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
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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",

    "2. 行为关联：在门打开后的 20:04:00，玄关灯(entrance_light)被点亮，这是典型的‘回家’自动化场景或用户手动操作，表明有人进入了入户区域。",
    "3. 排除入侵特征：虽然日志中未直接显示 occupancy_sensor 的即时触发（可能因延迟或过滤），但结合门锁解锁、开门、开灯的连贯动作，且发生在晚间（20:00左右），符合居民日常作息规律，而非非法入侵（非法入侵通常伴随夜间静默或异常快速移动，且不会先合法解锁再开门）。"

## 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",

## 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: ...",

    "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行为，设备日志显示独居老人的日常作息规律且符合预期。",
  "reasoning": [
    "1. **作息模式一致性分析**：对比2026-07-31、08-01和08-02三天的数据，老人在早晨5:45-6:00左右起床（卧室/厨房活动传感器触发），随后在6:30-7:30之间离开家（入户门解锁并关闭，玄关无持续占用），并在晚上23:45-23:50左右返回（客厅活动传感器再次触发）。这三天的时间窗口高度一致，表明生活规律稳定。",
    "2. **关键操作逻辑验证**：在每天早晨离家前（如07-31 07:09, 08-01 06:53），均观察到厨房灯关闭（OnOff=False）以及入户门锁执行手动上锁操作（LockOperationType=0, Manual）。这符合“离家检查”的安全习惯，未发现未关火或忘带钥匙等风险迹象。虽然08-02早上灶具状态为False，但结合灯光关闭和出门动作，属于正常结束烹饪流程。",
    "3. **传感器数据合理性**：温度传感器读数随时间推移呈现合理的昼夜变化（夜间较低，白天因人体活动和日照逐渐升高），数值在23-25摄氏度范围内波动，无突变或无效值（除个别瞬间None外，随即恢复正常）。运动传感器在老人移动时正确触发，静止时归零，无长时间无响应（可能跌倒）或持续误报情况。"
  ],
  "key_evidence": [
    "连续三天早晨离家前均有 'kitchen_light OnOff = False' 和 'front_door_lock LockOperation(LockOperationType=0)' 记录，证明用户有主动关闭电器并反锁门窗的习惯。",
    "每日23:45-23:50 'living_room_occupancy = 1' 与早晨05:45-06:00的活动开始时间对应，确认了完整的睡眠-觉醒周期，排除了失踪或意外滞留户外的风险。",
    "各房间温度传感器读数平稳过渡，无异常高温（火灾风险）或低温（设备故障/极端天气影响）报警。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",

    "推理步骤 2: 结合 occupancy_sensor 数据，虽然厨房有人员活动记录（Occupancy=1），但时间跨度较长且温度上升速率过快（例如 06:41 到 06:50 仅 9 分钟升温近 2 度），这不符合正常做饭或短暂停留的热力学特征，更疑似设备故障、线路过热或潜在的阴燃火情初期。",
    "推理步骤 3: 尽管日志中未直接触发烟雾报警器报警（可能处于离线或未报告状态），但针对独居老人这一高风险群体，厨房温度的异常飙升是最高优先级的安全威胁，必须视为潜在的火灾前兆处理。"
  ],
  "key_evidence": [
    "2026-07-31T07:25:00 厨房温度传感器读数高达 2544 mK (25.44°C)，且此前数小时内呈持续上升趋势。",
    "2026-08-01T07:35:00 厨房温度再次飙升至 2528 mK，同时该时段厨房运动传感器显示有人在场，但无明确的灶具开启操作记录佐证如此高的温度。",
    "温度变化速率异常：在几分钟内温度上升幅度超过正常环境波动范围，且发生在清晨起床后的长时间活动中。"

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 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",

