Advanced On-board Bus ITS Systems Support Smart City Design
In building components for advanced ITS systems, Duragon Systems has concentrated in developing technologies and innovative solutions for bus and railway ITS applications. Traditionally, on-board systems on buses have been splintered, consisting of a mix-and-match of many devices from multiple vendors, making maintenance, service and integration a challenge. Some vendors of "low-cost systems" just include these devices into a single enclosure with no further integration nor system design.
Though at first the consideration may be the purchase price, the cost of ownership of such a solution can become high, and reliability and functionality can be compromized. Duragon Systems has taken a top-down approach into creating a platform, which combines all the common requirements of a modern high availability Bus ITS system into one device based on full system design.
Duragon can offer a seamless 5G upgrade for existing ITS systems, which typically base on a vehicle PC with in-built cellular modem. The upgraded features offered by the DURION-DR01 router include high accuracy DR-assisted GNSS navigation and a Layer 3 5G-router integrated with a dedicated Quad Core ARM "Bus-Computer".
The integrated DURION controller, referred to as a "Single Control Unit-SCU" includes:
- Purpose-built low power high performance computer with solid state storage
- System management, monitoring and failure recovery microcontroller
- Latest LTE modem for mobile connectivity
- Multi-constallation DR-assisted GNSS receiver with IRNSS support
- High speed 802.11ac WiFi for depot-area networking
- Bidirectional audio emergency voice call
- 4 or 8-channel DVR
- J1939-interface for vehicle data acquisition from ECU
- Isolated Digital I/O for direct vehicle signal interfacing
- Inbuilt CODEC and stereo amplifiers for announcements and infotainment
- 10/100Mbit Ethernet for in-vehicle ITxPT communication or IP-cameras
- Serial ports (RS-232 and RS-485) for AFC system or LED display interfacing
- Digital driver console display interface
- In-vehicle peripheral power conditioning and distribution
The DURION-DR01 5G Bus Router-OBU Includes:
- Low power high performance Quad Core ARM Linux computer
- Mediatek MT7621A WRT Linux networking processor
- System management, monitoring and failure recovery microcontroller
- Latest sub 6GHz 5G-modem with eSIM and uSIM support
- Optional 802.11ax/ac WiFi (Access Point and Client)
- Multi-constalltion DR-assisted GNSS receiver
- 4x External Gbit Ethernet ports (RJ45 or M12)
- J1939 CAN, 2x RS-485, RS-232 and Digital I/O, 3D accelerometer
- FAKRA connectors for GNSS and modem antennas
- 8 - 36VDc Power input
- ECE REG 10 and ISO 16750-3 Compliant
Integrating On-Board Systems
The advantage of using an SCU, is the simplification of on-board ITS systems integration and as a result, reducing overall cost in both modernization and new-production installations. Software development and maintenance is simplified, and service is easier to manage. The DURION BUS-PC is an uncompromizing purpose-built system covering all bus transportation applications, combining all interfaces, peripherals and required power supplies into one.
