IPC向低成本和可靠性方向发展
在传统的过程控制系统中,现场设备层基本被PLC 所垄断,过程控制层和生产管理层控制设备主要是由各种IPC 或小型机组成。
20世纪90年代以来,由于PC-based 工业计算机的发展,特别是IPC的CPU运行速度越来越快、储存容量增大、成本降低、可靠性提高以及IPC进一步开放,使IPC 成为实现工业自动化的主要控制装置,其应用的领域越来越广。IPC 的应用除了传统的过程控制(冶金、石化、电力) 和制造自动化外,还应用于机电一体化产品,如机床、轻机、纺机和印机等以及电力监控、环保和楼宇控制等。世界电气公司都有自己的IPC产品,如Siemens的SIMA TIC PC 代表了IPC的水平,施耐德的热备系统Premium工控机等。目前国内IPC制造商主要有研华、研祥、华北、威达、大众等。几年前,当“软PLC”出现时,大部分人都认为IPC 可能会取代PLC,然而,到目前为止IPC不可能完全取代PLC。可以预见,目前IPC在现场设备层是不可能与的PLC竞争。
2.3 DCS 向管控一体化方向发展
DCS问世于1975年。生产厂家主要集中在国外ABB、Honeywell、Invensys、Emerson、Siemens 和三菱等公司。主要制造商已将DCS 形成功能、配置灵活的系列产品。
分析各制造商其系统结构和功能可以归纳以下5个特点:① 硬件积木化;② 软件模块化;③控制组态化;④通信网络化;⑤高可靠性。
目前小型DCS 发展也非常快,以便与PLC、IPC 和FCS 竞争,同时不少制造商又推出了PLC 与DCS 的混合系统HCS以实现多样化。近期ABB公司推出的AC 800 系统, Honeywell公司推出的Experion PKS(过程知识系统)、Emerson 公司的PlantWeb(Process Management),使生产过程的现场数据可有序无缝流通,实现企业信息管理与控制技术的无缝连接,使企业的盈利能力和生产效率得以提高,因此,DCS 不仅向仪表成套和控制系统(I&C) 方向发展,还将向管控一体化方向发展。
