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",
  "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": 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": [

  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房温度传感器检测到瞬间异常高温峰值（29.2°C），随后迅速回落，疑似灶具干烧或局部过热引发火灾风险。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-24T12:05:00 时，厨房灶具 (kitchen_cook_surface) 状态变为开启 (True)，此时厨房温度约为 25.2°C，属于正常烹饪升温范围。",
    "推理步骤 2: 仅约 1 分钟后 (2026-08-24T12:12:00)，厨房温度传感器读数从正常的 25.x°C 突增至 29.2°C (即 2920 mK)，这是一个显著的异常尖峰，远超普通烹饪产生的温和升温速率。",
    "推理步骤 3: 该高温峰值在 1 分钟内迅速回落至 25.15°C，这种‘脉冲式’高温特征不符合正常烹饪曲线，更符合油锅起火、燃气泄漏遇明火或设备故障导致的局部剧烈燃烧/过热现象，存在即时火灾风险。"
  ],
  "key_evidence": [
    "2026-08-24T12:05:00 kitchen_cook_surface OnOff.OnOff = True",
    "2026-08-24T12:12:00 kitchen_temp_sensor TemperatureMeasurement.MeasuredValue = 2920 (对应 29.2°C)"
  ],
  "recommended_actions": [
    "立即通知住户检查厨房是否有烟雾、异味或明火，并确认是否已关闭灶具。",
    "建议系统自动触发厨房烟雾报警器测试或联动排风系统。",
    "若住户未响应或确认有险情，应通过 Matter 协议向家庭安防中心发送最高级别警报。"

## 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",

  ],

```

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 2: 关键异常发生在 12:05 之后。灶具于 12:05 开启，但在 12:10 时，客厅运动传感器检测到有人（Occupancy=1），而卧室也检测到有人。然而，从 11:46 到 12:16 期间，厨房区域本身没有明确的‘有人’活动记录（如厨房灯未开，且无厨房占用报告），或者更严重的是，用户可能在操作后离开了厨房区域。",
    "推理步骤 3: 最致命的证据是温度数据。在 12:05 开启灶具后，厨房温度传感器读数从正常的 ~2700K (约 24°C) 急剧飙升至 2920K (约 26.8°C) 甚至更高（之前曾达到 2936K）。这种在高温烹饪设备开启时的快速升温，结合可能的无人看管（Unattended Cooking）场景，是典型的火灾隐患前兆。此外，11:47 出现的 'None' 温度读数可能暗示传感器故障或信号中断，增加了不确定性，但随后的持续高温读数确认了热积聚现象。",
    "推理步骤 4: 综合判断，灶具开启后温度持续攀升且未见及时关闭或降温迹象，符合‘无人看管烹饪’导致的火灾风险特征。"

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。

请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

请按以下 JSON 格式回答：

```json

  "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
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

  "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",

    "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": "检测到洗碗机启动并运行，同时厨房温度逐渐下降，符合正常家电使用及环境调节行为，未发现安全风险。",
  "reasoning": [
    "1. 分析核心设备状态：日志显示 kitchen_dishwasher 在 14:00 进入 OperationalState=1 (运行中)，并在 14:30 设置 CountdownTime=1800秒 (30分钟)，最后在 14:55 变为 OperationalState=0 (完成/停止)。这构成了一个完整的、时长约55分钟的洗碗机工作周期，属于正常的家务活动。",
    "2. 分析环境数据关联：厨房温度传感器数据显示温度从 13:00 的 27.45°C 持续下降至 15:15 的 24.24°C。这种降温趋势通常由空调开启或开窗通风引起。考虑到客厅和卧室 occupancy 传感器多次报告有人 (Occupancy=1) 或无人 (Occupancy=0) 的状态变化，且客厅 occupancy 在洗碗机运行时保持为 1，推测住户可能在客厅活动并开启了空调，导致整体室温（包括厨房）下降。",
    "3. 排除异常模式：没有检测到烟雾报警、漏水、门锁异常开启或长时间无人居住等危险信号。洗碗机的启停逻辑清晰，温度变化平缓且合理，未出现传感器卡死 (stuck) 或漂移 (drift) 的迹象（数值连续变化）。因此，判定为正常家庭行为。"
  ],
  "key_evidence": [
    "kitchen_dishwasher OperationalState 从 1 变为 0，中间包含 CountdownTime 设置，符合标准洗涤流程。",
    "kitchen_temp_sensor 温度值随时间持续稳定下降 (2745 -> 2424)，无突变或停滞，反映环境温度正常调节。",
    "living_room_occupancy 在洗碗机工作期间保持为 1，表明家中有人活动，排除了无人看管导致的潜在风险。"
  ],
  "recommended_actions": [
    "无需采取任何安全措施。",

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。
