What the data for this category looks like
It typically includes daily documents such as maintenance plans, patrol logs, defect disposal orders, road construction permits, and road property damage compensation forms. Data comes from highway maintenance management systems, bridge and tunnel monitoring systems, road administration patrol systems, and traffic flow monitoring data, with an update frequency of once per day. Documents usually contain fields including facility ID, defect type, disposal time limit, construction scope, and compensation amount. Units include kilometers, square meters, working days, and other relevant units. Document formats exported by different systems have certain differences.
What constraints these characteristics impose on the multi-turn dialogue and prompt engineering link
Multi-source documents updated daily require associating dialogue context with historical work orders and disposal records to ensure case review continuity. Differences in document formats and fields exported by different systems require prompts to adapt to various non-standard content. Case files for road construction and road property damage need to trace historical compliance records, so multi-turn dialogue must retain complete interactive context. Rules for different review links must be passed via unified parameters to avoid logical inconsistencies caused by repeated configuration.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chatId binding rule | Bind to a single review task | Ensure that the dialogue context for the same case review is not confused with other tasks, complying with the session isolation requirements of FastGPT v4.17.0 |
messages context retention limit | First 20 rounds of dialogue content | Adapt to the requirement of reviewing cases that need to trace multi-day patrol and disposal records, avoiding performance loss caused by overly long context |
variables passed parameters | Maintenance standards, review thresholds | Uniformly adapt to the field rules of different documents, reducing repeated definition of prompts and configuration errors |
| Maximum response waiting time | 600 seconds | Reserve sufficient time for multi-source data recall and case verification, adapting to the time-consuming requirements of daily review |
| Question optimization switch | Enabled | Simplify the expression of professional maintenance terminology, improving the accuracy and readability of review instructions |
Three Common Configuration Mistakes
- A 500 error is returned when importing road construction permit documents. Cause: The non-standard construction scope field included in the document is not adapted, and unified field mapping rules are not passed via
variables. - All historical dialogue results are output after multiple AI dialogue modules are executed in a workflow. Cause: The
chatIdbinding rule for a single review task is not configured, causing historical dialogue context to be reused across tasks. - Response delay exceeds 3 seconds when initiating a case review dialogue for the first time. Cause: No preheating loading strategy for dialogue context is configured, and all historical data must be loaded during the first request, resulting in excessively long waiting time.
How to Verify Successful Configuration
- Upload a maintenance patrol log document, and check whether core fields such as facility ID and defect type can be parsed and extracted normally.
- Initiate two consecutive case review dialogues, and check whether the second dialogue responds only based on the context of the current task, without calling irrelevant historical content.
- Wait for the first dialogue to initiate, and check whether the response delay meets the preset maximum response waiting time requirement, and whether the response speed of subsequent dialogues is stable.
- Configure
variablesto pass review rules, and check whether the dialogue process uniformly follows the preset maintenance standards for verification.
