Drafting of Process Documents and Exception Reports for Precast Concrete Components: Deployment and Upgrade

What the data for this category looks like

Precast concrete component factories generate core data from BIM detailed design, rebar and concrete batch ledgers, mold table and curing kiln operation logs, laboratory test reports, and QR code traceability systems. Daily documents include component detailed drawings, rebar cutting lists, mold inspection records, pouring and vibration logs, curing cycle records, demolding and factory inspection reports.

Data update frequency is adjusted to match production rhythm. Independent data is created for individual components, each batch of rebar and concrete, and each curing batch in a kiln. Data fields include component number, embedded part position parameters, strength test values, production team information, and other relevant details. Units include millimeters, megapascals, cubic meters, and other common engineering units.

Unlike other construction products, data for this category must be bound one-to-one with on-site lifting positions. Bulk fluid delivery is not supported for this category.

What constraints these characteristics impose on deployment and upgrade

Multi-source heterogeneous data sources require adaptation to different document and ledger formats during deployment, to avoid data silos. High-frequency, individual and batch-level updates require the system to support real-time or near-real-time data synchronization. This creates demands for concurrent performance in storage and indexing.

Complex document structures and precise field matching needs mean targeted document parsing rules must be configured during deployment. This ensures key information such as embedded part positions and strength parameters is accurately extracted.

Data association rigor directly impacts production quality. Multiple layers of validation logic must be added during deployment, to prevent erroneous data from entering the drafting process.

How to configure settings

This configuration is based on FastGPT v4.17.0.

Three common misconfigurations

• The symptom is that process document tables are truncated when displayed on the frontend, with ...[hide 38432 char shown at the end. The cause is that no reasonable document context length limit is configured, causing long table content to be automatically truncated.
• The symptom is that matching results between rebar cutting lists and component detailed drawings are empty. The cause is that MONGODB_URI is not correctly configured to point to the component metadata database, causing the data association logic to fail.
• The symptom is that synchronization delay for curing records exceeds production rhythm requirements. The cause is that DB_MAX_LINK is set too low, failing to support concurrent data writes when multiple kilns operate simultaneously.

How to verify a successful configuration

• Upload a precast component detailed drawing and its corresponding rebar cutting list. Check whether the system can accurately extract key information such as component number and embedded part positions. Verify that the extracted results match the source documents.
• Simulate a pouring and vibration abnormality scenario, and launch an exception report drafting test. Check whether the system can automatically associate corresponding batch mold table, curing kiln, and laboratory test data.
• View system operation logs. Confirm that the connection status of REDIS_URL and MONGODB_URI is normal, with no frequent connection errors.
• Organize multiple engineers to simultaneously access the system to launch drafting tasks. Check whether the DB_MAX_LINK configuration can support concurrent requests, with no connection timeouts.
