## 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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的家庭日常活动及环境监控数据。",
  "reasoning": [
    "1. 人员活动模式分析：日志中多个房间（儿童房、主卧、餐厅、玄关）的运动传感器在下午时段（15:00-16:00+）频繁触发，且呈现多房间同时或交替活跃的状态。这符合家庭成员（如父母和孩子）在下午在家活动的正常行为模式，而非入侵者的单一轨迹。",
    "2. 门锁与门禁状态：16:09 入户门被手动解锁并打开（LockState=2, Contact=False），随后儿童房灯光开启。结合此时段其他房间有人活动的情况，这极有可能是家长回家或孩子在屋内移动导致的正常开门/开灯行为，未发现异常闯入迹象。",
    "3. 温度数据解读：日志中的温度读数（如 2477, 2463 等）数值较高，但观察其变化趋势（从 2477 缓慢降至 2381），变化幅度平缓且连续，符合室内环境温度随时间自然波动的特征（Matter协议中TemperatureMeasurement通常以0.01°C为单位，即24.77°C左右）。无剧烈跳变表明传感器工作正常，无漂移或故障。",
    "4. 关键设备状态：阳台门传感器在16:12显示关闭状态（False），与入户门开启无直接冲突（可能是不同时间段或不同人员操作）。未检测到烟雾、漏水或一氧化碳报警信号。"
  ],
  "key_evidence": [
    "16:09 front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual) - 手动开锁，伴随人员活动",
    "16:11 kids_room_light | OnOff.OnOff = True - 儿童房开灯，与人员存在一致",
    "15:10-16:15 多房间 occupancy_sensor 持续触发 - 符合家庭日常活动规律",
    "kids_room_temp_sensor 数值呈线性缓慢下降 - 传感器工作正常，无故障"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议继续监控夜间（22:00后）的异常活动，以确保睡眠期间的安全性。"
  ]
}
```

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "child_safety",
  "threat_description": "检测到儿童房在无人看管（客厅、主卧等成人活动区域无人员）的情况下，出现长时间且高频的异常高温读数，疑似设备故障或环境失控风险。",
  "reasoning": [
    "时间线分析：从 14:10 到 16:15，儿童房温度传感器持续报告数值在 2390-2477 之间。若单位为摄氏度，该温度远超物理极限；若单位为毫开尔文 (mK)，则换算后约为 2.4°C，与随后其他房间报告的 24°C 左右室温严重不符，表明传感器数据存在严重漂移或故障。",
    "行为模式矛盾：日志显示 14:30、15:00、15:30、16:00 等多个时间点，客厅 (living_room)、主卧 (master_bedroom) 及厨房的温度传感器均正常报告约 24°C 左右的室温，且这些区域有人员活动记录（如 15:11 餐厅有人，15:13 主卧有人）。唯独儿童房温度异常，而儿童房运动传感器在此期间多次报告有人 (Occupancy=1)。",
    "风险评估：虽然运动传感器显示有人，但结合其他房间正常的室温数据和入户/阳台门锁的操作记录（16:09 锁门），推测可能是家长误入或短暂停留。然而，如果温度传感器确实故障导致读数错误，可能掩盖真实的过热风险（如空调故障或外部热源）；反之，如果读数真实（单位错误），则意味着室内环境极度危险。无论哪种情况，单一传感器的异常数据在家庭安全系统中属于高危信号，需立即核实。",
    "排除入侵：尽管有温度异常，但入户门和阳台门的状态变化（16:09 锁门，16:12 阳台门接触状态变化）与内部人员活动时间吻合，未发现明显的非法入侵迹象（如夜间闯入或门窗异常开启时屋内无人）。因此主要威胁指向设备故障导致的潜在安全隐患或儿童安全监测失效。"
  ],
  "key_evidence": [
    "kids_room_temp_sensor 在 14:10-16:15 期间持续报告 2400+ 的数值，而其他所有房间同期报告约 2400 的数值（代表 24°C），单位逻辑冲突明显。",
    "在 kids_room_temp_sensor 异常期间，living_room_occupancy 和 master_bedroom_occupancy 多次报告为 0，且 living_room_occupancy 在 14:30、15:00、15:30、16:00 均为 0，表明成人在场可能性低，增加了儿童独自面对异常环境的担忧。",
    "front_door_lock 在 16:09 被手动上锁，随后 balcony_door_contact 在 16:12 变为 False（开门），此时 kids_room_light 被打开，显示系统处于受控的家庭日常操作模式，而非紧急入侵响应模式。"
  ],
  "recommended_actions": [
    "立即检查儿童房温度传感器硬件连接及供电，确认是否损坏或电池耗尽。",
    "人工进入儿童房核实实际环境温度，检查是否有空调故障、窗户未关导致暴晒或其他热源。",
    "校准或重置儿童房温度传感器，并对比其他房间传感器数据以验证 Matter 协议下的数据一致性。",
