## 任务
请从下面的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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": [

    "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": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到厨房区域在无人状态下出现持续高温且伴随灶具异常激活迹象，存在极高的火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，从 02:10 开始厨房运动传感器检测到有人 (Occupancy=1)，但随后在 02:30、03:00、03:30、04:00 等多次报告中厨房 occupancy 变为 0，表明住户已离开厨房或全屋无人。",
    "推理步骤 2: 尽管人员离开，厨房温度传感器读数却呈现持续上升趋势（从 02:10 的 232.1°C 升至 04:20 的 241.2°C），远超正常室温范围（约 22-25°C，日志中数值需除以 10 换算为摄氏度，即 23.2°C -> 24.1°C，但考虑到夏季和电器发热，若未开空调且长时间无人看管，升温速度过快）。更关键的是，结合独居老人背景，这种夜间持续升温模式不符合自然散热规律。",
    "推理步骤 3: 最关键的证据出现在 02:50，当厨房无人时，厨房灯突然开启 (OnOff.OnOff = True)。虽然灯本身不是火源，但在深夜无人操作的情况下，灯光自动亮起极可能是智能联动误触发，或者是用户试图查看情况但未成功关闭热源（如灶具）的表现。同时，厨房温度在无人状态下继续攀升至 24.1°C（假设单位是 0.1°C，则高达 241°C，这显然是传感器故障或数据单位误解；若按常规 Matter 协议，TemperatureMeasurement.MeasuredValue 通常单位为 0.1°C，即 241.2°C 绝对不可能，应为 24.12°C。然而，即使按 24.1°C 计算，对于独居老人夜间场景，厨房温度持续缓慢爬升且无人干预，加上深夜灯光误触，强烈暗示灶具可能处于意外开启状态或发生了其他热源事件，而烟雾报警器未在日志中报警，可能存在延迟或未被触发。",
    "修正推理：重新审视数据单位。Matter 标准中 TemperatureMeasurement.MeasuredValue 单位通常是 0.1°C。日志中数值如 2274 代表 227.4°C？这在室内是不可能的。或者该设备使用的是毫摄氏度 (mC)？如果是 mC，2274 mC = 22.74°C，这是合理的室温。让我们按 **毫摄氏度 (mC)** 理解：\n- 初始室温 ~22.7°C。\n- 02:10 有人进入厨房。\n- 02:30 人离开，但厨房温度开始显著上升：22.7 -> 23.2 -> ... -> 04:20 达到 24.1°C。\n- 升温幅度：1.4°C 在 2 小时内，对于无人房间来说偏高，尤其是如果窗户关闭且没有空调运行（日志未显示空调状态变化，但通常夜间会关闭）。\n- **关键异常点**：02:50 厨房灯在无人的情况下自动打开。这可能是自动化规则错误，也可能是有人短暂回来又离开，但后续 occupancy 一直为 0。\n- **核心风险**：独居老人 + 夜间 + 厨房温度异常升高趋势 + 灯光异常触发。虽然 24.1°C 看起来不高，但结合“独居老人”和“夜间”，任何非预期的温度变化都可能是火灾隐患的前兆（例如燃气泄漏导致燃烧不充分产生热量，或灶具忘记关小火）。更重要的是，如果这是真实的高温（比如单位确实是 0.1°C 但设备坏了报错了），那就是严重问题。但假设单位是 mC，那么 24.1°C 的升温在无人状态下略显可疑，特别是配合灯光误动。",
    "最终判定逻辑：考虑到独居老人的脆弱性，以及夜间厨房温度持续上升且伴随灯光异常动作，系统应将其视为潜在的火灾前兆或设备失控（unattended cooking risk leading to fire risk）。即使温度数值看似温和，趋势和上下文（深夜、无人、灯光乱动）构成了高风险信号。",
    "再次确认单位：如果 2274 是 0.1°C，那是 227°C，房子早就烧了。所以肯定是 mC (milli-Celsius)。2274 mC = 22.74°C。04:20 时 2412 mC = 24.12°C。升温 1.4 度/2 小时。对于夏天晚上，如果开了灶具（哪怕是小火），这个升温是正常的。但是，**为什么人在 02:30 离开后，温度还在持续上升直到凌晨 4 点？** 正常人做完饭会关火。持续升温意味着热源未移除。加上 02:50 灯光自动亮起（可能是联动“检测到高温开灯”或者误判有人），这证实了系统检测到了异常热源。因此，威胁类型确认为 fire_risk (源于 unattended cooking)。"

  "key_evidence": [
    "02:10 厨房有人活动后，人员在 02:30 离开，但厨房温度从 22.7°C 持续上升至 04:20 的 24.1°C，显示热源未被关闭。",
    "02:50 在厨房无人状态下，厨房灯自动开启 (OnOff.OnOff = True)，表明系统检测到异常状态并触发了响应，或存在误报联动。",

## 任务
以下是过去 3 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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2"
  ],
  "recommended_actions": [

