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",

    "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",

  ],
  "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。"

{
  "is_anomaly": true,

  "threat_description": "卧室温度传感器在 14:05:00 出现严重数据跳变，从 2365 (mK) 瞬间变为 2550 (mK)，随后又回落至正常范围，表明传感器存在硬件故障或通信干扰。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 bedroom_temp_sensor 在 2026-07-01T14:05:00 报告了两个连续的温度值：前一个为 2365 mK (约 23.65°C)，后一个为 2550 mK (约 25.50°C)。",
    "推理步骤 2: 虽然温差看似不大，但结合上下文观察，该传感器在 14:00 之前和之后均呈现缓慢下降趋势（符合独居老人可能离开卧室或空调关闭后的自然降温规律），而 14:05:00 的读数突然异常升高，打破了这一平滑的物理变化模式。",
    "推理步骤 3: 考虑到这是针对独居老人的安全监控，传感器的瞬时剧烈跳变极可能是由于设备内部电路不稳定、电池电压波动或无线信号干扰导致的误报。这种‘毛刺’数据若被系统直接用于触发警报（如误判为室温过高开启空调或反之），将严重影响对老人真实环境状态的判断，属于典型的传感器 malfunction。"

## 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。

{
  "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: 正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "key_evidence": [
    "正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数出现严重漂移，数值异常偏高且波动剧烈，远超正常环境温度范围，可能导致空调控制失效或误报高温。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 09:00 到 17:00，living_room_temp_sensor 的 MeasuredValue 持续在 2530-2560 之间波动（对应约 25.3°C - 25.6°C），虽然看似在高温，但结合后续数据看趋势异常。",
    "推理步骤 2: 关键异常点出现在 17:00:00，该传感器读数瞬间跳变至 2520 (25.2°C)，随后在 17:15 和 18:50 等时间点，卧室温度传感器读数也出现类似的高位波动（如 2580, 2208 等，需注意单位换算，Matter 常用毫开尔文 mK，2500mK=25°C，但此处数值变化幅度极大）。更明显的异常是：在 17:00 时，三个房间的温度传感器同时报告了极高的数值（Living Room: 2520, Bedroom: 2580），而厨房温度在同一时间仅为 2365 (23.65°C)。",
    "推理步骤 3: 考虑到独居老人的居住环境，夏季室内温度通常不会达到 25°C+ 并维持如此长时间的稳定高位（除非极端天气，但厨房温度较低形成反差）。更重要的是，观察 15:00 时的数据，Living Room 为 2410/2420，Bedroom 为 2420；到了 17:00 突然全部飙升。这种跨设备、非同步的剧烈跳变不符合物理热力学规律（热量传递需要时间），极大概率是传感器校准丢失、固件 Bug 导致的数值漂移（Drift）或硬件故障，而非真实环境温度变化。",
    "推理步骤 4: 此外，日志中未见烟雾报警器触发，也未见漏水报警，排除了火灾和漏水风险。主要问题集中在温度传感器的数据可信度上。"
  ],
  "key_evidence": [
    "2026-07-01T17:00:00 时刻，客厅、卧室温度传感器读数同时异常升高（Living Room: 2520, Bedroom: 2580），而同期厨房温度为 2365，温差逻辑不合理。",
    "温度读数在短时间内（如 15:00 到 17:00）出现无规律的剧烈跳变，不符合自然热环境变化曲线。",
    "作为对比，同一时间段内 occupancy 和 kitchen_temp 数据相对平稳，突显了温度传感器的特异性故障。"
  ],
  "recommended_actions": [
    "立即检查客厅和卧室温度传感器的物理状态，确认是否被遮挡、损坏或电池电量不足。",
    "联系 Matter 设备厂商或技术支持，请求重置传感器校准或更换故障设备。",
    "在修复前，建议老人手动监测室温，避免完全依赖自动温控系统，以防过热或过冷。"

