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: ...",

    "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": "health_concern",

  "threat_description": "日志显示独居老人的日常活动模式正常，无检测到入侵、火灾风险或设备故障等安全威胁。",
  "reasoning": [
    "时间线分析：所有事件均发生在白天（06:00 - 14:00），符合独居老人正常的起床、用餐和活动规律，未发现深夜异常活动或非授权时段的活动。",
    "行为一致性：厨房灶具 (kitchen_cook_surface) 的开启与关闭均有明确的 occupancy 传感器数据支持（有人在厨房时开启，有人离开后关闭），且持续时间合理（约 5-10 分钟），排除了无人看管烹饪的风险。",
    "环境状态稳定：客厅和卧室的温度传感器读数在 24°C-26°C 之间波动，处于舒适且安全的范围内；未检测到烟雾报警器触发或温度急剧升高的迹象。",
    "人员分布逻辑：运动传感器在各房间的状态变化连贯，例如从玄关进入后，客厅、厨房、卧室的占用状态随之更新，没有出现人员凭空消失或出现在不可能区域的逻辑矛盾。",
    "设备运行正常：窗帘开合、灯光开关等操作均伴随合理的上下文（如准备休息或调整光线），未见设备卡死或误报现象。"
  ],
  "key_evidence": [
    "厨房灶具操作严格遵循'人在操作'的逻辑，无长时间无人看管记录。",
    "全屋温度传感器读数稳定，无高温预警或烟雾报警信号。",
    "各房间 occupancy 传感器数据流转自然，符合单人活动的物理路径。"
  ],
  "recommended_actions": [
    "继续保持当前的设备监控频率，无需额外干预。",
    "建议定期（如每周）人工检查一次烟雾报警器和漏水传感器的电池及功能状态，作为预防性维护。"
  ]

## 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",

    "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": "日志显示独居老人的日常活动模式正常，无入侵、火灾或设备故障迹象。",
  "reasoning": [
    "1. 人员活动规律：日志中 occupancy_sensor（运动传感器）在 living_room, kitchen, bedroom, entrance 等区域频繁触发（值为 1），且时间分布符合白天居家活动的自然规律（如上午 10 点至下午 5 点），未见长时间无人但其他房间有活动的异常分离现象，也未见深夜异常活动。",
    "2. 温度数据合理：所有 temperature_sensor 报告的数值（如 2551, 2441 等）若按 Matter 标准解读为毫开尔文 (mK)，则对应约 22°C - 23°C，属于舒适的室内环境温度；即使直接视为摄氏度，也需结合上下文判断，但考虑到空调和窗帘的操作记录，环境控制是活跃的，排除了极端高温导致的火灾风险或传感器完全失效（漂移/卡死）。",
    "3. 设备状态一致：kitchen_light 的开关操作与厨房 occupancy 存在逻辑关联（人在厨房开灯），living_room 和 bedroom 的灯光及窗帘操作也与 occupancy 变化同步，未发现 actuator_stuck（执行器卡死）或 sensor_malfunction（传感器故障）的迹象。",
    "4. 安全设备正常：smoke_co_alarm（烟雾报警器）未触发报警事件，water_leak_detector（漏水传感器）无相关事件报告，door_lock（门锁）虽无直接开锁日志，但 entrance_occupancy 和 contact_sensor 的活动表明门扇有正常的进出开合，符合独居老人生活场景。"
  ],
  "key_evidence": [
    "多房间 occupancy_sensor 持续活跃，时间线连贯，符合单人日间活动特征。",
    "TemperatureMeasurement 数值稳定且在合理范围内，无急剧升高或异常低值。",
    "无任何 smoke_co_alarm 报警、water_leak 触发或 door_lock 异常锁定/解锁事件。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期（如每周）人工检查一次入户门锁电池及机械锁具功能，确保物理安全。"

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
{
  "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",

