+# Farms静态数据导入总结
+
+## 概述
+成功将后端API中的farms静态数据导入到数据库的farms表中。
+
+## 数据来源
+
+### 1. API静态数据
+来源：`routes/farms.js` 中的 `/public` 路由
+- 宁夏农场1 (银川市)
+- 宁夏农场2 (石嘴山市) 
+- 宁夏农场3 (吴忠市)
+
+### 2. 种子数据
+来源：`seeds/20230102000000_farm_data.js` 和 `seeds/20230103000000_extended_data.js`
+- 阳光农场 (养猪场)
+- 绿野牧场 (养牛场)
+- 山谷羊场 (养羊场)
+- 蓝天养鸡场 (养鸡场)
+- 金山养鸭场 (养鸭场)
+- 银河渔场 (渔场)
+- 星空牧场 (综合养殖场)
+- 彩虹农庄 (有机农场)
+
+## 导入过程
+
+### 1. 创建导入脚本
+文件：`import-farms-static-data.js`
+- 合并API静态数据和种子数据
+- 使用事务确保数据一致性
+- 清空现有数据并重置自增ID
+- 批量插入新数据
+
+### 2. 执行导入
+```bash
+node import-farms-static-data.js
+```
+
+### 3. 验证导入结果
+文件：`verify-farms-import.js`
+- 数据完整性检查
+- ID序列连续性验证
+- 地理位置数据验证
+- 农场类型统计
+
+## 导入结果
+
+### 数据统计
+- **总计**：11个农场
+- **ID范围**：1-11（连续）
+- **数据完整性**：✅ 所有字段完整
+- **地理位置**：✅ 所有位置数据有效
+
+### 农场类型分布
+| 类型 | 数量 |
+|------|------|
+| 综合农场 | 3个 |
+| 养猪场 | 1个 |
+| 养牛场 | 1个 |
+| 养羊场 | 1个 |
+| 养鸡场 | 1个 |
+| 养鸭场 | 1个 |
+| 渔场 | 1个 |
+| 综合养殖场 | 1个 |
+| 有机农场 | 1个 |
+
+### API验证
+- `/api/farms/public` ✅ 返回正确的静态数据
+- `/api/farms` ✅ 返回完整的数据库数据
+
+## 数据结构
+
+每个农场记录包含以下字段：
+- `id`: 主键，自增
+- `name`: 农场名称
+- `type`: 农场类型
+- `location`: 地理位置（JSON格式，包含lat和lng）
+- `address`: 详细地址
+- `contact`: 联系人
+- `phone`: 联系电话
+- `status`: 状态（active/inactive/maintenance）
+- `created_at`: 创建时间
+- `updated_at`: 更新时间
+
+## 相关文件
+
+### 创建的文件
+- `import-farms-static-data.js` - 数据导入脚本
+- `verify-farms-import.js` - 数据验证脚本
+- `farms-data-import-summary.md` - 本总结文档
+
+### 涉及的现有文件
+- `routes/farms.js` - API路由定义
+- `models/Farm.js` - 数据模型定义
+- `controllers/farmController.js` - 控制器逻辑
+- `seeds/20230102000000_farm_data.js` - 种子数据
+- `seeds/20230103000000_extended_data.js` - 扩展种子数据
+
+## 注意事项
+
+1. **数据库连接警告**：执行过程中出现循环依赖警告，但不影响功能
+2. **事务安全**：使用数据库事务确保数据导入的原子性
+3. **ID重置**：导入前重置了自增ID，确保从1开始
+4. **数据覆盖**：导入过程会清空现有farms数据
+
+## 后续建议
+
+1. 定期备份farms数据
+2. 考虑添加数据迁移脚本
+3. 优化循环依赖问题
+4. 添加更多数据验证规则
+
+---
+
+**导入完成时间**：2025-08-21  
+**状态**：✅ 成功完成

+
+#### 2.3.1 Python环境配置与依赖管理
+1. `uv` 是一个快速的 Python 包和虚拟环境管理工具
+2. MCP Server 依赖 `uv` 工具运行，必须确保系统环境中已安装 uv
+3. 安装 `uv` 的推荐方法：
+   - 使用官方安装脚本：`powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"`
+   - 或通过 pip 安装：`pip install uv`
+4. 设置国内镜像源加速下载：
+   ```bash
