BeijingYounuoApiAppService Enhancement Summary

Overview

Enhanced the BeijingYounuoApiAppService class to provide business-oriented methods that follow SOMS patterns and perform data correlation and analysis before making external API calls.

Key Changes Made

1. Interface Implementation Fix

• Before: Implemented IBeijingYounuoApiService (which didn't exist)
• After: Now correctly implements IBeijingYounuoApi

2. Added Business-Oriented Methods

2.1 Equipment-Based Digital Twin Query

Task<RequestResult<List<BeijingYounuoDigitalTwinApiItem>>> GetDigitalTwinsByEquipmentAsync(Guid equipmentId, CancellationToken cancellationToken = default)

• Purpose: Query digital twin data based on equipment ID
• Business Logic: Constructs API query with equipment-specific filters
• Returns: RequestResult<T> following SOMS patterns

2.2 Equipment Alarm Management

Task<RequestResult<bool>> PushEquipmentAlarmsAsync(List<AlarmDataOutput> alarmDataList, CancellationToken cancellationToken = default)

• Purpose: Push alarm data using business objects instead of raw JSON
• Data Transformation: Converts AlarmDataOutput to Beijing Younuo API format
• Features:
  • Maps SOMS alarm levels to Beijing Younuo severity levels
  • Generates appropriate twinID based on business rules
  • Includes comprehensive logging

2.3 Equipment Alarm Synchronization

Task<RequestResult<string>> SynchronizeEquipmentAlarmsAsync(Guid equipmentId, List<AlarmDataOutput> alarmDataList, CancellationToken cancellationToken = default)

• Purpose: Complete alarm synchronization for a specific equipment
• Business Logic:
  1. Clears existing alarms for the equipment
  2. Pushes new alarm data if provided
  3. Provides detailed operation results

2.4 Data Correlation and Analysis

Task<RequestResult<List<MultiAttributeDigitalTwinDto>>> CorrelateDigitalTwinDataAsync(List<BeijingYounuoDigitalTwinApiItem> digitalTwinData, CancellationToken cancellationToken = default)

• Purpose: Correlate external API data with local business entities
• Features:
  • Transforms API data to business DTOs
  • Applies business rules and validation
  • Handles individual item failures gracefully
  • Provides detailed correlation results

2.5 Equipment Dynamics Data Push

Task<RequestResult<bool>> PushEquipmentDynamicsAsync(List<EquipmentDataModel> equipmentDataList, CancellationToken cancellationToken = default)

• Purpose: Push equipment telemetry and telesignaling data
• Data Transformation:
  • Converts EquipmentDataModel to Beijing Younuo dynamics format
  • Handles both telemetering and telesignaling data
  • Maintains data quality and timestamp information

2.6 Enhanced Connection Testing

Task<RequestResult<object>> TestConnectionDetailedAsync(CancellationToken cancellationToken = default)

• Purpose: Comprehensive connection testing with detailed results
• Features:
  • Tests Token authentication
  • Tests API connectivity
  • Tests Elasticsearch configuration
  • Returns detailed status information

3. Enhanced Error Handling and Logging

• All new methods follow SOMS patterns with RequestResult<T> return types
• Comprehensive error handling with try-catch blocks
• Detailed logging using Log4Helper at appropriate levels
• Business exception handling with meaningful error messages

4. Data Transformation Logic

• Alarm Level Mapping: Maps SOMS alarm levels (1-4) to Beijing Younuo severity levels
• TwinID Generation: Creates consistent twinID format based on equipment IDs
• Data Format Conversion: Transforms business objects to API-specific formats
• Quality Preservation: Maintains data quality indicators during transformation

5. Business Rule Implementation

• Equipment-based data filtering and correlation
• Alarm status management (active/inactive)
• Data validation and cleansing
• Timestamp standardization

Benefits of Enhancement

1. Improved Maintainability

• Business logic separated from API communication
• Clear method signatures that reflect business intent
• Consistent error handling patterns

2. Better Integration

• Methods accept business domain objects instead of raw JSON
• Proper data correlation with local equipment information
• Follows established SOMS architectural patterns

3. Enhanced Reliability

• Comprehensive error handling and logging
• Graceful handling of partial failures
• Detailed operation results for troubleshooting

4. Business-Oriented Design

• Methods designed around business use cases
• Data transformation based on business rules
• Equipment-centric approach to data management

Usage Examples

Push Equipment Alarms

var alarms = new List<AlarmDataOutput> { /* alarm data */ };
var result = await beijingYounuoService.PushEquipmentAlarmsAsync(alarms);
if (result.Flag)
{
    // Success handling
}

Synchronize Equipment Data

var equipmentId = Guid.NewGuid();
var alarms = GetEquipmentAlarms(equipmentId);
var result = await beijingYounuoService.SynchronizeEquipmentAlarmsAsync(equipmentId, alarms);

Correlate Digital Twin Data

var apiData = await beijingYounuoService.GetDigitalTwinDataAsync();
var correlatedData = await beijingYounuoService.CorrelateDigitalTwinDataAsync(apiData.Data);

Next Steps

1. Test the enhanced methods with actual Beijing Younuo API endpoints
2. Implement additional business rules based on specific requirements
3. Add unit tests for the new business methods
4. Consider adding caching for frequently accessed data
5. Implement batch processing for large data sets

Notes

• All existing methods remain unchanged to maintain backward compatibility
• New methods are clearly marked in the "业务导向的增强方法" region
• The enhancement follows SOMS coding standards and patterns
• Proper dependency injection and configuration management maintained
