bb0c68fd18 Add PLC communication guide (#264)
* Add post process station and related resources

- Created JSON configuration for post_process_station and its child post_process_deck.
- Added YAML definitions for post_process_station, bottle carriers, bottles, and deck resources.
- Implemented Python classes for bottle carriers, bottles, decks, and warehouses to manage resources in the post process.
- Established a factory method for creating warehouses with customizable dimensions and layouts.
- Defined the structure and behavior of the post_process_deck and its associated warehouses.

* feat(post_process): add post_process_station and related warehouse functionality

- Introduced post_process_station.json to define the post-processing station structure.
- Implemented post_process_warehouse.py to create warehouse configurations with customizable layouts.
- Added warehouses.py for specific warehouse configurations (4x3x1).
- Updated post_process_station.yaml to reflect new module paths for OpcUaClient.
- Refactored bottle carriers and bottles YAML files to point to the new module paths.
- Adjusted deck.yaml to align with the new organizational structure for post_process_deck.

* Add PLC communication guide for AI4M

Add a comprehensive developer guide (docs/developer_guide/add_PLC.md) describing the PLC integration standard used by Uni-Lab for workstation devices, using the AI4M implementation as reference. Covers rationale for using OPC UA, the opcua_nodes_*.csv node-table format, communication base classes (BaseOpcUaClient / OpcUaClientWithSubscription), data types, and subscription/cache/reconnect behavior. Documents driver patterns for AI4MDevice, three handshake paradigms (pulse, parameter handshake, id-based), registry/graph configuration (YAML/JSON), debugging tips (KEPServerEX sim, standalone run), and a checklist for onboarding new PLC-controlled equipment.

# 添加新设备到 Uni-Lab-OS # 添加新设备到 Uni-Lab-OS
**第一步:** 使用 Read 工具读取 `docs/ai_guides/add_device.md`,获取完整的设备接入指南 本 Skill 是自包含的设备接入指南,不依赖外部文档。迁移给别人时,只复制 `.cursor/skills/add-device/SKILL.md` 即可获得核心规则、模板、验证方式和常见错误清单
该指南包含设备类别(物模型)列表、通信协议模板、常见错误检查清单等。搜索 `unilabos/devices/` 获取已有设备的实现参考。 开始实现前,仍应搜索 `unilabos/devices/` 获取同类别已有设备的接口、参数名、状态字符串和返回值风格作为参考。
---
## 接入工作流
按下面顺序推进,并在工作中维护进度:
```text
设备接入进度:
- [ ] 1. 确定设备类别(物模型)和对外单位
- [ ] 2. 确定通信协议
- [ ] 3. 收集指令协议SDK、厂商文档、寄存器表、HTTP API、用户口述
- [ ] 4. 对齐同类设备接口(搜索 unilabos/devices/
- [ ] 5. 创建驱动 unilabos/devices/<category>/<file>.py
- [ ] 6. 验证可导入、注册表扫描、启动测试
- [ ] 7. 如需要,配置实验图文件
```
## 设备类别(物模型)
优先使用已有类别。只有确实无法归类时才使用 `custom`
| 类别 ID | 说明 | 标准属性 | 标准动作 |
|---|---|---|---|
| `temperature` | 加热、冷却、温控 | `temp`, `temp_target`, `status` | `set_temperature`, `stop` |
| `pump_and_valve` | 泵、阀门、注射器 | 见子类型表 | 见子类型表 |
| `motor` | 电机、步进马达 | `position`, `status` | `enable`, `move_position`, `move_speed`, `stop` |
