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
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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",

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: 傍晚 18:22 记录到入户门锁被手动上锁（LockOperationType=1），紧接着 21:52 客厅灯光关闭且门锁再次被手动上锁（LockOperationType=0），这完全符合住户下班回家、活动结束并准备休息时的标准安防流程。",

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

  "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。

  "threat_description": "独居老人在凌晨 02:13 至 02:30 期间出现异常活动模式：门锁被打开后，客厅传感器短暂检测到有人，但随后在 5 分钟内连续多次报告无人，且室内温度持续异常升高，疑似老人夜间起夜如厕后晕倒或长时间滞留某处未移动。",
  "reasoning": [
    "推理步骤 1: 时间分析 - 事件发生在凌晨 02:11-02:13，属于独居老人高风险时段（夜间）。门锁状态变化（LockState=2 解锁）紧接着门接触传感器变 False（开门），随后玄关灯亮起，符合老人夜间起床活动的特征。",
    "推理步骤 2: 行为矛盾分析 - 02:13 客厅运动传感器检测到有人 (Occupancy=1)，但在随后的 02:30 之前，所有房间（包括客厅、卧室、厨房、卫生间）的运动传感器均连续报告无人 (Occupancy=0)。对于一个刚进入家中的独居老人来说，这种‘进门即消失’且全屋无人的状态极不自然，暗示老人可能并未正常行走至其他区域，而是静止不动或处于无法移动的状态（如跌倒）。",
    "推理步骤 3: 环境数据佐证 - 在此期间（02:15-02:45），客厅和厨房的温度传感器读数持续上升并达到峰值（客厅最高达 23.61°C，厨房 23.53°C），而卧室温度相对较低。如果老人正常活动，通常会伴随空调调节或门窗开启导致温度波动；若老人静止不动，其体温辐射可能导致局部微环境升温，或者是因为老人忘记关闭电器/窗帘导致室温累积升高。结合‘全屋无人’的传感器读数，最合理的解释是老人已失去行动能力，被困在某个角落（可能是客厅或门口附近），导致运动传感器因阈值或遮挡未能再次触发，同时环境温度因缺乏人员流动散热而异常积聚。",
    "推理步骤 4: 排除误报 - 虽然运动传感器可能存在盲区，但连续 17 分钟的全屋无人报告与刚刚发生的开门事件形成强烈反差。对于独居老人场景，这种‘夜间突发活动后迅速失联’的模式是典型的跌倒或健康危机前兆，而非简单的传感器故障（因为多个房间传感器一致报告 0）。"

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",

  ],

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 occupancy_sensor 数据发现，在 2026-08-07、08 和 09 的同一时间段（约 03:14），living_room_occupancy 均从 0 变为 1，但在约 15-20 分钟后（03:30 或 04:30）又变回 0。这种‘短促出现 - 消失’的模式对于独居老人来说极不寻常，通常意味着有人突然闯入或住户突发状况起身活动后立即停止行动/离开现场。",
    "推理步骤 2: 结合 temperature_sensor 数据，在老人出现的时段（03:14 之后），客厅温度从正常的夜间低温（~23°C）开始持续快速上升，并在 04:40 左右达到峰值（~24.2°C）。如果是正常起床活动，通常会打开空调或窗户降温，或者活动范围扩大导致其他房间温度变化；而此处仅客厅升温且无人长时间停留，可能暗示老人因身体原因（如发烧、中风前兆）被困在客厅，导致人体热量积聚，或者空调系统故障未能调节。",
    "推理步骤 3: 对比三天日志，该模式高度一致（每天凌晨 3 点多发生一次），排除了随机入侵的可能性（入侵者不会连续三天在同一时间精准作案并迅速撤离而不触发烟雾报警或其他反应）。考虑到住户是独居老人，这种规律性的深夜异常活动最符合‘健康危机’或‘意外跌倒后无法移动’的特征，属于高风险的安全隐患。"

    "在 occupancy 激活期间及之后，living_room_temp_sensor 读数呈现非自然的持续上升趋势（从 23.7°C 升至 24.2°C+），且未伴随空调开启或窗户打开的迹象。",
    "作为独居老人，凌晨时段出现此类‘短暂活动即消失’的行为与常规作息严重不符，且无其他设备（如厨房灶具、漏水传感器）联动报警。"

## 任务
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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。

  "reasoning": [
    "推理步骤 1: 凌晨 03:00 至 04:30 期间，全屋（包括入户门、客厅、卧室等）运动传感器均报告无人员 (Occupancy=0)，且门锁在 04:06-04:09 处于解锁状态 (LockState=1)，随后于 04:09 开启客厅灯光。结合时间判断，这是典型的住户离家后的正常‘布防’或‘外出’场景，而非入侵迹象。",
    "推理步骤 2: 07:31 的日志显示入户门锁执行了手动上锁操作 (LockOperationType=1)，紧接着在 16:15 和 18:02 又分别记录了两次手动上锁操作。这些时间点（早晨出门、下午回家/离开）符合日常作息规律，且操作源均为 Manual，表明是住户自主控制。",
    "推理步骤 3: 整个日志片段中，所有设备状态变化（开门、关门、开灯、上锁）的时间间隔合理，没有检测到异常的设备行为模式（如未授权访问尝试、传感器数据冲突或长时间异常静止），因此判定为正常家庭活动。"
  ],
  "key_evidence": [
    "凌晨时段全屋 occupancy 持续为 0，符合夜间无人特征。",
    "门锁操作记录 (07:31, 16:15, 18:02) 与典型的人类起床和归家时间吻合，且均为手动操作。",
    "04:09 开启客厅灯光发生在门锁解锁后不久，逻辑连贯，属于住户返回家中开灯的正常行为。"

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。

    "修正推理步骤 3: 重新审视 LockState 定义。通常 1=Unlocked/Open, 2=Locked。22:02 时 LockState 变为 1 (Unlocked)。虽然此时屋内无人 (基于之前的 occupancy 趋势和关灯行为)，但这可能是用户睡前故意留门通风，或者是用户忘记上锁。然而，对比整个日志的时间跨度，从早上出门到晚上回家再到深夜，没有任何外部强行进入的迹象（如门锁反复尝试、接触传感器异常触发）。这种‘未上锁’状态如果是用户主动行为（如留门），则属正常；如果是疏忽，风险较低。鉴于缺乏其他异常证据（如窗户传感器报警、烟雾报警等），将其判定为正常行为模式中的轻微疏忽或特定习惯，而非恶意入侵。",

## 任务
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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",

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。

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：

  "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。

    "推理步骤 4: 如果系统直接将这些原始数值解释为摄氏度，会触发最高级别的火灾警报；即使系统有单位转换逻辑，如此剧烈的非物理性波动也属于典型的 sensor_drift 或 sensor_malfunction，必须立即处理以防止安全系统误判。"

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。
