## 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",

## 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: ..."
  ],
  "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。

  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器读数严重异常（高达 2700+），远超物理可能范围，且与其他房间正常读数形成巨大反差，表明传感器故障或数据上报错误。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，从 18:05 开始，厨房温度传感器 (kitchen_temp_sensor) 的读数急剧上升并持续高位运行（2455 -> 2510 -> ... -> 2713），而同一时间段内客厅、主卧、次卧的温度均在 2300-2350 之间波动，符合夏季室温常态。",
    "推理步骤 2: 检查关联设备状态，虽然日志中显示入户门锁被手动上锁 (LockOperationType=1)，随后玄关灯和客厅空调开启，但并未触发任何烟雾报警器 (smoke_co_alarm) 事件，也未检测到厨房窗户打开或灶具 (cook_surface) 的异常操作记录。如果发生真实火灾或高温烹饪事故，通常会有其他传感器联动报警。",
    "推理步骤 3: 结合 Matter 协议标准，温度测量值通常在 -40 到 +125 摄氏度之间（即 4000-12500 毫开尔文）。当前读数 2700 对应约 -1.6 摄氏度，但在夏季室内环境下出现此数值极不合理；若视为绝对温度则完全不可能。这种‘高得离谱’且持续稳定的数值特征，是典型的传感器漂移、校准失败或固件 Bug 导致的 Sensor Malfunction，而非真实的物理环境变化。"

    "尽管厨房温度显示极高，但同时间段的 smoke_co_alarm 未触发报警，且无相关窗户开启或人员进入厨房的操作日志。",
    "温度数值逻辑矛盾：2700 的读数在夏季室内环境中既不符合高温（应为 >3000）也不符合低温，属于无效数据。"
  ],
  "recommended_actions": [
    "立即标记厨房温度传感器为‘故障/需维护’状态，并在用户端推送通知提醒更换电池或联系技术支持。",
    "暂时忽略该传感器的温度数据用于自动化场景（如自动开窗或启动空调），防止误触发其他联动设备。",
    "建议用户在下次回家时手动检查厨房实际温度及传感器外观，确认是否有硬件损坏。"

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: ..."
  ],
  "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": "设备使用频率突然翻倍",
  "reasoning": [
    "推理步骤1: 同一设备短时间高频重复使用",
    "推理步骤2: 频率显著高于普通居家行为",
    "推理步骤3: 更像异常强迫式操作"
  ],
  "key_evidence": [
    "同一设备短时间高频重复使用",

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房灶具在无人看管的情况下长时间开启，且伴随温度传感器读数异常飙升及数据丢失，存在极高的火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，用户在 19:14:30 开启了厨房灶具 (kitchen_cook_surface)，但在 19:29:00 才关闭。在此期间（约 15 分钟），系统检测到多次人员进入客厅和玄关的活动（entrance_occupancy=1, living_room_occupancy=1），但日志中未出现任何人在厨房区域活动的明确记录（如厨房灯或运动传感器触发），暗示用户可能离开厨房去其他房间，导致灶具处于无人看管状态。",
    "推理步骤 2: 关键证据在于厨房温度传感器的数据表现。从 19:00 到 19:10，厨房温度读数呈指数级异常增长（2350 -> 2426 -> 2495 -> 2556 -> 2621 -> 2682）。虽然数值本身可能是编码格式问题（如摄氏度*10），但其变化速率远超正常烹饪升温速度，且数值极高，符合设备过热或即将起火的特征。",
    "推理步骤 3: 最致命的异常发生在 19:15:00，当厨房温度达到峰值附近时，该传感器报告了 `None`（数据丢失/通信中断）。结合随后温度读数继续跳变至 2682，这表明传感器可能因高温损坏、电路熔断或受到强电磁干扰而失效。在火灾风险场景下，安全传感器（烟雾报警器）的数据丢失是极度危险的信号，意味着家庭失去了对火情的感知能力。"
  ],
  "key_evidence": [
    "19:14:30 开启灶具后，19:29:00 关闭，期间无厨房活动记录，存在无人看管风险。",
    "厨房温度传感器读数在短时间内从 2350 飙升至 2682，且于 19:15:00 出现 `None` 数据丢失，表明传感器可能已因高温故障或通讯中断。",
    "在温度异常升高期间，厨房窗户接触传感器于 19:29:30 变为 False（打开），若此时有明火，热空气上升可能导致窗户被吹开或人为开窗通风，加剧火势蔓延风险。"
  ],
  "recommended_actions": [
    "立即前往厨房检查是否有明火、烟雾或焦糊味。",
    "检查厨房温度传感器是否物理损坏，并尝试重启或更换传感器以恢复监控。",
    "确认厨房烟雾报警器功能是否正常，必要时手动测试。",
    "建议在未来配置自动化规则：当检测到灶具开启超过设定阈值（如 10 分钟）且未检测到厨房有人时，自动切断电源或发送紧急警报。"

