Optical fiber preform rod tail wire drawing control system and method

Abstract

The invention discloses an optical fiber preform rod tail wire drawing control system and an optical fiber preform rod tail wire drawing control method. The system comprises a visual operation interface, a control module used for controlling an execution module to carry out wire drawing according to control parameters, a data processing module used for adjusting the control parameters and the execution module capable of carrying out wire drawing; the visual operation interface, the control module, the data processing module and the execution module are in communication connection in sequence,and a data acquisition module capable of acquiring optical fiber specification parameters and production line states in real time is in communication connection between the execution module and the control module. The method comprises the steps that firstly, the control parameters of different stages are set, and the specification parameters obtained after wire drawing are monitored; after an optical fiber preform enters a rod tail, the optical fiber preform is subdivided into n stages, the control parameters of each stage are independently set, and the control parameters are finely adjusted by taking specific time as an interval, so that the specification parameters are kept constant until the optical fiber preform is completely drawn. According to the device, the automatic procedure of rod tail wire drawing is greatly improved, the manual participation degree is reduced, the product consistency is ensured, the cost is low, and the efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of intelligent control systems and methods, in particular to a control system and method for rod tail drawing of an optical fiber preform. Background technique [0002] In the existing optical fiber preform drawing process, due to the large diameter difference of the optical fiber preform, in order to ensure the qualified rate of the product, employees need to waste a lot of time on the uninterrupted adjustment of the drawing process. In order to ensure the stability of the cut-off wavelength, drawing speed and tension when the rod is drawn to the end of the rod, it is necessary to manually intervene the value of the rod feeding speed and furnace power frequently. [0003] These frequent manual intervention actions occupy most of the production staff's time watching the line. If the line watching staff changes during the line watching period, or needs to assist the production with other tasks such as...

[0002] In the existing optical fiber preform drawing process, due to the large diameter difference of the optical fiber preform, in order to ensure the qualified rate of the product, employees need to waste a lot of time on the uninterrupted adjustment of the drawing process. In order to ensure the stability of the cut-off wavelength, drawing speed and tension when the rod is drawn to the end of the rod, it is necessary to manually intervene the value of the rod feeding speed and furnace power frequently

[0003] These frequent manual intervention actions occupy most of the production staff's time watching the line. If the line watching staff changes during the line watching period, or needs to assist the production with other tasks such as hanging rods and changing paint, it will be very difficult during the monitoring blank period. Potential for out of specification production parameters, especially at the end of the club

This will reduce the consistency of the product, directly affect the pass rate of the product, increase the production cost in a disguised form, and increase the line-seeing pressure of the production line personnel
