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",
  "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": "日志显示住户（独居老人）在清晨正常起床、进行洗漱和烹饪活动，随后出门并锁门，所有行为模式符合常规生活规律，未发现安全威胁。",
  "reasoning": [
    "1. **作息与活动分析**：从05:37开始，卧室传感器检测到有人（Occupancy=1），随后床头灯亮起，表明住户起床。05:46卫生间有人且灯亮，06:07厨房有人且灶具开启，这是一套完整的“起床-洗漱-做早餐”的正常晨间流程。",
    "2. **设备状态逻辑自洽**：厨房灶具在06:07开启，06:35关闭，持续时间约28分钟，符合准备早餐的时长，且之后有离开厨房的迹象（虽然中间有短暂返回检测，但整体无长时间无人看管风险）。客厅温度随时间缓慢上升（24.2°C -> 25.1°C），符合早晨室外气温升高或室内供暖/阳光照射的自然物理变化，非异常热源。",
    "3. **离家行为确认**：07:05入户门锁执行了手动上锁操作（LockState=2），紧接着门磁传感器显示门关闭（StateValue=False/True序列通常表示关门动作完成后的闭合状态，结合锁状态变化，确认为离家出门）。玄关运动传感器在07:05:08触发，进一步证实有人通过入口离开。",
    "4. **排除误报**：所有传感器读数（如温度值24xx代表24.xx度）均在合理范围内，无烟雾报警或漏水警报。独居老人的活动轨迹连贯，无长时间静止（跌倒风险低）或反常的深夜活动。"
  ],
  "key_evidence": [
    "05:37 bedroom_occupancy = 1 及 bedroom_light = True (起床)",
    "06:07 kitchen_cook_surface = True (开始烹饪)",
    "07:05 front_door_lock LockState = 2 (上锁) 及 front_door_contact 状态变化 (离家)"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持当前监控策略，继续观察后续日期的类似晨间模式以建立更精准的行为基线。"
  ]
}
```

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

  "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。"
  ],

    "正常样本是早起单次开关灯；异常样本在深夜短时反复切换。"

## 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_type": "none",
  "threat_description": "日志显示为独居老人正常的晨间起床、洗漱及短暂外出活动，未发现安全威胁或异常模式。",
  "reasoning": [
    "1. **时间线与行为逻辑分析**：日志时间跨度为 04:40 至 07:05。05:33 卧室灯亮且窗帘开启，符合老年人早起习惯；随后 05:38 卫生间灯亮，06:07 厨房灯亮并启动灶具，表明住户进行了洗漱和早餐准备，行为连贯且符合生活规律。",
    "2. **烹饪安全性评估**：厨房灶具在 06:07 开启，06:25 关闭，持续约 18 分钟。在此期间，厨房运动传感器（Occupancy）在 06:07、06:27 等时间点多次触发为 1，证明有人在厨房内活动，排除了“无人看管烹饪”的风险。",
    "3. **门锁与出入状态分析**：07:04 入户门出现锁状态变化（LockState 2->1，即从锁定变为解锁再锁定，或反之，结合 Event 描述为 Manual 操作）。考虑到 07:04 之前所有房间（包括客厅、卧室、厨房）的运动传感器均显示 Occupancy=0 或无活动迹象，且 07:04 后玄关运动传感器触发，这极可能是住户出门倒垃圾、取快递或短暂外出。由于是独居老人，这种短暂的短时外出属于正常行为，且门锁最终恢复锁定状态，无入侵迹象。",
    "4. **设备状态检查**：温度传感器读数在 23-25°C 之间波动，属于正常室温范围，无火灾高温报警。烟雾报警器无触发记录。漏水传感器无触发记录。"
  ],
  "key_evidence": [
    "05:33 bedroom_light OnOff=True 伴随 bedroom_occupancy=1，确认住户起床。",
    "06:07 kitchen_cook_surface OnOff=True 与后续 kitchen_occupancy=1 同时存在，确认为有人看管的正常烹饪。",
    "07:04 front_door_lock LockState 变化及 entrance_occupancy=1，结合此前全屋静默，判断为正常短时外出。",
    "全程无 smoke_co_alarm 或 water_leak_detector 报警。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有监控策略，若此类短时外出频率增加，可考虑设置‘离家模式’以自动调整安防等级。"
  ]
}
```

