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",
  "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": "未检测到安全威胁或设备故障，日志显示为正常的家庭环境监控及洗衣机定时任务执行过程。",
  "reasoning": [
    "1. 分析重点设备（阳台洗衣机）状态：日志显示在 10:00 时 OperationalState 变为 1（运行中），随后在 10:20 和 10:40 分别报告 CountdownTime 为 2400秒和 1200秒，最后在 11:00 变为 0（完成/空闲）。这符合典型的洗衣机洗涤程序逻辑（剩余时间递减直至结束），属于正常行为。",
    "2. 分析传感器数据一致性：所有温度传感器读数在 2471-2559 (即 24.7°C - 25.6°C) 之间波动，变化幅度小且符合室内环境温度随时间缓慢变化的规律，无突变或停滞现象，排除 sensor_stuck 或 sensor_drift。",
    "3. 分析人员活动模式：多个房间的运动传感器（occupancy_sensor）持续报告 Occupancy = 0，表明房屋内无人活动。结合洗衣机自动运行的情况，推测住户可能外出或处于非活跃状态，但这本身不构成安全威胁（如入侵或跌倒），除非有异常的时间段报警，但当前日志仅展示静态的无人状态，无矛盾点。",
    "4. 综合判断：没有发现门锁异常、漏水、烟雾报警、烹饪未关火等高风险事件，设备运行逻辑自洽，故判定为正常。"
  ],
  "key_evidence": [
    "balcony_laundry_washer OperationalState 从 1 变为 0，中间伴随 CountdownTime 从 2400 降至 1200，符合洗衣流程。",
    "所有 temperature_sensor 读数在合理范围内平稳波动，无异常跳变。",
    "多处 occupancy_sensor 持续为 0，与洗衣机无人值守运行的场景一致，无冲突。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议定期检查洗衣机滤网以确保长期运行效率（常规维护）。"
  ]
}
```

{
  "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。"

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",
  "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: 正常样本空调开启后温度逐步下降；异常样本持续不降反升。"
  ],
  "key_evidence": [
    "正常样本空调开启后温度逐步下降；异常样本持续不降反升。"

  "reasoning": [
    "推理步骤 1: 在 2026-07-31T13:00:00 时，系统检测到客厅空调 (living_room_ac) 被开启 (OnOff.OnOff = True)，随后在 13:05:00 温度读数正常下降至 2495 (单位应为 0.1°C，即 24.95°C)。",
    "推理步骤 2: 然而，在 13:15:00 空调运行约 15 分钟后，同一传感器的读数突然异常飙升至 2840 (即 28.40°C)，这与空调制冷导致的降温趋势完全相反，且数值远超合理波动范围。",
    "推理步骤 3: 紧接着在 13:35:00，该传感器再次报告 2720 (27.20°C)，随后在 13:55:00 又跳变为 2610 (26.10°C)。这种在短时间内反复出现的剧烈、非物理规律的数值跳变（Drift/Jump），排除了环境温度自然变化的可能性，强烈指向传感器硬件故障、通信干扰或固件逻辑错误。",
    "推理步骤 4: 对比其他房间的温度传感器（如主卧、儿童房、厨房），其数据变化平滑且符合室温自然波动规律，进一步证实问题仅局限于客厅温度传感器这一单一设备。"

  "recommended_actions": [
    "立即检查并重新校准客厅温度传感器，或将其暂时移除以排除其对自动化场景（如温控器）的误导影响。",
    "联系设备制造商进行固件更新或硬件维修/更换，因为数据显示为典型的传感器内部故障特征。",
    "在修复前，建议手动监控客厅实际温度，以防因误报高温导致不必要的空调频繁启停或低温误判引发舒适度问题。"

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。

{
  "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: 正常样本是小幅波动；异常样本出现不可能的极端跳变。"
  ],
  "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,
  "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": [
    "正常样本是小幅波动；异常样本出现不可能的极端跳变。"
  ],
  "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
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

  "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。

  "reasoning": [
    "推理步骤 1: 分析时间线发现，从 19:05 开始，厨房温度传感器读数急剧上升，从正常的 2431 (约 24.3°C) 飙升至 2677 (约 26.7°C)，并在随后几小时内维持在 2500-2600+ 的区间。",
    "推理步骤 2: 结合上下文环境判断，此时段厨房内有人员活动（occupancy=1），但并未开启灶具（cook_surface 无开启记录），且洗碗机处于运行状态（OperationalState=1）。即使考虑烹饪产生的热量，室内温度也不可能达到 260°C 以上，该数值远超物理极限。",
    "推理步骤 3: 对比其他房间数据，卧室和客厅温度变化平缓且符合昼夜温差规律（卧室约 21-22°C，客厅约 22-23°C），唯独厨房传感器数据呈现非物理性的剧烈波动和持续高位，排除了环境温度骤升的可能性，确认为传感器硬件故障或软件校准失效。"
  ],
  "key_evidence": [
    "19:05 - 19:53 期间，kitchen_temp_sensor 读数从 2431 线性/非线性上升至峰值 2677，随后缓慢下降但仍远高于正常室温。",
    "在此期间，kitchen_window_contact 保持关闭 (False)，且 cook_surface 未检测到加热操作，物理上不可能产生如此高的温度。",
    "同一时间段内，living_room_temp_sensor 和 bedroom_temp_sensor 读数稳定在合理范围 (2100-2400)，形成鲜明对比。"
  ],
  "recommended_actions": [
    "立即标记厨房温度传感器为“故障”状态，并在智能家居系统中暂时屏蔽其报警功能，防止误报火灾警报。",
    "安排技术人员上门检查厨房温度传感器硬件，进行重新校准或更换新传感器。",
    "在维修完成前，建议用户手动关注厨房实际温度，避免依赖自动化温控系统。"

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。

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。