    "检查儿童房运动传感器配置，确保其能正确区分人员类型（如成人 vs 儿童），以便在异常高温下触发更高级别的警报。"

## 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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",

  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在尝试通过键盘解锁时发生错误，随后状态异常变为未锁定（State=2），且门传感器随即显示门已打开，存在极高的非法入侵或意外开门风险。",
  "reasoning": [
    "推理步骤 1: 在 2026-07-06T18:05:00 记录到 front_door_lock 出现 'LockOperationError(source=Keypad)' 事件，表明用户尝试使用键盘输入密码进行解锁操作失败。",
    "推理步骤 2: 紧接着在 18:06:00，门锁状态报告为 DoorLock.LockState = 2。根据 Matter 协议标准及上下文逻辑，此状态通常代表 'Unlocked'（未锁定）或故障导致的非安全状态，而非正常的 'Locked'（已锁定）。",
    "推理步骤 3: 在 18:06:02，front_door_contact 传感器立即报告 BooleanState.StateValue = False（即门处于开启状态）。结合之前的锁具报错和随后的开门动作，这表明要么是因为锁具故障导致无法上锁从而被外力推开，要么是有人利用锁具故障成功进入了房屋，构成了严重的安全威胁。"

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",
  "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的家庭日常活动及环境监控数据。",
  "reasoning": [
    "1. 人员活动模式分析：日志显示家庭成员在下午时段（15:13-16:15）在多个房间（主卧、儿童房、餐厅、玄关、客厅）有规律地出现和离开，符合正常居家或短暂离家的行为特征。特别是16:08的入户门手动上锁操作，表明有人在家并进行了安防设置，排除了入侵可能。",
    "2. 传感器状态检查：重点关注的儿童房运动传感器（kids_room_occupancy）在14:10至16:15期间持续报告占用状态（Occupancy=1），且中间有短暂的波动后恢复，这通常意味着有人在房间内活动或停留，并非传感器卡死（Stuck）。温度传感器读数在23.8°C-24.7°C之间波动，属于正常的室内环境温度范围，无异常漂移或故障迹象。",
    "3. 关键设备状态：阳台门传感器（balcony_door_contact）在16:12报告关闭状态（False），与入户门上锁的时间点接近，暗示家庭成员可能在整理家务或准备休息，逻辑连贯。未发现烟雾报警、漏水检测或一氧化碳报警器的触发记录。"
  ],
  "key_evidence": [
    "16:08:00 front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual) - 确认有人在家并执行了上锁动作",
    "14:10:00 - 16:15:00 kids_room_occupancy | OccupancySensing.Occupancy = 1 (间歇性) - 显示儿童房内有人活动，非传感器故障",
    "16:12:00 balcony_door_contact | BooleanState.StateValue = False - 阳台门已关闭，无非法入侵路径"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议继续监控儿童房传感器数据，确保其能准确反映儿童的活动状态，以优化自动化场景（如离家自动关灯/关窗）。"
  ]
}
```

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "child_safety",
  "threat_description": "儿童房在无人看管的情况下出现异常高温，且存在窗户开启与人员活动不一致的潜在入侵或误报风险。",
  "reasoning": [
    "推理步骤 1: 温度传感器数据显示严重异常。从 14:10 到 15:55，kids_room_temp_sensor 报告的温度值在 2384 到 2468 之间（单位通常为 0.1°C），换算后约为 23.8°C 至 24.7°C。虽然数值本身看似正常室温，但结合上下文，这些数值极有可能是传感器故障导致的漂移或读数错误（例如将 24.6°C 误读为 246.8°C 或其他单位混淆，或者传感器完全失效输出高位噪声）。然而，更关键的异常在于：如果这是真实温度，对于有儿童活动的房间，长时间维持在较高温度且无空调调节记录是可疑的；但如果这是传感器故障（sensor_drift/malfunction），则无法准确判断室内真实环境，构成安全隐患。",
    "推理步骤 2:  occupancy 与设备状态逻辑冲突。日志显示 kids_room_occupancy 在多个时间点（如 14:13, 14:53, 15:13 等）检测到有人（Occupancy=1），但在 16:00 之后直到 16:10 才再次确认有人。与此同时，front_door_lock 在 16:08 被手动上锁，随后 balcony_door_contact 在 16:12 变为 False（门开）。这种“入户门锁已关”但“阳台门打开”且“儿童房内持续有人”的状态，需要警惕是否有人通过阳台进入并试图接触儿童，或者仅仅是家庭成员的正常活动。",
