ECMS-4000 electricity measurement system

The ECMS-4000 is a complete on-board Energy Measuring System (EMS) per EN 50463, composed of a Data Handling System (DHS) and one or more Energy Measurement Functions (EMF). It collects, produces and stores energy billing data in a format ready for transmission to an authorized recipient on board or on a ground server.

The DHS regularly reads the load profiles of the connected EMFs, attaches time and position data, and compiles Compiled Energy Billing Data (CEBD) records. The records are transmitted automatically to a ground Data Collecting System such as the ECC-4000 using the protocol defined by EN 50463-4.

Functions

Reads energy data from the load profiles of connected EMFs, typically at a one-minute period
GNSS positioning read at one-second intervals, with position type and quality flags
Time synchronization with time-change recording and quality flags
Compilation of CEBD records with attached time, position and quality attributes
On-board record retention of 75 days (EN 50463 requires at least 60 days)
Automatic data transfer per EN 50463-4 over HTTP, HTTPS, FTP or SFTP, including the RequestCEBDBlocks, AutomaticTransferCEBDBlocks and AutomaticTransferHeartbeat services
Message encryption with AES-128-CTR using a per-message initialization vector; metrologically relevant data digitally signed during transmission
Built-in web interface: status, EMF data, records, export, setup and logs

Standards and terminology

The ECMS-4000 implements the EN 50463 series (railway applications — energy measurement on board trains): EN 50463-1 (general), EN 50463-2 (energy measuring), EN 50463-3 (data handling), EN 50463-4 (communication) and EN 50463-5 (conformity assessment).

Term	Meaning
CEBD	Compiled Energy Billing Data
CPID	Consumption Point Identification
DHS	Data Handling System
EMF	Energy Measurement Function
TRP	Time Reference Period
OBIS	Object Identification System
