## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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": "洗衣机运行状态正常，倒计时逻辑符合预期，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. 分析洗衣机（balcony_laundry_washer）的状态变化：在 10:00:00 时，OperationalState 变为 1（运行中），随后在 10:20:00 和 10:40:00 分别报告 CountdownTime 为 2400秒（40分钟）和 1200秒（20分钟）。这表明设备正在执行标准的洗涤程序，且剩余时间随时间推移线性减少，符合正常的工作逻辑。",
    "2. 检查任务完成状态：在 11:00:00 时，OperationalState 变为 0（空闲/停止），此时距离开始运行已过去1小时，与之前的倒计时逻辑（从10:20的40分钟推算，至11:00正好结束）完全吻合，说明洗衣程序正常结束。",
    "3. 排除其他异常关联：虽然日志中频繁出现入户门传感器（entrance_occupancy）的触发记录（如 07:34, 08:09, 08:29 等），但这属于住户日常进出行为，且发生在白天工作时间段，结合无门锁异常操作、无烟雾报警、无漏水报警等其他关键安全事件，判定为正常生活场景，不构成安全威胁。"

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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_description": "当前日志更符合正常模式，不建议报警。",

  "threat_description": "客厅温度传感器 (living_room_temp_sensor) 在空调开启后出现严重的数据漂移和逻辑矛盾，导致无法准确反映真实室温。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-08-18T13:00:00 用户手动开启了客厅空调 (living_room_ac OnOff=True)，随后从 13:15:00 开始，温度传感器读数出现剧烈且无规律的波动（如 2840 -> 2720 -> 2486 -> 2610），这与空调制冷应使室温平稳下降的物理规律完全不符。",
    "推理步骤 2: 对比同一时间段内其他房间的温度传感器数据（如厨房、主卧、儿童房），其数值均在 2400-2550 之间缓慢、平滑地变化，符合正常的热力学环境特征，证明系统整体数据采集正常，问题仅局限于客厅温度传感器。",
    "推理步骤 3: 检查后续日志，尽管空调持续运行且室外有人活动，该传感器读数在 13:55:00 再次出现跳变（2473 -> 2610），并在之后长时间维持异常高位或随机跳动，表明传感器硬件故障或固件逻辑错误，已失去作为安全监控依据的有效性。"
  ],
  "key_evidence": [
    "2026-08-18T13:00:00 客厅空调开启事件与随后温度读数的非物理性剧烈波动存在直接因果冲突。",
    "同期其他房间温度传感器数据稳定且趋势合理，排除了全局网络或协议层面的普遍故障。",
    "传感器读数在短时间内多次发生超过 100 单位（约 0.1°C）的无理由跳变，远超正常测量误差范围。"
  ],
  "recommended_actions": [
    "立即标记 living_room_temp_sensor 为‘故障’状态，并在自动化规则中暂时屏蔽该传感器的报警触发功能，防止误报。",
    "安排技术人员上门检修或更换客厅温度传感器硬件，并检查其供电及连接线路。",
    "在维修完成前，建议用户通过手持式独立温度计人工监测客厅实际温度，以评估空调制冷效果及室内舒适度。"

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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

    "2. 门窗状态分析：09:10左右客厅窗帘打开（位置50%）且窗户接触传感器显示关闭（False通常表示闭合/安全，True表示开启/不安全，此处需结合上下文，但随后09:20变为True可能表示窗户被打开通风，这是正常行为）。没有检测到非法入侵特征（如门锁异常操作伴随非住户时间的窗户开启）。",
    "3. 人员活动模式：06:26卧室有人活动并拉开窗帘，07:31门锁手动解锁并关闭（出门），09:10后客厅无人（Occupancy=0），整体动线符合居民早起、洗漱、出门上班/外出的正常生活节奏。",
    "4. 其他设备状态：卫生间灯在06:34亮起，厨房灯在06:51亮起后于07:31熄灭，均与人员活动时间段吻合，无长时间无人常亮等异常情况。"
  ],

