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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "家长睡后儿童使用厨房电器",
  "reasoning": [
    "推理步骤1: 深夜厨房灯和灶具被打开",
    "推理步骤2: 儿童房活动状态变化",
    "推理步骤3: 缺乏成人陪同上下文"
  ],
  "key_evidence": [
    "深夜厨房灯和灶具被打开",
    "儿童房活动状态变化",
    "缺乏成人陪同上下文"
  ],
  "recommended_actions": [
    "按儿童厨房危险行为处理，建议立即干预。"
  ]
}

{
  "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": [
    "推理步骤1: 日志里有异常，但我把它归因为另一类威胁。"
  ],
  "key_evidence": [
    "深夜厨房灯和灶具被打开"
  ],
  "recommended_actions": [
    "建议按该错误类别处理。"
  ]

## 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
{

  "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": "检测到儿童房在夜间（21:20-23:20）存在人员活动，且室内温度异常升高至约 47°C (2256/10)，疑似有人长时间滞留或设备故障导致过热风险。",
  "reasoning": [
    "时间逻辑分析：日志显示 kids_room_occupancy 在 21:20 后持续为 1（有人），直到 23:20 才变为 0。此时段通常为家庭休息或儿童睡眠时间，非正常活动时间窗。",
    "数据单位推断：厨房灶具和温度传感器读数通常在 0-100 之间。kids_room_temp_sensor 读数在 2242-2266 之间波动，若单位为摄氏度则远超物理极限，极大概率为'分度值 x 10'格式，即实际温度为 22.4°C - 22.6°C。虽然温度本身看似正常，但需结合其他因素判断。",
    "行为模式异常：尽管温度读数经换算后看似正常（~22.5°C），但考虑到这是深夜时段，儿童房出现持续近 2 小时的人员活动（21:20-23:20），而主卧、次卧等其他房间在同一时间段也有频繁的人员进出记录（如 22:21, 22:43, 23:03 等），这表明家庭成员可能并未入睡，或者儿童房并非无人看管状态。然而，更关键的异常在于**温度读数的原始数值特征**。如果系统配置错误导致温度未除以 10，那么 2256 代表 225.6°C，这将立即触发火灾报警。即使假设单位正确，深夜儿童房内持续有人活动也属于需要关注的行为异常（可能是家长陪睡过晚，也可能是儿童独自玩耍）。",
    "综合评估：最显著的风险点在于温度数据的潜在解读歧义。如果该传感器确实报告了 225°C+，则是严重的火灾隐患。如果单位是 0.1°C，则 22.5°C 是正常的室温，但深夜儿童房持续有人活动仍需确认是否涉及儿童安全监护问题。鉴于任务要求识别威胁，且温度数值极其特殊，必须将其视为潜在的传感器漂移或配置错误导致的误报风险，或者是真实的极端高温事件（如果是真实值）。为了安全起见，将其标记为 child_safety（关注儿童房夜间活动及环境安全）。",
    "修正推理：重新审视温度数据。Matter 协议中 TemperatureMeasurement.MeasuredValue 通常以 0.1 为单位。2256 = 225.6°C。这在物理上是不可能的（除非是熔炉）。这强烈暗示**传感器故障（sensor_malfunction）**或**数据上报错误**。然而，题目选项中有 `child_safety`。如果这是一个陷阱题，即温度其实是正常的（比如用户自定义了单位，或者这是某种特定场景），那么重点就是“深夜儿童房有人”。但最合理的解释是：**传感器读数异常（225.6°C）导致了虚假的高温警报风险，或者设备本身已损坏**。不过，观察上下文，其他房间温度也在 2200-2260 范围（22.0-22.6°C）。这说明所有温度传感器都采用了相同的"乘以 10"的缩放因子，或者这就是系统的标准单位。如果这是标准单位，那么 22.5°C 是完全正常的室温。那么唯一的异常就是**深夜儿童房持续有人**。这可能是家长熬夜照顾生病的孩子，也可能是孩子没睡。结合 `kids_room` 的重点监控属性，深夜持续占用可能意味着儿童未按时就寝或处于无人监管状态（如果父母不在场）。",
    "最终判定：虽然温度经换算后正常，但深夜（21:20-23:20）儿童房持续有人活动，且伴随厨房灯光和灶具的零星操作（23:24 开启灯和灶具，虽然后面没关，但这可能是误触或准备做饭），这种非典型的夜间活动模式构成了 `child_safety` 风险（儿童可能未安睡或处于不安全状态）。此外，23:24 厨房灯和灶具突然开启也是一个需要注意的行为点。"

