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",

}
```

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. 温度数据解读：日志中的 `TemperatureMeasurement.MeasuredValue` 数值（如 2249, 2256）符合 Matter 协议标准，单位为 0.01°C，即实际温度约为 22.49°C - 22.63°C。所有房间温度均处于舒适范围内，且变化平缓，无剧烈波动，排除火灾或传感器故障导致的极端读数。",
    "2. 人员活动模式分析：在 22:15 至 23:25 期间，玄关 (entrance)、客厅 (living_room) 和餐厅 (dining_room) 的运动传感器多次触发（Occupancy=1），这通常表明住户在家中走动、进行晚间活动（如看电视、聊天或准备休息）。这种多区域的活动是典型的居家行为，而非入侵者的快速移动或单一角落的静止停留。",
    "3. 门锁与安防状态：22:48 左右，入户门传感器显示开启 (True)，随后门锁执行了手动上锁操作 (LockState=1, OperationSource=Manual)。结合此时玄关和客厅有人员活动，这极有可能是住户回家后的正常关门落锁行为，或者是检查门窗安全，并非非法入侵迹象。",
    "4. 设备控制逻辑：22:48 左右，客厅主灯关闭、空调关闭、主卧窗帘完全闭合 (100%)、主卧床头灯关闭。这一系列动作具有高度的一致性，符合住户准备就寝或进入休息模式的典型习惯（关灯、关空调、拉窗帘）。",
    "5. 卫生间活动：主卫运动传感器在 22:29 和 22:59 显示无人 (0)，中间时段有人，符合正常的如厕或洗漱时长，未发现长时间滞留等异常情况。"

  "key_evidence": [
    "Matter 协议温度值 2249-2263 对应室温约 22.5°C，属正常范围。",
    "22:48 时刻出现联动行为：客厅灯/空调关闭 + 主卧窗帘闭合 + 入户门上锁，符合睡前/归家后的常规生活逻辑。",
    "多房间（玄关、客厅、餐厅）频繁的运动检测证实了住户在家中的正常活动轨迹。"

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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",

    "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

  "threat_description": "未检测到安全威胁或设备异常，所有日志记录符合正常家庭晚间活动模式。",
  "reasoning": [
    "1. 温度数据合理性分析：日志中的温度传感器数值（如2334, 2309, 2287等）明显高于常规摄氏度读数（通常15-30°C）。在Matter协议中，TemperatureMeasurement.MeasuredValue的单位是厘氏度（centi-degrees Celsius），即实际温度需除以100。例如2334代表23.34°C，2267代表22.67°C。这些数值处于舒适的室内温度范围（约22-23°C），且随时间推移呈现夜间自然降温趋势，无突变或漂移，表明传感器工作正常。",
    "2. 人员活动模式分析： occupancy_sensor（运动传感器）在客厅、餐厅、主卧、儿童房和玄关之间频繁切换状态（Occupancy=1/0），时间间隔从几分钟到十几分钟不等。这符合家庭成员在晚间进行休闲、用餐、休息等正常活动的行为特征。没有发现长时间静止不动导致的误报，也没有出现非居住区域（如阳台、次卧）的异常入侵迹象。",
    "3. 关键设备状态检查：厨房灶具（cook_surface）在19:00关闭，之后无开启记录，排除了无人看管烹饪的风险。入户门锁（door_lock）和窗户传感器（contact_sensor）在日志片段中未报告任何打开或异常状态变化（仅记录了运动传感器和温度传感器），结合运动传感器的活动轨迹，未发现非法入侵迹象。"
  ],
  "key_evidence": [
    "温度值解析为22-23°C左右，符合舒适室温，且变化平滑，无传感器故障特征。",
    "运动传感器在多个房间交替激活，符合多人口家庭晚间正常生活轨迹。",
    "厨房灶具已关闭，无持续加热风险；门窗传感器无异常触发记录。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议定期校准温度传感器以确保长期读数准确性（尽管当前读数看起来合理）。"

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。

    "2. 数据一致性检查：在两个时间点（23:00 和 23:30），所有列出的运动传感器（living_room, dining_room, master_bedroom, second_bedroom, kids_room, master_bathroom, entrance）均报告 Occupancy = 0（无人）。这种全区域一致的“静默”状态表明没有异常的人员移动或入侵迹象。",
    "3. 排除误报可能：虽然主卧、次卧等私人区域也显示无人，但这可能是因为住户尚未入睡、已离开房间或传感器灵敏度设置问题。然而，结合深夜时间和公共区域的完全静止，这更倾向于是一种正常的夜间静态场景，而非需要立即干预的安全事件。除非有特定的健康监控需求（如长时间无活动），否则仅凭此日志不足以判定为异常。"

## 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。

  "threat_type": "none",
  "threat_description": "所有区域运动传感器均显示无人状态，符合深夜时段的正常家庭行为模式，未检测到安全威胁。",
  "reasoning": [
    "1. 时间分析：日志记录的时间为 2026-07-26 的 23:00 和 23:30，属于深夜时段，通常家庭成员处于休息或睡眠状态。",
    "2. 状态一致性检查：在两个时间点（23:00 和 23:30），客厅、主卧、次卧、卫生间及玄关的所有运动传感器（occupancy_sensor）均报告 Occupancy = 0（无人）。这种全屋无人的状态在深夜是高度一致的。",
    "3. 排除异常逻辑：虽然深夜全屋无人可能让人联想到“离家”，但考虑到这是两室一厅的家庭布局，且没有伴随门锁异常开启、窗户异常打开或其他入侵迹象，最合理的解释是住户正在卧室休息，或者运动传感器存在短暂的检测盲区/延迟，但这属于正常生理活动范围，不构成安全威胁。若为入侵，通常会伴随特定区域（如入户门附近）的传感器触发，而非全静默。"

## 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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的晚间居家活动及夜间就寝准备行为。",
  "reasoning": [
    "1. **人员活动模式正常**：21:55至22:48期间，客厅、玄关和主卧的运动传感器频繁触发（Occupancy=1），表明住户在客厅活动并偶尔进入卧室，符合晚间休闲或准备休息的行为特征。次卧和卫生间长时间无活动（Occupancy=0），符合无人居住状态。",
    "2. **就寝行为逻辑一致**：22:48左右，住户执行了一系列连贯的就寝动作：关闭客厅主灯和空调，关闭主卧灯光，并将主卧窗帘完全关闭（CurrentPositionLiftPercent100ths = 10000，即100%闭合）。这一系列操作具有明确的时间顺序和逻辑关联，是典型的睡前准备行为。",
    "3. **入户门状态安全**：22:48:19入户门传感器显示开启（True），随即22:48:20门锁记录了一次手动上锁操作（LockOperationType=0通常指锁定/加锁），且LockState变为1（Locked）。这表明住户在关闭室内设备后，确认了入户门的安防状态，或者刚刚完成回家后的关门落锁流程（考虑到时间点和后续室内活动，更可能是回家后的整理或检查，但无论哪种情况，最终门锁处于锁定状态，无入侵迹象）。",
    "4. **环境数据稳定**：温度传感器读数在22.4°C - 22.7°C之间波动，属于正常的室内环境温度范围，无火灾或极端天气导致的异常升温。"
  ],
  "key_evidence": [
    "22:48:00-22:48:24: 客厅灯关、客厅空调关、主卧灯关、主卧窗帘关闭、入户门上锁。这是一组高度相关的就寝/离家安全检查序列。",
    "22:48:20: front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Manual) 且 LockState = 1，确认门锁已物理锁定。",
    "21:56-22:58: 客厅和玄关运动传感器周期性激活，证明有人在家，排除了空房被盗风险。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有自动化规则，确保夜间窗帘自动闭合和门锁状态监控正常运作。"
  ]
}
```

