实时记录不同粉尘浓度环境下的电气控制柜绝缘电阻测试数据，包括测试样品编号、测试时间、粉尘浓度/(mg/m³)、绝缘电阻/MΩ等字段。
2.数据预处理：
(1) 对采集的数据进行去噪处理，确保数据准确性。
(2) 将历史采集的数据（包含本次采集）进行聚合，形成数据集X，并针对数据集X中的绝缘电阻字段，计算出其平均值。
3.计算线性回归斜率a和截距b：
(1) 基于数据集X（以粉尘浓度为自变量、绝缘电阻为因变量），运用SLOPE函数，基于最小二乘法原理确定斜率a，运用INTERCEPT函数确定截距b。
(2) 斜率a表示单位粉尘浓度变化对绝缘电阻的影响程度，截距b表示基准粉尘浓度下电气控制柜的绝缘电阻值。
4.结果运用：
(1) 计算比例系数k：k=|a/绝缘电阻平均值|×100%。
(2) 若k≥15%，则判定为"高影响"，若8%≤k＜15%，则判定为"中影响"，若k＜8%，则判定为"低影响"。

This dataset focuses on analyzing the impact of dust concentration on the insulation resistance of electrical control cabinets, providing important decision-making support for the company (as an electrical equipment manufacturer) and external stakeholders, with significant application value. Its application value is specifically reflected in the following aspects:
1. Optimizing product protection design for industrial dust environments:
The company can analyze the impact of dust concentration on insulation resistance to improve the dust-proof sealing structure of control cabinets (such as adding air filtration systems, optimizing heat dissipation duct design), develop dust-resistant surface treatment processes, and formulate protection standards applicable to high-dust working conditions, thereby significantly improving the operational reliability of equipment in harsh industrial environments.
2. Promoting industrial technological progress:
This dataset can provide experimental support for equipment R&D in high-dust industries such as mining, cement, and metallurgy, promote the development of dust-proof insulating materials and dust deposition early warning technologies, and advance the improvement of test methods and evaluation systems for dust-proof grade standards in related industries.

1. Data Collection:
Real-time recording of insulation resistance test data of electrical control cabinets under different dust concentration environments, including fields such as test sample number, test time, dust concentration/(mg/m³), insulation resistance/MΩ, etc.
2. Data Preprocessing:
(1) Denoise the collected data to ensure data accuracy.
(2) Aggregate the historically collected data (including this collection) to form dataset X, and calculate the average value of the insulation resistance field in dataset X.
3. Calculation of Linear Regression Slope a and Intercept b:
(1) Based on dataset X (with dust concentration as the independent variable and insulation resistance as the dependent variable), use the SLOPE function to determine the slope a based on the principle of least squares, and use the INTERCEPT function to determine the intercept b.
(2) The slope a represents the degree of impact of unit dust concentration change on insulation resistance, and the intercept b represents the insulation resistance value of the electrical control cabinet under the reference dust concentration.
4. Result Application:
(1) Calculate the proportional coefficient k: k = |a / average insulation resistance| × 100%.
(2) If k ≥ 15%, it is judged as "high impact"; if 8% ≤ k < 15%, it is judged as "medium impact"; if k < 8%, it is judged as "low impact".
