## 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",

## 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",

    "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_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的家庭日常活动及环境监控数据。",
  "reasoning": [
    "1. **人员活动模式分析**：日志显示儿童房（kids_room）在上午8:36至下午16:10期间持续有人（Occupancy=1），符合学龄儿童在家或放学后的正常作息。客厅（living_room）和主卧（master_bedroom）在下午时段也有人员活动记录，且入户门传感器（entrance_occupancy）多次触发，表明家庭成员在屋内正常走动，无异常静止或长时间无人迹象。",
    "2. **门禁与入侵检查**：16:00时，入户门锁执行了手动解锁操作（LockOperationType=1），随后入户门传感器状态变为False（通常表示门被打开或关闭，结合时间看可能是回家或出门动作）。此行为发生在白天，且有后续的人员活动支持，属于正常的进出行为，未发现非法入侵特征。阳台门传感器在16:12也记录了状态变化，同样处于正常活动时间窗口。",
    "3. **环境与设备状态**：温度传感器读数在24°C左右波动，数值格式符合Matter协议标准（厘度，即2472代表24.72°C），数值合理且无剧烈跳变，排除传感器故障或漂移。未检测到烟雾、一氧化碳或漏水报警信号。",
    "4. **综合判断**：所有事件均发生在合理的白天时间段，设备状态变化与人员移动逻辑一致，没有发现冲突、异常锁定、危险环境指标或可疑的闯入行为。"
  ],
  "key_evidence": [
    "16:00:00 front_door_lock | Event: LockOperation(LockOperationType=Manual) - 正常的手动开锁/关门行为",
    "08:36-16:10 kids_room_occupancy = 1 - 儿童房内持续有人，符合日常作息",
    "Temperature values ~2400-2500 (24-25°C) - 环境温度正常，无火灾或极端天气风险",
    "No smoke, CO, or water leak alarms detected - 无紧急安全警报"
  ],
  "recommended_actions": [
    "无需采取任何行动，系统运行正常。",
    "建议继续保持当前的自动化规则，确保门窗传感器与灯光/空调的联动逻辑符合用户习惯。"
  ]
}
```

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "child_safety",
  "threat_description": "儿童房在无人看管的情况下出现异常高温，且存在人员活动迹象，疑似发生过热风险或设备故障导致的环境失控。",
  "reasoning": [
    "推理步骤 1: 温度数据异常解读。日志中 kids_room_temp_sensor 报告的温度值（如 2472, 2457）远超正常室温范围（通常 20-30°C）。结合 Matter 协议标准及常见传感器格式，这些数值极有可能是以 0.01°C 为单位的原始读数（即实际温度为 24.72°C），或者是传感器漂移导致的错误高报。无论哪种情况，该房间在下午时段持续处于较高温度区间（24.0°C - 24.7°C），而同一时间其他房间（如 master_bedroom 24.0°C, kitchen 24.0°C）温度相对平稳或略低，需关注局部热点。",
    "推理步骤 2:  occupancy 与温度的时空关联分析。在 14:10 至 16:10 期间，kids_room_occupancy 频繁报告为 1（有人），且在此期间温度读数波动较大但未明显下降。更关键的是，在 16:00 入户门被手动上锁（LockOperation=1, LockState=2）后，直到 16:10 左右才再次检测到客厅有人，这意味着从 16:00 到后续时间点，家庭主要成员可能已离开或处于封闭状态，但儿童房内仍持续有‘人’的感应信号和较高的温度读数。",
