## 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",

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。

    "推理步骤 1: 时间窗口分析。日志显示在 02:10 至 05:41 之间，所有房间（living_room, bedroom, kitchen, bathroom, entrance）的运动传感器均报告 Occupancy = 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。在完全无人员活动的情况下（02:18），卧室灯突然被打开（OnOff.OnOff = True）。如果是正常起床如厕，通常会有进入卧室的占用信号先于开灯，或者随后有离开卧室的占用信号；但在长达数小时的无人状态下单独开灯，不符合常规生理习惯，暗示可能有人被困在房间内无法移动，或设备误报但结合后续长时间无活动更倾向于前者。",
    "推理步骤 3: 环境状态佐证。在此期间，厨房温度持续上升（从 23°C 升至 26°C+），而客厅和卧室温度变化相对平缓。这种温差可能意味着空调系统因无人操作而处于非节能模式，或者室内热源（如老人身体）导致局部升温，但最关键的证据是直到 05:41 卫生间才再次检测到有人活动，中间间隔过长，增加了健康风险等级。",
    "推理步骤 4: 综合评估。考虑到住户为独居老人，夜间长时间无生命体征活动（通过运动传感器推断）伴随异常的灯光触发，高度疑似老人夜间跌倒后无法起身，或突发疾病昏迷，属于紧急健康关注事件。"

## 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: ...",

    "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。",
  "reasoning": [
    "1. 活动规律性分析：对比2026-07-12至07-14的跨天摘要数据，各房间的活动计数（如living_room约210次，bedroom约240次）保持高度一致，表明住户的生活作息非常规律，无突发的长时间静止（可能暗示跌倒或昏迷）或异常的高频活动。",
    "2. 关键时间窗行为正常：在早晨07:30-09:30的关键起床和准备时段，厨房(kitchen)和客厅(living_room)的运动传感器均检测到活跃状态（Occupancy=1），且温度传感器读数随人体活动和空调运行呈现合理波动（如客厅从25.23°C升至25.47°C），符合老人早起活动的特征。",
    "3. 门锁与安防状态正常：入户门传感器仅在早晨短暂开启后关闭（如08:23 False），且没有反复尝试开锁或深夜非法入侵的迹象。08:34的门锁状态更新（LockState=2，通常表示锁定）发生在出门后，逻辑连贯。",
    "4. 无危险设备告警：日志中未出现烟雾报警器触发、漏水传感器报警或灶具长时间无人看管（结合运动传感器持续有人）的情况。"
  ],
  "key_evidence": [
    "连续三天早晨07:30-09:30期间，kitchen_occupancy和living_room_occupancy均有持续的Occupancy=1记录，证明住户正常起床活动。",
    "跨天活动摘要数据显示各房间活动频次标准差极小（例如卧室分别为243, 242, 241），排除了突发健康事件导致的异常静止。",
    "front_door_contact在08:23变为False（关门），随后无其他非授权开启记录，门锁状态正常。"
  ],
  "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，尽管当前数据看起来正常。"
  ]
}
```

{
  "is_anomaly": true,

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: ..."
  ],

    "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且环境参数正常。",
  "reasoning": [
    "1. 活动模式分析：日志显示住户在早晨（07:25-09:30）有规律地出现在厨房、客厅和卧室，符合独居老人的日常作息（起床、洗漱、早餐）。各房间运动传感器状态变化连贯，无长时间静止导致的异常离线或误报。",
    "2. 安全设备状态：三天内所有烟雾报警器（smoke_co_alarm）和漏水传感器（water_leak_detector）均未触发报警事件，表明无火灾、燃气泄漏或水患风险。",
    "3. 门锁与入侵检测：入户门传感器仅在特定时间点记录状态（如08:24关闭），且伴随玄关/入口运动传感器激活，随后进入室内活动，符合正常离家或归家行为。未发现非授权时段的门锁开启或非法入侵迹象。",
    "4. 环境数据稳定性：温度传感器读数在合理范围内波动（约24-25°C），无剧烈跳变或传感器故障迹象。"
  ],
  "key_evidence": [
    "连续三天早晨07:30-09:30期间，kitchen_occupancy、living_room_occupancy、bedroom_occupancy依次或同时激活，呈现典型的晨间活动轨迹。",
    "所有安全类传感器（烟雾、漏水）在整个日志窗口期内无任何报警触发记录。",
    "front_door_contact 状态变化与 entrance_occupancy 及后续室内活动逻辑一致，无异常开锁记录。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期维护传感器电池，确保长期稳定运行。"
  ]
}
```

{
  "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": [
    "正常样本仍保持多房间活动；异常样本逐渐收缩到卧室附近。"
  ],
  "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
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": [