| `heaterstirrer` | 加热搅拌一体机 | `temp`, `stir_speed`, `status` | `set_temperature`, `stir`, `stop` |
| `balance` | 天平、称重 | `weight`, `unit`, `status` | `tare`, `read_weight` |
| `sensor` | 传感器(液位、温度等) | `value`, `level`, `status` | `read_value`, `set_threshold` |
| `liquid_handling` | 液体处理机器人 | `status`, `deck_state` | `transfer_liquid`, `aspirate`, `dispense` |
| `robot_arm` | 机械臂 | `arm_pose`, `arm_status` | `moveit_task`, `pick_and_place` |
| `workstation` | 工作站、组合设备 | `workflow_sequence`, `material_info` | `create_order`, `scheduler_start`, `scheduler_stop` |
| `virtual` | 虚拟、模拟设备 | 按模拟的真实设备定义 | 按模拟的真实设备定义 |
| `custom` | 不属于以上类别 | 用户自定义 | 用户自定义 |
`pump_and_valve` 子类型:
| 子类型 | 最小通用属性 | 最小通用动作 | 单位约定 |
|---|---|---|---|
| 注射泵syringe pump | `status`, `valve_position`, `position` | `initialize`, `set_valve_position`, `set_position`, `pull_plunger`, `push_plunger`, `stop_operation` | 体积=mL, 速度=mL/s |
| 电磁阀solenoid valve | `status`, `valve_position` | `open`, `close`, `set_valve_position` | 无 |
| 蠕动泵peristaltic pump | `status`, `speed` | `start`, `stop`, `set_speed` | 流速=mL/min |
对外暴露的属性和动作参数必须使用用户友好的物理单位mL、ul、degC、RPM 等),硬件原始值转换放在驱动内部。
## 通信协议和指令来源
先确认通信方式,再确认具体指令协议。物模型只定义设备“应该做什么”,不会告诉你硬件“具体发什么字节/请求”。
| 协议 | 常用 config 参数 | 常用依赖 | 现有抽象 |
|---|---|---|---|
| Serial (RS232/RS485) | `port`, `baudrate`, `timeout` | `pyserial` | 直接使用 `serial.Serial` |
| Modbus RTU | `port`, `baudrate`, `slave_id` | `pymodbus` | `device_comms/modbus_plc/` |
| Modbus TCP | `host`, `port`, `slave_id` | `pymodbus` | `device_comms/modbus_plc/` |
| TCP Socket | `host`, `port`, `timeout` | stdlib | 直接使用 `socket` |
| HTTP API | `url`, `token`, `timeout` | `requests` | `device_comms/rpc.py` |
| OPC UA | `url` | `opcua` | `device_comms/opcua_client/` |
| 无通信(虚拟) | 无 | 无 | 在动作中模拟行为 |
必须从以下来源之一获得指令细节:
| 来源 | 处理方式 |
|---|---|
| 现成 SDK/驱动代码 | 读取代码,提取指令逻辑,包装进 Uni-Lab-OS 类 |
| 协议文档/手册 | 解析命令、响应、校验、寄存器、错误码 |
| 用户口述 | 按描述实现指令编解码,标出不确定点 |
| 标准协议 | 使用标准实现,例如 Modbus 寄存器表、SCPI |
| 虚拟设备 | 跳过硬件通信,在动作方法中维护模拟状态 |
## 对齐已有实现(强制)
实现前必须搜索 `unilabos/devices/` 中同类别设备:
- 参数名必须与已有设备保持一致;动作方法参数名是接口契约,不要随意改成 `volume_ml``target_temp_c` 这类新名字。
- `status` 字符串值要和同类设备一致,优先使用英文稳定值,例如 `Idle``Running``Error`
- 状态属性用 `@property` + `@topic_config()` 明确声明。
- 返回值使用结构化 dict至少包含 `success`,需要给前端展示的信息放在 `message``data``error` 等字段。
## 架构选择
| 场景 | 推荐方式 |
|---|---|
| 简单设备 | 纯 Python 类 + `@device` |
| 工作站/组合设备 | `WorkstationBase` 或项目内已有工作站模式 |
| 液体处理 | `LiquidHandlerAbstract` / PyLabRobot 相关模式 |
| Modbus 设备 | 复用 `device_comms/modbus_plc/` 或项目内 Modbus 示例 |
| OPC UA 设备 | 复用 `device_comms/opcua_client/` |
| 外部独立包 | 使用 `create-device-package` skill |

## 通信实现片段
Serial 文本指令:
```python
def _send_command(self, cmd: str) -> str:
self.ser.write(f"{cmd}\r\n".encode())
return self.ser.readline().decode().strip()
```
RS-485 响应解析要先定位帧头,不要用硬编码索引直接解析原始响应:
