## 任务
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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: ..."
  ],

    "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: 正常样本是短时起夜；异常样本在厨房等非卧室区域停留过久。"
  ],
  "key_evidence": [
    "正常样本是短时起夜；异常样本在厨房等非卧室区域停留过久。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "health_concern",
  "threat_description": "独居老人在凌晨时段出现长时间无活动且卧室灯光异常开启，随后伴随室内温度持续异常升高，疑似老人夜间跌倒或突发疾病导致无法移动。",
  "reasoning": [
    "推理步骤 1: 时间窗口分析。日志显示在 2026-07-15T02:18:00 至 03:55:00 之间（约 1.5 小时），所有房间的运动传感器（living_room, bedroom, kitchen, bathroom, entrance）均报告 Occupancy = 0，表明屋内无人移动。",
    "推理步骤 2: 行为模式矛盾。在长达 1.5 小时的无人状态下，卧室灯（bedroom_light）却在 T02:18:00 被打开，并在 T05:21:05 再次被打开。对于独居老人而言，深夜起床开灯后若长时间未离开卧室或进行其他活动，极可能意味着老人已失去行动能力（如跌倒、中风或昏迷）。",
    "推理步骤 3: 环境数据佐证。在此期间，客厅和厨房的温度传感器读数持续攀升（从约 22°C 升至 24°C+），而卧室温度也呈上升趋势。这种升温可能是由于空调/暖气系统因无人操作而处于非节能状态持续运行，或者是老人身体发热导致的局部微环境变化，结合“无人 + 开灯”的孤立状态，进一步印证了老人被困在室内的可能性。"
  ],
  "key_evidence": [
    "2026-07-15T02:18:00 至 03:55:00 期间全屋运动传感器持续报空 (Occupancy=0)，但卧室灯在此区间内被激活。",
    "同一时间段内，客厅与厨房温度持续异常升高，且无任何人员活动记录来解释热源来源。",
    "目标用户为独居老人，该时段（凌晨 2 点至 4 点）属于高风险睡眠时段，长时间静止极易引发健康危机。"
  ],
  "recommended_actions": [
    "立即触发紧急警报并通知家属或社区紧急联系人。",
    "尝试通过智能家居语音助手呼叫老人确认状况。",
    "联系物业或急救中心上门查看，特别是考虑到老人可能跌倒无法动弹。"

## 任务
以下是过去 3 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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",

  ],
  "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。

  "reasoning": [
    "1. 入户门状态分析：日志中 front_door_contact 主要显示为 False（关闭）。7月14日07:06出现一次 True（开启），随后在10:20恢复为 False，这符合老人早晨出门或接收物品后关门回家的正常作息模式，无持续非法入侵迹象。",
    "2. 人员活动轨迹分析：多房间运动传感器（occupancy_sensor）在早晨至上午时段（08:00-10:30）频繁触发，覆盖客厅、厨房、卧室和玄关，表明老人在家中进行正常的晨间活动（如起床、洗漱、准备早餐等），未发现长时间静止不动导致的跌倒风险或异常静默。",
    "3. 环境与设备状态：温度传感器读数在合理范围内波动（约24-25°C），无极端值；烟雾报警器和漏水传感器无报警记录；门锁操作记录仅有一次手动上锁/解锁，与开门事件对应，无暴力破解或故障迹象。"

