Cross-Review of Technical Documentation for Photovoltaic Module Encapsulation: Workflow Orchestration

Photovoltaic module encapsulation process data covers multiple types of documents from string welding, lamination, framing, and testing departments.

What Data for This Category Looks Like

Photovoltaic module encapsulation process data covers multiple types of documents from string welding, lamination, framing, and testing departments. These include layout drawings, material batch records, lamination process records, EL images, IV test reports, insulation voltage withstand records, and packing lists. Data sources include cell grading data, glass adhesive film backplane batch information, factory MES systems, string welding and lamination device logs, and EL/IV tester output results. Data update frequency follows two patterns: one exclusive document is generated per module, and batch dimension records are updated synchronously for each batch of materials. Fields include professional parameters such as current gear, power value, and crack coordinate. Units include watts, volts, millimeters, and other standard units.

Constraints Imposed on Workflow Orchestration by These Characteristics

Data for this category is scattered across multiple systems and devices. Workflows must support batch pulling and integration across data sources. The real-time update feature requires workflows to use trigger-based execution. This matches the immediate update rhythm of each module and batch of materials. Multiple document types require workflows to support parsing rules for different formats. This covers extraction of both chart and text content. Requirements for professional fields and units mean workflows must include extraction rules for corresponding parameters. This prevents data confusion across different batches and modules.

How to Configure the Workflow

The following configurations are formulated based on the workflow orchestration rules of FastGPT v4.17.0.

Configuration ItemRecommended SettingRationale for This Setting
Data Source Association ConfigurationBind API interfaces of MES systems, EL testers, and lamination devicesMatches the scattered multi-source data sources of this category
Variable Extraction RuleExtract fields including batch number, power value, and crack coordinate from variablesAdapts to professional data fields and business requirements of photovoltaic module encapsulation
Node Trigger ConditionTrigger based on the timestamp of device-reported dataMatches the real-time update frequency of each module and batch of materials
Exception Retry Count3 times, with a 60-second intervalAddresses temporary network fluctuations and data delays in device reporting
Context Window Size800–1200 charactersAdapts to the average data length of documents corresponding to a single module
Node ID ConfigurationMark business links such as string welding, lamination, and testing with nodeIdClarifies the business attribution of each node in the workflow

Three Common Configuration Mistakes

  • An uncaught exception pops up during workflow runtime, with logs indicating an incorrect configuration file. The cause is that the API key and access permissions of the data source were not correctly configured during private deployment.
  • Workflow nodes cannot select preset professional AI models, only displaying simple model options. The cause is that the model call permission for the corresponding business scenario was not enabled in the configuration, resulting in failure to load model options.
  • Workflow execution times out, returning a request timeout status code. The cause is that reasonable retry intervals and counts were not set, so automatic retries were not triggered when device-reported data is delayed.

How to Verify Successful Configuration

  • Manually trigger a test data set from the string welding link, and check whether the workflow automatically pulls corresponding batch material records and EL images.
  • View the workflow’s node logs to confirm that fields including cell current gear and power value extracted from variables are complete and meet preset unit requirements.
  • Simulate temporary network fluctuations during device reporting, and check whether the workflow automatically initiates retries according to the configured retry rules.
  • Check whether the nodeId markers of each link correspond one-to-one with business nodes of departments such as string welding, lamination, and testing.
