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: ...",
    "推理步骤3: ..."
  ],

    "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": "日志显示独居老人在两天内的活动模式高度一致，烹饪行为正常（开启后不久即关闭），无未遂火灾、入侵或健康异常迹象。",
  "reasoning": [
    "1. 烹饪行为分析：在7月27日和28日，厨房灶具（kitchen_cook_surface）均在中午时段（约12:00-12:05）开启，并在30分钟内关闭（27日12:22关闭，28日12:28关闭）。这种‘开启-烹饪-关闭’的闭环行为符合正常的做饭习惯，未发现长时间无人看管导致的火灾隐患（unattended_cooking）。",
    "2. 环境与安全联动：尽管灶具开启，但厨房烟雾报警器（smoke_co_alarm）和漏水传感器（water_leak_detector）在整个日志期间均未触发报警，表明没有发生实际的火灾或泄漏事故。",
    "3. 活动规律性对比：两天的跨天活动摘要数据显示，各房间的活动计数非常稳定（如living_room分别为211和209，kitchen均为242），且关键设备事件的时间点（如温度上报、 occupancy 变化）在两天间具有极高的相似性。这种高度的重复性排除了突发性的行为异常（behavioral_anomaly）或老人失能/跌倒（possible_fall）的可能性，因为如果是异常情况，通常会导致活动模式的剧烈波动或长时间静止。",
    "4. 传感器状态检查：温度传感器读数随时间自然波动，无跳变或卡死现象；运动传感器在人员活动时正确上报Occupancy=1，离开后或在非活跃期无异常持续占用，表明传感器工作正常，无故障（sensor_malfunction）。"
  ],
  "key_evidence": [
    "7月27日 kitchen_cook_surface 于 12:00 开启，12:22 关闭，时长22分钟，属正常烹饪范围。",
    "7月28日 kitchen_cook_surface 于 12:05 开启，12:28 关闭，时长23分钟，与前一天模式几乎完全一致。",
    "两天内所有 smoke_co_alarm 和 water_leak_detector 均无报警记录。",
    "两天内 living_room 和 kitchen 的活动计数差异极小（<2%），显示生活规律稳定。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",
    "建议定期校准温度传感器以确保读数准确性，但目前看来工作正常。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",

  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]

## 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情况，设备日志显示住户活动规律且符合独居老人的日常作息模式。",
  "reasoning": [
    "1. 活动模式分析：日志显示住户在早晨（07:25-09:30）有规律地从卧室、厨房到客厅活动，随后在白天大部分时间处于非活跃状态（仅偶尔触发传感器），夜间（23:38-23:46）有轻微活动后休息。这种‘早起-日间静默-晚间休息’的模式符合独居老人的典型生活节奏，未发现长时间无活动的健康风险（如跌倒后昏迷）或异常入侵迹象。",
    "2. 门锁与入口安全：入户门仅在 07-15 08:22 有一次手动开锁记录，且随后玄关和客厅传感器随即激活，表明是住户正常出门或回家，而非强行闯入。其他时间门窗传感器未见异常开启报警。",
    "3. 环境与安全设备：温度读数在合理范围内（约24-25°C），无剧烈波动暗示设备故障。虽然日志中未直接显示烟雾报警器触发，但厨房灶具（cook_surface）在日志片段中未出现持续开启而无人员离开厨房的异常组合（即未检测到无人看管烹饪的风险）。所有传感器数据连贯，无明显的‘卡死’或‘漂移’特征。"
  ],
  "key_evidence": [
    "07-13至07-15连续三天，早晨07:30-09:30期间各房间 occupancy 传感器按逻辑顺序激活（厨房->卧室->客厅/玄关），符合起床洗漱准备流程。",
    "07-15 08:22 入户门锁 Manual Unlock 事件后，entrance_occupancy 和 living_room_occupancy 迅速响应，证实为合法用户操作。",
    "夜间时段（23:38-23:46）仅有厨房传感器短暂激活，可能是起夜或喝水，随后无后续异常活动，排除严重安全隐患。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需紧急干预。",
    "建议定期校准温度传感器以确保读数准确性，尽管目前数据看起来正常。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "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": [
    "正常样本仍保持多房间活动；异常样本逐渐收缩到卧室附近。"
  ],
  "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。

## 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",

    "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。

    "2. 人员活动轨迹分析：运动传感器（Occupancy Sensor）在客厅、卧室、厨房、玄关的激活模式呈现典型的“居家”特征。早晨起床（卧室/玄关活动），随后在客厅和厨房有持续的活动记录，夜间无异常的大范围移动或长时间静止不动（排除跌倒风险）。",
    "3. 设备操作逻辑一致性：7月4日 08:26 记录了门锁手动上锁事件 (`LockOperation(LockOperationType=1)`)，这与早晨出门或检查门锁的行为一致，且随后玄关和客厅仍有活动，说明住户在家或刚回家，逻辑自洽，非暴力破解或非法入侵。",
    "4. 环境数据稳定性：温度传感器读数随时间缓慢变化，符合室内热惯性规律，无突变或传感器卡死（Stuck）的迹象。厨房灶具仅在特定时间段开启，未见长时间无人看管的情况。"