{
  "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。

## 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: ...",

    "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_type": "none",
  "threat_description": "未检测到安全威胁，所有设备状态符合夜间正常居住模式。",
  "reasoning": [
    "1.  occupancy传感器分析：从22:00至23:30，客厅、餐厅、主卧、次卧、儿童房、主卫及玄关的运动传感器均持续报告 Occupancy = 0（无人）。这符合家庭成员在深夜时段处于休息或静止状态（如睡眠）的正常行为模式，并非异常静默或入侵迹象。",
    "2. 温度数据分析：各房间温度传感器读数在22.4°C至22.8°C之间波动（Matter协议中通常以0.01摄氏度为单位，即2257代表22.57°C）。数值变化平缓且处于舒适区间，无剧烈跳变，表明空调系统运行稳定或环境温度自然调节，不存在火灾导致的温度骤升或传感器故障。",
    "3. 关键安防设备状态：日志中未出现入户门锁的异常开启记录、窗户传感器的触发报警、烟雾/一氧化碳报警器的激活或漏水传感器的警报。结合无人活动的背景，家庭环境处于安全的非活跃状态。"

  "reasoning": [
    "推理步骤 1: 分析温度数据格式，发现所有房间的温度传感器报告值均在 2241 至 2278 之间。在 Matter 协议及常见智能家居系统中，TemperatureMeasurement.MeasuredValue 通常以 0.1 摄氏度为单位存储整数。若按此标准解读，实际温度为 22.41°C 至 22.78°C，这在夏季夜晚属于正常范围。然而，结合日志中频繁出现的'2257'、'2265'等数值，需进一步确认是否发生了位元移位错误或单位混淆。",
    "推理步骤 2: 观察时间序列变化，从 21:55 到 23:55，温度读数在 2240-2280 区间内剧烈波动（例如 kids_room 从 2250 跳变到 2261 再回到 2248）。真实的室内环境温度在短时间内不会发生如此大幅度的无规律震荡，这种‘锯齿状’的高频波动不符合热力学特性，强烈暗示传感器固件存在 Bug、通信丢包导致的乱码，或者设备被恶意篡改/干扰。",
    "推理步骤 3: 交叉验证 occupancy 数据，所有房间在 22:00 后均显示无人（Occupancy=0），说明住户已休息。在此场景下，如果温度传感器真实反映的是高温（如 220+ 摄氏度），将构成严重的火灾风险；但考虑到物理不可能性，最合理的解释是传感器数据漂移（Drift）或故障（Malfunction），导致中央控制系统接收到的环境参数完全失真，可能引发错误的 HVAC 控制逻辑或安全警报失效。"

  "key_evidence": [
    "所有温度传感器读数集中在 2241-2278 区间，若按 0.1 度单位解读则数值合理，但若按原始整数解读则远超物理极限。",
    "同一时间段内，不同房间的温度读数呈现非物理性的剧烈高频波动（如儿童房在 5 分钟内从 2250 升至 2261 又降至 2248）。",
    "尽管全屋无人，温度读数并未呈现正常的缓慢下降趋势，反而维持高位震荡，符合传感器故障特征。"

  "recommended_actions": [
    "立即检查所有温度传感器的固件版本，并尝试重启相关设备以排除临时性通信错误。",
