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。

  "threat_description": "检测到的是独居老人在夜间进行常规活动（如散步、去卫生间或查看房间）的正常行为模式，未构成安全风险。",
  "reasoning": [
    "1. 分析时间背景：事件发生在深夜 22:46 至 23:28 之间，属于典型的夜间休息时段。对于独居老人，夜间起夜、喝水或短暂走动是常见且正常的生理需求。",
    "2. 分析空间分布与逻辑：运动传感器在厨房、玄关、卧室和客厅依次触发，且 Bathroom（卫生间）传感器在短时间内（约1-2分钟间隔）出现 'Occupancy=0' 的状态变化。这符合‘从卧室/客厅出发 -> 进入卫生间 -> 离开卫生间’的行为闭环。虽然日志中 bathroom_occupancy 显示为 0，但在 occupancy_sensor 的语境下，结合前后其他房间有人活动的记录，这通常表示人员离开了卫生间区域，或者传感器检测到了短暂的无人状态后再次被其他区域的活动覆盖，并未出现长时间静止不动（跌倒风险）或异常入侵特征。",
    "3. 排除安全威胁：所有触发设备均为室内运动传感器，没有涉及入户门锁（door_lock）的非法开启、窗户传感器（contact_sensor）的异常打开或烟雾/漏水报警。活动轨迹分散但有序，符合老人在家中不同房间间移动的习惯，不存在外部入侵（intrusion）或内部危险（fire/water leak）的迹象。"

    "Bathroom 传感器状态变化与其他房间活动存在时间关联，符合如厕或洗漱后的离开行为。",

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
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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",

    "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",

  "reasoning": [
    "推理步骤 1: 分析日志发现，在 2026-08-04T19:08:00 时，厨房温度传感器 (kitchen_temp_sensor) 报告的温度值为 'None'，而此前后几分钟（如 19:00 和 19:15）均正常上报数值（约 2300 Kelvin/23°C）。",
    "推理步骤 2: 结合上下文，此时段为晚间活跃期，其他房间（客厅、餐厅、儿童房等）的 occupancy 传感器频繁报 1，且温度传感器持续正常工作，排除了全屋网络中断的可能性。",
    "推理步骤 3: 该现象符合 Matter 协议中设备临时离线、重启或传感器内部读取失败的特征，属于典型的传感器故障（Sensor Malfunction），而非环境异常或入侵行为。"
  ],
  "key_evidence": [
    "[2026-08-04T19:08:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None",

  ],
  "recommended_actions": [
    "检查厨房温度传感器的电源连接及电池状态（如有）。",

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

  ],
  "recommended_actions": [

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。

    "2. 设备状态检查：卧室灯在22:42关闭后，仅在22:44有亮度调整记录，随后运动传感器归零，表明用户可能离开卧室或入睡，逻辑连贯。卫生间和厨房的传感器在夜间保持空闲或短暂使用，未见异常开启。",
    "3. 环境数据合理性：温度传感器读数（如客厅~22.6°C，卧室~21.6°C）处于舒适区间，且数值随时间呈现缓慢的自然波动，未发现突变的‘sensor_drift’或‘sensor_malfunction’。未检测到烟雾、漏水、门窗非法开启或灶具未关等高危事件。"
  ],
  "key_evidence": [
    "卧室与客厅运动传感器在22:15-23:55期间多次出现 Occupancy=1 到 0 的循环，符合正常人类活动规律。",

