## 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",

    "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_description": "未检测到安全威胁或设备故障，日志显示为独居老人在夏季早晨正常的起床、活动及开窗通风行为。",
  "reasoning": [
    "1. **时间与环境背景分析**：日志时间为2026年7月2日（夏季），室内温度从凌晨的约23.7°C逐渐上升至上午的25.5°C左右，符合夏季清晨气温自然升高的规律。",
    "2. **用户行为模式匹配**：06:51 入户门解锁并打开，随后玄关和厨房传感器陆续检测到人员活动（Occupancy=1），表明老人已起床并开始日常活动。08:37 门锁手动上锁，符合离家或短暂外出后返回/再次锁门的习惯。",
    "3. **重点设备状态解析**：09:10 客厅窗帘开启至50%位置，同时窗户接触传感器由False变为True（表示窗户被推开）。在室温持续升高（25.5°C）的背景下，开窗通风是合理的降温行为，并非异常入侵或设备误报。",
    "4. **排除异常风险**：虽然厨房温度传感器在10:51出现一次 `None` 值，但随后立即恢复正常读数，且无烟雾报警或漏水警报，推测为瞬时通信丢包而非设备故障。整体活动轨迹连贯，无长时间静止（跌倒风险低）或夜间异常活动。"

    "推理步骤 2: 结合住户画像（独居老人）和场景，厨房在早晨时段出现长时间的高温状态，且期间有多次人员进出记录（entrance_occupancy, kitchen_occupancy），这不符合正常休息时的环境特征，强烈暗示正在进行烹饪或其他产热活动。",
    "推理步骤 3: 虽然日志中未直接触发烟雾报警，但温度持续处于高位区间（特别是相比卧室和客厅的温差趋势）是火灾发生前的典型前兆。对于独居老人家庭，这种无明确降温动作且持续高温的状态属于高危安全事件。"

## 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",
  "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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本是起床链路的短时活动；异常样本是长时间单点持续 Occupied。"
  ],
  "key_evidence": [
    "正常样本是起床链路的短时活动；异常样本是长时间单点持续 Occupied。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器出现数据丢失（None）且数值异常波动，同时全屋温度读数严重偏离正常物理范围，表明传感器存在硬件故障或校准失效。",
  "reasoning": [
    "推理步骤 1: 日志显示在 2026-07-02T06:44:10 时，kitchen_temp_sensor 报告了 'MeasuredValue = None'，这通常表示传感器通信中断、供电不稳或内部 ADC 读取失败，属于典型的 sensor_malfunction 迹象。",
    "推理步骤 2: 即使排除数据丢失，该传感器的读数也完全不符合物理规律。从凌晨到上午，厨房温度从约 23°C (2396 mK) 线性上升至超过 25.5°C (2550 mK)，且在无人操作的情况下持续攀升，这种非自然的快速升温曲线极可能是传感器漂移或损坏导致的误报。",
    "推理步骤 3: 结合其他房间的温度传感器数据（如 living_room 和 master_bedroom），虽然它们也有上升趋势，但厨房作为热源集中区，其温度变化幅度过大且伴随数据丢包，进一步证实了该特定设备存在健康隐患，而非单纯的环境过热。"
  ],
  "key_evidence": [
    "2026-07-02T06:44:10 kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None",
    "kitchen_temp_sensor 读数在数小时内从 ~23.96°C 异常飙升至 ~25.50°C，且伴随数据缺失事件。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的电池电量及连接状态，尝试重启设备。",
    "若重启无效，建议更换厨房温度传感器，以防因误报高温触发不必要的火灾警报或掩盖真实火情。",
    "暂时手动监控厨房环境温度，确保无实际火灾隐患。"
  ]
}

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。

    "2. 照明与电器控制逻辑：20:10卧室灯开启并调光，随后在20:50关闭，20:33卫生间灯开启，这些操作时间点和持续时间（如洗澡、睡前准备）符合老年人的生活习惯，无异常长亮或频繁误触现象。",
    "3. 环境数据稳定性：各房间温度传感器读数随时间缓慢变化（如客厅从23.6°C降至22.4°C左右），符合夏季傍晚气温自然下降的趋势，未发现传感器漂移或故障导致的跳变。",
    "4. 安全设备状态：日志中未出现烟雾报警器、一氧化碳报警器或漏水传感器的报警事件，门锁操作均为Manual（手动），无暴力破解或异常远程访问迹象。"

    "2026-07-03T20:10:00 bedroom_light | OnOff.OnOff = True 及后续调光 - 正常的睡前照明行为。",
    "TemperatureMeasurement.MeasuredValue 数值呈平滑下降趋势 - 排除传感器硬件故障。"
  ],
  "recommended_actions": [

