## 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",

  "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。"

## 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",

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. 温度数据分析：日志中的 `TemperatureMeasurement.MeasuredValue` 数值（如 2540, 2261）符合 Matter 协议标准，单位为厘氏度（cH°C）。例如 2540 cH°C = 25.4°C，2261 cH°C = 22.61°C。这些数值反映了从早晨到傍晚室内温度的自然波动（受日照、空调或人体活动影响），变化趋势平滑且合理，无突变或超出物理极限的异常值。",
    "2.  occupancy 模式分析：各房间的运动传感器（occupancy_sensor）在白天时段（12:00-19:55）频繁触发为 '1'（有人），且在卫生间等短暂停留区域有 '0'（无人）的记录，这符合独居老人在家中日常活动（如做饭、休息、如厕）的行为逻辑。没有发现长时间静止不动导致的‘异常不活动’警报，也没有非正常时间的入侵迹象。",
    "3. 设备协同与一致性：客厅、卧室、厨房的温度传感器读数之间存在一定的温差（如卧室较凉，客厅受阳光或活动影响较热），这是正常的建筑热工现象。同时，运动传感器的活跃时间与温度变化的时间段大致吻合（如中午至下午活动较多，温度略有上升后随时间回落），表明设备工作正常且数据可信。"

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数严重偏离物理现实，显示异常高温（约 254°C），而卧室温度正常且呈下降趋势，表明传感器存在漂移或故障。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 09:00 到 11:50，living_room_temp_sensor 的 MeasuredValue 持续在 2535-2554 之间波动。由于 Matter 协议中温度通常以 0.01°C 为单位，该数值换算后约为 25.35°C - 25.54°C。虽然这个数值本身在舒适范围内，但需结合上下文判断其合理性。",
    "推理步骤 2: 对比同一时间段内的 bedroom_temp_sensor 数据（如 12:20 为 24.31°C，15:00 为 23.40°C），卧室温度随时间自然下降，符合独居老人白天活动、夜间休息或空调运行的正常热力学规律。",
    "推理步骤 3: 关键异常点出现在 17:00:00。此时 living_room_temp_sensor 突然跳变至 2580 (25.80°C)，紧接着在 17:15:00 又跳回 2261 (22.61°C)。这种在短时间内剧烈震荡且与卧室温度变化趋势不一致（卧室在持续缓慢下降）的现象，排除了环境温度突变的可能性，极大概率是传感器校准失效、信号干扰导致的读数漂移（Drift），或者是设备固件 Bug 导致的数值溢出/错误报告。考虑到用户是独居老人，错误的温度反馈可能导致空调系统误判（例如认为太冷而过度制冷，或反之），属于潜在的安全隐患。",
    "修正推理：重新审视数值范围。若 MeasuredValue = 2540 代表 25.40°C，则全天大部分时间客厅温度都在 25°C 左右，这本身是正常的室温。但是，观察 17:00 的数据：Living Room 瞬间变为 25.80°C，随后迅速回落。更关键的异常在于 **17:00 之前** 的数据稳定性与 **17:00 之后** 的剧烈变化。实际上，最大的疑点在于 **17:00:00** 这一时刻，Living Room 和 Bedroom 同时上报了极高的数值（2580 和 2520? 不，Bedroom 是 2580，Living Room 是 2520）。等等，让我再次仔细核对 17:00 的行。",
    "最终确认推理：在 17:00:00，日志显示 `bedroom_temp_sensor` 为 2580 (25.80°C) 和 `living_room_temp_sensor` 为 2520 (25.20°C)。这两个值相对于之前的趋势（卧室一直在降，客厅一直在微降）来说，出现了异常的回升。特别是卧室温度在 16:40 还是 22.80°C，17:00 突然变成 25.80°C，温差巨大且无合理解释（如刚进入房间未稳定即上报？但 occupancy 也是 1）。这种非线性的、违背热惯性规律的突变，被判定为 Sensor Drift（传感器漂移）或 Malfunction（故障）。",
    "再次修正：仔细看 17:00 的那一行：`[2026-07-08T17:00:00] bedroom_temp_sensor | ... = 2580` 和 `[2026-07-08T17:00:00] living_room_temp_sensor | ... = 2520`。之前的卧室温度是 22.80 (16:40) 和 22.93 (16:15)。从 22.8 跳到 25.8 是非常反常的。同时，客厅从 23.79 (16:20) 跳到 25.20。这种同步的、大幅度的温度回升，在没有人员大量聚集（occupancy 均为 1）的情况下，极有可能是传感器故障或数据漂移。",
    "结论：尽管 25°C 左右的温度对人类来说是舒适的，但在智能家居安全分析的语境下，传感器读数的**突变性**和**违背物理规律的趋势反转**（持续降温后突然大幅升温）构成了异常模式。对于独居老人，不可靠的温度数据可能导致温控设备失效，引发过热或过冷风险。"

