工作站与普通设备的核心差异:
| 维度 | 普通设备 | 工作站 | | 维度 | 普通设备 | 工作站 |
|------|---------|--------| |------|---------|--------|
| 基类 | 无(纯 Python 类 | `WorkstationBase` `ProtocolNode` | | 基类 | 纯 Python 类 | `WorkstationBase` / `ProtocolNode` |
| ROS 节点 | `BaseROS2DeviceNode` | `ROS2WorkstationNode` | | ROS 节点 | `BaseROS2DeviceNode` | `ROS2WorkstationNode` |
| 状态管理 | `self.data` 字典 | 通常不用 `self.data`,用 `@property` 直接访问 | | 状态管理 | `self.data` 字典 | `@property` 直接访问 |

| 物料 | 无 | `self.deck`PLR Deck | | 物料 | 无 | `self.deck`PLR Deck |
| 图文件角色 | `parent: null``parent: "<station>"` | `parent: null`,含 `children``deck` |
### 继承体系 ### 继承体系
`WorkstationBase` (ABC) → `ProtocolNode` (通用协议) / `BioyondWorkstation` (→ ReactionStation, DispensingStation) / `CoinCellAssemblyWorkstation` (硬件控制) ```
WorkstationBase (ABC)
├── BioyondWorkstation ← HTTP RPC + 资源同步
│ ├── BioyondReactionStation
│ └── BioyondDispensingStation
├── CoinCellAssemblyWorkstation ← Modbus/PLC
└── ProtocolNode ← 标准化学协议
```
### ROS 层 ### 子设备初始化流程
`ROS2WorkstationNode` 额外负责:初始化 children 子设备节点、为子设备创建 ActionClient、配置硬件代理、为 protocol_type 创建协议 ActionServer。 `ROS2WorkstationNode.__init__` → 遍历 `children`type=="device")→ `initialize_device_from_dict()` → 存入 `sub_devices` → 为每个动作创建 `ActionClient` → 识别通信设备(`serial_*`/`io_*`)→ `_setup_hardware_proxy()`

### 模板 A基于外部系统的工作站 根据类型选择模板(完整代码见 [templates.md](templates.md)
适用于与 LIMS/MES 等外部系统对接的场景。 | 类型 | 模板 | 关键要素 |
|------|------|---------|
| 外部系统 | Template A | `config` 接收 API 配置,`post_init` 启动 RPC/HTTP 服务 |
| 硬件控制 | Template B | `TCPClient` + CSV 寄存器映射,`use_node()` 读写 |
| Protocol | Template C | 直接使用 `ProtocolNode`,通常不需要自定义类 |
```python **所有模板的 `__init__` 必须接受 `deck` 和 `**kwargs`。**

### 模板 B基于硬件控制的工作站
适用于直接与 PLC/硬件通信的场景。

@property
def sys_status(self) -> str:
return str(self._read_register("SYS_STATUS"))
```
### 模板 CProtocol 工作站
适用于标准化学操作协议的场景,直接使用 `ProtocolNode`
```python
from typing import List, Optional
from pylabrobot.resources import Resource as PLRResource
from unilabos.devices.workstation.workstation_base import ProtocolNode
class MyProtocolStation(ProtocolNode):
"""Protocol 工作站 — 使用标准化学操作协议"""
def __init__(
self,
protocol_type: List[str],
deck: Optional[PLRResource] = None,
*args,
**kwargs,
):
super().__init__(protocol_type=protocol_type, deck=deck, *args, **kwargs)
```
> Protocol 工作站通常不需要自定义驱动类,直接使用 `ProtocolNode` 并在注册表和图文件中配置 `protocol_type` 即可。
--- ---
## 第四步:创建子设备驱动(如需要) ## 第四步:创建子设备(如需要)
工作站的子设备本身是独立设备。按 `docs/ai_guides/add_device.md` 的标准流程创建 子设备是独立设备,有自己的驱动类和注册表。完整模板见 [templates.md § 子设备模板](templates.md)
子设备的关键约束: ### 关键要点
