"current_value": self.current_value,
}
def __str__(self) -> str:
return f"MyDevice({self.device_id}: {self.status})"
```
## 关键规则
### 1. 参数处理
所有动作方法的参数都可能以字符串形式传入,必须进行类型转换:
```python
async def my_action(self, value: float, **kwargs) -> bool:
# 始终进行类型转换
try:
value = float(value)
except (ValueError, TypeError) as e:
self.logger.error(f"参数类型错误: {e}")
return False
```
### 2. vessel 参数处理
vessel 参数可能是字符串ID或字典
```python
def extract_vessel_id(vessel: Union[str, dict]) -> str:
if isinstance(vessel, dict):
return vessel.get("id", "")
return str(vessel) if vessel else ""
```
### 3. 状态更新
使用 `self.data` 字典存储状态,属性读取状态:
```python
# 更新状态
self.data["status"] = "运行中"
self.data["current_speed"] = 300.0
# 读取状态(通过属性)
@property
def status(self) -> str:
return self.data.get("status", "待机")
```
### 4. 异步等待
使用 ROS 节点的 sleep 方法:
```python
# 正确
await self._ros_node.sleep(1.0)
# 避免(除非在纯 Python 测试环境)
await asyncio.sleep(1.0)
```
### 5. 进度反馈
长时间运行的操作需要提供进度反馈:
```python
while remaining > 0:
progress = (elapsed / total_time) * 100
self.data["status"] = f"运行中: {progress:.0f}%"
self.data["remaining_time"] = remaining
await self._ros_node.sleep(1.0)
```
## 虚拟设备
虚拟设备用于测试和演示,放在 `unilabos/devices/virtual/` 目录:
- 类名以 `Virtual` 开头
- 文件名以 `virtual_` 开头
- 模拟真实设备的行为和时序
- 使用表情符号增强日志可读性(可选)
## 工作站设备
工作站是组合多个设备的复杂设备:
```python
from unilabos.devices.workstation.workstation_base import WorkstationBase
class MyWorkstation(WorkstationBase):
"""组合工作站"""
async def execute_workflow(self, workflow: Dict[str, Any]) -> bool:
"""执行工作流"""
pass
```
## 设备注册
设备类开发完成后,需要在注册表中注册:
1. 创建/编辑 `unilabos/registry/devices/my_category.yaml`
2. 添加设备配置(参考 `virtual_device.yaml`
3. 运行 `--complete_registry` 自动生成 schema

# 协议编译器开发规范
## 概述
协议编译器负责将高级实验操作(如 Stir、Add、Filter编译为设备可执行的动作序列。
## 文件命名
- 位置: `unilabos/compile/`
- 命名: `{operation}_protocol.py`
- 示例: `stir_protocol.py`, `add_protocol.py`, `filter_protocol.py`
## 协议函数模板
```python
from typing import List, Dict, Any, Union
import networkx as nx
import logging
from .utils.unit_parser import parse_time_input
from .utils.vessel_parser import extract_vessel_id
logger = logging.getLogger(__name__)
def generate_{operation}_protocol(
G: nx.DiGraph,
vessel: Union[str, dict],
param1: Union[str, float] = "0",
param2: float = 0.0,
**kwargs
) -> List[Dict[str, Any]]:
"""
生成{操作}协议序列
Args:
G: 物理拓扑图 (NetworkX DiGraph)
vessel: 容器ID或Resource字典
param1: 参数1支持字符串单位如 "5 min"
param2: 参数2
**kwargs: 其他参数
Returns:
List[Dict]: 动作序列
Raises:
ValueError: 参数无效时
"""
# 1. 提取 vessel_id
vessel_id = extract_vessel_id(vessel)
# 2. 验证参数
if not vessel_id:
raise ValueError("vessel 参数不能为空")
if vessel_id not in G.nodes():
raise ValueError(f"容器 '{vessel_id}' 不存在于系统中")
# 3. 解析参数(支持单位)
parsed_param1 = parse_time_input(param1) # "5 min" -> 300.0
# 4. 查找设备
device_id = find_connected_device(G, vessel_id, device_type="my_device")
# 5. 生成动作序列
action_sequence = []
action = {
"device_id": device_id,
"action_name": "my_action",
"action_kwargs": {
"vessel": {"id": vessel_id}, # 始终使用字典格式
"param1": float(parsed_param1),
"param2": float(param2),
}
}
action_sequence.append(action)
