## 任务
监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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",

  ],
  "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": [
    "1. 回家行为分析：20:02 门锁状态变为锁定(LockState=2)，20:03 门磁传感器显示门关闭(BooleanState=False)，随后20:04 玄关灯开启(OnOff=True)。这一序列（开锁/进门 -> 关门 -> 开灯）是典型的归家流程，且时间（20:00左右）对于独居老人来说是合理的晚间活动时间。",
    "2. 室内活动连续性：从18:32开始，玄关运动传感器多次触发，随后19:19至20:03期间，卧室、客厅、厨房、卫生间的运动传感器均有活跃记录。这表明住户在回家后一直在屋内不同房间之间移动，没有长时间静止或异常滞留，排除了跌倒后无法动弹或昏迷的可能性。",
    "3. 排除入侵特征：虽然20:02门锁上锁，但紧接着门磁显示关闭且灯光开启，说明是住户本人操作而非外部强行闯入。此外，全天无烟雾报警、漏水报警或一氧化碳报警等紧急事件触发。"

    "2. 人员活动轨迹合理性：从18:54开始，玄关运动传感器被触发，随后人员依次出现在餐厅、客厅、儿童房、厨房（洗碗机启动）、主卧等区域。这种从入户到分散至各个生活区域的活动路径符合典型的晚间居家生活习惯。",

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，所有设备活动符合正常的家庭作息规律。",
  "reasoning": [
    "1. **作息模式一致性分析**：对比2026-08-10至08-12三天的日志，住户的起床时间（主卧/客厅 occupancy 变为 1）均集中在早晨 06:00-07:30 之间，且温度传感器读数随日照逐渐上升，符合典型的白天活动模式。夜间（00:00-05:00）各区域 occupancy 均为 0，表明住户处于睡眠状态，无异常闯入迹象。",
    "2. **厨房安全行为正常**：虽然 08-11 和 08-12 早上有灶具开启或灯光操作，但随后不久（如 08-11 07:21 开窗通风，08-12 06:42 开灯后无长时间无人看管记录）即有相应的环境调整动作，且未见烟雾报警器触发或长时间无人烹饪导致的过热风险。特别是 08-11 在灶具使用后打开了厨房窗户，这是良好的安全习惯。",
    "3. **门锁与出入记录逻辑自洽**：08-10 早上 07:10 有人手动解锁并离开（LockState 变化），08-11 早上 07:32 有人手动上锁并进入（LockState=1, Entrance Occupancy=1）。这些时间点与住户起床后的活动时间吻合，属于正常的离家/回家行为，不存在暴力破解或异常频繁开关门的迹象。",
    "4. **传感器数据稳定性**：温度传感器数值在合理范围内波动（约 24°C - 25°C），没有出现突变的极端值或长期停滞不前的“卡死”现象，排除了传感器故障导致误报的可能性。"
  ],
  "key_evidence": [

    "推理步骤 2: 在窗户打开期间及之后，厨房和客厅的温度传感器读数急剧上升（从约 24°C 升至 25.3°C+），这种升温速率远超正常环境变化，暗示有热源持续作用或通风不良导致热量积聚。",
    "推理步骤 3: 虽然住户随后锁门离开，但‘烹饪时开窗’结合‘高温报警’是典型的火灾隐患模式（可能涉及燃气泄漏遇明火、油烟起火或设备过热）。相比之下，其他房间活动正常，排除了入侵或尾随的可能性。"

