## 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",

  ],
  "recommended_actions": [

}
```

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_type": "fire_risk",
  "threat_description": "厨房在无人状态下出现持续高温且伴随灯光开启，存在严重的火灾隐患。",
  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:05，此时独居老人通常处于睡眠状态（符合跨天摘要中卧室和客厅长时间无人的情况）。",
    "推理步骤 2: 异常行为识别。在 02:10 厨房运动传感器检测到有人 (Occupancy=1)，随后在 02:50 厨房灯被打开 (OnOff=True)。然而，从 02:30 开始直到日志结束，所有房间（包括厨房、卧室、客厅）的运动传感器均报告为 0 (无人)。这表明有人在深夜进入厨房后离开，或者传感器误报，但结合后续温度变化，更可能是有人短暂活动后离开，或设备故障导致‘幽灵’占用信号消失。",
    "推理步骤 3: 危险模式确认。最关键的是温度数据：厨房温度从 02:10 的约 23.4°C (2340 mK) 急剧上升至 04:00 的约 24.0°C (2404 mK)，并在短时间内达到峰值 2396-2404 mK (约 24°C)。虽然绝对温差不算极大，但考虑到这是夜间无人值守时段，且厨房灯被打开，这种持续的高温趋势极有可能是灶具未关闭导致的加热现象。对于独居老人，夜间忘记关火是典型的高风险场景。",
    "推理步骤 4: 综合判断。厨房灯开启 + 持续高温 + 无人状态 = 极高的火灾风险。烟雾报警器未在日志中触发报警事件，可能意味着尚未达到报警阈值，但风险已迫在眉睫。"
  ],
  "key_evidence": [
    "02:50 kitchen_light 状态变为 True (开灯)",

## 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: ..."
  ],

    "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": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "夜间长期停留在非卧室区域",
  "reasoning": [
    "推理步骤1: 深夜在非卧室区域持续活动",
    "推理步骤2: 时长明显超出普通起夜",
    "推理步骤3: 可能是迷路或意识混乱"
  ],
  "key_evidence": [

  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到厨房区域存在严重的火灾隐患：在无人活动的情况下，厨房温度持续异常升高并超过安全阈值。",
  "reasoning": [
    "1. 环境状态分析：从 02:10 到 04:10，厨房运动传感器（kitchen_occupancy）多次报告为 0（无人），且客厅、卧室等其他房间也处于无人状态，表明此时家中无人在场。",
    "2. 异常数据识别：尽管无人活动，厨房温度传感器读数却呈现持续上升趋势。从 02:10 的 2340 (°C*10) 即 23.4°C 开始，温度稳步攀升，至 03:55 达到 2399 (23.99°C)，并在 04:00 达到峰值 2410 (24.1°C)。",
    "3. 逻辑矛盾与风险推断：对于独居老人家庭，凌晨时段厨房温度在无人为干预下自然上升极不寻常。虽然数值看似未达明火燃烧的高温（通常>60°C），但结合 Matter 协议中常见的整数缩放比例（此处可能为 x10），若实际温度已达 24°C 以上且持续上升，或者该传感器本身发生了漂移/故障导致误报高温，均构成潜在风险。更关键的是，如果这是真实温度且持续上升，可能预示着灶具余热未散、电器过热或潜在的阴燃火情初期阶段，而住户因睡眠无法察觉。",
    "4. 排除正常行为：日志显示厨房灯（kitchen_light）在 02:50 开启，随后无人操作，温度却继续飙升，排除了正常烹饪后关闭电器的可能性，符合‘无人看管下的异常热源’特征。"

  "key_evidence": [
    "时间戳 2026-07-12T02:10:00 至 04:10:00 期间，kitchen_occupancy 持续为 0（无人）。",
    "同一时间段内，kitchen_temp_sensor 读数从 2340 线性增长至 2410，显示持续升温趋势。",
    "在此期间，living_room_occupancy 和 bedroom_occupancy 均为 0，确认屋内无人。"
  ],
  "recommended_actions": [
    "立即通过智能家居系统远程检查厨房摄像头画面（如有）或查看烟雾报警器状态。",
    "通知家属或紧急联系人，告知可能存在厨房安全隐患。",
    "建议用户起床亲自检查厨房，确认是否有电器过热、灶具未关或异味。",
    "检查厨房温度传感器是否校准正常，排除传感器故障导致的误报。"

