Description

Technical Field

[0001] The present invention belongs to the technical field of foundation pit air film environment perception, and in particular relates to a foundation pit air film intelligent environment perception system. Background Art

[0002] Air-supported buildings use special building membrane materials as the outer shell, and steel cables are laid on the membrane surface, using the positive pressure of air (usually the pressure difference between the inside and outside is about 250Pa) to support the main body of the building. Due to its novel shape, low cost, short construction period, low energy consumption, and large span, it has been widely used in the industrial and civil construction markets. However, since air-supported buildings are supported by indoor gas, they are often affected by external factors such as wind and snow loads during operation. The building has large deformation and high deformation frequency. When the weather is abnormal, the internal and external pressure difference needs to be adjusted in time. In addition, the surface wind pressure, building dynamic characteristics, support internal force, and steel cable tension of air-supported buildings need to be effectively monitored during construction and operation to grasp the stress state of the building. Finally, real-time control and adjustment of relevant parameters of the membrane environment to provide a good environment for people living and working in the building is very necessary for the widespread application of air-supported buildings in the industrial and civil construction industries.

[0003] The prior art still has the following deficiencies:

[0004] The existing technology does not have a control system that integrates functions such as inflation and pressure maintenance, lighting control, cooling and heating control, indoor air quality monitoring, security monitoring, fire alarm, report query and remote access. At the same time, in the north, the snowfall is heavy and the snowfall period is long. The snow will gradually form blocks and accumulate, forming a large pressure on the top of the air-supported building. If the air-supported building needs to be used normally, the fan air volume needs to be increased to increase the supporting force of the air-supported building, which wastes energy. When the snow accumulates heavily, it may even crush the air-supported building. Summary of the invention