## 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

## 任务
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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

  "reasoning": [
    "1. 人员活动模式分析：从17:55至22:35，卧室、客厅、厨房和玄关的运动传感器持续报告占用状态（Occupancy=1），表明住户整晚在屋内活动，符合独居老人晚间休息前的正常生活轨迹（如看电视、准备睡觉等）。",
    "2. 关键安全事件排查：日志中未出现烟雾报警器（smoke_co_alarm）触发、漏水传感器（water_leak_detector）报警或灶具异常开启的情况，排除了火灾、燃气泄漏和水患风险。",
    "3. 门锁与入侵检测：入户门锁仅在20:43:16记录了一次锁定操作（LockState=1），且此前有玄关运动传感器活跃，这符合住户睡前反锁大门的正常行为，未发现非法入侵或尾随迹象。",
    "4. 设备健康检查：所有温度传感器读数在合理范围内（约21-23°C），且变化平缓；运动传感器状态切换逻辑连贯，未见长时间卡死或数据跳变异常，排除传感器故障。"
  ],
  "key_evidence": [
    "17:55 - 22:35 期间，bedroom_occupancy, living_room_occupancy, kitchen_occupancy 多次交替为 1，证明住户持续在场。",
    "20:43:16 front_door_lock | DoorLock.LockState = 1，结合前后玄关活动，判定为正常的睡前锁门行为。",
    "全程无 smoke_co_alarm 或 water_leak_detector 的报警事件。",
    "TemperatureMeasurement.MeasuredValue 数值稳定，无剧烈波动或超出物理常识的值。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控夜间（23:00后）是否有长时间无活动情况，以预防可能的突发健康状况。"
  ]
}
```

    "3. 卫生间活动分析：卫生间运动传感器在 22:49:54、23:19:54、23:49:54 间歇性变为 0 (无人)，这通常意味着住户短暂进入卫生间使用后又离开，或者传感器因距离较远/角度问题检测不到躺卧姿态。结合卧室持续有人，这种间歇性的卫生间“无人”信号与正常的如厕习惯相符，并非设备故障或长时间未使用的异常。",

## 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",

    "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

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全风险，日志显示为正常的夜间室内活动模式。",
  "reasoning": [
    "1. 分析时间背景：所有事件发生在2026-08-06的22:47至23:30之间，属于典型的夜间休息时段。",
    "2. 分析人员轨迹：日志显示入户门（entrance）、客厅（living_room）和主卧（master_bedroom）的运动传感器频繁触发（Occupancy=1），且呈现周期性或持续性状态。这符合住户在夜间于公共区域（玄关、客厅）走动，并可能进入卧室休息或起夜的行为特征。",
    "3. 排除异常迹象：未检测到任何门窗传感器被非法打开、门锁异常操作、烟雾/漏水报警或厨房设备异常开启等危险信号。次卧和卫生间的无活动（Occupancy=0）也符合夜间大部分家庭成员已休息的预期。整体行为逻辑连贯，无入侵或设备故障迹象。"
  ],
  "key_evidence": [
    "22:47-23:28期间，entrance, living_room, master_bedroom 运动传感器持续报告 Occupancy=1，表明有人在这些区域活动。",
    "second_bedroom 和 bathroom 传感器报告 Occupancy=0，符合夜间非活跃区域的正常状态。",
    "无任何安全类传感器（如door_lock, smoke_co_alarm, water_leak_detector）触发告警或异常状态变化。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控夜间活动模式，若发现长时间无人但传感器仍触发，或深夜有陌生区域活动，再进一步排查。"
  ]

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。

    "2. 卫生间使用模式正常：卫生间运动传感器在22:10、22:40、23:10分别出现Occupancy=0（离开）的状态，间隔约30分钟。这表明住户多次进入并离开卫生间，每次停留时间合理，没有长时间滞留（可能跌倒）或长时间无响应（可能昏迷）的迹象。",
    "3. 环境数据稳定：各房间温度传感器读数在正常范围内波动（卧室~21.4-21.6°C，客厅/厨房~22.4-22.7°C），数值变化平缓，无剧烈跳变，表明传感器工作正常且室内环境舒适，无火灾或极端天气导致的异常升温。",
    "4. 无入侵迹象：入户门传感器仅在玄关运动传感器触发时伴随活动，但日志中未记录门锁状态变更（如开锁失败、非法开启）或窗户传感器的异常触发。所有活动均发生在室内已知区域，符合住户在家行为。"
