-- ============================================================
-- 重要说明：
-- 1. metric_identifier 需与产品物模型的标识符匹配
--    如果物模型标识符不同，请修改 UPDATE 语句更新对应记录
--    示例：UPDATE iot_report_threshold SET metric_identifier='X_axis_displacement' WHERE monitor_category_code='DEEP_DISPLACEMENT';
-- 2. 预警值 < 报警值 < 控制值，系统会按当前值与阈值的比较自动判断安全等级
-- 3. 如需针对特定产品配置阈值，复制以上记录并修改 product_id
-- 4. 如需针对特定设备配置阈值，复制以上记录并修改 device_id
