## 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",
    "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符合独居老人的日常作息模式。",
  "reasoning": [
    "1. 活动模式一致性分析：对比2026-08-04、05、06三天的日志，住户在早晨7:30-9:00期间活跃于厨房（kitchen_occupancy=1）和客厅（living_room_occupancy=1），随后在卧室（bedroom_occupancy=1）有短暂停留，这符合老人起床、准备早餐/洗漱、休息的常规生活节奏。三天内的时间点和活动区域高度重合，无显著偏离。",
    "2. 门锁与入侵检测：入户门传感器（front_door_contact）仅在08-06出现一次关闭状态（False），结合该时间点玄关运动传感器（entrance_occupancy）被触发，表明是住户正常出门或回家，而非非法入侵。其余时间门窗状态稳定，无异常开启记录。",
    "3. 环境与安全指标正常：所有温度传感器读数在合理范围内（约24-25°C，Matter协议中通常单位为0.01摄氏度，即24.42°C等），无极端高温提示火灾风险。烟雾报警器（smoke_co_alarm）和漏水传感器（water_leak_detector）在整个日志片段中未触发任何报警事件。",
    "4. 传感器状态健康： occupancy_sensor 的状态变化（0到1或1到0）具有明确的时间间隔和逻辑关联（如人进入房间后持续一段时间才离开），未发现传感器卡死（stuck）或数据漂移（drift）导致的异常高频跳动或长期静止不动的情况。"
  ],
  "key_evidence": [
    "连续三天早晨7:30-9:00期间，kitchen_occupancy 和 living_room_occupancy 均呈现规律的 '1' (有人) 状态，行为模式一致。",
    "08-06T08:38:02 front_door_contact 变为 False，同时 entrance_occupancy 为 1，符合正常出入行为。",
    "全时段内 smoke_co_alarm 和 water_leak_detector 无任何报警触发记录。",
    "温度读数稳定在舒适区间，无异常波动。"
  ],
  "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准确性，尽管目前看来工作正常。"
  ]
}
```

{
  "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。"

## 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情况，设备日志显示独居老人的日常活动规律且正常。",
  "reasoning": [
    "1. 活动模式分析：日志显示老人在上午10:30至下午14:00期间活跃，主要分布在客厅、厨房和卧室。这符合独居老人白天起床后在客厅休息、去厨房准备食物/饮水、偶尔回卧室休息的日常作息规律。",
    "2. 关键设备行为验证：厨房灯（kitchen_light）仅在特定时间点开启（如05:51, 12:05, 12:35, 12:15），且伴随厨房运动传感器（kitchen_occupancy）的激活，表明有人在使用厨房，不存在无人看管的烹饪风险或设备故障导致的常亮。",
    "3. 环境数据合理性：温度传感器读数（如2542代表25.42°C）随时间缓慢变化，符合室内环境温度自然波动特征，无剧烈跳变暗示传感器故障。门窗传感器和门锁状态虽未在片段中频繁触发异常开合，但结合运动传感器的人体存在，未发现非法入侵迹象。",
    "4. 健康与安全指标：所有房间均有运动传感器检测到人体存在，未发现长时间无活动的“abnormal_inactivity”或跌倒后的静止情况。烟雾报警器和漏水传感器无报警记录。"
  ],
  "key_evidence": [
    "厨房灯与厨房运动传感器联动正常，无长时间无人值守的烹饪场景。",
    "多房间（客厅、卧室、厨房）在白天时段持续有运动传感器触发，证明住户处于清醒和活动状态。",
    "温度数据平稳，无突变或停滞，排除传感器卡死或漂移。"
  ],
  "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。"
  ]

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
{
  "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。

    "2. 关键区域活动正常：厨房（kitchen_occupancy）在早晨07:00-08:00期间频繁触发占用信号，符合老人起床后准备早餐或饮水的习惯；客厅（living_room_occupancy）在上午时段持续有活动记录，表明老人在家中处于活跃状态。",
    "3. 环境与安全设备状态良好：温度传感器读数在合理范围内（24-25°C左右），无异常高温提示火灾风险；入户门传感器（front_door_contact）仅在早晨短暂关闭（False），随后保持开启或无人经过，未见非法入侵迹象；烟雾报警器和水浸传感器在日志片段中未触发报警事件。",
    "4. 逻辑连贯性：早晨出门/进入玄关（entrance_occupancy）与大门状态变化同步，卫生间使用（bathroom_occupancy）时间短暂且正常，整体动线符合独居老人的日常生活逻辑，未发现尾随、滞留或其他可疑行为。"
  ],
  "key_evidence": [

    "室内温度维持在舒适区间，无火灾或极端天气导致的安全隐患。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",

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。

    "2. 室内活动模式一致性：客厅 (`living_room`)、厨房 (`kitchen`) 和卧室 (`bedroom`) 的运动传感器在白天时段（08:00 - 11:00+）持续报告占用状态 (`Occupancy = 1`)，表明老人在家中活跃。这种跨房间的移动轨迹（如从卧室到厨房再到客厅）符合独居老人的日常生活逻辑。",
    "3. 环境数据稳定性：温度传感器读数在合理范围内波动（约 24°C - 25.5°C），没有突变的极端值，排除了传感器故障或火灾/漏水导致的紧急环境变化。烟雾报警器和燃气报警器无任何触发记录。",
    "4. 无跌倒或长时间静止迹象：虽然这是片段日志，但在选定的时间窗口内，多个房间的运动传感器交替激活，没有出现某单一区域长时间（数小时）完全无活动而其他地方却有人活动的情况，也未发现典型的跌倒后静止特征。"

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。

    "推理步骤 1: 时间窗口分析。日志显示在 02:18 卧室灯开启，随后在 02:30 至 03:55 期间，所有房间（包括客厅、卧室、厨房、卫生间、玄关）的运动传感器均报告为'0'（无人），持续时长超过 1.5 小时。对于独居老人而言，深夜长时间无活动属于异常模式。",
    "推理步骤 2: 环境数据关联。在此期间，客厅和厨房的温度传感器读数从约 23°C (2300 mK) 持续上升至接近 24°C (2398 mK)，而卧室温度相对平稳但略低。这种升温可能是由于空调/暖气未关闭导致的热量积聚，或者是人员被困在某个封闭空间（如浴室或卧室角落）产生的体热效应，亦或是设备故障导致的误报，但结合无人状态，需优先排除人员滞留风险。",
    "推理步骤 3: 行为逻辑推断。虽然 02:18 有开灯动作，暗示有人起床，但随后的长时间无活动记录与独居老人的正常作息（通常夜间起夜后不久即返回睡眠或进行短暂活动）不符。若老人发生跌倒或突发疾病，长时间无移动将导致危险状况升级。此外，后续直到 05:34 才有再次开灯记录，中间间隔过长，进一步证实了该时段内缺乏有效生命体征监测。"

## 任务
以下是过去 2 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",

## 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",
  "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: 正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "key_evidence": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "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": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}
