Modular system platform for rolling stock applications

REQUIREMENTS AND IMPLEMENTATION

The HeiSys system platform combines the advantages of available and established plug-on modules and offers on the one hand full scalability in computing power and on the other hand multidimensional modularity regarding communication and I/O interfaces. 

Depending on the complexity of the design and the re-quirements for bandwidth, signal diversity, performance and power consumption, appropriate COM Express boards can be selected and thus the computing power scaled. By combining the COMe processor module with a standardized FPGA SMARC module and the associa-ted FPGA design, the greatest possible variance of requi-red interfaces can be mapped. This eliminates the need for complicated, time-consuming design or the complex  coordination of a wide variety of components. 

Full flexibility with regard to wireless transmission techno-logies is ensured by the use of standardized and future-oriented M.2 interfaces. The system platform is designed for the use of Wi-Fi, LTE, 5G, UMTS, GSM, LPWAN (LoRa-WAN, etc.), Bluetooth, GPS GLONASS multi-band radio modules for use in railroad operations. 

The EN 50155 approval means that the compact system is certified for mobile use as rolling stock or for wayside monitoring. Due to the absence of moving parts such as fans, the reliability and the MTBF is significantly increa-sed. The system guarantees operation in the extended temperature range between -40 °C and +85 ° C. Here, the system can take over the tasks of a gateway, a passenger information system, a wireless access point, among other things, or even act as a diagnostic and monitoring tasks on the train. HeiSys supports Windows 10 / IoT as well as all Linux distributions with current kernels. The con-cept uses main line drivers or the drivers provided by the corresponding modules to ensure smooth commissioning and operation. 

HEITEC offers its customers a flexible system platform that can be individually adapted and which, due to its upgradeability, is a secure and cost-efficient investment in the long term.
