step 2, starting automatic fiber coiling, wherein a motor in a power module drives a rotary disc and an optical cable conveyor belt to start working, and an optical cable fixer drives an optical fiber to be coiled on the optical cable conveyor belt along with the rotation of the optical cable conveyor belt;
step 3, pressure rods below the rotating discs acquire pressure data of corresponding positions in real time through pressure sensors, pressure values of optical fiber coils on each rotating disc are obtained, and the pressure values are sent to a control module;
step 4, setting a threshold value of the tolerance pressure of the optical fiber according to the type and the parameter of the optical fiber, and dynamically monitoring the pressure value of each place in the fiber coiling process through a dynamic adjustment algorithm; if the pressure value at a certain place exceeds the threshold value, the control module contracts the length of the corresponding pressure rod through the power module, so that the pressure value of the optical fiber coil at the position is reduced;
step 5, if the pressure value of the optical fiber coil is reduced below a threshold value after the pressure rod is adjusted, continuing to coil the optical fiber; if the pressure value of the optical fiber coil still exceeds the threshold value after the pressure rod is adjusted, an alarm is sent out, and meanwhile, the control module controls the rotating disc to stop working;
step 6, manual intervention is performed to check whether the optical fiber is broken or not, and winding and knotting are performed; if the optical fiber is broken, the optical fiber is taken down, and the step 1 is returned to for re-coiling; if the optical fiber is wound and knotted, the winding and knotting position of the optical fiber is untied, and then the fiber coiling is continuously started until the fiber coiling is completed.
10.
