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",

## 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": [

    "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": "high",
  "threat_type": "child_safety",
  "threat_description": "检测到儿童房在无人状态下出现异常高温，随后有人员进入并开启阳台灯，存在儿童独自留在室内或环境失控的风险。",
  "reasoning": [
    "推理步骤 1: 分析温度数据发现，从 14:30 到 15:20，儿童房 (kids_room) 温度传感器读数持续下降（从 24.66°C 降至 24.20°C），而客厅、主卧等其他房间温度也同步下降，这表明空调可能正在运行或室外气温较低，整体环境温度处于正常调节范围。",
    "推理步骤 2: 关键异常点出现在 16:10，此时儿童房运动传感器突然报告 Occupancy = 1（有人），但紧接着在 16:30 和 17:30 多次报告 Occupancy = 0（无人）。更严重的是，在 16:14 分，阳台门接触传感器状态变为 False（打开），且 16:15 分阳台灯被点亮。",
    "推理步骤 3: 结合时间线推断：16:10 有人进入儿童房，随后该人离开（16:30 显示无人），但在离开前并未关闭阳台门（16:14 开门）也未关闭阳台灯（16:15 开灯）。考虑到这是重点关注的儿童房，这种‘进屋 - 开门 - 开灯 - 离开’的模式，若发生在非家长时段或家长不在场时，极有可能是儿童独自活动后误操作，或者有人非法进入后迅速撤离，留下了安全隐患（如窗户/门未关好导致儿童滞留风险或入侵者尾随）。特别是考虑到儿童房通常由家长监管，这种异常的进出和门窗状态变化触发了儿童安全警报。",
    "关键证据": [
      "2026-07-11T16:10:00 儿童房运动传感器检测到有人 (Occupancy=1)。",
      "2026-07-11T16:14:00 阳台门接触传感器状态变为 False (打开)，且 16:15:00 阳台灯被点亮。",
      "2026-07-11T16:30:00 及之后儿童房再次显示无人 (Occupancy=0)，但阳台门仍处于开启状态且灯光亮起，表明离开时未恢复安全状态。"
    ],
    "recommended_actions": [
      "立即检查儿童房及阳台区域，确认是否有儿童被困或遗留物品，确保门窗已正确关闭。",
      "联系住户核实 16:10-16:30 期间的人员活动情况，确认是否为儿童独自活动或外部入侵。",
      "建议检查儿童房智能门锁和阳台门的联动设置，确保当检测到儿童房有人且阳台门打开时能自动报警或通知监护人。"

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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "儿童反复尝试打开受限区域",
  "reasoning": [
    "推理步骤1: 同一门锁短时间连续操作失败",
    "推理步骤2: 来源为按键输入",
    "推理步骤3: 符合儿童尝试受限区域的风险模式"
  ],
  "key_evidence": [
    "同一门锁短时间连续操作失败",

    "判为儿童高风险尝试开门，建议加强门锁与看护。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在连续多次按键尝试失败后，最终成功解锁并开门，且伴随室内灯光和空调自动开启，疑似遭遇暴力破解或密码试错攻击。",
  "reasoning": [
    "推理步骤 1: 在 18:05:00 至 18:07:00 期间，front_door_lock 记录了两次 'LockOperationError(source=Keypad)' 事件，表明用户（或入侵者）正在尝试使用键盘输入密码但连续失败。",
    "推理步骤 2: 紧接着在 18:07:00，系统报告了一次成功的 'LockOperation(LockOperationType=1)'（通常代表 Unlock），随后 DoorLock.LockState 变为 2（Unlocked），证明门锁被打开。",
    "推理步骤 3: 最关键的异常在于时间戳的紧密性：门锁状态改变（18:07:00）仅 2 秒后（18:07:02），前门接触传感器 (front_door_contact) 立即变为 False（门已开）。更可疑的是，几乎同时（18:07:03-18:07:08），客厅的 occupancy、light 和 air_conditioner 全部自动激活。这种‘试错 - 解锁 - 进门 - 全屋联动’的极速序列不符合正常住户回家后的行为模式（通常会有开门动作间隔，且不会瞬间触发所有设备），强烈暗示有人通过快速试错密码进入家中，或者门锁存在严重的逻辑漏洞/被劫持。",
    "关键证据": [
      "18:05:00 和 18:06:00 出现连续的 Keypad 操作错误。",
      "18:07:00 门锁状态迅速从锁定变为解锁 (LockState=2)。",
      "18:07:02 门接触传感器立即检测到门打开 (False)，且随后全屋灯光和空调瞬间启动，缺乏正常的过渡延迟。"
    ],
    "recommended_actions": [
      "立即强制重置入户门锁密码，并检查是否支持远程固件更新以修复潜在的键盘暴力破解漏洞。",
      "通知住户确认是否有人非法闯入，若未授权进入请立即报警。",
      "审查智能家居系统的自动化规则，确保门锁解锁不应无条件直接触发全屋高能耗设备（如空调）的全功率运行，以防被利用作为入侵信号。"

