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",
  "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": "behavioral_anomaly",
  "threat_description": "出门频率突然下降",
  "reasoning": [
    "推理步骤1: 首日仍有出门链路",
    "推理步骤2: 后续明显缺少外出相关事件",
    "推理步骤3: 可能反映社交/功能退缩"
  ],
  "key_evidence": [
    "首日仍有出门链路",
    "后续明显缺少外出相关事件",
    "可能反映社交/功能退缩"
  ],
  "recommended_actions": [
    "标记为出门频率异常下降，建议结合老人状态持续观察。"
  ]
}

```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稳定，出入时间规律，设备状态符合正常生活逻辑，未发现安全威胁。",
  "reasoning": [
    "推理步骤 1: 分析入户门锁 (front_door_lock) 和门传感器 (front_door_contact) 的状态。日志显示每天早晨约 08:24-09:00 之间门锁解锁 (State=2) 且门打开 (Contact=False)，随后老人进入室内；晚上约 20:36-20:45 之间门锁重新上锁 (State=1)。这一模式在三天内高度一致，符合独居老人正常的作息习惯。",
    "推理步骤 2: 检查跨房间的活动连贯性。当玄关 (entrance) 检测到有人时，紧接着卧室 (bedroom) 或客厅 (living_room) 的占用传感器也会变为活跃状态，且温度传感器读数随人员活动有合理的波动（例如从夜间低温回升至日间舒适温度），表明是真实的人员移动而非传感器故障。",
    "推理步骤 3: 验证关键安全设备状态。厨房烟雾报警器、漏水传感器等未在日志中触发报警事件，且厨房灶具 (cook_surface) 仅在白天有人活动时出现温度变化，无异常高温或长时间无人看管烹饪的迹象。所有设备行为均在预期范围内。"
  ],
  "key_evidence": [
    "front_door_lock 在每日固定时间段（~08:30 出门，~20:40 回家）呈现规律的解锁/上锁循环。",
    "bedroom_occupancy 和 living_room_occupancy 的状态变化与 front_door_contact 的变化存在合理的时间延迟和空间逻辑关联，排除了入侵可能。",
    "temperature_sensor 数据反映了昼夜温差和人员活动带来的热效应，曲线平滑自然，无突变或漂移现象。"
  ],
  "recommended_actions": [
    "继续保持当前的监控频率，无需额外干预。",
    "建议定期检查门锁电池电量，确保其能支持完整的开合周期记录。",
    "鉴于住户为独居老人，可考虑在现有基础上增加一次每周的视频通话确认，作为非技术性的双重保障。"

## 任务
请从下面 2 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": [

    "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。

  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "做饭时间异常短",
  "reasoning": [

  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式正常，设备运行状态符合预期，未发现安全威胁或异常行为。",
  "reasoning": [
    "时间序列分析：厨房灶具 (kitchen_cook_surface) 的开启与关闭事件（如 12:00-12:05, 16:52, 10:54-11:00, 12:00-12:04）均伴随厨房运动传感器 (kitchen_occupancy) 的活跃信号，且持续时间短（通常<5分钟），符合老人短时间烹饪或检查的习惯，无长时间无人看管烹饪迹象。",
    "环境数据合理性：温度传感器读数（如 living_room_temp_sensor 的 2535-2548 mK，即约 25.3-25.5°C）处于舒适且正常的室温范围，数值波动平稳，无传感器漂移、卡死或突变现象；卧室温度略低也符合夜间/休息时段特征。",
    " occupancy 逻辑一致：各房间的运动传感器状态变化与光照、窗帘等执行器动作逻辑自洽（例如 12:29 关灯并拉上卧室窗帘，随后卧室占用检测持续存在直至下午，符合老人午休场景），未见入侵者闯入导致的异常跨房间快速移动或门锁异常开启记录。"
  ],
  "key_evidence": [
    "厨房灶具操作均有对应的现场人员活动记录，且单次操作时间短，未出现‘灶具开启后长时间无人’的 unattended_cooking 模式。",
    "所有温度传感器读数稳定在合理区间（~25°C），无 sensor_drift 或 sensor_malfunction 特征。",
    "卧室窗帘关闭与灯光熄灭的时间点吻合，且后续有持续的占用检测，表明是住户自主行为而非外部干扰。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期复核 Matter 协议下传感器校准状态，确保长期数据准确性。"

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": [

    "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": "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"
  ],
  "key_evidence": [
    "深夜在非卧室区域持续活动",
    "时长明显超出普通起夜",
    "可能是迷路或意识混乱"
  ],
  "recommended_actions": [

  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到厨房区域在无人状态下出现持续高温且伴随灯光开启，存在严重的火灾隐患。",
  "reasoning": [
    "时间异常：日志显示时间为凌晨 02:10 至 04:10，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，确认屋内无人。",