logger.info(f"生成协议: {len(action_sequence)} 个动作")
return action_sequence
def find_connected_device(
G: nx.DiGraph,
vessel_id: str,
device_type: str = ""
) -> str:
"""
查找与容器相连的设备
Args:
G: 拓扑图
vessel_id: 容器ID
device_type: 设备类型关键字
Returns:
str: 设备ID
"""
# 查找所有匹配类型的设备
device_nodes = []
for node in G.nodes():
node_class = G.nodes[node].get('class', '') or ''
if device_type.lower() in node_class.lower():
device_nodes.append(node)
# 检查连接
if vessel_id and device_nodes:
for device in device_nodes:
if G.has_edge(device, vessel_id) or G.has_edge(vessel_id, device):
return device
# 返回第一个可用设备
if device_nodes:
return device_nodes[0]
# 默认设备
return f"{device_type}_1"
```
## 关键规则
### 1. vessel 参数处理
vessel 参数可能是字符串或字典,需要统一处理:
```python
def extract_vessel_id(vessel: Union[str, dict]) -> str:
"""提取vessel_id"""
if isinstance(vessel, dict):
# 可能是 {"id": "xxx"} 或完整 Resource 对象
return vessel.get("id", list(vessel.values())[0].get("id", ""))
return str(vessel) if vessel else ""
```
### 2. action_kwargs 中的 vessel
始终使用 `{"id": vessel_id}` 格式传递 vessel
```python
# 正确
"action_kwargs": {
"vessel": {"id": vessel_id}, # 字符串ID包装为字典
}
# 避免
"action_kwargs": {
"vessel": vessel_resource, # 不要传递完整 Resource 对象
}
```
### 3. 单位解析
使用 `parse_time_input` 解析时间参数:
```python
from .utils.unit_parser import parse_time_input
# 支持格式: "5 min", "1 h", "300", "1.5 hours"
time_seconds = parse_time_input("5 min") # -> 300.0
time_seconds = parse_time_input(120) # -> 120.0
time_seconds = parse_time_input("1 h") # -> 3600.0
```
### 4. 参数验证
所有参数必须进行验证和类型转换:
```python
# 验证范围
if speed < 10.0 or speed > 1500.0:
logger.warning(f"速度 {speed} 超出范围,修正为 300")
speed = 300.0
# 类型转换
param = float(param) if not isinstance(param, (int, float)) else param
```
### 5. 日志记录
使用项目日志记录器:
```python
logger = logging.getLogger(__name__)
def generate_protocol(...):
logger.info(f"开始生成协议...")
logger.debug(f"参数: vessel={vessel_id}, time={time}")
logger.warning(f"参数修正: {old_value} -> {new_value}")
```
## 便捷函数
为常用操作提供便捷函数:
```python
def stir_briefly(G: nx.DiGraph, vessel: Union[str, dict],
speed: float = 300.0) -> List[Dict[str, Any]]:
"""短时间搅拌30秒"""
return generate_stir_protocol(G, vessel, time="30", stir_speed=speed)
def stir_vigorously(G: nx.DiGraph, vessel: Union[str, dict],
time: str = "5 min") -> List[Dict[str, Any]]:
"""剧烈搅拌"""
return generate_stir_protocol(G, vessel, time=time, stir_speed=800.0)
```
## 测试函数
每个协议文件应包含测试函数:
```python
def test_{operation}_protocol():
"""测试协议生成"""
# 测试参数处理
vessel_dict = {"id": "flask_1", "name": "反应瓶1"}
vessel_id = extract_vessel_id(vessel_dict)
assert vessel_id == "flask_1"
# 测试单位解析
time_s = parse_time_input("5 min")
assert time_s == 300.0
if __name__ == "__main__":
test_{operation}_protocol()
```
## 现有协议参考
- `stir_protocol.py` - 搅拌操作
- `add_protocol.py` - 添加物料
- `filter_protocol.py` - 过滤操作
- `heatchill_protocol.py` - 加热/冷却
- `separate_protocol.py` - 分离操作
- `evaporate_protocol.py` - 蒸发操作

# 注册表配置规范
## 概述
注册表使用 YAML 格式定义设备和资源类型,是 Uni-Lab-OS 的核心配置系统。
## 目录结构
```
unilabos/registry/
├── devices/ # 设备类型注册
│ ├── virtual_device.yaml
│ ├── liquid_handler.yaml
│ └── ...
