Abstract

The invention relates to a structure intensity testing system based on an intelligent wireless sensor network, which comprises a monitoring terminal, an intensity testing sensor array arranged in a structure to be tested, a wireless sensor terminal node, a wireless routing node and a wireless base station node, wherein, the wireless sensor terminal node collects structure response output of the intensity testing sensor array under each loading grade, and transmits the structure response output by the wireless sensor network through the wireless routing node and the wireless base station node in sequence to the monitoring terminal. The invention also relates to a method for the system to carry out communication, data collection and visualization. The system and method of the invention overcomes the problems that the existing structure intensity testing systems have complex leads, big added weight, low intellectualization and networking degree, etc., can effectively reduce the number of the leads in a static force / fatigue testing system, improve testing precision and realize real-time and simultaneous collection, transmission, display and storage of the structural test data, and has the advantages of intellectualization, high efficiency and low cost.

Description

1. Technical field

[0001] The invention relates to a structural strength testing system, in particular to a structural strength multi-point testing system based on intelligent wireless sensor network technology, and at the same time relates to a method for visualizing the system. 2. Background technology

[0002] Structural strength test is an important means to study the strength of engineering structures. The static / fatigue test of the structure is to observe the performance of the structure under load in a planned way and analyze the measured parameters such as pressure, displacement, amplitude, vibration frequency, fatigue life, etc., to make a conclusion on the working performance and bearing capacity of the structure. Correct evaluation and estimation, and provide a reliable basis for verifying and developing computational theory of structures. Taking aircraft structure as an example, fatigue, corrosion and wear of fuselage structure are the three main modes that caus...
