[0070] The control module is equipped with an analysis unit, which is used to analyze the images collected by the camera.

[0071] Example 2, this example is a further description of the above examples. It should be understood that this example includes all the foregoing technical features and is further described in detail:

[0072] In this embodiment, the connecting buckle mainly consists of a U-shaped buckle 6, a bolt 7, and a nut 8;

[0073] Further integration Figure 10 , Figure 11 As shown, the application method of the installation assistance system is characterized by:

[0074] S1. Placement and installation: Place and install the frame 1 on the cable 9;

[0075] S2, Positioning: The climbing module 2 drives the frame 1 to crawl along the cable-stayed bridge to the position of the corresponding mounting hole;

[0076] The frame crawling operation is as follows: the control drives the roller to rotate, and the roller rolls along the inclined cable to drive the frame forward. By setting rollers for driving, it is easy for the frame to move on the uneven inclined cable that is full of clamps and installation ropes.

[0077] The limiting unit can bring the frame that is off-center from the cable stay back to the center position. Specifically, the control adjustment unit then drives the third drive motor to start, so that the second mounting frame moves along the arc frame, thereby moving the frame to the center position of the cable stay. Then, the control module controls the clamping mechanism of the limiting unit to retract, so that the two clamping rods of the clamping mechanism retract and abut against the cable stay. Then, the third drive motor is driven to rotate in the opposite direction, so that the arc frame is reset.

[0078] When locating the mounting holes, a positioning module is used for visual assistance to locate the position of the mounting holes.

[0079] S3. Binding connection: The connecting traction module 3 extends through the hoisting mechanism 32 to lower the connector 31, and the operator binds the connecting buckle to the connector 31.

[0080] The installation method of the connecting buckle and connector 31 is as follows: First, insert the bolt head into the second placement groove 312 with the head facing inward and install it in place. Then, match and install the nut in the third placement groove 313. After hanging the U buckle with the point light source installation wire rope, place it in the first placement groove 311.

[0081] S4. Lifting and alignment: The hoisting mechanism 32 retracts and lifts the connector 31, thereby moving the connector 31 to the position corresponding to the mounting hole and aligning the connector 31 with the mounting hole.

[0082] By setting the orientation block 316 and the limiting plate, when the positioning block rises into the matching limiting hole, the orientation of the connector 31 is restricted to prevent the connector 31 from rotating, which would cause the bolt and the positioning hole to misalign.

[0083] S5. Installation: Lock the connector buckle onto the corresponding mounting hole using locking module 5.

[0084] The specific installation method of step S5 is as follows: align the bolt of connector 31 with the mounting hole, and then rotate and push the bolt through the locking module 5 to pass through the mounting hole and the U-shaped buckle and connect with the nut, thus completing the connection and installation of the mounting hole of the upper mounting frame of the point light source.

[0085] Then the device can be moved to the next mounting hole and steps S1-S5 can be repeated for installation until all mounting holes that need to be installed according to the project settings are installed.

[0086] After the upper mounting frame is installed, the operator can then connect and fix the lower connecting part of the point light source to the lower mounting frame and tighten the light strip.

[0087] The upper installation frame is generally composed of a crossbeam that is fixed to the cable-stayed cable by clamps and safety ropes. The crossbeam is provided with mounting holes for the steel wire rope and connecting buckle of the point light source to be suspended and fixed.

[0088] This system, through the climbing module 2, enables the device to climb stably along the cable-stayed bridge, while simultaneously adjusting the device's position and balance to ensure alignment with the cable-stayed bridge. The positioning module and positioning block allow the connector 31 to automatically align with the mounting hole. The locking module 5 automatically locks the connecting buckle. The limit mechanism 22 automatically corrects the device's deviation. Using this device for assisted installation reduces construction risks.
