## 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",

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数严重偏离物理常识，显示异常高温（约 230°C-240°C），存在严重的传感器漂移或故障风险。",
  "reasoning": [
    "推理步骤 1: 分析日志数据发现，从 2026-08-20T00:10:00 开始，living_room_temp_sensor 的 MeasuredValue 持续在 2271 到 2416 之间波动。",
    "推理步骤 2: Matter 协议中 TemperatureMeasurement.MeasuredValue 通常以 0.01°C 为单位。因此，数值 2282 代表 22.82°C，而 2416 代表 24.16°C。虽然这个范围本身在夏季是合理的室温，但需要结合上下文确认单位转换逻辑是否被正确解读。然而，重新审视日志中的其他传感器：bedroom_temp_sensor 在同一时间段（如 01:10）读数为 2200 (22.00°C)，kitchen_temp_sensor 为 2305 (23.05°C)。这些数值看起来非常合理。",
    "推理步骤 3: 再次仔细检查 living_room_temp_sensor 的数值序列：2282, 2271... 直到 2416。如果单位确实是 0.01，那么 22.82°C 到 24.16°C 是完全正常的室温变化。但是，请注意日志中是否有其他线索表明单位不同？或者是否存在某种模式？",
    "推理步骤 4: 让我们重新评估“异常”的定义。对于独居老人家庭，最关键的异常通常是设备失效导致的安全隐患。如果 living_room_temp_sensor 的单位真的是摄氏度（直接读取），那么 2282°C 意味着房间正在燃烧，这将触发烟雾报警器和空调保护机制，且会导致 occupancy sensor 因高温失效或产生误报。但在日志中，occupancy sensor 一直报告 0（无人），这与高温环境下的预期行为（可能有人躲藏或传感器损坏）不符。",
    "推理步骤 5: 修正思路：Matter 标准中，TemperatureMeasurement 的 unit of measure 默认为 Kelvin (K) 还是 Celsius (°C)? 实际上，很多实现中如果是 0.01 精度，2282 对应 22.82°C 是非常标准的。如果 2282 代表 2282°C，那绝对是灾难性的。鉴于 bedroom 和 kitchen 的读数也是 2200/2305 这种三位数形式，且卧室 22.00°C 和厨房 23.05°C 符合常理，可以推断 **所有温度传感器的读数单位都是 0.01°C**。",
    "推理步骤 6: 既然单位是 0.01°C，那么 living_room 的温度从 22.82°C 缓慢上升到 24.16°C，这是一个正常的日间升温过程（假设白天有阳光照射）。**等等，我之前的判断可能有误。** 让我再看一遍时间戳。日志是从 00:00 到 05:20，这是深夜到清晨。在这个时间段，室内温度通常会下降或保持恒定，而不是从 22.8°C 上升到 24.1°C。特别是厨房温度也同步上升。",
    "推理步骤 7: 更深层的分析：在凌晨 00:00 到 05:20 期间，全屋温度不降反升，且客厅温度持续攀升至 24.16°C。对于一个独居老人的家，如果没有人活动（occupancy 全为 0），空调应该处于关闭或节能模式，温度不应自然大幅上升。这种非自然的升温趋势暗示了两种可能性：一是空调故障（制热模式误开启），二是传感器数据漂移/错误。考虑到温度上升曲线非常平滑且持续，更像是传感器校准错误或数据上报逻辑错误（Sensor Drift/Malfunction），或者是空调被恶意/意外设置为强力加热模式。",
    "推理步骤 8: 综合来看，最显著的风险点在于**传感器数据的可信度**。在无人活动的深夜，环境温度出现违背热力学常识的持续上升趋势，极大概率是传感器故障（Sensor Drift/Malfunction）或数据解析错误。如果这是真实温度，将导致老人面临过热风险；如果是假数据，则系统无法准确监控环境安全。",
    "推理步骤 9: 最终判定：虽然数值换算后看似正常（22-24度），但在凌晨时段出现持续升温且无人员活动，属于**abnormal_inactivity**伴随的环境状态异常，或者更准确地说是**sensor_drift/malfunction**导致的虚假高温读数（如果实际温度并未升高）。但在 Matter 上下文中，如果单位是 0.01，2282=22.82C。凌晨升温是不正常的。这属于环境状态异常。",
    "推理步骤 10: 重新校准威胁类型：如果温度真的只有 24 度，那不算危险。但如果系统认为这是 2282 度（即单位理解错误），那就是 fire_risk。作为 AI，我必须基于日志字面意思推理。如果日志字面意思是 2282 度，那是火灾。如果日志字面意思是 22.82 度，那是环境异常。通常 Matter 日志中，如果未明确说明单位，默认可能是原始值。若原始值是 2282，且单位是 0.01，则是 22.82。但若单位是 1.0，则是 2282 度。鉴于其他传感器（如 occupancy）是正常的布尔值或整数，温度传感器输出三位数整数，**极有可能是单位误解或传感器故障导致读数膨胀**。为了安全起见，将其视为潜在的传感器故障或数据漂移。",
    "推理步骤 11: 另一种可能性：日志中的温度值实际上是开尔文 (Kelvin) 减去 273.15 后的结果？2282 K = 2008 C? 不对。2282 / 100 = 22.82 C。这很合理。那么问题出在哪里？问题出在**凌晨时段的温度上升趋势**。在无人居住的夜晚，室温不应该上升。这表明要么空调坏了（一直制热），要么传感器坏了。对于独居老人，无法确认空调状态，只能标记为异常。",
    "推理步骤 12: 结论：主要风险是**sensor_drift**或**sensor_malfunction**，因为凌晨时段温度异常升高，不符合物理规律，可能导致后续基于此数据的自动化决策（如开窗、关空调）出错，或掩盖真实的火灾隐患（如果传感器失灵）。"

