## 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": [

  ],

    "正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数出现严重漂移，数值异常偏高且与卧室温差逻辑不符，可能导致空调控制失效或误报高温。",
  "reasoning": [
    "推理步骤 1: 分析时间序列数据发现，从 09:00 到 17:00，living_room_temp_sensor 的 MeasuredValue 长期维持在 2536-2558 之间（换算为摄氏度约为 25.4°C），而同一时间段内 bedroom_temp_sensor 的读数稳定在 2186-2416 之间（换算为摄氏度约为 21.9°C-24.2°C）。",
    "推理步骤 2: 对于独居老人家庭，夏季白天室内温度通常不会达到 25.4°C 以上（除非极端天气且未开空调），且客厅与卧室存在约 3-4°C 的持续温差不符合常规热力学分布（通常卧室因封闭性保温更好或更差，但如此大的固定温差需结合设备状态判断）。",
    "推理步骤 3: 关键转折点出现在 17:00，此时 living_room_temp_sensor 突然跳变至 2520，随后在 17:30 降至 2350，18:40 降至 2303，19:30 降至 2279。这种先长时间高位悬浮、后随时间自然下降的模式，极大概率是传感器校准错误（Drift）或固件 Bug 导致的读数虚高，而非真实环境温度变化。若按此读数，空调系统可能无法正确启动制冷，导致老人中暑风险。",
    "推理步骤 4: 对比厨房和卧室的温度趋势，厨房温度随 occupancy 活动有波动但整体合理，卧室温度随夜间/傍晚逐渐下降符合规律，唯独客厅传感器行为异常，排除了环境因素干扰。"
  ],
  "key_evidence": [
    "2026-08-01T09:00:00 至 17:00:00 期间，客厅温度读数异常稳定在 ~25.4°C (2540)，远高于卧室同期读数 (~22-24°C)。",
    "2026-08-01T17:00:00 之后，客厅温度读数开始呈现符合物理规律的下降趋势 (2520 -> 2350 -> 2279)，证实之前的读数并非真实环境温度。",
    "独居老人场景下，25.4°C 的持续高温读数若被 HVAC 系统采信，将导致制冷不足，构成健康隐患。"
  ],
  "recommended_actions": [
    "立即检查客厅温度传感器的硬件连接及供电情况，排除接触不良导致的信号异常。",
    "重置客厅温度传感器并重新校准，或将其暂时替换为备用传感器以确保老人居住环境安全。",
    "通知住户或家属关注当前实际室温，必要时手动开启空调降温，防止因传感器误报导致自动温控失效。",
    "在修复前，建议通过其他手段（如手持温度计）人工监测客厅温度，作为临时验证。"

## 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. 识别关键事件：日志显示在 2026-07-01T10:00:00，阳台洗衣机（balcony_laundry_washer）的 OperationalState 变为 1（通常表示运行中），同时未立即出现倒计时，可能为启动瞬间或初始状态上报。",
    "2. 验证工作周期：在 10:20:00，洗衣机上报 CountdownTime = 2400秒（40分钟）；在 10:40:00，CountdownTime 减少至 1200秒（20分钟）。这表明设备正在按标准程序进行洗涤/脱水流程，时间递减逻辑正确，无停滞或异常跳跃。",
    "3. 确认任务完成：在 11:00:00，洗衣机 OperationalState 变为 0（停止/空闲），此时距离 10:20 的 2400秒倒计时结束正好过去 20分钟（即从10:20到11:00共40分钟，与初始设定的2400秒一致）。这证明洗衣任务已完整执行并正常结束。",
    "4. 排除其他风险：在此期间，虽然有多处人员活动（如玄关、餐厅运动传感器触发），但均属于正常的家庭日常活动模式，且没有伴随门锁异常开启、烟雾报警或漏水等并发安全事件。"

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: ...",

    "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": "所有设备状态变化符合正常家庭晚间活动模式，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. 门锁操作分析：日志显示在 18:08 发生了一次手动开锁（LockOperationType=1），随后在 22:43 发生了一次手动闭锁（LockOperationType=0）。这符合住户回家开门、夜间睡觉前关门的标准行为逻辑，且中间间隔合理，无异常频繁尝试或非法入侵迹象。",
    "2.  occupancy 传感器与灯光联动：客厅运动传感器（living_room_occupancy）在 18:18 至 22:18 期间持续报告有人（Value=1），这与客厅主灯在 20:10 开启并在 20:18 调暗的行为一致，表明是住户在客厅活动后调整照明，属于正常的人机交互。",
    "3. 温度数据合理性：各房间温度传感器读数随时间缓慢下降（从约 24.7°C 降至 22.4°C 左右），变化趋势平滑，无突变或停滞，表明传感器工作正常，且空调可能正在制冷或室外温度降低导致室内降温，符合物理规律。",
    "4. 其他设备状态：厨房灶具在 19:04 关闭，洗碗机在 19:53 启动，均为正常的晚间家务活动；卫生间和次卧的无人状态（Occupancy=0）也符合家庭成员集中在客厅和主卧的晚间习惯。"

