设备巡检管理系统实施全流程：需求确认→开发测试→上线推广的6个关键步骤详解

// 设备巡检任务调度核心代码示例
public class InspectionScheduler
{
    private readonly IInspectionRepository _repository;
    
    public InspectionScheduler(IInspectionRepository repository)
    {
        _repository = repository;
    }
    
    // 生成每日巡检计划
    public List GenerateDailyPlan(DateTime date)
    {
        var equipmentList = _repository.GetAllEquipment();
        var tasks = new List();
        
        foreach (var equipment in equipmentList)
        {
            if (equipment.RequiresDailyInspection)
            {
                tasks.Add(new InspectionTask
                {
                    EquipmentId = equipment.Id,
                    ScheduledTime = date.AddHours(9), // 默认上午9点
                    InspectorId = equipment.AssignedInspectorId,
                    Status = InspectionStatus.Pending
                });
            }
        }
        
        return tasks;
    }
}

// 前端巡检数据提交示例
class InspectionDataService {
  // 提交巡检数据
  async submitInspectionData(inspectionData) {
    try {
      // 检查网络连接
      if (!navigator.onLine) {
        // 保存到本地存储，待网络恢复后同步
        await this.saveToLocalStorage(inspectionData);
        return { success: true, offline: true };
      }
      
      // 在线提交数据
      const response = await fetch('/api/inspections/submit', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify(inspectionData)
      });
      
      return await response.json();
    } catch (error) {
      console.error('提交巡检数据失败:', error);
      throw new Error('数据提交失败，请稍后重试');
    }
  }
  
  // 保存到本地存储
  async saveToLocalStorage(data) {
    const pendingData = await this.getPendingData();
    pendingData.push({
      data,
      timestamp: new Date().toISOString()
    });
    localStorage.setItem('pendingInspections', JSON.stringify(pendingData));
  }
}

-- 巡检数据查询优化示例
-- 创建索引提高查询性能
CREATE INDEX IX_Inspections_EquipmentId_Date 
ON Inspections (EquipmentId, InspectionDate);

-- 优化后的巡检报表查询
SELECT 
    e.EquipmentName,
    e.EquipmentType,
    COUNT(i.Id) AS TotalInspections,
    SUM(CASE WHEN i.Status = 'Normal' THEN 1 ELSE 0 END) AS NormalCount,
    SUM(CASE WHEN i.Status = 'Abnormal' THEN 1 ELSE 0 END) AS AbnormalCount
FROM Equipment e
LEFT JOIN Inspections i ON e.Id = i.EquipmentId
WHERE i.InspectionDate BETWEEN @StartDate AND @EndDate
GROUP BY e.EquipmentName, e.EquipmentType
ORDER BY TotalInspections DESC;
