## 任务
请从下面 3 天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",

    "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",

  "threat_description": "未检测到安全威胁或异常行为，日志显示为正常的家庭日常活动及环境变化。",

    "1. **活动模式分析**：7月24日为典型的工作日早晨，住户在06:30-08:50期间依次起床（主卧、儿童房、餐厅），并在09:00左右离开客厅，符合正常作息。20:33的晚间活动也属于正常居家状态。",
    "2. **设备操作逻辑**：厨房灯在07:41关闭，随后门锁在07:41-07:42被手动锁定并进入锁定状态，玄关传感器显示有人，这符合住户出门上班/外出的标准流程（关灯、锁门、离家）。",
    "3. **温度数据解读**：所有温度传感器的读数（如2496, 2512等）均处于合理范围内（对应约24.9°C - 25.3°C），且随时间推移有自然的波动和下降趋势（如7月26日傍晚降至23°C以下），表明传感器工作正常，无漂移或故障。",
    "4. **无危险迹象**：日志中未出现烟雾报警器触发、漏水传感器报警、灶具长时间开启无人看管、或非法入侵（如非授权时间的门锁开启）等高风险事件。"
  ],
  "key_evidence": [
    "07:41 kitchen_light OnOff=False 与 07:41 front_door_lock LockState=1 (Locked) 连续发生，符合离家场景。",
    "TemperatureMeasurement.MeasuredValue 数值稳定且在人体舒适区间内，无突变或极值。",
    "OccupancySensing.Occupancy 变化序列（0->1->0）符合人员进出房间的正常逻辑。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则（如离家自动锁门、人来灯亮等）。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",

## 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",

  "reasoning": [
    "1. **入户行为分析**：18:00左右，门锁执行了手动解锁（LockOperation=Manual），随后门磁传感器显示门打开（False）并关闭（True）。紧接着玄关灯亮起，客厅 occupancy 传感器检测到有人进入，且用户开启了客厅灯光和空调。这一系列动作符合典型的“下班回家”场景，逻辑连贯，无异常闯入迹象。",
    "2. **设备状态一致性**：在人员进入后，客厅灯光（living_room_light_1）和空调（living_room_ac）被开启，温度传感器读数随后开始下降（从约23.16°C降至22.95°C），表明空调正在制冷，设备响应正常。",
    "3. **传感器数据合理性**：虽然温度传感器的数值（如2380, 2376等）看起来较大，但结合上下文（18:00后数值下降至2295等），这显然是以0.1摄氏度为单位或特定编码的温度值（例如23.80°C）。所有房间的温度变化趋势平缓且符合物理规律，未发现传感器卡死（stuck）或漂移（drift）导致的异常恒定值。",
    "4. **无其他风险信号**：厨房灯仅在早晨短暂开启，晚间未检测到灶具使用或烟雾报警；卫生间漏水传感器、一氧化碳报警器均无触发记录；门窗传感器仅在正常出入时触发。"

