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
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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: ..."
  ],

    "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: 正常入户会伴随门磁、玄关灯或入口相关活动；异常样本只有解锁结果和室内后续活动。"
  ],
  "key_evidence": [
    "正常入户会伴随门磁、玄关灯或入口相关活动；异常样本只有解锁结果和室内后续活动。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房温度传感器检测到异常高温（超过 260°C），且伴随灶具开启事件，存在严重的火灾风险。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-25T19:03:30 记录到厨房灶具 (kitchen_cook_surface) 被开启，随后厨房温度开始急剧上升。",
    "推理步骤 2: 从 19:05 开始，厨房温度传感器读数迅速攀升至 2424、2478、2538，并在 19:20 达到 2610，19:30 达到 2676。这些数值远超正常烹饪环境或设备故障的合理范围（通常摄氏度单位下 >100 即为沸腾，>200 已接近金属熔点，此处极可能是数据漂移或严重过热导致的极端读数）。",
    "推理步骤 3: 尽管客厅和卧室温度正常，但厨房作为热源区域出现如此离谱的高温读数，结合烟雾报警器 (smoke_co_alarm) 的存在，表明可能存在燃气泄漏燃烧失控、油锅起火或传感器因高温/故障而报告了致命错误值，必须视为最高级别的火灾隐患。"
  ],
  "key_evidence": [
    "2026-08-25T19:03:30 kitchen_cook_surface | OnOff.OnOff = True (灶具开启)",
    "2026-08-25T19:30:00 kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2676 (异常高温)"
  ],
  "recommended_actions": [
    "立即通知住户撤离厨房并关闭总电源/气源。",
    "检查厨房是否有明火、浓烟或焦糊味。",
    "若确认无火情，需立即更换厨房温度传感器并排查灶具线路及燃气安全。",
    "建议触发家庭警报系统或联系紧急服务部门进行核实。"

## 任务
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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。

    "1. 入户门安全分析：日志中仅出现一次 `front_door_lock` 上锁事件（07:05），且发生在早晨时段，结合 `front_door_contact` 在 07:22 显示关闭（False通常代表关闭/锁定状态，需结合具体实现，但此处无非法开启记录），以及后续几天无异常的门锁操作或入侵迹象，表明入户门处于受控状态。没有检测到暴力破解、多次失败尝试或非授权时段的开启行为。",
    "2. 人员活动模式分析：客厅和卧室的运动传感器数据显示了典型的居家作息模式。早晨（07:18-08:30）卧室有人活动，随后客厅在傍晚（18:00后）及夜间频繁检测到人员存在（Occupancy=1），符合下班回家后的活动规律。没有出现长时间无人却触发警报的误报，也没有出现深夜异常活跃或清晨过早活动的可疑行为。",
    "3. 环境与设备状态分析：温度传感器读数随时间自然波动（如白天升温、夜晚降温），数值在合理范围内（21-25摄氏度左右）。厨房洗碗机在晚间启动（18:36, 18:41）属于正常的家电使用行为。未发现烟雾报警器触发、漏水传感器报警或灶具长时间无人看管等危险信号。"

    "温度数据平稳过渡，无剧烈突变；洗碗机在常规晚餐后时间段运行，无安全隐患。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需采取紧急干预措施。",

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。

  "threat_description": "未检测到安全威胁，日志显示为住户正常下班回家及在室内活动的行为模式。",
  "reasoning": [
    "1. 分析入户事件：18:03:00 门锁执行上锁操作（LockState=2），随后门磁传感器显示门关闭（False）。紧接着玄关灯亮起（18:03:10）且客厅 occupancy 变为有人（18:03:16）。这符合典型的‘进门后反锁’或‘从外部进入并立即确认安全’的行为逻辑，属于正常居家行为。",
    "2. 分析后续状态：18:40:00 门锁再次显示为锁定状态（LockState=2），此时门磁为 False（门关）。这表明住户在屋内活动期间，门锁保持安全锁定状态，没有发生非法入侵导致的异常开锁或门未关严的情况。",
    "3. 排除误报可能：虽然 18:41:00 门磁短暂显示 False（通常代表关门/闭合，但在某些协议中 False 可能代表断开，需结合上下文。此处结合前文 07:28 的开门流程：Open=True, Close=False? 或者 Open=False, Close=True? 让我们重新校准逻辑。通常 Contact Sensor: Open=True (断开), Closed=False (闭合)。回顾 07:28: Lock(1->2, 锁上) -> Contact(False, 关?) -> Contact(True, 开?) -> Lock(2->1, 开?)。这里 07:28 的逻辑有点奇怪，如果是出门，应该是 Unlock -> Open Door -> Lock。日志显示 Lock(1->2) 是锁上，Contact(False) 可能是初始状态，然后 Contact(True) 是开门？不，通常 True 是 Open。如果 07:28 是出门，应该是先 Unlock。日志里 07:28 只有 Lock 操作。这可能是用户早上出门没带钥匙反锁？或者日志筛选有偏差。但重点看 18:03。18:03 Lock(1->2) 是锁上。Contact(False) 是关门。Light On。Occupancy 1。这是标准的回家反锁。18:40 Lock State 2 (Locked)。Contact False (Closed)。这也是安全的。整个过程中没有发现非授权开锁、门长时间未关、或夜间异常闯入的迹象。"

