## 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": "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10:30-14:00期间活跃，涉及客厅、厨房、卧室和玄关的频繁移动（Occupancy传感器持续触发），符合老年人白天起床后在主要生活区域活动的习惯。",
    "2. 关键设备行为：厨房灯（kitchen_light）仅在中午时段（12:05, 12:35, 12:15）开启，这与午餐准备或用餐时间高度吻合，未发现深夜或长时间无人时的异常亮灯，排除了遗忘关闭或误操作的风险。",
    "3. 环境数据合理性：温度传感器读数（如2500-2550代表25.0-25.5°C）处于舒适区间，且随时间缓慢变化，无剧烈跳变，表明传感器工作正常，无漂移或故障迹象。",
    "4. 安全性检查：未检测到烟雾报警器触发、漏水传感器报警或门锁异常开启记录。入户门传感器虽有触发，但结合室内人员活动轨迹，属于正常的进出或内部移动，无入侵特征。"
  ],
  "key_evidence": [
    "厨房灯仅在12:00-13:00左右开启，符合午餐时段习惯。",
    "多房间运动传感器在白天持续有信号，证明老人处于清醒和活动状态，无跌倒或长时间静止风险。",
    "温度读数稳定在24-26°C之间，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长期数据准确性。"
  ]
}
```

{
  "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。"
  ]

## 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，环境参数正常。",
  "reasoning": [
    "1. 门窗状态分析：重点关注的入户门传感器 (front_door_contact) 在三天内均报告为 False（关闭/锁定）。虽然日志中缺少 'Open' 事件，但这符合独居老人在家期间门窗保持关闭的常态，且没有伴随异常的入侵报警或多次尝试开锁记录，属于正常静态状态。",
    "2. 人员活动模式分析： occupancy_sensor（运动传感器）在客厅、厨房、卧室等区域频繁触发，表明住户在白天有正常的居家活动轨迹。例如8月19日和20日早晨，玄关和厨房均有活动迹象，随后客厅持续有人，符合老人起床后在家活动的习惯。",
    "3. 环境与设备状态分析：温度传感器读数稳定（约24-25°C），无剧烈波动；烟雾报警器、漏水传感器无任何告警触发；灶具仅在8月20日上午短暂开启并随后关闭，未见长时间无人看管烹饪的迹象。",
    "4. 综合判断：所有关键安全设备（门锁、烟感、水浸）无异常触发，住户活动符合日常规律，无跌倒、长时间静止或非法入侵迹象。"
  ],
  "key_evidence": [
    "front_door_contact 连续多日保持 False (Closed)，无异常开启记录",
    "occupancy_sensor 在 living_room, kitchen, bedroom 呈现规律的日间活动模式",
    "smoke_co_alarm 和 water_leak_detector 全程无告警事件",
    "kitchen_cook_surface 仅短暂开启一次，无超时未关风险"
  ],
  "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（虽目前看起来正常）"
  ]
}
```

{
  "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。

## 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: ..."
  ],

    "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。"
  ],

  ]
}

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "health_concern",
  "threat_description": "独居老人在凌晨时段（02:18 - 05:38）出现长时间无活动且卧室灯光异常开启，随后在清晨再次开灯，存在夜间跌倒、突发疾病或被困风险。",
  "reasoning": [
    "推理步骤 1: 时间窗口分析。日志显示在 02:10 至 05:38 之间，所有房间（living_room, bedroom, kitchen, bathroom, entrance）的 OccupancySensing.Occupancy 持续为 0，表明屋内无人移动超过 3.5 小时。对于独居老人而言，这是极不正常的静默期。",
    "推理步骤 2: 行为逻辑矛盾。在 02:18，bedroom_light 被打开（OnOff.OnOff = True），但此时 occupancy_sensor 仍报告为 0。通常人进入房间会触发传感器，或者人离开后灯会自动关闭/延时关闭。这种‘灯亮但无人’的状态可能意味着：(a) 老人跌倒在地无法起身触发传感器；(b) 老人意识不清操作了开关；(c) 传感器故障未检测到人体。",
    "推理步骤 3: 后续状态确认。直到 05:38 才再次有 bedrooom_light 开启事件，中间长达 3 小时无任何 occupancy 变化或设备交互。结合独居老人的背景，长时间静止伴随异常的灯光操作，高度疑似健康危机（如中风、心脏病发作导致倒地）或意外跌倒。",
    "推理步骤 4: 排除其他威胁。厨房灶具、烟雾报警器、漏水传感器均无异常报警记录，温度读数虽有波动但在合理范围内（约 22-24°C），排除了火灾、煤气泄漏或水管爆裂等物理环境威胁。"
  ],
  "key_evidence": [
    "02:18 至 05:38 期间，全屋运动传感器持续报告 Occupancy=0，形成超 3 小时的静默期。",
    "02:18 和 05:38 两次出现 bedroom_light 开启事件，但两次开启之间及第一次开启时均无对应的人员移动检测信号。",
    "跨天摘要显示该时间段内各房间活动量极低（bathroom=61 次，远低于白天水平），印证了夜间活动的缺失。"
  ],
  "recommended_actions": [
    "立即通过家庭监控摄像头查看卧室及客厅画面，确认老人位置及状态。",
    "尝试远程联系老人或其紧急联系人，询问情况。",
    "若联系不上且视频确认异常，立即拨打急救电话并通知家属。",
    "检查卧室运动传感器是否因遮挡或故障导致误报，必要时进行校准或临时移除障碍物。"

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

  "threat_description": "未检测到安全威胁，设备状态和住户活动模式符合独居老人的正常生活规律。",
  "reasoning": [
    "1. 活动模式分析：日志显示住户在早晨7:00-9:00期间活跃（厨房、客厅、卧室均有 occupancy 记录），随后活动减少，夜间23:46-23:50仍有活动记录，符合老年人早起晚睡或作息规律的常态，未发现长时间无活动的健康风险（abnormal_inactivity）。",
    "2. 门锁与入侵检查：三天内仅在早晨8:27、8:34、8:34左右出现手动开锁记录（Manual Lock Operation），且伴随玄关/入户门运动传感器触发，这符合住户出门或回家的正常行为。未检测到非授权时间的非法闯入或异常锁操作。",
    "3. 环境安全监控：虽然日志中主要展示了温度读数（如2509即25.09°C）和占用情况，但未出现烟雾报警器（smoke_co_alarm）或漏水传感器（water_leak_detector）的报警事件。厨房灶具（cook_surface）虽在厨房有人时存在，但无异常高温或持续无人看管的证据（通常需结合灶具状态和长时间无移动判断，此处仅展示占用，且时间较短，属正常烹饪时段）。",
    "4. 传感器状态：温度读数随时间缓慢变化，符合室内热惯性特征；占用传感器在人员移动时正确触发，无明显的卡死（stuck）或漂移（drift）迹象。"
  ],
  "key_evidence": [
    "连续三天早晨8:30左右的手动开锁记录与玄关运动传感器联动，符合正常出行习惯。",
    "全天各房间占用传感器交替触发，无超过24小时的完全静止区域（除睡眠时段外），排除跌倒或昏迷风险。",
    "无烟雾、一氧化碳或漏水报警事件记录。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需紧急干预。",
    "建议定期校准温度传感器以确保读数准确性，尽管目前数据看起来正常。"

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 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",
  "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。"
  ]
