Smart IP Video Surveillance Makes Railroad Crossings Safer
High-traffic railroad level crossings remain a global safety concern despite the widespread use of active warning systems to clear the tracks for oncoming trains. Although most train-and-car collisions are highly preventable, both real-time status and image about railway level crossing area and warning devices are required to help car drivers and pedestrians, railway operators, and local authorities avoid accidents. Transportation and safety professionals are increasingly deploying IP video surveillance technologies to provide real-time information to make existing level crossings smarter and safer.
· Real-time obstacle detection
· Around-the-clock asset monitoring
· Non-stop network video recording
Advanced CCTV cameras designed for harsh, outdoor environments are used in smart level crossings to provide 24/7 video surveillance for the clearance zone. In addition, state-of-the-art network video recorders are also installed in the wayside cabinet to store video streamed from the cameras so that accident investigators can replay the events leading up to a collision and identify its cause. In this scenario, Moxa’s VPort 36-1MP rugged IP cameras are used to capture and encode real-time video of the clearance zone, which is then streamed to an MxNVR-IA8 industrial network video recorder inside the wayside cabinet. In addition, Moxa’s IVA (intelligent video analysis) software application increases efficiency and protection coverage by using triggered alarms, such as the following:
● Camera Tamper: Triggered when the camera lens is blocked, redirected, defocused, or painted.
● Virtual Fence: A virtual “tripwire” in the camera frame will trigger an alarm whenever motion across the line is detected.
● Alert Zone: Any motion detected inside the detection zone will trigger an alarm.
● Removed Object: The camera detects whenever an object is removed from the frame, and will trigger an alarm after a certain user-defined time threshold.
● Unattended Objects: Tracks moving objects in the camera frame and detects abnormal loitering.
Although the principal image processing technology that makes the above solution so “smart” is Moxa’s IVA software application, the CCTV cameras and network video recorders deployed also need to be ruggedly designed with industry certified reliability.
l Rugged Design: wide operating temperature range of -40 to 75°C,
l Industry Certified Reliability: EN 50121, EN 55022, UL/cUL Class 1 Division 2, ATEX Zone 2, and NEMA TS2 certifications for electrical equipment used in railway applications
l Intelligent Video Analysis (IVA) for automatic obstacle detection
ü People entering the level crossing at any time
ü Any moving object other than trains identified on the track
ü Objects abandoned at trackside
ü Large metallic or organic objects on the tracks, such as logs, shopping carts, or a motorcycle
ü People crossing the railroad tracks