}
```

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。

    "推理步骤 2: 分析温度变化趋势。尽管厨房无人，但厨房温度传感器读数从凌晨 02:10 的约 23.3°C (2328 mK) 持续急剧上升，至 04:20:00 达到约 24.2°C (2423 mK)，并在短时间内（03:45）突破 24.0°C (2400 mK)。这种在无人员干预情况下的持续升温不符合正常环境热力学规律。",
    "推理步骤 3: 结合住户画像评估风险。住户为独居老人，反应速度可能较慢。厨房是家庭火灾高发区，持续的无人高温状态强烈暗示灶具未关闭、电器故障或烹饪遗留火源，构成了极高的火灾隐患。"

## 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",

}
```

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。

    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:05，属于独居老人的夜间睡眠时段，此时住户通常不在活动区。",
    "推理步骤 2: 占用状态分析。在温度急剧上升期间（02:10 - 04:05），厨房运动传感器 (kitchen_occupancy) 多次报告为 0（无人），仅在 02:10、02:35、02:50 短暂出现 1 的读数，随后又迅速归零或保持极低频率，表明该区域处于无人看管状态。",
    "推理步骤 3: 温度趋势分析。厨房温度传感器读数从 02:10 的约 23.3°C (2336 mK) 持续单调上升至 04:05 的约 24.0°C (2402 mK)，增幅显著且无回落迹象。相比之下，卧室和客厅温度虽有波动但相对平稳。这种在无人状态下厨房温度的持续攀升是典型的电器过热或灶具未关特征。",
    "推理步骤 4: 设备行为关联。虽然厨房灯在 02:50 开启，但这可能是自动感应或误触，无法解释长达近两小时的持续高温。结合独居老人背景，若发生此类情况，老人可能因听力下降或睡眠中未能察觉危险，导致火势蔓延。"

## 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": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "老人连续多天活动范围缩小",
  "reasoning": [
    "推理步骤1: 活动由多房间收缩到单一区域",
    "推理步骤2: 跨天持续出现",
    "推理步骤3: 提示功能退化或健康问题"
  ],
  "key_evidence": [
    "活动由多房间收缩到单一区域",
    "跨天持续出现",
    "提示功能退化或健康问题"
  ],

    "判定为老人活动范围异常缩小，建议关注健康状态。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "家庭环境运行正常，独居老人的活动模式符合预期，未发现入侵、火灾或设备故障等安全威胁。",
  "reasoning": [
    "入住与离开模式正常：日志显示老人通常在早上 7:00-8:30 之间起床并进入厨房/客厅开始日常活动，晚上在卧室停留直至次日清晨（如 2026-07-29 凌晨 00:30 卧室无人），跨天活动摘要中的房间占用计数稳定，符合独居老人的作息规律。",
    "温度数据合理：所有温度传感器读数均在正常范围内（约 24.1°C - 25.6°C）。虽然 Matter 协议中温度常以毫开尔文 (mK) 为单位报告（例如 2525 mK = 25.25°C），但数值波动平滑且无异常高温或低温漂移迹象，排除了火灾风险或传感器故障。",
    "关键安全事件逻辑自洽：入户门锁状态变化（LockState=2）发生在早晨开门时段，随后玄关和客厅立即检测到人员进入；厨房灶具关闭操作（OnOff=False）发生在上午 11:39，此时厨房有人且温度正常，属于正常的烹饪结束行为，未检测到未attended cooking 或烟雾报警触发。",
    "无异常传感器行为：所有运动传感器和接触传感器的状态切换均伴随合理的后续动作（如开门后灯亮、人走后灯灭），未发现传感器卡死、误报或长时间无响应导致的“异常不活跃”情况。"
  ],
  "key_evidence": [

    "2026-07-30T11:39:00 厨房灶具关闭时，厨房温度正常且有人在场，无烟雾报警器触发记录。",
    "连续三天（7/28-7/30）的卧室夜间占用模式一致，表明老人睡眠习惯稳定，无突发离家或跌倒后的长时间静止异常。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期检查烟雾报警器和漏水传感器的电池及功能，确保其处于最佳工作状态。"
