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 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",

    "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": "老人用餐时间逐步推迟",
  "reasoning": [

    "提示作息漂移异常"
  ],
  "recommended_actions": [
    "标记为作息异常漂移，建议结合健康状况进一步关注。"
  ]
}

```json
{

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人生活规律，设备状态与时间、活动模式高度一致，未发现安全威胁或异常行为。",
  "reasoning": [
    "时间逻辑合理：厨房灯光开启事件（如 05:56, 12:05, 16:40）均发生在有厨房占用记录之后或同时，符合正常烹饪或准备食物的行为模式，不存在无人看管烹饪的迹象。",
    "温度数据正常：所有房间的温度传感器读数（例如客厅 25°C 左右，卧室 23-24°C 左右）均在舒适且安全的范围内，无过热（火灾风险）或过冷（健康风险）的漂移现象。",
    "活动模式连贯：运动传感器和占用传感器的触发时间与门窗开闭、灯光变化等事件在空间和时间上紧密关联，反映了住户正常的日常流动轨迹，未见长时间静止不动（跌倒风险）或异常频繁进出（入侵迹象）。",
    "设备响应正常：窗帘、门锁等执行器仅在检测到人员活动时响应，未出现卡死或误动作；烟雾报警器等安全设备未触发警报，环境指标稳定。"
  ],
  "key_evidence": [
    "厨房灯光开启严格跟随厨房占用信号，无延迟或无占用的情况。",
    "全天各房间温度波动范围小（<5°C），且数值处于人体舒适区间。",
    "入户门传感器与玄关/客厅运动传感器在早晚时段呈现规律的进出对偶关系。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，定期查看日志摘要。",
    "建议家属或照护者按原计划进行常规电话问候，确认老人精神状态良好。"

## 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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "夜间长期停留在非卧室区域",
  "reasoning": [
    "推理步骤1: 深夜在非卧室区域持续活动",
    "推理步骤2: 时长明显超出普通起夜",
    "推理步骤3: 可能是迷路或意识混乱"
  ],
  "key_evidence": [
    "深夜在非卧室区域持续活动",
    "时长明显超出普通起夜",
    "可能是迷路或意识混乱"
  ],

  "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温度异常升高，存在严重的火灾隐患。",
  "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 04:15，此时所有房间（包括客厅、卧室、卫生间、玄关）的运动传感器均报告 Occupancy = 0，确认屋内无住户活动。",
    "推理步骤 2: 设备状态异常。尽管厨房无人，但厨房温度传感器读数从 02:10 的 23.75°C (2375 mK) 持续攀升至 04:15 的 24.02°C (2402 mK)，并在 03:10-03:40 期间达到峰值约 23.85°C-23.88°C。对于独居老人家庭，夜间厨房温度异常升高通常意味着灶具或电器未关闭。",
    "推理步骤 3: 关联事件验证。虽然厨房灯在 02:50 开启过，但这可能是误报或自动感应，无法解释长达两小时的持续升温。更关键的是，厨房烟雾报警器在整个时间段内未触发报警，这可能意味着烟雾尚未产生（处于起火前兆阶段），或者传感器本身存在问题，但仅凭温度趋势已足以判定为高风险。",
    "推理步骤 4: 风险评估。独居老人在睡眠中若发生厨房火灾，极易造成严重后果。这种‘无人 + 高温持续上升’的模式是典型的未关火/电器故障导致的火灾风险特征。"
  ],

    "厨房温度在凌晨时段出现非正常的线性上升趋势，且持续时间超过 2 小时，远超正常环境波动范围。",
    "在此高温持续期间，厨房烟雾报警器未发出警报，提示可能存在未被检测到的阴燃风险或设备故障。"
  ],
  "recommended_actions": [
    "立即远程通知家属或紧急联系人，告知厨房可能存在的火灾隐患。",
    "尝试通过 Matter 协议远程检查并关闭厨房灶具或相关加热设备（如果权限允许）。",
    "建议物业或安保人员尽快上门检查厨房状况，确认是否有明火或过热设备。",
    "检查厨房烟雾报警器和温度传感器的校准状态，确保其正常工作。"

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 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",

    "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": [

  ]
}

