## 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": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",

  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数严重偏离物理现实，显示异常高温（22.9°C-25.5°C），而卧室和厨房温度正常，表明传感器存在漂移或故障。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从凌晨 01:10 开始，living_room_temp_sensor 的 MeasuredValue 持续上升，数值范围在 2293 到 2558 之间。若单位为毫开尔文 (mK)，则对应约 22.9°C 至 25.6°C；若为摄氏度直接记录，则意味着室内温度高达 2500°C+，这在普通住宅中是不可能的。",
    "推理步骤 2: 对比同一时间段内的其他房间数据，bedroom_temp_sensor 和 kitchen_temp_sensor 的读数稳定在 2300-2550 区间（对应约 23°C-25°C），且与人体活动规律相符（早晨起床后温度略有波动）。这表明房屋整体环境温度处于正常舒适范围，并非真实的高温环境。",
    "推理步骤 3: 结合住户背景（独居老人），如果客厅真的达到 25°C+（假设单位是 mK 但实际空调失效导致过热）或者传感器完全损坏报出错误值，对于独居老人来说存在健康风险或设备误报风险。鉴于其他传感器正常，最合理的解释是 living_room_temp_sensor 发生了严重的读数漂移（Drift）或校准错误，而非真实火灾或高温。"
  ],
  "key_evidence": [
    "living_room_temp_sensor 读数从 2293 线性上升至 2558，与其他房间正常的 ~2300-2400 基准值形成巨大反差。",
    "在同一时间窗口内，bedroom 和 kitchen 的温度传感器读数稳定且合理，排除了全屋性高温的可能性。",
    "没有触发烟雾报警器 (smoke_co_alarm) 或漏水报警，进一步佐证了非真实火灾或极端环境事件。"
  ],
  "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漂移。",
    "使用独立温度计测量客厅实际温度，验证传感器读数是否准确。",
    "若确认为传感器故障，建议更换该传感器或重置 Matter 设备以恢复出厂校准。",
    "通知住户注意观察，避免因虚假高温警报产生恐慌，同时提醒老人注意实际体感温度以防空调误关。"

