Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic air film cabins, and in particular to a photovoltaic air film cabin data real-time collection and monitoring system and method thereof. Background Art

[0002] The photovoltaic air film cabin is a new structure that combines air film technology and photovoltaic technology. It realizes solar power generation by installing photovoltaic modules on the top or wall of the air film cabin. The air film cabin is a spatial structural system supported by internal micro-positive pressure, and no beams or columns are required to support it. The photovoltaic air film integration technology integrates flexible photovoltaic modules with the air film structure to form a new model that can generate energy for its own use. The photovoltaic air film cabin uses lightweight flexible materials and has a light weight. The weight of each square meter of membrane material plus external steel cables is only about 1.5 kilograms. It can adapt to soft soil foundations and other complex geological conditions, and does not require complex foundation treatment, which reduces the cost and cycle of infrastructure construction. The foundation of the air film cabin is highly adaptable and can be used in areas with poor geological conditions, such as soft soil foundation. Only simple foundation treatment is needed to meet the use requirements. The air film cabin relies on the internal and external air pressure difference as support. It does not require load-bearing structures or bending, torsion and compression components. The forces acting on the foundation are mainly upward pull and horizontal forces. The internal pressure can also be adjusted dynamically in real time according to different weather conditions. The photovoltaic air film cabin integrates lightweight and flexible photovoltaic components, high-performance energy storage systems, and energy microgrid systems formed by generator sets to achieve a new mode of "spontaneous use and energy self-sustaining" of the air film, effectively solving the air film operation's dependence on traditional power supply energy.

[0003] Through the construction and installation technology of the air-supported membrane photovoltaic system using special flexible component frames and fasteners, the problems of coordinated deformation and load-bearing of the air-supported membrane structure and photovoltaic components are solved, ensuring safe operation in severe weather. The photovoltaic air-supported membrane cabin is equipped with an information system for real-time monitoring of energy and safety through a remote terminal, realizing the intelligent management of energy efficiency and safety of the photovoltaic air-supported membrane structure. The structural characteristics of the air-supported membrane cabin have good thermal insulation properties, which can reduce energy consumption. At the same time, the integrated photovoltaic components can generate clean energy and help with low-carbon emission reduction. The air-supported membrane cabin can be quickly installed and disassembled, is portable and reusable, has a short construction period, and can greatly save time and economic costs.

[0004] Real-time data collection is carried out on the equipment of the photovoltaic air film cabin, such as photovoltaic modules, inverters, weather stations, power terminal equipment, etc., including parameters such as power generation, voltage, current, temperature, as well as meteorological information such as sunshine, temperature, wind speed and direction.