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 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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "老人连续多天活动范围缩小",
  "reasoning": [
    "推理步骤1: 活动由多房间收缩到单一区域",
    "推理步骤2: 跨天持续出现",
    "推理步骤3: 提示功能退化或健康问题"
  ],
  "key_evidence": [
    "活动由多房间收缩到单一区域",
    "跨天持续出现",
    "提示功能退化或健康问题"
  ],
  "recommended_actions": [
    "判定为老人活动范围异常缩小，建议关注健康状态。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式稳定，设备状态与时间逻辑一致，未发现安全威胁或异常行为。",
  "reasoning": [
    "入住与离开模式正常：住户每天在早晨（约 07:20-08:30）和傍晚/夜间有规律的进出记录，且门锁操作（LockOperation）均为手动开启，符合独居老人起床后出门买菜或散步再返回的常规作息。",
    "环境参数合理：客厅温度传感器读数约为 25.4°C (2540 mK)，卧室约为 24.4°C (2440 mK)，厨房略高但处于烹饪正常范围，无过热或极端低温迹象；所有温度变化平滑，无突变漂移。",
    " occupancy 逻辑自洽：各房间的人员占用状态（OccupancySensing.Occupancy）随时间流动自然切换，例如从卧室移动到客厅再到厨房，没有出现长时间无人却频繁触发运动传感器的情况，也未发现人员进入后长时间静止不动的跌倒风险特征。",
    "关键安全设备工作正常：烟雾报警器、漏水传感器等未在日志中报出故障或触发报警事件，且窗户接触传感器未检测到非法入侵（如门开人未进或窗开人未动）。"
  ],
  "key_evidence": [
    "门锁事件 front_door_lock 仅在早晨和傍晚出现，且操作源为 Manual，无异常解锁尝试。",
    "温度传感器数据连续三天呈现稳定的昼夜波动曲线，数值均在舒适居住范围内。",
    "跨天摘要显示各房间活动频次（Event Count）高度一致，表明生活习惯未发生突变。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期检查老人身体健康状况，确保其独自生活的安全性。"
  ]

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",

    "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": "厨房温度异常升高且伴随人员活动，存在严重的火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:10，此时独居老人通常处于睡眠状态（卧室温度约 22-23°C），但厨房区域出现了异常的高温现象。",
    "推理步骤 2: 温度数据异常。厨房温度传感器读数从 02:10 的 23.35°C (2335 mK) 持续攀升，在 03:50 达到峰值 24.04°C (2404 mK)，随后略有下降但仍维持在 23.8°C 以上。对于无人值守的厨房，这种持续升温不符合正常散热规律，极可能是灶具未关闭或发生过热。",
    "推理步骤 3: 行为模式矛盾。虽然大部分时间厨房 occupancy 为 0，但在 02:10、02:35、02:50 等时间点检测到 occupancy=1。这表明有人在凌晨时段进入厨房并进行了操作（如开火），随后离开，导致设备处于“无人看管的高温”危险状态。同时，客厅和卧室均无人员活动，排除了全家醒着的可能性，增加了意外发生的严重性。",
    "推理步骤 4: 关联设备验证。厨房灯在 02:50 被打开，进一步证实了有人在该时间段的活动。结合持续升高的温度和烟雾报警器的存在，火灾风险极高。"
  ],
  "key_evidence": [
    "厨房温度在凌晨时段从 23.35°C 持续上升至 24.04°C，远超正常室温波动范围。",
    "在厨房温度急剧上升期间及之后，所有其他房间（卧室、客厅）均显示无人 (Occupancy=0)，表明是独居老人独自进行的操作且无人看护。",
    "厨房 occupancy 传感器在凌晨多次记录到有人存在，与温度异常上升的时间段高度重合。"
  ],
  "recommended_actions": [
    "立即远程通知住户或其紧急联系人，告知厨房可能存在火灾隐患。",
    "若系统连接当地消防部门或具备自动联动能力，建议触发警报或派遣救援。",
    "检查厨房烟雾报警器是否正常工作，并确认是否有烟雾报警信号上报。",
    "待安全后，需排查灶具是否存在故障（如熄火保护失效）或人为疏忽（忘记关火）。"

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 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

  "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",

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。
