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
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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": "high",

  "threat_description": "客厅温度传感器出现间歇性极高读数异常，疑似硬件故障或数据上报错误。",
  "reasoning": [
    "1. 分析温度数据趋势：在2026-07-03的大部分时间里，客厅及其他房间的温度传感器读数呈现正常的昼夜变化规律（从早晨的~25°C逐渐下降至傍晚的~23°C），且各房间温差合理（例如主卧、厨房、儿童房读数相近）。",
    "2. 识别异常点：在13:15、13:35和13:55三个时间点，客厅温度传感器（living_room_temp_sensor）突然上报了2920、2940、2960的数值。根据Matter协议标准，TemperatureMeasurement.MeasuredValue的单位是厘氏度（centi-degrees Celsius），即除以100得到摄氏度。因此这些读数为29.2°C、29.4°C、29.6°C。",
    "3. 排除环境因素：虽然29°C比环境温度略高，但考虑到此时空调已开启（13:00 OnOff=True），且其他所有邻近区域（如餐厅、主卧、厨房）的温度均在24-25°C左右并持续下降，客厅局部瞬间升温近5度且随后又迅速回落至正常范围（14:05变为24.63°C），这不符合物理热惯性规律。",
    "4. 判定故障类型：这种短时间内剧烈波动后恢复正常的现象，极大概率是传感器内部元件故障、ADC转换错误或通信数据包损坏导致的“毛刺”信号，属于典型的传感器硬件或固件层面的偶发性故障。"

  ],
  "recommended_actions": [

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

  "threat_description": "客厅温度传感器出现间歇性极高数值读数（约29.2°C-29.6°C），与同一时间段内其他房间及厨房的平稳温度趋势严重不符，且该异常值在空调开启后迅速消失，判定为传感器故障或数据上报错误。",
  "reasoning": [
    "1. 建立基准：分析日志发现，从07:00到13:00，客厅、厨房和卧室的温度呈现一致的缓慢上升趋势（例如13:00时，客厅24.97°C，厨房25.04°C，卧室23.92°C），这符合夏季白天室内温度随室外升温的自然规律，表明环境整体处于正常升温状态。",
    "2. 识别异常点：在13:15、13:35和13:55三个时间点，客厅温度传感器突然上报了29.20°C、29.40°C和29.60°C的数值。此时段内，距离相近的厨房温度仅为25.07°C-24.73°C，卧室温度为23.90°C-23.81°C。在同一密闭或半密闭的一室一厅环境中，相邻区域存在近5°C的巨大温差极不符合物理常识。",
    "3. 关联设备状态验证：13:00时客厅空调开启（OnOff=True）。在空调运行初期，虽然室温会下降，但不会导致局部瞬间飙升。更重要的是，在13:15异常高值出现后，随后的读数（如13:25的24.86°C）迅速回落至与其他房间一致的正常范围（~24.8°C）。这种“瞬时尖峰”随后立即恢复正常且无持续高温特征的模式，是典型传感器硬件故障、校准漂移或通信数据包错误的特征，而非真实的环境温度变化。"

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

  "reasoning": [
    "1. 分析时间序列数据：在 12:00 时，厨房温度传感器读数为 2535 (25.35°C)，这与客厅(25.19°C)和卧室(24.21°C)的温度处于合理且一致的夏季室内环境范围内。",
    "2. 识别异常点：在 12:10 时，同一厨房温度传感器的读数突然变为 2727 (27.27°C)。这一变化幅度为 +1.92°C，且在短短10分钟内发生，缺乏合理的物理过渡过程（如空调关闭或门窗大开通常不会导致如此剧烈的瞬时升温）。",
    "3. 排除其他因素：虽然 12:01 厨房灯开启，但灯具产生的热量不足以在10分钟内使整个房间温度上升近2度并达到27.27°C的显著高位，尤其是考虑到之前几分钟温度稳定在25.3-25.4°C左右。",
    "4. 确认恢复情况：在 12:15 及之后的记录中，未提供新的厨房温度数据，但结合上下文，这种单点的、非渐进式的数值跳变是典型的传感器电子故障、校准漂移或瞬时电磁干扰特征，而非真实的环境温度变化。"

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

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
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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。

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
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

请按以下 JSON 格式回答：

```json

  "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。

    "1. 分析时间序列数据：在 2026-08-12T19:15:00 之前，厨房温度传感器读数稳定在 2300-2320 (约 23.0-23.2°C) 之间，与客厅和卧室温度趋势一致（缓慢下降）。",
    "2. 识别异常点：在 19:15:00，厨房温度突然飙升至 2551 (25.5°C)，随后在 19:35:00 进一步激增至 2684 (26.8°C)。",
    "3. 排除正常环境变化：同一时间段内，客厅温度从 2287 降至 2265，卧室温度从 2189 降至 2174，均呈正常降温趋势。厨房作为独立空间，若无剧烈烹饪行为（日志中未显示灶具开启或烟雾报警），不应出现与其他房间完全背离的急剧升温。",
    "4. 关联事件分析：虽然 19:34:30 厨房窗户关闭，但这通常会导致温度略微上升或保持，不会导致短时间内从 ~23°C 跃升至 ~26.8°C 且伴随后续数据的剧烈波动（19:55 又降至 25.6°C）。这种非线性的、大幅度的数值跳跃符合传感器故障（如内部电路问题、校准丢失）或传感器被极端局部热源（如刚关火的锅直接靠近）干扰的特征。鉴于其他房间正常，判定为传感器自身问题可能性最大。"