    "推理步骤 3: 关键证据指向传感器不可靠。最显著的证据是 kids_room_temp_sensor 在短时间内的剧烈波动（从 2468 降至 2435 再回升），这种非线性的、大幅度的跳变不符合物理热力学规律，强烈暗示传感器发生了漂移（drift）或故障（malfunction）。当负责监测儿童房环境的传感器失效时，系统无法确认是否存在过热危险或火灾前兆，同时也无法准确判断房间内是否真的只有预期的住户，从而构成了 child_safety 风险。"
  ],
  "key_evidence": [
    "kids_room_temp_sensor 在 14:10-15:55 期间报告温度值在 2384-2468 范围内剧烈波动，呈现典型的传感器漂移或故障特征。",
    "在 front_door_lock 于 16:08 上锁后不久，balcony_door_contact 于 16:12 触发开门事件，而 kids_room_occupancy 仍显示有人，需排除非法入侵路径。"
  ],
  "recommended_actions": [
    "立即检查儿童房温度传感器的硬件连接及校准情况，必要时更换传感器以确保环境监测准确。",
    "核实 16:12 阳台门开启时的具体场景，确认是否为家庭成员正常活动，并检查是否有外人通过阳台进入的迹象。",
    "暂时提高对儿童房区域的监控频率，直至传感器数据恢复正常稳定。"

## 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，日志显示为正常的家庭日常活动及环境数据上报。",
  "reasoning": [
    "1. 人员活动模式正常：儿童房（kids_room）在下午时段（14:30-16:20）持续有 occupancy 信号，符合儿童在家活动的特征；客厅（living_room）和主卧（master_bedroom）也有相应的活动记录，且各房间活动存在时间差，符合同居家庭成员在不同区域活动的逻辑。",
    "2. 门锁状态与行为一致：16:20 入户门执行了手动上锁操作（LockOperation=1），随后门磁传感器显示关闭状态（False/Secured）。这一序列是典型的住户回家或离家后的正常安防动作，无非法入侵迹象。",
    "3. 传感器数据合理性：温度传感器读数在 2385-2453 (即 23.85°C - 24.53°C) 之间波动，变化平缓且处于舒适区间，无剧烈跳变，表明传感器工作正常，无漂移或故障。",
    "4. 无异常设备联动或缺失：虽然重点关注的阳台门传感器在 16:12 触发，但结合上下文无其他紧急事件（如烟雾报警、漏水报警），且该时间点前后无异常的门窗开启伴随长时间无人情况，故判定为正常生活场景。"
  ],
  "key_evidence": [
    "16:20:00 front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual) - 手动上锁",
    "16:20:02 front_door_contact | BooleanState.StateValue = False - 门已关好",
    "Kids room occupancy consistently 1 between 14:30 and 16:20 - 儿童房内有人活动",
    "Temperature readings stable around 24°C - 环境温度正常"
  ],
  "recommended_actions": [
    "无需采取任何行动，系统运行正常。",
    "建议继续保持当前的监控策略，关注夜间非正常时段的门窗状态。"
  ]
}
```

{
  "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": [
    "正常样本有客厅成人活动作为陪同上下文；异常样本直达阳台更危险。"
  ],
  "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。

    "推理步骤 1: 分析温度数据发现，从 14:10 到 16:15，kids_room 的温度传感器读数异常偏高（2464-2385），换算为摄氏度约为 24.6°C - 23.9°C。虽然数值本身未达危险高温，但结合后续趋势和上下文需进一步确认单位或相对变化。然而，更关键的异常在于：在 14:30 至 16:15 期间，living_room_occupancy 多次报告为 0（无人），而 kids_room_occupancy 持续为 1（有人）。",
    "推理步骤 2: 观察时间线，15:10 时 master_bedroom_occupancy 变为 1，随后 entrance 和 dining_room 也有人员活动，表明家长或其他成年人在家中其他区域活动。但在 15:30 至 16:10 之间，客厅（主要公共活动区）长时间显示无人（Occupancy=0），而儿童房内一直有人。",
    "推理步骤 3: 关键风险点在于，当主要监护区域（客厅）无人时，儿童房内却持续有人。如果这是午睡时间或孩子玩耍时间，家长在其他房间（如主卧、厨房、餐厅）活动，可能存在监管真空。特别是考虑到儿童房通常有窗帘关闭（虽日志未直接报状态，但结合隐私习惯推测），若孩子独自在内且家长未及时察觉其状态（如哭闹、不适），构成 child_safety 隐患。此外，温度读数若单位为毫开尔文 (mK) 则 2400mK ≈ 24°C 属正常，但若系统逻辑将 mK 误读或实际环境温度因空调故障升高，亦需警惕。综合‘客厅无人’与‘儿童房有人’的时空分离，判定为潜在的儿童安全监控缺失风险。"
