## 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",

    "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。

  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在住户离家时段连续出现多次键盘操作错误，且伴随全屋人员离开迹象，存在被尝试入侵或设备故障导致无法安全锁门的风险。",
  "reasoning": [
    "推理步骤 1: 分析 occupancy 数据发现，从 17:30 开始，包括客厅、餐厅、主卧、次卧及儿童房在内的所有主要房间运动传感器均报告无人 (Occupancy=0)，表明住户已完全离开房屋。",
    "推理步骤 2: 在确认屋内无人的情况下，日志显示 front_door_lock 在 18:05 至 18:07 期间连续三次报告 'LockOperationError(source=Keypad)'。这种在短时间内针对同一输入源（键盘）的重复失败通常意味着有人正在尝试通过密码进入，或者用户因忘记密码/设备故障而反复尝试。",
    "推理步骤 3: 结合时间线，此时为傍晚 18:00 左右，通常是住户下班回家的高峰期。如果是正常行为，用户应能成功解锁；连续的报错更倾向于外部攻击者尝试猜测密码，或是门锁硬件/固件故障导致无法正常响应合法指令，构成了潜在的安全威胁。"
  ],
  "key_evidence": [
    "17:30 - 19:40 期间，kids_room_occupancy, living_room_occupancy, master_bedroom_occupancy 等多个关键区域持续报告 Occupancy = 0。",

## 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",

  ],

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。

  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 21:20 至 23:20 期间持续报告温度值在 2247 到 2261 之间。",
    "推理步骤 2: 对比同一时间点的其他房间温度传感器（如 living_room 约 2242-2261，master_bedroom 约 2248-2264），虽然数值量级看似接近，但考虑到 Matter 协议中温度通常以 0.1°C 为单位，这些整数数值（如 2247）极有可能是 22.47°C 的误读或者是传感器固件将单位错误地映射为毫开尔文/分度值导致的巨大偏差，或者更可能是传感器完全损坏导致输出固定高位噪声。然而，结合上下文，最合理的解释是传感器读数逻辑错误（例如将 22.47 显示为 2247），因为如果是真实 2247°C，房屋早已烧毁且烟雾报警器会触发。另一种可能性是传感器校准严重失效。",
    "推理步骤 3: 尽管存在这种数值异常，但需确认是否构成直接安全威胁。日志显示该时段内 kids_room_occupancy 为 1（有人），且没有触发 smoke_co_alarm 或 water_leak_detector。如果这是真实的超高温，必然伴随火灾风险；如果是数据格式错误，则属于设备故障。鉴于没有火灾报警联动，且其他房间温度相对平稳，判定为 sensor_malfunction（传感器故障/数据漂移）而非 fire_risk。",
    "推理步骤 4: 综合判断，该异常数据点不符合物理规律（除非发生极端灾难性事件但未触发其他警报），因此归类为传感器本身的 malfunction 或 drift，需要人工干预验证。"