    "推理步骤 3: 行为模式与安全隐患推断。如果儿童房内确实有人（Occupancy=1），且温度持续偏高（若按 24.72°C 理解则属正常偏暖，但若传感器故障导致读数虚高则危险；若按 247.2°C 理解则是严重火灾前兆，但考虑到与其他房间温差过大且无烟雾报警触发，更倾向于传感器单位误解或局部热源）。然而，最危险的场景是：如果 Occupancy=1 代表儿童在场，而家长（根据门锁操作推测）已离开家（16:00 锁门），此时儿童房内温度异常升高（假设实际温度因某种原因失控，或者传感器本身故障导致误报高温），构成了典型的“无人看管下的儿童安全风险”。此外，16:12 阳台门打开又关闭，增加了外部干扰的可能性。综合来看，儿童房在疑似家长离家的时间段内，存在温度异常波动和持续的人员占用信号，符合 child_safety 威胁特征。",
    "推理步骤 4: 排除法。没有烟雾报警器触发（smoke_co_alarm 未上报事件），排除了明火火灾；没有漏水传感器报警，排除水患。问题核心在于环境参数（温度）与人员状态（儿童可能在室内）的不匹配风险。"
  ],
  "key_evidence": [
    "2026-08-25T14:10:00 至 16:10:00 期间，kids_room_temp_sensor 持续报告异常高位数值（245x-247x），而其他房间温度相对稳定。",
    "2026-08-25T16:00:00 入户门锁被手动锁定（LockState=2），随后在 16:10 之前未见其他家庭成员进入儿童房的明确记录，但 kids_room_occupancy 仍保持为 1。",
    "儿童房温度读数与其他房间存在显著差异，且伴随持续的人员占用信号，提示可能存在局部过热或传感器故障导致的误判风险。"
  ],
  "recommended_actions": [
    "立即远程检查儿童房温度传感器的校准状态，确认读数是否准确（区分是 24.72°C 还是 247.2°C 或其他单位错误）。",
    "通知住户前往儿童房核实是否有儿童滞留，并检查房间内是否存在异常热源（如电器过热、阳光直射等）。",
    "若确认为传感器故障，建议暂时禁用该传感器并启用备用监测方案，同时检查空调/温控系统是否正常工作。",
    "审查儿童房的安全设置，确保在家长离家时自动开启额外的环境监测或联动警报。"

## 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。

{
  "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: 正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "key_evidence": [
    "正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在尝试通过键盘解锁时发生错误，随后状态异常变为未锁定（State=2），且发生在住户频繁进出期间。",
  "reasoning": [
    "推理步骤 1: 日志显示在 2026-08-17T18:05:00 时，front_door_lock 报告了 'LockOperationError(source=Keypad)'，表明用户尝试使用键盘操作失败。",
    "推理步骤 2: 紧接着在 2026-08-17T18:06:00，门锁状态变为 2 (通常代表 Unlocked/未锁定)。结合之前的错误事件，这极有可能是因为锁具故障导致无法正确执行上锁或保持锁定状态，而非用户手动打开。",
    "推理步骤 3: 虽然之后在 18:13:00 有成功的上锁操作 (LockOperationType=1)，但中间约 7 分钟的窗口期存在安全隐患。考虑到此时 entrance_occupancy 和 kids_room_occupancy 均为 1 (有人在家)，如果门锁在此期间失效，可能导致非法入侵风险增加，或者仅仅是设备本身的不稳定表现。",
    "推理步骤 4: 综合来看，门锁在关键时间点出现操作错误并伴随状态异常，属于典型的 lock_malfunction，需要立即关注以防止物理安全漏洞。"
  ],
  "key_evidence": [
    "[2026-08-17T18:05:00] front_door_lock | Event: LockOperationError(source=Keypad)",
    "[2026-08-17T18:06:00] front_door_lock | DoorLock.LockState = 2"
  ],
  "recommended_actions": [
    "立即检查入户门锁的物理机械结构及电池电量，排除因低电量导致的误报。",
    "建议联系专业维修人员对该门锁进行固件更新或硬件检修，确保其可靠性。",
    "在问题解决前，建议住户进出时采用手动钥匙双重确认，或暂时避免依赖电子键盘开锁。"

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",

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。

