## 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
{
  "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: ...",

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

  "reasoning": [
    "推理步骤 1: 分析日志中的温度数据，发现 living_room_temp_sensor 的 MeasuredValue 在 2026-08-27 至 2026-08-28 期间数值高达 2308 至 2439。根据 Matter 协议标准及常识，TemperatureMeasurement.MeasuredValue 通常以 0.01°C 为单位，因此该数值代表 23.08°C 至 24.39°C，属于正常的夏季室内温度范围。",
    "推理步骤 2: 然而，仔细观察同一时间段内其他房间（如 second_bedroom、master_bedroom、kitchen）的温度传感器读数，其数值也同步呈现类似的'高位'特征（例如 second_bedroom 达到 2405）。如果这是真实的高温天气，所有房间应同时升高，但需结合 occupancy 事件判断。",
    "推理步骤 3: 关键矛盾点在于：在 2026-08-27T02:30:00 和 2026-08-28T02:00:00 等时间点，多个房间的 occupancy 传感器明确报告为 0（无人），且此时段通常为夜间睡眠或离家时间。若真有人活动导致温度变化，应有相应的 occupancy 记录。更关键的证据是，虽然数值看似正常（23-24度），但在某些上下文中，如果系统配置错误将单位误读为整数摄氏度（即认为室内有 2300 多度），则会导致严重的逻辑冲突。",
    "推理步骤 4: 重新审视任务描述中的'异常模式'提示。对比 2026-08-29 的数据，温度读数回落至 2306-2331 区间，且 occupancy 行为符合常规作息。而在前两天的深夜/凌晨时段，温度读数持续维持在较高位（23xx-24xx），且伴随频繁的传感器上报。考虑到这是一个安全分析场景，最可能的解释并非真实的极端高温，而是**传感器校准漂移（Sensor Drift）**或**固件 Bug 导致的数值偏移**。特别是当多个传感器同时出现非线性的数值跳变或长期维持在不合理的‘高位’（相对于历史基线或预期值）时，极大概率是硬件故障或通信干扰导致的读数失真。",
    "推理步骤 5: 进一步确认：如果这些数值真的是 2300+ 摄氏度，那么烟雾报警器（smoke_co_alarm）和漏水传感器早已触发警报并切断电源，日志中不会出现如此平静的状态。因此，排除真实火灾风险，判定为传感器数据异常（Drift/Malfunction），可能导致自动化空调控制失效或误报。"
  ],
  "key_evidence": [
    "living_room_temp_sensor 在无人占用（Occupancy=0）的深夜时段持续报告异常高数值（2308-2439），与正常室温波动规律不符。",
    "多房间温度传感器（living_room, second_bedroom, master_bedroom, kitchen）在同一时间段内出现同步的数值异常，排除了局部热源干扰的可能性，指向系统性传感器故障或漂移。",
    "尽管温度读数极高，但厨房烟雾报警器和家庭整体未触发紧急响应，说明该数值未被系统正确解读为火灾风险，进一步证实是数据层面的漂移而非真实物理现象。"

## 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": [

    "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": "intrusion",
  "threat_description": "阳台门深夜打开且室内无对应活动",
  "reasoning": [
    "推理步骤1: 深夜阳台门突然打开",
    "推理步骤2: 阳台灯随即被点亮",
    "推理步骤3: 随后出现客厅活动"
  ],
  "key_evidence": [
    "深夜阳台门突然打开",
    "阳台灯随即被点亮",
    "随后出现客厅活动"
  ],
  "recommended_actions": [
    "判定为高风险边界入侵，建议立即检查阳台出入口。"
  ]
}

{
  "is_anomaly": true,
  "confidence": "low",
  "threat_type": "fire_risk",
  "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。

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：

```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。

    "时间与环境状态分析：日志显示在 02:31 至 04:10 期间，所有房间（包括客厅、卧室、厨房）的运动传感器均报告为 '0'（无人），表明住户处于深度睡眠或未醒状态。",
    "入侵排除与异常行为识别：虽然 02:31 和 02:32 记录了客厅和卧室的窗户接触传感器变为 False（打开），但在独居老人深夜无人的情况下，窗户突然开启极不寻常，排除了正常通风的可能性，暗示可能存在外部入侵者试图进入或内部设备故障导致窗户误开/强风。",
    "温度异常趋势确认：最关键的是，在无人且窗户开启的状态下，客厅温度传感器读数从 02:35 的 23.54°C 持续攀升，至 04:00 达到 24.07°C（Matter 协议中通常以 0.1°C 为单位，即 240.7°C 或此处数据单位需结合上下文，但相对趋势明确为急剧上升）。考虑到夜间环境温度通常下降，这种在无热源（空调未运行迹象，且温度高于室温常态）情况下的持续升温是典型的火灾前兆或电气短路过热特征。",
    "综合风险评估：‘无人 + 开窗 + 持续升温’的组合模式强烈指向火情风险。如果是入侵者，他们可能正在使用明火或产生热量的工具；如果是设备故障，可能是电器过热起火。无论哪种情况，对于独居老人而言都是最高级别的安全威胁。"

  "key_evidence": [
    "02:00 - 04:10 期间所有房间 occupancy 均为 0（无人）。",

    "living_room_temp_sensor 读数在 90 分钟内从 ~23.5°C 上升至 ~24.1°C（假设单位为 0.1°C 则温差巨大，即使按字面数值看也是相对于环境异常的上升趋势，结合上下文推断为高温预警），且无降温动作。",
    "卧室温度在此期间反而略有波动但未像客厅那样呈现明显的单向高温爬升，进一步凸显客厅作为异常热点的特征。"
  ],
  "recommended_actions": [
    "立即触发全屋烟雾报警器和紧急通知系统，向监护人或紧急联系人发送最高优先级警报。",
    "自动拨打当地消防部门电话进行远程报备（若系统支持）。",

## 任务
以下是过去 3 天的设备活动记录。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",

}
```

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_description": "检测到凌晨时段（03:14-03:30）客厅存在人员活动，且伴随厨房灯光开启，疑似非正常作息时间的入侵或异常行为。",
  "reasoning": [
    "1. 分析时间模式：日志显示在连续三天（8月9日、10日、11日）的凌晨 03:14 左右，客厅运动传感器（living_room_occupancy）均从 0 变为 1，并在约 16 分钟后（03:30）再次变为 0。这种高度规律性的深夜活动虽然可能属于住户习惯，但在安全分析中，凌晨时段的活跃通常被视为高风险窗口。",
    "2. 关联设备状态：在 8月11日凌晨 03:15，即客厅检测到有人后的1分钟，厨房灯（kitchen_light）被开启（OnOff.OnOff = True）。此前两天同一时间段仅有客厅有人，无厨房灯光记录。这一变化增加了行为的复杂性，暗示住户可能在深夜进入厨房区域。",
    "3. 排除其他威胁：温度传感器读数随时间缓慢上升（符合夜间室温自然波动或空调关闭后的回升），无剧烈跳变，排除传感器故障。未检测到门锁异常开启记录（日志中仅包含重点房间和设备的片段，若门锁有异常通常会作为关键证据列出，但此处主要关注点为室内活动与灯光联动）。结合“一室一厅”布局，客厅到厨房动线合理，但深夜开灯活动本身构成了需要关注的异常行为模式。"

    "3. 设置自动化规则：如果确认为非预期行为，可配置当凌晨特定时间段检测到客厅或厨房活动时，立即发送高优先级警报至用户手机。"
