## 任务
以下是过去一段时间的设备活动记录。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，日志显示为独居老人在上午时段的正常居家活动及环境监控数据。",
  "reasoning": [
    "1. 人员活动模式分析：日志显示从08:40开始，客厅、厨房、卧室、玄关等区域陆续出现 occupancy=1（有人）的状态，且持续至10:35。这种多房间、长时段的人员存在符合独居老人在上午进行日常起居（如起床、洗漱、准备早餐或休息）的行为特征，不存在长时间无人的异常静默（排除 health_concern/abnormal_inactivity）。",
    "2. 门窗状态分析：重点关注的 living_room_window_contact 和 bedroom_window_contact 在 10:05-10:06 记录为 False（关闭）。结合此时段室内温度稳定（约25°C左右），且无烟雾或燃气报警触发，窗户关闭属于正常的节能或防风行为，并非入侵迹象。",
    "3. 设备状态与传感器数据：温度传感器读数在合理范围内波动（24-25°C），无剧烈跳变，表明传感器工作正常（排除 sensor_malfunction/sensor_drift）。灯光在有人时开启（08:40, 10:07），符合自动化逻辑或用户习惯。无门锁异常开启记录，无漏水或烟雾报警。",
    "4. 综合判断：所有事件均指向正常的家庭日常生活场景，没有发现入侵、火灾、健康危机或设备故障的迹象。"
  ],
  "key_evidence": [
    "08:40 - 10:35 期间多个房间（living_room, kitchen, bedroom, entrance）持续检测到 Occupancy = 1，符合老人日间活动规律。",
    "10:05 - 10:06 living_room_window_contact 和 bedroom_window_contact 均为 False（关闭状态），且无伴随的入侵警报。",
    "温度传感器数值稳定在 2400-2550 (24-25.5°C) 之间，无异常突变。",
    "无任何 smoke_co_alarm, water_leak_detector 或 door_lock 异常事件触发。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续维持当前的监控策略，确保老人日常活动轨迹保持在预期范围内即可。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "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": [
    "白天集中通风可能连续开窗，但通常伴随正常居家活动；异常样本发生在夜间。"
  ],
  "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",

    "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

    "2.  温度传感器读数（如2456代表24.56°C）随时间缓慢上升，从清晨的约24.5°C升至午后的25.3°C左右，且各房间温差合理，无剧烈波动或传感器卡死/漂移的迹象。",
    "3.  关键设备操作逻辑一致：例如8月28日早晨，厨房灯亮起（07:01）与玄关门锁手动解锁（07:16）及入户门关闭（07:16）的时间序列连贯，表明是住户正常出门流程，而非入侵或非法开锁。",
    "4.  跨天活动摘要显示，8月29日living_room的活动计数显著下降（49 vs 前两天的114+），结合日志中该日仅有一次短暂的occupancy触发和灯光开启，可能意味着该日住户外出时间更长或行程不同，但这属于行为模式的正常波动，不构成安全威胁。"

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",

```

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": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，日志显示为正常的家庭日常活动及传感器数据波动。",
  "reasoning": [
    "1. **人员活动模式分析**：三天内的 occupancy（占用）传感器数据显示了规律性的作息。早晨6:00-7:30期间，主卧、儿童房、客厅等区域陆续出现占用信号，符合家庭成员起床活动的正常时间窗口。晚上至凌晨时段（如2026-07-11 01:00），主要生活区无占用，符合夜间休息状态。没有发现深夜非法入侵或长时间无人却有人活动的矛盾情况。",
