## 任务
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

  "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",

  "reasoning": [
    "1. 时间分析：事件发生在 2026-07-19 18:40 左右，属于典型的傍晚下班回家时间段。",
    "2. 动作序列分析：18:40 门锁状态变为 'Locked' (State=2，通常表示已上锁或处于锁定状态，但在Matter中需结合上下文，此处结合后续开门动作，更可能是指从外部解锁或刚完成开锁动作后的状态变化，或者日志记录的是开锁瞬间的状态)。紧接着 18:41 门传感器显示 'False' (通常 False 代表门关闭，True 代表打开，或者反之，取决于具体实现，但关键在于与锁状态的时序关联)。18:42 玄关灯亮起。这一系列动作（开锁 -> 进门/门状态变化 -> 开灯）构成了完整的“回家”行为链。",
    "3.  occupancy 验证：18:43 客厅运动传感器检测到有人 (Occupancy=1)，随后在 19:00 恢复为无人 (Occupancy=0)，这符合住户进入室内活动后短暂离开或传感器超时归零的正常模式。所有设备状态变化时序紧密且逻辑自洽，未发现非法入侵、尾随或设备故障迹象。"

## 任务
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：

```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_description": "日志显示的行为模式符合正常的家庭晚间活动规律，未发现安全威胁或设备异常。",
  "reasoning": [
    "1. 门锁状态分析：7月2日和3日的 `front_door_lock` 事件均显示为手动解锁（LockOperationType=1）后进入未锁定状态（LockState=2），随后在傍晚/夜间再次手动上锁。这符合住户下班回家、在家活动、晚上休息前反锁门窗的正常生活逻辑，无暴力破解或非法入侵迹象。",
    "2. 人员活动轨迹一致性： occupancy_sensor 数据显示，早晨主卧和儿童房有人活动，随后客厅、餐厅等公共区域在傍晚时段（17:00-19:00）出现密集的人员占用信号，且伴随空调开启、灶具使用等行为，表明家庭成员正常聚集在家中，无长时间无人居住后的突然闯入特征。",
    "3. 环境与安全设备正常：厨房灶具仅在晚餐时间短暂开启，未见超时未关风险；温度传感器读数随时间缓慢变化，符合室内热惯性，无突变；未检测到烟雾报警或漏水警报。",
    "4. 跨天行为对比：7月4日数据量显著减少（living_room=49 vs 前两天~115），但仅展示了部分片段，且显示的 occupany 变化（如儿童房从1变0）符合正常作息，不足以构成 'abnormal_inactivity' 的充分证据，更可能是采样窗口不同或用户外出，结合前两天的活跃表现，整体判定为正常波动。"
  ],
  "key_evidence": [
    "7月2日 18:00 和 7月3日 17:46 的手动上锁操作与随后的室内人员占用信号匹配，符合归家逻辑。",
    "傍晚时段（17:00-19:00）多个房间（Living Room, Dining Room, Kids Room）同时出现 Occupancy=1，符合家庭团聚场景。",
    "无 DoorLock.LockState=0 (Unlocked) 在非正常时间段（如深夜）由非手动来源触发的记录。",
    "TemperatureMeasurement 数值变化平缓（如 2538 -> 2551 -> 2365），无剧烈跳变暗示传感器故障。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控早晚高峰时段的门锁状态，确保自动上锁功能（如有配置）正常工作。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",

  "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": [
    "正常样本是每天傍晚回家时间略有波动；异常样本是在固定下午时点出现活动。"
  ],
  "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
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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",

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. 人员活动模式分析：跨天摘要显示 living_room 和 bedroom 在白天有较高活跃度（如8月9日living_room=193, bedroom=207），晚间活跃度下降但仍有零星活动（如17:00-19:00的occupancy=1），符合典型的居家作息。没有发现长时间无人却有人活动的矛盾，也没有发现深夜异常活跃的情况。",
    "3. 环境传感器数据合理性：温度传感器读数（如2497, 2503等）转换为摄氏度约为24.97°C, 25.03°C，处于舒适的室内温度范围。温度随时间缓慢变化（如早晨升温，傍晚降温），符合物理规律，未发现传感器漂移或故障导致的突变。",
    "4. 关键事件关联：8月10日18:29入户门关 -> 18:31客厅灯开 -> 18:44客厅有人，这一连串动作逻辑连贯，是标准的“回家”自动化或手动操作序列，无尾随或强行闯入迹象。"

    "温度读数稳定在22-26°C之间，无剧烈波动或无效值（除个别None外，随后恢复正常）",

    "推理步骤 4: 虽然 2026-08-10T18:45:00 出现 2652 的极高读数，但考虑到前一日已确认传感器不稳定，该读数更可能是故障延续或校准错误，而非真实的烹饪过热（因为此时 household occupancy 显示有人在家，但未触发烟雾报警器或其他关联事件，且数值缺乏持续性上升特征）。"

## 任务
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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",

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。

  "threat_description": "厨房温度传感器数据严重异常，数值远超物理可能范围且呈现非自然线性增长，疑似传感器故障或信号干扰。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kitchen_temp_sensor 在 17:50 至 18:40 期间报告的温度值（如 2339, 2458, 2515... 直至 2710）单位若为毫开尔文 (mK) 则对应约 20°C-24°C，看似正常；但若单位为摄氏度 (°C) 或原始计数未转换，则数值高达 27°C+ 甚至更高。然而，结合上下文其他房间温度稳定在 23°C 左右，而厨房数值持续单调递增且幅度巨大（从 2339 到 2710），这种线性漂移不符合任何真实的热力学过程（如烹饪升温通常是非线性的且有上限）。",
    "推理步骤 2: 对比同一时间段内其他房间（客厅、主卧、次卧）的温度传感器读数，它们均在 22-23°C 之间波动，变化平缓且符合环境常态。唯独厨房传感器表现出极端的‘漂移’行为，数值随时间推移不断增大，最终达到 2710（若为 mK 约为 23.8°C，但增长速率过快；若为其他单位则完全不合理）。考虑到 Matter 协议中温度通常以 mK 上报，2710 mK = 23.87°C，虽然数值本身在合理范围内，但其**变化模式**（每 5-10 分钟增加数十个单位，且与其他房间温差逐渐拉大至不可能程度）显示出典型的传感器校准失效或固件计算错误特征。",
    "推理步骤 3: 进一步观察，在 18:53 该传感器突然返回 `None`，随后在 18:55 又恢复到一个相对合理的数值 (2584 mK ≈ 22.6°C)，这表明设备经历了某种重置或状态切换。这种‘异常高值/快速漂移 -> 归零/跳变 -> 恢复正常’的模式是传感器硬件故障、通信丢包导致的乱码、或软件逻辑错误的典型签名，而非真实的火灾风险（真实火灾会导致温度急剧飙升并伴随烟雾报警，且不会突然归零再恢复）。",
    "结论：综合判断，厨房温度传感器存在严重的测量漂移或 malfunction 现象，导致数据不可信。虽然当前数值未直接触发火灾警报，但该故障可能导致基于此数据的自动化决策（如误判过热关闭电器）失效，属于需要立即关注的设备健康隐患。"

    "kitchen_temp_sensor 在 17:50 至 18:40 期间数值从 2339 线性增长至 2710，而其他房间温度稳定在 2300 左右，显示出不合逻辑的单向漂移。",
    "在 18:53 该传感器突然报告 `MeasuredValue = None`，随后在 18:55 恢复，这种中断和恢复模式强烈暗示硬件或通信层面的故障。",
    "厨房温度读数与其他所有房间传感器的读数趋势完全背离，缺乏物理上的热传导一致性。"

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
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

请按以下 JSON 格式回答：