```python
def _normalize_response(self, raw: str, start_marker: str = "/") -> str:
pos = raw.find(start_marker)
return raw[pos:] if pos >= 0 else raw
```
自定义二进制帧:
```python
def _build_frame(self, func_code: int, data: bytes) -> bytes:
frame = bytearray([0xFE, func_code]) + bytearray(data)
checksum = sum(frame[1:]) % 256
frame.append(checksum)
return bytes(frame)
```
Modbus 寄存器映射:
```python
REGISTER_MAP = {
"temp_target": {"addr": 0x000B, "scale": 10},
}
def set_temperature(self, temp: float, **kwargs) -> bool:
reg = REGISTER_MAP["temp_target"]
value = int(float(temp) * reg["scale"]) & 0xFFFF
self.client.write_register(reg["addr"], value, slave=self.slave_id)
self.data["temp_target"] = temp
return True
```
HTTP API 映射:
```python
API_MAP = {
"set_temperature": {
"method": "POST",
"endpoint": "/api/temperature",
"body_key": "target",
},
}
```
SDK 封装:
```python
from my_device_sdk import DeviceController
class MyDevice:
def __init__(self, device_id=None, config=None, **kwargs):
self.config = config or {}
self.controller = DeviceController(port=self.config.get("port", "COM1"))
```
---
## 验证
无需手写注册表 YAML。`@device` 装饰器 + AST 扫描会在启动或检查时生成注册表条目。
```bash
# 1. 模块可导入
python -c "from unilabos.devices.<category>.<file> import <ClassName>"
# 2. 启动测试
unilab -g <graph>.json
# 3. 仅检查注册表
unilab --check_mode --skip_env_check
```
仅在旧代码无 `@device`、需要覆盖特殊字段、或做 `--complete_registry` 旧设备补全时,才考虑 YAML。新设备默认不要手写 YAML。
## 图文件节点模板
实验图 JSON 中的 `class` 对应 `@device(id=...)``config` 会传入 `__init__``config` 字典:
```json
{
"id": "my_device_1",
"name": "我的设备",
"children": [],
"parent": null,
"type": "device",
"class": "my_device",
"position": {"x": 0, "y": 0, "z": 0},
"config": {
"port": "/dev/ttyUSB0",
"baudrate": 9600
},
"data": {}
}
```
工作站需要同时配置 `deck``children`
```json
{
"nodes": [
{
"id": "my_station",
"type": "device",
"class": "my_workstation",
"children": ["my_deck"],
"config": {},
"deck": {
"data": {
"_resource_child_name": "my_deck",
"_resource_type": "unilabos.resources.my_module:MyDeck"
}
}
},
{
"id": "my_deck",
"type": "deck",
"class": "MyDeckClass",
"parent": "my_station",
"config": {"type": "MyDeckClass", "setup": true}
}
]
}
```
---
## 常见错误清单
- 缺少 `@device`:设备不会被 AST 扫描发现。
- 只有 `@property` 没有 `@topic_config()`:属性不会稳定广播到 `status_types`
- `post_init` 没有 `@not_action`:会被误暴露为动作。
- `self.data = {}`:空字典会导致属性读取和 schema 初始数据不稳定,必须预填充每个状态键。
- 动作参数重命名:不要把同类设备已有的 `volume` 改成 `volume_ml`,参数名是接口契约。
- `status` 使用中文或临时文本:前端和工作流依赖稳定英文状态值。
- async 方法中使用 `time.sleep()`:应使用 `await self._ros_node.sleep(seconds)`
- 硬编码串口响应索引RS-485 响应前可能有噪声字节,应先定位帧头。
- 把硬件寄存器单位暴露给用户:对外使用物理单位,驱动内部做 scale 转换。

## 0. 总览:一台 PLC 设备从硬件到云端的链路
```
PLC西门子 / 倍福 / 三菱 / 汇川 / 国产 PLC ...
│ 各家 PLC 私有协议S7 / Modbus / EtherCAT ...
┌──────────┴──────────┐
│ OPC UA Server │ ← 统一在 PLC 侧或独立网关上配置

│ OPC UA over TCP标准协议
┌──────────┴──────────┐

