## 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",
  "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": "目标设备 living_room_light_1 工作状态正常，日志显示其按用户习惯开启、调光并关闭，无异常行为。",
  "reasoning": [
    "1. 状态变化符合逻辑：living_room_light_1 在 20:10 开启（OnOff=True），随后在 20:18 将亮度调整至 30%（LevelControl.CurrentLevel=30），最后在 22:42 关闭（OnOff=False）。这一序列（开灯 -> 调暗 -> 关灯）是典型的晚间居家或睡前准备行为，符合 dimmable_light 设备的正常操作模式。",
    "2. 环境上下文支持：在灯光开启期间（20:10-22:42），客厅运动传感器（living_room_occupancy）持续报告有人存在（Occupancy=1），表明灯光的使用与人员活动一致，排除了无人自动误触发或故障亮灯的可能性。",
    "3. 无其他关联威胁迹象：同一时间段内，入户门传感器在 22:42 变为 True（关门），且之前有 False（开门）记录，结合室内人员活动，表现为正常的归家/离家闭环，未发现入侵、非法闯入或其他安全威胁特征。"

    "[2026-07-30T20:21:10] living_room_occupancy | OccupancySensing.Occupancy = 1 (及后续持续有人)"
  ],
  "recommended_actions": [
    "无需采取任何行动，当前设备运行正常。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [

## 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",

    "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",

    "推理步骤 2: 对比同一时间段内的厨房温度传感器 (kitchen_temp_sensor) 数据，其读数稳定在 2400-2500 区间，符合夏季室内高温环境下的正常物理规律，证明环境温度并未发生极端变化。",
    "推理步骤 3: 结合卧室温度传感器 (bedroom_temp_sensor) 持续稳定的低温读数（约 2400-2450），进一步确认客厅温度传感器的故障是孤立的设备问题，而非全屋环境异常或系统时钟错误。",
    "推理步骤 4: 该传感器不仅数值漂移，还可能在特定时刻报告了错误的状态（例如在 13:15 报告 28.4°C 时可能触发了错误的制冷/制热逻辑或报警），属于典型的传感器硬件故障或校准丢失。"
  ],
  "key_evidence": [
    "2026-07-03T13:15:00 living_room_temp_sensor 报告值 2840 (28.4°C)，而前后相邻时间点分别为 2505 和 2489，存在 >2°C 的瞬时剧烈跳变。",
    "同期 kitchen_temp_sensor 和 bedroom_temp_sensor 读数均在 23.5°C - 25.5°C 之间平稳波动，排除了环境整体过热的可能性。",
    "尽管在 13:00 开启了空调，但 living_room_temp_sensor 在 13:35 仍报告 27.2°C，显示传感器未能正确反映空调运行后的降温效果。"

  "recommended_actions": [
    "立即检查并重新校准客厅温度传感器 (living_room_temp_sensor)，或将其从自动化场景（如空调控制）中暂时移除。",
    "联系设备制造商进行固件更新或硬件维修，以解决传感器漂移问题。",
    "在修复前，建议人工定期手动测量客厅实际温度，以确保居住舒适度及空调系统的正常运行。"

## 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",

    "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",

  "threat_description": "卧室温度传感器 (bedroom_temp_sensor) 在 14:05:00 出现严重数据跳变，从 2360 瞬间变为 2550，随后又回落，且后续读数持续异常偏低，表明传感器可能故障或受到干扰。",
  "reasoning": [
    "推理步骤 1: 分析时间戳为 2026-07-21T14:05:00 的日志，发现 bedroom_temp_sensor 在同一秒内连续报告了两个截然不同的温度值：先是从 2360 (约 23.6°C) 突变至 2550 (约 25.5°C)，紧接着下一分钟又跳回 2470。这种在同一秒内的剧烈波动不符合物理热力学规律（室温不会瞬间变化近 2 度）。",
    "推理步骤 2: 观察该传感器在异常发生后的趋势。从 14:05 到 16:45，温度读数呈现非自然的阶梯式下降（2470 -> 2370 -> 2345 -> 2291 -> 2277），而同一时间段内客厅和厨房的温度仅缓慢下降或保持平稳。这表明传感器未能正确反映环境温度，存在漂移或校准失效。",
    "推理步骤 3: 结合独居老人场景评估风险。虽然当前未直接触发高温报警，但作为关键的生命体征辅助监测设备（用于判断老人是否长时间处于极端环境或跌倒后无法移动导致体温变化），其数据不可靠会导致系统误判室内舒适度，甚至掩盖真实的安全隐患（如空调故障导致的过热或过冷）。"

