Telemetry systems allow remote measurement and reporting of information. In rolling stock applications these systems typically need to comply with EN 50155.
In an application in subways and streetcars, such a diagnosis computer monitors and logs data of the motor functions, the door-closing mechanisms and other functions that are reported to the depot during travel. The 3U CompactPCI® system is equipped with a modified Intel® Atom™ based F11S single-board computer using M12 connectors for the Ethernet channels. The power supply has its own intelligence for the shutdown of the system.
Another application supports real-time data transfers between train and shore-based systems for non-critical activities such as announcements, timetables, CCTV, location, alarms, etc. The CompactPCI® PlusIO system is based on an Intel® Core™ 2 Duo F19P single-board computer. It houses different platforms like a headless unit, a maintenance simulator platform, a shore server and a mobile gateway.
In a service application for high-speed trains, the railway carriage is connected wirelessly to the computer center of the operator via WLAN, UMTS, GSM-P and optional GSM-R. The new time-saving and resource-friendly system provides on-the-fly updates for seat reservation, diagnosis of the carriage, definition of the carriage and passenger information. The CompactPCI® system comes with a custom backplane and a 3U CompactPCI® PlusIO COTS F19P single-board computer. The Intel® Core™ 2 Duo card is equipped with a larger heat sink to handle environment temperatures up to +85°C and connects the Gigabit Ethernet channels via rugged M12 connectors. All wireless interfaces are implemented with two PCI Express® Mini cards on one F212 card with on-board diplexer. An F210 card adds the GSM-R option to the system.
