## 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。",
  "reasoning": [

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到客厅和厨房温度异常升高，且伴随窗户开启但室内无人，存在严重的火灾风险或设备过热隐患。",
  "reasoning": [
    "推理步骤 1: 分析温度数据趋势。从凌晨 03:10 到上午 09:50，客厅 (living_room) 温度从约 23.7°C (2368/100) 持续上升至 25.6°C (2556/100)，厨房 (kitchen) 温度也从 24.8°C 上升至 25.6°C。虽然绝对值看似不高，但在无人员活动的情况下，这种持续且显著的升温速率（尤其是厨房区域）不符合自然散热规律，暗示有热源产生。",
    "推理步骤 2: 结合 occupancy 状态进行交叉验证。日志显示在温度急剧上升期间（07:15 - 09:50），客厅运动传感器 (living_room_occupancy) 多次报告为 0（无人）。这意味着高温并非由住户活动引起，而是环境本身的问题。",
    "推理步骤 3: 关联窗户状态与热力学逻辑。09:10 时客厅窗户被打开 (CurrentPositionLiftPercent100ths = 5000)，随后接触传感器变为 False（开启）。通常开窗会加速散热导致降温，但在此之后，厨房温度仍在高位徘徊甚至微升，且客厅温度并未出现预期的快速下降，这表明内部可能存在持续的热源（如灶具未关、电器故障或线路过热），或者窗户开启是试图缓解但未成功掩盖了核心问题。考虑到厨房温度长期维持在 25.5°C+ 且无人看管，极有可能是灶具 (cook_surface) 处于意外开启状态或发生了电气故障。",
    "推理步骤 4: 排除其他因素。卧室有人活动但温度正常波动，排除了全屋空调失效的可能性；入户门锁操作发生在 07:33，属于正常离家流程，非入侵迹象。综合来看，最合理的解释是厨房区域存在未察觉的火灾隐患。"
  ],
  "key_evidence": [
    "07:15 至 09:50 期间，living_room_temp_sensor 读数从 2515 升至 2556，kitchen_temp_sensor 读数从 2505 升至 2559，呈现持续上升趋势。",
    "在同一时间段内，living_room_occupancy 和 kitchen 相关日志中未检测到人员活动，表明高温为无人值守状态下的异常升温。",
    "09:10 客厅窗户开启后，室内温度未出现显著下降，反而维持高位，暗示存在持续内部热源。"
  ],
  "recommended_actions": [
    "立即通过 Matter 协议远程关闭厨房灶具 (cook_surface) 并切断厨房电源（如果安全允许）。",
    "检查厨房烟雾报警器 (smoke_co_alarm) 状态，确认是否已触发警报。",
    "通知住户回家后立即检查厨房是否有明火、焦糊味或异常发热的电器。",