    "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且传感器数据正常。",
  "reasoning": [
    "1. 活动模式分析：日志显示住户在每天上午10:30至下午14:00左右活跃于客厅、卧室和厨房，符合独居老人白天的常规作息（如起床、用餐、休息）。入户门传感器仅在白天短暂触发（如11:49, 12:14等），且伴随玄关/客厅运动传感器激活，推测为正常进出或取快递等行为，无夜间非法入侵迹象。",
    "2. 厨房安全分析：虽然重点设备 kitchen_light 多次开启，但厨房灶具 (cook_surface) 状态始终未报告异常（日志中未出现持续的烹饪负载或烟雾报警），且厨房温度传感器读数稳定在25°C左右（Matter协议中通常以0.1度为单位，2527代表25.27°C），无过热现象。未发现无人看管烹饪导致的火灾风险。",
    "3. 传感器健康检查：所有温度传感器读数随时间推移呈现合理的自然波动（如从25.4°C缓慢降至24.9°C），符合室内环境温度变化规律，无传感器卡死（stuck）或漂移（drift）迹象。运动传感器频繁上报 'Occupancy=1' 是存在人员活动的正常表现，而非故障。"
  ],

    "入户门锁及传感器仅在白天特定时段短暂激活，与室内其他区域活动同步，符合正常生活轨迹。",
    "温度数据呈线性缓变趋势，排除传感器硬件故障。"

  "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。

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
{

  "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
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": [

    "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：日志显示住户在早晨7:30-9:00之间活跃（厨房、客厅、卧室均有 occupancy 记录），随后活动减少，符合独居老人的日常作息（早起、活动、休息）。夜间23:49-23:50仍有客厅活动记录，可能是起夜或睡前最后活动，属于正常范围。",
    "2. 门锁状态分析：入户门锁（front_door_lock）在08:22和08:31显示 LockState = 2（通常表示 Locked 或 Unlocked 取决于具体实现，但结合 entrance_occupancy 持续为 1 且无异常开启/关闭序列，更倾向于门已锁好或处于常闭状态下的正常监测）。没有发现非正常时间的开门记录或多次失败尝试。",
    "3. 传感器数据一致性：温度传感器读数（如 living_room_temp_sensor 在 25.18°C - 25.56°C 之间波动）变化平缓，符合室内环境温度随时间缓慢变化的物理规律，无突变或漂移迹象。运动传感器（occupancy_sensor）的触发与住户活动逻辑一致，未发现长时间静止后的突然激活（可能暗示跌倒）或长时间无活动后的异常唤醒。",
    "4. 跨天对比：7月9日、10日、11日的活动摘要数据显示各房间的活动计数非常稳定（living_room ~209-211, kitchen ~237-239），表明住户生活习惯高度一致，无突发性行为改变（如整日不出门或深夜频繁外出），排除了健康突发状况或外部入侵的可能性。"
  ],
  "key_evidence": [
    "跨天活动摘要显示各房间活动计数连续三天保持稳定，无剧烈波动。",
    "温度传感器读数在合理范围内平滑变化，无异常跳变。",
    "运动传感器触发时间与住户日常作息（早晨起床、活动）相符，无长时间异常静止或夜间高频异常活动。",
    "门锁状态记录简单，未见异常开锁或非法入侵迹象。"
  ],
  "recommended_actions": [
    "继续常规监控，无需立即干预。",
    "建议定期校准温度传感器以确保长期数据准确性。"
  ]

## 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：日志显示住户在每天上午10:30至下午14:00左右活跃于客厅、卧室和厨房，符合独居老人白天的常规作息（如起床、准备午餐、休息）。入户门传感器仅在白天短暂触发（如11:26, 12:01等），且伴随室内运动传感器激活，推测为正常进出或检查门窗，无夜间非法入侵迹象。",
    "2. 烹饪安全检查：虽然重点设备 kitchen_light 多次开启（如06:04, 12:05, 12:35, 12:15），但厨房灶具[cook_surface]在整个日志期间从未被激活（无状态变化记录）。这表明灯光开启可能仅用于照明而非烹饪，或者烹饪行为未被该特定片段捕获，但结合没有烟雾报警器报警和温度异常，暂不判定为未看管烹饪风险。",
    "3. 环境与设备状态：各房间温度读数（约24-25°C）处于舒适范围，无剧烈波动。所有传感器（运动、温度、接触）均返回有效数据，未发现传感器卡死（stuck）或漂移（drift）的异常恒定值。窗帘在中午时段打开（位置10000/100%），符合自然光照习惯。"
  ],
  "key_evidence": [
    "全天无 cook_surface 激活记录，排除火灾/未看管烹饪的直接证据。",
    "入户门仅在白天短暂开启，且与室内人员活动同步，无异常闯入模式。",
    "温度传感器数值稳定在2400-2550之间（对应24-25.5°C），无极端值。",
    "运动传感器在白天持续有规律地报告占用状态，表明住户生命体征正常。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需紧急干预。",
    "建议确认厨房灯频繁开启是否仅为照明需求，若涉及烹饪，可进一步关联灶具传感器数据以完善安全闭环。"
  ]
}
```