  "threat_description": "检测到疑似非法入侵行为：在独居老人外出期间，前门传感器多次报告“打开”状态（False），且伴随玄关区域异常频繁的人员活动信号，但无正常的开门/关门操作日志配合。",
  "reasoning": [
    "时间线分析：2026-07-13T06:54:04 和 2026-07-13T09:00:00 两次记录显示 front_door_contact 为 False（门开）。随后在 08:19、08:53、09:18、09:43 等时间点，entrance_occupancy 持续报告有人（Occupancy=1）。然而，在这些时间段内，没有任何 door_lock 的解锁操作日志（LockOperation），也没有后续的关门动作日志，这不符合正常住户出门后回家的逻辑。",
    "异常模式识别：在 2026-07-13 和 2026-07-14 的数据中，前门状态变为 False 后，玄关运动传感器立即或短时间内触发，且该区域人员存在性持续存在，直到当天较晚时候才恢复正常或出现关门迹象。这种‘门开 + 玄关有人’的组合在没有合法解锁指令的情况下，高度暗示外部人员进入。",
    "风险情境匹配：考虑到住户为独居老人，安全防御能力相对较弱。如果这是内部人员（如家人）进出，通常会有明确的门锁操作记录。缺乏锁具操作记录的门开启事件，结合持续的玄关活动，最可能的解释是窗户未关导致误报（但日志中窗户传感器未提及异常，且频率过高更像人为），或者是有人通过其他方式（如备用钥匙、技术开锁）进入并滞留玄关区域。鉴于频率之高（一天内多次），排除偶然因素，判定为入侵尝试或成功入侵。"

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
以下是过去 3 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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": [

    "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异常情况，设备日志显示独居老人的日常活动模式稳定且符合预期。",
  "reasoning": [
    "1. 活动规律性分析：过去三天（7月1日-3日），老人在早晨08:00-09:00期间有规律地出现在厨房、卧室和客厅，并在夜间23:50左右仍有活动记录，表明老人作息正常，无长时间失联或异常静止情况。",
    "2. 关键设备状态检查：日志中未出现烟雾报警器(smoke_co_alarm)、漏水传感器(water_leak_detector)的触发事件，排除了火灾和水患风险；入户门锁(door_lock)仅在08:27有一次手动开锁记录，随后进入室内活动，无非法入侵迹象。",
    "3. 传感器数据合理性：温度传感器读数在24°C-25.5°C之间波动，属于正常的室内环境温度范围，无极端值或传感器故障漂移迹象；运动传感器(occupancy_sensor)频繁上报'Occupancy=1'，符合老人在家中走动、停留的正常行为特征，并非传感器卡死（因为伴随位置变化）。"
  ],
  "key_evidence": [
    "连续三天早晨08:00-09:00期间，kitchen_occupancy, bedroom_occupancy, living_room_occupancy均有活跃记录，显示规律的日常起居。",
    "所有安全类传感器（烟雾、漏水）在日志片段中无任何报警事件。",
    "温度传感器数值稳定在舒适区间（约24-25摄氏度），无异常跳变。",
    "入户门仅在早晨08:27开启一次，之后无其他非授权开启记录。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",
    "建议定期校准温度传感器以确保长期数据准确性，尽管当前数据看起来正常。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",

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
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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。

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

  "threat_description": "独居老人在凌晨时段出现长时间无活动且卧室灯光异常开启，随后伴随持续高温，疑似夜间跌倒或突发疾病导致无法移动。",
  "reasoning": [
    "推理步骤 1: 时间分析。日志显示在 2026-08-19T02:10:00 至 03:50:00 期间，所有房间（包括客厅、卧室、厨房、卫生间）的运动传感器均报告 Occupancy = 0，表明屋内无人活动长达近 2.5 小时。对于独居老人而言，深夜长时间静止是高风险信号。",
    "推理步骤 2: 行为矛盾分析。在完全无人员活动的情况下，2026-08-19T02:18:00 卧室灯突然开启（OnOff.OnOff = True），且之后未再关闭。如果是正常起夜如厕，通常会有离开卧室的后续动作或再次进入的动作记录，但整个时间段内其他区域均为空，这暗示老人可能被困在卧室无法离开。",
    "推理步骤 3: 环境数据佐证。在此期间，客厅温度传感器读数从约 22°C (2274mK) 持续上升至 23°C+ (2388mK)，且厨房温度也同步升高。虽然空调可能未开，但人体体温或电器待机发热可能导致局部升温，结合‘人不动’和‘灯常亮’，极大概率是老人因健康原因（如中风、心脏病发作）或跌倒后无力起身，导致身体产热使室温微升，且无法关灯或移动。",
    "推理步骤 4: 排除误报。虽然 06:03 有短暂的卫生间占用记录，但这可能是家人查看情况或清洁工，距离异常发生已过去数小时。核心风险窗口（02:18-03:50）内无任何生命体征相关的移动迹象。"
  ],
  "key_evidence": [
    "02:10 - 03:50 期间全屋运动传感器持续报告 Occupancy = 0，形成长时间静默。",
    "02:18 在无人员移动的情况下，卧室灯异常开启并保持开启状态，违背正常睡眠/起夜逻辑。",
    "凌晨时段（02:00-04:00）室内温度呈现非正常的持续上升趋势，与无人活动的静态环境不符。"
  ],
  "recommended_actions": [
    "立即触发紧急警报并通知家属及社区紧急联系人。",
    "远程尝试通过智能音箱或预设语音指令询问老人状况（若设备支持）。",