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: ..."
  ],
  "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": "儿童活动从儿童房转移到阳台",
  "reasoning": [
    "推理步骤1: 儿童房活动后很快打开阳台门",
    "推理步骤2: 阳台灯被打开",
    "推理步骤3: 缺少明确陪同信号"
  ],
  "key_evidence": [
    "儿童房活动后很快打开阳台门",
    "阳台灯被打开",
    "缺少明确陪同信号"
  ],
  "recommended_actions": [
    "判定为儿童接近高处风险区域，建议立即干预。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：在儿童房无人且门窗关闭的情况下，阳台门被打开并开启灯光，随后儿童房内出现人员活动迹象。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-08-01T16:10:00 时，儿童房 (kids_room) 的运动传感器报告有人 (Occupancy=1)，但仅持续了约 4 分钟，随后在 16:14:00 变为无人状态。",
    "推理步骤 2: 关键异常发生在 16:14:00，此时阳台门接触传感器 (balcony_door_contact) 状态变为 False（表示门被打开），紧接着在 16:15:00 阳台灯被点亮。这表明有人进入了阳台区域。",
    "推理步骤 3: 结合上下文，从 16:10 到 16:14 期间，所有主要房间（包括客厅、主卧、次卧）的运动传感器均报告为 0（无人）。这意味着进入阳台的人员并非家庭成员正常回家后的路径，而是可能通过其他方式（如窗户或后门）潜入，或者是在家中其他成员不知情的情况下进行的非授权访问。考虑到重点监控的是儿童房安全，这种非正常的夜间/傍晚时段阳台开启及随后的短暂室内活动高度可疑。",
    "推理步骤 4: 温度数据虽然存在波动，但在 Matter 协议中通常以毫开尔文 (mK) 为单位，数值在 2300-2400 之间代表 23-24°C，属于正常室温范围，排除了火灾或设备故障导致的温度异常，进一步凸显了运动传感器和门锁状态的逻辑矛盾是核心问题。"

    "2026-08-01T16:10:00 - 16:14:00 期间除儿童房外全屋无人员活动记录"
  ],
  "recommended_actions": [
    "立即通知住户检查房屋安全状况，确认是否有外人闯入。",
    "检查入户门锁、窗户及其他潜在入口的物理状态是否完好。",
    "调取该时间段附近的视频监控录像进行复核。",
    "建议暂时加强夜间或低光照时段的安防系统灵敏度设置。"

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
{

  "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",

## 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。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的家庭晚间活动模式，无安全威胁或异常行为。",
  "reasoning": [
    "时间线分析：日志记录了从清晨到深夜的正常生活轨迹。早晨 (07:00) 厨房开启，白天儿童房有人员活动 (08:43-21:55)，傍晚 (18:24) 再次使用厨房灶具和灯光，符合典型的家庭作息。",
    "离家确认：在晚上 22:25 左右，系统检测到主卧窗帘关闭、前门接触传感器触发 (True)、门锁执行手动上锁操作 (LockOperationType=0)，随后多个房间（客厅、次卧、主卫）的人员占用状态变为 0，表明住户已正常完成离家流程。",
    "夜间监控：虽然儿童房在夜间仍有温度传感器读数波动和偶尔的占用检测（可能是宠物、短暂进出或传感器误报但被后续逻辑修正），但在 23:20 后儿童房占用状态稳定为 0，且厨房设备在 23:25 关闭，未出现长时间无人看管烹饪或门窗异常开启的情况。",
    "数据合理性：所有温度读数（约 22.5°C）均在舒适范围内，无火灾风险迹象；设备状态变化逻辑连贯，未发现传感器卡死或恶意篡改特征。"
  ],
  "key_evidence": [
    "22:25 前门接触传感器触发且门锁成功上锁，伴随其他房间人员离开。",
    "厨房灶具在 23:25 被关闭，且之后无再开启记录。",
    "儿童房在 23:20 后持续显示无人占用状态，直至日志结束。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统运行正常。",
    "建议定期校准儿童房运动传感器，以减少夜间因微小移动导致的误报占用信号。"
