Aeroexpress uses its PSIM solution to monitor all aspects of its operations in real-time, whether related to safety, security or passenger service. Through integration with crowd detection video analytics, the PSIM system lets operators know when there’s excessive congestion at exit turnstiles or ticket counters. Aeroexpress also uses PSIM’s integrated reporting capabilities to track and document maintenance issues, regulatory compliance violations, and incidents that require assistance from external agencies.
Another example comes from a driverless sky train operator in a large international airport that recently deployed PSIM to optimize operations for a closed loop, private system they built and manage. The operator is bound to a service level agreement requiring very high levels of availability. If the service levels aren’t met, substantial fines can be imposed. To minimize this financial exposure, the sky train operator implemented a PSIM solution that enables its personnel to respond faster to incidents, thereby minimizing downtime. For example, if a train car is stranded on the tracks, control room operators are immediately alerted through the PSIM system by information coming from the SCADA, as well by help buttons activated by passengers onboard the train. The operator is presented with the GIS location of the train, and live video feed from onboard the train as well as from the nearest tunnel camera. The operator’s response to the situation is guided by best practices that are aligned with airport emergency procedures (AEP).
The solution was put through its paces during the past Christmas holiday season when a packed train was stranded on the tracks. Thanks to the PSIM solution, the operator was able to quickly evacuate the passengers from the stranded train, send status updates to airport officials as required by airport regulations (every 5 minutes), and resume normal operations much faster. Through on time reporting the operator was able to avoid fines, and the quick return to normal operation satisfied the stringent SLA requirements.
Of course the PSIM system is also being used for security, but its main purpose is to ensure that any technical or operational incidents are identified and resolved in the shortest time possible, because every second counts — literally. Fines for not complying with the service level agreement are calculated by the second.
Video Analytics are Advancing Too
Thanks to the latest generation of Video Analytics (VA) applications, video surveillance solutions are more accurate, more intelligent, and able to serve more purposes in more places than ever before. Nowadays, VA applications are just as much about what they don’t alert you to as what they do alert you to. While the latest versions are based on the same concept of detecting and alerting, they generate significantly fewer false alarms and do so without compromising detection rates.
Object classification is also more sophisticated and accurate than ever before. Advanced object classification video analytics software is able to differentiate between different types of moving things, such as a human or a car. It can filter out irrelevant objects/elements, such as moving vegetation, a shaking fence, shadows, and car lights. With the ability to classify objects more precisely, video analytics are better able to distinguish true threats from false alarms.
India’s Bangalore Metro is in the process of implementing Video Analytics for automatic intrusion detection at select locations along its tracks and in restricted areas. The Metro is also in the process of deploying a VA application for crowd control that will monitor overcrowding and queue wait-time at stations. The different applications can run on the same camera.
From intrusion detection to crowd management, VA applications can be leveraged for a wide range of purposes beyond security. Video Analytics can also be layered into a larger PSIM solution, as one element of a complete situational awareness picture, along with other sensors and systems.
Closing the Loop — Leveraging Big Data for Investigations
PSIM integrates, analyzes and correlates the big data flowing into the control room for real-time situational awareness, but there’s still another question to consider — how can you effectively leverage all of this information for investigations later on?