    "2. **门锁与入口安全**：入户门传感器和门锁仅在早晨特定时间（如07:16, 07:10）有操作记录，且伴随玄关/入口运动传感器的激活，表明是住户正常出门或回家。没有发现非授权时间的开锁尝试或门锁故障迹象。",
    "3. **设备与环境数据**：温度传感器读数在合理范围内（约24-25摄氏度，Matter协议中通常单位为0.01度Celsius，即24.53°C左右），数值随时间缓慢变化，符合室内热惯性特征，无突变或传感器卡死（stuck）现象。厨房灯在傍晚开启（18:31, 06:42次日），属于正常照明行为。",
    "4. **关键设备状态**：重点关注的 kitchen_light 和 living_room_occupancy 均表现正常。厨房灯开启时未见烟雾报警器触发，排除火灾风险；客厅占用传感器与灯光/空调等设备联动逻辑未发现冲突。"

    "2026-07-09T07:16:26: 前门锁状态变更并伴随手动操作事件，随后入口占用传感器激活，确认为正常离家/归家行为。",
    "TemperatureMeasurement.MeasuredValue 在 2445-2544 之间波动，变化趋势平滑，无异常跳变。",

    "推理步骤 2: 观察非缺失数据的趋势，厨房温度在 07:00 左右从 2493 骤降至 2484，随后又回升至 2513，这种在无空调干预情况下的剧烈且无规律的跳变（结合数据丢失），不符合正常热力学规律，排除了单纯的环境温度自然波动，指向传感器读数不可信（Sensor Drift/Malfunction）。",
    "推理步骤 3: 结合家庭布局，厨房是火灾风险最高区域（有灶具 cook_surface）。如果温度传感器失效，系统将无法触发基于高温的自动切断电源或报警机制，构成了潜在的安全隐患（unattended_cooking risk due to sensor failure），因此判定为高置信度的传感器故障。"

## 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",

    "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，所有设备状态变化符合正常家庭作息规律。",

    "2. 关键设备状态验证：重点关注的厨房灶具（kitchen_cook_surface）仅在7月24日06:39短暂开启，随后无持续高温或烟雾报警记录，且该时间段有人类活动迹象（运动传感器），排除无人看管烹饪风险。入户门锁在7月24日07:37锁定，与出门时间吻合，无非法入侵迹象。",
    "3. 传感器数据合理性：温度传感器读数（如2447代表24.47°C）随时间缓慢变化，符合室内热惯性特征，无突变或停滞现象，排除传感器故障。客厅 occupancy 在白天大部分时间为0，表明家中无人或人员主要在非客厅区域活动，这与周末或居家办公/休息的常见模式一致，并非异常静默。"
  ],
  "key_evidence": [

## 任务
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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: ...",

    "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": "检测到阳台门开启、灯光自动亮起及洗衣机启动，结合玄关人员活动迹象，判断为住户正常进行洗衣活动的行为模式。",
  "reasoning": [
    "1. 分析核心事件链：在 17:20:00，阳台门传感器显示关闭（False，即门被打开），紧接着阳台灯开启（True），随后洗衣机开始运行（OperationalState = 1）。这一序列符合典型的‘开门->进屋/操作->设备启动’的逻辑顺序。",
    "2. 关联环境上下文：日志中多次出现 entrance_occupancy (玄关运动传感器) 的状态变化（16:46, 17:06, 17:26, 17:46 均为 Occupancy=1），表明此时段屋内有人活动。虽然其他房间（客厅、卧室）的 occupancy 传感器显示为 0，但这可能是因为传感器灵敏度、安装角度或用户处于非检测区域，而玄关和阳台作为主要活动路径被捕捉到。",
    "3. 排除异常风险：阳台门在傍晚时分开启用于晾晒或取放衣物是常见行为；洗衣机在有人活动的时段启动属于正常使用；没有发现门锁异常、烟雾报警或漏水等危险信号。因此，该事件序列属于正常的家庭日常活动。"
  ],
  "key_evidence": [
    "17:20:00 balcony_door_contact 状态变为 False (门开)",