## 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: ...",

    "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": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或设备故障，日志显示为正常的家庭日常活动及设备运行状态。",
  "reasoning": [
    "1. 洗衣机运行正常：阳台洗衣机在 10:00 启动（OperationalState=1），并在 10:20 和 10:40 分别报告剩余时间 2400秒和 1200秒，符合典型的洗涤程序倒计时逻辑，最终在 11:00 停止（OperationalState=0）。整个过程无异常中断或错误代码。",
    "2. 人员活动规律且合理：主卧运动传感器在大部分时间段（07:05-13:40）持续检测到人（Occupancy=1），表明住户主要在卧室休息或活动。玄关/入户门区域频繁出现短暂的人体存在信号（如 07:51, 08:36, 09:31 等），结合门锁在 07:41 上锁的状态，推测为住户在家中的正常走动或短暂查看门口，并非非法入侵。",
    "3. 环境数据稳定：各房间温度传感器读数在 2470mK (24.7°C) 到 2558mK (25.6°C) 之间波动，变化平缓，符合夏季室内空调或自然通风下的正常温度范围，无剧烈跳变暗示传感器故障。",
    "4. 门窗状态正常：入户门在 07:41 关闭并上锁，后续日志中未出现非授权开启记录。其他窗户和门的传感器未在异常时间触发报警。"
  ],
  "key_evidence": [
    "balcony_laundry_washer OperationalState 从 1 变为 0，中间有 CountdownTime 递减过程，符合正常洗衣流程。",
    "master_bedroom_occupancy 长时间保持为 1，符合居家休息场景。",
    "entrance_occupancy 多次短暂触发，但无对应的 door_lock 解锁或 front_door_contact 打开事件，排除入侵可能。",
    "temperature_sensor 数值在合理范围内缓慢波动，无突变。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控洗衣机运行结束后的状态，确保其完全断电或进入待机模式。"
  ]
}
```

{
  "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。"
  ],
  "key_evidence": [
    "正常样本倒计时递减并停止；异常样本数值长时间固定。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"

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",
  "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": 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: 正常样本是起床链路的短时活动；异常样本是长时间单点持续 Occupied。"
  ],
  "key_evidence": [
    "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。"
  ],

  "threat_description": "客厅温度传感器读数严重偏离物理现实，显示异常高温（23°C -> 25.5°C），且与住户正常活动模式（早晨起床、开门）的时间线不匹配，表明传感器存在漂移或故障。",
  "reasoning": [
    "推理步骤 1: 分析时间线与行为逻辑。日志显示在 06:53 至 07:17 期间，卫生间和主卧有人活动，随后入户门锁解锁并检测到人员进入玄关（07:17）。这是典型的早晨起床、洗漱、出门上班的正常家庭作息流程。",
    "推理步骤 2: 评估环境状态合理性。在此过程中，厨房灯开启（07:02），但并未进行烹饪操作（灶具未报告状态变化，且无烟雾报警）。然而，从 01:00 到 09:17，客厅温度传感器读数从 23.02°C 持续线性上升至 25.45°C，并在短时间内达到 25.5°C 以上。",
    "推理步骤 3: 识别异常模式。在没有明显热源（如长时间开空调加热、大量人员聚集、火灾迹象）的情况下，室内温度在不到 9 小时内上升超过 2.5°C 是不符合常理的。更关键的是，该升温趋势贯穿了整夜无人时段（00:00-06:00），这排除了人为活动导致升温的可能性，极大概率是传感器校准失效（Drift）或硬件故障导致的读数虚高。"
  ],
  "key_evidence": [
    "00:00 - 06:00 期间所有房间无人（Occupancy=0），但客厅温度仍持续上升。",
    "07:17 检测到人员离开家门，若因高温导致的不适或紧急避险，通常会有其他设备（如空调自动调节、窗户打开）的联动反应，但未见此类行为。",
    "温度变化速率过快且缺乏对应热源事件支持（如灶具使用记录缺失）。"
  ],
  "recommended_actions": [
    "立即检查客厅温度传感器的电池供电及物理连接，排除接触不良。",
    "将客厅温度传感器与已知正常的相邻房间温度传感器进行交叉比对，确认是否为单一设备故障。",
    "在维修或更换传感器前，暂时忽略该传感器的温度数据，以免触发错误的空调控制或火灾误报。"

## 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。

  "reasoning": [
    "1. 温度数据合理性分析：日志中的温度传感器数值（如2362, 2488等）符合Matter协议TemperatureMeasurement Cluster的编码格式（单位为0.01°C）。例如2362代表23.62°C，2488代表24.88°C。从凌晨到上午，室内温度随室外环境自然缓慢上升，且各房间温差合理（卧室约24°C，客厅/厨房因阳光照射略高），无突变或停滞，表明传感器工作正常。",
    "2. 人员活动模式分析：早晨06:17卧室有人起床并拉开窗帘，随后卫生间和厨房灯光开启，符合典型的晨间洗漱、准备早餐的行为逻辑。07:35左右入户门解锁并打开，随后门锁关闭，符合住户出门上班或外出的行为特征。",
    "3. 门窗与安防状态分析：09:10客厅窗户被打开（位置变为50%），接触传感器显示为False（未关），这通常是为了通风换气，属于正常生活行为。在此期间，虽然窗户打开，但并未触发入侵报警（因为是在家时间或已确认是住户操作，且后续有正常活动迹象）。入户门在住户离开后保持锁定状态，无异常反复尝试开锁记录。",
    "4. 传感器一致性检查：运动传感器（Occupancy）在无人时段（如深夜、白天大部分时间客厅无人时）显示为0，在人活动时段（早晨）显示为1，逻辑一致。没有发现传感器卡死（Stuck）或漂移（Drift）的迹象。"

    "行为链完整：06:17 卧室唤醒/开窗帘 -> 06:47 卫生间亮灯 -> 07:35 出门锁门，符合日常通勤逻辑。",
    "窗户开启为主动行为：09:10 客厅窗户打开，伴随温度轻微上升，属正常通风。"

    "推理步骤 3: 结合时间线，厨房温度在 08:00 后开始显著高于客厅，且波动较大，疑似灶具未关闭或电器故障导致持续加热。尽管 07:35 有人出门（门锁操作、门接触器变位），但室内温度并未因人员离开而下降，反而在白天持续累积热量，极有可能是火灾隐患（如忘记关火的灶具或故障电器）。"

## 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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或设备故障，日志显示为正常的家庭日常活动及洗衣机定时运行状态。",
  "reasoning": [
    "1. 分析重点设备（阳台洗衣机）：日志显示在 10:00 启动 (OperationalState=1)，随后在 10:20 和 10:40 出现 CountdownTime 递减事件（分别为 2400秒/40分钟 和 1200秒/20分钟），最后在 11:00 停止 (OperationalState=0)。这符合典型的洗衣机洗涤程序逻辑，无异常中断或卡死迹象。",
    "2. 分析入户门与玄关传感器：虽然日志中多次出现 entrance_occupancy = 1 且时间戳精确到 :39:21 或 :59:21 等固定偏移量，但这通常对应于住户进出家门时的正常行为模式（如开门、停留、关门）。结合 07:49 的 Manual Lock 操作，表明有人在家或刚回家，属于正常生活轨迹。",
    "3. 分析温度数据：各房间温度传感器数值在 2483-2557 (即 24.83°C - 25.57°C) 之间波动，变化平缓且符合夏季室内环境温度特征，未发现传感器漂移或故障导致的极端读数。",
    "4. 综合判断：所有设备状态变化均符合逻辑关联（如人进门-> occupancy 变1；洗衣机运行-> countdown 减少），未发现入侵、火灾、漏水或设备硬件故障的迹象。"
  ],
  "key_evidence": [
    "balcony_laundry_washer OperationalState 从 1 变为 0，中间伴随 CountdownTime 正常递减，证明设备完整执行了洗涤任务。",
    "entrance_occupancy 频繁触发但伴随 door_lock 手动操作及合理的居住者活动规律，排除非法入侵。",
    "全屋温度传感器读数稳定在舒适区间，无异常跳变。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控洗衣机后续周期的运行状态以确保长期稳定性。"
  ]
}
```

{
  "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。"
  ],
  "key_evidence": [
    "正常样本倒计时递减并停止；异常样本数值长时间固定。"
  ],
