Suburban railway traffic monitoring system
Application Name – Suburban railway traffic monitoring system
Market – Transportation
Place – Moscow region, Russia
Moscow – Aleksandrov suburban railroad is the most heavily loaded direction of the Moscow Railway hub, it transfers more than 340 thousand passengers per day. Annually increasing passenger flow demanded the up-to-date flow control. So, on June 18 2012 the first Technological center for suburban passenger transportation was opened.
The described system is built on the railroad safety monitoring network, which contains various controllers and sensors for collecting data and a stage monitoring post for processing realtime information. Railroad safety monitoring network overwatches for the condition of every element of rail network and can supply its data to other system for various usage.
Technological center for suburban passenger transportation is dedicated for line-wide timetable control, preparation data for passenger information systems and incident logging.
Field data is aggregated at PICMG 1.0 – based stations, which are built in IPC-610 chassis. PCA-6178, PCA-6010, PCA-6012 CPU boards are mostly used here.
Field level communications are made with PCL-745, PCL-846, PCL-741 and PCI-1611 for RS-422/485 and “current loop” and PCL-841 and PCI-1680 for CAN bus. Upper level communications use TCP/IP.
For software part – QNX 4.25 is used.
Technology center contains it’s own dispatch center. Here all the trains are monitored, and personnel can check if every train is going along with it’s schedule. System also calculates the daily KPI of current shift – number of planned and completed routes, and how many trains are late. If train is going late for more than 5 minutes – the appropriate incident report is automatically created for further investigation.
Also, this traffic information is supplied for information displays, which are controlled with UNO-1150. These displays are placed on the platforms and near ticket-offices. Later, the ticket vending machines and station gateways will be connected to this center.
Mainbenefits of the system are:
• Systems provides personnel and passengers with up-to-date and reliable information
• System is partly built on existing hardware and software and is capable of reusing of the primary information
• System is capable for future extension