├── device_comms/ # 通信设备配置
│ ├── communication_devices.yaml
│ └── modbus_ioboard.yaml
└── resources/ # 资源类型注册
├── bioyond/
├── organic/
├── opentrons/
└── ...
```
## 设备注册表格式
### 基本结构
```yaml
device_type_id:
# 基本信息
description: "设备描述"
version: "1.0.0"
category:
- category_name
icon: "icon_device.webp"
# 类配置
class:
module: "unilabos.devices.my_module:MyClass"
type: python
# 状态类型(属性 -> ROS消息类型
status_types:
status: String
temperature: Float64
is_running: Bool
# 动作映射
action_value_mappings:
action_name:
type: UniLabJsonCommand # 或 UniLabJsonCommandAsync
goal: {}
feedback: {}
result: {}
schema: {...}
handles: {}
```
### action_value_mappings 详细格式
```yaml
action_value_mappings:
# 同步动作
my_sync_action:
type: UniLabJsonCommand
goal:
param1: param1
param2: param2
feedback: {}
result:
success: success
message: message
goal_default:
param1: 0.0
param2: ""
handles: {}
placeholder_keys:
device_param: unilabos_devices # 设备选择器
resource_param: unilabos_resources # 资源选择器
schema:
title: "动作名称参数"
description: "动作描述"
type: object
properties:
goal:
type: object
properties:
param1:
type: number
param2:
type: string
required:
- param1
feedback: {}
result:
type: object
properties:
success:
type: boolean
message:
type: string
required:
- goal
# 异步动作
my_async_action:
type: UniLabJsonCommandAsync
goal: {}
feedback:
progress: progress
current_status: status
result:
success: success
schema: {...}
```
### 自动生成的动作
以 `auto-` 开头的动作由系统自动生成:
```yaml
action_value_mappings:
auto-initialize:
type: UniLabJsonCommandAsync
goal: {}
feedback: {}
result: {}
schema: {...}
auto-cleanup:
type: UniLabJsonCommandAsync
goal: {}
feedback: {}
result: {}
schema: {...}
```
### handles 配置
用于工作流编辑器中的数据流连接:
```yaml
handles:
input:
- handler_key: "input_resource"
data_type: "resource"
label: "输入资源"
data_source: "handle"
data_key: "resources"
output:
- handler_key: "output_labware"
data_type: "resource"
label: "输出器皿"
data_source: "executor"
data_key: "created_resource.@flatten"
```
## 资源注册表格式
```yaml
resource_type_id:
description: "资源描述"
version: "1.0.0"
category:
- category_name
icon: ""
handles: []
init_param_schema: {}
class:
module: "unilabos.resources.my_module:MyResource"
type: pylabrobot # 或 python
```
### PyLabRobot 资源示例
```yaml
BIOYOND_Electrolyte_6VialCarrier:
category:
- bottle_carriers
- bioyond
class:
module: "unilabos.resources.bioyond.bottle_carriers:BIOYOND_Electrolyte_6VialCarrier"
type: pylabrobot
version: "1.0.0"
```
## 状态类型映射
Python 类型到 ROS 消息类型的映射:
| Python 类型 | ROS 消息类型 |
|------------|-------------|
| `str` | `String` |
| `bool` | `Bool` |
| `int` | `Int64` |
| `float` | `Float64` |
| `list` | `String` (序列化) |
| `dict` | `String` (序列化) |
## 自动完善注册表
使用 `--complete_registry` 参数自动生成 schema
```bash
python -m unilabos.app.main --complete_registry
```
这会:
1. 扫描设备类的方法签名
2. 自动生成 `auto-` 前缀的动作
3. 生成 JSON Schema
4. 更新 YAML 文件
## 验证规则
1. **device_type_id** 必须唯一
2. **module** 路径必须正确可导入