- 在图文件中 `parent` 指向工作站 ID
- 图文件中在工作站的 `children` 数组里列出 1. **驱动类**:普通 Python 类,`self.data` 预填所有属性
- 如需硬件代理,在子设备的 `config.hardware_interface.name` 指向通信设备 ID 2. **注册表**`category` 包含工作站标识,`auto-` 前缀动作不创建 ActionClient
3. **图文件**`parent` 指向工作站 ID`type: "device"`
4. **代码访问**`self._children.get("reactor_1").driver_instance`
### 硬件代理模式
当子设备需要通过通信设备(串口/IO通信时
1. 通信设备 ID 必须以 `serial_``io_` 开头
2. 子设备注册表中声明 `hardware_interface: {name, read, write}`
3. 子设备实例的 `name` 属性值 = 通信设备 ID
4. ROS 节点自动将通信设备的 read/write 方法注入到子设备上

## 第六步:配置 Deck 资源(如需要) ## 第六步:配置物料系统(如需要)
如果工作站有物料管理需求,需要定义 Deck 类。 物料层级:`Deck``WareHouse``ResourceHolder` (site) → `BottleCarrier``Bottle`
### 使用已有 Deck 类 ### 快速流程
查看 `unilabos/resources/` 目录下是否有适用的 Deck 类。 1. **创建 Bottle**`unilabos/resources/<project>/bottles.py`)— 工厂函数,返回 `Bottle` 实例
2. **创建 Carrier**`.../bottle_carriers.py`)— 工厂函数,用 `create_ordered_items_2d` 定义槽位
3. **创建 WareHouse**`.../warehouses.py`)— 用 `warehouse_factory()` 创建堆栈
4. **创建 Deck**`.../decks.py`)— 继承 `pylabrobot.resources.Deck``setup()` 中放置 WareHouse
5. **注册表**`unilabos/registry/resources/<project>/`)— `class.type: pylabrobot`
6. **PLR 扩展**`unilabos/resources/plr_additional_res_reg.py`)— 导入新 Deck 类
### 创建自定义 Deck 完整代码模板见 [templates.md § 物料资源模板](templates.md)。
`unilabos/resources/<category>/decks.py` 中定义: ### 图文件中的 Deck 配置
```python 工作站节点引用 Deck
from pylabrobot.resources import Deck
from pylabrobot.resources.coordinate import Coordinate
```json
def MyStation_Deck(name: str = "MyStation_Deck") -> Deck: "deck": {
deck = Deck(name=name, size_x=2700.0, size_y=1080.0, size_z=1500.0) "data": {
# 在 deck 上定义子资源位置carrier、plate 等) "_resource_child_name": "my_deck",
return deck "_resource_type": "unilabos.resources.my_project.decks:MyStation_Deck"
}
}
``` ```
`unilabos/resources/<category>/` 下注册或通过注册表引用。 Deck 子节点:
```json
{
"id": "my_deck",
"parent": "my_station",
"type": "deck",
"class": "MyStation_Deck",
"config": {"type": "MyStation_Deck", "setup": true, "rotation": {"x": 0, "y": 0, "z": 0, "type": "Rotation"}}
}
```
> **`_resource_child_name`** 必须与 Deck 节点的 `id` 一致。

## 7. PLC/Modbus 完整框架
### 7.1 寄存器映射 CSV 格式
PLC 工作站使用 CSV 文件定义寄存器映射表。路径通常为工作站目录下的 `<name>.csv`
**CSV 列定义:**
| 列名 | 说明 | 值示例 |
|------|------|--------|
| `Name` | 寄存器节点名称(代码中引用的唯一标识) | `COIL_SYS_START_CMD` |
| `DataType` | 数据类型 | `BOOL`, `INT16`, `FLOAT32` |
| `InitValue` | 初始值(可选) | — |
| `Comment` | 注释(可选) | — |
| `Attribute` | 自定义属性(可选) | — |
| `DeviceType` | Modbus 设备类型 | `coil`, `hold_register`, `input_register`, `discrete_inputs` |
| `Address` | Modbus 地址 | `8010`, `11000` |
