This dataset collects operational data via the moving walkway IoT platform to realize real-time equipment monitoring and maintainability assessment. The platform calculates the equipment maintainability index based on 8 key monitoring indicators, including equipment operating time, motor temperature, vibration frequency, noise level, current fluctuation, handrail speed, brake system response time and sensor data integrity, and divides the maintainability status into five grades: Excellent, Good, Fair, Attention Required and Immediate Maintenance Required. For internal enterprise use, this data provides: intuitive equipment status assessment results to support management decision-making; timely maintenance demand early warnings to reduce failure risks; preventive maintenance suggestions to optimize maintenance plans; full-life-cycle data tracking of equipment to improve management efficiency. For the moving walkway industry and other industries, the operational maintainability index data can help equipment manufacturers optimize product design and improve equipment reliability based on actual operational data; maintenance service providers develop predictive maintenance models to provide accurate maintenance services; insurance institutions evaluate risks and optimize insurance product pricing based on maintainability indicators; industry standard-setting organizations provide data support for standards such as equipment operating parameter ranges and maintenance specifications; through the multi-dimensional application of data value, the moving walkway industry is promoted towards digitalization and standardization. The operational data is collected via the moving walkway IoT platform to complete real-time equipment monitoring and maintainability assessment. The preprocessed data is input into a custom maintainability assessment model, and the equipment maintainability index is calculated based on the status values of each monitoring indicator. 1. Data Collection and Preprocessing: Read equipment operational data from the IoT platform, including the following 8 key monitoring indicators: "Equipment operating time (min)", "Motor temperature (℃)", "Vibration frequency (Hz)", "Noise level (dB)", "Current fluctuation (A)", "Brake system response time (s)", "Sensor data integrity (%)", "Last maintenance interval (days)". 2. Maintainability Index Calculation: A custom weighted model is used to calculate the maintainability index, with the calculation process as follows: 1) Data Standardization: Use MinMaxScaler to standardize all indicators, mapping the values to the range of 0-1. 2) Weight Assignment: Assign weights to each indicator to reflect their impact on maintainability: - Equipment operating time (min): -0.1 - Motor temperature (℃): -0.15 - Vibration frequency (Hz): -0.15 - Noise level (dB): -0.1 - Current fluctuation (A): -0.1 - Brake system response time (s): -0.15 - Sensor data integrity (%): 0.15 - Last maintenance interval (days): -0.1 3) Maintainability Index Calculation Formula: Maintainability Index = Σ(Standardized Indicator Value * Corresponding Weight) 4) Index Normalization: Linearly map the calculated maintainability index to the range of 0-100. 3. Maintainability Status Assessment Divide the equipment operational status into five grades based on the calculated 0-100 maintainability index: 1) Excellent: Maintainability Index ≥ 80 2) Good: 60 ≤ Maintainability Index < 80 3) Fair: 40 ≤ Maintainability Index < 60 4) Attention Required: 20 ≤ Maintainability Index < 40 5) Immediate Maintenance Required: Maintainability Index < 20.
