机车 Interface Gateway (LIG)
机车 Interface Gateway (LIG) is a network communications 和 interface device that provides locomotive control-system data to third-party applications. The LIG is designed with an Open 消息 Interface which allows applications to access control-system data while providing locomotive system isolation to ensure the control system is not adversely impacted by third-party applications. The real-time parameters available from the LIG can be used to perform real-time health 和 status monitoring of a locomotive as well as real-time assessment of locomotive operator performance.
主要特点:
- Provides locomotive control system data to 3rd-party applications via open message interface (PTC, 机车 Monitoring 和 Diagnostic, other RR Business Apps)
- Converts data from locomotive-specific format into an AAR-defined common format
- Provides 机车 Control System isolation from 3rd-party systems
- Streaming broadcast of locomotive parameters (cab st和 states, sensor readings…)
- Publication rates range from once per second to once per 60 seconds
- Request based 和 streaming locomotive fault 和 snapshot information