## 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。

```json

    "2. 环境传感器数据合理性：客厅温度传感器数值从 2466 (24.66°C) 逐渐下降至约 2244 (22.44°C)，呈现随时间推移的自然降温趋势（可能因空调运行或室外温度降低），数值变化平滑且符合物理规律，无跳变或停滞现象，排除传感器卡死或漂移。",
    "3. 人员活动与设备联动一致性：日志显示多个房间（儿童房、主卧、餐厅、玄关）的运动传感器在傍晚至夜间时段频繁检测到人（Occupancy=1），这与客厅灯光的使用时间窗口高度重合。例如，17:51 门锁手动操作后不久客厅开灯，18:06 客厅检测到有人，表明家庭成员正常回家并活动，不存在入侵或长时间无人却误触发的情况。",
    "4. 其他设备状态正常：洗碗机在 19:31 开启，符合晚餐后清洁习惯；主卧窗帘在 22:14 关闭，符合就寝前的常规操作。未发现烟雾报警、漏水或门锁异常等危险信号。"
  ],
  "key_evidence": [

    "多房间 occupancy_sensor 持续报告有人活动，与灯光和设备使用行为一致。",
    "master_bedroom_window 在 22:14 关闭，符合夜间就寝流程。"
  ],
  "recommended_actions": [

## 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

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 4: 虽然厨房窗户传感器在 18:36:30 关闭（False），但这属于正常操作；真正的异常在于关键安全/环境监测设备（温度传感器）的不可用性，可能导致无法准确监测潜在的过热或火灾风险。"

## 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",

    "3. **门锁与安全状态**：07:05 入户门锁执行了手动解锁操作（LockOperationType=0, Manual），随后 08:20 再次显示锁定状态（LockState=2）。这表明老人可能出门散步或处理事务后返回并重新锁门，或者仅仅是检查门锁状态。整个过程中没有非法入侵迹象，门锁功能正常。",
    "4. **环境数据一致性**：各房间温度传感器读数变化平缓，符合夏季早晨气温逐渐升高的自然规律，未发现传感器漂移或故障。 occupancy 传感器在人员移动时正确响应，无卡死现象。"

## 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。

{
  "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。"
  ],
  "recommended_actions": [

  ]
}

  "threat_type": "fire_risk",
  "threat_description": "检测到厨房温度异常升高且伴随窗户开启，存在严重的火灾风险或设备过热隐患。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，从 07:10 开始，厨房温度传感器读数急剧上升，从 2523 (约 22°C) 持续攀升至 10:40 的 2544 (约 22.1°C)，虽然数值本身看似正常（Matter 协议中摄氏度通常需除以 10），但相对于凌晨 01:00 的 2290 (22.9°C)，全天呈现非自然的缓慢爬升趋势，且峰值出现在上午时段。",
    "推理步骤 2: 关键异常点在于 07:10:30 厨房窗户接触传感器状态变为 False (Open)。在家庭无人或仅有少量人员活动（如主卧有人）的情况下，厨房窗户无故打开通常意味着通风异常或外部入侵尝试，结合高温读数，极有可能是外部热源进入或内部设备故障导致热量积聚无法散发。",
    "推理步骤 3: 对比其他房间，次卧和主卧温度也同步出现上升趋势（从 24xx 升至 25xx），表明整个房屋环境温度正在累积升高。考虑到厨房是火灾高发区，且烟雾报警器日志未提及触发（可能尚未达到阈值或传感器未覆盖该特定热点），这种‘高温 + 开窗’的组合模式高度符合早期火灾特征或严重电气/燃气泄漏导致的过热风险。",
    "推理步骤 4: 尽管入户门在 07:19 被解锁并随后有人进入（entrance_occupancy=1），但这发生在高温持续上升之后，不能解释为何厨房会在无人长时间停留期间温度异常升高。最合理的推断是厨房内部发生了不可见的燃烧过程或设备故障，导致温度异常。"

    "全房多区域温度同步缓慢爬升，显示环境热积累异常。"

  "recommended_actions": [
    "立即通知住户前往厨房检查是否有明火、烟雾或异味。",
    "建议手动关闭厨房窗户以阻断可能的外部气流干扰，并检查灶具及电器是否处于异常工作状态。",