## 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: ...",

    "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. 门锁与入户门状态一致且安全：07:23 左右，入户门传感器关闭 (False) 且门锁锁定 (LockState=1)，表明住户离家并正确锁门。后续玄关运动传感器多次触发 (Occupancy=1)，结合时间（早晨至中午），符合住户在家活动的正常模式，无非法入侵迹象。",
    "3. 温度数据合理：各房间温度传感器读数在 24.76°C 至 25.58°C 之间波动，变化趋势平缓，符合夏季室内环境温度特征，无传感器漂移或故障导致的极端数值。",
    "4.  occupancy 模式正常：主卧、客厅等区域的运动传感器数据显示住户在卧室休息或在客厅/玄关活动，符合常规作息规律，未发现长时间静止（可能跌倒）或异常夜间活动等健康风险。"
  ],
  "key_evidence": [
    "balcony_laundry_washer OperationalState 从 1 变为 0，中间有 CountdownTime 递减记录，证明设备完整执行了洗涤周期。",
    "front_door_lock LockState = 1 且 front_door_contact StateValue = False，确认离家上锁。",
    "entrance_occupancy 在 08:08-13:23 期间多次触发 Occupancy=1，符合居家活动特征。",
    "所有 temperature_sensor 读数均在舒适区间 (24-26°C)，无异常跳变。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控洗衣机运行状态，确保其按时结束工作以防漏水风险（虽然当前日志显示正常结束）。"
  ]
}
```

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",
  "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "洗衣机运行状态正常，符合典型的家庭洗衣流程（启动-倒计时结束-停止），未检测到安全威胁或设备故障。",
  "reasoning": [
    "1. 分析目标设备 'balcony_laundry_washer' 的状态变化：在 10:00:00 时，OperationalState 变为 1 (Running/Active)，表明洗衣机开始工作。",
    "2. 观察倒计时逻辑：10:20:00 时 CountdownTime 为 2400秒 (40分钟)，10:40:00 时 CountdownTime 为 1200秒 (20分钟)。这表明设备正在按预期进行倒计时，且时间流逝与倒计时减少量一致（20分钟内减少了20分钟的剩余时间），证明设备内部计时器工作正常。",
    "3. 确认任务完成：11:00:00 时，OperationalState 变为 0 (Idle/Stopped)，此时距离启动已过去60分钟。虽然中间显示的剩余时间是20分钟，但考虑到洗衣机可能包含脱水、烘干等阶段，或者日志采样间隔导致的显示差异，最终状态归零表明一个完整的洗涤周期已结束。",
    "4. 结合环境上下文：在此期间（10:00-11:00），家中其他区域（如主卧、儿童房）有人员活动迹象（Occupancy=1），且温度传感器读数在合理范围内波动，没有火灾、漏水或入侵的迹象。"

## 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。"
  ],

  "threat_description": "卧室温度传感器在夜间出现严重的数据跳变和逻辑矛盾，显示设备可能故障或受到干扰。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-08-24T17:00:00 时，卧室温度传感器报告数值为 2580 (约 25.8°C)，而仅 5 分钟后 (17:05:00) 骤降至 2266 (约 22.66°C)。这种在短时间内发生超过 3 度的剧烈下降不符合正常热惯性规律。",
    "推理步骤 2: 对比同一时间段的其他数据，客厅温度在同一时刻从 2520 平稳过渡到 2349，厨房温度也保持平稳下降趋势，说明环境温度整体是稳定下降的（可能是空调开启或室外降温），排除了环境突变导致的可能性。",
    "推理步骤 3: 结合 occupancy_sensor 日志，17:00 后卧室无人活动，且后续温度持续缓慢下降至 2141°C (约 21.4°C)，符合夜间自然散热特征。唯独 17:00 的那个 2580 读数是一个孤立的异常峰值，极大概率是传感器硬件故障、通信丢包导致的错误上报或校准失效。"
  ],
  "key_evidence": [
    "2026-08-24T17:00:00 bedroom_temp_sensor 报告 2580，随后 5 分钟内骤降至 2266，温差变化 >3 度且无合理物理原因。",
    "同期客厅和厨房温度传感器数据显示正常的线性下降趋势，证明环境背景正常，异常仅存在于卧室传感器。",
    "该异常读数发生在住户回家前（门锁操作在 18:06），若传感器真实反映高温，可能导致空调误判或用户进入时感到不适，属于潜在的设备健康隐患。"
  ],
  "recommended_actions": [
    "立即检查卧室温度传感器的电池电量及连接状态，排除供电不稳导致的读数错误。",
    "尝试重置卧室温度传感器，并重新校准其基准温度。",
    "在维修期间，建议暂时依赖客厅温度传感器作为卧室温度的参考值，或手动设置恒温器以保障舒适度。"

## 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 1: 分析时间线发现，从 14:00 到 16:59，客厅温度（living_room_temp_sensor）呈现持续且合理的下降趋势（从 2461 降至 2362），符合独居老人家中无人活动时的自然散热规律。",
    "推理步骤 2: 在 17:00:00 这一时刻，日志中同时出现了两条记录：一条显示温度骤升至 2520，另一条显示卧室温度也异常飙升至 2580。这种瞬间的剧烈升温与前一小时的降温趋势完全相反，且数值极高（约 25.2°C - 25.8°C，假设单位是 mK 则约为 25.2-25.8°C，若为原始值则远超正常室温范围，结合上下文推测为异常高值）。",
    "推理步骤 3: 随后在 17:15:00，温度又瞬间回落到 2356，并在之后继续缓慢下降。这种“骤升 - 骤降”的非物理性波动模式，排除了环境温度突变的可能性，极大概率是传感器硬件故障、通信丢包导致的乱码，或者是被恶意攻击篡改了数据。",
    "推理步骤 4: 考虑到住户为独居老人，如果该传感器用于联动空调或烟雾报警系统，其故障可能导致无法正确判断室内环境，存在安全隐患（如误报或漏报）。"

    "2026-07-19T17:15:00 时刻上述两个传感器的读数又分别瞬间回落至 2356 和 2244，显示出明显的非连续性数据跳变。",
    "此前 14:00-16:59 期间数据平稳下降，与 17:00 的突变形成强烈对比，不符合自然热力学规律。"

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。"

  "threat_description": "厨房温度传感器在正常监测期间出现数据丢失（None），且整体家庭温度读数异常偏高，疑似传感器故障或环境极端异常。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-07-01T07:25:00 时厨房温度传感器报告了有效值 (2519)，但在随后的 2026-07-01T07:26:00 立即报告为 None，随后又恢复数值。这种瞬间的数据中断（Data Gap）是典型的传感器通信故障、电源波动或硬件死机特征。",
    "推理步骤 2: 检查温度数值的合理性。日志中显示的温度值（如 2401, 2556 等）明显高于标准摄氏度单位（通常范围 -20 到 60）。虽然 Matter 协议允许自定义单位，但结合多个房间（客厅、主卧、儿童房、厨房）同时出现 23-25 度以上的读数，且数值随时间线性缓慢上升，这不符合自然昼夜温差变化规律（夜间应降温，清晨应回升但不会持续攀升至 25+ 度而不触发空调或报警）。这表明传感器可能发生了严重的读数漂移（Drift）或校准错误。",
    "推理步骤 3: 综合判断。单一传感器的瞬时掉线（None）加上多房间传感器长期存在的非物理合理的高数值漂移，强烈指向传感器硬件故障或固件逻辑错误，而非真实的环境高温威胁。若为真实火灾风险，烟雾报警器应在如此高的‘温度’下早已触发，但其状态未变，进一步佐证了这是传感器数据层面的问题。"
