Wabtec Bach-Simpson Event Recorder

1 - Event Recorder

Meets and exceeds FRA, IEEE, GM/RT and EEIG crash protection standards
Today's rail transportation industry is more dynamic and complex than ever before. Rail transport companies are rapidly adopting high-tech solutions to help manage and maintain their fleet. Event data recording is a very effective solution that has been deployed throughout the rail transportation industry. Recording vehicle data is essential to operating and maintaining safe and efficient vehicles, and providing an effective health monitoring system.
Recorded data provides vital information for accident investigations, train handling studies, fuel conservation, vehicle performance, and preventative maintenance programs.
Bach-Simpson™ Event Recorders are engineered for maximum flexibility, meeting your immediate needs while allowing for future expandability. Bach-Simpson Event Recorders are complimented with a Windows® PC software package for service personnel to download and graphically analyze data from the Event Recorder.
A typical Bach-Simpson Event Recorder system is capable of monitoring and recording discrete frequency, analog voltage, digital input signals and Train-line network communications, as well as controlled outputs and optional features to support features that include a Train Monitoring (Alerter) System for operator alertness, remote download capability, speed display, auxiliary light control, horn sequencing, and various other control and monitoring functions.
The internal Crash Hardened Memory Module (CHM) meets or exceeds the latest FRA and IEEE 1482.1 crashworthy requirements for event recorders. This Crash Hardened Memory Module protects data from the most extreme conditions; Fire, Shock, Crush and Volatile Liquids.
The Train Monitoring System (TMS) or Vigilance/Alerter can be integrated within the event recorder, to ensures operator vigilance at all times. The TMS examines the engineer's control handling actions and will automatically bring the train to a stop should the engineer become incapacitated or unable to perform normal duties.
The Auxiliary Light Control consists of 2 sets of relay contacts for independent control of the Left and Right Auxiliary Lights. The operation of the two ditch light control outputs is user programmable for the auto mode flashing trigger source (Bell, Horn or both) and flashing rate and hold period timing parameters.
The Horn Sequencer responds to a single operator’s command to an external horn control relay, for providing the appropriate horn sequence activation.