    "门锁操作记录显示07:31为Manual解锁后关闭，符合离家场景。",
    "运动传感器显示06:26卧室有人，之后各区域无异常持续占用，符合作息规律。",
    "窗户和窗帘操作发生在白天（09:10），属于正常通风行为。"
  ],
  "recommended_actions": [
    "无需采取任何安全措施。",

    "推理步骤 2: 将客厅温度与同一时间段内的其他房间温度进行对比。bedroom_temp_sensor 和 kitchen_temp_sensor 的读数均在 2380-2540 范围内（即 23.8°C - 25.4°C），符合夏季清晨至上午的正常室温变化规律。",
    "推理步骤 3: 结合住户行为日志，期间有人员活动（卧室有人、开门出门等），且窗户曾被打开（living_room_window_contact 变为 False 后恢复 True），排除了密闭空间内设备发热导致的高温可能性。客厅温度若真达到 250°C+，必然触发烟雾报警或导致房屋结构损坏，但 kitchen_smoke_co_alarm 未报警，证明该读数非真实环境温度，属于典型的传感器漂移（Sensor Drift）或校准错误。"

## 任务
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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": "未检测到安全威胁或设备故障，日志显示为正常的家庭环境监控及洗衣机定时运行状态。",
  "reasoning": [
    "1. 分析重点设备（阳台洗衣机）：日志显示在 10:00 时 OperationalState 变为 1（运行中），随后在 10:20 和 10:40 出现 CountdownTime 递减（2400s -> 1200s），最后在 11:00 变为 0（完成/空闲）。这符合洗衣机设定延时启动或剩余时间计时的正常逻辑，无异常卡死或错误代码。",
    "2. 分析传感器数据一致性：所有温度传感器读数在 2490-2559 (单位通常为 0.01°C，即 24.9°C - 25.6°C) 之间波动，变化平缓且符合夏季室内环境温度特征，无突变、跳变或超出物理范围的数值，排除传感器漂移或故障。",
    "3. 分析人员活动模式：多个房间的运动传感器（OccupancySensing）持续报告 Occupancy = 0，表明房屋内无人。结合洗衣机在无人状态下自动完成工作，推测为预设的定时任务或远程启动，属于正常行为模式，非入侵或异常滞留。"
  ],
  "key_evidence": [
    "balcony_laundry_washer OperationalState 从 1 变为 0，伴随 CountdownTime 正常递减，表明洗衣程序完整执行。",
    "所有 TemperatureMeasurement.MeasuredValue 保持在合理室温区间 (24.9°C - 25.6°C)，无剧烈波动。",
    "多处 occupancy_sensor 持续报告 0，确认房屋处于无人状态，与自动化家电运行场景相符。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议定期检查洗衣机滤网以确保长期运行效率，但当前日志无故障迹象。"
  ]
}
```

{
  "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": [
    "正常样本倒计时递减并停止；异常样本数值长时间固定。"
  ],
  "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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本窗户/窗帘状态变化一致；异常样本存在重复矛盾读数。"
  ],
  "key_evidence": [
    "正常样本窗户/窗帘状态变化一致；异常样本存在重复矛盾读数。"
  ],

  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到客厅和厨房温度持续异常升高，且伴随窗户开启但室内无人，存在严重的火灾风险或设备过热隐患。",
  "reasoning": [
