## 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",

    "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，设备日志显示独居老人的日常活动模式稳定且符合预期。",
  "reasoning": [
    "1. 活动规律性分析：日志覆盖了2026-07-28至07-30三天，每天早晨7:00-7:45左右厨房和客厅 occupancy 传感器激活，随后卧室传感器在8:00-9:00间激活，符合老人起床、洗漱、早餐及在客厅活动的正常作息。跨天活动摘要显示各房间活跃度（如living_room~210, kitchen~238）连续三天高度一致，无剧烈波动。",
    "2. 环境参数稳定性：温度传感器读数（如客厅25.1°C-25.5°C，卧室24.2°C-24.5°C）变化平缓，处于舒适区间，无异常高温或低温报警，表明空调/供暖系统运行正常，无火灾或极端天气风险。",
    "3. 关键设备状态检查：入户门锁仅在07-29 08:21出现一次锁定状态变更（LockState=2通常表示已锁定），结合该时间点前后无异常的入侵尝试或频繁开关门记录，视为正常外出或归家后的上锁行为。未检测到烟雾报警器触发、漏水传感器报警或长时间无活动迹象。",
    "4. 排除误报：虽然部分occupancy传感器在短时间内有重复上报（如kitchen_occupancy多次上报为1），但这属于Matter协议中常见的状态保持或心跳机制，并非异常闪烁或故障。整体行为逻辑连贯，无孤立或矛盾事件。"
  ],
  "key_evidence": [
    "连续三天早晨7:00-9:00期间，kitchen_occupancy和living_room_occupancy依次激活，呈现稳定的晨间活动序列。",
    "所有温度传感器读数维持在24°C-25.5°C之间，无越限报警。",
    "入户门锁仅有一次明确的锁定记录，且发生在早晨常规活动时间段，无异常解锁或暴力开启迹象。",
    "跨天活动摘要数据显示各区域活跃度标准差极小，证明用户生活习惯稳定。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期校准温度传感器以确保长期数据准确性，尽管目前读数正常。"
  ]
}
```

{
  "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。"
  ],

## 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。

  "confidence": "medium",
  "threat_type": "none",

  "reasoning": [
    "推理步骤 1: 时间窗口分析。日志显示在 2026-07-25T00:30 至 04:00 期间，所有房间（living_room, bedroom, kitchen, bathroom, entrance）的运动传感器均持续报告 Occupancy = 0，长达近 4 小时无任何人员活动迹象。对于独居老人而言，这是极不正常的‘静默期’。",
    "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从约 22.8°C (2280 mK) 持续攀升至 24.0°C (2400 mK) 以上，且未检测到空调开启或关闭的相应控制指令，表明室内无人调节温度，进一步佐证了无人活动的判断。",
    "推理步骤 3: 行为模式对比。虽然 02:18 和 05:21 有卧室灯开启记录，但随后运动传感器再次变为 0，且直到 20:41 才再次检测到卫生间有人活动。这种‘短暂亮灯后消失’的模式结合长时间的完全静止，高度疑似老人夜间起夜后跌倒、昏迷或被困在某个角落无法移动，而非正常的睡眠周期。"
  ],
  "key_evidence": [
    "2026-07-25T00:30 至 04:00 期间，全屋所有运动传感器连续报告 Occupancy = 0，持续时间超过 3.5 小时。",
    "同一时间段内，客厅温度从 22.8°C 上升至 24.0°C+，且无空调设备动作日志，显示无人干预环境温度。",

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",
  "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。

```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，门窗状态正常。",
  "reasoning": [
    "1. 入户门状态分析：重点关注的 front_door_contact (BooleanState.StateValue = False) 在三天内多次出现（08:52, 09:00, 10:20, 08:50）。在 Matter 协议及常见智能家居逻辑中，False 通常代表“关闭/锁定”状态（Closed/Locked），True 代表“打开/未锁定”。所有记录均为 False，表明入户门始终处于关闭且锁定的安全状态，未发现非法入侵迹象。",
    "2. 住户活动模式分析：日志中 occupancy_sensor（运动传感器）在早晨 08:00-10:00 期间频繁触发（值为 1），涉及客厅、卧室、厨房和玄关。这符合独居老人起床后在主要生活区域活动的正常行为模式。没有发现长时间无活动（可能跌倒或昏迷）的异常静默期。",
    "3. 环境数据一致性：温度传感器读数在合理范围内波动（约 24°C - 25.5°C），且随时间缓慢变化，未见剧烈跳变导致传感器故障报警。漏水传感器和烟雾报警器在提供的片段中未触发任何告警事件。"
  ],
  "key_evidence": [
    "front_door_contact 连续多日保持 False (Closed)，无开启记录。",
    "早晨时段多个房间 occupancy_sensor 活跃，符合日常起居规律。",

