Abstract

The invention provides a health monitoring system for a concrete structure. The health monitoring system comprises a sensor subsystem, a data acquiring subsystem, a communication system and a monitoring center. The sensor subsystem comprises a piezoelectric intelligent aggregate sensor and other sensors, wherein the piezoelectric intelligent aggregate sensor is used for monitoring cracks of the concrete structure, a piezoelectric force sensor is used for acquiring impact load of the structure, and an acceleration sensor is used for obtaining structural vibration information. The data acquiring subsystem is mainly composed of a data acquisition card and ancillary facilities including a piezoelectric ceramic driving power supply, a charge amplifier and the like. A communication subsystem adopts a wired mode and is communicated with an upper computer in a mode that a transmission control protocol (TCP)/Internet protocol (IP) is built in Ethernet. The monitoring center mainly comprises a driving monitoring module, a driven monitoring module, an acceleration monitoring module and other software functional modules. The health monitoring system for the concrete structure is simple to operate, and strong in man-machine interaction, can be expanded according to actual requirements at a later stage, and is very suitable for health monitoring of the concrete structure in practical engineering.

Description

Technical field [0001] The invention relates to the technical field of civil engineering structure monitoring, in particular to a structural health monitoring system for concrete structures. Background technique [0002] At present, my country is in a period of large-scale infrastructure construction. As the most commonly used structural form, concrete structures are widely used in the construction of various engineering structures. During its long service process, aging and damage of materials inevitably occur, thereby reducing the reliability of the structure. Therefore, the problem of structural reliability has been widely concerned. Structural health monitoring, as a technology that can detect structural damage in time by obtaining relevant information about the structure, and then give users a safety warning, has been one of the research hotspots in the field of civil engineering in recent years. [0003] However, the traditional non-destructive testing methods of concrete st...
