## 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": [

    "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": "日志显示为正常的晚间家庭活动模式，包括人员回家、开启空调和照明、使用厨房电器及洗碗机，未发现安全威胁或设备异常。",
  "reasoning": [
    "1. **人员活动轨迹正常**：18:02 玄关运动传感器触发，随后 18:12 门锁手动解锁且门磁关闭（关门），表明有人回家。之后客厅、主卧、玄关等区域在 18:12-21:17 期间多次出现运动检测，符合家庭成员在客厅休息、在主卧活动的常态行为。",
    "2. **环境控制逻辑合理**：18:12 回家后不久（18:12:27）开启客厅空调，此时室内温度约 23°C 左右（传感器数值需除以100，即23.56°C->23.12°C），开启空调降温符合夏季傍晚的生活习惯。19:00 开启客厅主灯，符合夜间照明需求。",
    "3. **厨房与家务活动正常**：18:19 灶具开启，19:30 洗碗机启动，表明进行了晚餐烹饪和清洁工作。虽然灶具开启时间较长，但期间有人员在厨房附近活动（通过其他传感器间接推断或虽无直接厨房人感但结合生活常识判断），且未检测到烟雾报警，属于正常的无人值守烹饪场景（如炖煮），非危险状态。",
    "4. **数据解读正确**：温度传感器数值（如 2356）对应 Matter 协议中的厘度（centi-degrees），即 23.56°C，处于舒适室温范围，无过热或传感器故障迹象。"
  ],
  "key_evidence": [
    "18:12 front_door_lock LockOperation(Manual) + front_door_contact False: 确认有人回家并关门。",
    "18:12:27 living_room_ac OnOff=True: 回家后开启空调，逻辑连贯。",
    "19:00:00 living_room_light_1 OnOff=True: 晚间开灯，符合作息。",
    "19:30:05 kitchen_dishwasher OperationalState=1: 饭后清洗餐具，正常家务流程。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有自动化规则，确保灶具长时间开启时若有烟雾报警器联动则能正常响应（当前日志未触发报警，说明安全）。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",

## 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",
  "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
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的傍晚家庭活动模式（烹饪、清洁、休闲）。",
  "reasoning": [
    "1. **烹饪行为分析**：厨房灶具 (kitchen_cook_surface) 在 17:45 开启，于 18:47 关闭，持续约1小时。随后洗碗机 (kitchen_dishwasher) 立即启动。这符合典型的晚餐准备及餐后清理流程，属于正常的人类行为习惯，不存在无人看管的风险。",
    "2. **环境与安全状态**：在烹饪期间，烟雾报警器 (smoke_co_alarm) 未触发任何报警事件；厨房窗户传感器 (kitchen_window_contact) 在 18:47 显示关闭状态（StateValue=False，通常Matter中False表示Closed/Secure），表明门窗处于安全闭合状态，无入侵迹象。",
    "3. **人员活动轨迹**：客厅运动传感器 (living_room_occupancy) 在 16:40-18:40 期间多次报告有人存在，与晚间居家活动时间吻合。卧室和玄关传感器均报告无人（Occupancy=0），符合家庭成员集中在客厅和厨房活动的逻辑。",
    "4. **数据完整性检查**：虽然部分温度传感器在特定时间点返回 `None`（如 17:46, 18:48），但这发生在设备操作（开火、启动洗碗机）或网络波动间隙，且后续读数恢复正常范围（22-23°C左右，注意Matter协议中温度值通常为摄氏度*100，即2300代表23.00°C），未见持续的传感器故障或漂移特征。"
  ],
  "key_evidence": [
    "kitchen_cook_surface OnOff=True (17:45) 后接 Off=False (18:47)，伴随 dishwasher 启动，形成完整的烹饪-清洁闭环。",
    "smoke_co_alarm 全程无报警记录。",
    "living_room_occupancy 在傍晚时段持续为 1，符合居家常态。",
    "temperature_sensor 数值在 2290-2370 (22.9-23.7°C) 之间波动，属正常室温范围。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议定期检查厨房烟雾报警器的电池状态以确保长期可靠性。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "正常样本回家后有客厅/厨房过渡活动；异常样本直接进入卧室。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}


