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",
    "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。

Chosen response:

  "threat_type": "behavioral_anomaly",
  "threat_description": "出门频率突然下降",
  "reasoning": [

  ]
}

Rejected response:
```json
{

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式稳定，无入侵、设备故障或环境安全隐患。",
  "reasoning": [
    "入住与出门逻辑正常：住户在早晨（约 07:26-08:14）从卧室起床并进入客厅/厨房活动，随后在 09:00 左右前门接触传感器触发且门锁状态变为'Unlocked'（值 2），紧接着玄关和客厅有人，符合老人自然起床开门出门的时序；次日 08:37 也有手动解锁记录，但随后立即检测到室内有人，表明是住户返回家中而非外人闯入。",
    "跨天行为一致性高：三天内的房间占用计数（living_room~210, bedroom~240, kitchen~238）高度一致，且温度传感器读数均在合理范围（25°C 左右，对应日志中的 25xx 毫伏值），未出现异常高温或低温漂移。",
    "关键安全设备工作正常：烟雾报警器、漏水传感器等未在日志中报告报警事件；门锁操作有明确的'Manual'来源标记，且前后均有合法的室内人员活动轨迹支撑，排除了尾随或非法入侵的可能性。"
  ],
  "key_evidence": [
    "2026-08-08T09:00:00 front_door_contact (False) 后紧随 09:01:00 lock_unlock 及室内人员活动，符合住户出门场景。",
    "2026-08-10T08:37:00 门锁手动解锁后，08:37:02 即检测到 living_room_occupancy=1，证明是住户返回而非陌生人进入。",

  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",

## 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。

Chosen response:
{
  "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3: 提示功能退化或健康问题"
  ],

    "跨天持续出现",
    "提示功能退化或健康问题"
  ],

  ]
}

Rejected response:
```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": [
    "时间线分析：所有事件均发生在合理的起床（07:00-08:30）、早餐/厨房活动（08:30-10:00）和日间活动时段，符合独居老人的典型作息规律。",
    "空间逻辑验证：运动传感器触发顺序合理（入户门 -> 玄关 -> 客厅/厨房），且卧室在夜间（00:00-06:59）保持无人状态，排除了非法入侵或异常滞留的可能性。",
    "环境数据校验：温度传感器读数（约 24.5°C - 25.5°C）处于舒适且安全的范围内，未出现烟雾报警器误报或高温预警；虽然 07-23 厨房传感器曾短暂丢失数据，但随后立即恢复并记录正常数值，属于瞬时通信波动而非持续故障。",
    "行为一致性：老人每日活动轨迹高度一致，未见长时间静止不动（排除跌倒风险）或深夜异常移动等危险信号。"
  ],
  "key_evidence": [
    "连续三天（07-21 至 07-23）的起床时间和厨房活动时间窗高度重合，表明生活规律稳定。",
    "夜间（00:00 至次日 07:00）所有房间 occupancy 均为 0，且无任何非预期开门事件。",
    "温度传感器读数稳定在 24-26 摄氏度区间，无火灾前兆的高温异常。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期检查厨房漏水传感器和烟雾报警器的电池状态，确保长期可靠性。",
    "鉴于老人独居，可考虑在现有基础上增加每周一次的远程健康问候或视频通话确认。"

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。

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。

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",
  "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。

  "threat_description": "夜间长期停留在非卧室区域",
  "reasoning": [
    "推理步骤1: 深夜在非卧室区域持续活动",
    "推理步骤2: 时长明显超出普通起夜",
    "推理步骤3: 可能是迷路或意识混乱"
  ],

  ],

Rejected response:

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房在无人状态下出现持续高温且温度异常升高，存在严重的火灾隐患。",
  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:20，此时所有房间（包括客厅、卧室、卫生间、玄关）的运动传感器均报告 Occupancy = 0，确认家中无人在场。",
    "推理步骤 2: 设备状态异常。尽管厨房运动传感器在大部分时间报告为 0，但在 02:35 和 02:50 短暂检测到有人（Occupancy=1），随后又变为 0。然而，厨房温度传感器读数从 02:10 的 23.27°C (2327mK) 开始持续攀升，至 04:20 达到 24.12°C (2412mK)，升温速率极快且幅度巨大。",
    "推理步骤 3: 关联风险判断。对于独居老人家庭，夜间无人时厨房温度异常飙升通常意味着灶具（cook_surface）可能处于开启状态但未被察觉，或者发生了其他热源故障。考虑到温度已超过正常室温并持续上升，这构成了极高的火灾风险（unattended cooking leading to fire risk）。"
  ],
  "key_evidence": [
    "02:10 - 04:20 期间，除厨房外所有区域 occupancy 均为 0，表明无人看管。",
    "厨房温度从 02:10 的 23.27°C 急剧上升至 04:20 的 24.12°C，且在无人状态下持续升温。",
    "厨房灯光在 02:50 被打开，但随后在 03:00 及之后未再关闭或有人离开迹象，暗示可能存在操作失误或设备失控。"
  ],
  "recommended_actions": [
    "立即远程切断厨房电源或关闭智能灶具，防止火势蔓延。",
    "向住户发送紧急警报通知其回家检查厨房情况。",
    "联系当地消防部门进行预防性检查（如果系统支持自动报警联动）。",
    "检查厨房烟雾报警器是否正常工作，确保其能发出声音警报。"

System:
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",
  "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。

  "threat_description": "检测到厨房区域在无人状态下出现异常高温持续上升，且伴随灯光开启，存在极高的火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:20，此时独居老人通常处于睡眠状态（卧室温度稳定在 22°C 左右，而客厅/厨房温度显著升高），所有房间的运动传感器均报告 Occupancy = 0，确认屋内无人。",
    "推理步骤 2: 温度异常模式识别。厨房温度传感器读数从 02:10 的 23.4°C (2340 mK) 开始，呈现持续且快速的上升趋势，至 04:00 达到峰值 24.1°C (2410 mK)，温差超过 0.7°C。这种在无人员活动的情况下，特定房间温度持续攀升的现象不符合正常散热规律，强烈暗示有热源产生。",
    "推理步骤 3: 关联设备行为验证。在温度急剧上升期间（02:50），厨房灯光被意外开启 (OnOff.OnOff = True)。虽然灯光本身发热量不足以导致如此高的温升，但这可能是自动联动或误操作的结果，进一步佐证了该区域存在非正常的电气活动或设备故障（如灶具未关、烤箱过热等）。考虑到是独居老人家庭，夜间无人看管下的热源失控属于最高优先级的火灾隐患。"
