  1. Data Collection Software Solution Electrical Energy and Diesel Fuel Metering Systems Typical TEMS-BVT graphics • A server hosting service, TEMS-BVT, is available that providesa complete Data Collection Service software solution.This solution includes a server hosted in the Far Systems data-centre, an FTP server, a WEB server, a Database server and a web-based application to allow access to the data anywhere using a PC, an internet connection and a web browser (i.e. Microsoft Internet Explorer). • This software provides: • Access to each single point of measure • Viewing of recorded data in table and graphic mode. • Viewing of the position of the recorded samples on a maps (where GPS data are available) • Data export in XML or CSV file format. • The portal allows graphical analysis of data collected from on-board metering systems. The system also configures the data ready for printing reports and export of the data in formats compatible with most commonly used software e.g. Microsoft Excel and Microsoft Access. Energy usage on trains is increasingly being scrutinised to deliver cost efficiencies.  To enable a train-by-train comparison, an accurate method of measuring both diesel and electrical fuel consumption is needed.  Both invasive and non-invasive systems are designed to give immediate accurate information for data analysis and to identify options for train systems or operational improvements. Diesel Fuel Metering The Train Fuel Measurement System (TFMS) monitors and measures the fuel consumption of railway diesel engines. Each vehicle with a diesel engine is equipped with a TFMS consisting of 2 fuel sensors, and the RFM100 meter (Railway Fuel Meter). Two kinds of fuel sensors are available, non-invasive ultrasound clamp–on sensors and spindle tube in-line sensors. In both cases two sensors are used per engine, one for the manifold flow and one for return. The recorded engine consumption is the difference between the flow rate and the return. Electrical Energy Metering The Train Energy Meter System (TEMS) monitors and measures the actual consumption of energy used in electrically powered trains. The REM101 reads the voltage and current values provided by the transducers and calculates the energy used in real-time in accordance with EN50463. The REM101 is able to measure 25kV-50 Hz, 15 KV-16,7 Hz and DC energy systems with a metering accuracy of class1 or better. Energy values are stored in the on board memory. The load profile recording resolution is selectable for periods of 1, 5, 10 and 15 minutes.

  2. TEMS & TFMS SYSTEM FUNCTIONAL BLOCK DIAGRAM Electric Metering • The integrated meter display allows for easy interaction by the operator. Various data groups can be accessed in this manner e.g. • energy samples • accumulative energy value • train location/time, • Auto-diagnostic alarms • service messages • Measured Energy data can be downloaded through an Ethernet or Isolated Serial Interface available at the front panel without any preloaded software (using a typical web browser). • The REM101 can also exchange data via an optional embedded GSM/GPRS interface, This provides the connection between on-board equipment and ground control centre. • As an option the metering system can also be equipped with an internal GPS receiver to correlate location, date/time data with stored energy values.

The overall system accuracy is dependent on parameters such as engine consumption, pipe diameters, fuel temperature/viscosity variations and the type of sensors employed. • The REM101 provides the following functions: • Measurement and storage of periodic and instant energy consumption plus regenerative data • Combines the energy consumption data with GPS data • Transfers data via GSM/GPRS to the Data Collection System server • Guarantees precise energy billing data collection • Allows monitoring of the train and fleet energy consumption • Allows energy consumption optimisation In-line fuel sensor *Assumes 15h/day service : 5 h/day in idle, 4 h/day in half load, 6 h/day in full load. Idle = 0.1l/min, full load = 5.2 l/min
