+# 数据预处理模块
+
+独立的数据清洗工具，用于在正式分析前准备数据。
+
+## 功能
+
+- **数据合并**：将多个 Excel/CSV 文件合并为单一 CSV
+- **时间排序**：按时间列对数据进行排序
+- **目录管理**：标准化的原始数据和输出数据目录
+
+## 目录结构
+
+```
+project/
+├── raw_data/           # 原始数据存放目录
+│   ├── remotecontrol/  # 按数据来源分类
+│   └── ...
+├── cleaned_data/       # 清洗后数据输出目录
+│   ├── xxx_merged.csv
+│   └── xxx_sorted.csv
+└── data_preprocessing/ # 本模块
+```
+
+## 使用方法
+
+### 命令行
+
+```bash
+# 初始化目录结构
+python -m data_preprocessing.cli init
+
+# 合并 Excel 文件
+python -m data_preprocessing.cli merge --source raw_data/remotecontrol
+
+# 合并并按时间排序
+python -m data_preprocessing.cli merge --source raw_data/remotecontrol --sort-by SendTime
+
+# 指定输出路径
+python -m data_preprocessing.cli merge -s raw_data/remotecontrol -o cleaned_data/my_output.csv
+
+# 排序已有 CSV
+python -m data_preprocessing.cli sort --input some_file.csv --time-col SendTime
+
+# 原地排序（覆盖原文件）
+python -m data_preprocessing.cli sort --input data.csv --inplace
+```
+
+### Python API
+
+```python
+from data_preprocessing import merge_files, sort_by_time, Config
+
+# 合并文件
+output_path = merge_files(
+    source_dir="raw_data/remotecontrol",
+    output_file="cleaned_data/merged.csv",
+    pattern="*.xlsx",
+    time_column="SendTime"  # 可选：合并后排序
+)
+
+# 排序 CSV
+sorted_path = sort_by_time(
+    input_path="data.csv",
+    output_path="sorted_data.csv",
+    time_column="CreateTime"
+)
+
+# 自定义配置
+config = Config()
+config.raw_data_dir = "/path/to/raw"
+config.cleaned_data_dir = "/path/to/cleaned"
+config.ensure_dirs()
+```
+
+## 配置项
+
+| 配置项 | 默认值 | 说明 |
+|--------|--------|------|
+| `raw_data_dir` | `raw_data/` | 原始数据目录 |
+| `cleaned_data_dir` | `cleaned_data/` | 清洗输出目录 |
+| `default_time_column` | `SendTime` | 默认时间列名 |
+| `csv_encoding` | `utf-8-sig` | CSV 编码格式 |
+
+## 注意事项
+
+1. 本模块与 `DataAnalysisAgent` 完全独立，不会相互调用
+2. 合并时会自动添加 `_source_file` 列标记数据来源（可用 `--no-source-col` 禁用）
+3. Excel 文件会自动合并所有 Sheet
+4. 无效时间值在排序时会被放到最后
