## 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",

  ],
  "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. 结合环境背景分析合理性：同日其他房间（客厅、厨房）的温度传感器读数均在 23°C - 25°C 之间（例如 14:25:00 living_room 为 2461/24.61°C）。对于独居老人的住宅，室内环境温度不可能在短时间内从正常的 ~24°C 骤降至 -5°C 且未触发空调制热或窗户开启等关联事件，这违背物理常识。",
    "3. 确认故障模式：紧随其后 [2026-07-07T14:10:00]，该传感器读数恢复至正常范围（2379/2440），但中间夹杂了瞬间跳变。这种极值（-500）通常是传感器内部ADC转换错误、固件崩溃或通信数据包损坏导致的典型“坏数据”特征，而非真实的环境变化。"

## 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",
  "reasoning": [
    "推理步骤1: ...",

    "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": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器读数异常且随后丢失信号，疑似硬件故障或通信中断。",
  "reasoning": [
    "1. 观察日志中 kitchen_temp_sensor 的温度读数变化：从 00:10 的 2283 到 07:20 的 2524，数值呈现持续、单调且大幅度的上升趋势（约 241 个单位）。在正常的家庭环境中，即使考虑昼夜温差或设备发热，短时间内如此剧烈且线性的升温极不符合物理规律，通常暗示传感器内部元件故障或校准严重漂移。",
    "2. 关键异常点出现在 07:08:09，kitchen_temp_sensor 报告 TemperatureMeasurement.MeasuredValue = None。这表明传感器不仅读数错误，还发生了数据丢包或完全离线，进一步证实了设备存在功能性故障。",
    "3. 尽管 07:20 后读数恢复为 2524，但结合之前的 'None' 状态和长期异常的高温趋势，可以判定该传感器处于不稳定或损坏状态，而非真实的环境温度反映。"
  ],
  "key_evidence": [
    "kitchen_temp_sensor 在 00:10-07:20 期间温度值从 2283 持续线性上升至 2524，违背正常热力学常识。",
    "kitchen_temp_sensor 在 07:08:09 返回 MeasuredValue = None，表明通信中断或传感器失效。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的电池电量及网络连接状态。",
    "尝试重置或重新配对该温度传感器；若问题依旧，建议更换传感器硬件。",
    "暂时忽略该传感器的温度数据，避免触发错误的空调或报警逻辑。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_stuck",
  "threat_description": "运动传感器持续报 Occupied",
  "reasoning": [
    "推理步骤1: 日志中出现了不存在的额外报警事件。"
  ],
  "key_evidence": [
    "我假设看到了一个未在日志中出现的 critical 告警。"
  ],
  "recommended_actions": [
    "判断为占用传感器卡死，建议检修或重置。"

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。

  "reasoning": [
    "1. 分析温度数据的合理性：日志中所有温度传感器的 `MeasuredValue` 均为整数（如 2268, 2305 等）。根据 Matter 协议标准，TemperatureMeasurement Cluster 的 `MeasuredValue` 通常以厘氏度（centi-degrees Celsius）为单位存储。因此，2268 代表 22.68°C，这是正常的室内环境温度。然而，从凌晨 00:00 到早上 09:40，所有房间的温度均呈现出单调、线性的持续上升趋势（从 ~22.7°C 升至 ~25.5°C），这在短短 10 小时内上升近 3°C 且无下降趋势，不符合典型的家庭昼夜温度变化规律（夜间应稳定或略降，清晨可能回升但不会如此剧烈且单向），暗示可能存在系统性偏差或传感器校准问题，但更明显的异常在于特定设备。",
    "2. 识别关键故障点：在 [2026-07-06T07:30:00]，`kitchen_temp_sensor` 的报告值为 `None`。在智能家居系统中，传感器返回 `None` 或空值通常意味着设备离线、电池耗尽、通信链路中断或内部硬件故障导致无法读取数据。",
    "3. 验证数据一致性：在 `None` 值前后，厨房温度读数也表现出与其他房间不同的行为模式。例如，07:00 为 2497/2497，07:30 为 None，08:30 跳至 2545，08:40 为 2550。虽然整体趋势一致，但中间的数据缺失是明确的故障证据。结合其他传感器工作正常（有数值返回），可以排除全屋网络瘫痪的可能，定位为厨房温度传感器的局部故障。"

    "尝试重启该传感器或重新配网，若问题依旧，建议更换传感器硬件。",
    "检查厨房环境是否有极端热源干扰或传感器安装位置不当导致的读数漂移（尽管主要问题是数据丢失）。"

## 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",
  "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。

  "threat_description": "厨房温度传感器读数出现剧烈且不合逻辑的波动，疑似传感器故障或受到灶具直接热辐射干扰。",
  "reasoning": [
    "1. 分析厨房温度数据：在 19:00 时读数为 2292 (22.92°C)，但在 19:10 灶具开启后，读数迅速飙升至 2486 (24.86°C)，并在 19:30 达到峰值 2675 (26.75°C)。随后在 19:35 又骤降至 2280 (22.80°C) 左右。",
    "2. 评估物理合理性：虽然烹饪会产生热量，但普通家用厨房的温度传感器通常安装在天花板或高处，距离灶具有一定距离，且空气对流需要时间。从 22.9°C 到 26.7°C 的急剧上升（近4度）并在半小时内回落至正常室温，这种‘尖峰’形态不符合典型的热惯性规律，更像是传感器受到了局部强热源（如明火、烤箱门打开时的热气直冲）的直接冲击，或者传感器本身存在漂移/故障。",
    "3. 对比其他设备：同一时间段内，客厅和卧室的温度变化平稳缓慢（例如客厅从 22.9°C 缓慢降至 22.5°C），符合夜间自然降温趋势。唯独厨房传感器数据异常跳变，排除了全屋环境突变的可能性。",
    "4. 结合烟雾报警器状态：日志中未触发 smoke_co_alarm，说明没有检测到严重的燃烧产物浓度超标，进一步佐证了这更可能是温度传感器的读数异常而非真实的火灾风险，但仍需警惕因传感器位置不当导致的误报或漏报隐患。"

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。

## 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",
  "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。

  "threat_type": "none",
  "threat_description": "目标设备 living_room_light_1 状态正常，无安全威胁或异常行为。",
  "reasoning": [
    "推理步骤 1: 检查目标设备日志，发现 living_room_light_1 在 20:10:00 被设置为关闭 (OnOff=False) 并调至低亮度 (Level=180)，随后在 20:12:00 再次确认关闭状态。该操作符合用户主动调整灯光的习惯性行为。",
    "推理步骤 2: 分析上下文环境，日志显示入户门传感器 (front_door_contact) 在 17:56 变为 False（开门），且多个房间（客厅、餐厅、厨房、儿童房等）的 occupancy_sensor 频繁报告有人 (Occupancy=1)，表明家庭处于活跃居住状态，非无人值守场景。",
    "推理步骤 3: 验证时间逻辑，事件发生在晚间 20:10 左右，属于正常的居家生活时段。温度传感器数据平稳下降，无火灾风险迹象；门锁状态未出现异常开启或卡死记录。所有设备行为均符合 Matter 协议下的正常交互模式。"
  ],
  "key_evidence": [
    "living_room_light_1 在 20:10:00 和 20:12:00 连续报告 OnOff=False，显示设备响应正常且处于预期关闭状态。",
    "entrance_occupancy 和 dining_room_occupancy 等多处传感器持续报告 Occupancy=1，证实室内有人活动，排除了误报或异常入侵的可能性。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续保持对多房间 occupancy 传感器的监控，以辅助判断家庭成员分布。"