    "17:20:00 balcony_light 状态变为 True (灯亮)",
    "17:21:00 balcony_laundry_washer 状态变为 1 (洗衣机运行)",
    "17:06-17:46 期间 entrance_occupancy 多次触发，证明有人在室内活动"
  ],
  "recommended_actions": [
    "无需采取安全措施，系统记录正常。",
    "建议确认阳台门开启后是否及时关闭，以维持室内温湿度稳定（可选优化）。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "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": [
    "正常样本是傍晚去阳台洗衣，伴随洗衣机启动；异常样本发生在深夜且后续转入室内活动。"
  ],
  "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",
  "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。

    "1.  occupancy传感器（运动检测）在凌晨至清晨时段（05:00-07:00）主要显示为0（无人），仅在特定时间点短暂触发为1，随后恢复为0或保持关闭状态，符合住户起床、短暂活动后离开客厅的正常行为逻辑。",
    "2.  温度传感器数据变化平缓且数值合理（约24-25摄氏度，即2400-2500单位），无剧烈跳变或异常高温/低温，表明环境稳定，无火灾或极端天气导致的设备故障迹象。",
    "3.  8月10日06:41客厅有人，06:42厨房灯开启，这是典型的早晨起床后前往厨房准备早餐或饮水的行为序列，时间间隔极短（1分钟），符合人类反应速度和生活习惯。",
    "4.  跨天摘要中，8月10日entrance和master_bedroom活动量激增（230和228次），结合当日早晨的活跃记录，可能暗示住户在该日有特殊的作息安排或访客活动，但仅凭当前片段无法确认为入侵，且无门锁异常打开或非法闯入的证据。"

  "threat_description": "客厅温度传感器读数严重偏离物理现实，显示异常高温（2400K+），且与住户活动模式不匹配。",
  "reasoning": [
    "推理步骤 1: 分析温度数据发现，从 2026-08-08T05:00:00 开始，living_room_temp_sensor 的 MeasuredValue 持续在 2437 到 2541 之间波动。考虑到 Matter 协议中温度通常以 0.1°C 或 1°C 为单位，这些数值（如 2444）极大概率代表 24.44°C 或 244.4°C。若为 244°C，室内早已起火；若为 24.4°C，则数值本身无意义（应为 2440 表示 24.40 或其他单位错误）。对比同时间段其他房间（master_bedroom, kitchen）的温度读数（2459-2527），虽然也存在类似量级问题，但厨房和主卧有明确的空调/灶具活动记录作为上下文，而客厅在大部分高读数期间无人（Occupancy=0）。",
    "推理步骤 2: 检查 occupancy 状态与温度的相关性。在 2026-08-08T06:35:00 至 08:00:00 期间，living_room_occupancy 曾短暂变为 1，随后又变回 0。然而，当 occupancy 为 0 时，温度读数依然维持在 2500+ 的异常高位。正常的室温传感器在无人且无热源的情况下，不应出现如此剧烈且持续的‘高温’漂移，尤其是在夜间/清晨时段（05:00-08:00）。",
    "推理步骤 3: 排除设备故障导致的误报。虽然可能是传感器硬件故障，但结合跨天数据（08-09, 08-10），该传感器在每天清晨都表现出相同的异常上升趋势，且数值范围固定在一个非物理合理的区间（2400-2540），这符合典型的传感器校准失效、固件 Bug 或通信数据包解析错误（Sensor Drift/Malfunction），而非真实的环境变化。这种系统性的数据异常可能导致基于此数据的自动化逻辑（如空调控制、火灾报警）做出错误决策。"

    "同一时间段内，其他房间（如 master_bedroom, kitchen）的温度读数也呈现类似的异常量级（2400+），表明可能存在全局性的传感器配置错误或数据上报格式问题，但客厅作为重点监控区域，其异常最为显著且缺乏对应的热源活动日志支持。"

  "recommended_actions": [
    "立即检查客厅温度传感器的硬件连接及供电情况，确认是否发生物理损坏。",
    "审查 Matter 设备配置，确认温度传感器的单位设置（摄氏度 vs 开尔文 vs 毫摄氏度）是否正确，是否存在固件版本缺陷导致数据上报错误。",
