What this category’s data looks like

Core users are process, equipment, quality, and production departments at crystalline silicon cell manufacturing enterprises. Daily documents include process cards, diffusion and coating parameters, printing and sintering records, EL inspection images, IV grading data, and yield reports. Data sources cover incoming silicon wafers, MES systems, production equipment such as diffusion furnaces, coating equipment, and printing presses, EL and IV testing equipment, and laboratory test data. Three update frequency levels apply: per batch, per wafer inspection, and daily. Core work includes controlling process windows for texturing, diffusion, passivation, and electrode processes, identifying hidden cracks, color differences, and efficiency losses, and tracing via electrical performance grading.

Constraints Imposed on Tool Calling and Plugins Workflow

Scattered data sources and uneven update frequencies require tool calling to support real-time pulling and association of multi-source data. This prevents data gaps from reducing the accuracy of inspection results. Coexistence of multiple document types requires plugins to adapt to both structured parameter queries and unstructured image and text parsing. This covers scenarios such as process parameter verification and defect identification. High-frequency wafer-level data and process window control requirements require tool calling to accurately match the current device’s context information. This avoids interference from redundant data during judgment.

Configuration Settings

Configuration ItemRecommended SettingRationale
Workflow/API tool selectionauto or a designated device parameter query toolAdapts to the precise calling needs of equipment inspection, and prevents the model from calling irrelevant tools
Workflow/API function-call configurationEnabledSupports triggering preset tools such as parameter verification and log extraction, matching the scenario needs of photovoltaic equipment maintenance
Maximum context length8000–12000 tokenAccommodates process cards, text descriptions of EL inspection images, and IV grading data for a single batch, preventing truncation of critical information
Single tool call timeout300 secondsAdapts to time-consuming scenarios such as EL inspection image analysis and device log pulling, calibrated via actual testing
Number of recalled resultsTop 3–5 entriesFocuses on historical inspection records and process parameters for the current device, avoiding interference from redundant information
FastGPT Versionv4.17.0Adapts to the latest tool calling and plugin management logic, ensuring functional stability

Three Common Misconfigurations

  • When calling a large model that only supports stream mode, logs such as "data acquisition exception" or "error" are returned. This occurs because stream mode adaptation is not enabled in the model channel configuration, causing incompatibility between synchronous calls and the model interface.
  • A configuration conflict error occurs when upgrading the PgVector plugin. This happens because the index task for the associated knowledge base is not paused before upgrading, leading to file occupation and data synchronization conflicts.
  • The text extraction tool returns the 400 Invalid JSON payload received. Unknown name error. This occurs because the incoming text description of EL inspection images or device logs contains unescaped special characters, which do not meet JSON format requirements.

How to Verify Successful Configuration

  • Initiate a query related to equipment inspection, and check whether preset parameter query and log extraction tools are correctly triggered in the tool calling logs.
  • Test calling a large model that only supports stream mode, and confirm that the streaming results have no interruptions and no data exception errors.
  • Trigger the text extraction tool, and check whether the returned results use valid JSON format, with no unknown field errors.
  • View the version information of the PgVector plugin, confirm that it has been upgraded to the target version, and that the associated knowledge base index task is running normally.