    "温度异常：厨房温度传感器读数从 02:10 的 23.7°C (2370mK) 持续攀升至 04:10 的 24.08°C (2408mK)，并在短时间内达到极高值（如 03:50 达到 2402mK ≈ 24.02°C），对于独居老人家庭，夜间厨房长时间高温极不寻常。",
    "行为矛盾：在 02:50 时，厨房灯光 (kitchen_light) 被意外开启 (OnOff.OnOff = True)。在无人且无其他活动迹象的情况下，灯光自动开启并伴随温度急剧升高，强烈暗示灶具可能处于未关闭的加热状态或发生了电气故障。",
    "风险累积：虽然烟雾报警器尚未触发（可能是阈值未到或设备延迟），但温度的持续上升趋势和无人看管的状态构成了明确的火灾前兆风险。"
  ],
  "key_evidence": [
    "02:10 - 04:10 期间所有房间 occupancy 均为 0，确认无人。",
    "02:50 kitchen_light 状态变为 True，但在无人情况下非正常开启。",
    "厨房温度从 23.7°C 持续上升至 24.08°C，且数值波动剧烈，不符合自然散热规律。",
    "事件发生在深夜凌晨，属于高风险时段。"
  ],
  "recommended_actions": [
    "立即远程通知住户或其紧急联系人，告知厨房可能存在火情隐患。",
    "尝试通过 Matter 协议远程关闭厨房灯光及疑似异常的灶具/电器（如果权限允许）。",
    "检查厨房烟雾报警器和温度传感器的校准状态，排除传感器漂移导致的误报（尽管概率较低，因多传感器数据趋势一致）。",
    "建议物业或家属上门检查厨房电路及灶具安全状况。"
  ]
}

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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "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"
  ],

  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到厨房区域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，此时独居老人通常处于睡眠状态（符合跨天摘要中 bedroom/living_room occupancy=0 的模式），属于非活跃时段。",
    "推理步骤 2: 占用状态与温度关联分析。从 02:10 开始，kitchen_occupancy 传感器短暂报 1（可能是宠物、老鼠或误报），随后在 02:30 及之后长时间保持为 0（无人）。然而，在此期间，kitchen_temp_sensor 读数从 23.4°C (2340 mK) 持续攀升至 24.1°C (2416 mK)，并在最后阶段达到 24.12°C。",
    "推理步骤 3: 异常模式识别。对于独居老人家庭，凌晨时段厨房无人但温度持续显著上升（超过正常室温波动范围，接近或超过人体体温/发热物体温度）是典型的火灾前兆特征。这种‘无人 + 升温’的组合排除了正常烹饪行为，极有可能是电器故障起火初期或隐蔽火源导致的温升。",
    "推理步骤 4: 设备类型确认。日志中包含 'kitchen_cook_surface'（灶具），虽然未直接上报 OnOff=True，但温度的异常轨迹强烈暗示灶具或其他热源失控。"
  ],
  "key_evidence": [
    "02:30 至 04:20 期间 kitchen_occupancy 持续为 0（无人），但 kitchen_temp_sensor 温度从 23.4°C 持续上升至 24.1°C。",
    "温度上升趋势陡峭且无下降迹象，不符合自然散热规律，符合热积累特征。",
    "事件发生在凌晨深夜，住户处于睡眠状态，无法及时察觉物理火情。"
  ],
  "recommended_actions": [
    "立即触发全屋烟雾报警器测试或远程通知物业/消防部门进行核查。",
    "通过 Matter 协议向厨房空调发送强制开启指令（若连接）以尝试降温，并关闭厨房非必要电源（若具备控制能力）。",
    "联系家属或紧急联系人，告知潜在风险并要求其前往查看或协助处理。",
    "检查厨房灶具及周围电器是否存在过热损坏或线路老化问题。"

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",
  "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": "独居老人在凌晨2:10至3:00期间于厨房出现异常活动，且随后长时间无其他房间活动记录，存在跌倒或突发疾病未获救助的风险。",
  "reasoning": [
    "1. 识别异常时间窗口：日志显示在 2026-07-01 凌晨 02:10 至 03:00 之间，厨房运动传感器 (kitchen_occupancy) 检测到有人（值为1），且厨房灯在 02:50 开启。对于独居老人而言，深夜起床活动本身属于非典型行为，需警惕健康原因。",
    "2. 分析环境数据异常：在此期间，客厅温度传感器读数从约 23.4°C 持续上升至 24.0°C+，厨房温度也升至 23.9°C。虽然可能是空调关闭或门窗问题，但结合深夜无人居住的背景，这种局部升温可能暗示设备故障或通风异常，增加了不适感。",
    "3. 评估后续静默风险：03:00 后，所有房间的运动传感器均报告为 0（无人），直到日志结束（04:10）。考虑到老人已在厨房活动并开灯，若之后没有去卧室睡觉或离开房屋，而是停留在厨房或附近区域失去响应，极有可能是发生了跌倒、昏迷或其他紧急医疗状况，导致无法触发运动传感器或移动。",
    "4. 排除正常干扰：虽然深夜活动可能是口渴或起夜，但在缺乏后续“返回卧室”或“再次活动”证据的情况下，必须将其视为高风险的健康安全隐患，而非简单的行为习惯。"

    "推理步骤 2: 温度异常检测。厨房温度传感器读数从 02:10 的约 23.3°C (2330mK) 持续攀升，至 03:55 达到峰值约 24.0°C (2402mK)，并在后续时间点维持在极高水平。对于无人居住的厨房，这种持续数小时的显著升温不符合正常散热规律，强烈暗示有热源（如灶具未关或电器故障）在工作。",
    "推理步骤 3: 设备状态关联。在温度急剧上升期间（02:50），厨房灯光被打开 (OnOff.OnOff = True)。虽然灯光本身产生热量有限，但在无人监控的情况下，灯光开启可能意味着有人误操作或系统自动触发，结合持续的高温，进一步证实了厨房内存在非正常的能源消耗和热积聚现象，构成严重的火灾隐患。"
