## 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": [
    "推理步骤 1: 在 2026-08-08T13:00:00 时，系统记录到客厅空调 (living_room_ac) 被开启 (OnOff.OnOff = True)。",
    "推理步骤 2: 随后在 2026-08-08T13:15:00，同一房间的温度传感器报告数值为 2840。考虑到 Matter 协议中温度通常以 0.01°C 为单位，该值换算为 28.40°C。虽然高温可能，但结合上下文需进一步验证。",
    "推理步骤 3: 关键异常出现在 2026-08-08T13:35:00，传感器再次报告数值 2720 (即 27.20°C)，而在 13:20:00 时数值已回落至 24.88°C。更严重的异常发生在 13:55:00，数值突然飙升至 2610 (26.10°C)，随后在 14:00:00 又骤降至 24.64°C。",
    "推理步骤 4: 这种在短时间内（几分钟内）反复出现的剧烈波动（从 ~24.9°C 跳到 ~27.2°C 再跳回），且与空调运行状态无合理的物理热惯性对应关系，强烈表明传感器读数不稳定、校准失效或通信数据包损坏，属于典型的传感器故障 (sensor_malfunction)，而非真实的环境温度变化。",
    "推理步骤 5: 对于独居老人家庭，错误的温度数据可能导致空调控制逻辑失效（如过热未制冷或过度制冷），进而引发健康隐患或能源浪费，因此判定为高置信度的异常。"

    "2026-08-08T13:35:00 温度读数再次异常升高至 2720 (27.20°C)，随后迅速回落。",
    "2026-08-08T13:55:00 温度读数再次异常波动至 2610 (26.10°C)，显示数据极度不稳定。"
  ],
  "recommended_actions": [
    "立即检查并重启客厅温度传感器设备，尝试恢复其正常通信。",

## 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_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. 重点设备（阳台洗衣机）状态分析：日志显示洗衣机在 10:00 启动 (OperationalState=1)，随后在 10:20 和 10:40 分别报告倒计时剩余 2400秒和 1200秒，最后在 11:00 停止 (OperationalState=0)。这符合标准洗衣程序（约40分钟）的运行逻辑，无异常中断或卡死现象。",
    "2. 入侵与人员活动分析：入户门传感器在 07:40 短暂开启后关闭，且门锁状态正常。玄关运动传感器在 07:50 至 12:40 期间持续检测到人 (Occupancy=1)，这与早晨起床、洗漱、准备出门或在家活动的正常行为模式一致。其他房间（客厅、卧室）的运动传感器在夜间/清晨大部分时间为0，符合住户尚未完全活跃或处于休息状态的特征。",
    "3. 环境与安全指标分析：所有温度传感器读数在 25°C - 26°C 之间波动，属于舒适的室内环境温度范围，无剧烈跳变或极端值，排除火灾或设备过热风险。未检测到烟雾、漏水或一氧化碳报警信号。"
  ],
  "key_evidence": [
    "balcony_laundry_washer OperationalState 从 1 变为 0，中间伴随 CountdownTime 递减 (2400->1200)，表明程序正常结束。",
    "entrance_occupancy 在 07:50-12:40 期间保持为 1，符合早晨居家活动规律。",
    "front_door_lock 仅在 07:40 出现一次解锁/开门动作，随后恢复常态，无多次非法尝试。",
    "各房间温度传感器数值稳定在 2500-2550 (25.0-25.5°C) 范围内，无异常高温。"
  ],
  "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，确保其长期稳定性。"
  ]
}
```

{
  "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。"
  ],
  "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
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": "设备工作状态正常，日志显示为典型的晚间回家、烹饪及休息前的日常行为模式，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. **入户与活动轨迹分析**：18:06 门锁手动解锁（Manual），随后客厅 occupancy 传感器检测到有人（Occupancy=1），且空调开启。这符合用户下班回家的典型行为逻辑，无非法入侵迹象。",
    "2. **烹饪行为分析**：18:54 灶具开启，19:29 厨房窗户打开（可能是为了通风排烟），随后温度传感器读数在烹饪期间有波动但随后趋于稳定。整个过程伴随人员活动（客厅 occupancy 持续为 1），属于正常的无人值守风险较低的场景（人在家附近）。",
    "3. **卧室灯光异常解释**：虽然任务重点提及 bedroom_light，但在 20:10 该灯亮起并调光至 180，随后在 20:18 调暗至 30。结合此时段卧室 occupancy 为 0（可能因传感器盲区或人刚离开/未进入检测区），以及客厅仍有人员活动，这更可能是用户在睡前准备阶段调整卧室氛围灯，或者是自动化场景触发，而非故障。即使无人，短时间开灯后调暗也是常见操作，不构成 'sensor_stuck' 或 'actuator_stuck' 的长期故障特征。",
    "4. **传感器数据合理性**：各房间温度传感器读数随时间缓慢变化，符合物理规律（如夜间散热、烹饪加热等），未见跳变或停滞导致的 'sensor_drift' 或 'sensor_malfunction'。"

    "推理步骤 3: 结合时间线，用户在 18:06 回家，18:10 开启空调，18:54 开启灶具。虽然开启了空调，但厨房区域温度并未如预期般快速下降至舒适范围，反而在灶具开启后出现持续的高温读数，且 19:29 厨房窗户接触传感器显示为 False (关闭)，导致热量无法通过自然通风排出，增加了热积聚和火灾风险的可能性。",
    "推理步骤 4: 尽管有洗碗机在 20:10 开启，但这通常不会导致如此高的温度读数，主要热源仍指向灶具。温度的持续高位和缺乏有效降温措施构成了明确的火灾隐患。"

## 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",
    "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: 从 11:02 到 11:40（约 38 分钟内），厨房温度从 2539 (°C*100) 持续上升至 2549 (°C*100)，即 25.39°C 升至 25.49°C。虽然绝对温差不大，但结合独居老人背景，需关注设备状态。",
    "推理步骤 3: 关键异常点在于 2026-07-05T11:35:00，厨房温度传感器报告值为 None（数据丢失/通信中断）。在烹饪过程中传感器突然失效或停止上报，可能导致烟雾报警器无法联动或用户失去对高温环境的感知，构成安全隐患。此外，日志中未出现任何关闭灶具的操作记录，若烹饪结束未及时关闭，长期加热也可能导致过热。",
    "推理步骤 4: 考虑到住户为独居老人，对突发状况反应可能较慢，传感器数据丢失 (None) 意味着安全监控链路的断裂，属于高风险事件。"

    "在 09:10 时，living_room_window_contact 显示为 False (打开)，但 living_room_window 窗帘仅开启 50%，未能形成有效的对流散热通道，加剧了室内积热风险。",

## 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 OnOff 和亮度值一致变化；异常样本存在持续矛盾状态。"
  ],
  "key_evidence": [
    "正常样本 OnOff 和亮度值一致变化；异常样本存在持续矛盾状态。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

{
  "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 OnOff 和亮度值一致变化；异常样本存在持续矛盾状态。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}
