+# 梅特勒天平 ROS2 使用指南 / Mettler Toledo Balance ROS2 User Guide
+
+## 概述 / Overview
+
+梅特勒托利多XPR/XSR天平驱动支持通过ROS2动作进行操作，包括去皮、清零、读取重量等功能。
+
+The Mettler Toledo XPR/XSR balance driver supports operations through ROS2 actions, including tare, zero, weight reading, and other functions.
+
+## 主要功能 / Main Features
+
+### 1. 去皮操作 / Tare Operation (`tare`)
+
+- **功能 / Function**: 执行天平去皮操作 / Perform balance tare operation
+- **输入 / Input**: `{"immediate": bool}` - 是否立即去皮 / Whether to tare immediately
+- **输出 / Output**: `{"return_info": str, "success": bool}`
+
+### 2. 清零操作 / Zero Operation (`zero`)
+
+- **功能 / Function**: 执行天平清零操作 / Perform balance zero operation
+- **输入 / Input**: `{"immediate": bool}` - 是否立即清零 / Whether to zero immediately
+- **输出 / Output**: `{"return_info": str, "success": bool}`
+
+### 3. 读取重量 / Read Weight (`read` / `get_weight`)
+
+- **功能 / Function**: 读取当前天平重量 / Read current balance weight
+- **输入 / Input**: 无参数 / No parameters
+- **输出 / Output**: `{"return_info": str, "success": bool}` - 包含重量信息 / Contains weight information
+
+
+
+## 使用方法 / Usage Methods
+
+### ROS2命令行使用 / ROS2 Command Line Usage
+
+### 1. 去皮操作 / Tare Operation
+
+```bash
+ros2 action send_goal /devices/BALANCE_STATION/send_cmd unilabos_msgs/action/SendCmd "{
+  command: '{\"command\": \"tare\", \"params\": {\"immediate\": false}}'
+}"
+```
+
+### 2. 清零操作 / Zero Operation
+
+```bash
+ros2 action send_goal /devices/BALANCE_STATION/send_cmd unilabos_msgs/action/SendCmd "{
+  command: '{\"command\": \"zero\", \"params\": {\"immediate\": false}}'
+}"
+```
+
+### 3. 读取重量 / Read Weight
+
+```bash
+ros2 action send_goal /devices/BALANCE_STATION/send_cmd unilabos_msgs/action/SendCmd "{
+  command: '{\"command\": \"read\"}'
+}"
+```
+
+
+### 4. 推荐的去皮读取流程 / Recommended Tare and Read Workflow
+
+**步骤1: 去皮操作 / Step 1: Tare Operation**
+```bash
+# 放置空容器后执行去皮 / Execute tare after placing empty container
+ros2 action send_goal /devices/BALANCE_STATION/send_cmd unilabos_msgs/action/SendCmd "{
+  command: '{\"command\": \"tare\", \"params\": {\"immediate\": false}}'
+}"
+```
+
+**步骤2: 读取净重 / Step 2: Read Net Weight**
+```bash
+# 添加物质后读取净重 / Read net weight after adding substance
+ros2 action send_goal /devices/BALANCE_STATION/send_cmd unilabos_msgs/action/SendCmd "{
+  command: '{\"command\": \"read\"}'
+}"
+```
+
+**优势 / Advantages**:
+- 可以在去皮和读取之间进行确认 / Can confirm between taring and reading
+- 更好的错误处理和调试 / Better error handling and debugging
+- 操作流程更加清晰 / Clearer operation workflow
+
+
+
+## 命令格式说明 / Command Format Description
+
+所有命令都使用JSON格式，包含以下字段 / All commands use JSON format with the following fields：
+
+```json
+{
+  "command": "命令名称 / Command name",
+  "params": {
+    "参数名 / Parameter name": "参数值 / Parameter value"
+  }
+}
+```
+
+**注意事项 / Notes：**
+1. JSON字符串需要正确转义引号 / JSON strings need proper quote escaping
+2. 布尔值使用小写（true/false）/ Boolean values use lowercase (true/false)
+3. 如果命令不需要参数，可以省略`params`字段 / If command doesn't need parameters, `params` field can be omitted
+
+## 返回结果 / Return Results
+
+所有命令都会返回包含以下字段的结果 / All commands return results with the following fields：
+
+- `success`: 布尔值，表示操作是否成功 / Boolean value indicating operation success
+- `return_info`: 字符串，包含操作结果的详细信息 / String containing detailed operation result information
+
+## 成功执行示例 / Successful Execution Example
+
+以下是一个成功执行读取重量命令的示例 / Here is an example of successfully executing a weight reading command：
+
+```bash
+ros2 action send_goal /devices/BALANCE_STATION/send_cmd unilabos_msgs/action/SendCmd "{
+  command: '{\"command\": \"read\"}'
+}"
+```
+
+**成功返回结果 / Successful Return Result：**
+```
+Waiting for an action server to become available...
