What the data for this category looks like
The financial report data of power grid equipment enterprises comes from periodic reports publicly disclosed by domestic and overseas stock exchanges, and official investor relations announcements issued by enterprises. Data updates follow fixed quarterly, semi-annual, and annual cycles. Temporary announcements covering major orders and technological breakthroughs are released additionally. Document structures include consolidated financial statements, discussion and analysis of operating conditions, revenue breakdowns of core business segments, detailed R&D investment records, and other content. Fields involve revenue proportion of power grid-specific equipment, amount of in-hand orders for power grid projects, indicators related to grid-connected equipment, and more. Common units are 100 million yuan, percentage, and number of sets/units.
Constraints imposed on tool calling and plugins
The fixed update cycle requires tool calling plugins to configure scheduled synchronization tasks. Match the financial report disclosure time window to trigger data pulling and parsing, and avoid missing the latest announcements. Exclusive requirements for segmented business fields require loading custom extraction templates for power grid equipment revenue proportion and in-hand power grid project orders when calling tools. Replace general financial report extraction logic with these templates. Long document structures create parsing pressure. Configure reasonable segmentation and context splicing rules for the plugin to avoid losing cross-page business-related information after splitting. Differences in publicly disclosed formats require tools to automatically identify unit markings in financial reports. Complete unified conversion of revenue and order amounts to ensure numerical consistency in subsequent analysis.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Power grid equipment financial report PDFs often include multi-page business breakdown content. A sufficiently long parsing duration prevents mid-process timeouts |
chunkSize | 1000–1500 characters | Adapt to long paragraph business descriptions in financial reports while retaining cross-paragraph business-related information |
customExtractPrompt | For financial reports of power grid equipment enterprises, extract the revenue proportion of power transmission/substation equipment, amount of in-hand power grid project orders, and proportion of R&D investment in revenue | Match the exclusive field requirements of power grid equipment financial reports, replacing general extraction logic |
scheduleCron | 0 0 2 10-15,25-30 * * | Align with the fixed disclosure cycle of listed company financial reports, ensuring the latest announcements are pulled |
similarityThreshold | 0.75–0.85 | Filter paragraphs strongly related to power grid business in financial reports, removing irrelevant financial notes |
pluginCallRateLimit | 5 requests per minute | Avoid frequent calls to exchange public APIs from triggering access restrictions |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Errors
- The financial report parsing plugin returns the error
connect ECONNREFUSED 172.23.0.2:3001. This occurs when the deployed plugin service fails to start normally, or the port mapping configuration is incorrect. - The plugin returns empty results for power grid equipment-specific revenue fields. This happens when the custom extraction template for power grid equipment business is not loaded, and general financial report extraction logic cannot identify segmented fields.
- Continuous calls to the financial report interface trigger the 429 Too Many Requests status code. This is caused by missing plugin call rate limit configuration, exceeding the access threshold of the public data interface.
How to Confirm Configuration is Successful
- Manually upload a publicly available financial report PDF of a listed power grid equipment company, and check if the parsing result correctly extracts exclusive fields such as the revenue proportion of power transmission and substation equipment.
- Review scheduled task logs to confirm if data pulling and parsing tasks automatically trigger during the financial report disclosure window.
- Simulate high-frequency calls to the plugin interface, check if the rate limit triggers, and confirm the configured call limit takes effect.
- Review the port listening status of the plugin service to confirm no trigger conditions for connection refusal errors exist.