    "1. **时间模式分析**：日志主要覆盖 2026-07-20 至 2026-07-22 的清晨时段（05:00 - 08:30）。这是典型的家庭成员起床、洗漱和准备出门的时间段。",
    "2. **行为逻辑一致性**：\n   - **06:14 - 07:20 (主卧/主卫)**：主卧 occupancy 传感器在 06:14 激活，随后主卫灯光关闭（可能有人刚离开或调整），接着主卫 occupancy 在 06:46 和 07:11 再次激活，符合早起洗漱流程。\n   - **06:35 - 07:30 (儿童房/餐厅)**：儿童房 occupancy 在 06:35 后陆续激活，伴随灯光开启（06:37, 06:22等），表明孩子起床。餐厅灯在 07:21 和 07:26 开启，符合早餐时间。\n   - **07:20 (入户门)**：07:20 左右，前门接触传感器显示 False（关闭状态），门锁状态为 Locked (1)，且 07:19 有手动上锁事件。这通常意味着最后一名离家成员已确认关门并反锁，或者家人正在家中但检查了门锁，结合后续无入侵迹象，属于正常离家的收尾动作。",
    "3. **环境数据正常**：温度传感器读数随时间缓慢上升（从 ~24°C 升至 ~25°C），符合夜间散热后早晨室温回升的物理规律，无突变或传感器故障迹象。",
    "4. **无异常触发**：未检测到烟雾报警、漏水报警、非法开锁尝试或长时间无人居住时的异常活动。厨房灯在晚间（18:48）开启也符合晚餐准备习惯。"
  ],
  "key_evidence": [
    "连续三天清晨 06:00-07:30 期间，卧室、卫生间、客厅及餐厅的运动传感器按顺序激活，符合多人家庭起床动线。",
    "07:20 前后入户门锁处于锁定状态，且无非法解锁记录，符合离家或居家安全检查场景。",
    "温度传感器数值变化平缓（2438mK -> 2531mK），无跳变或停滞，排除传感器故障。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有自动化规则（如基于 occupancy 的灯光控制），以维持当前的舒适度和节能效果。"

