Dominion Electronics are the distributors for MEN Micro’s Automated Train Operation Control and Supervision system. This system comprises of features such as:
- 19" system with redundant electronics
- 3U CompactPCI SBCs F11
- Celeron III, 650MHz
- 256MB DRAM, 2MB SRAM
- 2 Fast Ethernet, 1 COM, 2 USB
- FPGA with watchdog and COMs
- SA-AdapterT carrier board F206
- FPGA with 8 RS422/HDLC interfaces
- Customised I/O board
- FPGA with miscellaneous I/O
- Linux and proprietary OS
Besides the safe and quick transport of thousands of people with trains that stop at the station precise to the centimetre without interaction of a driver, driverless trains can also be optimised in speed and energy consumption. Depending on the project up to 500 mobile and stationary control and management systems are needed to monitor the train on a line.
In this application the control and monitoring system provides a response channel that allows the permanent transmission of status data of the vehicles back to the control centre.
The redundant CompactPCI computer systems consist of standard Pentium III based single-board computer in single Eurocard format. It features a low-voltage Celeron with 650MHz clock frequency, two Fast Ethernet and two serial ports. The serial interfaces and an additional watchdog are implemented as IP cores in the on-board FPGA.
The second card in the system comes with eight additional serial interfaces which are all realised in FPGA and which work in asynchronous RS422 mode and in synchronous HDLC mode.
Another card delivers the remaining I/Os required in the system, consisting of digital I/O channels, analogue outputs, counter pulses, a radar sensor to pick up data from the route sensors and interrupt inputs. All these functions are again configured in the on-board FPGA.
If required in a project, an MVB (Multifunction Vehicle Bus) field bus interface card can also be plugged on a mezzanine carrier board.
The complete electronics is screened for an operation temperature of -40 to +85 °C and coated against humidity and dust.
