| 中文摘要: |
| 介绍工程机械轮胎胎面挤出生产线PLC控制系统由S5系列升级为S7系列。改造重点：主机控制系统采用西门子S7-400 PLC，CPU采用CPU 414-2DP；人机界面采用研华工控机，重新制作操作台；单条称和连续称采用梅特勒-托利多称显示器；红外温度传感器测量出胶温度：裁切系统采用直流驱动器加直流电机控制裁刀输送带，编码器模块控制挤出胎面定长。改造后的生产线控制系统具有故障诊断、记录、查询和工艺参数记录等功能，生产线工艺质量和产量提高，故障率和维修成本降低。 |
| 英文摘要: |
| In this study，the PLC control system for OTR tire tread extrusion line was upgraded from S5 series to S7 series.In the upgraded system，Siemens S7-400 PLC was selected for the host control system with CPU 414-2DP.Advantech IPC was used as the man-machine interface and the whole operation platform was re-designed.Mettler-Toledo display was selected for balances.The temperature of discharged compound was measured using infrared temperature sensors.DC drive and DC motor were used in the cutting system.The length of extruded tread was controlled by encoder module.After the upgrading，the control system provided full functions such as fault diagnosis，recording and query，and process parameter recording.The product quality and production yield were improved，and the failure rate and maintenance cost were reduced. |
