# 换电站 MQTT 协议解析器
|
# Swap Station Project
|
||||||
|
A PyCharm project for connecting to a swap station via MQTT on Windows.
|
||||||
|
|
||||||
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。
|
## Structure
|
||||||
|
- `src/common/`: Shared configurations and encryption utilities.
|
||||||
|
- `src/key_management/`: Handles key exchange and AES key storage.
|
||||||
|
- `src/state_receiver/`: Receives state information messages.
|
||||||
|
- `src/event_receiver/`: Receives event record messages.
|
||||||
|
- `data/`: Stores AES keys (aes_key.bin, aes_iv.bin).
|
||||||
|
- `logs/`: Optional log files.
|
||||||
|
|
||||||
## 主要功能
|
## Setup
|
||||||
|
1. Install EMQX and configure authentication.
|
||||||
|
2. Run `pip install -r requirements.txt` in the PyCharm terminal.
|
||||||
|
3. Replace the platform public key in `common.py`.
|
||||||
|
4. Run `key_management.py` first, then `state_receiver.py` and `event_receiver.py`.
|
||||||
|
|
||||||
- 完整实现所有消息类型（状态类、事件类、请求/响应类）
|
## Usage
|
||||||
- 支持加密功能（RSA/AES）
|
- Use PyCharm's "Run Configurations" to execute each module.
|
||||||
- 全面的消息字段验证
|
- Simulate messages with MQTTX or a test script.
|
||||||
- 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
|
|
||||||