## 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: ..."

    "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，所有设备活动符合正常的家庭作息规律。",
  "reasoning": [
    "1. **作息模式分析**：日志显示连续三天（7月23-25日）早晨6:00-7:30期间，主卧、儿童房和客厅的运动传感器依次被触发，伴随灯光开启和温度传感器读数变化。这符合典型的家庭成员起床、洗漱、准备早餐的晨间routine。",
    "2. **离家/归家逻辑一致**：7月23日和24日早上7:19-7:24左右，入户门传感器关闭且门锁执行手动上锁操作，同时运动传感器随后变为空闲（Occupancy=0），表明家庭成员正常出门上班或外出。7月23日晚22:10客厅有人活动，符合晚间居家状态。",
    "3. **无异常入侵迹象**：门锁仅在已知的时间段（早晨离家时）由Manual源触发上锁，没有非授权时间的开锁记录。门窗传感器在夜间保持关闭状态，无非法开启报警。",
    "4. **环境数据正常**：温度传感器读数随时间缓慢变化，符合室内热惯性特征，无突发性高温（火灾风险）或低温异常。厨房灶具和烟雾报警器在日志片段中未触发任何警报或异常高值。"
  ],
  "key_evidence": [
    "2026-07-23T07:19:30 和 2026-07-24T07:24:30 入户门锁 Manual Lock 操作与早晨离家时间吻合",
    "早晨时段 (06:00-07:30) 多个房间 occupancy 传感器按顺序激活，符合多人起床行为",
    "夜间及清晨无非法入侵或异常长时间无人后的突然活动"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续保持当前的自动化规则，如离家自动布防等。"
  ]
}
```

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到非正常时段（清晨）的入户门解锁及室内多房间活动，且伴随温度异常升高，疑似非法入侵或尾随进入。",
  "reasoning": [
    "时间异常：日志显示在 2026-07-23T07:19 和 2026-07-24T07:24 两个时间点发生了 front_door_contact (False) 和 front_door_lock (LockOperation)，结合上下文这些时间点处于住户通常起床后的活跃期之前或刚结束，但紧接着出现了多个房间的 occupancy 变化，需进一步确认是否为住户本人。然而，更关键的异常在于温度数据。",
    "温度漂移与传感器故障迹象：从 2026-07-23T05:00 到 08:00，living_room_temp_sensor 读数从 24.51°C 持续上升至 25.34°C（注意单位可能是 mK 或原始值，若为摄氏度则极热，若为毫开尔文则对应约 24.5°C，但趋势是上升的）。更重要的是，在 2026-07-24T06:37，kitchen_temp_sensor 报告了 None，随后读数波动剧烈。这种传感器数据的不一致可能意味着环境干扰或设备被物理接触/破坏。",
    "行为模式分析：在 2026-07-23T07:19 解锁后，master_bedroom_occupancy 变为 1，随后 kids_room_occupancy 也变为 1。而在 2026-07-24T07:24 解锁后，entrance_occupancy 变为 1，随后 dining_room 和 second_bedroom 也有活动记录。虽然这可能是住户早起，但考虑到 2026-07-25 全天所有房间 occupancy 均为 0 直到下午 06:41 才有人出现，这表明前两天的“清晨”活动模式与第三天的“完全空房”模式存在巨大反差。如果前两天是住户正常作息，第三天为何完全无人？这暗示前两天的日志可能存在伪造、传感器被篡改导致误报，或者是有人在非正常时间（如深夜至凌晨）进行了活动而未被正确识别为‘住户’，或者住户已离家但系统仍记录有活动（传感器故障）。",
    "综合判断：最可疑的点在于 2026-07-25 整日无活动（除了最后一点），而前两天有规律的清晨活动。如果住户习惯不变，第三天应同样有活动。这种‘突然消失’的活动模式强烈暗示前两天的活动记录不可信（可能是入侵者触发传感器但未留下其他痕迹，或是传感器被恶意干扰），或者住户已离开但门锁状态未同步更新。鉴于入户门被手动解锁这一关键事件发生在看似非典型的时间点（相对于第三天的完全静默），将其标记为潜在入侵风险最为稳妥。"
  ],
  "key_evidence": [
    "2026-07-23T07:19 和 2026-07-24T07:24 发生的 front_door_lock 手动解锁事件。",
    "2026-07-25 全天除傍晚外无任何 occupancy 活动，与前两天形成鲜明对比，暗示前两天数据异常或住户状态突变。",
    "厨房温度传感器在 2026-07-24T06:37 报告 None，随后数据波动，显示传感器可能受损或被干扰。"
  ],
  "recommended_actions": [
    "立即检查入户门锁的物理状态，确认是否有外部撬动痕迹或电池电量不足导致的自动上锁失败。",
    "联系住户核实过去两天的实际行踪，确认是否存在外出未通知的情况，或家中是否有人闯入。",
    "重置并校准所有温度传感器，特别是厨房和客厅的传感器，以排除因入侵导致的设备损坏或干扰。",
    "启用更严格的访问控制策略，例如要求每次开门通过手机 App 授权，并开启摄像头录像功能覆盖该时间段。"

## 任务
请从下面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，日志显示为独居老人在上午时段的正常居家活动。",
  "reasoning": [
    "1. 活动模式分析：日志时间集中在 08:25 至 10:35，符合老年人起床后的晨间活动时间窗口。客厅 occupancy 传感器在 08:40 和 09:00 等时间点多次触发（Occupancy=1），且伴随灯光开启（08:40, 10:07），表明住户在客厅有正常的起居活动。",
    "2. 多房间联动验证：除了客厅，卧室、厨房、玄关的 occupancy 传感器也分别在 09:15-10:35 期间多次触发，且温度传感器数据稳定（无剧烈跳变暗示设备故障）。这种跨房间的活跃状态符合老人在家中走动、查看情况或进行简单家务的行为特征。",
    "3. 门窗状态检查：重点关注的 bedroom_window_contact 和 living_room_window_contact 在 10:05-10:06 显示为 False（关闭/锁定状态）。结合室内温度传感器读数（约 25°C）和空调/窗户设备的常规逻辑，门窗关闭是正常的安全状态，未发现非法入侵迹象。",
    "4. 排除异常指标：没有发现烟雾报警、漏水报警或门锁异常操作。温度数据波动在合理范围内（24-25°C左右），属于环境自然变化或传感器正常误差，非传感器漂移或故障。"
  ],

    "bedroom_window_contact 和 living_room_window_contact 均保持 False (Closed) 状态，无非法开启记录。",
    "各房间温度传感器数值稳定，无极端值或突变，排除传感器故障。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控日常活动规律，若后续出现长时间无 occupancy 信号或门窗异常开启，再行介入。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "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": [
    "白天集中通风可能连续开窗，但通常伴随正常居家活动；异常样本发生在夜间。"

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。
