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。

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
{

  "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",

  ],

}
```

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。

    "推理步骤 1: 凌晨 02:11 至 02:30 期间，门锁解锁、门接触传感器触发（False 表示开门）、玄关灯开启，随后客厅运动传感器在 02:13 检测到有人，符合住户夜间起床如厕或短暂活动的正常逻辑。",
    "推理步骤 2: 该时段内所有房间（包括卧室和卫生间）的运动传感器均报告无人（Occupancy = 0），且活动结束于 02:30，表明住户已重新离开并锁好门（虽然日志未显式记录再次上锁事件，但结合后续长时间无活动推断为正常状态）。",
    "推理步骤 3: 早晨 07:39 的日志显示手动操作门锁并处于锁定状态（LockState=2），这是典型的住户出门上班或外出的标准流程，时间规律且设备响应正常。"

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",

  ],
  "recommended_actions": [

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。

    "交叉验证失败：尽管日志中显示客厅有人活动 (Occupancy = 1) 时温度读数最高，但考虑到人体产热无法使室温瞬间升高至 2400°C，且同一时间段内相邻房间温度正常，排除了真实火灾或极端天气导致全屋升温的可能性，确认为单一设备的数据漂移或校准错误。"

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",

  ],
  "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。

    "推理步骤 1: 分析时间窗口与活动状态。日志显示在 2026-08-08T01:30:00 至 02:30:00 期间，所有房间（包括客厅、卧室、厨房、卫生间和玄关）的运动传感器均报告 Occupancy = 0，持续长达 1 小时无人活动。对于独居老人而言，整夜完全无活动属于显著异常模式。",
    "推理步骤 2: 结合环境数据交叉验证。在同一时间段内，客厅、卧室和厨房的温度传感器读数持续上升（从约 23.1°C 升至 23.7°C），且数值呈现单调递增趋势而非自然波动。这表明虽然无人移动，但可能有热源（如电器未关、窗户未关导致热积聚或设备故障）正在运行，或者老人处于静止不动的虚弱/昏迷状态无法产生体感温度变化以外的信号。",
    "推理步骤 3: 评估后续行为逻辑。直到 T02:11:00 门锁被操作并开门，随后 T02:13:00 客厅才检测到有人进入。这一延迟（从全室无人到开门进屋）暗示老人可能是在屋内某处被发现或自行苏醒后离开，中间的 1 小时空白期构成了严重的“失联”风险窗口。考虑到住户为独居老人，这种长时间的静默伴随环境温度异常是典型的潜在跌倒、突发疾病或被困风险特征。"

    "从最后检测到全员离房 (T02:30) 到首次检测到有人进入 (T02:13 - 此处时间线需修正：实际是 T02:11 开门，T02:13 检测到人，说明开门即有人，之前的无人状态可能是老人已不在原位或处于静止状态)，存在明显的活动断档。",

    "若无法联系，建议启动社区应急响应机制或安排人员上门查看。",
    "检查家中空调、取暖器及厨房电器是否因误操作导致过热或故障，排除火灾隐患。",

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
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

请按以下 JSON 格式回答：

```json

  "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",

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",

    "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。

  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示在 2026-08-02 凌晨 02:31 分，living_room_window_contact 状态变为 False（窗户打开）。此时为深夜，独居老人通常已入睡，且后续日志显示 living_room_occupancy 在 02:34 之前一直为 0，表明屋内无人。",
    "推理步骤 2: 温度异常趋势分析。从 02:31 窗户打开开始，客厅温度传感器读数呈现明显的上升趋势：从 02:35 的 23.48°C (2348mK) 一路攀升，到 04:00 达到 23.97°C (2397mK)，并在 04:05 达到峰值 24.13°C (2413mK)。这种在无人员活动的情况下，夜间室温显著高于正常睡眠环境（通常应低于 22°C）且持续上升的模式非常可疑。",
    "推理步骤 3: 排除正常行为与综合判断。虽然夏季夜晚开窗可能导致热量进入，但考虑到是独居老人，且温度在短时间内（约 1.5 小时）上升了接近 1°C 并维持在高位，结合窗户在凌晨非正常开启的时间点，最合理的解释是发生了外部火源引燃（如窗外杂物起火、线路短路等），导致热空气涌入或烟雾/热气积聚，或者窗户被非法入侵者打开以进行破坏/盗窃前的试探。对于独居老人而言，这是最高级别的安全威胁。"

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",

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。
