What the data for this category looks like
Data related to consulting and response for telecommunications engineering construction comes primarily from project approval documents, construction logs, acceptance reports, industry standard documents for projects such as communication base station construction and line laying, correspondence from service windows, and common question logs for public inquiries. Document update frequency aligns with project progress. Content such as construction details and budget adjustments is added irregularly during a single project cycle. Industry standard documents are updated quarterly. Document types include long-text PDFs, dense table Excel files, and structured Word documents. Fields include project numbers, base station locations, frequency band parameters, material models, budget amounts, and more. Units use professional measurement standards such as meters, watts, megabytes, yuan, days, and other relevant units.
Constraints Imposed on Document Parsing and Chunking
The characteristics of telecommunications engineering documents create multiple constraints for the parsing and chunking workflow. Long-text PDFs contain continuous construction process descriptions. If chunk length is too short, construction logic is disrupted. If chunk length is too long, context association is lost. The cell association relationships in dense table documents are easily broken by default parsing logic, leading to missing data fields. Structured service guide documents have clear chapter hierarchies. Chunking must retain the binding relationship between titles and their corresponding content. Large drawing files have large file sizes and long parsing times, which easily trigger time-out limits. Frequently updated project documents require dynamically adjusted chunking parameters to prevent mismatches between old configurations and new documents.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Telecommunications engineering documents contain long paragraphs of construction descriptions and table fragments. This length retains context association, avoids splitting logic too finely to break construction logic, and prevents excessive length that causes context association loss |
chunkSplitter | Split by paragraph + title | Documents have clear chapter titles and independent construction paragraphs. This splitting method retains chapter logical association |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Parsing large telecommunications engineering drawing PDFs requires long processing time. This range covers the parsing time of most documents |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Large drawings and construction log files for telecommunications engineering construction have large sizes. This upper limit meets the upload needs of most project documents |
customPdfParse | Enabled | PDF documents contain a large number of vector construction drawings and dense tables. Custom parsing retains format and cell association relationships |
chunkSettingMode | Manual mode | Separate adjustment of chunking parameters is required for different types of telecommunications engineering documents, such as construction specifications and budget sheets. Manual mode supports fine-grained configuration |
Three Common Configuration Mistakes
- After uploading a large telecommunications engineering PDF to the locally deployed FastGPT v4.17.0, the interface displays a request failure after 2 minutes of parsing. Restarting the server does not resolve the issue. The cause is failure to adjust the
PARSE_FILE_TIMEOUT_SECONDSparameter. The default timeout period is shorter than the time required for large document parsing. - After uploading a telecommunications engineering budget Excel file with dense tables, some data fields are empty. The cause is failure to enable the
customPdfParseconfiguration. The default parsing logic cannot retain the association relationship of table cells, resulting in data loss. - After uploading a telecommunications engineering acceptance report PDF that includes images, the content related to the images is not parsed. The cause is failure to enable the image parsing associated configuration. The default logic only extracts PDF text content and does not cover the image parsing stage.
How to Confirm Correct Configuration
- Upload a typical telecommunications engineering construction PDF document, and check whether the parsed chunked content retains the association between chapter titles and their corresponding paragraphs.
- Upload a telecommunications engineering budget Excel file with dense tables, and check whether the parsed fields are complete with no abnormally missing content.
- Upload a large telecommunications engineering drawing file, and confirm that the parsing process does not trigger a time-out error.
- Upload a telecommunications engineering acceptance report PDF that includes images, and confirm that the parsing result includes the corresponding annotations or text description content of the images.
