## 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",

    "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。

    "环境安全监测：客厅温度传感器读数在 24°C-26°C 之间波动，属于夏季正常室温范围；厨房和卧室温度传感器数据合理且与 occupancy 状态匹配，未出现高温报警或传感器漂移导致的误报。",
    "安防系统验证：入户门锁状态正常，仅在预期出门时解锁（LockState=2），进门时接触传感器正确触发（StateValue=False 表示开门动作完成），无非法闯入或锁具故障迹象；烟雾报警器未触发任何事件。",
    "设备逻辑一致性：所有运动传感器（occupancy）的触发均伴随相应的温度变化或灯光控制（如 living_room_light 开启），设备间联动逻辑正常，排除了传感器卡死或恶意干扰的可能性。"
  ],
  "key_evidence": [
    "连续三天起床和活动高峰时间窗重合度极高（06:25-09:30），表明生活习惯稳定。",
    "入户门锁仅在 08:33 (Aug 3) 和 08:28 (Aug 4) 等明确外出时段解锁，且随后立即检测到门口有人进入，逻辑闭环完整。",
    "所有温度传感器数值均在合理物理范围内（2400K-2550K ≈ 21°C-22.5°C 至 25°C-26°C，注：Matter 协议常以毫开尔文为单位，此处换算后为常温），无超温报警。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期（如每月）检查老人身体状况，确保其日常生活自理能力稳定。",
    "确认智能家居系统固件为最新状态，以维持 Matter 协议下的设备兼容性。"

## 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": [
    "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。

  "threat_description": "过去三天的设备日志显示独居老人的活动模式稳定，符合正常的晨间起床、洗漱、早餐及日间活动的规律，未发现入侵、异常停留或设备故障迹象。",
  "reasoning": [
    "时间序列分析：日志记录的时间点（06:25-09:50）与独居老人典型的起床、如厕、准备早餐及在客厅/厨房活动的时间高度吻合，跨天数据（7 月 6 日 -8 日）显示作息非常规律，无突变。",
    "空间行为逻辑：运动传感器和温度传感器的变化呈现合理的空间转移路径（卧室 -> 卫生间 -> 玄关 -> 厨房 -> 客厅），且各房间 occupancy 状态切换自然，不存在长时间无人却温度剧烈波动等矛盾现象。",
    "设备状态验证：入户门锁仅在 08:35 出现一次手动上锁操作，随后有人员进出记录，符合正常生活场景；所有传感器读数（温度、占用状态）均在合理范围内，未见 stuck（卡死）或 drift（漂移）导致的误报。"
  ],
  "key_evidence": [
    "连续三天（7 月 6 日 -8 日）的起床时间（约 06:25-06:53）和活动顺序完全一致，表明这是该住户的稳定习惯。",
    "08:35 的 door_lock 手动上锁事件紧随 entrance_occupancy=1 之后，且后续仍有 kitchen/living_room 的活动记录，证明是住户正常出门前的关门行为，而非入侵者闯入。",
    "温度传感器数据（如 living_room_temp_sensor 从 24.9°C 升至 25.5°C）随人员进入和空调运行呈线性变化，符合物理规律，排除了传感器故障。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期查看历史日志以确认长期模式的稳定性，作为未来异常检测的基线。"

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
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": [

    "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": "behavioral_anomaly",
  "threat_description": "连续多天不使用厨房",
  "reasoning": [