3. **status_types** 的类型必须是有效的 ROS 消息类型
4. **schema** 必须是有效的 JSON Schema
## 示例:完整设备配置
```yaml

description: ROS 2 集成开发规范
globs: ["unilabos/ros/**/*.py", "**/*_node.py"]

# ROS 2 集成开发规范
## 概述
Uni-Lab-OS 使用 ROS 2 作为设备通信中间件,基于 rclpy 实现。
## 核心组件
### BaseROS2DeviceNode
设备节点基类,提供:
- ROS Topic 自动发布(状态属性)
- Action Server 自动创建(设备动作)
- 资源管理服务
- 异步任务调度
```python
from unilabos.ros.nodes.base_device_node import BaseROS2DeviceNode
```
### 消息转换器
```python
from unilabos.ros.msgs.message_converter import (
convert_to_ros_msg,
convert_from_ros_msg_with_mapping,
msg_converter_manager,
ros_action_to_json_schema,
ros_message_to_json_schema,
)
```
## 设备与 ROS 集成
### post_init 方法
设备类必须实现 `post_init` 方法接收 ROS 节点:
```python
class MyDevice:
_ros_node: BaseROS2DeviceNode
def post_init(self, ros_node: BaseROS2DeviceNode):
"""ROS节点注入"""
self._ros_node = ros_node
```
### 状态属性发布
设备的 `@property` 属性会自动发布为 ROS Topic
```python
class MyDevice:
@property
def temperature(self) -> float:
return self._temperature
# 自动发布到 /{namespace}/temperature Topic
```
### Topic 配置装饰器
```python
from unilabos.utils.decorator import topic_config
class MyDevice:
@property
@topic_config(period=1.0, print_publish=False, qos=10)
def fast_data(self) -> float:
"""高频数据 - 每秒发布一次"""
return self._fast_data
@property
@topic_config(period=5.0)
def slow_data(self) -> str:
"""低频数据 - 每5秒发布一次"""
return self._slow_data
```
### 订阅装饰器
```python
from unilabos.utils.decorator import subscribe
class MyDevice:
@subscribe(topic="/external/sensor_data", qos=10)
def on_sensor_data(self, msg):
"""订阅外部Topic"""
self._sensor_value = msg.data
```
## 异步操作
### 使用 ROS 节点睡眠
```python
# 推荐使用ROS节点的睡眠方法
await self._ros_node.sleep(1.0)
# 不推荐直接使用asyncio可能导致回调阻塞
await asyncio.sleep(1.0)
```
### 获取事件循环
```python
from unilabos.ros.x.rclpyx import get_event_loop
loop = get_event_loop()
```
## 消息类型
### unilabos_msgs 包
```python
from unilabos_msgs.msg import Resource
from unilabos_msgs.srv import (
ResourceAdd,
ResourceDelete,
ResourceUpdate,
ResourceList,
SerialCommand,
)
from unilabos_msgs.action import SendCmd
```
### Resource 消息结构
```python
Resource:
id: str
name: str
category: str
type: str
parent: str
children: List[str]
config: str # JSON字符串
data: str # JSON字符串
sample_id: str
pose: Pose
```
## 日志适配器
```python
from unilabos.utils.log import info, debug, warning, error, trace
class MyDevice:
def __init__(self):
# 创建设备专属日志器
self.logger = logging.getLogger(f"MyDevice.{self.device_id}")
```
ROSLoggerAdapter 同时向自定义日志和 ROS 日志发送消息。
## Action Server
设备动作自动创建为 ROS Action Server
```yaml
# 在注册表中配置
action_value_mappings:
my_action:
type: UniLabJsonCommandAsync # 异步Action
goal: {...}
feedback: {...}
result: {...}
```
### Action 类型
- **UniLabJsonCommand**: 同步动作
- **UniLabJsonCommandAsync**: 异步动作支持feedback
## 服务客户端
```python
from rclpy.client import Client
# 调用其他节点的服务
response = await self._ros_node.call_service(
service_name="/other_node/service",
request=MyServiceRequest(...)