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。

  "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，阳台门被打开并伴随灯光开启，随后出现多人在户内活动的迹象。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-08-27T16:14:00 时，儿童房 (kids_room) 的运动传感器报告有人 (Occupancy=1)，但随后的温度读数波动较大且未持续上升，结合上下文推断此时可能为短暂停留或设备误报，但关键在于紧接着的状态变化。更关键的异常发生在 16:14:00 之后。",
    "推理步骤 2: 在 2026-08-27T16:14:00，阳台门接触传感器 (balcony_door_contact) 状态变为 False（表示门被打开）。此时日志中并未显示入户门 (entrance) 或儿童房窗户被打开的记录，且之前儿童房处于占用状态，若为正常家庭成员活动，通常会有明确的开门路径逻辑。",
    "推理步骤 3: 最可疑的证据是紧随其后的行为模式：在阳台门打开后仅 1 分钟 (16:15:00)，阳台灯 (balcony_light) 被打开。更重要的是，从 15:20 到 16:15 期间，系统记录了多个房间（客厅、主卧、餐厅、厨房）的 occupancy 为 1，但在 16:14 阳台门打开这一关键节点，缺乏对应的“进入”动作记录（如玄关运动传感器先于阳台门动作），且儿童房在 16:14 仍有 occupancy 信号却无后续离开记录，暗示可能存在非授权人员通过阳台进入并在室内移动，或者发生了尾随/非法闯入事件导致室内人员分布异常。考虑到这是安全分析任务，这种‘静默开门 + 开灯 + 多点同时有人’的模式高度符合入侵特征。",
    "修正推理步骤 3 (基于更严谨的逻辑): 重新审视数据，16:14 阳台门打开，16:15 阳台灯亮起。虽然不能直接证明是坏人，但在家庭安防场景下，非工作时间段（下午 4 点多，虽非深夜但需警惕）阳台门突然打开且没有关联的入户门操作记录，属于高风险事件。特别是如果住户习惯是关着阳台门的，此行为即为异常。此外，儿童房在 16:14 仍显示有人，而阳台门开了，这可能意味着有人从阳台进入并进入了儿童房区域，或者入侵者正在屋内活动。综合来看，这构成了潜在的入侵威胁。"

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。

{

  "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"
  ],

  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：在儿童房无人且温度异常的情况下，阳台门被打开并开启灯光，随后入户门锁被手动上锁。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-08-04T14:30 至 16:14 期间，儿童房 (kids_room) 的温度传感器持续报告数值（约 2400-2450），这明显是摄氏度的十分之一单位（即 24.0°C - 24.5°C），表明室内有人活动或环境稳定。然而，关键转折点出现在 16:14，此时儿童房运动传感器仍显示有人 (Occupancy=1)，但紧接着在 16:14:00 阳台门接触传感器状态变为 False (False 通常代表门未关闭/打开)。",
    "推理步骤 2: 更关键的异常在于逻辑顺序。通常在家庭场景中，如果有人在屋内，开门会触发警报或导致人员移动。但在 16:14:00 阳台门打开后，系统并未立即记录到儿童房内的人员离开（直到 16:14:00 之后不久才再次确认 occupancy=1，但这可能是误报或延迟）。更重要的是，在 16:25:00，入户门锁被手动上锁 (LockOperationType=1, LockState=2)。",
    "推理步骤 3: 结合上下文，从 15:30 开始，客厅、次卧等区域 occupancy 变为 0，而主卧和餐厅偶尔有活动，暗示主要家庭成员可能已外出或处于休息状态。此时，阳台门被打开，紧接着入户门被上锁。这种‘先开外门，再锁内门’的行为模式，极有可能是外部人员试图进入家中，或者内部人员试图将某人困在屋内（考虑到儿童房一直有人，存在儿童安全或绑架风险）。特别是如果这是非家庭成员操作，则构成严重的入侵威胁。",
    "推理步骤 4: 虽然日志中显示 16:14 时儿童房 occupancy 为 1，但如果入侵者是从阳台进入，他们可能会先打开阳台门，然后潜入室内。入户门的锁定动作发生在 16:25，距离阳台门打开仅 11 分钟，且在此期间没有其他明显的家庭成员活动记录（如玄关灯频繁开关或大量人员进出），这使得该行为显得非常可疑。"
  ],
  "key_evidence": [
    "2026-08-04T16:14:00 阳台门接触传感器状态变为 False (门打开)，而此时儿童房仍有 occupancy 信号。",
    "2026-08-04T16:25:00 入户门锁执行了手动上锁操作 (LockOperationType=1, OperationSource=Manual)，且此前无明显的家庭成员集体离开的迹象。",
    "事件发生时间段内，其他房间（除主卧和餐厅偶发外）多显示无人状态，增加了单人异常操作的可能性。"
  ],
  "recommended_actions": [
    "立即通知住户核实当前家中人员情况及门锁状态。",
    "检查监控录像（如有）以确认 16:14-16:25 期间是否有陌生人进入或异常移动。",

## 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",

  ],
  "recommended_actions": [

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。

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",
