What this category of data looks like
This category of data typically comes from highway maintenance management systems, bridge and tunnel monitoring systems, road patrol systems, and traffic flow monitoring data, with a daily update frequency. Daily involved documents include maintenance plans, patrol logs, defect handling orders, road construction permits, and road property damage compensation forms. Each document contains fields such as facility ID, location coordinates, defect type, and handling time limit. Some documents are accompanied by binary-format on-site photos or monitoring waveform data.
What constraints these characteristics impose on the "workflow orchestration" link
This category of data spans multiple independent systems and updates daily, requiring workflows to be configured with cross-system data pull nodes and scheduled triggers. The field structures of different documents vary significantly, so dynamic parameters must be defined via variables to adapt to field mappings for different documents. The workflow includes multiple serial links such as patrol, handling, acceptance, and compensation, so dependency trigger rules between nodes must be configured to ensure the next task starts only after the previous link is completed. Some links involve on-site data collection, requiring support for offline data retransmission and automatic synchronization to the workflow to avoid process interruptions.
Configuration guidelines
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Scheduled trigger cycle | 1440 minutes | Core data of this category updates daily, requiring synchronization of the latest maintenance and patrol data on a natural day basis |
variables | Facility ID, Defect Type, Handling Priority | Needs to dynamically adapt to the fields of different maintenance documents and flexibly pass task parameters across nodes |
| Node dependency trigger | Trigger based on upstream node completion status | Strict serial order exists in links such as patrol, defect handling, and acceptance, requiring the next task to start only after the previous link’s data is submitted |
| Failure retry count | 2–3 times | Cross-system data pulls may fail due to network fluctuations; limited retries can reduce the probability of process interruptions |
| File upload size limit | 1000 MB | Maintenance documents often include on-site photos and monitoring waveform files, requiring adaptation to large-volume attachment data |
nodeId | Fill in according to the actual node number | Needs to accurately locate the trigger rules of specific nodes to avoid configuration conflicts in multi-node workflows |
Three common misconfigurations
- Symptom: The workflow file upload link prompts
Failed to create post presigned url, and file submission cannot be completed. Cause: Object storage keys and bucket permissions are not configured correctly, or storage configuration parameters were not synchronized and updated after a version upgrade. - Symptom: Parameter transfer between workflow nodes is empty, and the fields of maintenance documents cannot be mapped correctly. Cause: Mapping rules for corresponding fields are not defined in
variables, or the correct variable source was not selected during node configuration. - Symptom: Scheduled trigger workflows do not execute on time, resulting in data synchronization delays. Cause: The scheduled trigger cycle is set to a non-natural day cycle, or the system time zone configuration does not match the business time zone.
How to confirm proper configuration
- Manually trigger the workflow once, check whether cross-system data pull is successful and whether the fields of the corresponding documents are correctly mapped to
variables. - Upload a simulated maintenance-related document to confirm that the file upload link has no errors and attachments can be stored normally.
- Adjust the scheduled trigger cycle configuration to verify whether the workflow starts according to the new cycle.
- Simulate a scenario where the upstream node is not completed, confirm that the downstream node will not trigger automatically.
