## 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",

    "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，设备日志显示独居老人的日常活动模式稳定且符合预期。",
  "reasoning": [
    "1. 活动模式一致性分析：对比2026-08-16至08-18的跨天摘要数据，各房间的活动计数（如living_room约209-210次，bedroom约240-242次）保持高度稳定，表明住户的生活作息规律，无突发的长时间静止（可能暗示跌倒或昏迷）或异常的高频活动。",
    "2. 关键区域行为逻辑验证：日志显示厨房（kitchen）和客厅（living_room）在早晨7:30-10:00期间有持续的运动传感器触发（Occupancy=1），这符合老人起床、准备早餐及晨间活动的正常行为轨迹。没有发现无人时的烹饪设备开启或长时间滞留厨房等“unattended_cooking”迹象。",
    "3. 环境与安全状态检查：温度传感器读数在合理范围内波动（客厅约25°C，卧室约24°C），无极端高温提示火灾风险。入户门传感器仅在早晨短暂记录到状态变化（可能是开门/关门动作），随后恢复常态，无非法入侵特征。所有烟雾报警器和漏水传感器在提供的片段中未触发告警。"
  ],
  "key_evidence": [

  "threat_description": "客厅温度传感器报告的数据严重异常（数值在 2500-2560 之间），远超正常室温范围，表明传感器故障或校准错误。",
  "reasoning": [
    "1. 数据合理性分析：日志中 living_room_temp_sensor 报告的 MeasuredValue 持续在 2500 至 2560 之间波动。根据 Matter 协议标准及物理常识，环境温度通常在 -40°C 到 +85°C 之间，即 40000 到 85000 的毫开尔文 (mK) 单位，或者如果是摄氏度则应在 0-35 左右。当前数值若解读为摄氏度则不可能；若解读为 mK，则对应约 2.5°C 至 2.6°C，这与夏季（8 月）室内空调开启或自然升温的环境（日志显示卧室温度约 24°C/24000mK）完全不符。",
    "2. 跨设备对比验证：同一时间段内，bedroom_temp_sensor 和 kitchen_temp_sensor 报告的数值约为 2400-2500 (对应 24-25°C)，符合人体舒适区及夏季室内常态。唯独客厅传感器读数出现数量级偏差或单位混淆，导致其显示的“温度”比实际低约 20 多度（如果按 mK 算）或者是一个毫无意义的巨大数字（如果误读为 C）。",
    "3. 行为模式关联：尽管传感器读数异常，但 occupancy_sensor 显示老人有正常的活动轨迹（起床、去厨房、回卧室等），且其他房间温度正常，说明并非全屋断电或极端天气导致，而是单一设备故障。对于独居老人家庭，错误的温度反馈可能导致空调系统无法正确调节（例如因误报低温而不开启制冷，或因逻辑混乱频繁启停），存在健康隐患。"

  "key_evidence": [
    "living_room_temp_sensor 在 2026-08-16T07:40:00 至 2026-08-17T11:15:00 期间持续报告 2500-2560 的数值，而同期 bedroom_temp_sensor 报告约 2400-2500 的合理数值。",

## 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",

    "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。

  "threat_type": "none",

    "推理步骤 1: 时间分析显示，从 02:10 到 05:38（约 3.5 小时），所有房间的运动传感器（living_room, bedroom, kitchen, bathroom, entrance）均持续报告 Occupancy = 0，表明屋内无人移动。",
    "推理步骤 2: 在长达数小时的无人状态下，客厅和厨房的温度传感器读数却持续攀升，从 00:10 的 22.75°C (2275mK) 上升至 04:15 的 24.18°C (2418mK)，这种在无人员活动的情况下温度显著升高的现象不符合正常物理规律（除非空调故障开启加热，但日志中未见空调控制指令，且通常夜间会关闭）。",
    "推理步骤 3: 结合住户为“独居老人”的背景，长时间无活动伴随环境参数异常（高温、无生命体征迹象），极大概率暗示老人可能处于昏迷、跌倒无法动弹或突发疾病状态，而非正常的睡眠行为（通常会有翻身等微小动作或呼吸产生的热扰动，且不会导致室温持续被动升高）。",
    "推理步骤 4: 虽然 05:38 卧室灯被打开，但这可能是家人发现异常后的介入，或者是老人苏醒后的反应，但在之前的 3.5 小时内缺乏任何安全确认信号，构成了高危的健康/安全事件。"
  ],

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",

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。

    "3. 环境参数合理：温度传感器读数（如客厅25°C左右，卧室24°C左右）处于舒适区间，且随时间缓慢变化，无剧烈波动，排除了传感器故障或极端天气导致的异常。",
    "4. 门锁与入口安全：入户门传感器仅在早晨特定时间段（如08:30, 09:00等）有短暂活动记录，且伴随玄关灯/运动传感器联动，推测为正常外出或取物行为，无非法入侵特征（如深夜开锁、长时间未关门）。"

    "推理步骤 2: 结合 Matter 协议标准及常识，室内环境温度通常在 -10°C 至 50°C 之间（即 283K-323K）。日志中的数值（约 2500+）远超此范围，且呈现无规律的微小波动，不符合真实温度变化曲线。",
    "推理步骤 3: 考虑到住户为独居老人，若该传感器数据被用于自动化逻辑（如误判高温开启制冷或关闭），将直接威胁老人健康；同时，作为安全分析，必须区分这是真实火灾还是设备故障，当前数据特征强烈指向硬件故障或校准错误而非真实火情。"

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: ..."
  ],
  "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": [
    "继续监测，无需立即处置。"
  ]
}

```json
{

  "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",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",

  ]
}
```

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

    "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",

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: ..."
  ],
  "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，灶具使用行为符合独居老人日常烹饪习惯，无无人看管或火灾风险。",
  "reasoning": [
    "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。"
  ],
  "key_evidence": [
    "7月16日 12:00-12:22 和 7月17日 12:05-12:28 灶具开启期间，厨房运动传感器持续检测到人（kitchen_occupancy = 1）。",
    "灶具开启时长合理（约20-30分钟），符合单次烹饪行为特征，非长时间无人看管。",
    "无烟雾报警器（smoke_co_alarm）或一氧化碳报警触发记录。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议家属定期查看日志，确认05:52的灶具开启是否为老人习惯性行为（如热牛奶），若确认为误触可考虑调整设备灵敏度或增加防误触设置。"