    "推理步骤 3: 在入户门打开后约 40 秒 (16:13:00)，客厅运动传感器 (living_room_occupancy) 从之前的 0 变为 1。考虑到入户门和阳台门均已打开，且之前客厅无人，这一运动信号极有可能是新进入者穿过玄关进入客厅所致，而非屋内原有人员的移动（因为屋内人员主要在儿童房，且若为屋内人员无需特意先开阳台门）。"

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",

## 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",
  "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。

  "is_anomaly": false,
  "confidence": "high",

    "1. 儿童房活动分析：kids_room_occupancy 在 08:17、11:22、14:27 等时间点多次触发（Occupancy=1），符合儿童白天在家活动的正常规律。虽然传感器频繁切换状态（如14:30-15:00间多次出现1和0的交替），但这通常是因为儿童在房间内小范围移动或静止导致的传感器灵敏度波动，属于正常现象，且伴随温度数据的稳定上报，无设备故障迹象。",
    "2. 家庭成员分布逻辑：15:21至16:04期间，master_bathroom、entrance、master_bedroom、dining_room 等多个区域同时检测到人员活动（Occupancy=1）。这符合多人口家庭在下午时段分散在不同房间进行洗漱、休息或用餐的正常生活场景，不存在入侵者单独行动或异常聚集的特征。",
    "3. 环境与设备状态：阳台门传感器（balcony_door_contact）在16:12变为False（关闭），与客厅 occupancy 在16:13变为1（有人）的时间点接近，可能是住户进出或整理门窗后的正常状态更新。所有温度传感器读数在23.8°C-24.7°C之间波动，处于舒适区间，无火灾或极端天气导致的异常高温/低温报警。",
    "4. 无关键安防事件：入户门锁（door_lock）未报告开锁或异常状态，烟雾报警器、漏水传感器均无报警记录。整体行为模式符合“三室两厅”家庭中父母与儿童共同生活的常态。"

  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器报告了异常的高数值（约 24.5°C x100），远超正常室温范围，且数值在短时间窗口内剧烈波动，疑似传感器故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 14:30 到 15:55，kids_room_temp_sensor 连续多次上报温度值分别为 2467, 2449, 2456, 2441 等。这些数值的单位通常是 0.01°C，换算后约为 24.67°C - 24.41°C。虽然换算后的温度看似合理，但原始整数值的波动幅度（如 2467 到 2449）对于同一房间在短时间内（几分钟）的变化来说过大，且数值本身（24xx）与其他房间（如 living_room 24xx, master_bedroom 24xx）的读数格式一致，但需结合上下文判断是否为误报。",
    "推理步骤 2: 重新审视数值逻辑。如果设备协议中温度测量值是以 0.01 为单位，那么 2467 代表 24.67°C。然而，观察后续数据：14:30 (2467) -> 14:35 (2449) -> 14:40 (2456)。这种在极短时间内（5-10 分钟）出现如此大幅度的跳变（差值达 18 个单位即 0.18°C），且伴随其他房间温度相对平稳下降的趋势（客厅从 2433 降至 2392），该传感器的数据表现出明显的非物理特性（噪声过大或不稳定）。",
    "推理步骤 3: 对比跨房间数据。在同一时间戳（如 15:20），客厅、主卧、厨房的温度读数分别为 2433, 2430, 2428，变化非常平滑。唯独儿童房在 14:30-15:00 期间出现了高频且大幅度的数值震荡（2467->2449->2456->2441...）。考虑到儿童房内有人活动（occupancy=1），如果是真实的热源导致温度快速升降，通常不会呈现这种锯齿状的随机波动模式，更符合传感器校准错误、信号干扰或固件 Bug 导致的 sensor_drift/malfeature 特征。",
    "推理步骤 4: 综合判断。虽然换算后的温度值（~24.5°C）并未达到危险的高温阈值（如 >35°C），但这种数据的不稳定性属于设备层面的异常（Sensor Malfunction/Drift）。如果该传感器用于联动空调或报警，错误的波动可能导致不必要的能源浪费或误触发警报，因此判定为设备故障风险。"
