## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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: 正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "key_evidence": [
    "正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],

    "继续监测，无需立即处置。"
  ]
}

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在灶具开启后出现严重数据漂移，读数瞬间异常飙升（2532 -> 2920），随后迅速回落，疑似传感器故障或受到强电磁干扰导致误报。",
  "reasoning": [
    "推理步骤 1: 分析时间线，2026-07-02T12:05:00 厨房灶具 (kitchen_cook_surface) 状态变为 True (开启)，此时厨房温度传感器读数为 2528 (约 25.28°C)，符合正常烹饪升温逻辑。",
    "推理步骤 2: 在 T12:12:00，即灶具开启仅 7 分钟后，厨房温度传感器读数突然跳变至 2920 (约 29.20°C)。虽然数值上升，但考虑到从 25.28 到 29.20 的温差对于短时间烹饪是合理的，需结合后续数据判断。",
    "推理步骤 3: 关键异常点在于 T12:12:00 的读数 2920 与前后时刻数据的剧烈不一致性。前一刻 (T12:05) 为 2528，下一刻 (T12:15) 骤降至 2532。如果真实温度真的达到了 29.2°C，通常不会在 3 分钟内自然回落到 25.3°C，除非环境温度极低且无热源，但这与‘灶具开启’矛盾。更可能的情况是传感器发生了瞬时故障、通信丢包导致的乱码，或是受到了强烈的电磁干扰（如大功率电器启动）导致读数畸变。",
    "推理步骤 4: 对比其他房间传感器，同一时间段内主卧、次卧和客厅的温度变化平稳且符合人体活动规律，排除了全屋系统性温度异常的可能性，进一步证实厨房传感器存在独立的问题。"
  ],
  "key_evidence": [

    "2026-07-02T12:15:00 厨房温度：2532 (迅速回落)",
    "同一时段其他房间温度传感器数据稳定，无类似波动"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的物理连接及供电情况，排除接触不良。",
    "检查厨房是否有强电磁干扰源（如微波炉、大功率电机同时运行），尝试隔离测试。",
    "建议更换该温度传感器或校准设备，以确保火灾预警系统的可靠性。",
    "在修复前，建议人工定期巡检厨房温度，防止因传感器失效导致的高温隐患未被发现。"

## 任务
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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。

    "2. 排除火灾风险：尽管厨房灶具（cook_surface）在早晨 06:03 开启并在 06:34 关闭，但在此期间烟雾报警器未触发报警（TestInProgress 为 False 或无相关报警状态）。温度传感器读数稳定在 24-25°C 左右（Matter协议中通常单位为0.01摄氏度，即24.84°C），未见异常高温飙升，符合正常烹饪后的散热过程。",
    "3. 确认人员活动正常：日志显示住户在早晨 06:03 进入厨房并开灯、使用灶具，随后在 07:00 后陆续出现在卧室、玄关和客厅。这种作息模式符合独居老人的正常生活规律（早起做饭、起床活动），不存在长时间静止不动导致的跌倒或健康风险（abnormal_inactivity/possible_fall）。"

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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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": [

    "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

  "reasoning": [
    "1. 烹饪行为分析：12:01 厨房灯和灶具开启，持续至 12:44 关闭，时长约 43 分钟，符合正常午餐准备习惯。期间温度传感器读数随加热上升（2587 -> 2921），随后自然回落，无过热报警或烟雾触发，表明烹饪过程受控且无人遗忘关火。",
    "2. 洗碗机状态分析：14:00 洗碗机进入工作状态（OperationalState=1），14:30 设置倒计时 1800 秒（30分钟），14:55 结束工作（OperationalState=0）。整个流程逻辑连贯，符合标准洗涤周期，无异常中断或卡死现象。",
    "3. 环境与人员活动一致性：客厅和卧室的运动传感器在下午时段（13:02-15:03）频繁触发 Occupancy=1，与厨房和客厅的温度波动趋势一致，表明住户在家中正常活动。卫生间传感器间歇性归零（Occupancy=0）也符合如厕等短暂停留的行为特征。",
    "4. 设备数据合理性：温度传感器数值（如 2587 代表 25.87°C）变化平滑，无突变或停滞；门窗传感器仅在烹饪结束后短暂记录一次关闭状态，未见非法入侵迹象（如门锁异常操作或窗户长时间未关）。"
  ],

