Safety - Critical Embedded Solutions for Railways
AC Controller Board for Trains
- Micro controller based Smart Controller system to monitor and control the AC sub system in the Indian Railways AC coaches.
- Designed and developed as per the RDSO specification.
- Approved by RDSO and installed in Indian Railways AC coaches.
- System consists of a Control Unit and a 7-inch TFT display Unit.
- Control unit monitors and controls the AC sub system by sensing the temperature and humidity.
- Faults and Events are stored in the non - volatile memory.
- All system parameters and faults are displayed in 7-inch TFT display. User buttons available for modifying the system configuration.
- Faults and Events are send through GPRS to server for Remote Monitoring.
- Modbus interface for external interface.