+   $env:UV_INDEX_URL="https://mirrors.aliyun.com/pypi/simple/"
+   ```
+
+### 2.4 部署架构
+- **开发环境**: 本地运行
+- **生产环境**: Docker容器化部署
+
+## 3. 数据库设计
+
+### 3.1 数据库连接信息
+- 数据库地址：http://192.168.0.240:3306
+- 数据库用户名：root
+- 数据库密码：aiot$Aiot123
+- 数据库名称：nxxmdata
+
+### 3.2 数据库连接失败解决方案
+在开发过程中，可能会遇到数据库连接失败的问题，此时应采取以下措施：
+
+1. **确认MySQL服务状态**:
+   - 确保MySQL服务已经安装并正在运行
+   - 检查MySQL是否在默认端口3306上运行和监听
+
+2. **创建数据库**:
+   - 可以执行项目中的SQL文件来创建数据库和表
+   - 根据项目中的 schema.sql 文件，手动执行创建数据库和表的SQL语句
+
+3. **提供正确的连接参数**:
+   - 需要提供正确的数据库连接信息，包括主机地址（host）、端口号（port）、用户名（user）、密码（password）、数据库名（database）
+   - 验证主机地址、端口号、用户名、密码等连接参数的正确性
+   - 确保提供完整的数据库配置参数，检查参数格式是否符合MCP工具的要求
+
+4. **连接验证参数**:
+   - 主机: `localhost` 或 `127.0.0.1`
+   - 端口: `3306` (MySQL默认端口)
+   - 用户名: MySQL用户名 (例如: `root`)
+   - 密码: MySQL密码
+   - 数据库: `nxxmdata`
+
+5. **处理未知数据库问题**:
+   - 如果遇到"Unknown database"错误，应手动创建相应的数据库
+   - 使用schema.sql文件创建数据库结构
+   - 确保在连接数据库前完成数据库的初始化工作
+
+6. **验证数据库连接**:
+   - 在完成数据库创建和配置后，再次尝试连接数据库
+   - 通过执行简单的数据库操作验证连接的有效性
+
+当无法直接连接数据库时，可以通过创建完整的数据库设计文档和SQL脚本文件来提供替代方案。这种方法可以确保设计工作继续进行，并为后续的数据库部署提供可执行的起点。

+### 事件系统
+
+性能监控系统提供了一个事件系统，可以监听各种性能相关的事件：
+
+```javascript
+const { perfEvents } = require('./backend/utils/performance-monitor');
+
+// 监控启动事件
+perfEvents.on('monitoringStarted', (data) => {
+  console.log(`性能监控已启动，间隔: ${data.interval}ms`);
+});
+
+// 监控停止事件
+perfEvents.on('monitoringStopped', () => {
+  console.log('性能监控已停止');
+});
+
+// 数据库状态变化事件
+perfEvents.on('databaseStatus', (status) => {
+  console.log('数据库状态更新:', status);
+});
+
+// 数据库错误事件
+perfEvents.on('databaseError', (error) => {
+  console.error('数据库错误:', error);
+});
+
+// 慢查询事件
+perfEvents.on('slowQuery', (query) => {
+  console.warn(`检测到慢查询: ${query.duration}ms - ${query.query}`);
+});
+
+// API错误事件
+perfEvents.on('apiError', (data) => {
+  console.error(`API错误: ${data.method} ${data.path} - ${data.error}`);
+});
+
+// 慢API请求事件
+perfEvents.on('slowApiRequest', (data) => {
+  console.warn(`慢API请求: ${data.endpoint} - ${data.duration}ms`);
+});
+
+// 高CPU使用率事件
+perfEvents.on('highCpuUsage', (data) => {
+  console.warn(`高CPU使用率: ${data.usage}% (阈值: ${data.threshold}%)`);
+});
+
+// 高内存使用率事件
+perfEvents.on('highMemoryUsage', (data) => {
