SCADA systems are highly distributed systems that are often used to control geographically dispersed assets,spread over thousands of square kilometers,where centralized data acquisition and control are critical to system operation.They are used in water distribution systems such as water distribution and wastewater collection systems,oil and gas pipelines,power grids and rail transportation systems.

A SCADA control center centrally monitors the communication network on the site for a long time,including monitoring alarms and processing status data.Based on the information received from the remote station,automated or operator-driven monitoring commands can be pushed to the remote station control device,commonly referred to as a field device.Field devices control local operations such as opening and closing valves and circuit breakers,collect data from sensor systems,and monitor the local environment for alarm conditions.

SCADA系统是高分布式系统，经常用于控制地理上分散的资产，分散在数千平方公里，其中集中的数据采集和控制至关重要到系统操作。它们用于配水系统，如配水和废水收集系统，油气管道，电网和铁路运输系统。

一个SCADA控制中心长期对现场进行集中监控通信网络，包括监控报警和处理状态数据。基于信息从远程站接收到的，可以将自动化或操作者驱动的监控命令推送到远程站控制设备，通常被称为现场设备。现场设备控制本地诸如打开和关闭阀门和断路器的操作，从传感器系统收集数据，以及监控当地环境的报警条件。
