Measurement and minimization of vibrations and noise
Microphone arrays and vibration sensors combined with an edge control system can be used to reduce the noise generated by trains and trams on curves. Mobile rail head and flange conditioning systems can be addressed by our hardware. In addition, damage to the wheels (e.g. flat spots) and rails can be detected and proactively prevented, which can lead to a drastic reduction in operating costs.
Mobile remote access and management of controls
In 2018, Parametric equipped a fleet of over 70 commuter trains in South Australia for ABB with RAR4 computers and our solution for mobile, secure remote access via the mobile network. The devices run software that also performs control tasks. The trains were refitted in a new depot in Adelaide, and remote maintenance was also installed. The data can now be used to optimize operations.
Streaming video data to legacy systems in vehicles
Information screens in trains and buses are sometimes still equipped with older hardware that does not understand newer streaming formats such as H.264. Our systems, which have been used by Livesystems since 2014, download highly compressed content from the mobile network and serve the systems with streaming data. All of this is extremely compact and with minimal energy consumption of 5 watts, and therefore extremely easy to integrate, especially in refit projects.
QoS monitoring of ultra low latency mobile networks
Remote control of vehicles requires ultra-stable mobile connections that, if possible, provide guaranteed bandwidth. Mobile networks are usually optimized for downlinks (consumption on the train), and the uplink bandwidth and latency vary greatly. For several public transport companies in Switzerland, we have carried out measurements in 5G and 4G TDD test networks as well as in tunnels and developed hardware that is suitable for autonomous monitoring of mobile networks and for streaming video with glass-to-glass latencies of < 130msec.
