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",

  ],
  "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。

  "confidence": "medium",
  "threat_type": "none",

  "threat_description": "厨房灶具开启后，温度传感器检测到数值瞬间飙升（从约 2300 跳变至 2860 及 2740），远超正常烹饪温度范围，疑似发生严重过热或火灾风险。",
  "reasoning": [
    "推理步骤 1: 分析时间线，在 19:00 厨房灶具 (kitchen_cook_surface) 被开启，随后在 19:20 关闭。在此期间，厨房温度传感器读数维持在 2200-2300 区间（对应约 22-23°C，符合 Matter 协议中常见的毫开尔文或特定缩放单位下的室温）。",

    "推理步骤 3: 结合上下文，所有房间 occupancy 均为 0，表明无人干预。如此剧烈的温度读数激增通常意味着传感器检测到了极高热量（如明火、燃气泄漏燃烧）或者传感器本身发生了故障/漂移。考虑到安全优先原则，必须将其视为潜在的火灾风险进行最高级别响应。"
  ],
  "key_evidence": [
    "19:25:00 和 19:35:00 的温度读数 (2860, 2740) 与前后时刻 (2200-2300) 存在巨大且无物理依据的偏差。",
    "事件发生在无人值守 (Occupancy=0) 的情况下，且紧随灶具操作之后。"

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。

  "reasoning": [
    "1. 分析核心事件：日志显示在 14:00 到 14:30 之间，厨房洗碗机（kitchen_dishwasher）从空闲状态变为运行状态（OperationalState=1），并在 14:26 左右设置了倒计时（CountdownTime=1800秒，即30分钟），最后在 14:55 结束运行（OperationalState=0）。这是一个完整的、正常的洗碗机工作周期。",
    "2. 分析关联数据（温度）：在同一时间段内，厨房温度传感器读数从约 24.9°C (2490) 持续下降至最低点 24.34°C (2434)。通常洗碗机工作时会产生热量，导致局部温度升高或波动，但此处温度反而显著下降。",
    "3. 排除安全隐患：虽然温度下降与洗碗机运行看似矛盾，但这更可能是由于以下原因之一：a) 用户打开了窗户或门导致冷空气进入；b) 空调系统正在制冷且位于同一区域；c) 传感器本身存在漂移或故障（Sensor Drift/Malfunction）。然而，日志中并未出现烟雾报警、漏水报警或门锁异常等直接的安全威胁信号。",
    "4. 综合判断：尽管温度数据的趋势值得注意（可能暗示传感器需要校准或环境有通风变化），但在当前的日志片段中，没有证据表明存在入侵、火灾、燃气泄漏或设备故障导致的危险情况。洗碗机的操作符合常规使用模式。因此，判定为无即时安全威胁的正常事件。"

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。

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。

    "3. 结合住户行为：独居老人在上午时段活动正常（客厅、卧室、厨房均有 Occupancy=1 的记录），且没有紧急求助或异常静止的迹象。设备自检通常由用户主动发起或系统定时执行，属于预期内的正常行为。"

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。

  "threat_type": "none",
  "threat_description": "日志显示厨房烟雾报警器正在进行正常的自检程序，且环境数据与人员活动符合日常早晨的生活规律，未检测到安全威胁。",
  "reasoning": [
    "1. 识别核心事件：在 08:00:00 至 08:05:00 期间，厨房烟雾报警器（kitchen_smoke_alarm）的 `TestInProgress` 属性由 True 变为 False，同时 `ContaminationState` 为 0。这表明设备正在执行或刚刚完成一次标准的自检流程，这是智能家居维护中的正常行为，而非火灾报警。",
    "2. 排除误报干扰：虽然烟雾报警器处于测试状态，但同一时间段内（07:37-08:50），厨房窗户传感器、温度传感器均无异常触发，且没有伴随其他房间的运动传感器大规模异常激活或门锁被非法开启的记录，排除了因测试导致系统混乱或掩盖真实入侵的可能性。",
    "3. 验证上下文合理性：日志显示早晨 07:37 有人通过手动方式解锁并离开/进入入户门（LockOperation Manual），随后多个卧室和餐厅出现人员活动（Occupancy=1），这符合家庭成员起床、准备早餐或外出的早晨生活场景。温度读数在 24-25°C 之间波动，属于舒适区间，无过热迹象。"

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。
