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",

    "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。

Chosen response:
{
  "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": [

Rejected response:

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "客厅温度传感器数据严重异常，数值高达 2500+ (应为 24-26°C)，且与厨房、卧室温度读数存在逻辑矛盾，疑似传感器故障或通信错误。",
  "reasoning": [
    "推理步骤 1: 分析温度数据范围。日志中所有温度传感器的 MeasuredValue 均在 2370-2536 之间。若单位为毫摄氏度 (mK)，则对应 23.7°C - 25.3°C，符合常理；但若直接解读为摄氏度，则显示室温高达 2500°C，这在家庭环境中是不可能的物理状态。",
    "推理步骤 2: 检查跨房间逻辑一致性。在 2026-07-29T06:10:00，厨房灶具开启 (OnOff=True) 且厨房温度读数为 2482 (异常高值)，而同一时刻卧室温度为 2390 (相对正常)。随后在 2026-07-29T06:30:00，客厅无人 (Occupancy=0)，但温度却飙升至 2501。如果这是真实的高温，无人的客厅不应比有人活动的厨房和卧室更热，且高温应导致空调自动调节或触发烟雾/过热报警，但日志中未见相关联动。",
    "推理步骤 3: 识别模式特征。该异常持续出现在三天日志的白天时段，且数值呈现非自然的线性增长或波动（如从 2458 升至 2536），而非受环境温度影响的自然变化。考虑到住户为独居老人，设备误报可能导致其忽视真实的火灾风险，或者因设备故障导致无法正确监测环境，属于高风险的传感器失效场景。",
    "推理步骤 4: 排除其他可能性。虽然可能是单位转换问题，但在 Matter 协议的标准实现中，TemperatureMeasurement 通常以 mK 为单位。然而，即使假设是 mK，数值 2536mK = 25.36°C 是正常的，但为何只有客厅传感器一直报出如此高的“绝对值”而其他传感器有时正常？更可能的情况是：该传感器固件 bug 导致上报了 raw value 而非 scaled value，或者传感器硬件损坏导致信号溢出。无论哪种，都构成了 sensor_malfunction。"
  ],
  "key_evidence": [
    "2026-07-29T06:30:00 客厅无人但温度报告为 2501 (远超合理范围)",
    "2026-07-30T08:25:00 客厅温度达到峰值 2536，而此时厨房和卧室温度仅为 2497 和 2420，温差逻辑不合理",
    "温度数值随时间推移呈现不自然的单调递增趋势，不符合热力学平衡规律"
  ],
  "recommended_actions": [
    "立即联系智能家居服务商或设备制造商，要求重置并校准客厅温度传感器",
    "在维修期间，建议老人使用独立的机械式温度计手动监测客厅温度，以防真实过热未被发现",
    "检查客厅空调是否正常工作，因为如果传感器读数错误，空调可能不会启动制冷，导致真实室温过高"

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。

## 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。

Chosen response:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "threat_description": "电器运行时间异常长",
  "reasoning": [
    "推理步骤1: 设备持续运行超过常规时长",
    "推理步骤2: 倒计时未按预期减少",
    "推理步骤3: 存在过热或故障风险"
  ],

  ],

}

Rejected response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示厨房洗碗机正在正常运行，室内温度变化符合自然规律，无入侵、火灾或设备故障迹象。",
  "reasoning": [
    "1. 设备状态分析：厨房洗碗机 (kitchen_dishwasher) 在 14:00 启动 (OperationalState=1)，并在后续时间点报告倒计时 (CountdownTime)，表明其处于正常的运行周期中，未出现卡死或异常停止。",
    "2. 环境数据合理性：厨房温度传感器读数约为 25°C (2523 mK)，卧室和客厅温度随时间缓慢下降（从约 24°C 降至 23°C），这符合傍晚时分无人居住且空调关闭后的自然散热趋势，数值波动在正常范围内，无传感器漂移或故障特征。",
    "3.  occupancy 模式匹配：所有房间的运动传感器 (occupancy_sensor) 均持续报告为 0 (无人)，这与跨天摘要中提到的低活动量一致，且与洗碗机自动运行的场景相符（用户可能已离开厨房去其他区域或外出）。",
    "4. 安全设备状态：日志中未出现烟雾报警器、漏水传感器或门锁的报警事件或状态变更，关键安全设备似乎工作正常。"
  ],
  "key_evidence": [
    "kitchen_dishwasher | OperationalState.CountdownTime = 5400 (表明洗碗机正在按计划运行)",
    "living_room_occupancy / bedroom_occupancy / bathroom_occupancy 持续报告 Occupancy = 0 (与环境背景一致)",
    "kitchen_temp_sensor 读数稳定在 24-25°C 区间，无急剧升高或异常跳变"
  ],
  "recommended_actions": [
    "无需立即干预，系统运行正常。",
    "建议继续监控洗碗机完成后的状态，确保其能正常结束循环并复位。"
  ]

System:
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。
