## 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
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_type": "none",

  "threat_description": "儿童房温度传感器读数异常（数值高达 2300+），远超物理可能范围，且伴随数据丢失，表明传感器故障或通信错误。",
  "reasoning": [
    "推理步骤 1: 分析日志发现从 16:25:00 开始，kids_room_temp_sensor 报告的 MeasuredValue 为 2391、2381、2373 等数值。在 Matter 协议中，温度通常以 0.01°C 为单位存储，因此 2391 代表 23.91°C，这在物理上是合理的室温。然而，随后的数值如 18:39:00 的 'None' 和整体趋势显示该设备行为不稳定。",
    "推理步骤 2: 重新审视数值逻辑：如果系统未进行单位转换直接上报原始值，2391 意味着 239.1°C，这会导致火灾报警触发。但结合上下文，其他房间温度正常（约 23°C），若儿童房真的达到 239°C，烟雾报警器应早已报警。更可能的情况是：传感器固件 Bug 导致单位混淆（例如将 mK 误报为 C 但未除以 100，或者内部寄存器溢出/错误映射），或者传感器硬件损坏导致随机乱码。",
    "推理步骤 3: 关键证据在于 18:39:00 该传感器报告了 'None' (Null)，紧接着在 18:40:00 又恢复了看似正常的 2296 (22.96°C)。这种“高值乱码 -> 空值 -> 恢复正常”的模式是典型的传感器故障或通信丢包特征，而非真实的温度波动。虽然当前读数已回落至正常范围，但之前的异常高值（如果是真实物理量）构成了潜在的安全隐患（如过热风险被掩盖），且设备可靠性存疑。",
    "修正推理步骤 3 (基于常见 IoT 陷阱): 实际上，2391 极有可能是 **单位错误** 或 **数据解析错误**。如果设备配置错误，将毫开尔文 (mK) 当作摄氏度 (°C) 上报，2391 mK = 2.391 K (绝对零度附近)，不合理；若将某种内部编码直接当温度，则完全无意义。最合理的解释是：**传感器发生了漂移或校准失败，导致输出超出有效量程的噪声数据**。尽管后续数据恢复正常，但出现此类极端异常值表明传感器状态不可信，属于 sensor_malfunction。"

    "2026-08-04T18:39:00 该传感器突然返回 'None' (Null)，随后在 18:40:00 恢复为 2296，显示出典型的数据中断和恢复模式。"

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",

  ],
  "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。

{

  "threat_description": "儿童房温度传感器报告了异常的高数值（约 23.7°C * 100 = 2370+），随后数值持续下降且与其他房间温差逻辑不符，表明传感器可能故障或漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 16:30 至 17:40 期间连续上报的温度值分别为 2377, 2374, 2362, 2357, 2349, 2338, 2331 (单位推测为 mK 或类似放大倍数，即 23.7°C - 23.3°C)。虽然这些绝对温度值本身在舒适范围内，但结合上下文看，这些数值的精度和变化模式值得注意。",
    "推理步骤 2: 对比同一时间段内其他房间的温度传感器数据：master_bedroom (2361->2339), kitchen (2360->2339), living_room (2359->2329)。所有房间温度都在正常波动范围内（约 23.0°C - 23.6°C）。",
    "推理步骤 3: 关键异常点在于 18:00 时，kids_room_temp_sensor 突然跳变为 2317，而 master_bedroom 和 kitchen 在同一时刻分别为 2318 和 2315。如果 kids_room 之前是 23.7°C，现在变成 23.1°C，这种快速降温在没有空调开启记录的情况下是不合理的。更可能的解释是，之前的读数（2377-2331）实际上是传感器故障导致的数值漂移或校准错误（例如将 23.7°C 误报为 2377 的某种编码，或者传感器内部基准偏移），导致其读数序列与物理环境和其他传感器的相关性断裂。此外，18:57 厨房温度显示 None，也暗示可能存在网络或传感器通信不稳定，增加了 kids_room 传感器数据不可靠的可能性。",
    "推理步骤 4: 考虑到这是儿童房，温度传感器的准确性至关重要。持续的、无法用环境变化解释的数值异常（特别是相对于其他传感器的一致性偏差）被归类为 sensor_malfunction 或 sensor_drift。鉴于数值从高位（2377）逐渐‘回落’到与其他房间一致的水平（2317），这更像是传感器复位或故障恢复的过程，而非真实的温度变化。"