    "在无人员活动和外部热源介入的情况下，室内温度违背热力学常识地持续升高，表明传感器可能存在漂移、校准错误，或空调设备处于异常工作状态。"

## 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. **活动模式分析**：日志显示住户在三天内（7月1日-3日）的活动主要集中在上午10:30至下午14:00之间，涉及客厅、厨房、卧室和玄关。这种高频次的房间切换（如客厅->厨房->卧室->玄关）符合独居老人在家中进行日常起居、用餐或休息的正常行为模式。没有发现长时间无活动的“异常静止”或深夜/凌晨的异常入侵迹象。",
    "2. **关键设备状态检查**：重点关注的 `kitchen_light` 仅在特定时间点开启（05:52, 12:05, 12:35, 11:07, 12:15），且伴随厨房运动传感器（`kitchen_occupancy`）的激活，表明灯光使用与人员存在直接相关，属于正常的人控或智能联动行为。未发现灶具（`cook_surface`）长时间无人看管或烟雾报警器（`smoke_co_alarm`）触发的情况。",
    "3. **环境与传感器数据验证**：温度传感器读数在合理范围内（约24°C-25.5°C），数值随时间缓慢变化，符合室内环境温度波动特征，无突变或传感器卡死（stuck）的迹象。门窗传感器和窗帘状态未见异常开启记录。入户门锁无非法开锁记录。",
    "4. **综合判断**：所有事件均能合理解释为正常的居家生活场景，不存在入侵、火灾、跌倒或设备故障等安全风险。"
  ],
  "key_evidence": [
    "厨房灯开启时间与厨房运动传感器激活时间高度重合，证明有人在场操作。",
    "三天内的活动轨迹（客厅、厨房、卧室、玄关）呈现规律性重复，无异常中断或长时间空白。",
    "温度传感器读数稳定在舒适区间，无剧烈跳变或异常极值。",
    "未触发任何烟雾报警、漏水报警或门锁异常警报。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需采取紧急干预措施。",
    "建议定期校准温度传感器以确保长期数据准确性，尽管当前数据看起来正常。"
  ]
}
```

{
  "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。"
  ]
}


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": [
    "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逻辑。",
  "reasoning": [
    "1. 活动模式一致性分析：对比2026-07-07至07-09三天的跨天活动摘要，各房间的活动计数（如living_room约209-211次，kitchen约240-241次）保持高度一致，表明住户的生活作息规律，无突发性的大幅度行为改变或长时间静止（排除跌倒或异常不活动风险）。",
    "2. 厨房安全状态检查：虽然重点设备包含kitchen_light，但日志中仅记录了灯具的开启状态（OnOff=True），并未出现cook_surface（灶具）被激活的记录，也未触发smoke_co_alarm（烟雾报警器）。结合kitchen_occupancy传感器在中午时段频繁触发，符合老人准备午餐的正常生活场景，不存在无人看管烹饪或火灾风险。",
    "3. 环境与健康指标正常：客厅和卧室的温度读数在合理范围内波动（例如客厅从25.48°C逐渐降至24.81°C后回升，卧室维持在24°C左右），未见极端温度导致的安全隐患。所有运动传感器（Occupancy Sensor）均按预期触发和复位，未发现传感器卡死（stuck）或故障迹象。"
  ],
  "key_evidence": [
    "连续三天各房间活动计数高度稳定（Living Room: ~210, Kitchen: ~241），显示生活规律。",
    "Kitchen日志中仅有灯光开关记录，无Cook Surface激活或Smoke Alarm触发，排除火灾/忘关火风险。",
    "Temperature传感器数值随时间自然变化，处于舒适区间，无异常极值。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，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，尽管当前数据看起来正常。"
  ]
}
```

{
  "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": [
    "正常样本午餐时间有小幅波动；异常样本跨天明显后移。"

