## 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。

    "对比同一时间段内的其他设备：客厅温度传感器在17:00为24.40°C，厨房为23.65°C，均处于正常室温区间，未出现同步升温。这表明并非环境整体温度突变，而是单一设备读数异常。",
    "考虑到独居老人的安全背景，虽然29.2°C本身不构成直接的生命危险（如火灾或一氧化碳中毒），但这种剧烈的数据波动属于硬件故障、电池电量不足导致的采样错误或通信干扰引起的数据包错误。对于依赖传感器数据进行健康或环境监测的系统来说，这是不可靠的信号。"

## 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",

  ],
  "recommended_actions": [

}
```

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": [
    "推理步骤 1: 分析时间线发现，从凌晨 05:55 开始，厨房温度传感器读数急剧上升（2435 -> 2488），并在上午 07:30 达到峰值 2527 (约 22.9°C * 100 = 22.9°C? 不，Matter 通常单位是 0.01°C，即 25.27°C，但结合上下文看，如果是摄氏度直接记录可能是 25.27，如果是毫开尔文或其他单位则不同。让我们重新校准：通常 Matter TemperatureMeasurement.MeasuredValue 单位是 0.01°C。2263 = 22.63°C。2527 = 25.27°C。这个温升幅度对于室内环境来说虽然不算极端高温，但需要结合其他因素。)",
    "修正推理步骤 1: 重新审视数据趋势。厨房温度从 05:55 的 24.35°C 持续攀升至 07:45 的 25.27°C，随后在 08:25 降至 25.34°C 后波动。虽然绝对温度未达报警阈值（通常>60°C），但需关注相对变化和设备状态。",
    "推理步骤 2: 关键证据在于 `kitchen_cook_surface` 的状态。日志显示在 06:37:00 灶具状态变为 `False` (关闭)，但在随后的 06:40:04、07:00:04、07:25:04、08:20:04 等多个时间点，`kitchen_occupancy` 均检测到有人 (`Occupancy = 1`)。",
    "推理步骤 3: 结合独居老人背景，出现“灶具已关闭”但“厨房内仍有人员长时间停留并伴随温度持续微幅爬升”的情况，极有可能是老人忘记关火或灶具故障导致余热积聚，或者更危险的是：灶具实际上并未完全熄灭（传感器误报关闭），而人员因某种原因（如身体不适、注意力不集中）未及时离开或处理。考虑到温度在无人干预下持续缓慢上升且人员反复进出，存在潜在的烹饪安全事故隐患。",
    "推理步骤 4: 进一步观察，06:37 关闭灶具后，直到 07:18 才检测到入户门有人进入，中间有 40 分钟的时间窗口。在此期间厨房温度持续上升，若灶具真的关闭了，温度应趋于稳定或下降；若温度持续上升，说明热源仍在，这与 `OnOff=False` 的记录矛盾，暗示设备状态可能不准确或存在隐蔽的热源泄漏。"
  ],
  "key_evidence": [
    "06:37:00 厨房灶具报告关闭 (OnOff=False)，但随后多次检测到厨房有人 (Occupancy=1)。",
    "06:37 至 08:25 期间，尽管灶具报告显示关闭，厨房温度传感器读数呈现非自然的持续上升趋势 (24.35 -> 25.27 -> 25.34)，与预期冷却趋势不符。",
    "独居老人在厨房活动期间缺乏即时的人工确认机制，增加了安全隐患。"

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",

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。

    "1. 分析温度数值范围：日志中大部分温度读数为 2300-2600 之间。在 Matter 协议的温度测量 Cluster (0x0300) 中，MeasuredValue 通常以厘氏度（centi-degrees Celsius）为单位存储，即除以 100 得到摄氏度。因此，2500 代表 25.00°C，这是正常的室内环境温度。",
    "2. 识别异常点：在 [2026-08-18T14:05:00]，living_room_temp_sensor 报告 MeasuredValue = -500。这对应于 -5.00°C。考虑到同一时间段其他房间（如主卧、厨房）的温度均在 24°C 左右，且客厅此前为 24.3°C，突然降至 -5°C 极不符合物理规律，除非房屋遭遇极端灾难性事件，但这与其他传感器数据矛盾。",
    "3. 确认故障模式：该异常值 (-500) 出现在正常波动序列中，随后数值又恢复至 2440 (24.4°C)。这种瞬间的、大幅度的、非环境因素导致的数值跳变是典型的传感器硬件故障、ADC 转换错误或数据包损坏迹象。"

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",

    "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。

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：

  "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。

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。
