Airborne Digital Recording System [ADRS]
The Airborne Digital Recording System [ADRS] is a component of the Power Line Maintenance Inspection System.
This system acquires and performs a digital, synchronized recording of inspection data from multiple sensors. Simultaneously, it provides multiple data streams, both from live and recorded data. By creating digital recordings referenced by time and geography, the system improves the availability of inspection data for the power lines life-cycle management.
The system can readily integrate with multiple video and audio channels, including video, thermographic and UV cameras, lasers and GPS sensors. Also, the system can accommodate other types of sensors by adding the appropriate data converters. The ADRS is the digital georeferenced equivalent of a recorder.
The Digital Recording system is operated via a web interface accessed with common browsers. This allows more than one operator to perform interactive inspection tasks independently without disturbing the live recording. Additionally, operators may annotate the recording using markers. This makes it possible to retrieve only the portion of video during which the operator was focusing on a hot spot, instead of having to browse through long recordings. Insofar as the recording is synchronized and the same system integrates multiple sensors, obtaining the data acquired simultaneously from other sensors is immediate.
All recorded data is stamped with a common real time clock reference and with geographical GPS coordinates. This way, every frame is associated to a specific location and time permitting data retrieval using both types of references. One advantage of the Digital Recording system is that it allows data to be extracted given a geographical reference, such as a rectangular region of a map.
The Digital Recording system web interface can be flexible and adaptable to address the specific needs of each organization. Not only can the interface features can be altered depending on the type of required mission data but the manner in which the data is presented in the interface can also be changed. This approach brings the Digital Recording system closer to the needs of maintenance and asset management databases, becoming not an additional system to which the organization must adapt to but a system which adapts to the organization.