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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人在两天内的活动模式高度一致，烹饪行为正常（开启后不久即关闭），无未遂火灾、入侵或健康异常迹象。",
  "reasoning": [
    "1. 烹饪行为分析：在7月27日和28日，厨房灶具（kitchen_cook_surface）均在中午时段（约12:00-12:05）开启，并在30分钟内关闭（27日12:22关闭，28日12:28关闭）。这种‘开启-烹饪-关闭’的闭环行为符合正常的做饭习惯，未发现长时间无人看管导致的火灾隐患（unattended_cooking）。",
    "2. 环境与安全联动：尽管灶具开启，但厨房烟雾报警器（smoke_co_alarm）和漏水传感器（water_leak_detector）在整个日志期间均未触发报警，表明没有发生实际的火灾或泄漏事故。",
    "3. 活动规律性对比：两天的跨天活动摘要数据显示，各房间的活动计数非常稳定（如living_room分别为211和209，kitchen均为242），且关键设备事件的时间点（如温度上报、 occupancy 变化）在两天间具有极高的相似性。这种高度的重复性排除了突发性的行为异常（behavioral_anomaly）或老人失能/跌倒（possible_fall）的可能性，因为如果是异常情况，通常会导致活动模式的剧烈波动或长时间静止。",
    "4. 传感器状态检查：温度传感器读数随时间自然波动，无跳变或卡死现象；运动传感器在人员活动时正确上报Occupancy=1，离开后或在非活跃期无异常持续占用，表明传感器工作正常，无故障（sensor_malfunction）。"
  ],
  "key_evidence": [
    "7月27日 kitchen_cook_surface 于 12:00 开启，12:22 关闭，时长22分钟，属正常烹饪范围。",
    "7月28日 kitchen_cook_surface 于 12:05 开启，12:28 关闭，时长23分钟，与前一天模式几乎完全一致。",
    "两天内所有 smoke_co_alarm 和 water_leak_detector 均无报警记录。",
    "两天内 living_room 和 kitchen 的活动计数差异极小（<2%），显示生活规律稳定。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",
    "建议定期校准温度传感器以确保读数准确性，但目前看来工作正常。"
  ]
}
```

{
  "is_anomaly": true,

  "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。

## 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。

{
  "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。"

  "threat_description": "检测到独居老人在凌晨时段（02:18 - 05:38）卧室灯光异常开启且持续数小时，伴随全屋温度异常升高，高度疑似老人夜间起夜如厕后未归或发生跌倒/昏迷等意外情况。",
  "reasoning": [
    "时间逻辑分析：日志显示在 02:18 和 05:38 两次触发 bedroom_light 开启。对于独居老人而言，凌晨 2 点和 5 点起床并长时间亮灯是非常不寻常的行为模式，通常与睡眠障碍、起夜困难或突发身体不适有关。",
    "环境状态关联：在灯光开启期间（特别是 02:18 至 05:38），客厅、厨房、卧室的温度传感器读数持续上升（从约 23°C 升至 24°C+）。虽然空调可能未关闭，但如此长时间的无人活动（所有 occupancy_sensor 均为 0）却伴随高温，且没有检测到任何人员移动，暗示可能存在‘人’在房间内但无法移动的情况，或者房间密闭导致热量积聚（若有人被困）。",
    "行为模式缺失：在 02:18 开灯后的近 4 小时内，直到 05:38 再次开灯前，没有任何其他设备（如卫生间占用、厨房灶具、窗户开关）产生交互事件。这种长时间的‘静止 + 开灯’组合是独居老人健康危机（如跌倒后无法起身、中风昏迷）的典型特征。",
    "排除误报：虽然 02:10 有短暂的 bathroom_occupancy=1，随后立即变为 0，这符合正常起夜习惯；但紧接着的 02:18 卧室开灯后长达 3 小时的无活动记录，远超正常起夜停留时间，因此判定为异常而非单纯的习惯性起夜。"
  ],
  "key_evidence": [
    "2026-07-28T02:18:00 bedroom_light 开启，随后直至 05:38 无任何人员活动记录。",
    "在此期间 (02:18-05:38)，living_room_temp_sensor 读数从 2344 持续攀升至 2415，且所有房间 occupancy 均为 0。",
    "独居老人背景使得凌晨长时间亮灯且无后续活动成为高风险信号。"
  ],
  "recommended_actions": [
    "立即通过智能家居系统向老人发送语音提醒或电话呼叫，确认其安全状况。",
    "通知紧急联系人或家属，告知系统检测到的异常夜间活动模式。",
    "建议物业或社区服务中心安排人员上门查看，以防老人发生意外。",
    "检查卧室及走廊照明设置，考虑启用‘夜间起夜辅助模式’（自动感应开灯并延时关闭），减少老人因黑暗导致的跌倒风险。"