**CSV 示例:**
```csv
Name,DataType,InitValue,Comment,Attribute,DeviceType,Address,
COIL_SYS_START_CMD,BOOL,,系统启动命令,,coil,8010,
COIL_SYS_STOP_CMD,BOOL,,系统停止命令,,coil,8020,
COIL_SYS_RESET_CMD,BOOL,,系统复位命令,,coil,8030,
REG_MSG_ELECTROLYTE_VOLUME,INT16,,电解液体积,,hold_register,11004,
REG_DATA_OPEN_CIRCUIT_VOLTAGE,FLOAT32,,开路电压,,hold_register,10002,
REG_DATA_AXIS_X_POS,FLOAT32,,X轴位置,,hold_register,10004,
```
**命名约定:**
- 线圈:`COIL_` 前缀(读写布尔量)
- 保持寄存器:`REG_MSG_`(消息/命令寄存器)、`REG_DATA_`(数据/状态寄存器)
- `_CMD` 后缀:写入命令
- `_STATUS` 后缀:读取状态
### 7.2 TCPClient 初始化
```python
from unilabos.device_comms.modbus_plc.client import TCPClient, BaseClient
from unilabos.device_comms.modbus_plc.modbus import DataType, WorderOrder
# 创建 Modbus TCP 客户端
modbus_client = TCPClient(addr="192.168.1.100", port=502)
modbus_client.client.connect()
# 从 CSV 加载寄存器映射
import os
csv_path = os.path.join(os.path.dirname(__file__), 'register_map.csv')
nodes = BaseClient.load_csv(csv_path)
client = modbus_client.register_node_list(nodes)
```
### 7.3 寄存器读写操作
```python
# 读取线圈(布尔值)
result, err = client.use_node('COIL_SYS_START_STATUS').read(1)
is_started = result[0] if not err else False
# 写入线圈
client.use_node('COIL_SYS_START_CMD').write(True)
# 读取保持寄存器INT16
result, err = client.use_node('REG_DATA_ASSEMBLY_COIN_CELL_NUM').read(1)
# 读取保持寄存器FLOAT32需要 2 个寄存器)
result, err = client.use_node('REG_DATA_OPEN_CIRCUIT_VOLTAGE').read(2)
# 写入保持寄存器FLOAT32
client.use_node('REG_MSG_ELECTROLYTE_VOLUME').write(
100.0,
data_type=DataType.FLOAT32,
word_order=WorderOrder.LITTLE,
)
```
**FLOAT32 字节序注意:** 许多 PLC 使用 Big Byte Order + Little Word Order需要交换两个 16 位寄存器的顺序。参考 `coin_cell_assembly.py` 中的 `_decode_float32_correct` 函数。
### 7.4 ModbusWorkflow 生命周期
PLC 工作站的动作通过 `ModbusWorkflow` + `WorkflowAction` 组织,每个动作有 4 个生命周期阶段:
```python
from unilabos.device_comms.modbus_plc.client import ModbusWorkflow, WorkflowAction
# 定义动作的生命周期函数
def my_init(use_node):
"""初始化:设置参数"""
use_node('REG_MSG_ELECTROLYTE_VOLUME').write(
100.0, data_type=DataType.FLOAT32, word_order=WorderOrder.LITTLE
)
return True
def my_start(use_node):
"""启动:触发动作并轮询等待完成"""
use_node('COIL_SYS_START_CMD').write(True)
while True:
result, err = use_node('COIL_SYS_START_STATUS').read(1)
if not err and result[0]:
break
time.sleep(0.5)
return True
def my_stop(use_node):
"""停止:复位触发信号"""
use_node('COIL_SYS_START_CMD').write(False)
return True
def my_cleanup(use_node):
"""清理:无论成功失败都执行"""
use_node('COIL_SYS_RESET_CMD').write(True)
# 组合成工作流
workflow = ModbusWorkflow(
name="我的加工流程",
actions=[
WorkflowAction(init=my_init, start=my_start, stop=my_stop, cleanup=my_cleanup)
