[0037] (4) Use simulated impact equipment to perform performance tests on the inner layer anti-collision structure and the outer layer dynamic anti-collision system to evaluate their energy absorption effect and structural stability under different impact conditions.

[0038] (5) Test the kinetic energy conversion efficiency of water to ensure that the buffer can rotate under the drive of water flow and effectively convert the kinetic energy of water into electrical energy.

[0039] (6) Connect to the remote control center and perform functional tests on the remote monitoring module to ensure that the status information of the early warning system, energy management system, and anti-collision system can be received and displayed in real time, and that abnormal conditions can be fed back and handled in a timely manner.

[0040] Step 4: Maintenance and optimization:
