What this category of data looks like
This category uses the following data sources: customer color samples, formula libraries, dye chemical batch records, dye vat control equipment, colorimeters, setting machines, and environmental monitoring systems. Daily generated documents include dyeing formulas, material weighing and preparation records, dye vat curves, proofing confirmation sheets, color difference reports, setting process sheets, and sewage ledgers. Data updates occur per vat, per batch, or per shift. Fields include dye vat temperature (℃), feeding amount (kg), color difference value ΔE, discharge concentration (mg/L), and others. Single-vat process data uses unique vat number and batch number identifiers. Field dimensions cover three categories: process parameters, quality inspection, and environmental compliance.
Constraints on workflow orchestration
This category’s process data updates dynamically per vat or batch. Workflows must pull the latest batch-associated data on each trigger to avoid using expired dye chemical parameters or historical process records. Dispersed storage of multiple document types requires workflows to split into multiple retrieval nodes, which call independent data sources such as dyeing formulas, dye vat curves, and environmental ledgers separately. A single-vat process error can cause full vat scrap, non-compliant color matching with order requirements, or environmental over-standard discharge. Therefore, workflows must add parameter verification and log tracing links, and support precise data matching by vat number or batch number to prevent cross-batch data confusion. Additionally, color judgment for wet chemical processing relies on real-time test results, so workflows must prioritize measured data such as colorimeters and proofing records, rather than relying solely on static formulas.
Configuration settings
These configuration instructions apply to FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
variables | Bind vat number, batch number, and color sample number | Precisely match single-vat process data, avoid cross-batch confusion, and ensure Q&A content aligns with current processing tasks |
| Parallel conversation node triggering | Call dyeing formula, dye vat curve, and color difference report nodes in parallel grouped by vat number | Multiple process documents for a single vat can be retrieved independently; parallel execution improves workflow response speed |
nodeId | Use vat number and batch number as log identifiers | Locate specific single-vat process queries, facilitating subsequent troubleshooting and log tracing |
| Query merging module | Merge dyeing parameters and color difference data from the same batch, filter documents from unrelated batches | Integrate scattered process documents into a unified context to ensure completeness and accuracy of Q&A content |
| Timeout threshold | 120 seconds | Retrieval of dye vat process data requires calls to multiple device interfaces and document libraries; reserve sufficient response time |
| Context length | 8000–12000 characters | Total length of single-vat process documents is large; sufficient context ensures responses cover all key process parameters |
| Maximum number of retrieved entries | Top 10 entries | The number of process documents per single vat is limited; excessive retrieval results will cause context redundancy and reduce response efficiency |
Three common errors
- Phenomenon: The process data returned in the conversation does not match the current vat number, and dyeing formulas or color difference reports from other batches appear. Cause: The
variablesbinding of unique identifiers such as vat number and batch number was not performed, causing the workflow to call data from historical batches. - Phenomenon: Workflow node execution times out, and the interface displays "request timeout" error. Cause: No reasonable timeout threshold was set, or parallel retrieval nodes were not split, causing a single node to load excessive cross-document process data.
- Phenomenon: The query merging module returns an insufficient number of results, failing to cover all process information for the current vat. Cause: Retrieval results were not filtered by batch number, and irrelevant data from other vats was mixed in, causing valid results to be truncated.
How to confirm correct configuration
- Initiate a single-vat process query, check whether the returned process data matches the dyeing formula, dye vat curve, and color difference report for the current vat number.
- View the workflow's conversation logs, confirm that each log is bound with
nodeIdand vat number identifiers, and can directly locate the specific query task. - Trigger a parallel node task, check whether multiple process document retrieval nodes are called simultaneously, with no serial waiting.
- Enter an abnormal batch number or vat number, check whether the workflow triggers parameter verification and returns clear prompt information.
The configuration values provided here are common starting points, and should be evaluated against applicable on-site samples.
