SCADA system real-time data and event management on a PC card

摘要

Real-time data and event management (RDEM) is implemented on a separate component in supervisory control and data acquisition (SCADA). To assist in upgrades or changes to the SCADA system without compromising RDEM, the RDEM function is performed on a separate card or physical component. When the computer running the SCADA system is upgraded, the RDEM on the separate card and corresponding persistence store is maintained.

主权项

1. A system for real-time data and event management (RDEM) in supervisory control and data acquisition (SCADA), the system comprising:
a plurality of sensors; a plurality of actuators; a SCADA device for industrial control using the actuators and based on input from the sensors, the SCADA device including a first processor and a first card connector; and a computer card having a memory and a second processor, the computer card operable to connect with the first card connector and configured to implement the RDEM for SCADA with communications with the first processor through the first card connector, the memory of the computer card storing state information of the sensors and the actuators during implementation of the RDEM for SCADA, the SCADA being by the SCADA device.
