A fatigue life management system and application of structural components based on the Internet of Things

Abstract

The invention discloses a fatigue life management system and application of structural components based on the Internet of Things. Based on the means of the Internet of Things, the three-dimensional two-dimensional code corresponding to the structural component delivery information database is printed on the structural components, so that the basic information of the tower crane components is not subject to time-space query; Stress and strain sensors are embedded in the structural components to sense the current fatigue damage in real time, and the real-time remaining life of the structural components is obtained by subtracting the fatigue damage life from the current life of the database. When the remaining life is insufficient, real-time warnings are made to prevent accidents, and the data is sent to the server database at the same time. Realize full-time management and control of structural component life, and prevent structural component safety accidents. It solves the problem of high incidence of construction accidents in recent years caused by the insufficient fatigue life of the current structural components.

Description

technical field [0001] The patent of the present invention relates to the field of building Internet of Things equipment, and specifically relates to a fatigue life management system and application of structural components based on the Internet of Things. Background technique [0002] Tower crane is a kind of vertical transportation mechanical equipment widely used in building construction to lift equipment and materials, which plays an important role in reducing energy and increasing efficiency and improving project quality; according to the statistics of China Construction Machinery and Equipment Yearbook in 2018, as of 2018, China The number of tower cranes is about 400,000-450,000, and will be further expanded with the promotion of construction industrialization; and with the widespread use of tower cranes, safety accidents continue to occur, and it is of great practical significance to improve the level of tower crane safety management technology. [0003] Tower crane ...

AI Technical Summary

Problems solved by technology

[0004] In the current management of tower crane equipment, manual inspection is mainly relied on to eliminate the safety risks caused by the appearance damage of tower crane structural parts. However, due to the defects of current manual means, it is almost impossible to grasp the remaining fatigue life of relatively reliable tower crane structural parts. Therefore, Usually, in the disposal of equipment scrapping, decisions can only be made by relying on the inspection conclusions of relevant agencies after the specified service life; The actual service life before the treatment is generally about 10 years, which means that during the entire service period of the tower crane structural parts, there will be many handovers between different projects, and the poor preservation of procedures, use records and maintenance records will also cause problems for the tower crane. The scrapping treatment of components has brought certain difficulties

[0005] In short, the current safety management of tower crane components mainly relies on manual inspection, which has defects such as insufficient control, inconvenient management, and insufficient informatization. In particular, the fatigue life of tower crane components cannot be reliably grasped. Important causes of major security risks in components