+Sending goal:
+     command: '{"command": "read"}'
+
+Goal accepted :)
+
+Result:
+    success: True
+    return_info: Weight: 0.24866 Milligram
+
+Goal finished with status: SUCCEEDED
+```
+

+
+### 3. 方法列表查询 / Method List Query (`get_methods`)
+
+- **功能 / Function**: 获取设备支持的所有方法列表 / Get all method lists supported by the device
+- **输出 / Output**: 方法列表字典 / Method list dictionary
+
+### 4. 放盘操作 / Tray Operation (`put_tray`)
+

+- **输出 / Output**: 版本信息字典 / Version information dictionary
+
+## 使用方法 / Usage Methods
+
+### ROS2命令行使用 / ROS2 Command Line Usage
+
+### 1. 查询设备状态 / Query Device Status
+
+```bash
+ros2 action send_goal /devices/ZHIDA_GCMS_STATION/get_status unilabos_msgs/action/EmptyIn "{}"
+```
+
+### 2. 查询方法列表 / Query Method List
+
+```bash
+ros2 action send_goal /devices/ZHIDA_GCMS_STATION/get_methods unilabos_msgs/action/EmptyIn "{}"
+```
+
+### 3. 启动分析 / Start Analysis
+
+使用CSV文件启动分析 / Start analysis using CSV file:
+```bash
+ros2 action send_goal /devices/ZHIDA_GCMS_STATION/start_with_csv_file unilabos_msgs/action/StrSingleInput "{string: 'D:/path/to/your/samples.csv'}"
+```
+
+ros2 action send_goal /devices/ZHIDA_GCMS_STATION/start_with_csv_file unilabos_msgs/action/StrSingleInput "{string: 'd:/UniLab/Uni-Lab-OS/unilabos/devices/zhida_gcms/zhida_gcms-test_3.csv'}"
+
+使用Base64编码数据启动分析 / Start analysis using Base64 encoded data:
+```bash
+ros2 action send_goal /devices/ZHIDA_GCMS_STATION/start unilabos_msgs/action/StrSingleInput "{string: 'U2FtcGxlTmFtZSxBY3FNZXRob2QsUmFja0NvZGUsVmlhbFBvcyxTbXBsSW5qVm9sLE91dHB1dEZpbGU...'}"
+```
+ros2 action send_goal /devices/ZHIDA_GCMS_STATION/start unilabos_msgs/action/StrSingleInput "{string: 'U2FtcGxlTmFtZSxBY3FNZXRob2QsUmFja0NvZGUsVmlhbFBvcyxTbXBsSW5qVm9sLE91dHB1dEZpbGUKU2FtcGxlMDAxLDIwMjUwNjA0LXRlc3QsUmFjayAxLDEsMSwvQ2hyb21lbGVvbkxvY2FsL++/veixuO+/vcSyxLzvv73vv73vv73vv73vv73vv73vv73vv73vv70vMjAyNTA2MDQK'}"
+
+### 4. 放盘操作 / Tray Operation
+
+**注意 / Note**: 放盘操作是特殊场景下使用的功能，比如机械臂比较短需要让开位置，或者盘支架是可移动的时候，这个指令让进样器也去做相应动作。在当前配置中，空间足够，不需要这个额外的控制组件。
+
+**Note**: The tray operation is used in special scenarios, such as when the robotic arm is relatively short and needs to make room, or when the tray bracket is movable, this command makes the injector perform corresponding actions. In the current configuration, the space is sufficient and this additional control component is not needed.
+
+准备样品托盘 / Prepare sample tray:
+```bash
+ros2 action send_goal /devices/ZHIDA_GCMS_STATION/put_tray unilabos_msgs/action/EmptyIn "{}"
+```
+
+### 5. 停止运行 / Stop Operation
+
+中止当前分析任务（注意！运行中发现任务运行中止，需要人工在InLab Solution 二次点击确认）/ Abort current analysis task (Note! If task abortion is detected during operation, manual confirmation is required by clicking twice in InLab Solution):
+```bash
+ros2 action send_goal /devices/ZHIDA_GCMS_STATION/abort unilabos_msgs/action/EmptyIn "{}"
+```
+
+### 6. 获取版本信息 / Get Version Information
+
+查询设备版本 / Query device version:
+```bash
+ros2 action send_goal /devices/ZHIDA_GCMS_STATION/get_version unilabos_msgs/action/EmptyIn "{}"
+```
+
+### Python代码使用 / Python Code Usage
+
+```python
+from unilabos.devices.zhida_gcms.zhida import ZhidaClient
+
+# 初始化客户端 / Initialize client
+client = ZhidaClient(host='192.168.3.184', port=5792)
+client.connect()
+
+# 使用CSV文件启动分析 / Start analysis using CSV file