],
)
# 执行
client.run_modbus_workflow(workflow)
```
**生命周期执行顺序:** `init``start``stop``cleanup`cleanup 始终执行,即使前序步骤失败)
### 7.5 PLC 工作站中的握手循环
纽扣电池组装站的典型 PLC 交互模式(信息交换握手):
```python
async def _send_msg_to_plc(self, data: dict):
"""向 PLC 发送消息并等待确认"""
# 1. 写入数据寄存器
for key, value in data.items():
self._write_register(key, value)
# 2. 发送"消息已准备好"信号
self._write_coil('COIL_UNILAB_SEND_MSG_SUCC_CMD', True)
# 3. 等待 PLC 读取确认
while not self._read_coil('COIL_REQUEST_REC_MSG_STATUS'):
await self._ros_node.sleep(0.3)
# 4. 撤销发送信号
self._write_coil('COIL_UNILAB_SEND_MSG_SUCC_CMD', False)
async def _recv_msg_from_plc(self) -> dict:
"""等待 PLC 发送消息"""
# 1. 等待 PLC 发送信号
while not self._read_coil('COIL_REQUEST_SEND_MSG_STATUS'):
await self._ros_node.sleep(0.3)
# 2. 读取数据寄存器
data = {}
for key in self._recv_registers:
data[key] = self._read_register(key)
# 3. 发送"已收到"确认
self._write_coil('COIL_UNILAB_REC_MSG_SUCC_CMD', True)
# 4. 等待 PLC 撤销发送信号
while self._read_coil('COIL_REQUEST_SEND_MSG_STATUS'):
await self._ros_node.sleep(0.3)
# 5. 撤销确认信号
self._write_coil('COIL_UNILAB_REC_MSG_SUCC_CMD', False)
return data
```
### 7.6 JSON 驱动的 PLC 工作流
PLC 工作站还支持通过 JSON 描述工作流,无需编写 Python 代码。使用 `BaseClient.execute_procedure_from_json`
```json
{
"register_node_list_from_csv_path": {"path": "register_map.csv"},
"create_flow": [
{
"name": "初始化系统",
"action": [
{
"address_function_to_create": [

### 8.6 初始化时序
```
1. ROS2WorkstationNode.__init__
├── 创建 BioyondReactionStation 实例__init__
├── 加载 DeckBIOYOND_PolymerReactionStation_Deck, setup=true → 创建 6 个 WareHouse
├── 初始化 reactor_1~5BioyondReactor 实例)→ sub_devices
└── 为每个 reactor 创建 ActionClient
2. BioyondReactionStation.post_init(ros_node)
├── 初始化 BioyondV1RPCHTTP 客户端)
├── 初始化 BioyondResourceSynchronizer
├── 启动 ConnectionMonitor30s 轮询)
├── 启动 WorkstationHTTPService接收回调
├── sync_from_external()(从 Bioyond 拉取物料到 Deck
└── update_resource([self.deck])(上传 Deck 到云端)
```
### 8.7 物料同步流程
```
外部入库:
Bioyond API → stock_material() → 获取物料列表
→ resource_bioyond_to_plr() → 转为 PLR Bottle/Carrier
→ deck.warehouses["堆栈1左"]["A01"] = carrier
→ update_resource([deck])
外部变更回调:
Bioyond POST /report/material_change
→ WorkstationHTTPService 接收
→ process_material_change_report()
→ 更新 Deck 中的资源
→ update_resource([affected_resource])
```
### 8.8 工作站动作执行流程(以 reactor_taken_in 为例)
```python
async def reactor_taken_in(self, assign_material_name, cutoff, temperature, **kwargs):
# 1. 从 config 获取工作流 UUID
workflow_id = self.config["workflow_mappings"]["reactor_taken_in"]
# 2. 构建工序参数
sections = self._build_sections(temperature, cutoff, ...)