```json
{

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式稳定，无入侵、火灾或设备故障迹象，环境安全。",
  "reasoning": [
    "入住与离开时间规律：住户每天在早上 07:20-08:30 之间起床并进入客厅/厨房，晚上未在日志中显示长时间未归（截至 12:00 仍在卧室），符合独居老人白天活动的正常节奏。",
    "多房间联动逻辑正常：当 entrance_occupancy 和 front_door_contact 触发时，living_room_occupancy 随后变为 1，表明住户从玄关自然移动至客厅，不存在门开后无人进入的异常尾随或入侵迹象。",
    "温度数据合理且一致：所有温度传感器读数（如 living_room_temp_sensor 的 2517-2559 mK，即约 24.2°C - 24.6°C）均在舒适范围内，且数值随时间有微小波动但无突变，排除了传感器漂移、故障或火灾风险。",
    "无关键安全事件：日志中未出现烟雾报警器 (smoke_co_alarm)、漏水传感器 (water_leak_detector) 或门锁状态异常 (lock_malfunction) 的报警记录，也未发现长时间无生命体征的异常静默期。"
  ],
  "key_evidence": [
    "front_door_contact 状态变化后紧接着 entrance_occupancy 和 living_room_occupancy 激活，行为连贯。",
    "连续三天 (Aug 8-10) 的温度读数稳定在 24°C 左右，无极端高温或低温报警。",
    "卧室 occupancy 在夜间及清晨持续为 1，直到上午 07:20-08:00 间才出现短暂 0 或与其他房间活动同步，符合睡眠后起床模式。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期检查独居老人的健康状态，确保其日间活动量符合预期。"

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",

  ],
  "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": [
    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:10，属于独居老人的夜间睡眠时段。在此期间，所有房间（包括客厅、卧室、卫生间、玄关）的运动传感器均持续报告 Occupancy = 0，确认屋内无人。",
    "推理步骤 2: 设备状态异常分析。厨房运动传感器在 02:10 短暂报告为 1（可能为误报或宠物/老鼠），但在 02:35 再次报告为 1 后，从 02:50 开始持续报告为 0。然而，厨房温度传感器读数却呈现持续且剧烈的上升趋势：从 02:10 的 23.34°C (2334 mK) 一路攀升至 04:10 的 24.15°C (2415 mK)，增幅接近 8°C。",
    "推理步骤 3: 威胁关联与排除。虽然厨房灯在 02:50 开启，但仅开灯通常不会导致室温在短时间内急剧上升 8 度。结合‘无人’和‘高温’两个关键特征，最可能的原因是灶具（cook_surface）处于开启加热状态但未有人看管，或者发生了其他热源故障。对于独居老人而言，夜间无人看管的烹饪是典型的火灾隐患。",
    "推理步骤 4: 结论。尽管烟雾报警器未触发报警（可能是阈值未到或尚未达到烟雾浓度），但温度的异常飙升已构成明确的‘无人看管烹饪’导致的火灾风险（unattended_cooking/fire_risk）。"

    "同一时间段内，全屋（含厨房）运动传感器绝大多数时间为 0，表明无人在场进行干预。",
    "厨房灯光在 02:50 开启，但不足以解释如此大幅度的温升，暗示有更强的热源（如灶具）在工作。"
  ],
  "recommended_actions": [
    "立即远程通知住户或其紧急联系人，告知厨房可能存在过热或无人看管烹饪的情况。",
    "检查并重置厨房烟雾报警器，确保其处于正常工作状态。",

    "安排社区工作人员或邻居上门查看情况，以防发生火情。"

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
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",
  "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": "behavioral_anomaly",
  "threat_description": "出门频率突然下降",
  "reasoning": [
    "推理步骤1: 首日仍有出门链路",
    "推理步骤2: 后续明显缺少外出相关事件",
    "推理步骤3: 可能反映社交/功能退缩"
  ],
  "key_evidence": [
    "首日仍有出门链路",
    "后续明显缺少外出相关事件",
    "可能反映社交/功能退缩"
  ],
  "recommended_actions": [
    "标记为出门频率异常下降，建议结合老人状态持续观察。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "过去三天的设备日志显示独居老人的日常活动模式稳定，无入侵、异常操作或设备故障迹象。",
  "reasoning": [
    "入住与出门时间规律：老人每天约在 07:29-08:09 之间起床（卧室 occupancy 变为 1），并在 08:35-09:00 之间离开家（门锁解锁/开门，前门接触传感器状态变化），且每日重复此模式，符合正常作息。",
    "室内活动逻辑自洽：当老人进入厨房或客厅时，对应房间的运动传感器和温度传感器均有响应；离开后传感器状态随之改变，未发现人员滞留或传感器卡死现象。",
    "安全设备工作正常：烟雾报警器、漏水传感器等未触发报警事件；门锁操作记录显示均为手动正常开锁/上锁，无非法尝试或锁定失败记录。"
  ],
  "key_evidence": [
    "连续三天 (2026-08-21 至 2026-08-23) 的起床和出门时间高度一致，表明行为模式稳定。",
    "所有运动传感器（occupancy_sensor）的状态变化与温度传感器（temperature_sensor）及灯光设备的激活时间吻合，排除了传感器漂移或故障。",
    "入户门锁（front_door_lock）仅在预期出门时间被操作，且随后前门接触传感器（front_door_contact）正确报告开门状态，无异常闯入痕迹。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期（如每周）检查一次烟雾报警器和漏水传感器的电池电量及功能测试，确保长期可靠性。"
