|
||
|
||
## 二、系统需求分析
|
||
### 2.1 运行环境需求
|
||
- **硬件环境**：RK3568嵌入式开发板（支持Linux系统、文件系统、SQLite数据库）
|
||
- **软件环境**：Linux操作系统、Python 3.8、**FastAPI**、Uvicorn ASGI服务、SQLite数据库、JSON文件存储支持
|
||
- **交互环境**：Web浏览器（支持WebSocket、动态数据渲染、按钮交互、表格/波形展示）
|
||
|
||
### 2.2 功能需求
|
||
#### 2.2.1 参数配置管理功能
|
||
实现测控设备全维度参数配置，配置项支持**JSON文件本地存储**，关键参数通过接口下发至C语言嵌入式程序，具体配置项如下：
|
||
1. **基础设备配置**
|
||
- 设备软件版本信息展示与配置
|
||
- 通讯参数设置：串口、网口参数配置
|
||
- 操作密码设置：支持密码修改、本地JSON文件存储
|
||
2. **装置通道配置**
|
||
- AI通道设置：模拟量输入配置、信号类型、所属线路、数据阈值
|
||
- AO通道设置：模拟量输出配置
|
||
- 定值设置：电压/电流/功率等超限限值、检测延时、报警输出配置
|
||
3. **系统管理配置**
|
||
- 对时设置：参数实时下发嵌入式程序
|
||
- 灯光设置：屏幕亮度、屏保时间，参数实时下发嵌入式程序
|
||
|
||
#### 2.2.2 实时数据动态显示功能
|
||
1. **数据读取周期**：间隔**0.5秒**从C语言控制系统读取实时数据
|
||
2. **数据类型**：模拟量、开关量、AI采集数据
|
||
3. **推送方式**：**WebSocket主动推送**至Web界面，动态刷新展示
|
||
4. **存储规则**：动态数据仅内存缓存，**不保存到本地**
|
||
|
||
#### 2.2.3 设备状态实时监测功能
|
||
从嵌入式系统动态读取设备状态，Web界面实时展示：
|
||
- 装置自检状态（正常/异常）
|
||
- 网络1状态、网络2状态
|
||
- 串口1状态、串口2状态
|
||
|
||
#### 2.2.4 报警事件管理功能
|
||
1. **报警数据采集**：实时获取嵌入式设备报警事件
|
||
2. **数据存储**：报警事件保存至**SQLite数据库**
|
||
3. **展示方式**：**WebSocket实时推送**报警至Web界面，支持弹窗提醒+历史查询
|
||
|
||
### 2.3 数据交互需求
|
||
#### 2.3.1 上行数据（嵌入式系统→Python服务）
|
||
- 实时数据：0.5秒/次，模拟量、开关量、AI采集数据
|
||
- 状态数据：装置自检、网络、串口状态
|
||
- 报警数据：实时报警事件数据
|
||
|
||
#### 2.3.2 下行数据（Python服务→嵌入式系统）
|
||
- 配置数据：设备参数、通道配置、定值、对时、灯光参数
|
||
- 控制指令：开关量分/合控制信号
|
||
|
||
### 2.4 数据存储需求
|
||
1. **JSON文件存储**：设备版本、通讯参数、密码、AI/AO配置、定值配置等**非实时参数**
|
||
2. **SQLite数据库**：报警事件数据（支持历史查询）
|
||
3. **动态数据**：仅内存缓存，不持久化存储
|
||
|
||
### 2.5 性能需求
|
||
1. **数据刷新率**：实时数据读取与WebSocket推送间隔≤0.5秒
|
||
2. **响应速度**：参数配置下发、开关控制指令响应时间≤1秒
|
||
3. **稳定性**：7×24小时连续运行
|
||
4. **兼容性**：适配RK3568硬件，兼容嵌入式C程序接口
|
||
|
||
### 2.6 通信服务需求
|
||
1. **HTTP服务**：基于FastAPI提供**RESTful API**，用于参数配置、状态查询、报警查询、控制指令
|
||
2. **WebSocket服务**：基于FastAPI提供双工通信，用于**实时数据、报警数据主动推送**至Web界面
|
||
|
||
## 三、系统架构设计
|
||
### 3.1 总体架构
|
||
系统采用**分层架构 + 前后端分离**设计，从下到上分为：
|
||
**硬件层 → 嵌入式C程序层 → Python FastAPI服务层 → Web界面层**
|
||
|
||
```
|
||
Web界面层（HTML/CSS/JS）
|
||
↓↑（HTTP + WebSocket）
|
||
Python FastAPI服务层（RESTful接口 + WebSocket推送 + 数据处理）
|
||
↓↑（内部进程/核间通讯）
|
||
嵌入式C程序层（数据采集 + 控制执行）
|
||
↓
|
||
硬件层（RK3568 + 测控硬件 + 通讯模块）
|
||
```
|
||
|
||
### 3.2 分层详细设计
|
||
#### 3.2.1 硬件层
|
||
- 核心硬件：RK3568嵌入式开发板
|
||
- 外设模块：AI/AO采集模块、开关量模块、网络/串口模块、显示屏
|
||
|
||
#### 3.2.2 嵌入式C程序层
|
||
- 数据采集模块：20ms周期采集模拟量、开关量、AI数据
|
||
- 控制执行模块：接收参数与指令，执行配置、对时、灯光、开关控制
|
||
- 状态监测模块：自检、网口、串口状态实时上报
