光缆护套壁厚测量控制系统设计与实现

Design and Implementation of Sheath Wall Thickness Measurement Control System for Fiber Optic Cable

针对现有生产线不具有对光缆外护套的壁厚及偏心度进行检测和实时控制的能力,仅以外径控制来代替壁厚间接控制而导致的护套壁厚偏差较大且调整不及时的问题,展开了光缆护套壁厚测量控制系统的设计。该系统采用先进的超声检测技术,选用国外成熟的传感器产品,能够广泛适配新接入监测设备的通信接口,硬件的采集精度、采集周期、采样范围等指标能满足实际生产需要。该系统的软件功能模块可重用、可配置、可拆卸,采用图形化的显示方式,能够直观地显示壁厚监测数据、状态,并能够记录、存储整个生产过程数据,具有数据分析、数据导出等功能,有支持与其他系统数据互通的能力。该系统采用结构化的工装将4个超声波传感器安装在冷却水槽中。该系统能够满足对光缆外护套壁厚、偏心度的实时在线测量的实际需要,实现生产过程的优化和数字化改造,提高光缆产品的成品率。

The existing production line does not have the ability to detect and real-time control the wall thickness and eccentricity of the cable outer sheath,and only uses the outer diameter control to replace the indirect control of the wall thickness,which results in the large deviation of the sheath wall thickness and the untimely adjustment.The design of the sheath wall thickness measurement control system for optical cable is carried out.The system adopts advanced ultrasonic testing technology,selects foreign mature sensor products,and can widely adapt to the communication interface of new access monitoring equipment,and can meet the actual production needs from the hardware acquisition accuracy,acquisition cycle,sampling range and other index range.The software function modules of the system have reusable,configurable and detachable.The software function modules adopt graphical display mode,which can intuitively display the wall thickness monitoring data and status,can record and store the data of the whole production process,have data analysis function,data export function and so on,and have the ability of data interchange with other systems.The system uses structured tooling to install four ultrasonic sensors in the cooling water tank.The system can meet the actual needs of real-time on-line measurement of the wall thickness and eccentricity of the cable sheath,realize the optimization of the production process and digital transformation,and improve the yield of optical cable products.
