Introduction
The LAX-GM-ER-9 Event Recorder is a cutting-edge system designed for capturing and storing a comprehensive set of parameters from Diesel Electric locomotives, specifically tailored for General Motors, ALCO, and Alstom Diesel Locomotives. This system receives data from the main locomotive computer via RS 485C (SAEJ1708) or Ethernet and records it into non-volatile memory. It ensures a reliable and accurate record of various critical locomotive events, enabling detailed journey and trend analysis for operational safety and performance monitoring.
System Overview
The LAX-GM-ER-9 Event Recorder records up to 45 locomotive parameters, including speed, power, brake pressure, and tractive effort. The system stores data in both short-term (72 hours at 1-second intervals) and long-term (90 days at 20-second intervals) memory, ensuring redundancy for post-incident analysis. Recorded data can be easily downloaded via various interfaces such as USB, Compact Flash Card, or RS232 port for detailed review and trend analysis. The system’s robust design offers zero maintenance and high reliability, operating in harsh environments with minimal oversight.
Application
- Journey Data Recording: Captures data for WDP-4 & WDG-4 type locomotives, including parameters like speed, brake pressures, and tractive effort.
- Trend Analysis: Facilitates locomotive trend analysis in case of incidents, helping identify operational issues.
- Performance Monitoring: Records critical data with time stamps for performance evaluation and incident investigation.