|
||
- 报警生成模块：异常事件生成并上传
|
||
- 通讯模块：与Python服务双向数据交互
|
||
|
||
#### 3.2.3 Python FastAPI服务层（核心）
|
||
采用**FastAPI + Uvicorn**搭建，提供**HTTP接口**和**WebSocket推送**双服务：
|
||
1. **RESTful API模块**：处理配置提交、状态查询、报警查询、控制指令
|
||
2. **WebSocket推送模块**：0.5秒推送实时数据、实时报警数据到Web端
|
||
3. **参数配置模块**：JSON文件读写、配置下发C程序
|
||
4. **实时数据模块**：定时读取C程序数据，缓存并通过WebSocket推送
|
||
5. **报警管理模块**：接收报警→存储SQLite→WebSocket推送前端
|
||
6. **设备状态模块**：采集并缓存设备运行状态
|
||
|
||
#### 3.2.4 Web界面层
|
||
- 菜单区：配置、状态、数据、报警、控制入口
|
||
- 状态区：自检、网络、串口实时状态
|
||
- 主显示区：实时数据表格、配置表单、控制按钮、报警列表
|
||
- 报警区：WebSocket实时弹窗+滚动显示
|
||
|
||
### 3.3 数据流向设计
|
||
1. **实时/报警数据流向**
|
||
嵌入式C程序 → Python → WebSocket主动推送 → Web界面（0.5秒刷新）
|
||
2. **参数配置流向**
|
||
Web界面 → HTTP POST → Python → JSON存储 + 下发C程序
|
||
3. **状态/查询流向**
|
||
Web界面 → HTTP GET → Python → 返回数据展示
|
||
|
||
## 四、接口详细设计（RESTful + WebSocket）
|
||
### 4.1 RESTful API 接口详情（完整参数+返回值）
|
||
所有接口统一返回格式：
|
||
```json
|
||
{
|
||
"code": 200, // 200=成功，400=参数错误，500=服务异常
|
||
"msg": "操作成功",
|
||
"data": {} // 业务数据
|
||
}

|

|
||
#### 2. WebSocket 地址：`ws://ip:port/ws/alarm`
|
||
**推送内容**：实时报警事件（触发即推）
|
||
```json
|
||
{
|
||
"alarm_type": "line_alarm",
|
||
"time": "2025-01-01 12:00:00",
|
||
"no": "1",
|
||
"type": "",
|
||
"content": "告警内容",
|
||
"level": "告警等级"
|
||
},
|
||
{
|
||
"alarm_type": "ai_alarm",
|
||
"time": "2025-01-01 12:00:00",
|
||
"no": "2",
|
||
"type": "",
|
||
"content": "告警内容",
|
||
"level": "告警等级"
|
||
},
|
||
{
|
||
"alarm_type": "operate_alarm",
|
||
"time": "2025-01-01 12:00:00",
|
||
"no": "3",
|
||
"type": "",
|
||
"content": "告警内容",
|
||
"level": "告警等级"
|
||
}
|
||
```
|
||
|
||
## 五、数据存储设计
|
||
### 5.1 JSON配置文件
|
||
- 路径：`/config/`
|
||
- 文件：`device.json`、`channel.json`、`setting.json`
|
||
|
||
### 5.2 SQLite报警数据库
|
||
表：`alarm_event`
|
||
| 字段 | 类型 | 说明 |
|
||
|------|------|------|
|
||
| id | INTEGER | 主键 |
|
||
| alarm_type | TEXT | 告警类型（line_alarm,ai_alarm,operate_alarm） |
|
||
| time | DATETIME | 事件发生时间 |
|
||
| no | TEXT | 线路号/通道号 |
|
||
| type | TEXT | 类型 |
|
||
| content | TEXT | 告警详情 |
|
||
| level | TEXT | 告警等级 |
|
||
|
||
## 六、安全与可靠性设计
|
||
1. **密码加密存储**，接口权限校验
|
||
2. WebSocket断线自动重连
|
||
3. 配置文件修改自动备份
|
||
4. 服务异常自动重启
|
||
|
||
## 七、总结
|
||
本方案基于**RK3568平台**，采用**FastAPI + HTTP + WebSocket**架构，满足电气量测控平台全部需求：
|
||
- RESTful API 负责配置、查询、控制
|
||
- WebSocket 负责实时数据、报警数据主动推送
|
||
- JSON 存储配置，SQLite 存储报警
|
||
- 0.5秒实时刷新，界面无卡顿、数据不丢失
|
||
|
||
系统架构轻量化、高性能，完全适配嵌入式平台运行。
