西门子300PLC及上位机控制系统在电线生产线的应用

Application of S7-300 PLC and Computer Station Control System in Production Line of Wires

以西门子SIMATIC S7-300PLC与上位机相结合,综合控制电线外绝缘层生产,可实施性高,操作方便。从电线生产线各部分功能和生产流程入手,详细描述了在运动控制和温度控制相结合的硬件配置和控制程序,以及上位机监控实时软件方案。生产线的核心部分挤塑机按照4个状态跳转,运动控制系统以给定牵引机速度为准根据挤塑机状态调节运行,上位机采集现场数据实现监控。整个方案提高了控制系统的可靠性以及适应性,便于系统性能的提升,实时运行效果良好。

Introduces the application of industrial control system which is based on SIEMENS S7- 300 PLC and computer station in production line of wires. It start with the function of every parts and production process, then describe the software program of computer station and hardware configuration of movement and temperature control system. The main part of the production line is extruder which transform in 4 statements. The movement control system change the movement to adapt extmder＇s statements base on the set traction motor＇s speed. And the computer station collect and deal with the field dates of every functions, It can rise the reliability and adaptability of the control system effectively. The system works well in practice.
