Vehicle Monitoring System (VMS) relates generally to apparatus for collecting data from several inputs and particularly to microcomputer-based device for receiving these inputs.
Collected data could be recorded for subsequent monitoring or analyzed on real operation of the train by sending these data to the driver monitor or to a OCC.
With the aim of improve the safe and efficient operation of a train, it is important that the technical team of the operator could know all the different parameters of the train when it is moving: door, brakes, battery voltage, speed, position, status of each system, etc. It is important to keep a record, based on events, of such data so that management and maintenance personnel can properly assess the manner in which the train has been operating.
When the Monitoring System is able to act on the control of the train, the system becomes the brain train and it is called Train Control and Monitoring System (TMS)