## 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",

    "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": "当前日志更符合正常模式，不建议报警。",

  "threat_description": "客厅温度传感器 (living_room_temp_sensor) 在空调开启后出现严重的数据跳变和逻辑矛盾，显示设备可能故障或受到干扰。",
  "reasoning": [
    "推理步骤 1: 数据单位分析。日志中的温度值（如 2261, 2508）明显超出了常规摄氏度范围，结合 Matter 协议常见实现，这些数值极有可能是以 0.01°C 为单位的原始整数读数（即实际温度为 22.61°C - 25.08°C），符合夏季室内正常室温范围。",
    "推理步骤 2: 异常跳变检测。在 2026-08-26T13:15:00，当客厅空调 (living_room_ac) 刚刚开启时，温度读数从正常的 28.40°C (2840) 瞬间跳变为 27.20°C (2720)，随后在 13:55:00 再次出现剧烈波动，从 24.81°C 瞬间变为 26.10°C。这种非物理性的瞬时大幅跳变不符合热力学规律。",
    "推理步骤 3: 逻辑一致性验证。尽管存在上述跳变，但整体趋势显示：随着空调开启 (13:00, 17:57)，后续读取的温度值（如 14:00 的 24.70°C, 18:40 的 23.11°C）呈现持续下降趋势，且与其他房间（主卧、厨房）的温度变化趋势基本一致（均随时间推移逐渐降低）。这表明传感器并未完全失效（如卡死在固定值），而是存在间歇性的数据漂移或通信噪声导致的读数错误。",
    "推理步骤 4: 结论判定。虽然整体温控逻辑有效，但传感器输出的高频、大幅度无规律跳变属于典型的传感器故障（Sensor Malfunction）或校准漂移，可能导致用户端显示温度不准，影响舒适度控制策略。"
  ],
  "key_evidence": [
    "2026-08-26T13:15:00 至 13:35:00 期间，温度读数在 2720 (27.2°C) 和 2840 (28.4°C) 之间剧烈震荡，而周围其他房间温度稳定下降。",
    "2026-08-26T13:55:00 出现单次采样内从 24.81°C 突变至 26.10°C 的现象，随后立即回落至 24.81°C，表现出明显的信号不稳定特征。"
  ],
  "recommended_actions": [
    "建议检查客厅温度传感器的电池电量及安装位置是否受阳光直射或热源干扰。",
    "建议在智能家居系统中对该传感器进行重新校准或重置，若问题持续则考虑更换硬件。",
    "暂时依赖其他房间的温度传感器作为客厅温度的参考依据，直到故障排除。"

    "数据单位分析：日志中的温度值（如 2374, 2558）远超人类居住环境的合理范围（通常 18-30°C）。结合 Matter 协议常见实现，这极有可能是摄氏度乘以 10 后的整数表示（即实际温度为 23.74°C - 25.58°C），或者是传感器固件将原始 ADC 值直接上报而未进行正确的线性转换。",
    "趋势合理性验证：尽管数值巨大，但观察 `living_room_temp_sensor` 从凌晨 03:10 的 2374 逐渐上升至上午 09:10 的 2558，随后在中午开始缓慢下降的趋势，与一天中室内温度随日照和空调运行变化的自然规律高度吻合。如果是真实的火灾或设备过热，温度应在短时间内急剧飙升并伴随烟雾报警触发，而非呈现这种平缓的日变化曲线。",
    "关联设备状态佐证：在同一时间段内，`living_room_occupancy` 多次报告为 0（无人），且 `front_door_contact` 和 `front_door_lock` 状态正常（门锁已锁，门未开），排除了有人闯入导致的高温热源可能性。同时，厨房温度传感器也出现了类似的“高位”读数（如 2547），进一步证实这是全屋温度传感器的系统性标定问题或数据格式误解，而非单一房间的真实火情。"

  "key_evidence": [
    "living_room_temp_sensor 读数在 2374 至 2558 之间波动，远超安全阈值，但变化曲线平滑符合昼夜温差规律。",
    "同一时期 kitchen_temp_sensor 也出现类似的高位读数（2492-2557），表明是全局性的传感器数据解析或校准问题，而非局部真实高温。",
    "occupancy_sensor 持续报告无人在场，且门窗传感器状态正常，排除了人为制造高温源的可能性。"
  ],
  "recommended_actions": [
    "立即检查客厅和厨房温度传感器的硬件连接及供电情况，排除接触不良导致的信号错误。",
    "登录智能家居平台查看该传感器的配置参数，确认是否开启了错误的缩放因子（Scale Factor）或单位设置（例如误将 mK 当作 °C 处理，或者代码中将值放大了 10 倍）。",
    "如果无法通过软件修复，建议更换温度传感器，因为持续的读数错误可能导致空调系统误判（如过度制冷或制热），造成能源浪费或设备损坏。"
