Abstract

The invention relates to a temperature control method for an optical fiber preform acceleration mold holder, a computer medium and a computer, and the temperature control method for the optical fiber preform acceleration mold holder comprises the following steps: S1, monitoring and recording the temperature of the mold holder and the diameter of an optical fiber preform; s2, making a curve graph according to the temperature and diameter data of the die holder; s3, judging whether the current state is in a speed increasing stage or not; s4, according to the current temperature curve of the die holder, the curve slope is calculated, the temperature change trend is estimated, and the temperature change of the die holder is controlled through preset time; and S5, detecting and judging whether the diameter of the current optical fiber preform is in a preset range or not when the temperature of the die holder is changed to the required temperature after the preset time is up. According to the method for controlling the temperature of the speed-increasing die holder of the optical fiber preform, the temperature change trend is estimated according to the curve slope calculated according to the current curve graph, the temperature change of the die holder is controlled, the response time is shortened, and the temperature of the die holder is adjusted in time, so that the standard-reaching rate of the coating diameter of the optical fiber preform is increased.

Description

technical field [0001] The invention relates to the technical field of optical fiber preform production, in particular to a method for controlling the temperature of an optical fiber preform speed-up mold base, a computer medium and a computer. Background technique [0002] During the production process of the optical fiber preform, it needs to go through three stages of speed up, steady speed, and end of the rod. In these three stages, the temperature of the mold base needs to be monitored and adjusted respectively to ensure that the diameter of the optical fiber preform reaches the standard. [0003] In the prior art, the automatic adjustment of the mold base temperature through the mold temperature PID system is only applicable to the steady speed stage. For the case where the coating diameter changes too fast in the speed up stage, the existing mold temperature PID system automatically adjusts the temperature. The response time of the mold base water bath is too long, wh...
