[0063] The longitudinal movement mechanism drives the swing mechanism to longitudinally move from one end of the longitudinal movement track 4 to the other end of the longitudinal movement track 4. During the longitudinal movement, the three cameras 28 collect images of the upper side of the vehicle cable 62;

[0064] Afterwards, the swing mechanism drives the three cameras 28 to flip downward, and the longitudinal movement mechanism drives the swing mechanism to move longitudinally back to the original position again. During this process, the three cameras 28 collect images of the lower side of the automobile cable 62;

[0065] After the acquisition is completed, the swing mechanism returns to its original position, and the main controller stores the acquired image in the main memory;

[0066] Step 5: After the image acquisition is completed, the transport vehicle drives the automobile cable 62 to move to the unloading station to remove the automobile cable 62;

[0067] After receiving the signal from the main controller, the slave controller drives the mobile driving motor 47 to operate. When the card reader 43 reads the label card 44 at the unloading station, the slave controller drives the transport vehicle to stop moving.

[0068] Step 6: The transport vehicle that has completed unloading moves to the loading station again;

[0069] After receiving the signal from the main controller, the slave controller drives the mobile driving motor 47 to operate. When the card reader 43 reads the label card 44 at the loading station, the slave controller drives the transport vehicle to stop moving.

[0070] Step 7: Repeat steps 2 to 6.
