What the Data for This Category Looks Like
Telecommunications engineering construction business data is primarily sourced from official documents including project approval ledgers, site survey records, construction permit documents, and acceptance filing reports from telecommunications operators. Data update frequency is adjusted in real time alongside project progress: construction node information is synchronized after project approval, and archived and locked once acceptance is completed. The document structure uses the unique project number as the core index, including fields such as construction location, material specifications, approval nodes, and acceptance standards. Units include engineering-specific units such as meters, kilowatts, pieces, and workdays. A complete single project document typically ranges from several thousand characters in length.
How These Characteristics Constrain Multi-turn Dialogue and Prompt Engineering
Telecommunications engineering construction data uses the unique project number as the core index and is updated in real time alongside project progress. This requires multi-turn dialogue to precisely match this number to locate corresponding approval information and avoid mixing up different project contents. Documents contain a large number of engineering-specific fields and units, so prompts must clearly guide users to provide necessary project identifiers to narrow the large model’s retrieval scope. Additionally, multi-turn dialogue must retain historical approval node information to avoid repeated inquiries about basic construction parameters and ensure session coherence. The coexistence of structured ledgers and unstructured survey documents requires prompts to distinguish calls to different data sources to improve guidance accuracy.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Maximum Context Length | 8000–12000 token | Telecommunications engineering approval documents contain multi-node approval opinions; overly long contexts will dilute core process information. This range is calibrated based on actual testing. |
| Custom Variable Binding | Bind variables for project number and construction material specifications | Telecommunications engineering data fields are specialized and dispersed. Directly calling structured ledgers via variables reduces the large model’s understanding cost. |
chatId Configuration | Bind the unique project identifier | Ensures context association across multi-turn dialogue for the same project, avoiding cross-project information confusion. |
| Historical Dialogue Retention Count | Retain the most recent 20 rounds of messages | Telecommunications engineering approval processes have multiple nodes; retaining historical dialogue avoids repeated inquiries about basic information. |
| Prompt Template | Fixed to include "Please provide the project number to obtain the corresponding approval process" | Telecommunications engineering projects are unique; quickly locating data via the project number reduces invalid user input. |
| Multi-turn Session Timeout | 600 seconds | Engineering approval processes involve cross-departmental reviews, so sufficient time must be reserved for information synchronization. |
| Single Upload File Limit | 1000 MB | Files such as engineering survey drawings have large sizes; this setting follows general engineering file storage standards. |
Three Common Misconfigurations
- Phenomenon: Repeated inquiries about the same basic engineering information appear in multi-turn dialogue. Cause:
chatIdis not correctly bound, resulting in independent session contexts each time, so historical input cannot be retained. - Phenomenon: AI dialogue node output content is directly mixed into the business process guidance return results. Cause: No output filtering rules are configured for the node, causing debug logs to be included in formal responses, which corresponds to the common community issue of residual debug output.
- Phenomenon: The session cannot obtain approval process information for a specified project. Cause: The project number variable is not bound via
variables, so the large model cannot accurately locate the corresponding project data.
How to Confirm Proper Configuration
- Initiate a test session, input any engineering-related question, and verify whether the returned content includes the bound custom variable fields to confirm normal variable calling.
- Initiate two consecutive sessions using the same project number, and verify whether the session retains historical dialogue information to confirm correct
chatIdconfiguration. - Upload engineering-related files, and verify whether the AI can parse the file content and associate it with the business process to confirm normal file upload function configuration.
- Simulate multi-round approval node inquiries, and verify whether the AI only returns content related to the engineering business process to confirm that the prompt constraint takes effect.
