# SA4CPS FTP Data Ingestion Service
|
||||
|
||||
This service monitors the SA4CPS FTP server at `ftp.sa4cps.pt` and processes `.slg_v2` files for real-time energy monitoring data ingestion.
|
||||
|
||||
## Overview
|
||||
|
||||
The Data Ingestion Service provides comprehensive FTP monitoring and data processing capabilities specifically designed for the SA4CPS project. It automatically detects, downloads, and processes `.slg_v2` files from the FTP server, converting them into standardized sensor readings for the energy monitoring dashboard.
|
||||
|
||||
## Architecture
|
||||
|
||||
```
|
||||

|
||||
- ✅ **Smart Header Detection**: Automatically detects and parses header information
|
||||
- ✅ **Metadata Extraction**: Processes comment lines for file-level metadata
|
||||
- ✅ **Unit Inference**: Intelligent unit detection based on column names and value ranges
|
||||
- ✅ **Timestamp Handling**: Supports multiple timestamp formats with automatic parsing
|
||||
- ✅ **Multi-Value Support**: Handles files with multiple sensor readings per line
|
||||
|
||||
### Data Output
|
||||
- ✅ **Redis Publishing**: Real-time data streaming via Redis pub/sub
|
||||
- ✅ **Multiple Topics**: Publishes to 3 specialized channels:
|
||||
- `sa4cps_energy_data`: Energy consumption and power readings
|
||||
- `sa4cps_sensor_metrics`: Sensor telemetry and status data
|
||||
- `sa4cps_raw_data`: Raw unprocessed data for debugging
|
||||
- ✅ **Standardized Format**: Consistent sensor reading format across all outputs
|
||||
|
||||

|
||||
```
|
||||
|
||||
### Extending File Support
|
||||
|
||||
To add support for new file formats:
|
||||
|
||||
1. Add format to `DataFormat` enum in `models.py`
|
||||
2. Implement `_process_your_format_data()` in `data_processor.py`
|
||||
3. Add format handling to `process_time_series_data()` method
|
||||
4. Update `supported_formats` list
|
||||
|
||||
### Custom Processing Logic
|
||||
|
||||
Override processing methods in `DataProcessor`:
|
||||
|
||||
```python
|
||||
class CustomSA4CPSProcessor(DataProcessor):
|
||||
async def _process_slg_v2_line(self, line, header, metadata, line_idx):
|
||||
# Custom line processing logic
|
||||
processed = await super()._process_slg_v2_line(line, header, metadata, line_idx)
|
||||
|
||||
# Add custom fields
|
||||
processed['custom_field'] = 'custom_value'
|
||||
|
||||
return processed
|
||||
```
|
||||
|
||||
## Support
|
||||
|
||||
For issues or questions:
|
||||
1. Check service logs: `docker-compose logs data-ingestion-service`
|
||||
2. Verify configuration: `curl http://localhost:8008/sources`
|
||||
3. Test FTP connection: `curl -X POST http://localhost:8008/sources/{id}/test`
|
||||
4. Review processing status: `curl http://localhost:8008/processing/status`
|
||||

📁 Key Files Created/Modified:
|
||||
• data-ingestion-service/sa4cps_config.py - SA4CPS configuration
|
||||
• data-ingestion-service/data_processor.py - Added .slg_v2 support
|
||||
• data-ingestion-service/startup_sa4cps.py - Auto-configuration script
|
||||
• data-ingestion-service/models.py - Added SLG_V2 format
|
||||
• docker-compose.yml - Added data-ingestion-service
|
||||
|
||||
🔧 To Deploy and Run:
|
||||
|
||||
1. Build and start the services:
|
||||
cd microservices
|
||||
docker-compose up -d data-ingestion-service
|
||||
|
||||
2. Configure SA4CPS connection:
|
||||
docker-compose exec data-ingestion-service python startup_sa4cps.py
|
||||
|
||||
3. Monitor the service:
|
||||
# Check health
|
||||
curl http://localhost:8008/health
|
||||
|
||||
# View data sources
|
||||
curl http://localhost:8008/sources
|
||||
|
||||
# Check processing stats
|
||||
curl http://localhost:8008/stats
|
||||
|
||||
4. Manual FTP credentials (if needed):
|
||||
# Update credentials via API
|
||||
curl -X POST http://localhost:8008/sources/{source_id}/credentials \\
|
||||
-H "Content-Type: application/json" \\
|
||||
-d '{"username": "your_user", "password": "your_pass"}'
