基于DeviceNet汽车涂装线控制系统设计

Based on DeviceNet automobile painting line control system design

本文阐述了DeviceNet和As-i现场总线的概念、特点,并根据上海汇众汽车有限公司油漆车间项目采取"分散控制、集中管理、各生产线集中控制"的方案要求,对其电泳烘干生产线电气控制硬件部分作了完整设计。此控制系统采用了基于DeviceNet的现场总线形式,以PLC作为核心元件,通过程序实现该生产线的自动启动、运行、停止、故障指示等功能要求,中央控制室实现对生产线的全面监控与管理。此控制方案经济适用、先进合理、安全可靠,管理和调试方便。

This article elaborated DeviceNet and the As-i field bus concept, the characteristic, and collect the numerous automobiles limited company paint shop project adopts ＂the disperser control, the centralized management, various production lines common control＂ the plan request according to Shanghai, ED ＆ oven production line electricity control hardware to its electricity partially to make the integrity design. This control system has used based on the DeviceNet field bus form, to PLC took the core part, realizes this production line automatic start, the movement through the procedure, stops, function request and so on failure indication, the center control room realization to the production line comprehensive monitoring and the management. This control plan economy is suitable advanced,reasonable, safe reliable, the management and the debugging is convenient.