  "key_evidence": [
    "在 17:00:00，bedroom_temp_sensor 读数从正常的 ~22.8°C 突增至 25.8°C，living_room_temp_sensor 也从 ~23.8°C 突增至 25.2°C。",
    "该突变发生在无人进入新区域（occupancy 保持为 1）的情况下，且与之前数小时持续缓慢降温的热力学趋势完全相反。",
    "Matter 协议下的温度传感器出现此类非线性跳变，通常指示硬件故障、校准丢失或通信干扰导致的读数漂移。"

## 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",

    "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: 正常样本窗户/窗帘状态变化一致；异常样本存在重复矛盾读数。"
  ],
  "key_evidence": [
    "正常样本窗户/窗帘状态变化一致；异常样本存在重复矛盾读数。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{

  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器出现数据丢失（None）及数值异常波动，且与灶具状态无合理关联，疑似设备故障或校准失效。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-04T06:37:00 时刻，厨房温度传感器报告了 'MeasuredValue = None'，这是典型的通信中断、供电不稳或内部固件崩溃导致的传感器故障特征。",
    "推理步骤 2: 尽管随后传感器恢复了读数，但数值出现了非物理性的剧烈跳变（从 2506 瞬间变为 2520，随后在 2520-2549 之间高频震荡），这种不稳定的读数模式不符合正常热力学变化规律。",
    "推理步骤 3: 结合住户为独居老人，厨房是火灾高风险区域，一个不可靠的温度传感器可能导致烟雾报警器误报（因高温触发）或在真实火情下漏报，构成严重的安全隐患。"
  ],
  "key_evidence": [
    "2026-08-04T06:37:00 kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None",
    "2026-08-04T06:37:00 至 08:55:00 期间，厨房温度读数在极短时间内频繁大幅波动（如 2506 -> 2520 -> 2519 -> 2520...），缺乏平滑过渡。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的电池电量及物理连接是否松动。",
    "联系 Matter 设备管理员或厂商重置该传感器，并重新校准其温度阈值。",
    "在修复前，建议人工定期目视检查厨房是否有过热迹象，以防传感器失效导致火灾风险未被及时发现。"

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
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": "客厅灯光及环境传感器数据符合正常晚间居家活动模式，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. 灯光控制逻辑正常：日志显示在 20:10 开启客厅主灯并设置亮度为 180（约70%），随后在 20:18 将亮度调低至 30（约12%）。这种‘先开亮后调暗’的操作符合用户准备休息或观看电视时的典型行为习惯，属于正常的用户交互，而非设备卡死或异常闪烁。",
    "2.  occupancy 状态与时间匹配：从 14:21 至 21:56，客厅运动传感器持续报告 Occupancy = 1，表明客厅内有人活动。结合时间点（下午至深夜），这符合家庭成员在客厅休闲、用餐或活动的常态，未出现长时间无人却误报有人，或有人却无感知的异常情况。",
    "3. 温度数据趋势合理：客厅温度从 14:15 的 24.57°C 逐渐下降至 22:00 的 22.46°C。这一降温过程与傍晚时段室外气温降低以及可能的空调运行有关，数值变化平滑且符合物理规律，未见传感器漂移或故障导致的突变。"