}
```

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。

  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常作息规律，门锁操作符合进出习惯，无入侵或异常行为迹象。",
  "reasoning": [
    "门锁状态分析：入户门锁 (front_door_lock) 在每天早晨 (约 07:20-08:26) 和晚上 (约 20:46-20:53) 有规律的解锁/上锁操作，且伴随玄关运动传感器 (entrance_occupancy) 的触发，符合老人起床出门和晚间归家的正常行为模式。",
    "室内活动分析：卧室 (bedroom) 和客厅 (living_room) 的运动传感器在白天时段持续检测到有人 (Occupancy=1)，夜间时段转为无人，与独居老人的睡眠和活动时间吻合，未发现长时间无人却室内温度异常升高（排除火灾风险）或深夜异常活动（排除入侵）。",
    "环境数据一致性：各房间温度传感器读数稳定（客厅约 25°C，卧室约 24°C），厨房灶具未报告高温或烟雾报警，漏水传感器无异常触发，所有设备状态逻辑自洽，无传感器故障或漂移迹象。"
  ],
  "key_evidence": [
    "front_door_lock 在每日固定时间段（早晨和傍晚）出现 LockState 变化，且前后均有 entrance_occupancy 事件支持。",
    "bedroom_occupancy 和 living_room_occupancy 的状态变化与时间轴高度一致，呈现典型的单人居住昼夜节律。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期检查老人健康状态，若连续多日出现类似‘白天仅在卧室’的模式可结合其他健康指标关注。"

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。

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。

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。

请从下面的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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",

  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:20，此时独居老人通常处于睡眠状态（非活动时间）。在此期间，所有房间（包括客厅、卧室、卫生间、玄关）的运动传感器均报告 Occupancy = 0，确认屋内无人。",

    "推理步骤 3: 异常模式识别。对于独居老人家庭，凌晨时段厨房灯光自动开启且伴随无人的高温环境，极大概率是灶具（cook_surface）被意外开启或故障导致加热。考虑到 Matter 协议中温度值通常为整数乘以 10（即 2414 代表 241.4°C 或 24.14°C，结合室温背景，此处数值明显高于正常室温，若按摄氏度理解则已接近危险阈值；即便按毫摄氏度理解，短时间内上升 9 度也远超自然散热速率），这种“无人 + 开灯/热源 + 快速升温”的组合是典型的未受监控烹饪或电器故障导致的火灾前兆。",
    "推理步骤 4: 风险评估。厨房烟雾报警器虽然存在，但在温度急剧上升阶段未见报警记录（可能是尚未触发阈值或日志截断），但这不能排除风险。对于独居老人，夜间厨房起火后果极其严重，必须视为最高优先级威胁。"

    "02:50:00 发生 kitchen_light 开启事件，紧接着温度继续异常爬升，表明有热源在工作。",
    "温度变化速率过快（约 2 小时升温近 10 度），不符合自然环境温度波动规律，符合加热设备运行特征。"

    "立即远程通知住户或其紧急联系人，告知可能存在厨房火险。",

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "老人连续多天活动范围缩小",
  "reasoning": [
    "推理步骤1: 活动由多房间收缩到单一区域",
    "推理步骤2: 跨天持续出现",
    "推理步骤3: 提示功能退化或健康问题"
  ],
  "key_evidence": [
    "活动由多房间收缩到单一区域",
    "跨天持续出现",
    "提示功能退化或健康问题"
  ],
  "recommended_actions": [
    "判定为老人活动范围异常缩小，建议关注健康状态。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式稳定，设备运行正常，未发现安全威胁或异常行为。",
  "reasoning": [
    "时间序列分析：所有事件（起床、出门、做饭、活动）均发生在合理的白天时间段（07:00 - 12:35），符合独居老人的正常作息规律，无深夜异常活动或长时间失联。",
    "空间逻辑一致性：运动传感器和温度传感器的触发顺序合理。例如，入户门解锁后玄关检测到有人，随后客厅和厨房依次被占用；卧室在早晨有短暂离开迹象但很快返回，符合老人起床上厕所或活动的习惯。",
    "环境参数正常：室内温度读数（如 living_room_temp_sensor 的 2526-2545 mK，即约 25.2-25.4°C）处于舒适且安全的范围内，未出现过热或过冷导致的设备故障或健康风险信号。",
    "设备状态健康：门锁操作均为手动且伴随正常的进出记录，无非法入侵尝试；烟雾报警器和漏水传感器未触发警报，表明无火灾或漏水隐患。"
  ],
  "key_evidence": [
    "连续三天（7/4-7/6）的活动摘要数据高度一致，显示稳定的生活节奏。",
    "关键事件链完整：[08:34] 前门解锁 -> [08:39] 玄关有人 -> [08:44] 客厅有人 -> [08:48] 厨房有人，逻辑连贯。",
    "温度传感器数值稳定在 25°C 左右，无剧烈波动或超出安全阈值的情况。"
  ],
  "recommended_actions": [
    "继续保持当前的监控频率，无需额外干预。",
    "建议定期（如每周）检查一次烟雾报警器和电池电量，确保应急设备完好。",
    "鉴于住户为独居老人，可考虑在现有基础上增加一次远程视频通话确认其精神状态（非紧急情况下）。"
