What data for this category looks like
Data sources for this category include the road transport administration system, the national public service platform for dynamic information of road transport vehicles, and the vehicle and practitioner database. The update frequency is daily. Daily processed documents include business license applications, vehicle technical files, driver qualification materials, work safety management systems, and road transport business licenses. Data fields cover vehicle license plates, qualification certificate numbers, licensed business scopes, site inspection information, and more. Data is stored by application batch and license validity status, with no additional custom extended fields.
What constraints these characteristics impose on workflow orchestration
Daily updated data requires setting a fixed periodic trigger for the knowledge base sync node in the workflow, to avoid data lag affecting answer accuracy. Multi-data-source docking requirements mean configuring cross-system data pull nodes in the workflow, and passing interface authentication parameters from different systems via variables. The presence of multiple types of business documents requires setting up a document classification recognition node in the workflow to match corresponding question and answer templates. The time-consuming links of verifying vehicles, personnel and safety systems require splitting this link into independent judgment nodes and setting a timeout retry mechanism to avoid overall process blocking.
How to set configurations
| Configuration Item | Recommended Practice | Rationale |
|---|---|---|
| Global variable configuration | Define grouped by data source type, include authentication parameters, query thresholds | Adapt to multi-system docking needs, simplify cross-node parameter transfer |
| Node ID binding | Configure unique nodeId for core nodes such as database queries, answer generation | Ensure correct data flow path, avoid node call confusion |
| Knowledge base sync trigger | Perform full sync at 2 AM daily | Match daily data update frequency, ensure answer data timeliness |
| Single query limit | Top 10 entries | Adapt to single query scale of business data, avoid returning redundant content |
| Interface call timeout | 600 seconds | Adapt to time-consuming needs of cross-system data pulling, avoid process interruption |
| External parameter passing | Declare receivable variables fields in the workflow | Support external platforms passing real-time business parameters, adapt to dynamic question and answer scenarios |

Three common misconfigurations
- Phenomenon: After the workflow runs, the answer does not include vehicle or personnel data queried from the database, and only returns general policy statements. Cause: The output of the database query node is not bound to the context parameters of the answer generation node.
- Phenomenon: The judgment node always returns a non-empty judgment result regardless of input content. Cause: The trigger condition of the judgment is not correctly bound to the input field, and a global constant is mistakenly used as the judgment basis.
- Phenomenon: When calling the published interface from an external platform, the passed business parameters are not received by the workflow, and a parameter missing error is returned. Cause: The external incoming fields that need to be received are not declared in the workflow's
variablesconfiguration, and the parameter transfer path corresponding to the configurednodeIdis not correctly set.
How to confirm the configuration is correct
- Manually trigger the workflow, pass preset business parameters, check if
variablesparameters are correctly loaded into the process nodes. - View the knowledge base sync logs, confirm that the daily sync task runs normally during the specified period with no failed records.
- Simulate database query operations, verify that the answer generation node references valid data returned from the query.
- Configure judgment node test cases, input different types of business data, confirm that the judgment results meet expectations.
