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",

    "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。

  "reasoning": [
    "温度传感器数据合理性分析：所有房间的温度传感器（如 living_room_temp_sensor, kitchen_temp_sensor 等）报告的值均在 2491 到 2559 之间。考虑到 Matter 协议中 TemperatureMeasurement.MeasuredValue 通常以 0.01°C 为单位，这些数值对应约 24.91°C 至 25.59°C，属于夏季室内正常的室温范围，无过热或传感器漂移迹象。",
    " occupancy 传感器逻辑一致性：入户门、客厅、儿童房等关键区域的运动传感器在大部分时间报告 Occupancy = 0，这与早晨 7:00 至中午 13:30 住户可能外出或处于非活动状态的时间段相符；同时没有检测到入侵行为（如无人时门窗被打开）。",
    "重点设备状态验证：阳台洗衣机 (balcony_laundry_washer) 在 10:00 报告 OperationalState = 1 (运行中)，随后多次报告 CountdownTime = 2400 (剩余 40 分钟)，表明设备正在按计划执行洗涤程序，未出现卡死或错误状态。",
    "缺乏危险信号：厨房烟雾报警器、漏水传感器等安全设备未在日志中触发报警事件，且环境温湿度数据稳定，排除了火灾、漏水或一氧化碳泄漏的风险。"
  ],
  "key_evidence": [
    "所有温度传感器读数稳定在 24.9°C - 25.6°C 的正常区间内。",

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: ..."
  ],

    "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": "sensor_malfunction",
  "threat_description": "厨房温度传感器出现数据丢失（None）及随后数值异常跳变，疑似硬件故障或通信中断。",
  "reasoning": [
    "1. 观察日志时间线：在 2026-07-10T19:13:00，厨房温度传感器上报 `TemperatureMeasurement.MeasuredValue = None`，表明该时刻传感器未能提供有效读数，可能处于离线、重启或通信失败状态。",
    "2. 紧接着在 2026-07-10T19:15:00（仅2分钟后），同一传感器上报数值为 2298。结合前后文，19:10时儿童房温度为2300，19:20时为2292，19:40时厨房恢复后为2282。虽然2298在合理范围内，但之前的'None'值是一个明确的故障信号。",
    "3. 对比其他设备：在同一时间段内，客厅、主卧、儿童房的温度传感器均正常上报连续且符合物理规律（缓慢下降）的数值。唯独厨房传感器出现中断，排除了全屋网络波动导致所有传感器同时失效的可能性。",
    "4. 结论：这种间歇性的数据丢失（Null/None）是典型的传感器通信模块不稳定或内部电路故障的表现，属于设备健康问题。"
  ],
  "key_evidence": [

  ],
  "recommended_actions": [
    "检查厨房温度传感器的电池电量或电源连接情况。",
    "尝试重新配对或重置该传感器，若问题持续存在，建议更换设备。",
    "监控后续日志，确认是否再次出现 'None' 值或数值剧烈跳变。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "low",
  "threat_type": "intrusion",
  "threat_description": "存在异常，但原因更可能属于其他类别。",
  "reasoning": [

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": "high",

    "1. 分析重点设备日志：在 09:10:00 到 09:12:00 之间，客厅窗户传感器 `living_room_window_contact` 的状态发生了剧烈变化。",
    "2. 具体异常模式：09:10:00 时状态为 True (关闭/闭合)，仅2分钟后即 09:12:00 变为 False (打开/断开)。紧接着在 09:15:00，窗帘执行器 `living_room_window` 被操作至位置 0 (通常代表完全关闭)，但此时窗户传感器并未立即反馈为 True，或者在后续日志中未看到明确的稳定闭合确认（虽然日志截断，但之前的快速跳变已构成疑点）。",
    "3. 排除正常行为：用户不太可能在2分钟内反复开关窗户两次（开-关-开），且没有伴随其他明显的交互行为（如灯光开启、人员移动等）来佐证这一高频操作。这种短时间的状态不稳定（Flapping）是典型的传感器硬件故障、磁铁脱落或通信干扰特征。",
    "4. 结合上下文：同一时间段内温度传感器读数平稳上升，无火灾或极端环境迹象；门锁操作发生在早上7点多，与本次异常无关。因此，问题集中在窗户传感器本身的稳定性上。"

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",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",

}
```

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。

    "推理步骤 3: 尽管日志中显示灶具在 11:31 关闭，但在关闭前长达数小时的持续高温表明可能存在未察觉的明火、燃气泄漏燃烧或设备故障导致的过热，对于独居老人而言这是严重的安全隐患。"

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

  "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. 分析温度数值范围：日志中所有温度传感器的 `MeasuredValue` 均在 2268 到 2559 之间。在 Matter 协议标准中，`TemperatureMeasurement` Cluster 的 `MeasuredValue` 通常以厘度（centi-degrees Celsius）为单位，即除以 100 得到摄氏度。若按此标准，2270 代表 22.7°C，这是非常正常的室内温度。然而，如果该设备固件实现有误，直接上报了华氏度（Fahrenheit）或未经缩放的原始 ADC 值，则 22-25°C 的范围完全不合理（相当于 70-77°F，虽然数值上接近，但整数部分差异巨大；或者如果是原始值，2200+ 对于任何常见温度单位都过高）。",
    "2. 观察变化趋势与逻辑矛盾：从凌晨 00:00 到上午 12:35，温度读数呈现持续、单调上升的趋势（从 ~2270 升至 ~2550）。在夜间至清晨时段，室外气温通常较低或保持平稳，室内温度不应在没有加热源开启的情况下持续线性上升超过 20-30 个单位。这种违背热力学常识的持续上升趋势表明传感器可能存在校准漂移、固件 Bug 或数据上报格式错误。",
    "3. 结合 occupancy 状态排除人为干扰：尽管主卧和卫生间有人员活动（Occupancy=1），但这些活动并未伴随空调或加热设备的明显控制日志（日志中主要展示的是传感器读数和简单的开关灯/门锁状态，未见 HVAC 调节日志）。即使考虑人体散热，如此大范围、全房间、长时间的温度同步异常升高更指向传感器本身的系统性问题，而非局部热源。"

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。
