Locomotive Ethernet Switch

As a simple managed Ethernet Switch, the CRM ESW resides at LDARS 10.255.255.253 where the ESW can be configured and where the customer can query the ESW for port connectivity metrics for example. The ESW is part of the CRM Enabling Technologies suite of products whose focus is to allow customers to leverage their own networks and data mining infrastructure to connect to on-board sensors.

The ESW is designed as a cost-competitive and space-sensitive approach to address the increasingly common issue of adding sensors to locomotives and bridging the sensor data to the on-board network. The ESW conveniently normalizes digital, analog, and serial sensor telemetry to the Ethernet network, where sensor data can be readily consumed by predictive maintenance algorithms, for example. The ESW supports license-free Class C broadcast of all raw sensor telemetry, and also supports AAR ITCSM.

The CRM ESW supports a completely self-contained and standalone acoustic fuel sensor interface for precision fuel management applications, including the power interface. The software configurable inputs can be configured for a wide range of custom user alerts and statistics. Combined with other customer-specified sensors, the ESW can be configured to be an extremely powerful yet compact standalone analytics platform, especially for legacy fleets. Combined with the CRM Locomotive Network Interface (LNI), a compact edge-processing platform enabled with GPS, WiFi and cellular, the ESW can be part of a flexible and low-cost analytics and asset monitoring solution.

The software configurable inputs can be configured for a wide range of custom user alerts and statistics, such as:

• Engine Run and Duty Cycle
• Hard Hit (accelerometer-based)
• Fueling Events
• Engine Temperature
• Battery Voltage/Health (i.e. cranking voltage) etc.