```
**统一约定**:所有 PLC 设备**只暴露 OPC UA 接口**给 Uni-LabPC 端不直接处理 S7 / Modbus 等底层协议。
这是 Uni-Lab 在工站类设备上的 PLC 通信标准。
---
## 1. 为什么选 OPC UA 作为标准?
| 维度 | 自研 TCP/串口协议 | Modbus | **OPC UA** |
|---|---|---|---|
| 厂家无关 | ✗ | 部分 | **✓** |
| 自带类型系统 | ✗ | ✗(裸寄存器) | **Boolean/Int16/Float...** |
| 命名空间 / 节点树 | ✗ | ✗(地址=魔数) | **✓(带名字、可分组)** |
| 订阅推送 | ✗ | ✗ | **DataChange Notification** |
| 鉴权 / 加密 | 自己造 | ✗ | **✓** |
| 与 PLC 工程师沟通成本 | 高 | 中 | **低(按变量名沟通)** |
实际接入时PLC 工程师只需要在 PLC 侧把约定的"上位通讯变量"暴露到 OPC UA Server
我们在 PC 侧就能用 `节点名 + 数据类型` 直接读写,不用管底层是 S7 还是 Modbus。
---
## 2. 节点表标准:`opcua_nodes_xxx.csv`
PLC 侧暴露的所有变量统一**用一张 CSV 表**描述,这是 PC 端和 PLC 端**唯一的接口契约**。
位置示例:`unilabos/devices/workstation/AI4M/opcua_nodes_AI4M.csv`
### 2.1 列定义
| 列名 | 是否必填 | 说明 |
|---|---|---|
| `Name` | ✅ | 节点名PLC 工程师在 PLC 项目中真实使用的变量名,通常是中文/原始名) |
| `EnglishName` | 推荐 | 英文别名,**PC 端代码全部用这个名字**调用 |
| `NodeType` | ✅ | `VARIABLE`(变量)或 `METHOD`方法AI4M 全部用变量 |
| `DataType` | ✅ | `BOOLEAN` / `INT16` / `INT32` / `FLOAT` / `DOUBLE` / `STRING` ... |
| `NodeLanguage` | 推荐 | `Chinese` / `English`,配合 `EnglishName` 做映射 |
| `NodeId` | ✅ | OPC UA 标准 NodeId格式 `ns=<namespace>;s=<string>``ns=<n>;i=<int>` |
### 2.2 真实样例(节选自 `opcua_nodes_AI4M.csv`
| Name | EnglishName | NodeType | DataType | NodeLanguage | NodeId |
|---|---|---|---|---|---|
| 机器人空闲 | `robot_ready` | VARIABLE | BOOLEAN | Chinese | `ns=4;s=上位通讯变量\|机器人空闲` |
| 机器人取烧杯编号 | `robot_pick_beaker_id` | VARIABLE | INT16 | Chinese | `ns=4;s=上位通讯变量\|机器人取烧杯编号` |
| 检测1请求参数 | `station_1_request_params` | VARIABLE | BOOLEAN | Chinese | `ns=4;s=上位通讯变量\|检测1请求参数` |
| 检测1工艺完成 | `station_1_process_complete` | VARIABLE | BOOLEAN | Chinese | `ns=4;s=上位通讯变量\|检测1工艺完成` |
| 磁力搅拌参数设置_C[0].搅拌速度 | `mag_stirrer_c0_stir_speed` | VARIABLE | INT16 | Chinese | `ns=4;s=上位通讯变量\|磁力搅拌参数设置_C[0].搅拌速度` |
| 报警复位 | `alarm_reset` | VARIABLE | BOOLEAN | Chinese | `ns=4;s=上位通讯变量\|报警复位` |
### 2.3 设计规范(必读)
1. **命名按"角色-编号-属性"分层**,便于代码批量寻址:
- `mag_stirrer_c{0..4}_stir_speed`(搅拌仪 0~4 的搅拌速度)
- `station_{1..3}_process_complete`(检测站 1~3 的完成信号)
- `robot_rack_pick_beaker_{1..5}_complete`(取烧杯 1~5 的完成信号)
这样在驱动里可以直接 `f"mag_stirrer_c{idx}_stir_speed"` 拼出节点名。
2. **数据类型与 PLC 侧严格一致**
- `BOOL``BOOLEAN``INT/WORD``INT16/UINT16``DINT``INT32``REAL``FLOAT`
- 类型不一致会触发 `BadTypeMismatch`,写入失败。
3. **NodeId 必须从 PLC 工程或 OPC UA Server 中导出**,不要自己拼。
常见格式:
- 西门子 1500`ns=4;s=上位通讯变量|<变量名>`
- 倍福 TwinCAT`ns=4;s=PLC1.MAIN.<变量名>`
- KEPServerEX`ns=2;s=Channel1.Device1.<Tag>`
4. **每个工站一个独立 CSV**,不要共用。
AI4M 中真机用 `opcua_nodes_AI4M.csv`,仿真用 `opcua_nodes_AI4M_sim.csv`
---
## 3. 通信基类架构
文件:`unilabos/devices/workstation/AI4M/base_opcua_client.py`
整个通信层分两层:
```
BaseOpcUaClient # 最小可用:连接 + 节点注册 + 读写 + 方法调用
│ 继承
OpcUaClientWithSubscription # 生产可用:+ 订阅推送 + 缓存 + 自动重连
│ 继承
AI4MDevice # 业务驱动:在它之上写设备动作函数
```
### 3.1 `BaseOpcUaClient` 核心能力
```python
class BaseOpcUaClient(UniversalDriver):
client: Optional[Client] = None
_node_registry: Dict[str, OpcUaNodeBase] = {} # name -> Variable/Method
_name_mapping: Dict[str, str] = {} # 英文名 -> 中文名
_reverse_mapping: Dict[str, str] = {} # 中文名 -> 英文名
_found_node_objects: Dict[str, Any] = {} # 缓存 ua.Node 用于订阅
@classmethod
def load_csv(cls, file_path) -> Tuple[List[OpcUaNode], dict, dict]: ...
def register_node_list(self, node_list) -> "BaseOpcUaClient": ...
def use_node(self, name) -> OpcUaNodeBase: ...
def read_node(self, node_name: str) -> str: ... # 返回 JSON
def write_node(self, json_input: str) -> str: ...
def call_method(self, node_name, *args) -> Tuple[Any, bool]: ...
