On-board systems
On board the vehicle, the IBISplus G2 computer acts as communication centre for information and voice services between driver, passengers and control centre. As the central computer system, it integrates a wide range of different vehicle components - from the radio via the ticket validator through to the multimedia system. Its conception and features are tailored to road and rail vehicles operating within public transport networks.
IBISplus G2 is a further development of our tried-and-tested IBISplus on-board computer. More than 40,000 of these on-board computers are operating for our customers every day all over the world.
IBISplus G2 is based on an efficient core with low power loss. The unit generates little heat, providing the basis for a long service life. Its compact design takes account of the usual lack of space to be found in the vehicle. As an option, a specially protected version has been developed in the IP65 standard for use in demanding conditions.
Control units
The driver operates the IBISplus G2 on-board computer at the mobile touch terminal (MTT) or mobile data terminal (MDT). Existing hardware and software interfaces permit integration of input and display units from other manufacturers.
Voice and data radio
IBISplus G2 simultaneously supports up to three radios with voice and data functions. A digital signal processor is available as an option for data modulation via analogue radios. Together with the integrated acoustic module, the on-board computer activates up to three loudspeaker circuits. Other integrated features include WLAN, GSM/GPRS, CAN, Ethernet switch, configurable digital I/O (input/output) and USB.
An internal fall-back controller checks the functions of the IBISplus G2 (watchdog). This guarantees the availability of voice and emergency services even if the on-board computer should fail. Train bus modules are available as add-on components, together with external WLAN, UMTS router (GPR) and analogue and digital radios.
Use in trams
When used in trams, IBISplus G2 supports dual-head and traction operation/train bus) together with fast IP communication via the train bus using powerline technology. Integration of the electro acoustic equipment already present in the trams is also possible.
Interfaces
Up to six serial interfaces (combinations of RS232, RS422 or RS485), the VDV vehicle bus and Ethernet are also available for connecting up additional units. When it comes to ticket printers or other devices that need data to operate or forward data to a central system, the on-board computer acts as a router or provides corresponding capacity in its memory.
Power management/supply
IBISplus G2's power management comes into play when additional components are integrated. It automatically switches two external load circuits on or off. It goes automatically to a power-saving sleep mode to protect the vehicle batteries. It switches itself on again for data exchange or when the ignition is activated.
Passenger count
A reliable reading of passenger load in the vehicle (for example by infrared movement sensors) allows better planning of vehicle deployment and optimisation of the timetable. In addition, the passenger count represents an important basis for the division of earnings within a multi-agency organisation.
Vehicle location
Vehicle location is based on a combination of logical location, satellite-based location using GPS and physical location.
