## 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 14:05:00 出现严重数据跳变，从 2362 mK (23.62°C) 瞬间跳升至 2550 mK (25.50°C)，随后又回落，且后续读数持续异常偏低，表明传感器可能发生故障或校准失效。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 bedroom_temp_sensor 在 14:05:00 存在极不合理的瞬时跳变。前一秒读数为 2362 (约 23.6°C)，同一秒内报告了 2550 (约 25.5°C)，这种在同一时间点或极短时间内发生超过 1.8°C 的剧烈波动不符合物理规律（除非环境温度瞬间剧变，但客厅和厨房温度均稳定在 24-25°C 左右）。",
    "推理步骤 2: 检查跳变后的数据趋势。从 14:10:00 开始，卧室温度读数迅速下降至 2470，并在 15:15:00 至 17:45:00 期间持续呈现非线性的快速下降趋势（从 2324 降至 2225），而与此同时，同屋内的其他区域（如 living_room）温度变化平缓，且厨房温度也相对稳定。这表明卧室传感器的读数不再反映真实环境，而是出现了漂移或故障。",
    "推理步骤 3: 结合独居老人场景评估风险。虽然当前未触发高温报警，但温度传感器是火灾预警系统的关键组件。如果传感器因故障无法准确上报高温（例如实际起火时读数仍显示低温），将导致烟雾报警器联动失效或人工干预延迟，对独居老人构成重大安全隐患。此外，数据中的负值或极低值（如 2176 mK = 21.76°C 虽正常，但需确认单位换算逻辑是否一致，此处主要关注 14:05 的跳变和随后的异常下降）进一步佐证了设备健康状态不佳。"

    "卧室温度曲线与客厅、厨房温度曲线走势严重背离，且在无人员进出干扰的情况下出现持续性异常降温趋势。"
  ],
  "recommended_actions": [
    "立即通知住户或物业上门检查卧室温度传感器硬件状态，尝试重启设备或更换电池。",
    "在维修前，建议通过手动方式（如手持温度计）定期监测卧室实际温度，确保老人生活环境安全。",
    "检查该传感器与其他 Matter 设备的关联配置，确认是否存在固件版本错误或通信干扰导致的误报。"

## 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: ...",

    "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: 正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "key_evidence": [
    "正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

  "threat_description": "厨房温度传感器在无人烹饪且无其他热源异常报告的情况下，出现剧烈且不符合物理规律的数值跳变（从约 24°C 瞬间升至 27°C），疑似传感器故障或数据上报错误。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 18:30 至 18:45 期间，厨房温度传感器 (kitchen_temp_sensor) 的读数从正常的 2463-2492 (x10) 突然跃升至 2711-2704 (x10)，即约 27.1°C 到 27.0°C。",
    "推理步骤 2: 结合上下文环境判断，此时入户门锁刚被手动打开不久 (18:01)，随后有人进入客厅和卧室，但日志中并未显示厨房灶具 (cook_surface) 开启、烟雾报警器触发或窗户打开等引入热源的迹象。",
    "推理步骤 3: 对比同一时间段内其他房间的温度变化，卧室温度持续下降 (从 2209 降至 2192)，符合夜间降温规律；而厨房温度的急剧上升缺乏合理的物理成因（如烤箱使用通常会有更长的预热过程或伴随其他设备动作），这种孤立且剧烈的数值突变极大概率是传感器硬件故障、校准丢失或通信干扰导致的误报。"
  ],
  "key_evidence": [
    "2026-08-14T18:30:00 厨房温度传感器读数突增至 2711 (27.11°C)，此前稳定在 24.x°C 区间。",
    "同期无厨房灶具开启记录，无烟雾报警，且住户活动主要集中在客厅和卧室，未进行高强度厨房作业。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的物理状态及电池电量，排除接触不良或损坏。",
    "建议重置该传感器并重新校准，若问题依旧则更换新设备。",
    "暂时忽略该传感器的温度告警，依赖烟雾报警器和人工巡检作为厨房安全的补充保障。"

## 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异常，日志显示为正常的家庭晨间活动及环境状态变化。",
  "reasoning": [
    "1.  occupancy传感器行为符合正常人类活动规律：主卧和主卫的占用状态在06:34至08:10之间出现波动（如主卫短暂占用后离开），随后在早晨时段保持活跃，符合住户起床、洗漱、准备出门的日常作息。",
    "2.  温度数据趋势合理：客厅温度从凌晨的约23°C缓慢上升至上午的25°C左右，这是典型的室内环境温度随日照或空调关闭后的自然升温过程，无剧烈跳变或传感器故障迹象。",
    "3.  门锁与门窗状态逻辑一致：07:14左右入户门关闭并上锁（LockState=1），同时玄关/入口区域有人员活动记录，符合住户离家或归家的正常场景，未发现非法入侵或尾随迹象。",
    "4.  关键设备状态无冲突：厨房灶具在07:14关闭，之后无长时间无人看管烹饪的迹象；烟雾报警器和漏水传感器无触发记录。"