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",

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。

    "后续活动佐证：门开后不久（18:47），厨房设备开始运作，说明屋内生活如常，进一步确认了“人在屋内”的状态，排除了住户正常出门买菜等场景。"

## 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",

    "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。

    "数据合理性分析：日志中 `living_room_temp_sensor` 和 `kitchen_temp_sensor` 报告的 `MeasuredValue` 数值高达 2498、2544 等。考虑到 Matter 协议通常使用毫开尔文 (mK) 作为单位，这些数值换算后约为 2.5°C 至 2.5°C（若单位为 mK 则对应约 2.5°C，但这对于夏季白天且有人活动的房间来说过低；若设备配置错误直接上报了原始 ADC 值或其他未转换的整数，则完全无意义）。更可能的情况是，传感器发生了严重的读数漂移或固件 bug，输出了非物理意义的巨大数值（例如本应是 25°C 却报成了 2500+）。",
    "行为模式矛盾：尽管日志显示住户在客厅 (`living_room_occupancy`) 和厨房 (`kitchen_occupancy`) 有频繁的活动记录（如做饭、走动），但温度传感器并未反映正常的室温变化趋势（通常随人体活动略有上升或随空调调节而变化），而是持续输出异常的高位数值。这种‘有人活动’与‘温度数据异常’的不匹配是典型的传感器故障特征。",
    "风险评估：对于独居老人家庭，准确的温度监测至关重要。如果该传感器用于联动空调或烟雾报警器的逻辑判断，其故障可能导致在真实高温或火灾初期无法触发警报，或者错误地触发警报造成恐慌。鉴于涉及独居老人，任何感知设备的失效都属于高风险事件。"

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": true,
  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "设备使用频率突然翻倍",
  "reasoning": [
    "推理步骤1: 同一设备短时间高频重复使用",
    "推理步骤2: 频率显著高于普通居家行为",
    "推理步骤3: 更像异常强迫式操作"
  ],
  "key_evidence": [
    "同一设备短时间高频重复使用",
    "频率显著高于普通居家行为",
    "更像异常强迫式操作"
  ],
  "recommended_actions": [
    "标记为异常设备交互模式，建议持续观察。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的家庭晚间活动模式，包括人员进出、烹饪准备及空调调节，未发现安全威胁或设备故障。",
  "reasoning": [
    "时间线分析：事件发生在傍晚至晚上（17:20 - 19:25），符合典型的下班回家、做饭和休息的时间段。",
    "行为逻辑验证：入户门传感器（entrance_occupancy）多次检测到有人进入，随后客厅灯（living_room_light_1）和空调（living_room_ac）被开启，且温度设定为制冷模式（SystemMode=3），这与住户回家感到炎热并开启设备的习惯完全一致。",
    "厨房活动合理性：在 18:31 开启灶具（cook_surface），并在约 20 分钟后关闭，期间厨房窗户短暂打开（18:51），这是非常自然的通风和烹饪行为，无异常停留或危险迹象。",
    "设备状态正常：所有传感器读数（温度、占用状态）变化平滑且符合物理规律，未见数据丢失、卡死或逻辑冲突（如无人时灯常亮、门窗未关却有人活动等）。",
    "跨房间联动正常：主卧和次卧的占用状态与温度变化反映了家庭成员在不同房间的合理移动，整体环境处于受控状态。"
  ],
  "key_evidence": [
    "18:13 和 18:33 等时间点 entrance_occupancy 变为 1，紧接着 living_room_light_1 和 living_room_ac 被激活，表明是住户主动回家操作。",
    "18:31-18:51 期间的 kitchen_cook_surface On/Off 序列以及随后的 kitchen_window_contact False 变化，构成了完整的‘开火 - 烹饪 - 通风’闭环。",
    "全时段温度传感器数据连续且数值合理（约 22-23°C），无任何突变或无效值（除一次短暂的 None 外，不影响整体判断）。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统运行正常。",
    "建议继续保持对关键区域（如厨房烟雾报警器、漏水传感器）的定期维护检查。"
