汽车焊装车间自动化控制技术

Analysis of control system in body welding workshop

汽车焊装车间的控制系统采用"集中监控,分散控制"的模式,向分散化、网络化、智能化方向发展,使整个控制系统高效安全、简洁柔性以及成本更低。给出了焊装车间网络结构的系统组成。安全总线系统实现了将安全技术集成到标准控制系统中,使得安全集成控制器采用同一个总线使标准的I/O和安全故障I/O进行通信,保证了旧的总线系统和最新安全技术的有机结合。结构化和模块化编程使得焊装车间控制系统软件更易阅读和维护。

Based on the centralized monitoring and decentralized controlling mode,the control system in body welding workshop is developing in the direction of distribution,network and intelligence,which ensures the whole control system to run more efficient, safe ,flexible and with low cost.This paper shows the constitution of the network structure in body welding workshop.The safety bus system has integrated the security control into the standard control system ,with which the safety integrated controller makes the communication between standard I/O and fail-safe I/O with same bus,which ensures the organic combination of the existing bus system and the latest safetyrelevant technology.Furthermore ,the structured and modular programming makes software of control system easier be read and maintained.
