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
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",

  ],
  "recommended_actions": [
    "建议措施1",

  ]
}
```

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": [
    "时间异常：事件发生在凌晨02:07至02:30之间，属于典型的深夜时段，此时住户通常处于睡眠状态，非正常活动时间。",
    "物理入侵迹象：日志显示阳台门传感器（balcony_door_contact）在02:07变为False（即门被打开），打破了深夜门窗紧闭的安全常态。",
    "人员活动轨迹吻合：阳台门打开后1分钟（02:08）阳台灯亮起，紧接着02:09客厅运动传感器（living_room_occupancy）检测到有人（Occupancy=1）。这种从阳台进入室内并点亮灯光、触发客厅传感器的行为模式，高度疑似入侵者进入住宅内部。"

  ],
  "recommended_actions": [
    "立即触发家庭安防警报并通知住户及安保人员。",

  "threat_description": "客厅温度传感器读数异常偏高（2300-2400），远超正常室温范围，且与人体活动无合理关联，疑似传感器故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 2026-07-25T01:40:00 开始，living_room_temp_sensor 的 MeasuredValue 持续在 2300 至 2442 之间波动。考虑到 Matter 协议中温度通常以 0.01°C 为单位，该数值实际代表 23.00°C 至 24.42°C，这在夏季夜间属于正常室温范围，但需结合上下文判断。然而，仔细观察 2026-07-25T02:25:00 及之后的数据，数值稳定在 23xx 和 24xx 区间，若单位是毫摄氏度 (mK) 则高达 23 度以上绝对不可能，若单位是 0.01 度则数值本身看似正常。",
    "推理步骤 2: 重新审视数据模式：在 2026-07-25T03:14:00 检测到 occupancy=1（有人进入）后，温度并未像正常人体热源那样显著上升并维持高位，反而在随后几小时内（03:15 - 04:40）呈现不规则的剧烈波动（2377 -> 2368 -> 2382 -> 2371...），且峰值达到 2442。更关键的是，对比同时间段的其他房间（如 master_bedroom, kitchen），其温度传感器读数也在 23xx-24xx 范围内同步出现类似的高位波动，这表明可能不是单一设备故障，而是系统性的基准偏移或校准错误。",
    "推理步骤 3: 最关键的异常点在于数据的量级逻辑。如果 MeasuredValue 直接代表摄氏度，2300°C 显然不可能；如果代表 0.01°C，则 2300 = 23.00°C。但在智能家居安全分析中，如此长时间、多房间、非加热模式下温度维持在 23-24°C 且伴随高频微小抖动，同时 occupancy 频繁切换为 0 时温度不下降反升（例如 02:30 无人时 2341，03:14 有人后 2377，但 03:30 又变回 2371 而无人），这种‘热惯性’缺失和数值的不稳定性强烈暗示传感器存在漂移（Drift）或校准偏差，导致读数无法真实反映环境温度变化，从而掩盖了真实的温度趋势或产生误报风险。此外，2026-07-27T03:15:00 厨房灯开启前，厨房温度已处于高位，进一步佐证了环境感知系统的不可靠性。",
    "推理步骤 4: 综合来看，虽然 23-24°C 本身在物理上可能成立，但多房间传感器在同一时间窗口内表现出高度相关但缺乏物理因果联系的温度波动（即人走温度不降，人进温度不升），符合 Sensor Drift（传感器漂移/校准失效）的特征，可能导致火灾预警延迟或空调控制失效。"

    "多个房间（living_room, kids_room, master_bedroom, kitchen）的温度传感器在同一时间段内同步出现数值高位震荡，且波动幅度与人体热源影响不符，显示出系统性偏差。",
    "2026-07-27T03:14:00 检测到 occupancy=1 后，仅 1 分钟后的厨房灯光开启，但此前厨房温度已在高位，表明温度监测未能准确反映环境状态变化。"

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
{
  "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。

    "推理步骤 3: 晚间 21:49 记录了一次完整的出门流程（灯灭、门关、锁闭），随后直到日志结束（23:46）客厅仍检测到有人（可能是宠物或延迟清除的传感器数据，但结合前文出门动作，更可能是住户未完全离开或传感器误报，但鉴于门锁已闭且无异常闯入事件，整体风险可控）。综合来看，所有设备交互逻辑自洽，属于正常家庭活动。"
  ],
  "key_evidence": [

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
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",

}
```

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 2: 分析清晨时段 (06:53 - 08:29)，门锁先被手动上锁 (LockOperationType=1)，随后门磁闭合 (True)，接着又手动解锁 (LockOperationType=0) 并开门。这一序列符合住户早晨出门前检查/上锁，发现需要再次进出或调整，最终离家的标准操作流程。",
    "推理步骤 3: 分析傍晚时段 (20:37)，门磁先变为 True (关门)，随后门锁被手动上锁 (LockOperationType=1)。这是典型的住户下班回家进门并锁门的动作。随后的日志显示客厅有人，直到深夜 23:55 仍有活动记录，符合独居老人的日常作息规律。",
    "推理步骤 4: 综合所有事件，时间线连贯，设备状态变化逻辑自洽（开锁->开门->进屋/出屋->关门->锁门），且与独居老人的生活习惯相符，不存在强行闯入、尾随或设备故障的迹象。"

    "推理步骤 3: 结合住户习惯，凌晨 03:14 检测到 occupancy=1（有人进入），随后温度读数继续异常升高。如果这是真实的高温环境，通常会触发空调制冷或导致人员不适离开，但日志显示人员短暂停留后离开，且第二天同一时间点的温度依然遵循类似的异常上升趋势。这种跨天重复的、不符合热力学规律的数值增长，强烈指向 sensor_drift（传感器漂移/故障），而非真实的环境温度变化。"

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。
