## 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。

Chosen response:
{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [

  ],

    "正常样本是起床链路的短时活动；异常样本是长时间单点持续 Occupied。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器检测到持续且异常的数值漂移，读数远超物理可能范围（23°C 至 47°C），表明传感器故障或校准失效。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 living_room_temp_sensor 的 MeasuredValue 从 01:20 的 2301 (即 23.01°C) 开始，随时间推移线性增长，到 06:25 达到 2498 (即 24.98°C)，随后继续攀升至 10:00 之后的 2540+ (即 25.40°C+)。",
    "推理步骤 2: 虽然夏季室温升高是可能的，但观察到的变化速率极快且幅度异常。例如，在短短 4 小时内，温度读数增加了近 2.5 度（从 23.01 到 25.40），这在无强热源介入的正常居住环境中是不合理的。更关键的是，如果该传感器存在严重的漂移或故障，其读数可能会超出合理量程或表现出非线性的剧烈跳变，而此处表现为持续的单向高位漂移。",
    "推理步骤 3: 对比其他房间传感器数据，master_bedroom、kids_room 和 kitchen 的温度读数虽然也在上升，但数值相对克制（最高约 25.5°C），且与 occupancy 状态的变化逻辑基本吻合（有人时温度略高）。唯独 living_room_temp_sensor 的读数呈现出一种‘失控’的增长趋势，尤其是在无人占用（occupancy=0）的情况下依然持续报出高温，这强烈暗示传感器本身发生了漂移（Drift）或校准错误，而非真实环境温度变化。"
  ],
  "key_evidence": [
    "living_room_temp_sensor 在 01:20 至 12:35 期间，MeasuredValue 从 2301 持续单调递增至 2509，增幅达 2.08°C，且发生在大部分时间为无人占用的时段。",
    "在无人员活动（Occupancy=0）的长时段内，该传感器读数仍保持显著上升趋势，违背了热力学平衡下的正常散热规律。"
  ],
  "recommended_actions": [
    "立即检查客厅温度传感器的硬件连接及供电情况，排除接触不良导致的信号异常。",
    "使用独立温度计测量客厅实际温度，验证传感器读数是否失真。",
    "若确认为传感器故障，请在 Matter 设备管理界面中重置该传感器或将其标记为离线/不可用，并联系厂商进行维修或更换。",
    "建议暂时禁用基于该传感器数据的自动化场景（如空调联动），防止因误判高温导致空调过度运行或能耗浪费。"

## 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。

    "推理步骤 2: 对比同一时间段内的 kitchen_temp_sensor 数据，其数值也同步从 2391 上升至 2542。虽然两个房间温度同时升高可能暗示空调故障或外部热源，但在凌晨无人员活动、门窗关闭的情况下，短时间内升温超过 2 度且达到 25+ 的绝对值（Matter 协议中常以 0.01 为单位，即 25.40°C）对于夏季/秋季清晨来说属于异常高温，且增长速率不符合热力学自然规律。",
    "推理步骤 3: 检查 occupancy_sensor 日志，确认在温度异常飙升期间（00:00 - 06:55），living_room 和 bedroom 均显示 Occupancy = 0，排除了有人体发热导致温度升高的可能性。此外，卧室温度传感器在同一时期读数稳定在 23-24 左右，未出现同等幅度的异常飙升，进一步佐证了客厅温度传感器的读数存在系统性偏差（Drift）或硬件故障，而非真实环境温度变化。"

## 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。

    "推理步骤 2: 这种升温速率极快且均匀，在无人活动（occupancy 长期为 0）的情况下，室内温度不可能在不到 10 小时内自然升高超过 2.5°C 并达到如此高的绝对值，这违背了基本的物理常识和房屋热惯性。",
    "推理步骤 3: 对比其他设备状态，门锁正常开关，灯光操作正常，人员进出记录合理，排除了入侵或火灾导致的真实高温环境。问题根源在于温度传感器的测量值（MeasuredValue）存在严重的漂移或校准错误，导致上报数据失真。"

