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

  "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",

## 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: 正常样本是短时起夜；异常样本在厨房等非卧室区域停留过久。"
  ],
  "key_evidence": [
    "正常样本是短时起夜；异常样本在厨房等非卧室区域停留过久。"
  ],
  "recommended_actions": [

  ]
}

  "threat_type": "health_concern",
  "threat_description": "独居老人在凌晨时段出现长时间无活动且卧室灯光异常开启，随后伴随室内温度持续异常升高，疑似老人夜间跌倒或突发疾病导致无法移动及空调/加热设备失控。",
  "reasoning": [
    "时间异常：日志显示在 2026-07-30T02:18:00 至 05:33:04 期间，所有房间（包括客厅、厨房、玄关）的运动传感器均报告无人 (Occupancy=0)，但卧室灯在 02:18:00 被打开，且直到 05:33:04 才被再次打开（可能是误触或自动感应），中间长达 3 小时无任何人员活动记录。对于独居老人，深夜长时间静止是跌倒或健康恶化的典型特征。",
    "环境数据矛盾：在无人活动的同时，客厅和厨房的温度传感器读数从正常的 22°C 左右急剧上升至 24°C 以上（例如 04:00 时客厅达到 2409 mK ≈ 24.1°C，且持续攀升）。考虑到此时段通常应处于睡眠降温状态，这种升温可能意味着老人因无法移动而靠近热源，或者空调/暖气系统故障导致室温过高，加剧了潜在的健康风险。",
    "行为模式缺失：正常作息下，凌晨 2 点起床开灯后应有后续活动（如去卫生间、喝水等），但日志中 bathroom_occupancy 直到早上 06:04 才首次检测到有人进入，且之后直到晚上 20:37 才有明确的卧室灯光关闭/开启的完整交互序列。这表明老人在凌晨 2 点至 6 点之间完全失去了自主行动能力。"
  ],
  "key_evidence": [
    "2026-07-30T02:18:00 卧室灯开启，但随后 3 小时内所有运动传感器均为 0，无其他任何活动迹象。",
    "凌晨时段（02:00-05:00）室内温度持续异常上升，偏离正常夜间休息时的温度曲线。",
    "从凌晨 02:18 到早上 06:04，卫生间运动传感器长时间未检测到活动，排除了老人起夜的可能性。"
  ],
  "recommended_actions": [
    "立即触发紧急联系机制：通过短信、电话或智能音箱大声询问老人状况，并尝试远程解锁入户门以便家人或急救人员进入。",
    "通知家属或紧急联系人：将当前情况（深夜静止、温度异常、灯光状态）同步给监护人或社区服务中心。",
    "检查设备状态：确认是否为传感器故障（如红外遮挡），但在独居老人场景下，必须优先按真实紧急情况处理，不可仅等待人工复核。"