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
{

  "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",

    "4. 排除误报：虽然部分occupancy传感器在短时间内有重复上报（如kitchen_occupancy多次上报为1），但这属于Matter协议中常见的状态保持或心跳机制，并非异常闪烁或故障。整体行为逻辑连贯，无孤立或矛盾事件。"

## 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",
  "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异常情况，设备日志显示住户活动规律，门窗状态正常。",
  "reasoning": [
    "1. 入户门状态分析：重点关注的 front_door_contact (BooleanState.StateValue = False) 在三天内多次出现（08:52, 09:00, 10:20, 08:50）。在 Matter 协议及常见智能家居逻辑中，False 通常代表“关闭/锁定”状态（Closed/Locked），True 代表“打开/未锁定”。所有记录均为 False，表明入户门始终处于关闭且锁定的安全状态，未发现非法入侵迹象。",
    "2. 住户活动模式分析：日志中 occupancy_sensor（运动传感器）在早晨 08:00-10:00 期间频繁触发（值为 1），涉及客厅、卧室、厨房和玄关。这符合独居老人起床后在主要生活区域活动的正常行为模式。没有发现长时间无活动（可能跌倒或昏迷）的异常静默期。",
    "3. 环境数据一致性：温度传感器读数在合理范围内波动（约 24°C - 25.5°C），且随时间缓慢变化，未见剧烈跳变导致传感器故障报警。漏水传感器和烟雾报警器在提供的片段中未触发任何告警事件。"
  ],
  "key_evidence": [
    "front_door_contact 连续多日保持 False (Closed)，无开启记录。",
    "早晨时段多个房间 occupancy_sensor 活跃，符合日常起居规律。",
    "无 smoke_co_alarm 或 water_leak_detector 的触发日志。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需紧急干预。",
    "建议定期校验 door_lock 的物理状态与 contact_sensor 的逻辑状态是否一致，以确保 False 确实对应物理上的‘已上锁’。"

  "threat_description": "客厅温度传感器报告的温度值（2500-2600）严重偏离物理现实，表明传感器故障或数据上报错误，可能导致基于此数据的自动化控制失效。",
  "reasoning": [
    "推理步骤 1: 分析日志中的温度数据，发现 living_room_temp_sensor 报告的 MeasuredValue 在 2505 到 2559 之间波动。",
    "推理步骤 2: 结合 Matter 协议标准及常识判断，该数值单位通常为毫开尔文 (mK) 或类似缩放因子，换算后约为 2.5°C 至 2.6°C。对于独居老人居住的夏季（8 月）家庭环境，室内温度不可能低至 2.5°C，这属于明显的物理异常。",
    "推理步骤 3: 对比同一时间段内其他房间（如 bedroom、kitchen）的温度读数（约 2437-2455 mK，即约 24.4°C），这些数值符合正常室温范围。唯独客厅传感器数据持续异常且与其他房间趋势不一致，排除了整体环境温度骤降的可能性，确认为单个设备故障（Sensor Malfunction）。",
    "推理步骤 4: 考虑到住户为独居老人，若空调系统依赖错误的低温反馈而停止制冷，可能导致室内过热；或者若烟雾/燃气报警器的联动逻辑被干扰，将构成安全隐患。"
