Automatic space structure health monitoring system based on curved-surface wall-climbing robot sensor

Abstract

The invention discloses an automatic space structure health monitoring system based on a curved-surface wall-climbing robot sensor. The automatic space structure health monitoring system comprises a wireless sensor subsystem, a data acquisition subsystem, a data management subsystem and an automatic analysis terminal subsystem, wherein the wireless sensor subsystem consists of the wall-climbing robot with a wireless acceleration sensor, the acceleration data is synchronously acquired in different blocks, and the data is transmitted to the data acquisition subsystem; the data acquisition subsystem transmits the data to the data management subsystem so as to primarily process the data, and then the data is transmitted to the automatic analysis terminal subsystem, so that the automatic analysis for the structural modality and the early warning can be carried out. By adopting the automatic space structure health monitoring system, the wireless monitoring in the whole process can be realized, the wire distribution difficulty of the sensor can be avoided, the quantity of the sensor can be reduced by utilizing the movable sensor, and the monitoring cost is reduced; by utilizing the automatic mode recognition system, the manpower and the time can be saved, and the application requirement of projects such as wireless health detection of a large-span space structure can be met.

Description

technical field [0001] The invention belongs to the field of structural health monitoring, and in particular relates to a health monitoring system based on a robot wireless sensor that can move freely on a curved surface and can automatically analyze data in the whole process. Background technique [0002] As a public place where people gather, the safe service of large-span spatial structures such as stadiums, railway stations, and terminal buildings has attracted the attention of all walks of life. However, accidents of large-span spatial structures failing and collapsing under the action of long-term damage accumulation and complex loads are not uncommon. However, due to the lack of more economical and effective technical means, a large number of active spatial structures have not yet taken reliable safety measures for service. The consequence is that the potentially unhealthy spatial structure serves the public's social life, thus directly exposing people's life safety a...

Problems solved by technology

However, due to the characteristics of large space, multiple rods, and multiple nodes, the establishment of a wired sensor vibration monitoring system in a large-span grid structure requires more sensor nodes and laying long-distance cable transmission lines, and its layout and maintenance will cost a lot of time. Human and material resources; on the other hand, due to the large amount of data in the long-span spatial structure, the traditional modal recognition technology requires a lot of human interference and control by experts.
