自动化是一门涉及学科较多、应用广泛的综合性科学技术。作为一个系统工程,它由5个单元组成:
过程自动化:石油炼制和化工等工业中流体或粉体的化学处理自动化。一般采用由检测仪表、调节器和计算机等组成的过程控制系统,对加热炉、精馏塔等设备或整个工厂进行优控制。采用的主要控制方式有反馈控制、前馈控制和优控制等。
图4.自动化设备机械制造自动化:这是机械化、电气化与自动控制相结合的结果,处理的对象是离散工件。早期的机械制造自动化是采用机械或电气部件的单机自动化或是简单的自动生产线。20世纪60年代以后,由于电子计算机的应用,出现了数控机床、加工中心、机器人、计算机辅助设计、计算机辅助制造、自动化仓库等。研制出适应多品种、小批量生产型式的柔性制造系统(FMS)。以柔性制造系统为基础的自动化车间,加上信息管理、生产管理自动化,出现了采用计算机集成制造系统(CIMS)的工厂自动化。
管理自动化:工厂或事业单位的人、财、物、生产、办公等业务管理自动化,是以信息处理为核心的综合性技术,涉及电子计算机、通信系统与控制等学科。一般采用由多台具有高速处理大量信息能力的计算机和各种终端组成的局部网络。现代已在管理信息系统的基础上研制出决策支持系统(DSS),为高层管理人员决策提供备选的方案。
对社会的影响自动化是新的技术革命的一个重要方面。自动化技术的研究、应用和推广,对人类的生产、生活等方式将产生深远影响。生产过程自动化和办公室自动化可*地提高社会生产率和工作效率,节约能源和原材料消耗,保证产品质量,改善劳动条件,改进生产工艺和管理体制,加速社会的产业结构的变革和社会信息化的进程。
