## 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": "sensor_malfunction",
  "threat_description": "洗衣机运行但倒计时不减少",
  "reasoning": [
    "推理步骤1: 运行状态为 Running",

    "推理步骤3: 与正常过程矛盾"
  ],
  "key_evidence": [

    "与正常过程矛盾"
  ],
  "recommended_actions": [
    "标记为运行状态/计时链路异常，建议检查洗衣机控制模块。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "目标设备 (balcony_laundry_washer) 运行状态正常，无安全威胁或异常行为。",
  "reasoning": [
    "推理步骤 1: 检查洗衣机状态日志。在 2026-07-17T10:00:00 记录到 OperationalState.OperationalState = 1 (运行中)，随后在 10:20:00、10:40:00、11:00:00 多次报告 CountdownTime = 2400 (剩余 40 分钟)。这表明设备正在按计划执行洗涤程序，且倒计时逻辑一致，未出现卡死或状态跳变。",
    "推理步骤 2: 结合环境上下文分析。日志显示入户门 (front_door_contact)、玄关及餐厅等多处传感器频繁检测到人员活动 (Occupancy=1)，且厨房温度随时间自然波动（符合日间升温规律），表明家庭处于正常的日常活跃状态，非入侵或异常静默场景。",
    "推理步骤 3: 排除其他风险。虽然任务说明中提到重点房间为 balcony，但日志中并未出现阳台门传感器异常开启、漏水报警或烟雾报警等关联事件。洗衣机的运行与周围环境数据相互印证，属于正常的家务活动模式。"
  ],
  "key_evidence": [
    "2026-07-17T10:00:00 | balcony_laundry_washer | OperationalState.OperationalState = 1",
    "2026-07-17T10:20:00 | balcony_laundry_washer | OperationalState.CountdownTime = 2400",
    "多时段 occupancy_sensor 报告显示家庭成员正常活动，环境数据符合日间规律"
  ],

## 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": "全屋温度传感器读数呈现不自然的线性持续上升趋势，且数值单位异常（疑似未转换为摄氏度），表明传感器存在系统性漂移或校准故障。",
  "reasoning": [
    "1. 数据单位异常分析：日志中的温度值（如2269, 2370, 2544）远超正常室温范围（通常15-30°C）。在Matter协议中，TemperatureMeasurement的MeasuredValue通常以厘氏度（centi-degrees Celsius）为单位，即除以100得到摄氏度。若按此标准，2269对应22.69°C，这是合理的初始室温。",
    "2. 趋势异常检测：从00:00到09:10，所有房间的温度读数均呈现出近乎线性的、持续的单向上升。例如主卧从22.94°C升至25.44°C，厨房从22.76°C升至25.44°C。在夜间至清晨时段，若无空调开启或外部热源介入，室内温度不应出现如此剧烈且同步的持续升温。",
    "3. 排除环境因素：虽然夏季清晨气温可能升高，但9小时内全屋各角落（包括无窗的卫生间、有遮光的卧室）温度同步上升近3°C且保持高位，不符合自然热惯性规律。更关键的是，如果这是真实升温，空调系统（living_room_ac, master_bedroom_ac）应有响应记录（如状态变化或功率调整），但日志中未显示任何空调动作，仅显示了温度读数的被动上报。",
    "4. 结论：这种全设备同步的、非物理规律的数值漂移，最可能的原因是传感器硬件故障、固件Bug导致的数据上报错误，或者传感器被放置在极端热源附近（但考虑到多房间同时发生，硬件/固件问题概率更高）。"
  ],
  "key_evidence": [
    "主卧温度传感器读数从01:05的2294 (22.94°C) 持续上升至09:10的2544 (25.44°C)，期间无人员活动（Occupancy=0大部分时间）且无空调干预。",
    "厨房、客厅、次卧等所有温度传感器在同一时间段内均表现出相似的线性上升趋势，排除了单一传感器局部受热导致的可能性。",
    "凌晨00:00至09:10期间，除主卧短暂有人外，其余区域 occupancy 均为 0，排除了人体散热导致的局部温度快速升高。"
  ],
  "recommended_actions": [
    "检查智能家居中枢或网关的固件版本，确认是否存在已知的温度数据解析Bug。",
    "对主要房间的温湿度传感器进行手动校准测试，对比手持式高精度温度计读数。",
    "检查传感器安装位置，确保没有靠近阳光直射窗口、暖气或其他热源。",
    "若校准无效，考虑更换疑似故障的温度传感器模块。"

