## 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",

    "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": "连续多天不使用厨房",
  "reasoning": [
    "推理步骤1: 多天都有居家活动",
    "推理步骤2: 却始终没有厨房使用线索",

  ],

  ]
}

```json
{
  "is_anomaly": false,
  "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稳定、规律，未发现入侵、异常行为或设备故障迹象。",
  "reasoning": [
    "入住与离开时间高度一致：每天早晨约 07:10-07:20 玄关传感器检测到进入，随后厨房和客厅温度上升（表明开始烹饪/开启空调），晚上约 15:25 后客厅再次有人但无后续夜间活动记录，符合独居老人白天外出或居家休息的常规作息。",
    "多房间 occupancy 状态逻辑自洽：当卧室 occupancy 为 1 时，卧室温度传感器持续报告数据；当客厅 occupancy 变为 1 时，客厅温度随之变化且灯光开启，不存在‘人在某处但传感器未响应’或‘无人却频繁触发’的矛盾现象。",
    "关键安全设备工作正常：入户门锁在 08:26 被锁定（LockState=2），窗户接触传感器、烟雾报警器等未出现异常跳变或长时间离线，漏水传感器也未触发警报，排除了 sensor_malfunction 或 safety_device_failure 的可能性。"
  ],
  "key_evidence": [
    "每日固定时段（~07:15）entrance_occupancy 从 0 变为 1，紧接着 kitchen_temp_sensor 数值上升，表明正常的起床和早餐准备流程。",
    "living_room_light 在 08:26:13 被打开，此时 living_room_occupancy 也为 1，动作与状态同步，无延迟或冲突。",
    "连续三天 bedroom_occupancy 和 living_room_occupancy 的变化曲线平滑，无突然的长时间空置后瞬间多人进入等可疑模式。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期（如每周）人工核对一次门锁电池电量及烟雾报警器功能，作为预防性维护。"
  ]

## 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": [

    "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": "behavioral_anomaly",

    "门锁状态正常：入户门传感器 (front_door_contact) 在 18:20 变为 False（开门），随后在 18:21 客厅灯开启，这符合住户回家并进入室内的标准行为序列，且后续未检测到非法闯入迹象。",
    "温度数据合理性：虽然温度值以毫开尔文 (mK) 为单位（例如 2386 mK ≈ 23.86°C），数值波动范围在 22.8°C 至 23.9°C 之间，属于夏季室内空调调节下的正常环境温度波动，未见极端高温或低温导致的设备故障或火灾风险。",
    "设备联动逻辑正常：当有人进入（18:22 主卧检测到 occupancy=1）时，系统响应合理；当无人时（如 17:30, 18:00 等多次报告），所有房间 occupancy 均为 0，且无异常设备误报。",
    "无关键安全事件：未检测到烟雾报警、漏水报警、一氧化碳泄漏或门窗异常开启（除预期的回家开门外）等紧急事件。"
  ],
  "key_evidence": [

  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期检查温度传感器的校准情况，确保单位转换正确（当前显示为 mK，需确认前端展示已转换为摄氏度）。"

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
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",

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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "连续多天不使用厨房",
  "reasoning": [

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示住户活动规律正常，设备运行符合预期，未发现安全威胁或异常模式。",
  "reasoning": [
    "温度数据验证：所有温度传感器（living_room, kitchen, bedroom）报告的数值均在 2406-2558 范围内。考虑到 Matter 协议中温度通常以 0.01°C 为单位存储，这些数值对应 24.06°C - 25.58°C，属于夏季室内正常的室温波动范围，排除了传感器故障或漂移（sensor_drift/sensor_malfunction）。",
    " occupancy 行为分析：卧室和客厅的占用状态变化与时间戳高度吻合。例如，早晨 06:30-07:00 期间卧室有人且随后离开，紧接着 07:16 门锁被手动解锁并开门，随后厨房开始有温度读数（暗示烹饪或电器使用），这构成了完整的‘起床 - 出门/准备早餐’逻辑链条，符合正常生活作息。",
    " 设备联动逻辑：日志中未出现违反物理常识的冲突事件。例如，当检测到窗户打开（contact_sensor=False）时，并未伴随烟雾报警或异常高温；门锁操作（LockOperation）前后接触传感器状态变化合理。夜间及清晨无长时间无人但高能耗或异常活动的迹象。"
  ],
  "key_evidence": [
    "温度读数稳定在 24-26°C 区间，无极端高温或低温异常。",
    " 07:16 门锁解锁事件与随后的厨房温度上升、卧室人员离开事件在时间线上形成合理的因果序列。",
    " 跨天活动摘要显示各房间占用次数分布均匀，无异常的长时间静止或频繁闯入迹象。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期校准温度传感器以确保长期精度，尽管目前读数正常。"
  ]

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",

  ],
  "key_evidence": [
    "front_door_lock 在 07:39 和 07:33 记录到合法的 Manual LockOperation 事件，且前后均有 entrance_occupancy 变化支持。",
    "所有 temperature_sensor 读数均在 24.9°C 至 25.5°C 之间，无过热或异常低温漂移。",

  "reasoning": [
    "推理步骤 1: 分析日志发现 second_bedroom_temp_sensor 从 07:20 开始持续上报数值，如 2522, 2534, 2544, 2556 等。这些数值的单位如果是摄氏度 (°C)，则意味着房间温度高达 250 多度，这在家庭环境中是不可能的；如果是毫开尔文 (mK) 或其他单位，通常 Matter 协议中的 TemperatureMeasurement.MeasuredValue 单位为 Kelvin，2500K 约为 2227°C，依然极度异常。",
    "推理步骤 2: 对比同一时间段内其他房间的温度传感器数据：living_room (2478-2556), master_bedroom (2500-2550), kitchen (2506-2548)。虽然所有传感器都报出了类似的“高位”数值（约 2478-2556），但考虑到 Matter 标准中温度通常以 Kelvin 为单位，2478K ≈ 2205°C，这显然不是真实的室温。然而，更合理的解释是系统内部存在一个全局的偏移量错误，或者这些数值实际上是某种编码后的值被直接解析为了整数，导致所有传感器同时出现‘漂移’。",
    "推理步骤 3: 进一步观察 occupancy 状态。在 08:00 到 09:00 期间，second_bedroom_occupancy 多次报告为 0（无人），但温度却持续飙升。如果这是真实的高温，且有人进入该房间（例如 08:15 living_room 有人，可能有人去次卧），会触发烟雾报警或空调联动，但日志中未见相关安全设备动作。这种‘无人但超高温’且‘全房同步异常’的模式，极大概率是传感器固件 bug、校准失败或通信协议解析错误导致的 Sensor Drift（传感器漂移/故障），而非真实的火灾风险。",
    "推理步骤 4: 尽管可能是误报，但如此大规模的温度读数异常会导致智能家居自动化逻辑（如空调开启、烟雾报警阈值判断）完全失效，构成潜在的安全隐患（如无法正确响应真实火灾）。因此判定为 sensor_drift。"