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
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": "阳台洗衣机按正常程序运行，状态变化符合预期，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. 识别关键事件：日志显示在 2026-08-15T10:00:00，阳台洗衣机（balcony_laundry_washer）的 OperationalState 变为 1（通常表示开始运行或处于活动状态）。",
    "2. 验证运行时长与倒计时逻辑：在 T10:20:00，CountdownTime 为 2400秒（40分钟）；在 T10:40:00，CountdownTime 为 1200秒（20分钟）。这表明设备正在执行一个标准的洗涤周期，且剩余时间随时间推移线性减少，符合正常家电工作逻辑。",
    "3. 确认任务完成：在 T11:00:00，OperationalState 变回 0（停止/空闲），此时距离开始运行正好过去了1小时，与之前的倒计时逻辑吻合（假设初始设定可能略长于实际运行或包含其他阶段，但整体流程完整）。",
    "4. 排除异常模式：在此期间，没有检测到入侵传感器触发、漏水报警或烟雾报警等关联风险事件。所有温度传感器读数也在合理范围内波动，未出现极端值。"

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",
  "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: 正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "key_evidence": [
    "正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"

  "threat_description": "客厅温度传感器在 17:00 出现严重数据跳变，从正常范围突增至异常高温值，且随后未回落，表明传感器可能故障或校准失效。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，在 2026-07-31T17:00:00 之前，living_room_temp_sensor 的温度读数（MeasuredValue）稳定在 2200-2400 之间（对应约 22-24°C），符合独居老人夏季的正常居住环境温度。",
    "推理步骤 2: 在 2026-07-31T17:00:00 这一时刻，该传感器报告了三个连续读数：2358、2520 和 2580（对应约 23.6-25.8°C）。虽然 2520 略高，但结合同时间 bedroom_temp_sensor 的读数（2580，约 25.8°C）来看，两者同时升高可能是环境因素，但需进一步观察后续趋势。",
    "推理步骤 3: 关键异常在于 17:00 之后的数据。尽管卧室温度在 17:20 回落到 2242（约 22.4°C），显示卧室环境恢复正常，但客厅温度传感器在 17:45 仍报告 2336，而在 19:25 仅降至 2274。更严重的是，对比同一时间段其他房间传感器的线性变化，客厅传感器在 17:00 后的数值波动幅度与物理规律不符（例如从 2520 到 2580 再到 2336 的非平滑过渡），且考虑到 Matter 协议中 TemperatureMeasurement.MeasuredValue 通常以 0.1°C 为单位（即 2272=22.72°C），17:00 时的 2520 (25.2°C) 和 2580 (25.8°C) 相对于之前的 2358 (23.58°C) 出现了非自然的阶梯式跳跃，且未能随空调或自然通风逻辑平滑回归基线，极大概率是传感器硬件故障或通信干扰导致的读数漂移/卡死。",

      "2026-07-31T17:00:00 时 living_room_temp_sensor 读数从 ~23.6°C 突增至 ~25.2°C，随后在 17:20 卧室温度已回落至 ~22.4°C 的情况下，客厅温度仍未同步显著下降，表现出与其他房间不一致的异常热惯性。",
      "传感器读数序列 (2358 -> 2520 -> 2580 -> 2336) 缺乏平滑的物理过渡特征，呈现典型的传感器故障跳变模式。"

    "recommended_actions": [
      "立即检查客厅温度传感器的物理状态，确认是否被遮挡、损坏或受到外部热源干扰。",
      "联系设备供应商进行固件更新或硬件更换，因为该传感器无法准确反映真实环境温度，可能导致老人中暑风险判断失误。",
