## 任务
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",

  "threat_description": "卧室温度传感器 (bedroom_temp_sensor) 在 14:00 出现严重数据跳变，且后续读数与客厅环境及人体热力学规律严重不符，疑似设备故障或校准失效。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-07-16T13:55:45 时，卧室运动传感器报告无人 (Occupancy=0)，随后卧室温度从正常的约 24°C (2393 mK) 开始缓慢下降，符合夜间/清晨无人的自然冷却趋势。",
    "推理步骤 2: 关键异常发生在 2026-07-16T14:00:00，同一秒内该传感器连续上报了两个截然不同的值：2289 mK (约 1.7°C) 和 2550 mK (约 22.3°C)。这种在同一毫秒级时间窗口内的剧烈跳变（温差超过 20°C）在物理上是不可能的，除非传感器瞬间被极端热源/冷源冲击，但这与环境状态（无人、窗户关闭）矛盾。",
    "推理步骤 3: 随后的数据进一步证实了故障。从 14:05 到 15:30，虽然运动传感器持续报告无人，但温度读数在 22°C 至 25°C 之间剧烈震荡（例如 14:05 为 2550mK，14:10 骤降至 2470mK，14:30 又降至 2361mK）。如果房间真的有人活动，温度应相对稳定或随人体散热微升；如果无人，温度应平稳下降。这种‘无人却高温震荡’的模式表明传感器内部电路不稳定或校准丢失，导致测量值随机漂移。",
    "推理步骤 4: 对比客厅温度传感器 (living_room_temp_sensor)，其读数在同期稳定在 24°C-25°C 之间，且逻辑连贯，证明环境温度正常，排除了外部极端天气导致全屋温度异常的可能性，确认为单点设备故障。"

    "14:00 - 15:30 期间，在无人员活动的情况下，温度读数呈现非物理规律的剧烈震荡而非平稳变化。",
    "同期客厅温度传感器数据稳定且符合常理，形成鲜明对比。"
  ],
  "recommended_actions": [
    "立即将 bedroom_temp_sensor 标记为离线或不可信，并在智能家居系统中暂时禁用其报警功能以防误报。",
    "安排技术人员上门检查或更换卧室温度传感器硬件。",
    "在维修前，建议用户手动使用独立温度计监测卧室实际温度，以确保空调控制逻辑（若联动）能基于正确数据运行。"

