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",

    "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，所有设备活动符合正常的家庭作息规律。",
  "reasoning": [
    "1. **作息模式一致性分析**：对比2026-08-10至08-12三天的日志，住户的起床时间（主卧/客厅 occupancy 变为 1）均集中在早晨 06:00-07:30 之间，且温度传感器读数随日照逐渐上升，符合典型的白天活动模式。夜间（00:00-05:00）各区域 occupancy 均为 0，表明住户处于睡眠状态，无异常闯入迹象。",
    "2. **厨房安全行为正常**：虽然 08-11 和 08-12 早上有灶具开启或灯光操作，但随后不久（如 08-11 07:21 开窗通风，08-12 06:42 开灯后无长时间无人看管记录）即有相应的环境调整动作，且未见烟雾报警器触发或长时间无人烹饪导致的过热风险。特别是 08-11 在灶具使用后打开了厨房窗户，这是良好的安全习惯。",
    "3. **门锁与出入记录逻辑自洽**：08-10 早上 07:10 有人手动解锁并离开（LockState 变化），08-11 早上 07:32 有人手动上锁并进入（LockState=1, Entrance Occupancy=1）。这些时间点与住户起床后的活动时间吻合，属于正常的离家/回家行为，不存在暴力破解或异常频繁开关门的迹象。",
    "4. **传感器数据稳定性**：温度传感器数值在合理范围内波动（约 24°C - 25°C），没有出现突变的极端值或长期停滞不前的“卡死”现象，排除了传感器故障导致误报的可能性。"
  ],
  "key_evidence": [

    "推理步骤 2: 在窗户打开期间及之后，厨房和客厅的温度传感器读数急剧上升（从约 24°C 升至 25.3°C+），这种升温速率远超正常环境变化，暗示有热源持续作用或通风不良导致热量积聚。",
    "推理步骤 3: 虽然住户随后锁门离开，但‘烹饪时开窗’结合‘高温报警’是典型的火灾隐患模式（可能涉及燃气泄漏遇明火、油烟起火或设备过热）。相比之下，其他房间活动正常，排除了入侵或尾随的可能性。"

## 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",

  ],
  "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "检测到阳台门关闭、灯光开启及洗衣机启动，结合多房间人员活动日志，判断为住户正常的居家洗衣行为，无安全风险。",
  "reasoning": [
    "1. 分析核心事件链：在 17:20:00，阳台门传感器显示状态为 False（通常代表关闭/锁定），紧接着阳台灯开启 (True)，随后洗衣机启动 (OperationalState = 1)。这一序列符合‘人进入阳台区域 -> 关门 -> 开灯 -> 操作洗衣机’的正常逻辑。",
    "2. 验证人员存在性：在 17:25:00 的日志中，主卧、儿童房、玄关和餐厅的运动传感器均报告 Occupancy = 1。这表明家中有多名成员处于活跃状态，排除了‘空巢’或‘非法入侵者独自行动’的可能性。",
    "3. 排除异常模式：阳台门在洗衣机启动前已关闭，说明并非门窗未关导致的安全隐患；洗衣机启动时间（17:21）与人员活动高峰吻合，非深夜无人值守时的异常运行；无烟雾、漏水或门锁故障报警。"

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. **关键事件逻辑验证**：8月3日07:20左右，记录到 bedroom_light 关闭 -> front_door_lock 解锁(2) -> front_door_contact 开启(True) -> front_door_lock 上锁(1)。这一序列清晰地表明住户离开家并锁门，属于正常的离家行为，而非入侵或非法进入。",
    "3. **传感器数据合理性**：温度传感器读数（如2448代表24.48°C）随时间缓慢变化，且夜间无人员活动时温度稳定，有人活动时略有波动，未见跳变或停滞，排除传感器故障。Occupancy传感器在夜间为0，清晨依次唤醒，符合人体感应逻辑。",
    "4. **无危险迹象**：厨房灶具(cook_surface)和烟雾报警器(smoke_co_alarm)在日志期间未触发任何报警或异常状态；门窗传感器仅在正常出入时触发；无漏水或一氧化碳风险迹象。"

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

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

    "2.  occupancy 分布合理性：日志中主卧、儿童房、玄关和餐厅的运动传感器持续显示 Occupancy=1，而客厅和次卧显示 Occupancy=0。这种分布符合典型的傍晚时段家庭活动模式（如孩子在房间学习/玩耍，大人在卧室休息或准备晚餐，玄关有人员进出迹象），未发现长时间无人却频繁触发或长时间有人却无互动的异常情况。",
    "3. 温度数据稳定性：所有温度传感器的读数在 23.3°C - 23.8°C 之间波动，变化幅度极小且符合室内恒温环境的特征，没有突变的极端值，排除了传感器故障或火灾风险。",

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。

  "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。

    "2. 人员活动轨迹符合常理：运动传感器在客厅、餐厅、主卧、儿童房等区域有规律地触发，且存在明显的“有人”到“无人”再到“有人”的切换，表明家庭成员在家中正常移动，无长时间静止不动导致的跌倒风险或异常静默。",
    "3. 无危险设备状态：日志中未涉及厨房灶具、烟雾报警器、漏水传感器等关键安全设备的报警或异常状态，排除了火灾、燃气泄漏或水浸风险。",

## 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",

  ],
  "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。

    "2. 人员活动模式分析：运动传感器数据显示住户主要在主卧和玄关区域活动（Occupancy=1），且时间间隔规律（约每15-20分钟出现一次活动记录），符合人在家中休息或进行日常活动的特征，未发现长时间静止（可能跌倒）或异常的大范围移动。",
    "3. 环境参数稳定性：温度传感器读数在 23°C - 24°C 之间波动，属于舒适的室内环境温度，且变化平缓，无火灾或极端天气导致的剧烈温升。",
    "4. 缺乏危险信号：日志中未包含烟雾报警器、漏水传感器或一氧化碳报警器的触发事件，也未发现门锁被暴力破解或异常开锁的记录。"

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。
