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": [

}
```

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。

    "传感器数据可信：所有温度传感器数值均在合理范围内（约 24°C - 26°C，对应日志中的 2400-2600 毫开尔文），且数值随时间有自然的波动趋势，未见传感器卡死、漂移或故障导致的异常跳变。"

## 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",

  ],
  "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。

  "threat_description": "设备日志显示独居老人的日常活动模式正常，无入侵、火灾或设备故障迹象。",

    "推理步骤 1: 温度数据分析。日志中的温度值（如 living_room_temp_sensor 的 2547）明显是乘以 10 后的毫摄氏度单位（即 25.47°C），数值在合理的生活环境范围内（22-26°C），且随时间有自然的波动和下降趋势，未出现传感器卡死（stuck）或漂移（drift）导致的异常恒定值或极端值。",
    "推理步骤 2: 行为模式分析。厨房灶具（cook_surface）在有人时开启，随后关闭；厨房灯（kitchen_light）在早晨和傍晚等常规时间段开启。所有运动传感器（occupancy_sensor）的触发时间与房间内的其他活动（如温度变化、灯光开关）逻辑一致，符合独居老人正常的起居规律（起床、做饭、休息）。",
    "推理步骤 3: 安全设备状态。烟雾报警器（smoke_co_alarm）和漏水传感器（water_leak_detector）在提供的日志片段中未报告任何报警事件（Alarm 属性未置位），且相关区域（厨房、卫生间）的温度和占用情况正常，排除了火灾隐患和漏水风险。"

    "无任何安全设备（烟雾、漏水）触发报警信号。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需立即干预。",
    "建议定期校准温度传感器以确保读数精度（虽然目前数据看似正常，但作为预防性维护）。"

System:
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: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:20，此时独居老人通常处于睡眠状态（非活动时间）。在此期间，所有房间（包括客厅、卧室、卫生间、玄关）的运动传感器均报告 Occupancy = 0，确认屋内无人。",
    "推理步骤 2: 设备状态与行为分析。尽管厨房无人（kitchen_occupancy 在大部分时间为 0），但厨房温度传感器读数从 02:10 的 23.26°C (2326) 开始持续攀升，至 04:10 达到 24.14°C (2414)，温差超过 9 度。更关键的是，在 02:50 出现了 kitchen_light 开启的事件，随后温度继续飙升。",
    "推理步骤 3: 异常模式识别。对于独居老人家庭，凌晨时段厨房灯光自动开启且伴随无人的高温环境，极大概率是灶具（cook_surface）被意外开启或故障导致加热。考虑到 Matter 协议中温度值通常为整数乘以 10（即 2414 代表 241.4°C 或 24.14°C，结合室温背景，此处数值明显高于正常室温，若按摄氏度理解则已接近危险阈值；即便按毫摄氏度理解，短时间内上升 9 度也远超自然散热速率），这种“无人 + 开灯/热源 + 快速升温”的组合是典型的未受监控烹饪或电器故障导致的火灾前兆。",
    "推理步骤 4: 风险评估。厨房烟雾报警器虽然存在，但在温度急剧上升阶段未见报警记录（可能是尚未触发阈值或日志截断），但这不能排除风险。对于独居老人，夜间厨房起火后果极其严重，必须视为最高优先级威胁。"
  ],
  "key_evidence": [
    "02:10 - 04:20 期间，全屋运动传感器均为 0（无人），但厨房温度从 ~23.26°C 持续上升至 ~24.14°C。",
    "02:50:00 发生 kitchen_light 开启事件，紧接着温度继续异常爬升，表明有热源在工作。",
    "温度变化速率过快（约 2 小时升温近 10 度），不符合自然环境温度波动规律，符合加热设备运行特征。"
  ],
  "recommended_actions": [
    "立即远程通知住户或其紧急联系人，告知可能存在厨房火险。",
    "检查并重置厨房烟雾报警器，确保其处于正常工作状态。",
    "建议系统在未来类似场景下（深夜无人时检测到厨房温度异常升高）自动切断厨房电源或联动声光警报。",

System:
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

  "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

## 任务
请从下面 2 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。

}

Rejected response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式正常，设备运行状态符合预期，未发现安全威胁或异常行为。",
  "reasoning": [
    "时间序列分析：厨房灶具 (kitchen_cook_surface) 的开启与关闭事件（如 12:00-12:05, 16:52, 10:54-11:00, 12:00-12:04）均伴随厨房运动传感器 (kitchen_occupancy) 的活跃信号，且持续时间短（通常<5分钟），符合老人短时间烹饪或检查的习惯，无长时间无人看管烹饪迹象。",
    "环境数据合理性：温度传感器读数（如 living_room_temp_sensor 的 2535-2548 mK，即约 25.3-25.5°C）处于舒适且正常的室温范围，数值波动平稳，无传感器漂移、卡死或突变现象；卧室温度略低也符合夜间/休息时段特征。",
    " occupancy 逻辑一致：各房间的运动传感器状态变化与光照、窗帘等执行器动作逻辑自洽（例如 12:29 关灯并拉上卧室窗帘，随后卧室占用检测持续存在直至下午，符合老人午休场景），未见入侵者闯入导致的异常跨房间快速移动或门锁异常开启记录。"
  ],
  "key_evidence": [
    "厨房灶具操作均有对应的现场人员活动记录，且单次操作时间短，未出现‘灶具开启后长时间无人’的 unattended_cooking 模式。",
    "所有温度传感器读数稳定在合理区间（~25°C），无 sensor_drift 或 sensor_malfunction 特征。",
    "卧室窗帘关闭与灯光熄灭的时间点吻合，且后续有持续的占用检测，表明是住户自主行为而非外部干扰。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期复核 Matter 协议下传感器校准状态，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
{
  "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。

Rejected response:

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "过去三天的设备日志显示独居老人的活动模式高度规律且符合正常生活作息，未发现安全威胁或异常行为。",
  "reasoning": [
    "时间模式分析：住户每天在早上 07:25-08:00 左右起床（卧室有人），随后前往客厅和厨房活动，晚上约 23:41 后客厅无人，次日清晨再次出现，这种昼夜节律非常稳定，符合独居老人的正常生活习惯。",
    "空间逻辑验证：当检测到入户门开启（entrance_occupancy=1）时，紧接着会有厨房、客厅等公共区域的活动记录，且从未出现‘门开但屋内无其他活动’的长时间滞留情况，排除了入侵者潜入的可能性。",
    "环境数据合理性：温度传感器读数（如 living_room_temp_sensor 的 2534-2556 mK，即 25.3-25.6°C）处于舒适且合理的室温范围，未出现极端高温或低温导致的设备故障或火灾风险迹象；漏水传感器也未触发报警。",
    "设备状态一致性：所有运动传感器和接触传感器的状态变化相互印证（例如开门后进入室内，门锁状态虽未直接上报但通过 occupancy 变化可推断正常进出），没有发现传感器卡死或漂移的迹象。"
  ],
  "key_evidence": [
    "连续三天（8/12-8/14）的起床时间和夜间离开时间保持高度一致（误差<10 分钟）。",

    "入户门开启事件均伴随正常的室内活动序列，无异常停留或反向移动（从内向外突然消失）的情况。"
  ],
  "recommended_actions": [
    "继续保持当前的监控频率，无需额外干预。",
    "建议定期检查老人身体健康状况，确保其日常活动能力稳定。",
    "确认智能家居系统固件为最新状态，以维持 Matter 协议下的设备稳定性。"
