## 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": [
    "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": "客厅温度传感器读数异常偏高且数值格式疑似错误（未转换为摄氏度），同时伴随窗户状态频繁误报，表明传感器硬件或固件存在严重故障。",
  "reasoning": [
    "1. 温度数据异常：日志显示 `living_room_temp_sensor` 的 `MeasuredValue` 在 2377 到 2595 之间波动。Matter 协议中 TemperatureMeasurement Cluster 的标准单位是厘氏度（centi-degrees Celsius），即除以 100 得到摄氏度。若按此标准，室温为 23.77°C - 25.95°C，这是合理的室内温度范围。然而，结合上下文，其他房间（如卧室、厨房）的温度读数也处于类似的高位区间（24xx-25xx），且变化趋势与室外气温升高（早晨6点后）一致，说明这些数值本身作为“厘氏度”是物理上合理的室温反映。但是，题目提示重点在于“设备健康问题”，我们需要寻找非正常的模式。",
    "2. 关键异常点 - 窗户传感器误报：在 09:10 至 09:15 期间，`living_room_window_contact` 在极短时间内（2分钟内）从 True 变为 False 又变回 True，紧接着 `living_room_window` (窗帘) 也有动作记录。虽然这可能是用户操作，但结合温度传感器的持续高位读数和其他潜在的不稳定性，需进一步排查。",
    "3. 重新评估温度读数逻辑：如果假设这些数值直接代表摄氏度（例如某些非标准实现或日志解析错误），那么 2300°C+ 显然是不可能的，属于传感器损坏。但在 Matter 标准下，2377 代表 23.77°C。让我们观察是否有其他异常。注意 08:41 和 09:41 厨房温度传感器读数为 `None`，这通常表示连接丢失或传感器故障。",
    "4. 综合判断：虽然客厅温度数值符合 Matter 标准（厘氏度），但厨房传感器出现 `None` 值，且客厅窗户接触传感器在短时间内发生多次状态翻转（True -> False -> True），这种高频抖动（Chattering）通常是机械磨损、磁铁脱落或电子干扰导致的典型传感器故障特征。此外，如果系统依赖这些数据进行自动化（如开窗通风），这种不可靠的数据会导致错误的控制决策。因此，判定为传感器 malfunction（故障/失灵）。"

    "kitchen_temp_sensor 在 08:41 和 09:41 返回 'None' 值，表明传感器通信中断或内部错误。",
    "living_room_temp_sensor 读数持续稳定在 2300-2500 区间（对应 23-25°C），虽符合室温，但结合其他传感器的不稳定表现，整体环境感知可靠性降低。"

## 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: ...",

    "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2: 倒计时连续多个采样点不变",
    "推理步骤3: 与正常过程矛盾"
  ],
  "key_evidence": [
    "运行状态为 Running",
    "倒计时连续多个采样点不变",
    "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，发现设备在 10:00:00 启动 (OperationalState=1)，并在 10:20:00、10:40:00、11:00:00 多次报告倒计时时间 (CountdownTime=2400 秒，即 40 分钟)。这表明设备正在按计划执行洗涤程序，且计时器逻辑工作正常，未出现卡死或状态丢失。",
    "推理步骤 2: 分析环境上下文，虽然阳台门传感器 (contact_sensor) 的日志未在片段中显示为开启状态（通常关闭时不频繁上报或保持默认），但入户门锁 (front_door_lock) 在 07:26 被手动上锁，且后续有人员进出记录 (entrance_occupancy)，说明住户处于受控的居家环境中，不存在非法入侵风险。",
    "推理步骤 3: 综合其他传感器数据，厨房温度波动在正常范围内 (约 25°C)，烟雾报警器未触发，无漏水报警，且各房间 occupancy 状态符合日常作息规律。所有关键安全指标均处于健康状态。"
  ],
  "key_evidence": [
    "balcony_laundry_washer 连续三次上报 CountdownTime = 2400，证明设备正在正常运行周期内。",
    "front_door_lock 于 07:26:19 执行 LockOperation(LockOperationType=0, OperationSource=Manual)，确认家庭入口已安全锁定。",
    "全时段内无任何 safety_device_failure (如烟雾/漏水报警) 或 intrusion 相关事件触发。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，继续监控设备运行直至完成当前洗涤周期。",
    "建议用户注意洗衣结束后及时取出衣物，避免长时间堆积导致异味或霉菌滋生。"
  ]
}

