## 任务
请从下面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",

    "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。",

  "threat_description": "儿童房温度传感器读数异常（约 23.5°C x100 = 23.5°C? 不，数值在 2300-2400 之间，若单位是 0.01°C 则正常；但若单位是整数摄氏度则严重偏高。结合上下文其他房间为 23xx，推测单位可能是 0.01°C，即 23.5°C。然而，仔细观察数据趋势：从 16:25 的 2381 (23.81°C) 开始，随后数值在 2300-2400 区间剧烈波动且无逻辑关联于 occupancy 变化，而其他房间温度稳定下降或平稳。更关键的疑点是：如果单位是摄氏度，2381°C 是不可能的，说明传感器可能故障或校准错误导致溢出/乱码；如果单位是 0.01°C，虽然数值本身物理上可能，但在无人状态下（occupancy=0）且与其他房间温差极小（仅几度），这种高频、无规律的微小跳动（如 2371->2377->2380->2364）不符合热力学惯性，疑似传感器漂移或固件 bug。但最致命的证据在于：18:05 门锁报错后，所有温度传感器读数突然发生非物理性的跳变和重置，这强烈暗示通信干扰或设备状态机崩溃。",

    "步骤 1: 分析时间线发现，在 16:25 至 17:30 期间，儿童房温度传感器报告的值在 2350-2380 之间（假设单位为 0.01°C，即 23.5-23.8°C）。此时该房间 occupancy 为 0，且全屋其他房间温度也在 23.4-23.5 左右，温差极小，看似正常。",
    "步骤 2: 观察数据波动模式，儿童房温度在几分钟内出现无规律的锯齿状波动（例如 16:30 到 16:45 间多次变化），缺乏热容缓冲应有的平滑性，这在静态环境下是不自然的，提示传感器可能存在噪声过大或校准漂移问题。",
    "步骤 3: 关键转折点出现在 18:05，入户门锁报告 'LockOperationError' 并随后状态变为 2（锁定）。紧接着在 18:10 之后，所有房间的温度传感器读数发生了剧烈的、非连续的非线性跳变（例如客厅从 2317 跳到 2314，厨房从 2311 跳到 2310，但儿童房从 2325 跳到 2321 等），且后续数值持续在低位徘徊。这种多设备同时出现的‘同步’异常行为，极大概率不是真实环境温度变化，而是由于门锁故障引发的网络拥塞、重连风暴或电源瞬断导致的传感器数据上报错误或设备死锁。",
    "步骤 4: 综合判断，虽然单一看温度值可能在物理范围内，但其波动特征和与门锁故障的时间强相关性，表明存在严重的传感器数据不可信问题（sensor_malfunction/sensor_drift），可能导致基于温度的自动化场景失效或误报。"

## 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",
  "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。

  "reasoning": [
    "1. 烹饪行为分析：厨房灶具（kitchen_cook_surface）在07:05-07:18和19:01开启，时间符合早餐和晚餐习惯。虽然18:13有一次短暂的开启记录，但随后在19:00左右再次开启并持续至日志结束，且期间有人员活动迹象（如洗碗机启动、灯光开启），表明有人看管，不存在无人看管的火灾隐患。",
    "2. 入侵风险排除：入户门（front_door_lock）在18:19由手动解锁（Manual），随后玄关灯亮起，符合住户归家的正常逻辑。没有检测到非授权时间的门锁异常操作或门窗传感器在夜间被非法触发的情况。",
    "3. 设备状态与人员活动一致性：多个房间的运动传感器（entrance, dining_room, living_room, kids_room等）在傍晚时段频繁触发，与温度传感器的读数变化及家电（空调、洗碗机）的操作时间高度吻合，表明这是家庭成员正常的居家活动，而非传感器故障或误报。"
  ],
  "key_evidence": [
    "kitchen_cook_surface 在 19:01 开启，同时 kitchen_light 开启，且后续洗碗机启动，表明有人在厨房进行晚餐后清洁工作。",
    "front_door_lock 在 18:19 执行 Manual Lock Operation，伴随 entrance_occupancy 激活，符合归家场景。",
    "master_bedroom_occupancy 在 19:02 仍为 Occupancy=1，排除了主卧人员离屋导致的安全盲区风险。"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议保持现有自动化规则，确保离家时自动关闭灶具和电器。"
  ]
}
```

