To provide an effective means of transporting large populations safely and in a timely manner to their destinations, extensive data collection that is accurate, reliable and real-time is required. Therefore, the most critical component of a passenger rail’s automated system is its industrial networking infrastructure or backbone. This infrastructure connects components such as crosswalks, message display signs, PA systems, automated ticketing kiosks, train status displays, and cameras. Edge level network connections must be able to satisfy serial, Ethernet, fiber optic and wireless needs. All data from these edge devices need to be communicated in real-time between stations, traffic intersections, and other outside areas that may come into contact with the rail system. Due to heavy vibration, connectivity devices that utilize M12 connectors greatly mitigate the chances of lost connections. If there are failures within a segment of the infrastructure, the effects can quickly propagate causing delays.

Video surveillance technology plays an important role in improving security at many facilities worldwide. Statistics have shown that 80% of criminal acts reported to police at public centers and business offices occur in parking lots. To deter vandalism, theft, and other crimes, facilities are deploying video surveillance as part of a full range of security measures to remotely monitor/access/control site equipment from a central location.

The latest generation of machine vision systems offers significant improvements by incorporating industrial Ethernet switches and other Ethernet devices. This enables direct communication between PLCs, robot controllers, PCs, and human machine interfaces (HMIs). However, there is still serial-based equipment, such as sensors, readers, cameras, and vision systems, that cannot be easily networked.

Antaira’s M12 series of industrial switches do all of the below, as well as provide dust and water tight connections allowing the industrial Ethernet switch to be mounted in places where few other devices would survive. While this solution would run all on its own, a wireless radio can be added to the solution to transmit the general health of the vehicle when it returns to the barn for refueling or recharging.