)
```
## 命名空间
设备节点使用命名空间隔离:
```
/{device_id}/ # 设备命名空间
/{device_id}/status # 状态Topic
/{device_id}/temperature # 温度Topic
/{device_id}/my_action # 动作Server
```
## 调试
### 查看 Topic
```bash
ros2 topic list
ros2 topic echo /{device_id}/status
```
### 查看 Action
```bash
ros2 action list
ros2 action info /{device_id}/my_action
```
### 查看 Service
```bash
ros2 service list
ros2 service call /{device_id}/resource_list unilabos_msgs/srv/ResourceList
```
## 最佳实践
1. **状态属性命名**: 使用蛇形命名法snake_case
2. **Topic 频率**: 根据数据变化频率调整,避免过高频率
3. **Action 反馈**: 长时间操作提供进度反馈
4. **错误处理**: 使用 try-except 捕获并记录错误
5. **资源清理**: 在 cleanup 方法中正确清理资源

## 设备测试
### 虚拟设备测试
```python
import pytest
import asyncio
from unittest.mock import MagicMock, AsyncMock
from unilabos.devices.virtual.virtual_stirrer import VirtualStirrer
class TestVirtualStirrer:
"""VirtualStirrer 测试"""
@pytest.fixture
def stirrer(self):
"""创建测试用搅拌器"""
device = VirtualStirrer(
device_id="test_stirrer",
config={"max_speed": 1500.0, "min_speed": 50.0}
)
# Mock ROS节点
mock_node = MagicMock()

"""测试无效速度"""
await stirrer.initialize()
# 速度超出范围

stir_time=5.0,
stir_speed=2000.0, # 超过max_speed
settling_time=0.0
)
assert result is False
assert "错误" in stirrer.status
```
### 异步测试配置
```python
# conftest.py
import pytest
import asyncio
@pytest.fixture(scope="session")
def event_loop():
"""创建事件循环"""
loop = asyncio.get_event_loop_policy().new_event_loop()
yield loop
loop.close()
```
## 资源测试
```python
import pytest
from unilabos.resources.resource_tracker import (
ResourceTreeSet,
ResourceTreeInstance,
)
def test_resource_tree_creation():
"""测试资源树创建"""
tree_set = ResourceTreeSet()
# 添加资源
resource = {"id": "res_1", "name": "Resource 1"}
tree_set.add_resource(resource)
# 验证
assert len(tree_set.all_nodes) == 1
assert tree_set.get_resource("res_1") is not None
def test_resource_tree_merge():
"""测试资源树合并"""
local_set = ResourceTreeSet()
remote_set = ResourceTreeSet()
# 设置数据...
local_set.merge_remote_resources(remote_set)
# 验证合并结果...
```
## ROS 消息测试
```python
import pytest
from unilabos.ros.msgs.message_converter import (
convert_to_ros_msg,
convert_from_ros_msg_with_mapping,
msg_converter_manager,
)
def test_message_conversion():
"""测试消息转换"""
# Python -> ROS
python_data = {"id": "test", "value": 42}
ros_msg = convert_to_ros_msg(python_data, MyMsgType)
assert ros_msg.id == "test"
assert ros_msg.value == 42
# ROS -> Python
result = convert_from_ros_msg_with_mapping(ros_msg, mapping)
assert result["id"] == "test"
```
## 协议测试
```python
import pytest
import networkx as nx
from unilabos.compile.stir_protocol import (
generate_stir_protocol,
extract_vessel_id,
)
@pytest.fixture
def topology_graph():
"""创建测试拓扑图"""
G = nx.DiGraph()
G.add_node("flask_1", **{"class": "flask"})
G.add_node("stirrer_1", **{"class": "virtual_stirrer"})
G.add_edge("stirrer_1", "flask_1")
return G
def test_generate_stir_protocol(topology_graph):
"""测试搅拌协议生成"""
actions = generate_stir_protocol(
G=topology_graph,
vessel="flask_1",