## 任务
请从下面 3 天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": [
    "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": "未检测到安全威胁或异常模式，所有设备日志符合正常住户作息规律。",
  "reasoning": [
    "1. **作息规律性分析**：对比8月2日、3日、4日的活动摘要（Living Room活跃度分别为194, 114, 110），虽然8月2日白天活跃度较高，但结合时间窗看，主要活动集中在早晨6:30-7:30的起床准备阶段（卧室灯亮、浴室占用、门锁操作），随后客厅 occupancy 在上午8点归零，符合住户出门上班/外出的典型行为模式。",
    "2. **关键事件逻辑验证**：8月3日07:20左右，记录到 bedroom_light 关闭 -> front_door_lock 解锁(2) -> front_door_contact 开启(True) -> front_door_lock 上锁(1)。这一序列清晰地表明住户离开家并锁门，属于正常的离家行为，而非入侵或非法进入。",
    "3. **传感器数据合理性**：温度传感器读数（如2448代表24.48°C）随时间缓慢变化，且夜间无人员活动时温度稳定，有人活动时略有波动，未见跳变或停滞，排除传感器故障。Occupancy传感器在夜间为0，清晨依次唤醒，符合人体感应逻辑。",
    "4. **无危险迹象**：厨房灶具(cook_surface)和烟雾报警器(smoke_co_alarm)在日志期间未触发任何报警或异常状态；门窗传感器仅在正常出入时触发；无漏水或一氧化碳风险迹象。"
  ],
  "key_evidence": [
    "8月3日07:20:21至07:20:28，门锁状态从解锁变为锁定，伴随门磁打开后关闭，确认为正常离家锁门行为。",
    "连续三天早晨06:30-07:30期间，卧室、浴室 occupancy 活跃及灯光开启，随后客厅 occupancy 在08:00左右归零，呈现一致的晨间起床与离家模式。",
    "温度传感器数值在合理范围内（约23-25°C）平滑变化，无突变或死值。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则（如离家自动关灯/关空调），以优化能源使用。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "触发时间位于清晨起床窗口且有轻微抖动，不是固定的可疑重复模式。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}


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。

    "1. 活动模式分析：日志集中在清晨 06:00-07:30 之间，各房间（主卧、儿童房、客厅、餐厅）的运动传感器依次触发，符合家庭成员起床、洗漱、准备早餐和出门的常规作息规律。",
    "2. 厨房灶具状态检查：虽然日志中出现了 `kitchen_cook_surface` 的状态变化（如 07:18 关闭），但并未伴随烟雾报警器报警或温度异常飙升。且灶具在开启后短时间内即关闭，随后有灯光操作，符合正常烹饪或烧水行为，未发现无人看管导致的火灾风险。",
    "3. 门锁与安防状态：入户门传感器和门锁仅在 07:36 出现一次关闭/上锁记录，这与早晨家人出门上班或送孩子上学的场景完全吻合，无非法入侵迹象。",
    "4. 传感器数据合理性：温度读数随时间缓慢上升（从 ~24°C 升至 ~25°C+），符合室内环境温度随日照或空调停止运行后的自然变化趋势，无传感器故障或漂移迹象。"

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": [
    "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",

  "threat_description": "未检测到安全威胁或异常模式，日志显示为正常的家庭日常活动及环境监控数据。",
  "reasoning": [
    "1. 重点设备行为分析：在 17:20，阳台门传感器状态变为 False（通常表示关闭/闭合），同时阳台灯开启。这符合住户进入阳台或整理物品时的正常交互逻辑，且随后洗衣机启动（17:21），表明有人正在使用阳台区域进行洗衣相关活动，行为连贯且合理。",
    "2.  occupancy 分布合理性：日志中主卧、儿童房、玄关和餐厅的运动传感器持续显示 Occupancy=1，而客厅和次卧显示 Occupancy=0。这种分布符合典型的傍晚时段家庭活动模式（如孩子在房间学习/玩耍，大人在卧室休息或准备晚餐，玄关有人员进出迹象），未发现长时间无人却频繁触发或长时间有人却无互动的异常情况。",
    "3. 温度数据稳定性：所有温度传感器的读数在 23.3°C - 23.8°C 之间波动，变化幅度极小且符合室内恒温环境的特征，没有突变的极端值，排除了传感器故障或火灾风险。",
    "4. 无关键安全事件：日志期间未出现烟雾报警、漏水检测、门锁异常开启或非法入侵的迹象。"
  ],
  "key_evidence": [
    "17:20 balcony_door_contact=False 与 17:20 balcony_light=True 同步发生，随后 17:21 laundry_washer 启动，构成完整的用户行为链。",

请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

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",

    "2. 人员活动轨迹符合常理：运动传感器在客厅、餐厅、主卧、儿童房等区域有规律地触发，且存在明显的“有人”到“无人”再到“有人”的切换，表明家庭成员在家中正常移动，无长时间静止不动导致的跌倒风险或异常静默。",
    "3. 无危险设备状态：日志中未涉及厨房灶具、烟雾报警器、漏水传感器等关键安全设备的报警或异常状态，排除了火灾、燃气泄漏或水浸风险。",
    "4. 光照控制逻辑一致：14:06 玄关灯开启紧随门锁操作之后，可能是自动化场景触发或手动补光，属于正常家居交互，未发现非法入侵后的异常照明模式。"

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。
