Looking back to my previous entry, I realized that what I share was a bit technical (maybe for my classmates) although I have tried to simplify it by elaborating on the basic architecture of the system only.
So for this entry, I will try to simplifying it even more by relating the scada system to two Hollywood films which I saw adopt the scada system.
As was previously mentioned, the Supervisory control and data acquisition (SCADA) is basically a system for remote monitoring and control. This system is being widely used in the utilities, industrial, infrastructure, and facility-based industries.
The first film that has scada system in the film environment is “The Taking of Pelham 123”. It is a 2009 American thriller film directed by Tony Scott, and starring Denzel Washington and John Travolta. The story involves armed men hijack a New York City subway train, holding the passengers hostage in return for a ransom, and turning an ordinary day's work for dispatcher Walter Garber into a face-off with the mastermind behind the crime.
Next one, Unstoppable is a 2010 American disaster thriller film directed by Tony Scott, written by Mark Bomback, and starring Denzel Washington and Chris Pine. The film, loosely based on the real-life CSX 8888 incident, tells the story of a runaway freight train, and the two men (Washington and Pine) who attempt to stop it.
So...If you have seen these two films, you may have noticed a similar scene when the managers /operators in charge in the control center, trying to make sense of the situation in each of their film by looking to the information displayed in the big screen in the room.
These two scenes are the perfect examples of real life application of scada system. By using this system, the operators in the control room can monitor the location of their train, remotely change the routing track, planned and manage the overall operation of its day to day business needs.
For better understanding of the system application, I highly suggest that you watch these movies and try to pay attention to their control room work setting.