time="5 min",
stir_speed=300.0
)
assert len(actions) == 1
assert actions[0]["device_id"] == "stirrer_1"
assert actions[0]["action_name"] == "stir"
def test_extract_vessel_id():
"""测试vessel_id提取"""
# 字典格式
assert extract_vessel_id({"id": "flask_1"}) == "flask_1"
# 字符串格式
assert extract_vessel_id("flask_2") == "flask_2"
# 空值
assert extract_vessel_id("") == ""
```
## 测试标记
```python
# 慢速测试
@pytest.mark.slow
def test_long_running():
pass
# 需要网络
@pytest.mark.network
def test_network_call():
pass
# 需要ROS
@pytest.mark.ros
def test_ros_feature():
pass
```
运行特定标记的测试:
```bash
pytest -m "not slow" # 排除慢速测试
pytest -m ros # 仅ROS测试
```
## 覆盖率
```bash
# 生成覆盖率报告
pytest --cov=unilabos tests/
# HTML报告
pytest --cov=unilabos --cov-report=html tests/
```
## 最佳实践
1. **测试命名**: `test_{功能}_{场景}_{预期结果}`
2. **独立性**: 每个测试独立运行,不依赖其他测试
3. **Mock外部依赖**: 使用 unittest.mock 模拟外部服务
4. **参数化**: 使用 `@pytest.mark.parametrize` 减少重复代码
5. **fixtures**: 使用 fixtures 共享测试设置
6. **断言清晰**: 每个断言只验证一件事

# Uni-Lab-OS 项目开发规范
## 项目概述
Uni-Lab-OS 是一个实验室自动化操作系统,用于连接和控制各种实验设备,实现实验工作流的自动化和标准化。
## 技术栈
- **Python 3.11** - 核心开发语言
- **ROS 2** - 设备通信中间件 (rclpy)
- **Conda/Mamba** - 包管理 (robostack-staging, conda-forge)
- **FastAPI** - Web API 服务
- **WebSocket** - 实时通信
- **NetworkX** - 拓扑图管理
- **YAML** - 配置和注册表定义
- **PyLabRobot** - 实验室自动化库集成
- **pytest** - 测试框架
- **asyncio** - 异步编程
## 项目结构
```

├── resources/ # 资源定义
├── ros/ # ROS 2 集成
├── utils/ # 工具函数
└── workflow/ # 工作流管理
```
## 代码规范
### Python 风格
1. **类型注解**:所有函数必须使用类型注解
```python
def transfer_liquid(
source: str,
destination: str,
volume: float,
**kwargs
) -> List[Dict[str, Any]]:
```
2. **Docstring**:使用 Google 风格的文档字符串
```python
def initialize(self) -> bool:
"""
初始化设备
Returns:
bool: 初始化是否成功
"""
```
3. **导入顺序**
- 标准库
- 第三方库
- ROS 相关 (rclpy, unilabos_msgs)
- 项目内部模块
### 异步编程
1. 设备操作方法使用 `async def`
2. 使用 `await self._ros_node.sleep()` 而非 `asyncio.sleep()`
3. 长时间运行操作需提供进度反馈
```python
async def stir(self, stir_time: float, stir_speed: float, **kwargs) -> bool:
"""执行搅拌操作"""
start_time = time_module.time()
while True:
elapsed = time_module.time() - start_time
remaining = max(0, stir_time - elapsed)
self.data.update({
"remaining_time": remaining,
"status": f"搅拌中: {stir_speed} RPM"
})
if remaining <= 0:
break
await self._ros_node.sleep(1.0)
return True
```
### 日志规范
使用项目自定义日志系统:
```python
from unilabos.utils.log import logger, info, debug, warning, error, trace
# 在设备类中使用
self.logger = logging.getLogger(f"DeviceName.{self.device_id}")
self.logger.info("设备初始化完成")
```
## 设备驱动开发
### 设备类结构
```python
from unilabos.ros.nodes.base_device_node import BaseROS2DeviceNode
class MyDevice:
"""设备驱动类"""
_ros_node: BaseROS2DeviceNode
def __init__(self, device_id: str = None, config: Dict[str, Any] = None, **kwargs):
self.device_id = device_id or "unknown_device"
self.config = config or {}
self.data = {} # 设备状态数据
def post_init(self, ros_node: BaseROS2DeviceNode):
"""ROS节点注入"""
self._ros_node = ros_node
async def initialize(self) -> bool:
"""初始化设备"""
