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",

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。

  "reasoning": [
    "1. 分析时间窗口：所有事件发生在2026-07-07的22:46至23:29之间，属于深夜时段。",
    "2. 分析活动模式：日志显示住户在卧室(22:46)、玄关(22:47)、厨房(22:48)、客厅(22:49)依次出现活动，随后在约20分钟后重复了类似的路径（卧室->玄关->厨房->客厅）。这种高频次的跨房间移动不符合正常的就寝习惯。",
    "3. 排除外部威胁：入户门传感器未触发开启记录，且活动主要发生在室内，无证据表明有外人入侵（intrusion）或尾随（tailgating）。",
    "4. 评估健康风险：考虑到用户为“独居老人”，深夜频繁起床走动可能暗示睡眠障碍、认知障碍（如痴呆症早期的游走行为）或身体不适。虽然这不属于紧急的安全事故（如跌倒或火灾），但属于需要关注的“行为异常”或“健康关切”。然而，仅凭运动传感器数据无法确诊跌倒或严重疾病，且没有伴随其他危险信号（如烟雾、漏水、门锁异常），因此判定为非紧急异常，归类为正常范围内的行为观察，无需立即干预，但建议后续关注。"

    "入户门锁及窗户传感器在此期间无异常开启记录。"
  ],
  "recommended_actions": [
    "1. 保持监控：继续观察后续几天的夜间活动频率，确认是否为持续性行为。",
    "2. 家属关怀：建议联系子女或照护者，询问老人当晚是否有不适、失眠或意识模糊的情况。",
    "3. 环境检查：确保夜间通道无障碍物，防止因视力不佳或意识不清导致跌倒。"

  "threat_description": "未检测到安全威胁或异常情况，日志显示为独居老人在夜间正常的居家活动及环境数据上报。",
  "reasoning": [
    "1. 活动模式分析：日志显示从22:15到23:50期间，客厅、卧室、厨房和玄关的运动传感器频繁触发（Occupancy=1），且卫生间传感器间歇性触发后归零（Occupancy=0）。这种多房间、高频次的活动轨迹符合独居老人在睡前进行洗漱、整理或短暂休息的正常行为模式，未发现长时间静止不动导致的‘异常无活动’警报。",
    "2. 温度数据分析：各房间温度传感器上报的数值（如客厅2249-2275，卧室2147-2175，厨房2241-2273）在Matter协议中通常表示摄氏度乘以100的值（即22.49°C - 22.75°C等）。这些数值处于人体舒适区间，且变化平缓，没有突发的极端高温（火灾风险）或低温（设备故障/管道冻结风险）。",
    "3. 关键安全设备状态：日志中未出现烟雾报警器（smoke_co_alarm）、漏水传感器（water_leak_detector）或门窗传感器（contact_sensor）的报警状态。入户门锁也未记录到非法开启或异常操作。所有涉及安全的Cluster Attribute均保持正常静默状态。"

{

  "threat_description": "温度传感器读数严重偏离物理现实，显示为异常高温（约 22.5°C * 10 = 225°C），存在严重的传感器漂移或故障风险。",
  "reasoning": [
    "推理步骤 1: 分析日志中的温度数据，发现所有房间的温度传感器（living_room_temp_sensor, bedroom_temp_sensor, kitchen_temp_sensor）报告的 MeasuredValue 均在 2147 到 2275 之间。",
    "推理步骤 2: 根据 Matter 协议标准及常见 IoT 设备规范，TemperatureMeasurement.MeasuredValue 通常以 0.01°C 为单位。将日志数值除以 100，实际温度约为 21.47°C 至 22.75°C。虽然这个范围在物理上是合理的室温，但需要结合上下文确认单位。然而，仔细观察数值分布（如 2249, 2256, 2261），它们非常接近整数倍，且变化幅度极小（个位数波动）。如果单位是 0.1°C，则温度为 21.47°C - 22.75°C，这是完全正常的夏季室内温度。",
    "推理步骤 3: **重新评估**：让我再次仔细检查数值逻辑。如果单位是 0.01°C，2249 代表 22.49°C。卧室 2151 代表 21.51°C。厨房和客厅略高，符合常理。数值随时间有微小波动（例如从 2249 变到 2256），这符合环境温度自然变化的特征。 occupancy 传感器在 22:17-22:20 期间依次触发（客厅->卧室->厨房->玄关），随后在 22:37 再次出现类似序列，表明老人正在家中正常活动（如做饭、走动）。卫生间 occupancy 在 22:23 和 22:53 变为 0，符合使用习惯。",
    "推理步骤 4: **最终修正判断**：之前的“异常高温”假设是错误的。数值 2249 对应 22.49°C 是完全正常的室温。没有检测到入侵、火灾、漏水或设备卡死等迹象。老人的活动轨迹连贯，传感器状态与独居老人的夜间/晚间活动模式一致。因此，该日志片段反映的是正常的家庭环境状态。"
  ],
  "key_evidence": [
    "温度数值换算后（除以 100）处于 21.5°C - 22.8°C 的正常室温范围内，无超温报警。",
    " occupancy 传感器序列（客厅->卧室->厨房->玄关）呈现规律性的移动模式，符合单人居住的生活轨迹。",
    " 卫生间 occupancy 传感器间歇性归零，符合洗漱或如厕后的离开行为。"
  ],
  "recommended_actions": [
    "无需紧急干预，系统运行正常。",

## 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。

    "4. 确认正常性：second_bedroom（次卧）和 master_bathroom（主卫）显示 Occupancy=0，表明这些区域无人，符合夜间休息时的分布逻辑。整体数据流连贯，无设备故障（如传感器卡死导致持续高频误报）的迹象，因为每次触发后都有合理的间隔，且不同房间交替出现，非单一设备异常。"

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

## 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。

Chosen response:
{
  "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: 日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "key_evidence": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
{
  "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": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "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。

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",

  "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。

System:
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。
