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
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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",

  ],

}
```

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: 检查洗碗机状态日志，显示其在 14:00 开始运行 (OperationalState=1)，并在 15:00 和 17:05 报告倒计时时间 (CountdownTime)，表明设备正在按计划执行清洗程序，属于正常的自动化行为。",
    "推理步骤 3: 结合住户习惯，日志中多个房间（卫生间、客厅、卧室）的运动传感器均报告为 '0' (无人)，且时间为下午时段，符合住户外出或不在家的场景。在此场景下，厨房温度因电器关闭而下降是预期内的正常现象，不存在未受监控烹饪导致的过热风险。"

  "key_evidence": [
    "kitchen_temp_sensor 数据显示温度呈线性下降趋势 (2509 -> 2353)，而非异常升高。",
    "kitchen_dishwasher 记录了明确的运行状态变更和倒计时更新，证明设备处于正常工作流程中。",
    "多房间 occupancy_sensor 同时报告 '0'，确认了家庭环境处于低活动状态，排除了有人在内操作灶具的可能性。"
  ],
  "recommended_actions": [

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。

监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

请按以下 JSON 格式回答：

  "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",

请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "safety_device_failure",
  "threat_description": "厨房烟雾报警器连续两天报告污染状态（ContaminationState）并逐渐恶化，表明设备可能因灰尘积累或故障导致误报风险增加或功能失效。",

    "2. 分析状态含义：在Matter协议及常见智能家居标准中，ContaminationState通常用于指示传感器探测窗口的清洁程度。值从1增加到3表示污染程度加剧（例如：1=轻微/注意，2=中度/需清洁，3=严重/需维护或已失效）。",
    "3. 排除其他干扰因素：虽然同一时间段内厨房温度传感器读数有波动（25°C左右），但这是正常的室温范围，且没有伴随火灾报警（FireAlarm）或一氧化碳报警（COAlarm）触发。门锁和运动传感器的活动显示住户正常起居，无入侵迹象。",
    "4. 确定威胁类型：这种持续恶化的“污染”状态并非外部攻击或火灾，而是安全设备本身的健康状况问题。如果不清理或更换，可能导致未来真实火灾时无法正确报警，或频繁产生误报，属于安全设备故障/维护需求。"

    "推理步骤 2: 关联烟雾报警器日志，观察到在温度升高的同时，SmokeCoAlarm.ContaminationState 数值从 1 逐渐增加到 2，最终达到 3。根据 Matter 协议及常见安全逻辑，该数值的递增通常代表污染程度加剧或报警级别提升（例如：1=轻微/测试，2=警告，3=严重/确认火情）。",
    "推理步骤 3: 结合住户行为日志，虽然入户门有正常的开关记录，但厨房内并未检测到明显的烹饪活动（如灶具开启事件），且高温持续时间较长，排除了短暂烹饪导致的可能性，更符合电器故障、线路短路或无人看管下的持续燃烧迹象，构成了明确的火灾威胁。"

## 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: ..."
  ],

    "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": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房烟雾报警器触发，且室内温度呈现异常持续上升趋势，存在真实火灾或过热风险。",
  "reasoning": [
    "1. 关键告警触发：日志显示在 03:16:00，厨房烟雾报警器（kitchen_smoke_alarm）的 SmokeState 变为 1（报警状态），同时客厅烟雾报警器因互联机制（InterconnectSmokeAlarm）也变为 1，表明系统检测到烟雾。",
    "2. 伴随温度异常升高：在烟雾报警前后，厨房和客厅的温度传感器读数呈现持续、显著的上升趋势。例如，厨房温度从 02:55 的 23.69°C 上升至 04:00 的 24.09°C，随后继续攀升至 05:15 的 24.52°C（注：Matter协议温度单位为0.01°C，故2369代表23.69°C）。虽然绝对值未达极高，但在深夜无人活动时段（所有Occupancy均为0），这种非环境自然波动导致的持续升温结合烟雾报警，高度指向热源失控。",
    "3. 排除误报与正常行为：此时段（凌晨3-5点）所有房间运动传感器均显示无人员活动（Occupancy=0），排除了老人因身体不适导致设备误触或忘记关闭灶具后离开现场的可能性（因为人不在家/房）。独居老人在深夜发生火灾风险极高，且无法自救。"

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。

    "2. 排除真实威胁：在触发 ContaminationState 的时间点前后，厨房温度传感器读数稳定在 25°C 左右（如 2540 mK = 25.4°C），没有急剧升温；同时，虽然厨房运动传感器有活动记录，但未见灶具长时间无人看管或高温报警等典型火灾前兆。因此，这并非真实的火灾风险。",
    "3. 确定威胁类型：ContaminationState 通常指示传感器内部积尘、老化或电子元件故障。对于独居老人家庭，烟雾报警器是关键的早期预警设备。如果设备处于“故障/污染”状态，一旦发生火灾，它可能无法正常工作，构成严重的安全隐患（Safety Device Failure）。"

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。

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。

    "1. 观察关键设备 'kitchen_smoke_alarm' 的状态变化：7月14日08:00报告 ContaminationState=1，7月15日08:00报告 ContaminationState=2，7月16日08:00报告 ContaminationState=3。这表明污染/故障等级在逐日递增。",
    "2. 排除真实威胁：日志中显示灶具（cook_surface）仅在7月14日07:09开启并在07:26关闭，7月15日07:26关闭（未显示开启记录，或已提前关闭），且温度传感器读数正常（25-26°C左右），没有急剧升温或高温报警，说明不存在未看管烹饪导致的烟雾积聚。",
    "3. 分析行为模式：污染状态的报告时间非常规律（均为早上08:00整），这与住户起床后的活动节奏（如进入厨房、开窗等）可能有关，但更可能是设备自检周期或定时上报机制触发了对内部灰尘/老化的检测。",
    "4. 综合判断：Matter协议中的 SmokeCoAlarm.ContaminationState 通常用于指示传感器需要清洁或存在故障。数值从1升至3表示情况恶化，而非环境烟雾浓度（那是 AlarmState）。因此，这是典型的传感器维护需求或硬件故障，属于安全设备本身的异常，而非外部入侵或火灾风险。"

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。