+  console.warn(`高内存使用率: ${data.usage}% (阈值: ${data.threshold}%)`);
+});
+
+// 高磁盘使用率事件
+perfEvents.on('highDiskUsage', (data) => {
+  console.warn(`高磁盘使用率: ${data.usage}% (阈值: ${data.threshold}%)`);
+});
+```
+
+## 前端组件
+
+`PerformanceMonitor.vue` 组件提供了一个直观的界面，用于展示性能指标和配置警报阈值。它包括以下功能：
+
+- 系统资源监控面板（CPU、内存、磁盘）
+- 数据库性能监控面板（连接池、慢查询、查询模式）
+- API性能监控面板（请求统计、响应时间、错误率）
+- 警报配置面板（设置各项指标的警报阈值）
+- 实时图表展示历史趋势
+
+## 最佳实践
+
+### 性能监控
+
+1. **设置合适的监控间隔**：根据应用负载和服务器资源选择合适的监控间隔。高负载系统可能需要更长的间隔（如5分钟），而关键系统可能需要更短的间隔（如30秒）。
+
+2. **配置合理的警报阈值**：根据系统特性和业务需求设置合理的警报阈值。过低的阈值可能导致过多的警报，过高的阈值可能导致问题被忽略。
+
+3. **定期分析性能数据**：定期查看性能监控数据，识别潜在问题和优化机会。
+
+### 数据库优化
+
+1. **关注慢查询**：定期检查慢查询列表，优化频繁出现的慢查询。
+
+2. **监控连接池**：保持合理的连接池大小，避免连接池耗尽或过度分配。
+
+3. **分析查询模式**：利用查询模式统计，识别频繁执行的查询，考虑添加索引或优化查询结构。
+
+### API优化
+
+1. **关注慢响应API**：优化响应时间超过阈值的API端点。
+
+2. **监控错误率**：保持低错误率，及时修复错误率高的API端点。
+
+3. **平衡请求负载**：避免单个端点过度负载，考虑负载均衡或缓存策略。
+
+## 故障排除
+
+### 常见问题
+
+1. **监控系统占用过多资源**：
+   - 增加监控间隔
+   - 减少收集的指标
+   - 限制历史数据存储量
+
+2. **警报过多**：
+   - 调整警报阈值
+   - 合并相似警报
+   - 实现警报抑制机制
+
+3. **数据不准确**：
+   - 检查监控代码是否正确集成
+   - 验证数据源是否可靠
+   - 确保时间同步
+
+### 日志文件
+
+性能监控系统会在 `logs/performance` 目录下生成以下日志文件：
+
+- `system-YYYY-MM-DD.log`：系统资源监控日志
+- `database-YYYY-MM-DD.log`：数据库性能监控日志
+- `system-error-YYYY-MM-DD.log`：系统监控错误日志
+- `database-error-YYYY-MM-DD.log`：数据库监控错误日志
+
+## 扩展和定制
+
+### 添加新的监控指标
+
+要添加新的监控指标，需要修改以下文件：
+
+1. `performance-monitor.js`：添加新的指标收集和处理逻辑
+2. `performance-routes.js`：添加新的API端点
+3. `PerformanceMonitor.vue`：添加新的UI组件展示指标
+
+### 集成外部监控系统
+
+性能监控系统可以与外部监控系统集成，如Prometheus、Grafana或ELK堆栈：
+
+```javascript
+// 示例：将性能指标导出到Prometheus
+const client = require('prom-client');
+const register = new client.Registry();
+
+// 创建指标
+const cpuGauge = new client.Gauge({
+  name: 'cpu_usage_percent',
+  help: 'CPU使用率百分比',
+  registers: [register]
+});
+
+// 更新指标
+perfEvents.on('systemMetrics', (metrics) => {
+  cpuGauge.set(metrics.cpuUsage.usage);
+});
+
+// 暴露指标端点
+app.get('/metrics', (req, res) => {
+  res.set('Content-Type', register.contentType);
+  res.end(register.metrics());
+});
+```
+
+## 结论
+
+性能监控系统提供了全面的工具，用于监控和优化应用程序的性能。通过实时跟踪系统资源、数据库性能和API响应时间，可以及早发现潜在问题，提高应用程序的可靠性和用户体验。
+
+定期查看性能指标，设置合理的警报阈值，并根据性能数据进行优化，可以显著提高应用程序的性能和稳定性。
