What This Category's Data Looks Like
Manufacturers of pumps, valves, compressors, reducers, machine tools, and custom non-standard equipment use this data. Daily documents include assembly process cards, BOMs, torque records, clearance adjustment records, commissioning reports, factory inspection sheets, and packing lists. Data sources include PLM/ERP systems, part inspection data, assembly tool collection data, test bench data, MES systems, and customer technical agreements. Updates occur per single device or per order. Most document structures include hierarchical BOMs and assembly parameters with specific values. The core difference from part machining categories is that this category uses multi-variant order-based assembly, and final performance depends on component fit and on-site commissioning, rather than focusing primarily on single-dimensional dimensional compliance.
Constraints on Citation Sources and Traceability
The multi-variant order-based assembly model mandates that traceability information links to order numbers and device serial numbers, preventing document mixing across orders. The combination of multi-level BOMs and multi-source data requires the traceability system to accurately associate documents from different systems, ensuring cited content originates from the correct assembly stage. High-frequency per-device updates require the indexing mechanism to support near-real-time synchronization, ensuring cited content uses the latest assembly and inspection records. Document content with specific parameters requires retaining field and unit information during traceability, to help verify consistency between physical objects and recorded data.
How to Configure Settings
| Config Item | Recommended Value | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Adapts to the paragraph structure of documents such as assembly process cards and BOMs, avoiding splitting critical hierarchical information |
| Overlap Length | 150–200 characters | Retains the associated context of BOM parent and child parts, preventing loss of hierarchical relationships across chunks |
| Single Search Limit | Top 8 entries | Covers multiple types of documents involved in single-device assembly, avoiding omission of key inspection records |
quoteMaxToken | 3000 token | Accommodates complete cited content of assembly parameters such as torque and clearance, ensuring traceability information is not truncated |
responseData | Enabled | Outputs document type, update time, and associated order number of cited sources, meeting metadata requirements for audit traceability |
detail | Enabled | Displays original fragments of cited content, facilitating direct verification of consistency between physical objects and records |
Three Common Mistakes
- Phenomenon: Corresponding order torque records are not returned in search results. Cause: The data source associated with the MES system is not configured, only static BOM data in PLM is indexed, and real-time assembly collection information cannot be obtained.
- Phenomenon: Console error Cannot redefine property: toString appears. Cause: The system's built-in prototype method is incorrectly modified when configuring
responseData, causing initialization conflicts. - Phenomenon: Specific units are not displayed in cited clearance adjustment records. Cause: Chunk length is set too small, truncating parameter fields containing units and losing critical verification information.
How to Confirm Proper Configuration
- Initiate a query targeting the assembly process of a single device, check whether the returned results include source identifiers and associated order numbers of corresponding documents.
- View the original content of cited fragments, confirm whether parameter fields unique to this category such as torque and clearance, along with their corresponding units, are included.
- Test retrieval of multi-order data, confirm that documents from different orders are not mistakenly cited together.
- Check the FastGPT v4.17.0 system log, confirm that no error messages about prototype method redefinition appear.
