Problems solved by technology

Since people cannot know the working conditions of the grid structure under the action of strong wind, the three main failure modes of the grid structure: "rod compression buckling, rod weld cracking and ball joint damage" are not easy to be found in time
This will cause the decline of the structure's wind resistance and bring great hidden dangers to the safety of the structure.

Embodiment Construction

[0018] Further illustrate the present invention below in conjunction with accompanying drawing.

[0019] this invention( figure 1 ) consists of a sensor system, an acquisition communication transmission interface, a structural health intelligent monitoring and diagnosis system, and a database. Among them, the output of the sensor system is connected to the acquisition communication transmission interface, and the output of the acquisition communication transmission interface is connected to the database. The automatic diagnosis system for joint weld crack damage is connected with the real-time evaluation system for anti-collapse safety of the damaged grid structure, and the output signal of the database is connected with the human-computer interaction interface.

[0020] The intelligent alarm system of the working state of the grid structure (Figure 2):

[0021] Since the large and complex roof grid structure has tens of thousands of rods, and the wind pressure has completel...

Abstract

This invention relates to an intelligent and healthy monitoring system for large complex roof web structure, which comprises sensor system, collection communication interface and data base for storing data and is characterized by the following: there are located with intelligent alarming system of the web structure working status and intelligent system to support steel racket work status and web structure pole and ball joint self diagnose system for welding crack and web structure anti-elapse safe real time valuation system between the communication interface and the data base to store data. This invention can realize the real-time automatic working status alarming , structure damage self-diagnose and structure anti-elapse safe valuation to ensure the safety in the use of the web structure.

Description

technical field [0001] The invention belongs to the field of structural engineering, in particular to an intelligent health monitoring system for large and complex roof grid structures. Background technique [0002] Because the large and complex roof grid structure (such as the roof structure of large stadiums and entertainment venues) can enable us to obtain more space for use, and can have a variety of beautiful shapes, it has developed rapidly in my country and around the world. , which has become the most widely used structure type in space structure. It is connected by a large number of rods in the space formed by two planes or curved surfaces to form the upper chord face and the lower chord face, and the webs and vertical rods are connected between them. Generally, it is welded with circular steel pipes and hollow steel ball nodes to form an integral structure. As the span of the structure increases, the complexity of the large and complex ro...
