This data product integrates over 160,000 data entries of IoT operation and maintenance data of general intelligent manufacturing equipment (such as stamping automatic die-casting machines, high-precision machining machines, continuous production lines, etc.) from the past three years, and constructs an intelligent maintenance decision-making system of "Equipment Health Index (HI) + Productivity Efficiency Index (PEI)", while deeply integrating the AI data inquiry interaction engine and intelligent inspection early warning module. It analyzes the per-unit-time production cost of core motor components via model algorithms, conducts anomaly data analysis on maintenance and inspection of core accessory production equipment such as cutters, rotors, and silicon steel sheets, and provides AI-guided key opinion suggestions. It enables real-time query of multi-dimensional operating characteristics of any equipment/production line via natural language dialogue. It performs streaming monitoring on real-time IoT data based on real-time status and historical models, and pushes graded early warning notifications and specific handling suggestions to relevant responsible persons immediately, realizing the leap from passive response to active intervention. This data-driven mode upgrades the traditional fixed maintenance and experience-based production scheduling into an accurate management paradigm of active prediction and human-machine collaboration. It can help enterprises reduce unnecessary inspection costs by more than 20%, avoid unplanned downtime losses, significantly improve equipment overall efficiency and resource energy efficiency balance level, promote the industry to upgrade from "passive emergency repair + extensive production" to "active prediction + precise control", and empower the entire industry to reduce costs and increase efficiency. 1. Data Collection and Preprocessing Source: Real-time data collection is carried out via IoT terminals deployed in local leading enterprises in the industry. Core collected data include equipment online status, operating duration, alarm duration, offline duration, cumulative output, equipment utilization rate, etc. A complete data processing workflow is executed daily, including noise reduction (such as smoothing filtering), data cleaning (removing outliers, filling missing values) and standardization processing (such as unifying dimensions), to ensure data integrity, accuracy and comparability. 2. Core Index Calculation Equipment Health Index (HealthIndex, HI): Used to quantify the comprehensive health status of equipment. Calculation formula: HI = (Operating Duration / Online Duration) × 0.4 + (1 - Alarm Duration / Online Duration) × 0.3 + (1 - Offline Duration / Online Duration) × 0.3. Value range: 0-1 (the closer to 1, the healthier the equipment). Productivity Efficiency Index (ProductivityEfficiencyIndex, PEI): Used to quantify the effective production capacity per unit time. Calculation formula: PEI = (Total Time for Production Output × Equipment Utilization Rate) / Cumulative Output 3. Status Judgment and Decision Rules Equipment Health Status Judgment: Fault Status: HI < 0.5 → Shut down for maintenance immediately. Warning Status: 0.5 ≤ HI < 0.85 → Increase inspection frequency and carry out preventive maintenance. Normal Status: HI ≥ 0.85 → Maintain routine operation and maintenance. Production Optimization Scheduling: Sort equipment in descending order according to PEI. When formulating production plans, give priority to activating equipment with high PEI, optimize equipment load distribution, so as to improve overall capacity utilization rate. 4. AI Data Inquiry Interaction and Intelligent Decision Support Constructs a natural language question-and-answer interface for equipment administrators. The system recognizes user intentions through semantic parsing, dynamically queries real-time and historical indicators such as operating duration, production quantity, offline duration and standby duration of specified equipment/time periods, and integrates equipment health status judgment results and productivity efficiency sorting strategies to automatically generate customized suggestion texts (such as "maintenance priority", "production scheduling adjustment plans", "abnormal disposal guidelines"), realizing closed-loop intelligent services from data query to management decision-making. At the same time, it performs windowed monitoring on real-time IoT data streams. When the Equipment Health Index (HI) falls below the threshold on the same day, the Productivity Efficiency Index (PEI) drops by more than 20% suddenly, or key indicators (alarm duration, offline duration) have step changes, the AI automatically judges the anomaly level, sends graded early warning notifications to pre-set responsible persons via message push, SMS and other methods, and associates processing measures based on the rule base (such as "It is recommended to check the spindle lubrication system immediately", "It is recommended to switch to standby equipment and adjust order scheduling") to assist managers in responding quickly.
