A health detection system for civil engineering structures

Abstract

The invention belongs to the field of civil engineering health monitoring, in particular to a civil engineering structure health detection system, comprising: a central processing unit, a building body detection unit, an environment detection unit, a camera device, a remote monitoring terminal and a solar power supply device; the central processing The device is wirelessly connected to the remote monitoring terminal through the wireless transceiver module one; the solar power supply device is electrically connected to the central processing unit. The invention can automatically collect vibration physical quantities, acceleration physical quantities, internal cracks and defect physical quantities, strain physical quantity signals, air pH values, temperature and humidity values, wind pressure values, wind speed values ​​and video signals including building detection points, and has related physical quantities Alarm function for abnormal signal. It overcomes the shortcomings of the existing civil engineering structure health status monitoring that requires a huge workload due to manual regular inspection records and data comparison, and can automatically send the monitoring data to the monitoring terminal at any time through the wireless network.

Description

technical field [0001] The invention belongs to the field of civil engineering health monitoring, and in particular relates to a civil engineering structure health detection system. Background technique [0002] The service life of major engineering structures is as long as decades or even hundreds of years. Under the joint action of environmental erosion, material aging, long-term effect of load, fatigue effect and other disaster factors, it will inevitably lead to damage accumulation and resistance attenuation of the structural system. , in extreme cases may lead to catastrophic accidents. With the increasing attention to the safety, durability and normal use of engineering structures, people hope to fully understand the health of the structure even after some catastrophic accidents such as earthquakes, typhoons, and explosions occur during the service period of the structure. condition to determine if, and when, repairs and maintenance to the structure are required.

Problems solved by technology

[0003] The existing health status monitoring of civil engineering structures requires a huge workload due to manual regular inspection records and data comparison. At the same time, it poses certain dangers to workers and cannot meet the growing demand for civil engineering.

Even if some monitoring systems adopt automatic monitoring methods, there will be problems such as complex wiring and low wiring efficiency, which will consume a lot of manpower, material resources, and financial resources; restricted by wiring restrictions, it is impossible to move and operate conveniently, which may easily cause data acquisition. take mistakes and other shortcomings