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",
  "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": "未检测到安全威胁或异常情况，设备日志显示住户活动规律，门锁状态正常。",
  "reasoning": [
    "1. 门锁状态分析：重点关注的 front_door_contact 在三天内多次报告为 False（关闭/锁定），且仅在 8月29日 08:28 有一次手动上锁记录，8月31日 08:39 有锁定状态变更。没有发现非法开启、暴力破解或长时间未锁门的异常模式。入户门传感器与门锁操作逻辑一致，符合独居老人早晨出门或整理仪容的习惯。",
    "2. 人员活动轨迹分析： occupancy_sensor（运动传感器）在客厅、卧室、厨房和玄关均有频繁触发，表明住户在这三天内保持正常的日常活动（如起床、做饭、休息）。特别是厨房灶具在 8月30日 11:09 被开启，随后有温度变化，符合正常的烹饪行为，未发现无人看管导致的火灾风险。",
    "3. 环境数据一致性：各房间温度传感器读数随时间缓慢变化，符合昼夜温差和空调/自然通风的影响，无突变或传感器故障迹象。卫生间和浴室的 occupancy 变化也符合正常如厕或洗漱的频率。",
    "4. 综合判断：所有事件均在合理的时间窗口内发生，设备间联动逻辑正常（如人进厨房灯亮或灶具使用），未发现入侵、跌倒、健康危机或设备故障的迹象。"
  ],
  "key_evidence": [
    "front_door_contact 持续为 False (Closed/Locked)，无异常开启记录",
    "kitchen_cook_surface 在 8月30日 11:09 开启，伴随 kitchen_occupancy 存在，属正常烹饪",
    "多房间 occupancy_sensor 全天高频触发，证明住户活动正常，无长时间静止（跌倒风险低）"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预",
    "建议定期校准温度传感器以确保读数长期准确性"
  ]
}
```

{
  "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": [
    "正常样本仍保持日常出门；异常样本后续数天只剩室内活动。"
  ],
  "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。

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。

    "1. 分析灶具使用模式：日志显示在7月16日和17日，厨房灶具（kitchen_cook_surface）均被开启并随后关闭。7月16日开启时间为05:52（可能为误触或极早准备早餐/热奶），12:00-12:22开启；7月17日12:05-12:28开启。这些时间段（尤其是中午12点左右）是典型的午餐准备时间。",
    "2. 验证人员在场情况：在灶具开启期间，厨房运动传感器（kitchen_occupancy）持续报告有人（Occupancy=1）。例如7月16日12:04至12:22期间，以及7月17日12:13至12:43期间，均有 occupancy 信号支持有人在厨房活动。这排除了‘无人看管烹饪’（unattended_cooking）的风险。",
    "3. 检查环境安全指标：虽然日志中未直接显示烟雾报警器触发，但灶具开启时间短（约20-30分钟），且结束后立即关闭，没有长时间持续加热导致温度异常升高的迹象（厨房温度传感器读数在正常范围内波动，如2500-2550之间，未见急剧上升）。同时，没有一氧化碳报警器的触发记录。",
    "4. 综合判断：考虑到住户为独居老人，偶尔的早起操作（05:52）和规律的午餐操作属于正常生活规律。所有关键设备状态变化逻辑自洽，未发现入侵、跌倒或设备故障迹象。"

## 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",
  "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": "未检测到安全威胁或异常情况，设备日志显示住户活动规律且环境参数正常。",
  "reasoning": [
    "1. **活动模式分析**：日志显示住户在每天上午10:30至下午13:30之间活跃于客厅、厨房和卧室，符合独居老人白天的常规作息（如起床、准备午餐、休息）。入户门传感器仅在特定时间点短暂触发（如11:22, 11:57），随后无持续异常开启记录，表明没有非法入侵迹象。",
    "2. **烹饪安全评估**：虽然重点关注的 kitchen_light 多次开启（05:58, 12:05, 17:05等），但厨房灶具(cook_surface)状态未在日志中显示为“开启”或高温状态，且厨房温度传感器读数稳定在24-25°C左右，未出现因长时间无人看管烹饪导致的温度急剧升高现象。因此排除 unattended_cooking 风险。",
    "3. **设备健康检查**：所有温度传感器读数在合理范围内（23-26°C），无极端值；运动传感器频繁触发与住户活动一致；唯一的一次 `kitchen_temp_sensor` 读数为 `None` (11:29) 后迅速恢复，属于正常的通信抖动或瞬时故障，不构成 sensor_malfunction 的持续性证据。"
  ],
  "key_evidence": [
    "厨房温度传感器读数稳定在24-25°C区间，无异常升温，佐证无火灾或未关火风险。",
    "入户门传感器仅在短时间窗口内触发，且伴随玄关/客厅人员活动，符合正常出入逻辑。",
    "各房间运动传感器活动轨迹连贯，未发现长时间静止后的突然活动（跌倒风险低）或完全静默（失联风险低）。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需紧急干预。",
    "建议定期校准厨房温度传感器，确保数据连续性，尽管本次波动看似正常。"
  ]
}
```

{
  "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": [
    "正常样本午餐时间有小幅波动；异常样本跨天明显后移。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}

## 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: ...",
    "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": "未检测到安全威胁或异常行为，设备日志显示独居老人的日常活动模式稳定且符合逻辑。",
  "reasoning": [
    "1. 活动模式一致性分析：对比2026-08-08至08-10的跨天摘要数据，各房间的活动计数（如living_room约208-209次，kitchen约239-242次）保持高度稳定。这种稳定性表明住户的生活作息规律，没有突发的长时间静止（可能暗示跌倒或昏迷）或异常的剧烈活动。",
    "2. 厨房安全状态检查：虽然重点设备包含kitchen_light，但日志中并未出现灶具(cook_surface)长时间开启后无人看管的情况。相反，在08-10T11:25:00记录到灶具关闭(OnOff=False)，随后有正常的温度传感器读数恢复和人员活动，符合正常的烹饪结束流程。未发现fire_risk或unattended_cooking迹象。",
    "3. 传感器数据合理性验证：温度传感器读数（如客厅25°C左右，卧室24°C左右）处于正常舒适区间，无极端值或跳变，排除了sensor_malfunction或sensor_drift。运动传感器(Occupancy)频繁触发且与时间分布合理（白天活跃），符合独居老人在家活动的特征。",
    "4. 门窗与锁具状态：入户门传感器仅在特定时间点（如11:34, 12:14等）短暂触发，且伴随玄关灯或运动传感器的联动，推测为正常的短暂外出或取物行为，未见非法入侵(intrusion)或尾随(tailgating)的持续异常模式。"
  ],
  "key_evidence": [
    "连续三天各房间活动计数高度一致（例如Kitchen活动数分别为239, 239, 242），证明生活规律稳定。",
    "08-10T11:25:00 kitchen_cook_surface OnOff=False，表明烹饪结束后设备已关闭，无未关火风险。",
    "所有温度传感器读数均在合理范围内（23-25°C），无硬件故障迹象。",
    "运动传感器在白天时段频繁激活，符合独居老人日间在家活动的正常行为模式。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",
    "建议定期校准温度传感器以确保长期数据准确性，尽管当前数据正常。"