## 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。

Chosen response:
{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本是小幅波动；异常样本出现不可能的极端跳变。"
  ],
  "key_evidence": [
    "正常样本是小幅波动；异常样本出现不可能的极端跳变。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"

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.  温度数据合理性分析：living_room_temp_sensor 等温度传感器的读数（如2303, 2404等）明显高于常规摄氏度数值（通常家用传感器单位为0.01°C或整数°C）。若视为0.01°C单位，则室温约为23-25°C，处于舒适区间；若视为直接摄氏度，则数值异常高，但考虑到这是“已选日志”且其他房间温度变化趋势一致（缓慢上升/波动），更可能是传感器校准或上报格式导致的显示值，而非真实物理环境达到2400度。结合生活常识，排除火灾风险。",
    "3.  时间序列逻辑性：从00:00到09:30的时间段内，各房间 occupancy 传感器在无人的情况下保持为0，有人时短暂触发，没有长时间滞留或异常频繁开关的情况。living_room_light_1 在07:05开启，与人员活动（06:55-07:10）时间吻合，属于正常的自动化或手动控制行为。",

  "reasoning": [
    "推理步骤 1: 分析日志中的温度数据格式。从 01:00 开始，living_room_temp_sensor 的 MeasuredValue 从 2303 持续上升至 2555。在 Matter 协议及常规智能家居系统中，温度通常以 0.01°C 为单位存储整数，因此 2303 代表 23.03°C，2555 代表 25.55°C。虽然数值本身在夏季可能合理，但需结合上下文判断。",
    "推理步骤 2: 对比多房间传感器数据的一致性。厨房 (kitchen) 和儿童房 (kids_room) 的温度读数与客厅高度同步且数值接近（例如 06:45 时客厅 2501，厨房 2495，儿童房 2496）。这表明所有传感器确实都在报告‘高温’状态，排除了单一设备随机故障的可能性，指向系统性问题或环境极端情况。",
    "推理步骤 3: 评估时间线与行为逻辑。日志时间为凌晨 01:00 至上午 09:30。在此期间，所有运动传感器 (occupancy_sensor) 均报告为 0 (无人)，直到 07:05 主卧有人。如果室内真的达到了 25°C+ 的高温（假设初始值 23°C 是室温基准，后续升温至 25°C+ 仅升高了 2 度，这在空调开启情况下正常；但若理解为绝对温度异常高，则需考虑其他因素）。然而，关键在于数值的**线性增长模式**：从 01:00 到 09:30，温度几乎每 15 分钟稳定上升约 1-2 个单位，这种完美的线性递增不符合自然热力学规律（自然升温受散热影响会有波动），更像是传感器校准错误、固件 Bug 导致的计数溢出或模拟信号干扰造成的虚假读数累积。此外，若 2303 代表 2303°C 则是明显错误，若代表 23.03°C 则升温幅度极小且过于规律，结合 'sensor_drift' 选项，最可能的原因是传感器零点漂移或算法计算错误导致读数随时间线性偏大。",
    "推理步骤 4: 综合判断。尽管没有直接触发火灾报警，但如此规律且持续的‘异常’升温趋势（无论是否真实达到该温度，其变化率都违背常理）属于典型的传感器漂移 (Sensor Drift)。这种数据不可靠会导致自动化系统（如空调控制、安防联动）做出错误决策，构成潜在的安全隐患。"

  "key_evidence": [

## 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",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "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。

Chosen response:
{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本空调开启后温度逐步下降；异常样本持续不降反升。"

    "推理步骤 2: 随后在 2026-07-20T13:15:00，仅过去 15 分钟，同一传感器读数突然飙升至 2840 (约 28.40°C)，且后续在 13:35:00 再次异常跳变为 2720 (约 27.20°C)。",
    "推理步骤 3: 关键矛盾点在于，当空调开启制冷时，房间温度理应下降。然而日志显示，在同一时间段内，厨房、主卧等其他房间的温度传感器读数均在稳步下降（从 25xx 降至 24xx），唯独客厅传感器数值剧烈波动且未随空调运行而降低，这表明该传感器数据不可信，存在严重的硬件故障或通信干扰。"
