IP networks in buses

The Ethernet technology is also present in the public transportation. Especially in buses, trams and metros Ethernet based networks are more and more preferred. The reason is that the data volume has increased
significantly over the years. Traditional communication protocols such as the IBIS protocol in buses provide
limited bandwidth to transfer video data in surveillance applications. Power over Ethernet (PoE) is used to cut cabeling and installation costs.

In public transportation vehicles different network participants must be connected. Those can be cameras for surveillance of the passenger compartment or passenger countig systems and dynamic passenger information systems . Further you‘ll find video recorder systems, LTE router and a central board control unit in buses. Further modern buses provide e-ticket validators. All those devices have to be connected into a common system.

With the special designed M12 Ethernet Switches for public transportation it is easy to connect all network participants. By using the Ethernet technology, manufacturers of public transport vehicles are able to cut costs for cabeling. And on the other hand they are able to provide first class services to their passengers. Such as cashless payment systems, public WiFi, dynamic passenger information or video surveillance for  more onboard safety.

Your benefits

  • Standardized and future proof solution with IBIS-IP, ITxPT compliant products
  • Enables you to use a wide range of passenger services
  • Dynamic passenger information systems
  • Faster diagnosis and repair in event of failure
  • Use of passenger counting systems for optimized fleet management
  • Improvement of passenger services e.g. WiFi,
  • Cutting installation and cabeling cost by using PoE
  • Remote accessability and diagnosis

Clean network for clean video data


Problem 

In public transportation vehicles different network participants must be connected. Those can be cameras for surveillance of the passenger compartment or passenger countig systems and dynamic passenger information systems. Further you‘ll find video recorder systems, LTE router and a central board control unit in buses. Further modern buses provide e-ticket validators. All those devices have to be connected into a common system. At the same time all the different services must be separeted and priortized in the IP network, but how?

Solution with VLANs and Quality of Service

With Virtual LANs physical connected devices are seperated logicaly in the network. Further QoS provides a simple possibility to priortize datastreams of certain IP components. 

Your benetifs:

  • Flexibility with standardized technology IBIS-IP, IPxPT
  • Enables you to use a wide range of passenger services in one network
  • no extra hardware is needed
  • better network and data quality

Secury IP networks for modern paying systems


Problem

Modern paying systems require secure IP networks. Paying concepts like check-in check-out in combination with cashless paying methods like credit card require high IT security. The sensible data such as credit card number or personal data of payment must be handled in a private network, hidden from all other network services such as passenger information systems, but how?

Solution with Firewall/NAT Switch

To hide a private network we recommend to have an Ethernet Switch with integrated NAT and Firewall features. With the NAT functionality a network is divided in two different subnetworks. Thus the private network devices are invisable for the vehicle network. Further a Firewall can be configured to reject or drop all incoming inquiries.

Your benefits

    • security to sensitive paying data
    • enables to use modern on-vehicle-services
    • cut of acquisition and maintenance costs

    Automatic IP-configuration of IP networks in buses

     

    Problem
    In buses different systems such as video surveillance, passenger information, control unit, ticket validator or passenger counting systems must be interconnected. The configuration of the IP addresses has to be automatic to have minimum downtime and costs in case of a repair in the shop floor. After a replacement the new IP device must automatically get the same IP address as the previous one.

    Solution: Switch with DHCP Option 82
    For the automatic IP address configuration we recommend to use the ROQSTAR Full Managed Switch as a DHCP server. The Switch assigns IP addresses from an IP address pool to all connected devices. To set static IP addresses based on the connected port the DHCP Option 82 is used. In a simple table you can assign static IP addresses to a defined Ethernet port.

    Ihre Vorteile

      • minimize downtime in case of repair
      • easy way to set up complete bus fleet
      • cut of installation and configuration costs by reducing manual work