    "2026-07-03T21:20:00 至 23:20:00 期间，kids_room_occupancy 持续为 1，表明儿童房在深夜有持续人员活动。",
    "同一时间段内，其他卧室（master_bedroom, second_bedroom） occupancy 多次切换，显示家庭成员分布复杂，增加了儿童房活动的不确定性。",

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
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：

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",

  ],
  "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。

    "2. 门锁与门禁逻辑一致：15:55 入户门（front_door_lock）执行了手动上锁操作（LockState=2），且紧接着入户门传感器（front_door_contact）状态变为 False（关闭/锁定）。这一序列符合住户回家并反锁门的正常行为，未发现强行破门或非法解锁记录。",
    "3. 温度数据属于正常波动：日志中温度传感器数值（如 2456, 2400 等）对应摄氏度约为 24.5°C - 24.0°C，这是典型的室内舒适温度范围。数值随时间有微小波动（如从 24.56 降至 23.82），符合空调运行或自然散热的环境变化，不存在传感器故障导致的极端跳变或停滞。",
    "4. 无危险设备触发：厨房烟雾报警器、漏水传感器、一氧化碳探测器均无报警事件记录；灶具（cook_surface）虽在设备列表中，但日志未显示其被意外开启或长时间无人看管的状态。"
  ],
  "key_evidence": [
    "15:55:00 front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual) 及后续 DoorLock.LockState = 2，表明是用户主动上锁。",
    "全天多个时间段 kids_room_occupancy 和 living_room_occupancy 交替出现 1 和 0，符合正常居家作息。",
    "所有 temperature_sensor 读数维持在 23.8°C - 24.6°C 之间，无异常高温或低温报警。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",

    "推理步骤 2: 结合常识判断，家庭室内环境温度不可能达到 2400°C 以上，该数值极有可能是传感器硬件故障、校准失效或通信协议解析错误导致的乱码/溢出。",
    "推理步骤 3: 尽管同一时间段内其他房间（客厅、主卧、厨房）的温度传感器读数正常（约 2380-2430），且 occupancy 传感器显示有人存在，这进一步排除了环境极端变化的可能性，确认为单一设备的数据异常。"

## 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: 正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "key_evidence": [
    "正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器读数异常（2300-2400），远超正常物理范围，表明传感器故障或数据上报错误。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 16:10 至 17:40 期间持续报告温度值在 2361 到 2389 之间。",
    "推理步骤 2: 对比同一时间段内其他房间的温度传感器数据（如 master_bedroom 约 2350-2360，kitchen 约 2350-2340），这些数值符合夏季室内常温逻辑（单位应为 0.1°C，即 23.6°C）。",
    "推理步骤 3: 儿童房温度传感器的读数比实际环境温度高出约 230-240 个单位（即 23-24 度），且数值极其稳定，不符合真实环境热力学变化规律，极大概率是传感器硬件故障、校准错误或固件 Bug 导致的数据漂移/卡死。",
    "推理步骤 4: 虽然该异常本身不直接构成入侵或火灾威胁，但作为关键安全设备（尤其是涉及儿童房间），其失效会导致家庭自动化系统无法正确判断室温，可能引发空调误判或延误对真实过热情况的响应，属于设备可靠性风险。"

    "kids_room_temp_sensor 报告值：2389 (16:10), 2390 (16:20), 2372 (16:30) ... 2361 (17:00)。",
    "同期 master_bedroom_temp_sensor 报告值：2362 (17:05)，显示真实环境温度约为 23.6°C，与儿童房异常读数形成巨大反差。"
  ],
  "recommended_actions": [
    "立即检查并重置儿童房温度传感器，确认是否因电池电量低或连接问题导致。",
    "若重置无效，联系设备制造商进行固件更新或申请更换硬件。",
    "在修复前，建议家长手动监测儿童房实际温度，避免依赖自动温控系统。",
    "检查 Matter 网关日志，确认是否存在数据包解析错误或网络干扰导致的数值畸变。"
