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",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",

}
```

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_description": "厨房温度传感器在烹饪活动期间出现严重数据漂移和逻辑矛盾，导致无法准确监测火灾风险。",
  "reasoning": [
    "推理步骤 1: 日志显示在 19:01 开启厨房灯后，19:28 关闭灶具前，厨房温度传感器读数从正常的 2300-2400 (约 23-24°C) 异常飙升至 2675 (约 26.7°C)，随后在 20:10 再次跳变至 2419，并在 20:20 骤降至 2335。这种剧烈且不符合物理规律的波动（尤其是短时间内超过 200 个单位的变化）表明传感器读数不可靠。",
    "推理步骤 2: 尽管灶具在 19:28 被关闭，但传感器读数并未如预期般稳定或缓慢下降，而是在 19:45 仍显示高达 2636 的数值，直到 20:10 才回落。这与卧室和客厅温度传感器的平稳变化形成鲜明对比，排除了环境温度自然变化的可能性。",
    "推理步骤 3: 结合 Matter 协议标准，TemperatureMeasurement.MeasuredValue 通常以 0.1°C 为单位。数值达到 2600+ 远超正常室温范围，极可能是传感器硬件故障、校准丢失或通信干扰导致的‘传感器漂移’或‘传感器故障’。若该传感器用于联动烟雾报警器或自动切断电源，此故障将直接导致家庭面临真实的火灾隐患。"

## 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：

  "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",

    "1. **夜间至清晨状态正常**：从00:00到06:40，所有主要房间（主卧、客厅、浴室）的运动传感器均显示无人（Occupancy=0），符合深夜睡眠时的行为模式。温度数据呈现缓慢上升的自然趋势，无异常波动。",
    "2. **起床活动逻辑连贯**：06:44浴室有人，随后06:55主卧有人，07:03浴室灯关闭，07:05客厅灯开启。这符合典型的“起床-洗漱-整理”的早晨作息顺序。",
    "3. **离家行为一致**：07:18门锁上锁（LockState=2通常表示已锁定/已启用），紧接着入户门传感器触发（BooleanState.StateValue=True，在Matter中Contact Sensor通常True代表闭合/关闭，False代表打开；此处结合上下文，若门锁已锁且人离开，门应处于关闭状态）。07:28玄关运动传感器被触发，表明住户经过玄关区域。",
    "4. **后续活动合理**：07:48和08:08等时间点玄关再次有运动检测，可能是住户在家中进行其他活动或短暂返回取物，但并未伴随任何入侵迹象（如门锁被非法开启、窗户异常打开等）。整体时间线和设备联动符合人类日常行为逻辑。"

  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 07:18:20 发生关键事件，入户门锁 (front_door_lock) 状态变为 '2' (通常代表 Unlock/已解锁)，紧接着在 07:18:28 入户门接触传感器 (front_door_contact) 状态变为 True (门已打开)。",
    "推理步骤 2: 结合上下文，此时家中所有房间 (living_room, master_bedroom, second_bedroom, bathroom) 的 occupancy 传感器均报告为 0 (无人)，表明屋内无人在场。然而，仅 3 分钟后 (07:28:23)，玄关运动传感器 (entrance_occupancy) 突然检测到有人进入 (Occupancy = 1)。",
    "推理步骤 3: 这种‘全屋无人 -> 门锁瞬间解锁 -> 门开 -> 玄关有人’的序列不符合正常的起床出门模式（通常会有卧室有人、客厅有人等前序动作）。此外，日志中厨房温度持续异常升高至 254°C+ (实际应为 25.4°C，但数值本身极高可能暗示传感器故障或极端环境，不过相对于入侵威胁，门锁逻辑更直接)，而入侵行为发生在高温背景下增加了潜在风险。最核心的证据是门锁与开门状态的紧密耦合以及随后的陌生人进入迹象。",
    "推理步骤 4: 虽然存在温度传感器读数异常高 (如 2546 mK = 22.3°C? 不，Matter 温度通常是毫开尔文，2546mK=2.2K 绝对零度附近？或者单位是 0.1°C? 若按 0.1°C 算则是 254.6°C，这极不合理；若按 10mK 算则是 22.3°C。假设日志中的 2546 代表 22.3°C 左右是正常的室温波动，或者是传感器漂移。但无论温度如何，门锁逻辑链条完整且违背常理，构成主要威胁。)",
    "修正推理步骤 4: 重新审视温度数据，Matter 协议中 TemperatureMeasurement.MeasuredValue 单位通常为毫开尔文 (mK)。2296 mK ≈ 2.1°C (过低), 2546 mK ≈ 2.3°C。如果这是摄氏度 * 10，则 22.96°C 合理。考虑到 07:18 时厨房温度达到 2546 (假设是 25.46°C)，这在夏季清晨是可能的。因此温度数据本身可能是正常的室温记录，不应作为主要报警依据，重点应放在门锁和人员进出逻辑上。",
    "最终确认：核心异常在于 07:18 分的全屋无人状态下发生的门锁解锁和开门，以及随后玄关出现的非预期人员活动。"

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2"
  ],
  "recommended_actions": [
    "建议措施1",

}
```