  ],
  "recommended_actions": [
    "立即通知住户或家属检查卧室温度传感器是否被遮挡、损坏或电池电量不足。",
    "建议暂时使用备用温度计手动测量卧室实际温度，以验证传感器读数准确性。",
    "若确认为硬件故障，应尽快更换传感器；在此期间，需人工关注老人健康状况及室内温湿度。"

## 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",

    "2. 设备联动逻辑：日志显示在17:00-18:00期间，卧室和客厅均有Occupancy（有人）信号，且随后温度持续下降，表明空调系统正在有效工作并维持舒适温度，未出现因设备故障导致的温度异常飙升或停滞。",
    "3. 排除传感器故障：各房间传感器读数变化平滑，无突变、跳变或死值（如长时间保持同一数值不变）。例如卧室传感器在15:45至16:10之间缓慢下降，符合热惯性特征，而非传感器卡死（Stuck）或漂移（Drift）。",
    "4. 其他事件检查：厨房窗户在12:47和18:46关闭（StateValue=False），配合厨房温度在中午较高（~27°C）后逐渐降低，符合开窗通风后关窗降温的正常生活行为，无漏水、烟雾或入侵迹象。"

    "厨房温度在12:00达到峰值27.67°C后，随着窗户关闭（12:47）及后续时间推移逐渐回落至22.83°C，符合物理散热规律。"

## 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",

    "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",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [

    "推理步骤 2: 在此活跃期间，厨房温度传感器 (kitchen_temp_sensor) 的读数从正常的摄氏度范围（约 25°C，即 2500+）突然变为 None (2026-08-22T11:01:00)，并在后续时间出现无规律的剧烈跳变（如 11:40:00 降至 2529，而之前为 2553），这不符合物理热力学规律。",
    "推理步骤 3: 考虑到独居老人的背景，厨房是火灾高发区。传感器数据的突然丢失和漂移可能导致无法准确监测过热情况，若配合灶具使用，可能掩盖火灾隐患，属于严重的传感器功能故障。"
  ],
  "key_evidence": [

    "2026-08-22T11:00:00 kitchen_light | OnOff.OnOff = True 与 11:05:00 kitchen_occupancy = 1 形成对比，证明该时段有实际活动但传感器失效。"
  ],
  "recommended_actions": [

## 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",
  "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。

{
  "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: 正常样本倒计时递减并停止；异常样本数值长时间固定。"

  "threat_description": "厨房温度传感器检测到极端高温（最高达 29.15°C，即 2915 mK），且伴随灶具开启事件，存在严重的火灾风险。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-07-04T12:01:30 厨房灶具 (kitchen_cook_surface) 被开启后，厨房温度开始异常飙升。",
    "推理步骤 2: 对比历史数据，此前厨房温度通常在 25.0°C - 25.6°C (2500mK-2560mK) 之间波动，属于正常室温范围。但在 12:05 至 12:55 期间，温度读数迅速攀升至 26.58°C、27.27°C、29.15°C 等数值。",
    "推理步骤 3: 虽然 29.15°C 对于普通烹饪可能偏高，但考虑到该数值在短时间内急剧上升且远超常规烹饪产生的温升幅度，结合 Matter 协议中温度通常以毫开尔文 (mK) 为单位报告的特性（2915 mK = 29.15°C），这种剧烈的非稳态升温模式强烈暗示了潜在的燃气泄漏燃烧失控、设备故障或传感器严重漂移导致的虚假高温报警，无论哪种情况都构成了极高的火灾安全隐患。"