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
{
  "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",

    "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。

    "门锁状态验证：入户门传感器（entrance_occupancy）和接触传感器（front_door_contact）与门锁状态（DoorLock.LockState = 2，通常表示锁定）逻辑一致。例如，16:23 和 17:52 记录到门口有人且门锁已锁，随后人员离开时接触传感器变为 False，表明是住户正常进出，而非非法闯入。",
    "环境数据合理性：温度传感器读数（如 2411, 2395 等）虽然数值较大，但考虑到 Matter 协议中温度常以 0.01°C 为单位存储，实际温度约为 24.11°C，处于舒适且安全的室内范围。光照和占用传感器的触发也与人员移动时间吻合，无死机或漂移迹象。",
    "重点房间监控：针对任务指定的 kids_room（儿童房），运动传感器持续检测到有人（Occupancy=1），且窗帘和窗户传感器未报告异常开启，儿童处于受控的安全环境中。"
  ],
  "key_evidence": [

    "温度读数换算后（~24°C）符合正常室温，排除了传感器故障导致的误报。"
  ],
  "recommended_actions": [
    "继续保持当前的智能家居监控策略。",
    "建议定期检查儿童房窗户传感器的电池电量，确保长期可靠性。"

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",

  ],
  "recommended_actions": [

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。

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": "放学后长期只有浴室活动",
  "reasoning": [
    "推理步骤1: 放学后长时间只有浴室相关信号",
    "推理步骤2: 缺少回到儿童房或公共区域的链路",
    "推理步骤3: 存在异常风险"
  ],
  "key_evidence": [
    "放学后长时间只有浴室相关信号",
    "缺少回到儿童房或公共区域的链路",
    "存在异常风险"
  ],
  "recommended_actions": [
    "标记为儿童异常停留风险，建议人工确认安全。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示家庭处于正常的晚间活动状态，无入侵、设备故障或环境安全隐患。",
  "reasoning": [
    "时间线分析：事件发生在 2026-07-16 下午至傍晚（14:33 - 17:58），符合家庭成员下班回家及晚间活动的正常作息规律。",
    "人员流动逻辑：入户门传感器 (entrance_occupancy) 和门锁状态变化与玄关灯、客厅灯的开启顺序一致，表明是家庭成员正常进出，而非强行闯入。",
    "温度数据验证：所有温度传感器读数（如 kitchen_temp_sensor ~23°C, master_bedroom_temp_sensor ~24°C）均在合理范围内，且数值为整数，排除了传感器漂移、卡死或受到高温/火灾威胁的可能性。",
    "儿童房安全确认：虽然任务重点提及 kids_room，但日志中该房间 occupancy 持续为 1（有人），且窗户接触传感器未触发异常开门事件，窗帘状态正常，未发现儿童独自在家或窗户被非法打开的迹象。",
    "设备行为正常：次卫灯光 (second_bathroom_light) 的多次开关可能是家庭成员轮流使用卫生间，属于正常生活场景；空调在傍晚开启也符合降温习惯。"
  ],
  "key_evidence": [
    "入户门锁 (front_door_lock) 在 16:33 和 17:52 正常上锁，配合门口运动传感器检测到的进入行为。",
    "厨房和卧室温度传感器读数稳定在 23-24 摄氏度之间，无异常升高或波动。",
    "儿童房 (kids_room) 在整个时间段内均检测到有人存在 (Occupancy=1)，且无窗户传感器报警。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续保持对儿童房窗户传感器的监控，确保夜间无人时自动关闭。"
  ]
}
