Specifically, it includes two cross beams 1 that are spaced apart front and back and extend in the left-right direction. Above the cross beams 1, there are multiple double-T plates 2 that are spaced apart left and right and extend in the front-back direction. The multiple double-T plates 2 are placed on the two cross beams 1, and then the strain sensor 5 and the crack width sensor 6 are installed at suitable positions on the double-T plates 2. The double-T plates 2 are provided with a strain sensor 5 (the strain sensor 5 is mainly used to measure the strain generated by the deformation of an object under force) and a crack width sensor 6 (the crack width sensor 6 is mainly used to automatically measure and monitor the crack width value on the surface of the structure in real time, especially during the cracking process of the crack).

[0048] When the strain sensors 5 and the crack width sensors 6 detect that the double-T plate 2 has fractures or deformations, they can transmit the information to the controller 16. The controller 16 then sends an alarm to the display screen 9. When the display screen 9 shows that there is a problem with the double-T plate 2, the user can drive the camera 7 to move under the action of the first driving mechanism 3 and the second driving mechanism 8, so as to observe the double-T plate 2 for the next operation.

[0049] Drive the first driving device to start, so that the output shaft of the first driving device drives one of the sprockets 301 to rotate. Since the sprocket 301 meshes with the chain 302, the chain 302 can be driven to move. During the movement of the chain 302, the connecting block 10 can be driven to move, and when the connecting block 10 moves, the moving plate 4 can be driven to move.
