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
监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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。

{
  "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: 正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "key_evidence": [
    "正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在灶具开启后出现严重数据漂移，读数异常飙升（29.2°C）且随后无法回落至正常范围，疑似传感器故障或校准错误。",
  "reasoning": [
    "推理步骤 1: 在 2026-07-02T12:05:00，厨房灶具 (kitchen_cook_surface) 被开启，此时厨房温度传感器读数为正常的 25.24°C。",
    "推理步骤 2: 仅仅 5 分钟后 (12:12:00)，同一传感器的读数突然跳变至 2920 (即 29.2°C)。考虑到刚开启的灶具通常不会在 5 分钟内使整个厨房环境温度升高近 4 度，且该数值远超物理常识中的室温上限，这属于典型的传感器数据异常。",
    "推理步骤 3: 随后的日志显示，尽管时间推移到 12:20:00，该传感器读数虽然有所回落但仍停留在 25.26°C 附近，未能恢复到与客厅 (约 25.1°C) 一致的基线水平，表现出明显的‘漂移’或‘卡滞’特征，而非正常的动态变化。这种不一致性表明传感器本身可能已损坏、校准失效或被干扰，导致其报告的数据不可信。"
  ],
  "key_evidence": [
    "2026-07-02T12:12:00 kitchen_temp_sensor 读数从 ~25°C 瞬间跳变为 29.2°C (2920 mK)。",
    "灶具开启后短时间内室内环境不可能产生如此剧烈的温升，且后续读数未回归合理波动范围。"
  ],
  "recommended_actions": [
    "立即通知用户检查厨房温度传感器硬件状态，建议重新校准或更换设备。",
    "暂时忽略该传感器的温度报警逻辑，避免误报火灾风险，直到传感器修复。",
    "建议用户手动确认厨房实际温度，以防因传感器故障掩盖真实的过热情况。"

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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: 正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "key_evidence": [
    "正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房灶具在无人看管的情况下开启，且伴随温度传感器读数异常飙升（疑似故障或极端过热），存在严重火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-07-19T12:05:00 时，厨房灶具 (kitchen_cook_surface) 状态变为 True (开启)。",
    "推理步骤 2: 此时及随后的一段时间内 (12:05 - 13:00)，所有房间的运动传感器 (occupancy_sensor) 均报告 Occupancy = 0，表明厨房区域无人，属于典型的‘无人看管烹饪’场景。",
    "推理步骤 3: 关键异常点在于 2026-07-19T12:12:00，厨房温度传感器读数从正常的 ~2500 (约 25°C) 瞬间跳变至 2920 (约 29.2°C 或更高，取决于单位换算逻辑，但相对于环境是剧烈波动)，随后又回落。这种剧烈的温度读数变化结合灶具开启和无人状态，极可能是传感器检测到局部高温（如起火前兆）导致的读数漂移，或者是传感器本身故障导致误报高温，无论哪种情况，都构成了极高的火灾隐患。",
    "推理步骤 4: 综合来看，无人状态下开启热源设备，且温度数据出现不可解释的剧烈波动，符合火灾风险的典型特征。"
  ],
  "key_evidence": [
    "2026-07-19T12:05:00 kitchen_cook_surface OnOff.OnOff = True",
    "2026-07-19T12:12:00 kitchen_temp_sensor TemperatureMeasurement.MeasuredValue = 2920 (异常高值)",
    "2026-07-19T12:05:00 至 13:00:00 期间所有 occupancy_sensor 均为 0 (无人)"
  ],
  "recommended_actions": [
    "立即通过 Matter 协议远程关闭厨房灶具 (kitchen_cook_surface)。",
    "检查厨房烟雾报警器 (smoke_co_alarm) 是否已触发，并确认现场是否有火情。",
    "重置或校准厨房温度传感器 (kitchen_temp_sensor)，排查硬件故障。",
    "若确认无火情，建议用户在未来设置‘无人自动关火’规则。"

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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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": [
    "步骤 1: 分析时间线，用户在 06:50-07:52 和 12:05-12:12 进行了两次烹饪活动。第一次烹饪后，厨房温度从约 25°C 缓慢下降至 24°C 左右，符合正常散热规律。",
    "步骤 2: 第二次烹饪于 12:05 开始，结束于 12:12。此时厨房温度应处于高温但随后应开始下降。然而，在 12:12:00，厨房温度传感器报告值为 2920 (即 29.20°C 或原始单位下的异常高值，考虑到其他房间为 25xx，此处极可能是 29.20 的误报或传感器彻底损坏导致的溢出/跳变)。",
    "步骤 3: 对比同一时刻的其他设备：客厅、主卧、次卧的温度均在 25xx 范围内（约 25.2°C - 25.4°C），且变化平稳。厨房温度瞬间跳升至 2920 并迅速回落至 2522，这种剧烈的非物理性波动排除了火灾风险（如果是真实火灾，温度会持续上升且伴随烟雾报警），确认为传感器硬件故障或软件逻辑错误（Sensor Malfunction）。",
    "步骤 4: 该故障可能导致基于此传感器的自动化场景（如联动空调、烟雾报警误判）失效或产生误动作，属于需要立即处理的安全隐患。"

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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。

    "2. 排除真实威胁：虽然涉及烟雾报警器，但状态明确标记为 'TestInProgress'（测试进行中），而非 'FireDetected' 或 'SmokeDetected'。且两个区域的报警器几乎同时触发并结束，符合用户手动按下测试按钮或系统自动执行定期自检的特征，而非随机发生的火灾报警。",
    "3. 结合环境背景：在此期间（09:00-10:25），家中多个房间（卧室、厨房、玄关、客厅）的运动传感器持续报告有人活动（Occupancy=1），表明住户处于清醒和活动状态，排除了因突发事故导致无人知晓的情况。温度数据也在正常范围内波动，未出现异常升温。",

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。

  "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",

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",
  "threat_description": "一句话描述发现的问题或确认安全",

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。

    "2. 分析环境传感器数据：厨房温度传感器读数从 25.01°C 缓慢下降至 24.17°C，变化趋势平滑且幅度合理（约1度/小时），属于正常的室内温度波动或空调调节结果，未发现火灾风险所需的急剧升温。",
    "3. 分析人员活动模式：多个房间（玄关、餐厅、儿童房、主卧等）的运动传感器在下午时段频繁触发（Occupancy=1），表明家中有人活动。结合时间（13:00-16:00）和地点分布，符合家庭成员日常居家活动的特征，无长时间无人值守导致的潜在风险（如忘记关火），也无入侵者常见的夜间或长时间静止异常。"
