Drafting of Process Documents and Exception Reports for Precast Concrete Components: Workflow Orchestration

This category of data comes from BIM detailed design documents, steel bar and concrete batch ledgers, mold table and curing kiln operation logs

What data for this category looks like

This category of data comes from BIM detailed design documents, steel bar and concrete batch ledgers, mold table and curing kiln operation logs, laboratory test reports, and component QR code traceability systems. Daily generated documents include component detailed drawings, steel bar cutting lists, mold inspection records, pouring and vibration records, curing records, and demolding and factory inspection reports. Data updates are triggered by individual components, each batch of materials, or each curing kiln process. Document fields include component number, steel bar specification, pouring strength, curing duration, test results, and more. Units include millimeters, megapascals, hours, batch numbers, and more.

Because data sources are scattered and update triggers vary, the workflow must support pulling and triggering from multiple sources to avoid missing updates for individual components, batches, or curing kilns. Component detailed drawings must be split into component and embedded parts lists. The workflow must configure split nodes that match disassembly rules for different component types. Verification of steel bars, sleeves, and embedded positions must link multi-dimensional data. The workflow must include cross-document field verification steps. Exception reports must link traceability data. The workflow must bind QR code traceability information to ensure one-to-one correspondence between exception records and corresponding components, preventing scrap or schedule delays caused by misalignment, insufficient strength, and other issues.

How to set up configurations

This configuration is based on FastGPT v4.17.0.

Configuration ItemRecommended ApproachRationale
variablesBind component number, steel bar batch number, curing kiln IDMatch the update rhythm of this category by individual component, batch, or curing kiln, and link scattered multi-source data
nodeIdBind detailed drawing split node, data verification node, report generation nodeClarify execution order and dependency relationships for each link to avoid process chaos
File upload node timeout600 secondsAdapt to upload durations for large component detailed drawings and batch test records
Single file upload limit1000 MBAdapt to storage requirements for large BIM detailed design drawings
Context window size800–1200 tokenAdapt to the concatenated length of single test reports and traceability data
Knowledge base bindingPrecast concrete component process knowledge baseCover exclusive documents including detailed drawing disassembly, process standards, and inspection specifications

Three common errors

  • A "Failed to create post presigned url" error appears when uploading files via the workflow. This happens because the correct object storage key and permissions are not configured, or the node timeout setting is too short, causing the upload to be interrupted.
  • Variable references in the knowledge base search module are not correctly bound to component numbers, leading search results to match incorrect process documents. This happens because the component number field in variables is not linked to the search parameters.
  • The workflow is not configured with a cross-document verification node, leading to inconsistent embedded part positions between the steel bar cutting list and detailed drawings, which causes subsequent production abnormalities. This happens because a cross-source data verification step is not included.

How to confirm the configuration is complete

  • Trigger the production node for a single component, check whether the workflow automatically pulls the corresponding detailed drawing, cutting list, and test records.
  • Simulate uploading a large component file, confirm that the file upload node completes within 600 seconds without errors.
  • Adjust the component number in variables, check whether knowledge base search results update as the number changes.
  • View workflow logs, confirm that each link corresponding to nodeId executes in the preset order, with no skips or repetitions.
