Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, be a kind of theory diagram of steel structure net rack monitoring system of the utility model, including accelerometer 2,
Hydrostatic level 4, surface strain meter 6, camera, processor and PC；The accelerometer 2 is connected with the processor, institute
State the micro-vibration that accelerometer 2 monitors steel construction；The hydrostatic level 4 is connected with the processor, the hydrostatic level 4
Monitor the amount of deflection of steel construction（Vertical deformation）；The surface strain meter 6 is connected with the processor, and the surface strain meter 6 is supervised
Survey the internal force of steel structural rod piece；The camera is connected with the processor, and the camera monitors the corrosion of steel structural rod piece
Situation；The PC is connected with the processor, and the data that the PC receives the processor are analyzed again, and to analysis
Result is shown.
Work brief acceleration meter 2, hydrostatic level 4, surface strain meter 6, camera shake to the micro- of steel structure net rack 1 respectively
Dynamic, amount of deflection（Vertical deformation）, rod member internal force, the parameter such as rod member corrosion condition carry out data acquisition, by the data transfer after collection
Processed to processor, data after treatment are passed in PC, PC is provided with specific DAS, soft
Part carries out comprehensive analysis processing to data, judges the health condition of steel structure net rack 1, finally judges that structure is shown by PC
Show.
As shown in Figures 2 and 3, respectively steel structure net rack schematic diagram and the mounting arrangements schematic diagram of accelerometer 2, rack 1
Temperature joint, aseismatic joint, subsiding crack rack 1 is divided into different regions, each region is monitored according to single individuality.
The arrangement row accelerometer 2 of 3 row 3 in individual region, often place's arrangement X, Y, Z three-dimensional accelerometer 2, arranges 3 × 3 × 3=27 altogether
Individual accelerometer 2.For there is concavo-convex labyrinth suitably to encrypt arrangement accelerometer 2.
Accelerometer 2 is capable of the micro-vibration of measuring structure, by the vibration shape of the anti-selection structure of the test result of accelerometer 2.
The related data of the vibration shape after structural damage（The vibration shape, cycle etc.）Change occurs, therefore is understood by the test result of accelerometer 2
Structure relevant parameter, so as to the degree of impairment of decision structure.
As shown in figure 4, being the mounting arrangements schematic diagram of hydrostatic level 4, the position of installation needs to consider that vertical displacement will
Ask, and the simple requirement answered of easy for installation, later maintenance, while must assure that hydrostatic level 4 on corresponding baseline 5.It is quiet