}

```json

  "threat_type": "none",
  "threat_description": "日志显示正常的家庭日常活动模式，包括起床、离家锁门及室内温度调节，未发现安全威胁或异常行为。",
  "reasoning": [
    "时间序列分析：所有事件均发生在合理的作息时间内（06:00-10:00），符合典型的起床和出门流程，无深夜或非正常时段的活动。",

    "环境数据合理性：温度传感器读数（如 2485 mK ≈ 24.85°C）在正常居住舒适范围内，且随空调/窗户状态有合理波动； occupancy 传感器在无人时段（如夜间 00:00-06:00）持续报告 0，与跨天摘要中的低计数一致，传感器工作正常无漂移或卡死。",
    "设备联动正常：卧室灯关闭发生在人员离开后，厨房温度上升伴随可能的烹饪活动（灶具虽未直接触发高温报警，但温度变化趋势自然），整体设备交互符合预期的人类行为习惯。"
  ],
  "key_evidence": [
    "2026-08-03T07:38: front_door_contact -> False 紧接着 front_door_lock -> 1 (Locked)",

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
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: ...",

    "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": "behavioral_anomaly",
  "threat_description": "回家后跳过常规过渡行为直接进卧室",
  "reasoning": [

    "推理步骤2: 直接切到卧室活动",
    "推理步骤3: 偏离既往居家路径"
  ],
  "key_evidence": [
    "入户后缺少常见过渡动作",

    "偏离既往居家路径"
  ],
  "recommended_actions": [

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的家庭晚间活动模式，无安全威胁或异常行为。",
  "reasoning": [
    "时间线分析：日志从凌晨 00:00 到晚上 19:40，所有房间（客厅、主卧、次卧、厨房等）的运动传感器在大部分时间段均报告 Occupancy = 0，符合夜间及傍晚无人活动的正常状态。",
    "温度数据合理性：虽然温度值以毫摄氏度（mK）为单位（例如 2382 mK ≈ 23.82°C），但数值变化平稳且符合物理规律。从下午的约 23.8°C 逐渐下降至晚上的约 22.7°C，随后略有回升，这是典型的室内空调运行后自然降温及环境热交换过程，未见突变或漂移。",
    "关键事件逻辑验证：18:20 入户门接触传感器变为 False（开门），紧接着 18:21 客厅灯开启，18:22 主卧有人进入。这一序列完全符合住户下班回家、进门开灯、进入卧室的正常生活场景，不存在尾随入侵或非法闯入的迹象。",
    "设备状态一致性：所有传感器和致动器响应及时，无卡死、延迟或数据丢失现象，系统运行稳定。"
  ],
  "key_evidence": [
    "18:20 front_door_contact 变为 False 后立即伴随 living_room_light_1 开启和 master_bedroom_occupancy 变为 1，形成完整的‘进门 - 开灯 - 入内’逻辑链。",
    "全时段运动传感器读数与温度传感器读数相互印证，未发现传感器故障导致的矛盾数据（如有人但温度剧烈波动，或无人但温度异常升高）。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统运行正常。",
    "建议继续保持对入户门锁和运动传感器的监控，作为日常安全基线。"
  ]
}

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
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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2"
  ],
  "recommended_actions": [
    "建议措施1",

}
```

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: 正常行为分析显示，住户于 18:05 返回家中并开启空调，随后在 19:00 开启厨房灯光，19:03 开启灶具 (cook_surface)，这是典型的晚间烹饪场景。",
    "推理步骤 2: 随着灶具开启，厨房温度应逐渐上升。日志显示从 19:00 到 19:20，厨房温度读数从 2366 持续上升至 2610（对应约 43.7°C），符合物理规律。",
    "推理步骤 3: 关键异常发生在 19:01 至 19:15 期间。当灶具开启且环境温度理应升高时，厨房温度传感器读数突然剧烈波动：先变为 None (19:01)，随后跳变至 2418 (约 40.3°C)，并在短时间内飙升至 2554、2610 等远超合理范围的数值（若按摄氏度计则已发生严重过热，若按毫开尔文换算也超出常规室温变化幅度）。",
    "推理步骤 4: 与此同时，客厅和卧室的温度传感器读数稳定且合理（约 22-23°C），表明其他传感器工作正常。这种单一传感器的极端异常排除了环境整体过热的可能性，确认为传感器故障或校准失效。",
    "推理步骤 5: 由于该传感器负责监测厨房这一高风险区域，其失灵可能导致烟雾报警器未能及时联动或用户无法通过远程监控得知真实火情，构成潜在的安全隐患。"

    "在同一时间段内，客厅和卧室温度传感器读数保持稳定（~2200-2300），证明环境未发生全局性剧变，故障局限于厨房传感器。",
    "事件时间线与 19:03 开启灶具的操作高度相关，但温度读数的突变模式不符合正常的热传导曲线。"
  ],
  "recommended_actions": [

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。

## 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",

    "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。

    "设备状态一致性：所有温度读数（约 23°C）处于正常舒适范围，无过热或骤降；烟雾报警器未触发；漏水传感器无报警。虽然 18:25 厨房温度传感器短暂报空值 (None) 后恢复，但这属于常见的通信丢包或重启现象，且不影响后续读数，不构成故障。",
    "结论：整个序列展示了完整的‘归家 - 生活 - 烹饪’闭环，没有检测到尾随进入、非法闯入、火灾风险或设备卡死等异常模式。"
