## 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",
  "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: ..."
  ],

    "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": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "threat_description": "电器运行时间异常长",
  "reasoning": [
    "推理步骤1: 设备持续运行超过常规时长",
    "推理步骤2: 倒计时未按预期减少",
    "推理步骤3: 存在过热或故障风险"
  ],
  "key_evidence": [
    "设备持续运行超过常规时长",
    "倒计时未按预期减少",
    "存在过热或故障风险"
  ],
  "recommended_actions": [
    "标记为设备异常长运行，建议停机检查。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "设备运行状态正常，温度下降符合洗碗机工作逻辑，无安全威胁。",
  "reasoning": [
    "推理步骤 1: 分析厨房温度传感器数据，发现从 12:50 到 17:25，温度值（单位应为 0.01°C）呈现持续且稳定的下降趋势（从 250.2°C 降至 234.8°C），这符合洗碗机在清洗和烘干过程中消耗热量或环境自然降温的物理规律，不存在异常升温导致的火灾风险。",
    "推理步骤 2: 检查洗碗机状态日志，OperationalState 显示为运行中（1），CountdownTime 从 5400 秒逐渐减少至 5200 秒，表明设备正在按计划执行任务，未出现卡死、意外停止或超时等故障迹象。",
    "推理步骤 3: 结合 occupancy_sensor 数据，虽然客厅、卧室、卫生间无人，但厨房作为作业区域有设备运行，且温度变化与设备运行时间高度相关，属于典型的居家生活场景，未发现入侵、尾随或传感器故障等异常模式。"
  ],
  "key_evidence": [
    "kitchen_temp_sensor 数据显示温度随时间单调递减，无突变或异常升高。",
    "kitchen_dishwasher CountdownTime 数值稳定递减，证明设备正常运行。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，继续监控即可。",
    "可等待洗碗机完成当前周期后自动复位。"
  ]
}
```

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。

    "推理步骤 1: 分析时间线发现，在 2026-07-09T18:00:00 之后，厨房温度传感器读数出现异常飙升。从正常的 ~23°C (2350 mK) 迅速上升至 18:02 的 28.4°C (2840 mK)，并在随后几分钟内持续攀升至 18:25 的 27.09°C (2709 mK)。",
    "推理步骤 2: 将传感器原始值转换为摄氏度验证：Matter 协议中温度通常以毫开尔文 (mK) 为单位。2709 mK = 2709/1000 - 273.15 ≈ -2.15°C? 不对，重新检查 Matter 标准。Matter TemperatureMeasurement.MeasuredValue 单位是 milliKelvin (mK)。绝对零度是 0 K。室温 25°C = 298.15 K = 298150 mK。日志中的数值如 2269 显然不是 mK。让我们重新审视 Matter 规范或常见实现。在某些简化日志或特定厂商实现中，可能直接记录为整数摄氏度，或者这是一个相对值？不，看数值变化：2269 -> 2840 -> 2709。如果是摄氏度，22.69°C 到 28.40°C 是正常的昼夜温差。但是，如果是 2269 mK，那大约是 -2.15°C，这在夏季室内不可能。如果是 2269 * 100 = 226900 mK (22.69°C)，那么 2709 * 100 = 270900 mK (27.09°C)。这看起来像是正常的室温波动？等等，再看一眼数据：18:00 时厨房温度突然跳到 2390 (23.9°C)，然后 18:02 跳到 2840 (28.4°C)，18:06 跳到 2960 (29.6°C)，18:25 达到 2709 (27.1°C)。如果单位是 mK 且需要除以 100 得到摄氏度，那么 27.1°C 只是略高，不算火灾。但如果单位就是摄氏度呢？22.69°C 到 27.09°C 也是合理的。",
    "推理步骤 3: 必须重新评估“异常”的定义。让我们对比其他房间。卧室从 21.78°C 升到 22.00°C。客厅从 22.69°C 降到 23.18°C。厨房从 22.67°C 升到 27.09°C。这种升温幅度（约 4-5 度）在夏季傍晚（18:00）可能是由于阳光直射、刚做完饭余热或空调关闭导致的。然而，关键在于**速率**。从 18:00 到 18:02，厨房温度在 2 分钟内上升了约 4.5 度（假设单位是某种缩放后的摄氏度）。更重要的是，查看 `kitchen_temp_sensor` 在 18:06 读数为 2960 (29.6°C)，18:15 为 25.77°C，18:20 为 26.33°C，18:25 为 27.09°C。这个趋势显示温度在持续累积热量。虽然 27°C 本身不构成火灾，但结合上下文：用户刚刚锁门离开（18:30 锁门），而在此之前厨房温度正在快速爬升。如果这是灶具过热或电器故障的前兆，仅靠温度传感器可能不够，因为烟雾报警器尚未报警。但是，再仔细看数据：2269, 2405, 2529... 这些数字如果是 mK，除以 1000 是 2.2K，减去 273 是负数。如果是 mK 且基准不同？不，最可能的解释是：**日志中的数值实际上是摄氏度乘以 100 或者直接就是摄氏度的小数点移位错误？** 或者是 **22.69°C**? 如果是 22.69°C，那么 27.09°C 是完全正常的室温。",
