A health monitoring system for metal roof panels

Abstract

The invention discloses a health monitoring system of a metal roof board. The system comprises a monitoring module, a wireless sensing network and a host computer; the monitoring module monitors the health status of the metal roof board; the wireless sensing network receives the health status of the metal roof board and sends the health status of the metal roof board to the host computer; and the host computer comprises a flexibility reconstruction module, the flexibility reconstruction module obtains a flexibility distribution condition of the whole metal roof board by reconstruction according to local flexibility change, obtained by the monitoring module, of the metal roof board, whether bolts on the metal roof board are loosened is determined, and alarm is raised if loosening is serious. The system can detect the deformation status of the whole metal roof board under the effect of natural loads including wind, rain and snow in real time, and reference indexes are provided for health management and maintenance of the metal roof board.

Description

technical field [0001] The invention belongs to the technical field of metal roof panels, in particular to a health monitoring system for metal roof panels. Background technique [0002] Metal roof panels have the advantages of light weight, high strength, and flexible design, and are widely used in the maintenance systems of large public buildings such as stations, warehouses, terminal buildings, and production plants. However, due to the complex natural environment of this type of building, the erosion of wind, rain, and snow all year round, accompanied by the alternating load of pulsating wind and sudden changes in cold and heat, will cause roof structure deformation, material fatigue damage, and bolt loosening And other problems, the resistance of the metal roof system is attenuated, and when the weather load does not exceed the design value, it will also cause damage to the roof, resulting in economic losses and even casualties. [0003] The health monitoring and evalu...
