VMIVME-6015
七十年代以前,控制系统中采用模拟量对传输及控制信号进行转换、传递,其精度差、受干扰信号影响大,因而整个控制系统的控制效果及系统稳定性都很差。七十年代末,随着大规模集成电路的出现,微处理器技术得到很大发展。微处理器功能强、体积小、可靠性高、通过适当的接口电路用于控制系统,控制效果得到提高;但是尽管如此,还是属于集中式控制系统。随着过程控制技术、自动化仪表技术和计算机网络技术的成熟和发展,控制领域又发生了一次技术变革。这次变革使传统的控制系统(如集散控制系统)无论在结构上还是在性能上都发生了巨大的飞跃,这次变革的基础就是现场总线技术的产生。
现场总线是连接现场智能设备和自动化控制设备的双向串行、数字式、多节点通信网络,它也被称为现场底层设备控制网络(INFRANET)。80年代以来,各种现场总线技术开始出现,人们要求对传统的模拟仪表和控制系统变革的呼声也越来越高,从而使现场总线成为一次世界性的技术变革浪潮。美国仪表协会(ISA)于1984年开始制订现场总线标准,在欧洲有德国的PROFIBUS和法国的FIP等,各种现场总线标准陆续形成。其中主要的有:基金会现场总线FF(Foundation Fieldbus)、控制局域网络CAN(Controller Area Network)、局部操作网络LonWorks(Local Operating Network)、过程现场总线PROFIBUS(Process Field Bus)和HART协议(Highway Addressable Remote Transducer)等。但是,总线标准的制定工作并非一帆风顺,由于行业与地域发展等历史原因,加上各公司和企业集团受自身利益的驱使,致使现场总线的国际化标准工作进展缓慢。但是不论如何,制定单一的开放国际现场总线标准是发展的必然。
