Design And Implementation Of Web-based Virtual Laboratory For Single Crystal Furnace

With the advance of the national new energy strategy and photovoltaic energy industry, photovoltaic application materials become the more important production means in this industry and the related equipment "single crystal furnace" also plays a more important part, which provides the basis and technical support for the whole photovoltaic application industry. Currently, because photovoltaic materials have the limited output and expensive price, it becomes one urgent need of the entire photovoltaic application industry chain, that the production equipment and manufacturing process of photovoltaic materials are improved in order to increase the purity and yield of photovoltaic materials. We upgrade the production equipment with the long-cycle and high-cost by the traditional method, so we shall explore and seek one new way of improving photovoltaic material production equipment, which is a hot topic of application research.In this thesis, we try to introduce the virtual experiment technology into the photovoltaic material production equipment industry and solve practical problems encountered in the design, production and service of this industry by virtualization software technology. Meanwhile, we are studying and developing virtual(industrial) laboratory for the photovoltaic material production equipment “single crystal furnace” with the method and process of software engineering and the industry background and work experience of the author so that to shorten design cycle, reduce development costs, increase production efficiency and improve service quality.In this thesis, the related research works are listed as follows:① the optimal solution is given for the design, production and service of single crystal furnace by analyzing questions and aggregating requirements; ② the virtual(industrial) laboratory, which consists of the equipment design platform, the manufacturing process simulation platform and the EaaS(Experiment/Equipment as a Server) platform, is designed and implemented according to the solution; ③ the overall framework and each function module are debugged and tested to propose comments and suggestions for improving the system.In this thesis, the related innovations are summarized as follows:① the virtual(industrial) laboratory for "single crystal furnace" is proposed firstly, which introduces the virtual experiment technology into the photovoltaic material production equipment industry; ② the comprehensive virtual laboratory solutions for the special industry is proposed firstly, which introduces the virtual experiment platform into each part of the special industry link(including production equipment design in the prior period, manufacturing process simulation in the middle period and product maintenance and problem tracking in the later period); ③ the prototype design of the EaaS is proposed firstly, which introduces the concept and model.of cloud computing into the virtual laboratory and will be achieved with the basic functions of virtual experiment platform and data sharing technology based on WEB.The above-mentioned research works and innovations give a valuable attempt for improving photovoltaic materials production equipment by the software engineering method and the virtual experiment technology. In the future, we will continue to promote the related application research work. In conclusion, the research achievement not only accelerates the upgrading of photovoltaic materials production equipment but also promotes the evolution and development of the virtual laboratory.