```
它做的事情可以归纳为四步:
1. **`load_csv`**:读取节点表,建立 `Name ↔ EnglishName` 双向映射。
2. **`register_node_list`**:把节点登记进 `_variables_to_find` 待查找列表。
3. **`_connect``_find_nodes`**:连上 OPC UA 后,按 `NodeId` 把每个节点解析成 `Variable` / `Method` 对象,放进 `_node_registry`
4. **`use_node(name)`**:业务代码取节点的唯一入口,**支持中英文混用**,找不到会自动重试一次。
### 3.2 `OpcUaClientWithSubscription` 增强能力
`BaseOpcUaClient` 基础上提供三个生产环境必备的能力:
#### a) 订阅缓存(高频读零开销)
```python
def _setup_subscriptions(self):
self._subscription = self.client.create_subscription(
self._subscription_interval, # 默认 500ms
SubscriptionHandler(self),
)
for node_name, node in self._node_registry.items():
if node.type == NodeType.VARIABLE and node.node_id:
handle = self._subscription.subscribe_data_change(ua_node)
self._subscription_handles[node_name] = handle
```
当 PLC 侧变量变化时,`datachange_notification` 回调会把新值写进 `self._node_values[name]`
后续 `get_node_value` 优先读缓存——**业务代码可以放心地写 `while not self.get_node_value(...): time.sleep(1)` 而不用担心 OPC UA 频繁请求**。
#### b) 智能缓存的 `get_node_value`
```python
def get_node_value(self, name, use_cache=True, force_read=False):
# 1. 中英文名归一化
chinese_name = self._name_mapping.get(name, name)
# 2. force_read=True 强制透传到 OPC UA Server
if force_read: ...
# 3. 命中订阅推送 → 直接返回缓存
# 4. 命中按需读 + 未过期cache_timeout=5s→ 返回缓存
# 5. 否则发起 read 并更新缓存
```
#### c) 连接监控 + 自动重连
后台线程每 30s 调一次 `client.get_namespace_array()` 探活,断线则自动 `disconnect → connect → 重新订阅`,最多重试 5 次。
### 3.3 数据类型 / 节点类型
`unilabos/device_comms/opcua_client/node/uniopcua.py`
```python
class DataType(Enum):
BOOLEAN = VariantType.Boolean
INT16 = VariantType.Int16
INT32 = VariantType.Int32
FLOAT = VariantType.Float
STRING = VariantType.String
# ...
class NodeType(Enum):
VARIABLE = NodeClass.Variable
METHOD = NodeClass.Method
OBJECT = NodeClass.Object
```
`Variable.write()` 内部会按 `DataType` 做强制类型转换,
所以 CSV 里的 `DataType` 列就是"PC 端转换写入值的类型说明书"。
---
## 4. 编写设备驱动:以 `AI4MDevice` 为例
文件:`unilabos/devices/workstation/AI4M/AI4M.py`
### 4.1 继承通信基类,最小骨架
```python
from typing import Optional
from unilabos.devices.workstation.AI4M.base_opcua_client import OpcUaClientWithSubscription
class AI4MDevice(OpcUaClientWithSubscription):
def __init__(
self,
url: str, # opc.tcp://192.168.1.10:4840
deck: Optional[AI4M_deck] = None, # 物料台面(资源树)
csv_path: str = None, # 节点表 CSV
username: str = None,
password: str = None,
use_subscription: bool = True,
cache_timeout: float = 5.0,
subscription_interval: int = 500,
*args, **kwargs,
):
super().__init__(
url=url, username=username, password=password,
use_subscription=use_subscription,
cache_timeout=cache_timeout,
subscription_interval=subscription_interval,
*args, **kwargs,
)
# 物料台面初始化(见教程 4. 物料系统)
self.deck = deck or AI4M_deck(setup=True)
self._robot_lock = threading.Lock()
# 关键:加载节点表
if csv_path:
self.load_nodes_from_csv(csv_path)
```
`load_nodes_from_csv` 会一次性完成:解析 CSV → 注册节点 → 解析 NodeId → 建立订阅,
**之后整个驱动都通过 `self.get_node_value(name)` / `self.set_node_value(name, value)` 操作 PLC**
### 4.2 PLC 通信的核心模式握手协议Handshake
PLC 编程的本质是"扫描周期 + 状态机"PC 端**绝对不能用 fire-and-forget 的方式发指令**。