## 任务
请从下面的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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: 正常入户会伴随门磁、玄关灯或入口相关活动；异常样本只有解锁结果和室内后续活动。"
  ],
  "key_evidence": [

  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器数据严重漂移且丢失，伴随灶具开启，存在极高的火灾风险或设备故障隐患。",
  "reasoning": [
    "推理步骤 1: 在 2026-07-29T19:05:30 用户开启厨房灶具后，厨房温度传感器读数开始异常飙升（从正常的 23°C 左右迅速上升至 2673），这远超物理可能的室温范围，表明传感器数值读取错误而非真实环境温度升高。",
    "推理步骤 2: 在 2026-07-29T19:06:00 及随后一段时间内，该传感器返回了 None 值，显示通信中断或数据上报失败，这是典型的传感器故障或网络丢包特征。",
    "推理步骤 3: 结合住户正在使用灶具（cook_surface=On）这一高风险场景，如果烟雾报警器（smoke_co_alarm）因传感器故障未能联动或无法准确判断环境状态，将导致严重的消防安全盲区。虽然日志中未直接显示烟雾报警触发，但温度数据的极端异常是明确的设备故障信号。"
  ],
  "key_evidence": [
    "2026-07-29T19:05:30 开启灶具后，厨房温度传感器读数在短时间内从 ~23°C 激增至 2673。",
    "2026-07-29T19:06:00 厨房温度传感器报告值为 None，随后多次出现非正常的高数值（如 2495, 2547, 2619）。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的硬件连接和供电情况，确认是否损坏。",
    "手动检查厨房是否有烟雾、异味或过热现象，确保人员安全。",
    "在修复传感器前，建议暂时关闭自动温控联动，并人工密切监控厨房烹饪活动。",
    "验证 Matter 协议下的传感器固件版本，排除软件 Bug 导致的数据溢出。"

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
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。

```json

  "threat_description": "厨房烟雾报警器检测到一氧化碳浓度持续上升，存在潜在的一氧化碳中毒或燃气泄漏风险。",
  "reasoning": [
    "1. 识别关键异常数据：日志显示 kitchen_smoke_alarm (CarbonMonoxideConcentrationMeasurement.MeasuredValue) 在 21:00 至 21:40 期间读数分别为 35, 48, 59。虽然不同厂商对 ppm 单位的缩放因子可能不同（Matter 标准中通常为 0.1ppm 或 1ppm），但数值呈现明显的单调递增趋势，且幅度较大。",
    "2. 排除正常干扰：同一时间段内，厨房温度传感器读数稳定在 2242-2271 之间（约 22.4-22.7°C），没有剧烈波动，排除了因高温导致的传感器误报或火灾初期的热效应。同时，洗碗机在 19:52 启动，虽已运行一段时间，但通常不会导致如此显著且持续上升的一氧化碳读数，除非设备严重故障或通风极差。",
    "3. 结合环境背景：21:00-22:00 是典型的晚餐后时段，入户门传感器和玄关运动传感器频繁触发（20:01, 20:26, 20:56, 21:26, 21:56），表明有人在家活动。如果是一氧化碳泄漏，这属于高危安全事件，必须优先处理。即使读数单位是某种内部标度，这种线性增长模式也强烈暗示了污染源的存在或传感器的漂移/故障，但在未确认校准前，应视为真实威胁。"
