What this category’s data looks like

This category covers documents and real-time sensor data related to the full equipment lifecycle. Documents include equipment ledgers, inspection checklists, maintenance plans, work orders, fault analysis, spare parts lists, and special equipment inspection records. Data sources include EAM/CMMS systems, device sensor data, operator inspection records, maintenance history databases, spare parts inventory systems, and statutory inspection information. Update frequency varies by scenario: inspection data is updated per shift, maintenance plans are updated weekly or monthly, and fault information is synchronized immediately when a fault occurs. Data fields include unique equipment numbers, inspection item descriptions, fault levels, spare part codes, inspection validity periods, and additional relevant fields. There are no unified fixed units; actual measurement requirements are matched based on individual field attributes.

What constraints these characteristics impose on HTTP interfaces and external systems

Dispersed data sources and widely varying update frequencies for equipment inspection and preventive maintenance require HTTP interfaces to support batch pulling and incremental synchronization of multi-source data. Significant differences in field structures across different documents mean interfaces must support dynamic field mapping, and avoid hard-coded field matching rules. Immediate data synchronization requirements for fault occurrences require reasonable timeout settings for interfaces. The statutory nature of special equipment inspection records requires that interface-transmitted data cannot be tampered with, and request legitimacy must be verified via the Authorization parameter. Real-time requirements for spare parts inventory data require interfaces to support high-frequency calls, and request rate limits must be configured appropriately.

How to set configurations

Configuration ItemRecommended ApproachRationale
AuthorizationCarry a Bearer token issued by the internal enterprise systemUsed to verify the legitimacy of external system requests, and meets the secure transmission requirements for equipment data
Request timeout600 secondsAdapts to the time required for pulling device sensor data and synchronizing large work orders
variablesBind business variables such as equipment numbers and inspection cyclesEnables pulling targeted inspection data for specific equipment, and avoids pulling redundant full-volume data
responseDataOnly return core fields of equipment ledgers, inspection records, and fault reportsFilters irrelevant data and reduces interface transmission load
Single request data limitFirst 500 entriesMatches the batch pulling scale of shift-by-shift inspection data, and avoids interface overload
Data update trigger ruleSynchronize based on data change timestampsAdapts to incremental update requirements for multi-source data, and reduces invalid requests

Three common mistakes

  • Symptom: The interface returns a 401 Unauthorized status code, and equipment data cannot be pulled. Cause: The Authorization parameter is not configured correctly, and a valid system access token is not carried.
  • Symptom: The responseData returned by the interface contains a large number of redundant fields, leading to system processing timeouts. Cause: The range of returned fields is not limited, and valid data is not filtered based on core equipment inspection and maintenance documents.
  • Symptom: Partial fields are empty when pulling inspection data in batches, and the data cannot match the format of the local system. Cause: The device number variable is not bound via variables, and data is not pulled for the specified equipment dimensions, leading to mismatched field mappings.

How to confirm the configuration is complete

  • Use the HTTP interface tool in FastGPT v4.17.0 to send a test request, and check that the returned responseData only includes core fields such as equipment ledgers, inspection records, and fault reports, with no redundant data.
  • Send a request with a valid Authorization token, and confirm that the returned status code is 200 OK, with no permission-related errors.
  • Send a request with a bound equipment number variable, and confirm that the returned data only includes inspection and maintenance information for the corresponding equipment, and fields match the format of the local system.
  • Simulate an immediate request when a fault occurs, and confirm that the interface can normally receive and process the request, return the corresponding fault report data, and the synchronization delay meets the business-set thresholds.