pass
async def cleanup(self) -> bool:
"""清理设备"""
pass
# 状态属性 - 自动发布为 ROS Topic
@property
def status(self) -> str:
return self.data.get("status", "待机")
```
### 状态属性装饰器
```python
from unilabos.utils.decorator import topic_config
class MyDevice:
@property
@topic_config(period=1.0, qos=10) # 每秒发布一次
def temperature(self) -> float:
return self._temperature
```
### 虚拟设备
虚拟设备放置在 `unilabos/devices/virtual/` 目录下,命名为 `virtual_*.py`
## 注册表配置
### 设备注册表 (YAML)
位置: `unilabos/registry/devices/*.yaml`
```yaml
my_device_type:
category:
- my_category
description: "设备描述"
version: "1.0.0"
class:
module: "unilabos.devices.my_device:MyDevice"
type: python
status_types:
status: String
temperature: Float64
action_value_mappings:
auto-initialize:
type: UniLabJsonCommandAsync
goal: {}
feedback: {}
result: {}
schema: {...}
```
### 资源注册表 (YAML)
位置: `unilabos/registry/resources/**/*.yaml`
```yaml
my_container:
category:
- container
class:
module: "unilabos.resources.my_resource:MyContainer"
type: pylabrobot
version: "1.0.0"
```
## 协议编译器
位置: `unilabos/compile/*_protocol.py`
### 协议生成函数模板
```python
from typing import List, Dict, Any, Union
import networkx as nx
def generate_my_protocol(
G: nx.DiGraph,
vessel: Union[str, dict],
param1: float = 0.0,
**kwargs
) -> List[Dict[str, Any]]:
"""
生成操作协议序列
Args:
G: 物理拓扑图
vessel: 容器ID或字典
param1: 参数1
Returns:
List[Dict]: 动作序列
"""
# 提取vessel_id
vessel_id = vessel if isinstance(vessel, str) else vessel.get("id", "")
# 查找设备
device_id = find_connected_device(G, vessel_id)
# 生成动作
action_sequence = [{
"device_id": device_id,
"action_name": "my_action",
"action_kwargs": {
"vessel": {"id": vessel_id},
"param1": float(param1)
}
}]
return action_sequence
```
## 测试规范
### 测试文件位置
- 单元测试: `tests/` 目录
- 设备测试: `tests/devices/`
- 资源测试: `tests/resources/`
- ROS消息测试: `tests/ros/msgs/`
### 测试命名
```python
# tests/devices/my_device/test_my_device.py
import pytest
def test_device_initialization():
"""测试设备初始化"""
pass
def test_device_action():
"""测试设备动作"""
pass
```
## 错误处理
```python
from unilabos.utils.exception import UniLabException
try:
result = await device.execute_action()
except ValueError as e:
self.logger.error(f"参数错误: {e}")
self.data["status"] = "错误: 参数无效"
return False
except Exception as e:
self.logger.error(f"执行失败: {e}")
raise
```
## 配置管理
```python
from unilabos.config.config import BasicConfig, HTTPConfig
# 读取配置
port = BasicConfig.port
is_host = BasicConfig.is_host_mode
# 配置文件: local_config.py
```
## 常用工具
### 单例模式
```python
from unilabos.utils.decorator import singleton
@singleton
class MyManager:
pass
```
### 类型检查
```python
from unilabos.utils.type_check import NoAliasDumper
yaml.dump(data, f, Dumper=NoAliasDumper)
```
### 导入管理
```python
from unilabos.utils.import_manager import get_class
device_class = get_class("unilabos.devices.my_device:MyDevice")
```
## Git 提交规范
提交信息格式:
```
<type>(<scope>): <subject>
<body>
```
类型:
- `feat`: 新功能
- `fix`: 修复bug
- `docs`: 文档更新
- `refactor`: 重构
- `test`: 测试相关
- `chore`: 构建/工具相关