    "living_room_light_1 | OnOff.OnOff = True at 20:10 followed by LevelControl adjustment, consistent with living_room_occupancy = 1",
    "Temperature sensors show gradual decrease from 24.71 to 22.42 over 8 hours, indicating normal environmental changes."

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",

    "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": "卧室温度传感器 (bedroom_temp_sensor) 存在严重的读数漂移和逻辑矛盾，导致无法准确反映真实环境温度。",
  "reasoning": [
    "推理步骤 1: 数据单位分析。日志中的温度值（如 2167, 2420）远超物理可能的摄氏度范围，结合 Matter 协议常见实现，这些数值极有可能是以 0.01°C 为单位的原始整数（即实际温度为 21.67°C - 24.58°C），属于正常室温波动范围。",
    "推理步骤 2: 异常突变检测。在 2026-08-27T14:00:00 时刻，同一设备在短时间内连续报告了两个截然不同的数值：先报 2383 (23.83°C)，紧接着报 2430 (24.30°C)。虽然温差不大，但随后在 14:10:00 再次出现剧烈跳变，从 2360/2470 瞬间变为 2352，且在同一分钟内有多个冲突读数。",
    "推理步骤 3: 逻辑一致性校验。最关键的异常发生在 2026-08-27T14:00:00 至 14:10:00 期间。数据显示卧室有人 (Occupancy=1)，但温度读数在 23°C 到 24°C 之间剧烈震荡，而与此同时，客厅 (living_room) 的温度却稳定在 24°C 左右并缓慢下降。如果卧室真的发生了如此剧烈的温度变化（例如空调故障或窗户大开），相邻的客厅温度应会有相应反应，或者两个房间温差会显著拉大。然而，卧室温度的这种高频、无规律的锯齿状波动不符合热力学规律，表明传感器本身可能接触不良、校准失效或固件读取错误。",
    "推理步骤 4: 结论。尽管数值经过换算后看似在合理范围内，但其随时间变化的模式（高频抖动、非物理性的瞬时跳变）与周围环境的稳定状态不符，判定为传感器硬件故障或通信干扰导致的 malfunction。"
  ],
  "key_evidence": [
    "2026-08-27T14:00:00 时 bedroom_temp_sensor 在 1 分钟内从 2383 跳变至 2430，随后在 14:10 又出现 2360/2470 的冲突读数。",
    "卧室温度呈现无规律的锯齿状剧烈震荡，而同一时间段内客厅温度保持相对稳定且呈线性下降趋势，两者缺乏应有的热耦合关系。",
    "Matter 协议下 2167-2470 的数值若直接解读为摄氏度则严重超标，若解读为 0.01 单位虽在常温范围，但其波动频率和幅度超出了正常环境噪声水平。"
  ],
  "recommended_actions": [
    "立即检查卧室温度传感器的物理连接和供电情况，排除接触不良。",

## 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。

  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-07-24T13:55:00 至 14:00:00 期间，卧室温度从正常的 2371-2379 (约 23.8°C) 突然剧烈波动至 2430 (约 24.3°C)，紧接着在 14:05:00 瞬间跳变为 2550 (约 25.5°C)，这与同一时间段客厅温度 (约 24.7°C) 和厨房温度 (约 24.7°C) 的稳定趋势完全不符。",
    "推理步骤 2: 自 14:05:00 之后，该传感器读数开始呈现非物理规律的持续下降趋势，从 2470 一路跌至 19:20 的 2278 (约 22.8°C)。考虑到夏季环境（根据日志中其他房间 24-25°C 推断），室内温度不应在没有空调干预的情况下自然大幅下降超过 2°C，这种线性/阶梯式下降不符合热力学规律。",
    "推理步骤 3: 结合 Matter 协议特性，此类短时间内的大幅度数值漂移（Drift）和随后的单向衰减通常不是真实环境温度变化，而是传感器硬件故障、校准丢失或供电不稳导致的测量错误。若为入侵者试图通过制造低温假象干扰系统，通常不会伴随如此剧烈的瞬时跳变。"