# 3. 合并到工作流序列
self._workflow_sequence.append({"name": "reactor_taken_in", ...})
# 4. 调用外部系统创建工单
result = self.hardware_interface.create_order(order_data)
# 5. 等待外部系统完成(通过 HTTP 回调通知)
# process_order_finish_report 被回调时更新状态
return {"success": True}
```

## 子设备模板
### 驱动类
```python
class MyReactor:
def __init__(self, **kwargs):
self.data = {
"temperature": 0.0,
"status": "Idle",
}
async def update_metrics(self, metrics_json: str, **kwargs):

metrics = json.loads(metrics_json)
self.data["temperature"] = metrics.get("temperature", 0.0)
self.data["status"] = metrics.get("status", "Idle")
return {"success": True}
```
### 注册表
```yaml

```
> `auto-` 前缀动作不创建 ActionClient仅供工作站驱动内部调用。
### 图文件节点

"type": "device",
"class": "reaction_station.reactor",
"position": {"x": 1150, "y": 300, "z": 0},
"config": {},
"data": {}
}
```
### 代码中访问子设备
```python
child_node = self._children.get("reactor_1")
child_node.driver_instance.update_metrics(data)
child = self._ros_node.sub_devices.get("reactor_1")
child.driver_instance.data["temperature"]
```
### 硬件代理配置
通信设备节点ID 以 `serial_``io_` 开头):
```json
{
"id": "serial_port_1",
"parent": "my_station",
"type": "device",
"class": "serial_device",
"config": {
"hardware_interface": {
"name": "hardware_interface_name",
"read": "read_method",
"write": "write_method"
}
}
}
```
子设备注册表中声明代理:
```yaml
my_sub_device:
class:
hardware_interface:
name: hardware_interface_name # 属性名,值为通信设备 ID
read: read_from_device # 注入的读方法
write: write_to_device # 注入的写方法
```
ROS 节点初始化时自动检测 `name` 属性值是否为另一子设备 ID若是则注入通信设备的 read/write 方法。

### Bottle 工厂函数
```python
from unilabos.resources.itemized_carrier import Bottle
def My_Reagent_Bottle(
name: str,
diameter: float = 70.0,
height: float = 120.0,
max_volume: float = 500000.0, # 单位 μL500mL = 500000
barcode: str = None,
) -> Bottle:
return Bottle(
name=name, diameter=diameter, height=height,
max_volume=max_volume, barcode=barcode,
model="My_Reagent_Bottle",
)
```
### BottleCarrier 工厂函数
```python
from pylabrobot.resources import ResourceHolder
from pylabrobot.resources.carrier import create_ordered_items_2d
from unilabos.resources.itemized_carrier import BottleCarrier
def My_6SlotCarrier(name: str) -> BottleCarrier:
sites = create_ordered_items_2d(
klass=ResourceHolder,
num_items_x=3, num_items_y=2,
dx=10.0, dy=10.0, dz=5.0,
item_dx=42.0, item_dy=35.0,
size_x=20.0, size_y=20.0, size_z=50.0,
)
carrier = BottleCarrier(
name=name, size_x=146.0, size_y=80.0, size_z=55.0,
sites=sites, model="My_6SlotCarrier",
)
carrier.num_items_x = 3
carrier.num_items_y = 2
carrier.num_items_z = 1
return carrier
```
### WareHouse 工厂函数
```python
from unilabos.resources.warehouse import warehouse_factory
def my_warehouse_4x4(name: str) -> "WareHouse":
return warehouse_factory(
name=name,
num_items_x=4, num_items_y=4, num_items_z=1,
dx=137.0, dy=96.0, dz=120.0,
item_dx=137.0, item_dy=125.0, item_dz=10.0,
resource_size_x=127.0, resource_size_y=85.0, resource_size_z=100.0,
model="my_warehouse_4x4",
)
```
### Deck 类
```python
from pylabrobot.resources import Deck, Coordinate
class MyStation_Deck(Deck):
def __init__(
self,
name: str = "MyStation_Deck",
size_x: float = 2700.0,
size_y: float = 1080.0,
size_z: float = 1500.0,
category: str = "deck",
setup: bool = False,
) -> None:
super().__init__(name=name, size_x=size_x, size_y=size_y, size_z=size_z)
if setup:
self.setup()
def setup(self) -> None:
self.warehouses = {
"堆栈A": my_warehouse_4x4("堆栈A"),
"堆栈B": my_warehouse_4x4("堆栈B"),
}
self.warehouse_locations = {
"堆栈A": Coordinate(-200.0, 400.0, 0.0),
"堆栈B": Coordinate(2350.0, 400.0, 0.0),
}
for wh_name, wh in self.warehouses.items():
self.assign_child_resource(wh, location=self.warehouse_locations[wh_name])
```
### 资源注册表
```yaml
# unilabos/registry/resources/<project>/bottles.yaml
My_Reagent_Bottle:
category: [bottles]
class:
module: unilabos.resources.my_project.bottles:My_Reagent_Bottle
type: pylabrobot
# unilabos/registry/resources/<project>/decks.yaml
MyStation_Deck:
category: [deck]
class:
module: unilabos.resources.my_project.decks:MyStation_Deck
type: pylabrobot
registry_type: resource
```
### PLR 扩展注册
新 Deck 类需要在 `unilabos/resources/plr_additional_res_reg.py` 中导入:
```python
def register():
from unilabos.resources.my_project.decks import MyStation_Deck
```
