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。

请按以下 JSON 格式回答：

  "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",

    "2. 验证人员存在性：日志中多次出现 entrance_occupancy (玄关运动传感器) 的状态为 1 (Occupancy=1)，特别是在 16:45, 17:05, 17:25, 17:45。这证实了住户在傍晚时段活跃于家中，且位置靠近入口和公共区域，支持了有人在家操作家电的假设。",
    "3. 排除异常风险：没有检测到入侵迹象（如门锁被非法打开、窗户在非正常时间剧烈震动等）；没有火灾或漏水警报；设备状态变化符合日常家务习惯（傍晚回家/休息时洗衣服）。因此，判定为正常行为。"

## 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": [
    "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，所有设备日志符合正常住户作息规律。",
  "reasoning": [
    "1. **作息规律性分析**：连续三天（8月25-27日）的日志显示高度一致的作息模式。早晨06:00-07:30期间，主卧和客厅传感器依次激活，随后入户门在07:24-07:35之间被手动锁定并离开，符合典型的上班/出门流程。晚间19:22左右客厅 occupancy 再次激活，符合下班回家场景。",
    "2. **门锁与传感器联动正常**：8月25日和26日的早晨，`front_door_lock` 均记录为 Manual Lock (LockState=1)，且紧随其后 `entrance_occupancy` 变为 0 或保持低活动状态，表明住户已离开。没有发现非法解锁、多次失败尝试或门未关即离开的情况。",
    "3. **烹饪行为安全**：8月26日早晨厨房灶具 (`kitchen_cook_surface`) 开启，但未见烟雾报警器触发，且该时间段内无其他危险信号（如长时间无人看管后的持续高温报警），结合后续无异常，视为正常早餐准备。",
    "4. **传感器数据合理性**：温度传感器读数随时间缓慢变化（夜间降温，白天升温），数值范围在24°C-25°C左右，符合室内环境温度特征，无突变或停滞现象，排除传感器故障。"
  ],
  "key_evidence": [
    "连续三天早晨 07:24-07:35 出现一致的手动上锁及离家模式",
    "晚间 19:22 左右客厅 occupancy 激活，符合归家逻辑",
    "温度传感器数据平滑变化，无异常跳变",
    "无烟雾报警、漏水报警或非法入侵迹象"
  ],
  "recommended_actions": [
    "无需采取紧急措施",
    "建议继续保持当前的自动化规则（如离家自动布防）"
  ]
}
```

{
  "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": [
    "触发时间位于清晨起床窗口且有轻微抖动，不是固定的可疑重复模式。"
  ],
  "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。

    "2. 验证人员存在性：在洗衣机启动前后（17:06-17:28），主卧、餐厅、玄关和儿童房的运动传感器均持续报告 Occupancy = 1。这证实了家中有人活动，且时间（17:20）符合下班后或傍晚时段的家庭生活习惯。",
    "3. 排除异常风险：没有检测到入侵迹象（如门锁被非法操作、窗户在非正常时间打开）、火灾风险（无烟雾报警）或漏水风险。阳台门关闭且灯亮，说明是住户主动操作而非意外或故障。"

## 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",
  "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": "未检测到安全威胁或异常模式，所有设备日志符合正常的家庭作息规律。",
  "reasoning": [
    "1. **作息规律性分析**：连续三天（7月22-24日）的日志显示高度一致的作息模式。早晨06:35-06:48左右客厅 occupancy 传感器触发，随后卫生间灯光/人员活动，表明住户正常起床。早晨07:13-07:36期间，入户门锁状态变化（解锁->关闭->手动上锁）及玄关 occupancy 触发，符合住户出门上班或外出的典型行为。",
    "2. **环境数据合理性**：温度传感器读数在凌晨至清晨时段呈现缓慢上升趋势（例如从2443mK升至2500mK以上），这符合夜间室内热量积聚或空调关闭后室温回升的物理规律，且各房间温差合理，无突变或传感器故障迹象。",
    "3. **设备联动逻辑正常**：厨房灯在晚间19:02开启（晚餐时间）和早晨06:42-06:54开启（早餐/准备时间），与 occupancy 传感器的活动窗口吻合。没有发现无人时的长明灯、深夜无故报警或门锁被暴力破解等异常事件。"
  ],
  "key_evidence": [
    "连续三天早晨06:35-06:48 living_room_occupancy 变为 1，随后伴随 bathroom_light 开启，符合正常起床流程。",
    "早晨07:13-07:36 front_door_lock 经历 Unlock -> Close -> Lock 操作，且 entrance_occupancy 有相应活动，符合正常离家行为。",
    "温度传感器数值随时间平稳变化，无跳变或停滞，排除 sensor_stuck 或 sensor_malfunction。"
  ],
  "recommended_actions": [
    "无需采取任何安全措施，系统运行正常。",
    "建议继续保持当前的自动化规则设置。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",

  "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。"
  ],

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。

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
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: ..."
  ],
  "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的家庭日常活动（洗衣、烹饪）及传感器数据波动。",
  "reasoning": [
    "1. 阳台区域活动分析：17:20 阳台门传感器状态变为 False（通常表示关闭或锁定），同时阳台灯开启 (True)，紧接着洗衣机启动 (OperationalState=1)。这一序列符合用户回家/在阳台进行家务活动的正常逻辑，无非法入侵迹象。",
    "2. 厨房区域活动分析：17:59 厨房灯开启，17:59:30 灶具开启。这是典型的晚餐准备行为。虽然灶具开启后温度传感器读数出现 None 和数值下降，但这更可能是由于传感器故障、数据上报延迟或环境散热导致的正常物理现象，而非火灾前兆（未见烟雾报警器触发）。",
    "3.  occupancy 与温度数据分析：客厅运动传感器频繁触发 (Occupancy=1) 且伴随温度缓慢下降，符合有人在家且空调运行或门窗微开的场景。卧室传感器持续显示无人 (Occupancy=0)，符合傍晚时段家庭成员集中在公共区域的常态。",
    "4. 排除异常模式：没有发现门锁被暴力破解、窗户在非休息时间突然打开、或者长时间无人却有人活动的矛盾情况。所有设备状态变化均有合理的因果关联。"

  "key_evidence": [
    "[17:20] balcony_door_contact=False, balcony_light=True, balcony_laundry_washer=OperationalState=1 -> 正常家务活动",

    "[16:34-17:54] living_room_occupancy 多次变为 1 -> 人员在家活动",
    "[17:00-18:10] master_bedroom/second_bedroom_occupancy 持续为 0 -> 卧室无人，符合时间规律"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议关注厨房温度传感器在灶具使用期间的数据稳定性，若长期缺失可考虑更换传感器以完善环境监测。"
  ]
}
```
