监视控制和数据采集(SCADA)是一个硬件和软件系统,它被用于远程监视和过程控制.监控诸如管线、水和污水厂、灌溉渠、电力传送网和油田等设施.应用中,操作者可能身处离被监控点几公里或几百公里以外的地方,SCADA能使之成为可能.早期的SCADA是复杂的,按顾客要求定制,非常昂贵,只有大型企业才用得起.但是,现代的SCADA系统可以用低价、标准的零部件组装起来,顾客定制的软件和庞大的工程不再有必要了,现在对所有企业来说,SCADA已经成为价格低廉、性能可靠的监控系统.
Supervisory Control and Data Acquisition (SCADA) is a hardware and software system that is used for remote monitoring and process control, monitoring facilities such as pipelines, water and wastewater plants, irrigation canals, power transmission networks and oil fields. In applications where the operator may SCADA makes it possible to be within a few kilometers or a few hundred kilometers of the site being monitored. Early SCADA was complex and customized to customer requirements and expensive to use for large enterprises. However, modern SCADA systems can be assembled with low-cost, standard components, custom-made software and bulky engineering no longer necessary, SCADA has now become an inexpensive, reliable monitoring system for all businesses.