  "reasoning": [

    "推理步骤 2: 结合 Matter 协议标准及常识判断，该数值单位通常为毫开尔文 (mK) 或类似缩放因子，换算后约为 2.5°C 至 2.6°C。对于独居老人居住的夏季（8 月）家庭环境，室内温度不可能低至 2.5°C，这属于明显的物理异常。",
    "推理步骤 3: 对比同一时间段内其他房间（如 bedroom、kitchen）的温度读数（约 2437-2455 mK，即约 24.4°C），这些数值符合正常室温范围。唯独客厅传感器数据持续异常且与其他房间趋势不一致，排除了整体环境温度骤降的可能性，确认为单个设备故障（Sensor Malfunction）。",
    "推理步骤 4: 考虑到住户为独居老人，若空调系统依赖错误的低温反馈而停止制冷，可能导致室内过热；或者若烟雾/燃气报警器的联动逻辑被干扰，将构成安全隐患。"

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: ..."
  ],

    "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，设备日志显示独居老人的日常活动模式稳定且符合预期。",
  "reasoning": [
    "1. 活动规律性分析：对比2026-08-19至2026-08-21的跨天摘要数据，各房间的活动计数（如living_room=210, bedroom=242等）保持高度一致，表明住户的生活作息非常规律，无突发的长时间静止（可能暗示跌倒或昏迷）或异常活跃迹象。",
    "2. 关键时间窗行为验证：在早晨7:30-9:30的关键起床/活动时段，日志显示厨房(kitchen)、卧室(bedroom)和入口(entrance)均有正常的占用信号(Occupancy=1)，随后客厅(living_room)也出现占用信号。这符合老人起床后在卫生间、厨房准备早餐，最后进入客厅休息的正常动线。",
    "3. 安全设备状态检查：日志中未出现烟雾报警器(smoke_co_alarm)触发、漏水传感器(water_leak_detector)报警或灶具(cook_surface)长时间开启无人看管的记录。门锁(lock)仅在8月21日早晨有一次手动开锁记录，结合随后的玄关占用信号，判断为正常外出或取物行为，非非法入侵。",
    "4. 传感器数据合理性：温度读数在合理范围内波动（约24-25°C），无剧烈跳变或传感器卡死（stuck）的迹象；占用传感器信号随时间自然变化，无逻辑冲突。"
  ],
  "key_evidence": [
    "连续三天各房间活动计数高度一致 (e.g., living_room始终为210)",
    "早晨时段厨房、卧室、入口均有正常的占用信号序列，符合起床动线",
    "无烟雾、漏水或异常门锁操作警报",
    "温度传感器读数稳定，无异常漂移"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预",
    "建议定期校准温度传感器以确保长期数据准确性"
  ]
}
```

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
{

    "1. 活动模式一致性分析：对比2026-08-15至08-17三天的日志，老人在早晨（约07:30-09:00）起床、使用厨房和客厅的活动时间窗口高度一致。例如，厨房 occupancy 传感器均在07:30-07:45左右首次触发，随后在08:00-09:00期间持续有活动记录，符合老年人晨间洗漱、准备早餐的习惯。",
    "2. 门锁与出入安全：日志中仅在08:23 (Day 1) 和 08:30 (Day 3) 记录了入户门的 Manual Lock 操作，且伴随 entrance_occupancy 传感器的激活，表明是老人正常出门并反锁房门。Day 2 虽无手动上锁记录，但 DoorLock.LockState = 2 (Locked) 且 contact_sensor 为 False (Closed)，结合无异常入侵报警，视为正常状态维持。未发现非授权时段的开锁或闯入迹象。",
    "3. 健康与安全指标正常：所有温度传感器读数在合理范围内（24°C-25°C左右），无极端高温提示火灾风险。烟雾报警器（smoke_co_alarm）在整个日志片段中未触发任何警报事件。厨房灶具（cook_surface）虽有 occupancy 关联，但未出现长时间无人看管导致的超时未关闭报警（通常需结合灶具状态位，此处仅体现有人活动，且后续有离开记录）。",
    "4. 传感器状态正常：Occupancy 传感器在人员离开后（如08:00 living_room 变为 0）能正确归零，并在人员返回后再次激活，无传感器卡死（stuck）或漂移（drift）迹象。Bathroom 传感器短暂触发后归零，符合如厕习惯。"

## 任务
以下是过去 2 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": 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: 正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "key_evidence": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

{
  "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": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