    "lock_malfunction 事件 (08:26) 标记为 Manual Lock，属于正常用户操作。",

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",
    "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": "独居老人在凌晨时段出现长时间无活动且室内温度异常升高，存在严重的健康风险或意外滞留风险。",
  "reasoning": [
    "推理步骤 1: 时间分析显示，从 02:18 到 05:28（约 3 小时），卧室灯被打开过但随后在 02:30、03:00、04:00 等多次全屋运动传感器报告无人状态（Occupancy=0）。这表明老人可能处于清醒但未移动的状态，或者已经失去行动能力。",
    "推理步骤 2: 环境数据异常，客厅和厨房的温度传感器读数持续上升（从 22°C 升至 24°C+），而卧室温度也同步缓慢爬升。对于独居老人而言，夜间长时间静止不动伴随室温升高，极有可能是中暑、脱水或突发疾病导致无法调节体温或移动至凉爽区域。",
    "推理步骤 3: 结合住户画像（独居老人），这种“夜间开灯后长时间无位移”加上“环境温度异常”的组合模式，高度符合跌倒后无法起身、突发疾病昏迷或意识模糊的健康危机场景，而非正常的睡眠或休息行为。"
  ],
  "key_evidence": [
    "02:18 开启卧室灯，但在随后的 3 小时内（02:30-05:28）所有房间运动传感器均报告无人，且期间仅有短暂的水龙头占用记录（06:03），暗示老人可能在深夜已无法自主活动。",
    "00:10 至 05:28 期间，客厅及厨房温度持续攀升至 24°C 以上，表明室内缺乏人员流动带来的热交换，且空调未有效运行（日志中未见空调控制指令），加剧了高温风险。",
    "05:28 再次开启卧室灯，距离上次开灯已超过 3 小时，说明老人醒来或有人进入，但中间长达数小时的静默期构成了高危窗口。"
  ],
  "recommended_actions": [
    "立即触发紧急警报通知家属或监护人，并建议联系社区服务中心或急救部门进行上门核查。",
    "检查家中空调系统是否故障或未开启，确保老人苏醒后能迅速获得降温措施。",
    "建议安装或启用带有跌倒检测功能的智能摄像头或雷达传感器，以填补单纯运动传感器对‘静止不动’监测的盲区。"

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: ...",
    "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": 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: 正常样本是短时起夜；异常样本在厨房等非卧室区域停留过久。"
  ],
  "key_evidence": [
    "正常样本是短时起夜；异常样本在厨房等非卧室区域停留过久。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "health_concern",
  "threat_description": "独居老人在凌晨时段出现长时间无活动且室内温度异常升高，存在健康风险或意外滞留的可能性。",
  "reasoning": [
    "推理步骤 1: 时间窗口分析。日志显示在 2026-08-01T00:00:00 至 05:20:06 之间，所有房间（living_room, bedroom, kitchen, bathroom, entrance）的运动传感器持续报告 Occupancy = 0，长达超过 5 小时无任何人员活动迹象。对于独居老人而言，整夜完全无活动属于极度异常的‘静默’模式。",
    "推理步骤 2: 环境状态关联。在此期间，客厅和厨房的温度传感器读数持续上升并达到极高水平（例如 living_room_temp_sensor 从 22.7°C 升至 23.9°C+，kitchen_temp_sensor 甚至达到 23.7°C+）。考虑到空调设备未出现在活跃控制列表中，且温度呈单向上升趋势，这暗示可能缺乏有效降温措施，或者有人体热源但未被运动传感器检测到（如老人静止不动、跌倒或昏迷）。",
    "推理步骤 3: 关键事件缺失。直到 T05:20:06 卧室灯才被打开，此时距离上次任何活动记录已过去 5 个多小时。这种‘长时无人 + 高温累积 + 延迟唤醒’的组合模式，强烈指向老人可能在夜间发生了跌倒、突发疾病导致无法移动，或是因睡眠障碍/意识模糊而长时间未进行正常活动，而非正常的深度睡眠（通常会有翻身等微小动作触发传感器或温度波动）。"
  ],
  "key_evidence": [
    "2026-08-01T00:00:00 至 T05:20:06 期间，全屋所有运动传感器连续 5 小时以上保持 Occupancy=0。",
    "同一时间段内，客厅和厨房温度持续攀升，最高分别达到约 23.9°C 和 23.7°C，且未见空调调节行为。",
    "卧室灯光在 T05:20:06 才首次被开启，表明该时段内住户处于完全无响应状态。"
  ],
  "recommended_actions": [
    "立即通过家庭自动化系统拨打紧急联系人电话或发送警报通知家属/监护人。",
    "若配备远程视频门铃或室内摄像头，尝试查看实时画面确认老人状态。",
    "联系社区急救服务或安排上门探访，以防老人发生意外（如跌倒、中风等）。",
    "检查并校准运动传感器灵敏度，排除因设备故障导致的误报（虽然概率较低，需作为次要排查项）。"
