Optical fiber production temperature automatic control system and control method thereof

Abstract

The invention discloses an optical fiber production temperature automatic control system and a control method thereof and particularly relates to the technical field of optical fiber production temperature control. The optical fiber production temperature automatic control system comprises a PID control module, the connecting end of the PID control module is connected with a temperature detectionmodule, the connecting end of the temperature detection module is connected with a temperature display module and an alarming module, the PID control module is used for measuring and comparing detected temperature data and correcting mistakes in the system, and the temperature detection module is used for detecting the temperature change situation of optical fibers in the production process. The temperature data change in a furnace cavity is collected in real time through a double-laser infrared thermometer connected to the connecting end of a color ratio temperature measuring unit, the changeof an input value and the change of an output value in the temperature data collecting process are judged through a function equation met by a proportional unit, an integral unit and a differential unit on the PID control module, and the temperature is self-regulated through the PID control module.

Description

technical field [0001] The invention relates to the technical field of optical fiber production temperature control, more specifically, the invention relates to an automatic control system and control method for optical fiber production temperature. Background technique [0002] Optical fiber is the abbreviation of optical fiber, which is a kind of fiber made of glass or plastic, which can be used as a light transmission tool. [0003] The invention patent of patent application publication number CN 104445917 A discloses an automatic control system and control method for the temperature of optical fiber production, including a drawing furnace and a temperature testing device. The temperature testing device is installed in the drawing furnace and used to detect the Temperature; a temperature transmitter, which is installed and connected to the output terminal of the temperature testing device, and used to transmit temperature signals; a controller, which is used to receive th...

Problems solved by technology

[0004] However, in actual use, there are still many shortcomings. For example, technicians can adjust the temperature through the change of wire diameter and wire drawing speed fed back by the caliper, but in the process of temperature adjustment, technicians cannot accurately judge whether the temperature is Deviation from normal values, resulting in uneven production quality of optical fiber
