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",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [

    "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模式稳定且符合预期。",

    "1. 门锁状态分析：8月11日06:54记录了一次手动开锁（LockOperationType=0），随后在08:05和08:39分别记录了锁状态为1（锁定）和2（已上锁/反锁）。这符合老人早晨起床、出门买菜或散步后返回并重新锁门的正常行为逻辑。8月12日20:35再次记录锁状态为1，符合晚间回家锁门的习惯。",
    "2. 人员活动轨迹分析：运动传感器数据显示，老人在客厅(living_room)的活动最为频繁，这与‘重点房间’设定及老人居家习惯一致。卧室(bedroom)和厨房(kitchen)也有规律的活动记录，卫生间(bathroom)活动较少但存在，整体动线合理，无长时间静止导致的异常静默报警触发迹象。",
    "3. 环境数据一致性：温度传感器读数随时间变化呈现自然波动（如夜间降温、白天升温），数值在合理范围内（约22-25摄氏度），未发现传感器故障或漂移导致的极端值。烟雾报警器和水浸传感器在整个日志期间无任何触发事件，排除了火灾和水患风险。",
    "4. 跨天模式对比：三天的活动摘要数据显示各区域活跃度基本持平，没有突发的剧烈变化或长期缺失，表明住户生活规律稳定，无突发健康危机或失踪迹象。"
  ],
  "key_evidence": [
    "front_door_lock在06:54出现Manual开锁，随后在08:05/08:39变为锁定状态，符合晨间外出归家模式。",
    "living_room_occupancy在三天内持续有高频活动记录，证明住户处于活跃状态。",
    "所有安全类传感器（烟雾、水浸）在日志期间无告警事件。",
    "温度数据变化平缓，符合昼夜温差规律，无设备故障特征。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",
    "建议定期校准门窗传感器以确保状态反馈准确，尽管目前看来工作正常。"
  ]
}
```

{
  "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": [
    "正常样本是每天傍晚回家时间略有波动；异常样本是在固定下午时点出现活动。"

## 任务
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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": "未检测到安全风险，日志显示为正常的晚间回家及居家活动模式。",
  "reasoning": [
    "1. 时间与环境分析：事件发生在2026-08-28的傍晚至夜间（17:34 - 18:43），属于典型的下班回家时间段。此时段室内运动传感器（客厅、主卧、次卧）此前均显示无人（Occupancy=0），符合家庭成员外出工作的状态。",
    "2. 入户行为逻辑验证：18:09分，门锁执行上锁操作（LockState=2），随后门磁显示关闭（False）。紧接着玄关灯亮起，且约10秒后客厅运动传感器检测到有人（Occupancy=1），同时客厅灯光和空调开启。这一序列（开门/进门 -> 亮灯 -> 激活生活区设备）完全符合住户正常回家的行为逻辑。",
    "3. 持续活动与二次确认：18:19至18:43期间，玄关和客厅的运动传感器持续报告有人存在，表明住户在屋内停留并进行日常活动。18:40分的门锁状态再次确认为锁定（LockState=2），可能是住户在屋内移动触发了自动上锁功能或手动检查，结合后续的灯光和传感器活跃状态，无异常闯入或滞留迹象。"
  ],
  "key_evidence": [
    "18:09:00 门锁上锁 (LockState=2) 后，18:09:18 客厅 occupancy 变为 1，且伴随灯光和空调开启，构成完整的回家行为链。",
    "18:19:00 - 18:43:00 期间，entrance_occupancy 和 living_room_occupancy 持续为 1，证明住户在室内正常活动，无长时间静止或异常离开。",
    "所有关键设备（门锁、门磁、运动传感器、灯光、空调）的状态变化时序合理，无冲突或矛盾数据。"
  ],
  "recommended_actions": [
    "无需采取任何安全措施。",
    "建议继续保持当前的自动化规则，以优化居住体验。"
  ]
}
```

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",

  ],
  "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。

  "confidence": "high",

  "reasoning": [
    "1. 时间分析：事件发生在2026-08-12的傍晚至晚上（17:32 - 18:43），符合典型的下班回家时间段。",
    "2. 行为序列分析：用户在17:32进入玄关（occupancy=1），随后在18:23手动解锁并打开入户门（LockState从2变为1，Contact从False变为True）。这一系列动作表明用户正在进入家中。",
    "3. 后续活动验证：进门后，玄关灯亮起（18:23），客厅 occupancy 传感器检测到人员活动（18:23），且空调开启、主灯点亮。这构成了完整的‘回家’逻辑链：开门 -> 进屋 -> 开灯/开空调。",
    "4. 排除异常：虽然日志中出现了两次门锁状态变化（17:32和18:23），但结合上下文，17:32可能是之前的记录或误触，而18:23的动作伴随了室内灯光和人员的联动响应，符合正常住户回家的特征。没有发现强行闯入、长时间未关门或无人却开灯等可疑迹象。"

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。

    "3. **人员活动轨迹**：客厅运动传感器在 17:50 至 19:40 期间持续报告有人（Occupancy=1），卧室和卫生间传感器也有间歇性活动记录。这表明住户一直在家中活动，没有长时间静止不动导致的跌倒或健康异常风险，也没有长时间离家导致的空屋风险。",

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",
  "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。

    "1. 门锁与入户行为分析：7月13日07:24和18:08、7月14日18:05均记录到前门手动解锁（LockOperationType=1）及随后玄关灯亮起、空调开启或 occupancy 传感器激活。这构成了典型的‘离家-回家’闭环逻辑，且时间（早晨出门/晚上回家）符合常规作息，无异常时段（如深夜）的门禁触发。",
    "2. 室内活动一致性：客厅运动传感器（living_room_occupancy）在晚间（18:10后）持续报告有人（Occupancy=1），并在次日凌晨00:00变为无人（Occupancy=0）。这种从傍晚活跃到深夜静止的模式符合正常的居家休息习惯，排除了非法入侵后长时间滞留或异常离开的情况。",
    "3. 环境数据合理性：温度传感器读数随时间变化呈现自然波动（如白天升温、夜间降温），且厨房温度在晚间烹饪时段（18:20-18:30）有显著上升（2642->2711），随后恢复，这与使用灶具的行为一致，未触发烟雾报警器，表明烹饪过程安全可控。"
  ],
  "key_evidence": [
    "7月13日 07:24 前门手动解锁，随后07:26卫生间传感器短暂激活（可能为晨间洗漱），符合早晨离家前的活动。",

    "7月13日 00:00 至 7月14日 16:20 期间，主要生活区域（客厅） occupancy 为0，仅偶发卫生间活动，符合夜间睡眠及白天外出状态。",
    "7月13日 18:20-18:30 厨房温度快速升高，伴随厨房灯开启，确认为正常烹饪行为，无火灾报警。"
  ],
  "recommended_actions": [

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
请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

请按以下 JSON 格式回答：

```json

  "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",

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。