    "推理步骤 4: 让我再次仔细检查是否有其他线索。18:30 用户手动锁门。此时所有房间无人（occupancy=0）。如果厨房真的发生了火灾级别的升温（例如 >100°C），传感器通常会损坏或触发联动。目前的最高温是 27.09 (假设单位是 x100 的摄氏度) 或 2709 (如果是 mK 则极低)。",
    "推理步骤 5: **修正推理**：让我们假设日志中的 `MeasuredValue` 单位是 **milli-Celsius (mC)** 即 0.01°C，或者是某些系统为了精度使用的 **0.1°C** 的整数倍？不，Matter 标准是 mK。如果 2269 mK = 2.269 K = -270.85°C，这不可能。如果 2269 代表 22.69°C (即实际值 / 100)，那么 2709 代表 27.09°C。这在夏天是合理的。",
    "推理步骤 6: **是否存在误报风险？** 如果一切正常，为什么标记为异常？让我们看 18:00 到 18:25 的变化。厨房温度从 23.90°C 升至 27.09°C。同时，卧室和客厅温度也在缓慢变化。这看起来像是一个自然的物理过程（太阳下山后余热释放，或者刚关掉的空调/暖气余温）。但是，请注意 **18:02** 厨房温度突增到 28.40°C，而卧室只升到 28.10°C (这里卧室也跳了？18:04 卧室 28.10)。等等，18:04 卧室是 2810 (28.10°C)? 之前是 22xx。这意味着卧室温度也从 22°C 跳到了 28°C？",
    "推理步骤 7: **关键发现**：比较 17:55 和 18:00。17:55 卧室 22.69°C。18:00 卧室 22.29°C。18:02 卧室没数据。18:04 卧室 28.10°C。**卧室温度在 4 分钟内从 22°C 飙升到 28°C**？这在物理上极不可能，除非传感器故障或被加热源直接照射。同样，厨房从 23.9°C 飙升到 28.4°C。这种**短时间内（<5 分钟）跨越 5-6 度的剧烈跳变**，且发生在同一时间段（18:00-18:05），强烈暗示**传感器故障 (sensor_malfunction)** 或 **传感器漂移 (sensor_drift)**，而非真实的火灾风险。真实的火灾升温会更快且更均匀地影响整个空间，或者至少不会让卧室和厨房同时发生如此精确的同步跳变（除非有巨大的热源瞬间出现在两个房间，这在一室一厅里不太可能）。",
    "推理步骤 8: 结论反转：这不是火灾风险，而是**传感器故障**。多个温度传感器在同一时间点出现非物理可能的数值跳变（从 ~22°C 直接跳到 ~28°C），随后又回落或波动。这表明传感器硬件损坏、通信干扰导致的数据包错误，或者是固件 bug。",
    "推理步骤 9: 最终判断：威胁类型为 `sensor_malfunction`。虽然温度升高本身令人担忧，但数据的物理不可能性（短时间跨房间同步剧变）证实了这是设备问题，而非真实环境危险。不过，作为安全助手，不能忽视这种“疑似火灾”的误报可能带来的恐慌，也不能忽视传感器失效可能导致真正的火灾未被检测到的风险。因此，建议检查传感器。",
    "key_evidence": [
      "2026-07-09T18:04:00 卧室温度传感器读数从之前的 ~22°C 级别突变为 2810 (28.10°C)，与前一小时相比无合理热源支持此幅度的瞬时升温。",
      "厨房温度传感器在 18:00 至 18:05 期间也出现了类似的非自然跳变（23.90°C -> 28.40°C），且与卧室跳变时间高度重合，符合多点传感器同时故障的特征。"

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. 排除误报可能性：虽然凌晨 3 点独居老人通常处于睡眠状态（所有房间运动传感器均为 0），但温度传感器数据显示客厅温度从 03:00 的 23.62°C 缓慢上升至 04:45 的 24.31°C。这种缓慢上升更符合环境温度变化或空调关闭后的自然升温，而非火灾导致的急剧温升。然而，烟雾报警器的触发是最高优先级的安全事件，不能仅凭温度未急剧升高就忽略烟雾信号，因为某些类型的燃烧（如阴燃）可能产生大量烟雾而初期热量释放较慢。",
    "3. 结合住户情况评估风险：住户为独居老人，且在凌晨时段发生火警，意味着老人可能无法及时察觉或响应警报。即使最终确认为误报（如烹饪残留、灰尘等），也必须视为真实威胁处理，因为潜在的生命安全风险极高。"

## 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",
  "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": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房烟雾报警器触发，且客厅温度持续异常升高，存在火灾风险。",
  "reasoning": [
    "1. 关键事件触发：日志显示在 03:16:00，厨房烟雾报警器（kitchen_smoke_alarm）的 SmokeState 变为 1（报警状态），同时客厅烟雾报警器（living_room_smoke_alarm）的 InterconnectSmokeAlarm 变为 1，表明系统检测到烟雾并进行了联动报警。",
    "2. 伴随环境异常：在烟雾报警前后，客厅温度传感器读数呈现持续上升趋势，从 01:50 的 23.20°C 上升至 04:45 的 24.19°C（注意：Matter协议中温度单位为厘氏度/0.01°C，故2320代表23.20°C）。虽然绝对值看似不高，但在凌晨时段（03:00-04:00）室内无人活动（所有Occupancy均为0）的情况下，环境温度不应出现如此明显的单向爬升，这通常暗示热源存在或通风不良导致热量积聚。",
    "3. 排除误报可能性：尽管独居老人在凌晨可能未察觉，但烟雾报警是最高级别的安全威胁信号。结合温度传感器的异常波动，不能简单视为传感器故障，必须优先按真实火情处理。"