    "异常活动检测：在 07:29:30 至 10:59:00 期间，尽管入户门处于锁定状态，但 living_room_occupancy 和 kids_room_occupancy 多次报告为 1（有人）。特别是 08:40:00 左右，儿童房再次被检测到有人，而此时主卧和次卧均无人，不符合家庭内部成员起床活动的常规逻辑。",
    "环境数据佐证：从 01:00 开始，living_room_temp_sensor 读数从 23.08°C 持续线性上升至 11:30 的 25.36°C，随后缓慢下降。这种持续升温趋势与空调开启或人员聚集产热有关，结合夜间无人时的低温起点，强烈暗示有外部热源进入或设备长时间运行，进一步支持入侵假设而非传感器故障。"

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。

{
  "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: 正常样本空调开启后温度逐步下降；异常样本持续不降反升。"
  ],
  "key_evidence": [
    "正常样本空调开启后温度逐步下降；异常样本持续不降反升。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "客厅温度传感器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: 在 2026-07-03T13:00:00，系统检测到客厅空调 (living_room_ac) 被开启 (OnOff.OnOff = True)，此时客厅温度约为 25.0°C (2502 mK)，符合正常物理规律。",
    "推理步骤 2: 随后在 13:15:00，温度读数突然飙升至 28.4°C (2840 mK)，虽然略高但尚在合理波动范围内；然而紧接着在 13:35:00，读数再次异常跳变至 27.2°C (2720 mK)。",
    "推理步骤 3: 最关键的异常发生在 13:55:00，当其他房间（厨房、次卧、主卧）的温度均稳定下降或处于正常范围时，客厅温度读数瞬间回弹至 26.1°C (2610 mK)，随后在 14:00:00 又骤降至 24.67°C。这种在短时间内（几分钟内）反复剧烈震荡且与空调制冷趋势完全背离的读数，极大概率是传感器硬件故障、通信丢包导致的随机值，或是固件逻辑错误，而非真实的室温变化。"
  ],
  "key_evidence": [
    "2026-07-03T13:00:00 空调开启，初始温度正常 (2502 mK)。",
    "2026-07-03T13:55:00 温度读数出现无规律的剧烈跳变 (2610 mK)，与其他房间降温趋势不符。",
    "数据序列中缺乏平滑过渡，呈现典型的 'Sensor Stuck' 或 'Drift' 特征。"
  ],
  "recommended_actions": [
    "立即检查客厅温度传感器的物理连接及供电状态。",
    "尝试重启客厅温度传感器设备以重置其内部状态。",

    "2. 重点设备（客厅窗户）状态分析：任务指定的重点设备 living_room_window 在 09:10 被打开（CurrentPositionLiftPercent100ths = 5000，即50%开启），同时 contact_sensor 状态由 True 变为 False（表示窗户打开）。约10分钟后（09:20），contact_sensor 恢复为 True（表示窗户关闭）。这一“开窗-关窗”的完整闭环操作发生在白天且有人居住期间，属于正常的通风换气行为，非入侵迹象。",
    "3. 传感器数据合理性检查：温度传感器读数（如 2373, 2421 等）呈现随时间缓慢上升的趋势（从凌晨23.7°C升至上午25.5°C左右），这符合夏季清晨室温随日照和人体活动逐渐升高的物理规律，无突变或停滞，表明传感器工作正常，无 drift 或 malfunction。",
    "4. 门锁与安防逻辑：入户门在 08:34 有一次手动开锁记录，随后玄关和客厅均有人员活动，推测为老人外出买菜或散步后返回，或者仅仅是室内移动导致的误报（若为智能锁内部逻辑），但结合后续长时间的人员活跃状态，整体场景连贯，未发现非法入侵特征。"

    "推理步骤 2: 从 10:54:30 到日志结束 (12:06:00)，厨房运动传感器持续报告有人 (Occupancy=1)，但随后在 11:30:00 至 11:59:00 期间，厨房温度读数出现剧烈波动并维持在极高水平 (约 253°C - 255°C，即 Matter 协议中的 253K-255K 约为 -20°C 至 -18°C？不，Matter 温度单位通常是十进制摄氏度或华氏度，需校准。若为摄氏度，250+ 度不可能；若为毫开尔文或特定缩放值，2373 对应约 21°C (2373/100 + 273.15? 不对。通常 Matter 温度是十进制摄氏度。让我们重新检查数值逻辑：2373 -> 23.73°C? 可能是乘以 0.01。2373 * 0.01 = 23.73°C。2557 * 0.01 = 25.57°C。这符合室温升温逻辑。)",
    "修正推理步骤 2: 数据校准：日志中的温度值（如 2373）应理解为 23.73°C（Matter 常见编码方式）。厨房温度从正常的 ~24°C 迅速攀升至 25.5°C 以上，并在 10:54 开启灶具后持续处于高位，表明热源正在工作。",
    "推理步骤 3: 关键风险点在于，虽然厨房有人，但老人独居，且从 10:54 开启灶具到 12:06 日志结束，长达 1 小时以上的高温持续状态。对于独居老人而言，长时间无人看管或注意力分散导致的烹饪过热是主要隐患。尽管有 occupancy 信号，但无法确认是否有人实际在操作或监控火候，高温持续上升的趋势（从 24°C 升至 25.5°C+）结合灶具开启事件，构成了明确的火灾前兆风险。",
    "推理步骤 4: 对比其他房间，卧室和客厅温度正常，唯独厨房温度显著偏高且与灶具开启时间高度相关，排除了传感器漂移的可能性，确认为真实的热源异常。"