和 PLC 配合的标准模式是 **"PC 写指令 → PC 等待 PLC 回执 → PC 复位指令"**。
AI4M 中所有 `trigger_*` 函数都遵循以下三种握手范式之一:
#### 范式 A脉冲触发 + 完成信号(最常用)
```python
def trigger_init(self) -> dict:
# ① 复位上一轮残留
self.set_node_value("alarm_reset", True); time.sleep(1.0)
self.set_node_value("alarm_reset", False)
self.set_node_value("manual_auto_switch", False)
# ② 等待 PLC 退出自动模式
while self.get_node_value("auto_mode"):
time.sleep(1.0)
# ③ 发起初始化脉冲True → False
self.set_node_value("initialize", True); time.sleep(1.0)
self.set_node_value("initialize", False)
# ④ 等待 PLC 给出完成信号
while not self.get_node_value("init finished"):
time.sleep(1.0)
return {"message": "设备初始化完成"}
```
要点:
- **"PC 写一个 BOOL 拉高再拉低"** 模拟脉冲PLC 用上升沿触发动作。
- **`get_node_value` 要在 while 循环里轮询**,配合订阅缓存基本无压力。
- **每个动作必须有"开始"和"完成"两个独立的 BOOL 节点**,不能复用。
#### 范式 B参数下发 + 请求/已执行/完成 三步握手(带数据的工艺)
```python
def trigger_station_process(self, station_id: int, mag_stir_speed: int, ...):
request_node = f"station_{station_id}_request_params"
params_received_node = f"station_{station_id}_params_received"
start_node = f"station_{station_id}_start"
complete_node = f"station_{station_id}_process_complete"
# ① PC 复位三个状态位(避免上一轮影响)
self._reset_station_process_flags(station_id)
# ② 等 PLC 主动请求参数PLC 准备好了才接收)
while not self.get_node_value(request_node):
time.sleep(1.0)
# ③ PC 下发参数注意PLC 内部数组是 0-basedPC 暴露给用户是 1-based
station_idx = station_id - 1
self.set_node_value(f"mag_stirrer_c{station_idx}_stir_speed", mag_stir_speed)
self.set_node_value(f"mag_stirrer_c{station_idx}_heat_temp", mag_stir_heat_temp)
self.set_node_value(f"mag_stirrer_c{station_idx}_time_set", mag_stir_time_set)
self.set_node_value(f"syringe_pump_{station_idx}_abs_position_set", syringe_pump_abs_pos)
# ④ PC 通知 PLC "参数已就绪",等 PLC 回复"已执行"
self.set_node_value(start_node, True)
while not self.get_node_value(params_received_node):
time.sleep(1.0)
# ⑤ 等 PLC 完成整个工艺
while not self.get_node_value(complete_node):
time.sleep(5.0)
self.set_node_value(start_node, False) # 复位,方便下一轮
return {"station_id": station_id, "message": "..."}
```
四个状态位的语义:
| 信号 | 方向 | 含义 |
|---|---|---|
| `station_X_request_params` | **PLC → PC** | "我准备好了,把参数给我" |
| `station_X_start` | **PC → PLC** | "参数我已经写好了,开干" |
| `station_X_params_received` | **PLC → PC** | "参数我已经吃下了" |
| `station_X_process_complete` | **PLC → PC** | "工艺已经做完" |
**这是 PLC 通信教科书级别的标准范式**,所有带数据下发的动作都建议照抄。
#### 范式 C编号下发 + 编号对应的完成信号(多目标互锁)
```python
def trigger_robot_pick_beaker(self, pick_beaker_id: int, place_station_id: int = None, ...):
# ① 等机器人空闲(互锁)
while not self.get_node_value("robot_ready"):
time.sleep(1.0)
# ② 阶段一:下发"取哪一杯"编号 + 等"取这一杯完成"
pick_complete_node = f"robot_rack_pick_beaker_{pick_beaker_id}_complete"
self.set_node_value("robot_pick_beaker_id", pick_beaker_id)
while not self.get_node_value(pick_complete_node):
time.sleep(1.0)
# ③ 阶段二:下发"放到哪个工站"编号 + 等"放完成"
place_complete_node = f"robot_place_station_{place_station_id}_complete"
self._reset_station_process_flags(place_station_id)
