What the Data for This Category Looks Like
Data for this category originates from internal property management systems, real estate registration and filing documents, and on-site inspection records. Daily inspection records update in real time. Work order summaries update weekly. Property fee statistics and special maintenance fund ledgers update monthly.
Documents include structured ledgers (Excel/CSV format) and unstructured attachments (inspection photos, work order PDFs, fund transaction vouchers). Structured fields include project name, number of managed households, number of individual buildings, total public energy consumption amount. Units for these fields are respectively: none, households, buildings, kilowatt-hours. The unit for property fee unit price is yuan/square meter·month.
Constraints Imposed on Workflow Orchestration
The mixed structured and unstructured data source structure requires workflows to support both structured field extraction and multimodal file parsing. Workflows cannot rely solely on default text parsing nodes.
Data sources with varying update frequencies require workflows to use a combination of scheduled trigger and manual trigger nodes. This adapts to the different update rhythms of real-time inspections, weekly summaries, and monthly ledgers.
Structured data with multiple fields requires workflows to include precise field mapping nodes. This avoids missing extracted fields or incorrect unit matching.
Data access from multiple sources requires workflows to reserve multiple data source docking nodes. This adapts to different access methods for internal management systems, filing documents, and on-site records.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
ENABLE_DIRECT_FILE_PASS | Enabled | Adapts to direct parsing of multimodal attachments such as property inspection photos and work order PDFs. Prevents loss of image and format information from default text parsing. |
CODE_NODE_MAX_COUNT | 8 | Supports simultaneous configuration of multiple code nodes. These nodes handle property data across dimensions including property fee calculation, energy consumption statistics, and work order summary. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to parsing durations for large special maintenance fund transaction PDFs and multi-page inspection reports. Prevents task interruption due to timeout. |
CHUNK_SIZE | 800–1200 characters | Adapts to segment lengths for property structured ledgers and unstructured text. Prevents large model field extraction deviations caused by overly long paragraphs. |
MODEL_ENV_VAR_ENABLE | Enabled | Supports configuration of dedicated due diligence models via environment variables. Adapts to personalized prompt requirements for different property projects. |
PROMPT_SPACE_HANDLER | Enabled | Adapts to field names and units containing spaces in property data. Prevents extraction errors caused by prompts failing to recognize spaces. |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: Uploaded inspection photos cannot be directly understood by the large model. Returned results only contain text descriptions, with no image information. Cause: The
ENABLE_DIRECT_FILE_PASSconfiguration is not enabled, and the default text parsing node is used to process multimodal files. - Symptom: The workflow runs with the error
CODE_NODE_LIMIT_EXCEEDED, prompting that the number of code nodes exceeds the upper limit. Cause: TheCODE_NODE_MAX_COUNTconfiguration is not adjusted, and the default value is insufficient to support multiple property data processing nodes. - Symptom: The prompt fails to recognize space-separated fields in property data, leading to misaligned extracted field values. Cause: The
PROMPT_SPACE_HANDLERconfiguration is not enabled, and the prompt does not adapt to space recognition rules.
How to Confirm Configuration is Correctly Set
- Upload a single inspection photo to the workflow node. Check whether the large model output includes image content descriptions to confirm the multimodal file parsing configuration takes effect.
- Add multiple code nodes and run the workflow. Confirm that the code node quantity limit error is not triggered, and that the code node quantity configuration meets requirements.
- Edit the due diligence prompt, enter a field name containing spaces. Check whether the field extraction results are accurate to confirm the space recognition configuration takes effect.
- Check the scheduled trigger settings of the workflow. Confirm that trigger rules corresponding to different update frequencies have been configured, to adapt to the real-time, weekly, and monthly update rhythms of property data.
