and uses C# software as the main tool to combine the solar greenhouse in facility agriculture with the engineering cost industry.and make up for the vacancy of facility agriculture in the engineering cost industry.The main research work of this paper is as follows:(1)Focusing on the status quo in the field of solar greenhouse and engineering cost.analyze the problems and related parameters of the solar greenhouse cost management system.According to the results of the demand analysis.the process of the construction cost of the solar greenhouse is designed.The system can be divided into a quantity calculation module and a quota calculation module.According to the calculation module of engineering quantity.the solar greenhouse can be divided into five parts: foundation.wall(gable and rear wall).roof truss.and covering material.According to the calculation rules of civil engineering quantity.the engineering quantity of the foundation and rear wall of the solar greenhouse can be carried out.For the gables.roof trusses and covering materials of solar greenhouses.due to the irregular shape of the gables.it is necessary to use the n-order Bezier curve to determine the function equations of the gables of the solar greenhouse through the start point.end point and control points.and then use Integrate the equation to get the area of??the gable.The quota calculation module is determined according to the current quota pricing calculation method and specifications.(2)According to the demand analysis of the solar greenhouse cost management system.it is designed in detail.In the Visual Studio 2015 software.the C# language is used to program the solar greenhouse cost management system.The system is set as a UI interactive interface.which is involved in the solar greenhouse.The basic information and building materials are classified and selected.For the fixed pricing and table output module.the SQL database is used to store the fixed data about the greenhouse cost.and the calculation and pricing of the solar greenhouse are combined.Through the adjustment of the market price.the project volume and pricing list of the solar greenhouse is finally derived as well as List of other items.(3)Before the system officially runs.test the internal source code and interface operation of the solar greenhouse cost management system through a combination of black box testing and dynamic testing to ensure the normal operation of the system.Finally.an example is used to test the internal source code and interface operation of the solar greenhouse cost management system.The program is applied.The system can digitize the engineering cost process of the solar greenhouse.and use the n-order Bezier curve to solve the problem that the gable curve is difficult to calculate.making the final cost result clearer.The system is relatively open.and the output list is not limited to what is contained in the software,but can also be added and output according to the needs of the project.This system has a certain auxiliary effect on the construction cost of the solar greenhouse.