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",

    "1. 温度数据解读：日志中客厅温度传感器读数在2300-2380之间波动（如2360, 2359, 2346等）。根据Matter协议标准，TemperatureMeasurement.MeasuredValue单位为厘氏度（cHundredths of a degree Celsius），即除以100后为摄氏度。因此，实际室温约为23.0°C - 23.8°C，处于舒适范围内，且呈现缓慢下降趋势，符合开启空调后的正常降温逻辑。",
    "2. 设备联动分析：18:08分入户门锁手动上锁（LockState=2），随后18:08:09客厅 occupancy 变为1，紧接着18:08:14客厅主灯亮起，18:08:24客厅空调开启并设置模式为3（通常为Cool/制冷）。这一系列动作构成了典型的‘回家’行为模式：进门、开灯、开启空调降温。",
    "3. 人员活动轨迹合理：从17:30到18:30期间，多个房间（餐厅、主卧、玄关、儿童房）的运动传感器交替触发，表明家庭成员在家中不同区域活动（如准备晚餐、休息、走动等），无长时间静止或异常入侵迹象。",
    "4. 门窗状态正常：入户门在18:08上锁后保持关闭状态（Contact Sensor False表示关闭/锁定，True表示打开，需结合具体实现，但通常LockState=2 Locked意味着门已锁好），且无反复开关的异常记录。厨房灯光在18:24和18:33亮起，符合晚餐准备场景。"

## 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",
  "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",

  "threat_description": "未检测到安全威胁或异常模式，日志显示为正常的晚间家庭活动及环境调节行为。",
  "reasoning": [
    "1. 人员活动轨迹符合正常生活规律：从17:44开始，客厅、主卧、儿童房、餐厅、玄关等区域陆续出现 occupancy（有人）信号，且持续时间合理。例如，19:00-21:30期间客厅灯开启，伴随客厅和餐厅的持续有人信号，符合晚餐及晚间休闲场景。",
    "2. 设备控制逻辑正常：19:00 客厅主灯开启，21:30 关闭，符合夜间照明习惯。19:38 洗碗机启动，通常用于晚餐后清洁，与活动时间线吻合。空调在17:44被设置为制冷模式（SystemMode=3），随后各房间温度传感器读数呈现缓慢下降趋势（如客厅从2359降至2245），表明空调正在有效工作并降低室温，无故障迹象。",
    "3. 无入侵或非法访问迹象：入户门传感器仅在特定时间点有短暂触发（如18:34, 18:54等，虽日志主要记录的是occupancy而非door_lock状态，但结合室内人员活动，未见深夜无人时的异常门锁操作或长时间未关闭的门磁报警）。所有运动传感器数据均在合理时间窗口内波动，无长时间静止后的突然激活（可能暗示跌倒）或完全无活动的静默期（排除健康隐患）。",
    "4. 环境参数稳定：温度读数随空调运行逐渐降低，变化曲线平滑，无剧烈跳变，说明传感器工作正常，无漂移或故障。"
  ],
  "key_evidence": [
    "客厅主灯在19:00开启，21:30关闭，符合晚间作息。",
    "空调于17:44启动制冷，后续多房间温度传感器数值持续下降（如客厅2359->2245），证明设备正常运行。",
    "洗碗机在19:38启动，与晚餐后时间段一致。",
    "各房间运动传感器在傍晚至夜间均有间歇性激活，符合家庭成员在家走动特征，无异常静默或突发异常。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则监控，确保空调节能设置与舒适度平衡。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"

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

  "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",

    "推理步骤 3: 厨房灶具 (cook_surface) 和洗碗机 (dishwasher) 在该时间段内无开启记录，且烟雾报警器未触发，排除了真实火灾风险。因此，厨房温度传感器的极端高值属于典型的传感器漂移或硬件故障，而非真实环境变化。"

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。