self.set_node_value("robot_place_station_id", place_station_id)
while not self.get_node_value(place_complete_node):
time.sleep(1.0)
```
要点:
- **同一个动作的多个目标用"编号变量 + 编号对应的完成信号"实现**,不要每个目标都开一个开始位。
- **配合 Python 端 `threading.Lock()` 做软互锁**,避免多个线程争抢机器人。
- **每个阶段有独立的完成信号**,串行等待,不能合并。
### 4.3 一些容易踩坑的细节
1. **节点名映射**
`set_node_value("alarm_reset", True)` 实际写入的是 CSV 中文名 `报警复位`
`get_node_value` 同理。**业务代码全部用 EnglishName**,不要直接用中文。
2. **PLC 数组索引和 PC 不一致**
AI4M 里 PC 暴露 `station_id ∈ {1, 2, 3}`,但 PLC 内部数组是 `C[0..2]`
驱动里要做 `station_idx = station_id - 1`**这种映射只在驱动层做一次**
不要让上层registry / 实验记录本)感知。
3. **订阅模式下 BOOL 节点的边沿同步**
订阅有 ~500ms 延迟。如果你刚 `set_node_value(x, True)` 就立刻 `get_node_value(x)`
读到的可能还是 `False`(订阅还没推回来)。
解决方案:**写完后用 `force_read=True` 透传一次** 或加一段 `time.sleep`
4. **永远不要忘记复位**
`start` 拉 True 后必须有地方拉回 False否则下一轮 PLC 上升沿不触发。
AI4M 在 `_reset_station_process_flags` 中统一做:
```python
def _reset_station_process_flags(self, station_id: int) -> None:
self.set_node_value(f"station_{station_id}_process_complete", False)
self.set_node_value(f"station_{station_id}_start", False)
self.set_node_value(f"station_{station_id}_params_received", False)
```
5. **耗时长的等待 sleep 加大**
工艺等待用 `time.sleep(5.0)`,机器人等待用 `time.sleep(1.0)`,初始化等待 `time.sleep(1.0)`
不要全部用 0.1s 轮询,会把日志刷爆。
---
## 5. 把驱动接到 Uni-LabRegistry + Graph
### 5.1 Registry YAML动作 schema
文件:`unilabos/registry/devices/AI4M_station.yaml`
```yaml
AI4M_station:
category: [AI4M_station]
class:
module: unilabos.devices.workstation.AI4M.AI4M:AI4MDevice # ← 入口类
type: python
action_value_mappings:
auto-trigger_init:
schema:
description: 设备初始化...
properties:
goal: { properties: {}, required: [], type: object }
result:
properties: { message: { type: string } }
required: [message]
type: object
type: object
type: UniLabJsonCommand
auto-trigger_station_process:
always_free: true
schema:
description: 执行检测工艺流程
properties:
goal:
properties:
station_id: { type: integer, description: 检测编号 1-3 }
mag_stir_stir_speed: { type: integer }
mag_stir_heat_temp: { type: integer }
mag_stir_time_set: { type: integer }
syringe_pump_abs_position_set:{ type: integer }
required: [station_id, mag_stir_stir_speed, mag_stir_heat_temp,
mag_stir_time_set, syringe_pump_abs_position_set]
type: object
result: { ... }
type: UniLabJsonCommand
init_param_schema:
config:
type: object
required: [url]
properties:
url: { type: string, description: OPC UA 服务器地址 }
csv_path: { type: string, description: 节点配置 CSV 路径 }
deck: { type: string, description: 资源树配置 }
username: { type: string }
password: { type: string }
use_subscription: { type: boolean, default: true }
cache_timeout: { type: number, default: 5.0 }
subscription_interval: { type: integer, default: 500 }
```
规则总结:
- `class.module` 指向驱动类(`module:ClassName`)。
- `action_value_mappings` 中的 key 形如 `auto-<方法名>`,对应驱动里的同名 Python 方法。
- `schema.goal` 自动转成 ROS2 Action 的 goal 消息,`schema.result` 转 result。
- `init_param_schema.config` 对应 `__init__` 的入参,**所有需要现场改的参数都要列出来**(最重要的就是 `url` 和 `csv_path`)。
- `always_free: true` 表示该动作不占用工站独占锁(多检测站可并发执行)。
