Description
Technical field
The present invention relates to a kind of optical fiber coiling system, particularly relate to a kind of optical fiber automatic solid matter control system.
Background technology
Along with fiber optic communication and the development of Fibre Optical Sensor, in order to meet various application scenario, to the requirement of optical fiber coiling increasingly
High.The application such as many is met an urgent need, speedily carried out rescue work, field work, wire-guided weapon, it is desirable to optical fiber (includes optical cable), it is possible to fast rapid release
Put, Reusability.This just requires optical fiber cable group necessary solid matter in winding process, and otherwise last layer optical fiber will be pressed into next layer,
Cause line-outage contingency due to line ball during optical fiber release.Optical fiber close arrangement makes gap between same layer optical fiber the least, and upper strata optical fiber can not be embedding
Enter lower floor, thus stop optical fiber skip floor line ball, it is ensured that when meeting the performance requirements such as appropriate release tension force and speed during release, no
Occur that broken string, loss are significantly increased etc. to have a strong impact on the accident of communication quality and occur.
The core sensing element of many Fibre Optical Sensors is fiber optic coils (such as optical fibre gyro), and this coil is when coiling, it is necessary to protect
Demonstrate,prove certain symmetrical winding, as the winding of optical fibre gyro just has two symmetries the most symmetrical, quadrupole, the ends of the earth symmetrical.Symmetric coil requirement
Every layer of optical fiber is in winding process, it is necessary to have the least tension force, and the most necessary close-packed arrays, turn-to-turn can not have big gap the most not
Energy spacing is the least, and (as shown in Figure 6, a leftmost width figure is situation during the normal winding displacement of optical fiber, and middle second width is optical fiber row
Occurring the situation that spacing is excessive during line, rightmost the 3rd width is the situation that optical fiber winding displacement occurs that spacing is too small), interlayer can not staggered floor,
The most just destroy fiber optic coils symmetrical structure (as it is shown in fig. 7, Far Left the first width figure is the normal situation of optical fiber winding displacement,
Middle second width figure is the situation that optical fiber winding displacement angle of lag is excessive, and rightmost the 3rd width figure is the feelings that optical fiber winding displacement angle of lag is too small
Condition), technical requirement cannot be met and become waste product.Visible optical fiber is close-packed arrays under some tension, is in fiber optic applications
A very important technical specification.
Primarily now rely on the way of human assistance, when operator find cumulative error winding displacement to be affected, the most manually do
In advance, manually regulation creel stand position (by arranging key the soonest) or the manual winding displacement position that arranges of stopping eliminate error.This behaviour
Not only affecting work efficiency, frequent parking also can affect line bag quality and concordance, and the operation of heavy dependence operator
Technical ability and proficiency level, be unfavorable for large-scale production.