```json

    "2. 人员动线合理：17:01 玄关有人后，随后客厅、主卧、儿童房、餐厅等区域的运动传感器依次被触发（17:51-18:32），且持续有 occupancy=1 的记录，表明家庭成员在家中正常活动，无长时间静止或异常消失情况。",
    "3. 设备操作符合生活场景：18:07 回家后开启客厅灯光和空调，18:35 开启厨房灯并启动灶具，这是典型的晚餐准备流程。虽然开启了灶具，但后续日志中未出现烟雾报警器报警或长时间无人看管灶具的极端情况（日志截止于18:45，仅过去10分钟，属于正常烹饪初期）。",
    "4. 温度数据解读：温度传感器数值（如2340, 2322）明显高于室温（通常20-30摄氏度），推测单位为0.1摄氏度或存在特定编码，但各房间温度变化平缓且一致（均在23度左右波动），无剧烈跳变或传感器故障迹象，不影响安全判断。"

## 任务
以下是过去 3 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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: ...",

    "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。

    "1. 门锁操作分析：8月10日的三次门锁操作（07:48, 16:01, 17:48）均为 `LockOperationType=1` (Lock) 且 `OperationSource=Manual`。结合时间看，早晨出门、下午外出/回家后的反锁或检查，属于常规行为。没有发现非法解锁（Unlock）或异常时间的频繁尝试记录。",
    "2. 人员活动模式分析： occupancy_sensor 数据显示，白天大部分房间无人（Occupancy=0），傍晚至夜间（17:30后）客厅、餐厅、主卧等区域出现人员活动（Occupancy=1）。这种‘白天无人、晚上有人’的模式符合典型的居家作息规律。",
    "3. 传感器数据合理性：温度传感器读数在合理范围内波动（约22-25°C），且变化趋势平缓，符合室内环境温度随空调或自然通风变化的特征，无突变或停滞迹象，排除传感器故障。",
    "4. 跨天一致性：8月8日和9日的活动摘要与日志片段一致，均显示晚间有活动，早晨安静，行为模式稳定，无突发的异常静默或混乱活动。"

    "living_room_occupancy 在 2026-08-10T17:48:04 变为 1，紧随门锁操作之后，表明有人进入并触发感应，逻辑连贯。",
    "各房间温度传感器数值在 2200-2550 (22-25.5°C) 之间平稳波动，无异常跳变。"
  ],