    "推理步骤 1: 分析温度数据趋势。从 03:10 到 11:10，客厅温度传感器读数从 23.65°C (2365/100) 持续上升至 25.41°C (2541/100)，其中在 09:30 达到峰值 25.59°C。虽然绝对值看似不高，但需结合上下文判断。更关键的是，厨房温度在同一时间段内也呈现同步上升趋势，从 24.79°C 升至 25.57°C。",
    "推理步骤 2: 关联 occupancy（占用）状态。日志显示，在温度显著上升的整个时段（03:10 - 11:10），living_room_occupancy 和 kitchen_temp_sensor 附近的区域均报告 Occupancy = 0（无人）。这意味着房间处于无人看管状态，而温度却在持续攀升，这不符合正常自然降温或恒温逻辑，暗示有热源持续工作。",
    "推理步骤 3: 检查安全设备与物理环境。尽管温度升高，但 living_room_window_contact 在 09:10 变为 False（打开），随后在 09:20 又变为 True（关闭）。如果是因为开窗散热导致温度变化，通常会有明显的通风气流特征，且不会在关窗后温度继续维持高位。更重要的是，厨房烟雾报警器 (smoke_co_alarm) 在此期间的日志中完全缺失，而在高温且无人的情况下，若存在电气故障或燃气泄漏引发小火苗，烟雾报警器应已触发报警。这种‘高温 + 无人 + 无烟雾报警’的组合是典型的传感器失效或早期火灾被掩盖的迹象。此外，卧室灯在 06:22 开启，但随后所有房间 occupancy 均为 0，说明住户并未在室内活动，排除了人为开空调取暖的可能性。",
    "推理步骤 4: 综合判断。在无人员活动的情况下，厨房和客厅温度持续非自然上升，且关键的烟雾探测设备未响应，极有可能是厨房灶具 (cook_surface) 或其他电器发生过热、短路等故障，或者烟雾传感器本身发生故障未能检测危险。考虑到 Matter 协议下设备报告的连续性，这种长时间的高温累积是一个高危信号。"
  ],
  "key_evidence": [
    "living_room_temp_sensor 和 kitchen_temp_sensor 在无人 (Occupancy=0) 的情况下持续升温，最高达 25.59°C 和 25.57°C。",
    "在温度异常升高的整个过程中，厨房烟雾报警器 (smoke_co_alarm) 没有任何事件记录，存在安全隐患。",
    "住户行为模式异常：卧室灯开启后，所有房间长期无人，排除了正常生活场景下的温度波动。"
  ],
  "recommended_actions": [
    "立即远程通知住户家中存在高温异常，并建议其尽快回家检查厨房及客厅情况。",
    "强制重置或重新校准厨房烟雾报警器，确认其功能是否正常。",
    "检查厨房灶具及其他大功率电器的运行状态，排查是否存在过热或故障。",
    "若无法联系到住户，建议物业或安保人员上门进行物理检查。"

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本空调开启后温度逐步下降；异常样本持续不降反升。"
  ],
  "key_evidence": [
    "正常样本空调开启后温度逐步下降；异常样本持续不降反升。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"

  "reasoning": [
    "推理步骤 1: 在 2026-08-20T13:00:00，系统检测到客厅空调 (living_room_ac) 被开启 (OnOff.OnOff = True)，此时客厅温度传感器读数约为 25.0°C (2501 mK)，符合常理。",
    "推理步骤 2: 随后在 2026-08-20T13:15:00，即空调开启仅 15 分钟后，温度传感器读数突然飙升至 28.4°C (2840 mK)。考虑到空调正在运行且其他房间温度正常下降或持平，这种瞬间剧烈升温不符合物理规律（除非是极端的局部热源，但无相关日志支持）。",
    "推理步骤 3: 更关键的异常发生在 2026-08-20T13:35:00，当空调已运行一段时间，理论上室内应开始降温时，温度传感器读数再次异常跳变至 27.2°C (2720 mK)，而同一时刻厨房、次卧、主卧的温度均在 24.8°C - 24.9°C 之间稳步下降。这表明传感器数据与其他环境数据严重背离，存在明显的漂移或故障。",
    "推理步骤 4: 尽管后续数据有所回落，但在空调运行期间出现的多次非单调、大幅度的数值波动（如从 24.8 跳到 28.4 再跳回 24.8），强烈暗示传感器硬件故障、校准失效或通信干扰，属于典型的 sensor_malfunction。"