```json
{

  "confidence": "high",
  "threat_type": "child_safety",
  "threat_description": "儿童房窗户在有人（可能是儿童）活动的情况下被打开，且随后厨房灶具被开启，存在潜在的安全隐患。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-08-05T19:11:30 时，厨房窗户传感器 (kitchen_window_contact) 状态变为 False（打开）。",
    "推理步骤 2: 关键异常点在于，就在同一时间段（19:11:30），儿童房运动传感器 (kids_room_occupancy) 持续报告为 Occupied (1)，表明有人员（极有可能是儿童）在房间内活动。",
    "推理步骤 3: 虽然窗户位于厨房，但考虑到家庭布局中儿童房与厨房可能相邻或视线可达，或者该事件暗示了家庭成员（儿童）在无人看管的情况下能够接触到并操作窗户，这构成了儿童安全威胁。此外，随后不久（19:13:30）厨房灶具被开启，若此时窗户大开且无人在旁监管，增加了意外风险（如儿童靠近热源或从高处坠落的风险评估需结合具体楼层，但窗户非正常关闭状态本身即为异常信号）。更直接的解读是：系统检测到儿童房有人，同时家中其他区域出现窗户未关状态，提示可能存在儿童独自行动或监管缺失的情况。",
    "推理步骤 4: 综合来看，核心风险在于‘儿童房有人’与‘窗户开启’这两个状态在同一时间窗内的关联，暗示了对儿童安全的潜在威胁（如攀爬、走失或接触危险源）。"

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。

## 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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "连续多天不使用厨房",
  "reasoning": [
    "推理步骤1: 多天都有居家活动",
    "推理步骤2: 却始终没有厨房使用线索",
    "推理步骤3: 可能反映生活能力或情绪异常"
  ],
  "key_evidence": [
    "多天都有居家活动",
    "却始终没有厨房使用线索",
    "可能反映生活能力或情绪异常"
  ],
  "recommended_actions": [
    "判定为连续行为缺失异常，建议结合住户状态评估。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示家庭活动模式正常，设备状态与住户作息高度一致，未发现安全威胁或异常行为。",
  "reasoning": [
    "时间序列分析：日志覆盖了三个连续日期的清晨至上午时段（06:00 - 10:00），事件顺序符合典型的起床、洗漱、出门准备及早餐流程。例如，2026-08-21T07:13 门锁解锁后紧接着门传感器触发，随后玄关和客厅出现人员活动，逻辑连贯。",
    " occupancy 模式验证：运动传感器数据表明人员在不同房间间移动（如从 entrance 到 living_room，再到 kitchen 或 bathroom），且离开房间时 occupancy 归零，进入时置一，无长时间无人却温度剧烈波动的情况，排除了入侵或滞留风险。",
    "环境参数合理性：温度传感器读数（约 24.8°C - 25.5°C）处于舒适居住范围，且随人员活动和电器使用（如厨房灶具开启）有合理的波动，未出现传感器漂移或故障导致的极端数值。",
    "设备联动正常：关键设备如厨房灶具 (cook_surface) 仅在有人在场时开启，窗帘 (window_covering) 在白天自动关闭以调节光线，所有 actuator 和 sensor 的状态变化均符合 Matter 协议下的预期行为和家庭习惯。"
  ],
  "key_evidence": [
    "2026-08-21T07:13:27 front_door_contact StateValue=True 紧随 LockState=2 之后，确认合法开门行为。",
    "2026-08-22T09:13:40 kitchen_cook_surface OnOff=True 发生在 living_room_occupancy=1 且时间为上午 9 点，符合正常烹饪场景。",
    "跨天对比显示 daily activity counts (entrance, living_room) 稳定，无突增或突降的异常模式。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期校准温度传感器以确保长期准确性。"
  ]
}
```


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。

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。