  "key_evidence": [
    "kids_room_temp_sensor 在 16:30-17:40 期间读数维持在 2370+ 区间，显著高于随后及同时段其他房间的温度趋势。",
    "18:00 时 kids_room_temp_sensor 读数突降至 2317，与其他房间（~2315-2318）趋于一致，表明之前的读数存在系统性偏差或故障。",
    "18:57 kitchen_temp_sensor 返回 None，佐证了该时段可能存在设备通信或状态异常。"
  ],
  "recommended_actions": [
    "立即检查儿童房温度传感器的硬件连接和电池状态。",
    "重新校准或重置儿童房温度传感器。",
    "在修复前，建议家长手动监测儿童房实际温度，确保无过热风险。",

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。

    "场景推理：如果儿童房内真的有人（传感器显示 Occupancy=1），且温度高达 24.75（假设是某种极端情况）或传感器本身故障导致读数混乱，而家长并未立即干预（直到 16:10 才开门锁并开灯），这种‘高温/乱码’与‘持续有人’的长期共存状态构成了潜在的安全隐患。特别是考虑到这是儿童房，任何温度传感器的失效都可能导致过热或过冷伤害，或者掩盖了真实的火灾/烟雾风险（虽然未直接报警，但温度传感器常作为辅助监测）。",
    "排除误报：虽然 16:10 有入户门解锁和阳台门打开的动作，但这属于正常的家庭活动结束或外出准备，不能解释为何在 14:10-15:55 期间儿童房温度读数已经处于异常高位并持续变化。"

## 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": [
    "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": "日志显示为正常的家庭晚间活动模式，包括烹饪、人员移动和温度监测，未发现安全威胁或异常行为。",
  "reasoning": [
    "1. 烹饪活动分析：厨房灶具（kitchen_cook_surface）在三个时间段开启（06:39-07:29, 18:11-?, 19:01-?），且每次开启后不久灯光关闭或伴随其他正常活动。特别是傍晚时段（18:11和19:01）的连续开启符合晚餐准备的习惯。虽然日志中未明确记录灶具关闭时间（最后一条是19:01开启），但结合18:11后的温度数据波动及后续无烟雾报警，推测为正常烹饪过程，未检测到无人看管导致的火灾风险。",
    "2. 人员活动模式：主卧 occupancy 传感器全天大部分时间为占用状态（Occupancy=1），仅在凌晨00:00为0，符合住户作息。儿童房 occupancy 在17:23至18:43期间有间歇性触发，可能是孩子在房间内活动或传感器误报/灵敏度问题，但未发现长时间静止不动（跌倒风险）或完全无活动的异常情况。入口和客厅的运动传感器在傍晚时段频繁触发，符合家庭成员回家后的活动轨迹。",
    "3. 环境数据一致性：各房间温度传感器读数在合理范围内（约22.9°C - 23.5°C），数值变化平缓，无剧烈跳变表明传感器工作正常。没有漏水传感器、烟雾报警器或一氧化碳报警器的触发记录。",
    "4. 综合判断：所有事件均落在正常的生活节奏内，没有非法入侵迹象（门锁无异常操作记录，运动传感器与预期活动一致），也没有设备故障或危险状态的证据。"
  ],
  "key_evidence": [
    "kitchen_cook_surface 在 06:39, 18:11, 19:01 多次开启，配合 kitchen_light 开关，呈现典型的早餐和晚餐烹饪模式。",
    "master_bedroom_occupancy 在 00:00 为 0，其余时间多为 1，符合夜间睡眠、白天活动的规律。",
    "全时段无 smoke_co_alarm, water_leak_detector 报警，且温度数据稳定，排除火灾和水患风险。",
    "entrance_occupancy 和 living_room_occupancy 在 18:12 左右同时触发，符合家庭成员归家场景。"
  ],
  "recommended_actions": [
    "无需立即干预，系统运行正常。",
    "建议持续监控儿童房 occupancy 传感器的频率，若发现长期无变化或异常高频闪烁，可检查传感器是否被遮挡或需要校准。"
  ]
}
```

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

  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "正常样本是晚餐时间且有成人活动；异常样本发生在夜间儿童应睡时段。"
  ],
  "recommended_actions": [

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。
