Abstract

The invention relates to a pneumatic membrane building deformation monitoring system. The technical problem that an existing constant-pressure control strategy cannot effectively prevent a membrane top from collapsing under heavy snow load is mainly solved. According to the technical scheme, the pneumatic membrane building deformation monitoring system comprises a pneumatic membrane building composed of a gas membrane building retaining wall and a gas membrane body, and further comprises at least two displacement sensors for monitoring deformation of the pneumatic membrane building, a base, a stay wire, a plurality of annular lifting hooks, a membrane top fixing block and a pneumatic membrane building deformation monitoring device. The base is arranged on an inner wall of the gas membrane building retaining wall , the membrane top fixing block is arranged on the inner top face of the gas membrane body, the annular lifting hooks are evenly arranged on the inner top face of the gas membrane body and located between the membrane top fixing block and the bottom end of the inner top face of the gas membrane body, and the displacement sensors for monitoring deformation of the gas membrane building are installed on the base. One end of the stay wire is connected with the displacement sensors, and the other end of the stay wire penetrates through the annular lifting hooks to be connected with the membrane top fixing block.

Description

technical field [0001] The invention relates to a deformation monitoring system of an inflatable membrane building, which belongs to the technical field of monitoring. Background technique [0002] The inflatable membrane building industry generally adopts the method of controlling the internal pressure of the membrane to maintain the basic shape of the membrane building, supplemented by monitoring data of wind speed, wind direction, and snowfall thickness, and adopting appropriate algorithms to ensure the basic safety of the building. [0003] The inherent feedback, error, and adjustment links of the PID control logic adopted by the existing constant pressure control cannot monitor the deformation of the membrane. When encountering strong winds or snow accumulation, the increase in the pressure inside the membrane may even give a wrong adjustment direction, seriously If it is not, it will aggravate the collapse of the membrane and cause a safety accident. [0004] The trad...