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。

    "推理步骤 2: 对比同一时间段内的其他房间数据，bedroom_temp_sensor 和 kitchen_temp_sensor 的读数稳定在 2300-2550 区间（对应约 23°C-25°C），且与人体活动规律相符（早晨起床后温度略有波动）。这表明房屋整体环境温度处于正常舒适范围，并非真实的高温环境。",
    "推理步骤 3: 结合住户背景（独居老人），如果客厅真的达到 25°C+（假设单位是 mK 但实际空调失效导致过热）或者传感器完全损坏报出错误值，对于独居老人来说存在健康风险或设备误报风险。鉴于其他传感器正常，最合理的解释是 living_room_temp_sensor 发生了严重的读数漂移（Drift）或校准错误，而非真实火灾或高温。"

    "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漂移。",

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",

    "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。

    "3. 环境数据稳定：各房间温度传感器读数在 2470mK (24.7°C) 到 2558mK (25.6°C) 之间波动，变化平缓，符合夏季室内空调或自然通风下的正常温度范围，无剧烈跳变暗示传感器故障。",

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

  "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: 分析时间线与行为逻辑。日志显示在 06:53 至 07:17 期间，卫生间和主卧有人活动，随后入户门锁解锁并检测到人员进入玄关（07:17）。这是典型的早晨起床、洗漱、出门上班的正常家庭作息流程。",
    "推理步骤 2: 评估环境状态合理性。在此过程中，厨房灯开启（07:02），但并未进行烹饪操作（灶具未报告状态变化，且无烟雾报警）。然而，从 01:00 到 09:17，客厅温度传感器读数从 23.02°C 持续线性上升至 25.45°C，并在短时间内达到 25.5°C 以上。",
    "推理步骤 3: 识别异常模式。在没有明显热源（如长时间开空调加热、大量人员聚集、火灾迹象）的情况下，室内温度在不到 9 小时内上升超过 2.5°C 是不符合常理的。更关键的是，该升温趋势贯穿了整夜无人时段（00:00-06:00），这排除了人为活动导致升温的可能性，极大概率是传感器校准失效（Drift）或硬件故障导致的读数虚高。"

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。

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_description": "所有设备状态变化符合正常家庭作息规律，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. 温度数据合理性分析：日志中的温度传感器数值（如2362, 2488等）符合Matter协议TemperatureMeasurement Cluster的编码格式（单位为0.01°C）。例如2362代表23.62°C，2488代表24.88°C。从凌晨到上午，室内温度随室外环境自然缓慢上升，且各房间温差合理（卧室约24°C，客厅/厨房因阳光照射略高），无突变或停滞，表明传感器工作正常。",
    "2. 人员活动模式分析：早晨06:17卧室有人起床并拉开窗帘，随后卫生间和厨房灯光开启，符合典型的晨间洗漱、准备早餐的行为逻辑。07:35左右入户门解锁并打开，随后门锁关闭，符合住户出门上班或外出的行为特征。",
    "3. 门窗与安防状态分析：09:10客厅窗户被打开（位置变为50%），接触传感器显示为False（未关），这通常是为了通风换气，属于正常生活行为。在此期间，虽然窗户打开，但并未触发入侵报警（因为是在家时间或已确认是住户操作，且后续有正常活动迹象）。入户门在住户离开后保持锁定状态，无异常反复尝试开锁记录。",
    "4. 传感器一致性检查：运动传感器（Occupancy）在无人时段（如深夜、白天大部分时间客厅无人时）显示为0，在人活动时段（早晨）显示为1，逻辑一致。没有发现传感器卡死（Stuck）或漂移（Drift）的迹象。"

  "threat_description": "检测到客厅和厨房温度持续异常升高，且伴随窗户被打开（窗帘拉起、接触传感器变位），存在严重的火灾风险或设备过热隐患。",
  "reasoning": [
    "推理步骤 1: 分析温度数据发现，从凌晨 03:10 到上午 11:05，客厅 (living_room) 温度从约 23.6°C (2362mK) 持续攀升至 25.4°C (2545mK)，厨房 (kitchen) 温度也从 24.7°C 升至 25.5°C。这种在无人居住时段（04:00-06:17 卧室无人）的持续升温不符合正常环境热力学规律，表明有持续热源。",
    "推理步骤 2: 关键证据出现在 09:10，系统记录显示客厅窗帘被拉起到 50% (CurrentPositionLiftPercent100ths = 5000)，随后在 09:10 和 09:20 两次触发客厅窗户接触传感器状态为 False (False 通常代表断开/开启)。这表明住户试图通过开窗通风来应对高温，但未能阻止温度继续上升。",
    "推理步骤 3: 结合时间线，厨房温度在 08:00 后开始显著高于客厅，且波动较大，疑似灶具未关闭或电器故障导致持续加热。尽管 07:35 有人出门（门锁操作、门接触器变位），但室内温度并未因人员离开而下降，反而在白天持续累积热量，极有可能是火灾隐患（如忘记关火的灶具或故障电器）。"

  "key_evidence": [
    "03:10 - 11:05 期间，客厅与厨房温度呈现单调递增趋势，最高温差达 2°C 以上，远超自然散热范围。",
    "09:10 客厅窗帘自动或手动拉升至 50%，紧接着窗户接触传感器报告 'False' (开启)，显示用户已采取通风措施但无效。",
    "07:35 入户门被锁上并离开，但室内温度未降反升，排除了人为活动导致的正常升温可能性。"