    "living_room_occupancy 和 bedroom_occupancy 在 13:00-15:00 期间多次检测到人，证实住户在家，排除了离家状态下设备误报的可能性。"
  ],

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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: 正常余热会逐步回落；异常样本在关火后温度继续上升。"
  ],
  "key_evidence": [
    "正常余热会逐步回落；异常样本在关火后温度继续上升。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在烹饪活动期间出现严重数据漂移和异常跳变，导致无法准确监测火灾隐患。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，2026-08-10T19:00:00 至 19:20:00 期间，厨房灶具 (kitchen_cook_surface) 处于开启状态，且厨房运动传感器显示有人在场，符合正常的烹饪场景。",
    "推理步骤 2: 在此正常烹饪期间，厨房温度传感器 (kitchen_temp_sensor) 的读数从约 22°C (2275 mK) 缓慢上升至 23°C 左右 (2304 mK)，随后在 19:25:00 突然跳变为 28.6°C (2860 mK)，并在 19:35:00 再次跳变为 27.4°C (2740 mK)。这种在高温环境下的剧烈非物理性波动不符合热力学规律，表明传感器硬件故障或通信干扰。",
    "推理步骤 3: 考虑到独居老人家庭的安全脆弱性，如果依赖该传感器进行火灾预警（如联动烟雾报警器或自动关闭燃气），其失效将导致严重的“未受监控的烹饪”风险，可能引发火灾而无人察觉。尽管有烟雾报警器，但温度传感器的失效破坏了多模态安全冗余。"
  ],
  "key_evidence": [
    "事件：[2026-08-10T19:25:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2860 (对应 28.6°C)",
    "事件：[2026-08-10T19:35:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2740 (对应 27.4°C)",
    "上下文：同一时间段内灶具开启且有人在场，温度应平稳上升而非剧烈震荡。"
  ],
  "recommended_actions": [
    "立即检查并更换厨房温度传感器，确认其硬件是否损坏或连接不稳定。",
    "在设备维修前，暂时手动启用厨房烟雾报警器的独立测试模式，确保其功能正常作为临时备份。",
    "通知住户近期避免长时间独自进行高温烹饪，或由家属协助监督。"
  ]
}

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。

    "结论修正：基于对数据单位的正确解读（0.01°C 缩放），厨房温度完全正常；烟雾报警器自检成功且无污染；无人员在场导致误报风险低。因此，判定为无异常。"

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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，日志显示为正常的早晨起床、离家及烟雾报警器自检流程。",
  "reasoning": [
    "1. **人员活动模式分析**：07:02 卫生间有人（Occupancy=1），随后在 07:15-07:22 期间厨房灯开启又关闭，卧室灯关闭，符合用户起床洗漱后短暂进入厨房或整理仪容的行为。07:22 门锁手动上锁并关门，表明住户正常离家上班或外出，行为逻辑连贯且合理。",
    "2. **设备状态分析**：08:00 至 08:05 期间，厨房烟雾报警器触发 `TestInProgress = True` 并在 5 分钟后恢复为 `False`，同时污染状态为 0。这是典型的定期自检或手动测试行为，并非火灾报警（Fire Alarm）或一氧化碳泄漏报警。在此期间，温度传感器读数平稳上升（从 ~25.1°C 升至 ~25.3°C），无剧烈波动，佐证了没有发生燃烧事件。",
    "3. **环境数据一致性**：全天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。客厅和卧室的运动传感器在住户离家后保持无人状态（Occupancy=0），与门锁离家的时间线一致，未发现异常入侵迹象。"