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "设备状态正常，日志显示为独居老人在早晨起床后的常规活动及环境数据上报，无安全威胁。",
  "reasoning": [
    "1. **时间与环境背景分析**：日志时间为2026年8月5日清晨至中午（03:10-12:08）。此时段气温传感器读数在23°C-25°C之间（Matter协议中温度值通常以厘度为单位，即2367=23.67°C），属于舒适的室内环境温度，未触发高温或低温警报。",
    "2. **人员活动模式符合预期**：06:38卧室有人，随后06:42厨房有人，08:31客厅有人，09:10窗帘打开。这符合独居老人早晨起床、洗漱、准备早餐/用餐、并在上午开启窗帘透光的正常生活规律。",
    "3. **重点设备行为逻辑自洽**：任务关注的`living_room_window`和`living_room_window_contact`在09:10同时记录到窗帘位置变化（CurrentPositionLiftPercent100ths = 5000，即50%开启）和接触传感器状态变为False（关闭/遮挡）。这表明是住户主动操作窗帘，且动作连贯，非异常震动或故障导致的误报。",
    "4. **门锁与安防状态正常**：06:57入户门传感器显示False（关闭），门锁LockState为1（锁定）。结合后续长时间无外人进入迹象（仅内部房间移动），且老人一直在家活动，排除入侵风险。",
    "5. **无危险源迹象**：厨房灶具虽有人活动，但未检测到烟雾报警器报警或漏水传感器触发，且温度上升平缓，符合烹饪或日常活动特征，无未看管烹饪或火灾风险。"
  ],
  "key_evidence": [
    "09:10:00 living_room_window CurrentPositionLiftPercent100ths = 5000 与 living_room_window_contact StateValue = False 同步发生，确认为正常的窗帘开合操作。",
    "06:38 - 12:08 期间，卧室、厨房、客厅、玄关等多个区域Occupancy传感器持续交替显示为1，证明住户处于清醒和活动状态，排除了跌倒或异常静止（abnormal_inactivity）的风险。",
    "所有温度传感器读数在23-25摄氏度范围内，无极端值。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控晨间活动规律，若未来出现长时间无活动记录或门窗在非习惯时间开启，再行介入。"
  ]
}
```

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在活跃烹饪时段出现数据丢失（None），且随后数值异常波动，表明设备故障或通信中断。",
  "reasoning": [
    "推理步骤 1: 日志显示从 06:42 开始，厨房运动传感器频繁检测到有人（Occupancy = 1），且厨房温度持续上升（从 2489 升至 2557），符合独居老人起床后准备早餐的正常行为模式。",
    "推理步骤 2: 在 11:11:00 这一关键时间点，厨房温度传感器报告值为 None，紧接着在 11:40:00 和 12:05:00 恢复报告数值时，读数出现了非线性的剧烈跳变（如从正常的 2537 突然降至 2519，而周围卧室温度稳定在 2440-2450 之间）。",
    "推理步骤 3: 考虑到住户为独居老人，厨房是火灾高风险区域，传感器数据的突然丢失和随后的不稳定读数极有可能是硬件故障、电池耗尽或 Matter 协议通信中断导致的，而非真实的环境温度变化。这种故障可能导致无法及时触发烟雾报警或空调联动，构成安全隐患。"

  "key_evidence": [
    "2026-08-05T11:11:00 kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None (在有人且高温环境下)",
    "2026-08-05T11:40:00 kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2531 (相比前一刻的 2557 出现无逻辑下降，而卧室温度未发生同等幅度变化)"

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

    "推理步骤 2: 结合上下文，同一时间段内 bedroom_temp_sensor 和 kitchen_temp_sensor 报告的数值均在 2000-2200 左右的合理范围（代表约 20-22°C）。根据 Matter 协议标准及常规传感器逻辑，温度值通常以 0.1°C 为单位，因此 2342 实际代表 23.42°C，但考虑到卧室和厨房的读数明显偏低且符合夏季室内常态，而客厅读数异常偏高且无空调开启记录（日志中未见 air_conditioner 状态变化），该数值极大概率是传感器硬件故障、校准错误或数据包损坏导致的漂移。",
    "推理步骤 3: 对于独居老人家庭，准确的温度监测至关重要，用于预防过热风险或判断老人是否处于异常环境。一个持续报错的传感器会导致系统误判环境温度，掩盖真实的安全隐患（如火灾前兆的高温或极端低温），属于关键安全设备失效。"

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "reasoning": [
    "推理步骤 1: 正常模式下，厨房温度应在室温至烹饪加热范围内波动（约 20-50°C，即 293K-323K）。日志中厨房温度传感器读数从正常的 ~2400 (21.7°C) 开始，在 19:15 突然飙升至 2551 (228°C)，并在 19:20-19:40 期间持续维持在 2600-2688 (232°C-241°C) 的极端高温区间，这远超物理常识（除非发生剧烈爆炸或火灾，但无其他火警信号支持）。",
    "推理步骤 2: 关键时间点是 19:49:08，洗碗机状态变为运行中 (OperationalState = 1)。虽然洗碗机会产生热量，但绝不可能将环境温度瞬间提升至 230°C+。这种温度跃升与设备动作的时间关联性暗示传感器读数错误，而非真实环境变化。",
    "推理步骤 3: 在 19:32:00 曾短暂出现 `MeasuredValue = None`，随后又恢复为异常高值，这种数据中断和恢复的模式是典型的传感器硬件故障、通信丢包或固件崩溃的表现，进一步证实了 `sensor_malfunction` 而非真实的火灾风险（因为烟雾报警器未触发且温度回落趋势不符合火灾特征）。"

    "2026-07-28T19:32:00 传感器数据短暂丢失 (None)，随后再次报告异常高温，且此时洗碗机尚未启动。",