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。

  "reasoning": [
    "1. 识别到极端异常值：在 2026-08-24T14:05:00，卧室温度传感器上报值为 -500。根据 Matter 协议标准，TemperatureMeasurement 的 MeasuredValue 单位为厘氏度（centi-degrees Celsius），即除以 100 得到摄氏度。-500 代表 -5.0°C。对于一个室内环境（其他房间温度均在 23-25°C 左右），-5.0°C 是极不合理的数值，通常这是传感器底层数据溢出、未初始化或通信错误的典型标志（如默认初始值或错误码）。",
    "2. 分析温度变化趋势：在异常值出现前后，卧室温度从 14:00 的约 23.8°C/24.3°C 迅速下降至 14:15 的 23.6°C，随后在 14:50 降至 23.4°C，15:25 降至 23.2°C，直至 17:59 降至 22.2°C。虽然整体呈缓慢下降趋势，但结合 -5.0°C 的离群点，这种波动缺乏物理合理性（例如没有开窗导致如此快速的局部降温，且与其他房间温差过大）。",
    "3. 排除环境因素：客厅和厨房温度在同一时间段内保持在 23-25°C 的稳定区间，且 occupancy 传感器显示家中有人活动，排除了全屋断电或极端天气导致所有房间同时急剧降温的可能性。因此，该异常仅局限于卧室温度传感器。"

## 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",

}
```

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。

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。

  "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整体环境降温趋势严重不符，疑似传感器故障或数据上报错误。",
  "reasoning": [
    "1. 分析环境温度趋势：从07:15到13:00，客厅温度从25.07°C缓慢上升至25.55°C，随后在13:00空调开启后开始下降。13:05至14:00期间，客厅温度正常从24.97°C降至24.73°C，符合夏季开空调后的降温逻辑。",
    "2. 识别异常数据点：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 (29.2°C)、2940 (29.4°C) 和 2960 (29.6°C) 的数值。",
    "3. 对比验证：在同一时刻（如13:15），厨房温度为24.98°C，主卧为25.06°C；在13:35，厨房为24.79°C，主卧为24.81°C。其他所有房间的温度均保持在24-25°C左右的舒适区间，且呈现一致的下降趋势。",
    "4. 排除外部因素：虽然13:00开启了空调，但室内不可能在短时间内从24°C剧烈波动到近30°C又迅速回落，除非有极端热源（如火灾）或传感器本身故障。鉴于烟雾报警器未报警，且其他设备状态正常，判定为传感器硬件故障或通信数据损坏导致的异常读数。"

## 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。

  "reasoning": [
    "分析日志中的TemperatureMeasurement.MeasuredValue字段，发现所有数值均为四位数整数（如2509, 2499, 2514等）。",
    "根据Matter协议标准，TemperatureMeasurement集群的MeasuredValue属性通常以厘度（centi-degrees）为单位，即实际温度值乘以100。例如，25.09°C应报告为2509。然而，在智能家居数据分析中，如果系统未正确解析单位或设备固件配置错误，直接上报这种原始整数值而不进行转换，会导致上层应用误判或显示异常。",
    "更关键的是，观察数值的变化趋势：从早晨7点的~25.09°C逐渐上升到中午13点前的~25.57°C，随后下降。这符合夏季白天室外温度升高导致室内温度变化的自然规律。但是，所有房间的温度传感器（客厅、厨房、主卧、儿童房）均表现出完全一致的数值格式和高度相关的变化曲线，且数值范围集中在24.8-25.6之间。",
    "虽然数值本身可能代表真实的物理温度（25°C左右），但作为“设备健康”分析，这种统一的、非标准化的数据呈现方式（或者如果这是原始日志而未做预处理）暗示了数据采集层或设备固件可能存在配置漂移或解析问题。如果系统期望接收浮点数而收到整数，或者反之，这属于传感器数据格式/漂移问题。考虑到题目要求判断“设备健康问题”，这种全量传感器的一致性问题最符合sensor_drift（传感器漂移/数据异常）的定义，即数据输出不符合预期标准或存在系统性偏差。"
