Problems solved by technology

In the traditional wire drawing method, the operator directly sets the coating pressure of the corresponding speed range through the wire drawing experience. This method can meet the production requirements in low-speed wire drawing production, but when the wire drawing speed exceeds 1800m / min and high-speed wire drawing, the fiber coating diameter The adjustment is not smooth enough to meet production requirements

Abstract

The invention discloses an automatic control system and a control method for a coating diameter of an optical fiber, and relates to the automatic control system and the control method for the coating diameter in an optical fiber production process. The automatic control system comprises an optical fiber coating device, a coating device temperature sensor, a coating pressure sensor, a coating pipeline temperature sensor, a coating pressing device, a water bath device of the coating device, a coating curing device, a diameter measurement instrument for the coating diameter, a traction device, a winding device, a programmable logical controller and an upper host. The coating diameter of the optical fiber is measured by the diameter measurement instrument; the acquired coating diameter data of the optical fiber is transmitted to a drawing production control system through the diameter measurement instrument; the acquired coating diameter is analyzed and is compared with a set coating diameter by the drawing production control system; a coating pressure, a coating temperature and a coating pipeline temperature are adjusted automatically through a PID (proportion integration differentiation) algorithm, so that the coating diameter of the optical fiber is stabilized in a standard range.

Description

technical field [0001] The invention relates to an automatic control system and a control method for the coating diameter of an optical fiber, relating to an automatic control system and a control method for the coating diameter in the optical fiber production process. Background technique [0002] Coating diameter is an extremely important drawing control parameter of optical fiber. In the traditional wire drawing method, the operator directly sets the coating pressure of the corresponding speed range through the wire drawing experience. This method can meet the production requirements in low-speed wire drawing production, but when the wire drawing speed exceeds 1800m / min and high-speed wire drawing, the fiber coating diameter The adjustment is not smooth enough to meet production requirements. Contents of the invention [0003] The object of the present invention is to provide an automatic control system and control method for the diameter of the optical fiber coating i...