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
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_description": "未检测到安全威胁，日志显示为正常的家庭日常活动模式。",
  "reasoning": [
    "1. 活动模式分析：日志涵盖了2026-07-21至2026-07-23的三天数据。各房间（客厅、主卧、儿童房等）的运动传感器在白天和傍晚时段频繁触发（Occupancy=1），夜间或无人时归零（Occupancy=0），符合典型家庭成员在家活动的规律。例如，7月21日早晨多个房间陆续有人活动，7月23日傍晚入户门解锁后灯光亮起，均为正常生活场景。",
    "2. 设备状态检查：重点关注的厨房灯（kitchen_light）仅在特定时间点开关（如7月21日07:14关闭，7月22日06:31开启，7月23日18:40开启），且伴随其他房间的活动或温度变化，未发现长时间无人却持续亮灯或异常闪烁的情况。入户门锁在7月23日17:58有手动开锁记录，随后玄关/客厅灯光亮起，表明是住户回家，非非法入侵。",
    "3. 环境参数合理性：温度传感器读数（如2487, 2504等）在Matter协议中通常表示摄氏度乘以100的值（即24.87°C, 25.04°C），数值随时间缓慢波动，符合室内环境温度变化趋势，无突变或传感器卡死迹象。",
    "4. 跨天一致性：三天的活动摘要显示各房间活跃度稳定，没有异常的静默期或突发的全屋活跃，进一步佐证了系统的正常运行和住户行为的连续性。"
  ],
  "key_evidence": [
    "7月23日17:58入户门锁Manual开锁，紧接着17:58客厅灯亮起，18:13玄关运动传感器触发，符合住户回家回家的正常逻辑。",
    "厨房灯在7月21日07:14关闭，当时厨房温度传感器仍在上报数据，且后续无异常高温报警，排除未关火风险。",
    "所有温度读数（如24.87°C - 25.53°C）均在舒适范围内且变化平缓，无传感器故障特征。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控厨房区域，确保烹饪结束后灶具和灯光确实关闭，以维持节能和安全习惯。"
  ]
}
```

{
  "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": [
    "正常样本仍有零星厨房活动；异常样本连续多天完全缺失相关使用。"
  ],
  "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
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。

## 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",

    "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_description": "厨房温度传感器数据严重异常，数值高达 2700+ (应为 23-28°C)，且伴随烟雾报警器未触发，极可能是传感器故障或校准错误导致误报风险。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，从 18:05 开始，厨房温度传感器读数出现剧烈且不符合物理规律的跳变（从正常的 24°C 左右瞬间飙升至 2463, 2517, 直至 2714）。",
    "推理步骤 2: 对比其他房间传感器数据，客厅、主卧、次卧的温度均在正常范围（229-235 之间），说明环境温度并未发生极端变化，排除了真实火灾或高温环境的可能性。",
    "推理步骤 3: 尽管厨房温度显示异常高，但日志中厨房烟雾报警器(smoke_co_alarm)和灶具(cook_surface)的状态均为静默或未报告报警事件。如果真实发生火灾或过热，烟雾报警器应已触发。这种‘高温无烟雾’的矛盾现象强烈指向传感器硬件故障、固件 Bug 或通信协议解析错误（Sensor Malfunction）。",
    "推理步骤 4: 虽然用户随后开启了灶具(18:51)，但这发生在异常读数出现之后，因此不能解释之前的异常高温数据。该异常读数可能导致系统误判为火情而采取不必要的紧急措施，或者掩盖真实的早期火情信号（如果传感器逻辑被破坏）。"

  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数严重偏离物理现实，显示异常高温（约 250°C+），而厨房和卧室温度正常，表明传感器故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 2026-07-22T06:25:00 开始，living_room_temp_sensor 的 MeasuredValue 持续在 2484 到 2556 之间波动。由于 Matter 协议中温度通常以 0.01°C 为单位，该数值实际代表 24.84°C 至 25.56°C，这是正常的室温范围。然而，若系统未进行单位转换直接展示原始值，或者用户/系统期望看到的是摄氏度但收到了毫摄氏度或其他单位的原始数据，则会产生误解。但更可能的情况是：观察其他设备如 kitchen_temp_sensor (2518 -> 2552) 和 bedroom_temp_sensor (2424 -> 2434)，它们的数值变化趋势与 living_room 一致且都在合理范围内（假设单位统一）。",
    "重新评估推理步骤 1: 让我们再次仔细检查数值的合理性。如果单位是摄氏度，2500°C 显然不可能。如果单位是毫摄氏度 (mCelsius)，那么 2500 mC = 25.00°C，这是完全合理的室温。因此，仅凭数值本身不能判定为 sensor_drift，除非有证据表明单位设置错误导致显示异常。",
    "推理步骤 2: 寻找真正的异常模式。注意到 2026-07-22T07:30:12 到 07:30:19 期间的事件序列：front_door_lock 先变为状态 2 (Unlocked)，紧接着 front_door_contact 变为 True (Door Open)，随后 front_door_lock 变为状态 1 (Locked)。这是一个标准的开门 - 关门流程，符合住户早晨出门的习惯。",
    "推理步骤 3: 深入挖掘跨天活动摘要中的异常。对比三天数据：2026-07-22 bedroom=219, 2026-07-23 bedroom=67, 2026-07-24 bedroom=218。卧室运动传感器在中间一天（7 月 23 日）的活动量骤降为平时的 1/3，而在前后两天均保持高活跃度（~219）。同时，7 月 23 日的 living_room_occupancy 在白天大部分时间（10:30-13:30）均为 0，直到晚上才有人出现。这种‘白天卧室无人、夜间突然活跃’的模式，结合前一日和后一日的高频卧室活动，极不寻常。",
    "推理步骤 4: 结合上下文判断威胁类型。住户通常在白天（工作/学习）和晚上（休息）都会使用卧室。7 月 23 日白天卧室传感器几乎无触发（仅 67 次 vs 其他天的 219 次），且客厅长时间无人，这不符合常规作息。最可能的解释是：有人在白天进入了房屋并躲藏在卧室（可能是入侵者），但由于某种原因（如窗帘遮挡、传感器角度问题或故意规避）未被检测到，或者住户本人因故全天未进入卧室。考虑到前后两天的规律性，'intrusion'（入侵）的可能性较高，因为入侵者可能会选择白天潜入并在隐蔽处待命，或者住户外出时有人尾随进入。然而，更直接的证据缺失。",
    "修正推理步骤 4: 让我们重新审视温度数据。如果所有温度传感器都报告了 25xx 这样的数值，且厨房和卧室也类似，那么这很可能是正常的室温（25°C左右），只是日志记录了原始整数部分或特定格式。没有单一的温度异常。",
    "最终确认异常点：回到 7 月 23 日的卧室活动量骤降。正常情况下，住户在白天（10:00-18:00）应该会在卧室活动（起床、午休、回家等）。7 月 23 日白天卧室 occupancy 计数极低（67 次），而前后两天高达 219 次。与此同时，7 月 23 日 10:30-13:30 客厅无人。这种反常的‘静默期’在安全监控中是一个强烈的信号。虽然不能完全排除住户当天特殊安排（如全天在办公室且不在家，但这与 7 月 22 日和 24 日的模式不符，且 7 月 23 日晚上有人回来），但在缺乏外部信息的情况下，这种显著的行为偏差应被视为潜在的'behavioral_anomaly'或'intrusion'风险（例如入侵者在白天潜伏）。鉴于卧室是主要休息区，白天的极度安静值得高度警惕。",
    "再次检查日志细节：7 月 23 日 12:07:28 bedroom_occupancy = 0，12:10 卧室温度 2423，12:25 2415，12:50 2402。温度在缓慢下降，说明房间可能无人且空调关闭或自然冷却。这与前后两天白天卧室有人时的温度波动不同。综合来看，7 月 23 日白天的低活动量是核心异常。",
    "结论：最显著的异常是 7 月 23 日卧室运动传感器活动量的急剧下降，与前后两天形成鲜明对比，暗示可能存在非正常居住行为（如入侵者潜伏或住户异常缺席）。"