### 5.2 Graph JSON实例化
文件:`unilabos/devices/workstation/AI4M/AI4M.json`
```json
{
"nodes": [
{
"id": "AI4M_station",
"name": "AI4M_station",
"type": "device",
"class": "AI4M_station",
"children": ["AI4M_deck"],
"parent": null,
"config": {
"url": "opc.tcp://192.168.1.10:4840",
"csv_path": "opcua_nodes_AI4M.csv",
"deck": {
"data": {
"_resource_child_name": "AI4M_deck",
"_resource_type": "unilabos.devices.workstation.AI4M.decks:AI4M_deck"
}
}
}
},
{
"id": "AI4M_deck",
"type": "deck",
"class": "AI4M_deck",
"parent": "AI4M_station",
"config": { "type": "AI4M_deck" }
}
]
}
```
要点:
- `class` 必须和 Registry YAML 的顶层 key 完全一致(`AI4M_station`)。
- `config` 字段**逐字传给驱动 `__init__`**,所以 Graph JSON = "现场参数表"。
- 多套相同设备时拷贝一份,把 `id` / `url` 改掉即可(参考 `AI4M002_station`)。
### 5.3 启动命令(来自 `start.md`
```cmd
# 真机
python unilabos/app/main.py -g unilabos/devices/workstation/AI4M/AI4M.json `
--ak <ak> --sk <sk> --upload_registry --addr <api_url> --disable_browser
# 仿真KEPServerEX 跑在本机 49320 端口)
python unilabos/app/main.py -g unilabos/devices/workstation/AI4M/AI4Msim.json `
--ak <ak> --sk <sk> --upload_registry --disable_browser
```
`--upload_registry` 会把 `AI4M_station.yaml` 的 schema 上传到云端,
之后实验记录本就能看到所有 `auto-*` 动作。
---
## 6. 调试方法
### 6.1 用 KEPServerEX 仿真 PLC
不带 PLC 的开发机上,可以用 KEPServerEX或 `python-opcua` 自建 server模拟。
AI4M 提供了一份仿真节点表 `opcua_nodes_AI4M_sim.csv`**只改 NodeId 不改语义**
所以驱动代码无需任何改动即可在本机调试。
### 6.2 单独跑驱动(不开 ROS
在驱动文件末尾的 `if __name__ == '__main__':` 段:
```python
if __name__ == '__main__':
A4 = AI4MDevice(
url="opc.tcp://192.168.1.10:4840",
csv_path="opcua_nodes_AI4M.csv",
)
A4.trigger_init()
print("初始化完成")
A4.trigger_robot_pick_beaker(1, 1)
```
**新动作上线前一定要在这里裸跑一遍**,确认握手时序正确,再往上接 ROS。
### 6.3 看日志判断卡在哪
`base_opcua_client.py` 的日志已经覆盖了所有关键节点:
```
✓ 客户端已连接!
✓ 找到变量节点: 'robot_ready', NodeId: ns=4;s=...
✓ 已订阅节点: robot_ready
✓ 节点查找完成:所有 142 个节点均已找到
```
如果看到 `⚠ 以下 N 个节点未找到`**99% 是 CSV 里的 NodeId 写错了**,回去对一下 PLC 工程导出的 NodeId。
### 6.4 检查节点是否能直接读写
```python
# 透传读,绕过订阅缓存
A4.get_node_value("robot_ready", force_read=True)
# 直接读 JSON 形式(适合从 HTTP/调试面板调)
A4.read_node("robot_ready")
# 写
A4.set_node_value("alarm_reset", True)
A4.write_node('{"node_name": "alarm_reset", "value": false}')
```

## 7. 接入新 PLC 设备的 Checklist
接到一台新工站时,按下面顺序做就能保证不漏:
- [ ] 1. 让 PLC 工程师把上位通讯变量整理到 OPC UA Server导出 NodeId 清单。
- [ ] 2. 在 `unilabos/devices/workstation/<设备名>/` 下新建目录,复制 `AI4M/base_opcua_client.py` 不动。
- [ ] 3. 整理 `opcua_nodes_<设备名>.csv`6 列填齐,并补上 `EnglishName`。
- [ ] 4. 在该目录写设备驱动 `<设备名>.py`,继承 `OpcUaClientWithSubscription`
- [ ] `__init__` 调用 `super().__init__` + `self.load_nodes_from_csv(csv_path)`。
- [ ] 每个动作函数用范式 A/B/C 写握手协议。
- [ ] 每个动作函数都返回 `dict`,至少含 `message` 字段。
- [ ] 5. 在 `unilabos/registry/devices/` 下新建 `<设备名>_station.yaml`,配置 `init_param_schema` 和 `action_value_mappings`。
- [ ] 6. 在该目录新建 `<设备名>.json`Graph填好 `url` 和 `csv_path`。
- [ ] 7. 用 `if __name__ == '__main__':` 单独跑驱动确认握手 OK。
- [ ] 8. 用 `python unilabos/app/main.py -g <Graph> --upload_registry ...` 上线,到实验记录本下发动作回归。
