+# 换电站 MQTT 协议解析器
+
+该软件包提供了一个基于 Python 的换电站 MQTT 协议实现，符合 V2.6.2 规范。
+
+## 主要功能
+
+- 完整实现所有消息类型（状态类、事件类、请求/响应类）
+- 支持加密功能（RSA/AES）
+- 全面的消息字段验证
+- 简单易用的消息创建和解析 API
+- 完整的测试覆盖
+
+## 安装方法
+
+```bash
+pip install -e .
+```
+
+## 快速开始
+
+下面是创建和解析站点状态消息的简单示例：
+
+```python
+from mqtt_protocol import StationStateMessage
+
+# 创建站点状态消息
+state_msg = StationStateMessage.create(
+    state=1,  # 运营状态
+    smoke="1,1,1,1",  # 所有烟感正常
+    fire=1,  # 消防系统正常
+    temp=25,  # 温度
+    humid=60,  # 湿度
+    totalElect=1000.5  # 总电量
+)
+
+# 转换为 JSON
+json_data = state_msg.to_json()
+
+# 从 JSON 解析
+parsed_msg = StationStateMessage.from_json(json_data)
+```
+
+## 消息类型
+
+### 状态类消息
+- 换电站属性信息
+- 换电站状态
+- 机器人状态
+- 换电车辆状态
+- 换电过程实时状态
+- 电池状态
+- 充电机状态
+
+### 事件类消息
+- 充电事件记录
+- 换电事件记录
+- 故障告警事件记录
+
+### 请求/响应类消息
+- 换电启动请求/响应
+- 充电启动请求/响应
+- 记录查询请求/响应
+- 费率模型查询请求/响应
+

+```bash
+pytest tests/
+```
+
+## 示例代码
+
+查看 `examples/` 目录中的使用示例：
+
+```bash
+python examples/state_example.py    # 状态消息示例
+python examples/event_example.py    # 事件消息示例
+python examples/request_example.py  # 请求响应示例
+```
+
+## 协议文档
+
+详细的协议规范请参见 `docs/protocol_spec.md`。
+
+## 系统要求
+
+- Python 3.7+
+- pycryptodome>=3.15.0（加密库）
+- pytest>=7.0.0（测试用）
+- paho-mqtt>=1.6.1（MQTT客户端）
+- python-dateutil>=2.8.2（日期处理）
+
+## 主要功能模块说明
+
+### 1. 基础消息模块 (base_message.py)
+- 定义了所有消息的基础类
+- 包含消息头部处理
+- 提供 JSON 序列化和反序列化功能
+
+### 2. 状态消息模块 (state_messages.py)
+- 实现各类状态信息的处理
+- 包括站点状态、设备状态等
+- 支持实时状态更新
+
+### 3. 事件消息模块 (event_messages.py)
+- 处理充电、换电等事件记录
+- 支持事件确认机制
+- 包含事件重试逻辑
+
+### 4. 请求响应模块 (request_response.py)
+- 实现所有请求响应类消息
+- 支持同步和异步请求处理
+- 包含超时和重试机制
+
+### 5. 加密模块 (encryption_handler.py)
+- 实现 RSA 和 AES 加密
+- 提供密钥管理功能
+- 支持安全通信
+
+## 使用注意事项
+
+1. 在使用前确保正确配置 MQTT 服务器连接信息
+2. 注意处理所有可能的异常情况
+3. 建议在生产环境中启用加密功能
+4. 定期检查并处理消息重试队列