## 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。

  "threat_description": "全屋温度传感器读数呈现非自然的线性持续上升，且数值单位异常（疑似未转换为摄氏度），表明传感器存在严重漂移或数据上报故障。",
  "reasoning": [
    "1. 数值单位异常分析：日志中的温度值（如2263, 2400, 2556等）远超正常室温范围（通常15-30°C）。在Matter协议中，TemperatureMeasurement.MeasuredValue通常以厘度（centi-degrees Celsius）为单位，即除以100得到摄氏度。若按此换算，初始值为22.63°C，这是合理的；但后续数值持续上升至25.56°C以上，且所有房间同步变化，需结合趋势判断。",
    "2. 趋势异常分析：从00:00到11:05，所有房间的温度传感器读数均呈现出近乎完美的线性单调递增趋势（例如主卧从2275升至2549，厨房从2281升至2544）。在夜间至清晨时段，若无空调加热或极端天气影响，室内温度不可能在所有房间同时、同速地持续升高超过3度。这种缺乏波动、完全线性的增长不符合热力学自然规律。",
    "3. 排除环境因素：虽然夏季白天温度可能上升，但凌晨00:00-06:00通常是气温最低或平稳期，不应出现如此剧烈的持续升温。此外，各房间温差极小（始终保持在几度以内），且变化速率高度一致，这更像是传感器内部校准错误、固件Bug导致的计数溢出/漂移，或者是模拟数据生成时的算法缺陷，而非真实的物理环境变化。"
  ],
  "key_evidence": [
    "所有房间温度传感器（living_room, master_bedroom, kitchen, kids_room等）在00:00至11:05期间读数持续单调递增，无任何下降或波动。",
    "温度变化曲线过于平滑和线性，例如master_bedroom_temp_sensor从2275(22.75°C)线性增至2549(25.49°C)，每小时增幅约2-3个单位，不符合自然热惯性。",
    "不同位置（如厨房与卧室）的温度读数高度相关且同步变化，排除了局部热源干扰的可能性。"
  ],
  "recommended_actions": [
    "检查智能家居平台后端对TemperatureMeasurement数据的解析逻辑，确认是否错误处理了单位转换（如将毫度误认为厘度，或反之）。",
    "对涉事温度传感器进行重置或固件升级，排查是否存在硬件故障导致的数据漂移。",
    "对比气象站或室外真实温度数据，验证室内传感器读数是否与外部环境趋势背离。"

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",

  ],
  "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。

    "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2920、2940、2960的数值（对应约29.2°C-29.6°C）。",
    "3. 排除环境因素：同一时间段内，其他所有房间的温度传感器均显示温度正在下降（从~25°C降至~24°C以下），且客厅空调在13:00开启，通常会导致温度降低而非升高。因此，这并非真实的环境升温。",
    "4. 确认故障模式：异常读数呈现明显的周期性（每隔20分钟一次）且数值偏高但非极端（未超过30°C），符合传感器内部电路干扰、ADC转换错误或固件Bug导致的“假阳性”高温读数特征，属于典型的传感器 malfunction。"

## 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。

    "推理步骤 2: 随后厨房温度传感器读数急剧上升，从正常的约 23°C (2315 mK) 迅速攀升至 26.76°C (2676 mK)，并在短时间内达到峰值 26.76°C (2676 mK) 甚至更高（日志显示数值如 2604, 2676），远超正常烹饪时的环境温度波动范围，表明局部过热严重。",
    "推理步骤 3: 关键异常在于 2026-07-15T19:28:30，厨房窗户传感器状态变为 False (打开)。在灶具高温运行期间窗户被打开，这极不寻常：如果是为了通风降温，通常不会伴随如此剧烈的温度读数异常；更可能的情况是有人试图逃离烟雾/热气而开窗，或者入侵者利用此机会制造混乱并接近热源，亦或是设备本身发生严重故障导致过热报警。结合温度持续高位和窗户开启，火灾风险极高。"

    "分析日志发现，2026-07-03T14:05:00时，living_room_temp_sensor 报告的 TemperatureMeasurement.MeasuredValue 为 -500。",
    "根据 Matter 协议标准，TemperatureMeasurement Cluster 的 MeasuredValue 单位为厘氏度（centi-degrees Celsius），即实际温度 = 值 / 100。因此 -500 代表 -5.0°C。",
    "对比同一时间点（14:00）及前后时间点的其他房间温度（如主卧约24.7°C，厨房约24.7°C，儿童房约24.6°C），客厅正常温度应在24°C左右。-5.0°C 与家庭环境严重不符，且远低于冰点，属于物理上不可能的极端低温（除非传感器被置于冰箱内，但这不符合客厅场景）。",
    "虽然14:10读数恢复至24.40（24.4°C），看似恢复正常，但这种从正常值到极端负值的瞬间跳变是典型的传感器故障、ADC转换错误或数据包损坏特征，而非真实的环境变化。"
