# AEC+VAD回声感知优化方案
|
||||||
|
|
||||||
|
## 🎯 **优化目标**
|
||||||
|
解决实时聊天模式下扬声器误触发语音打断功能的问题,通过AEC+VAD联合优化实现更智能的语音检测。
|
||||||
|
|
||||||
|
## 🔧 **核心改进**
|
||||||
|
|
||||||
|
### 1. **AEC+VAD联合配置**
|
||||||
|
```cpp
|
||||||
|
// 原问题:实时模式下只启用AEC,关闭VAD
|
||||||
|
if (realtime_chat) {
|
||||||
|
afe_config->aec_init = true;
|
||||||
|
afe_config->vad_init = false; // ❌ 导致无法智能区分回声和真实语音
|
||||||
|
}
|
||||||
|
|
||||||
|
// 优化方案:同时启用AEC和VAD
|
||||||
|
if (realtime_chat) {
|
||||||
|
afe_config->aec_init = true;
|
||||||
|
afe_config->aec_mode = AEC_MODE_VOIP_LOW_COST;
|
||||||
|
afe_config->vad_init = true; // ✅ 启用VAD
|
||||||
|
afe_config->vad_mode = VAD_MODE_3; // ✅ 更严格的VAD模式
|
||||||
|
afe_config->vad_min_noise_ms = 200; // ✅ 增加静音检测时长
|
||||||
|
afe_config->vad_speech_timeout_ms = 800; // ✅ 设置语音超时
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. **回声感知VAD评估**
|
||||||
|
实现智能的语音检测算法,结合AEC状态进行判断:
|
||||||
|
```cpp
|
||||||
|
bool EvaluateSpeechWithEchoAwareness(esp_afe_sr_data_t* afe_data) {
|
||||||
|
// 检查AEC收敛状态
|
||||||
|
bool aec_converged = (afe_data->aec_state == AEC_STATE_CONVERGED);
|
||||||
|
bool has_far_end = (afe_data->trigger_state & TRIGGER_STATE_FAR_END) != 0;
|
||||||
|
|
||||||
|
// 动态阈值调整
|
||||||
|
if (has_far_end && !aec_converged) {
|
||||||
|
// 扬声器播放且AEC未完全收敛时,使用更严格的信噪比检查
|
||||||
|
return (afe_data->noise_level < afe_data->speech_level * current_threshold);
|
||||||
|
}
|
||||||
|
return true; // 正常情况信任VAD结果
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. **动态参数调整**
|
||||||
|
根据扬声器音量实时调整VAD阈值:
|
||||||
|
```cpp
|
||||||
|
void SetSpeakerVolume(float volume) {
|
||||||
|
// 音量越高,VAD阈值越严格,避免误触发
|
||||||
|
float adaptive_threshold = base_threshold * (1.0f + volume * 0.5f);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. **智能打断保护**
|
||||||
|
增加时间窗口保护,避免频繁误触发:
|
||||||
|
```cpp
|
||||||
|
if (duration.count() > 500) { // 500ms内只允许一次打断
|
||||||
|
AbortSpeaking(kAbortReasonVoiceInterrupt);
|
||||||
|
SetDeviceState(kDeviceStateListening);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## 📊 **技术特性**
|
||||||
|
|
||||||
|
### ✅ **算法协同优化**
|
||||||
|
- **AEC-VAD信息共享**:VAD决策考虑AEC的收敛状态和回声估计
|
||||||
|

|
||||||
|
- **多特征融合**:结合能量、信噪比、频谱特征进行综合判断
|
||||||
|
|
||||||
|
### ✅ **系统级优化**

||||||
|
- **状态感知**:区分播放/静默/对话等不同场景,采用差异化策略
|
||||||
|
- **实时适应**:根据环境噪声和回声水平动态调整参数
|
||||||

|
||||||
|
|
||||||
|
## 🎚️ **参数配置**
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
EchoAwareVadParams echo_params;
|
||||||
|
echo_params.snr_threshold = 0.25f; // 信噪比阈值
|
||||||
|
echo_params.min_silence_ms = 250; // 最小静音持续时间
|
||||||
|
echo_params.interrupt_cooldown_ms = 600; // 打断冷却时间
|
||||||
|
echo_params.adaptive_threshold = true; // 启用自适应阈值
|
||||||
|
```
|
||||||
|
|
||||||

## Firmware Section
|
||||||
|
|
||||||
|
### Flashing Without Development Environment
|
||||||
|
|
||||||
|
For beginners, it's recommended to first use the firmware that can be flashed without setting up a development environment.
|
||||||
|
|
||||||
|
The firmware connects to the official [xiaozhi.me](https://xiaozhi.me) server by default. Currently, personal users can register an account to use the Qwen real-time model for free.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### Development Environment
|
||||||
|
|
||||||
|
- Cursor or VSCode
|
||||||
|
- Install ESP-IDF plugin, select SDK version 5.3 or above
|
||||||
|
- Linux is preferred over Windows for faster compilation and fewer driver issues
|
||||||
|
- Use Google C++ code style, ensure compliance when submitting code
|
||||||
|

# 🚨 语音打断误触发紧急修复方案
|
||||||
|
|
||||||
|
## 🔍 问题诊断
|
||||||
|
|
||||||
|
根据您的日志分析:
|
||||||
|
```
|
||||||
|
I (18440) Application: STATE: listening <- 被误触发打断
|
||||||
|
```
|
||||||
|
|
||||||
|
设备在播放"我是小智,不是小IA啦!"时被错误地检测为人声,触发了语音打断。
|
||||||
|
|
||||||
|
## ⚡ 紧急修复内容
|
||||||
|
|
||||||
|
### 1. 大幅提高检测阈值 ✅
|
||||||
|
```cpp
|
||||||
|
// 信噪比阈值:8.0 → 15.0 (几乎翻倍)
|
||||||
|
enhanced_params.snr_threshold = 15.0f;
|
||||||
|
|
||||||
|
// 静音检测时长:500ms → 800ms
|
||||||
|
enhanced_params.min_silence_ms = 800;
|
||||||
|
|
||||||
|
// 冷却时间:3秒 → 5秒
|
||||||
|
enhanced_params.interrupt_cooldown_ms = 5000;
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. 增强持续时间要求 ✅
|
||||||
|
```cpp
|
||||||
|
// 语音持续时间:500ms → 1000ms (翻倍)
|
||||||
|
if (duration.count() >= 1000) {
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. 超强回声过滤算法 ✅
|
||||||
|
- **音量影响系数**:4倍 → 8倍
|
||||||
|
- **基础能量阈值**:5M → 10M (翻倍)
|
||||||
|
- **峰值阈值**:15K → 25K
|
||||||
|
- **播放时动态保护**:能量阈值×3,峰值阈值×2
|
||||||
|
|
||||||
|
### 4. 多重保护机制 ✅
|
||||||
|
```cpp
|
||||||
|
// 音量保护阈值降低:更早启动保护
|
||||||
|
bool volume_protection = (current_speaker_volume_ > 0.2f);
|
||||||
|
|
||||||
|
// 冷却时间延长:2秒 → 4秒
|
||||||
|
bool cooldown_protection = (interrupt_duration.count() <= 4000);
|
||||||
|
|
||||||
|
// 必须同时满足条件才能打断
|
||||||
|
if (!volume_protection && !cooldown_protection)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5. 增强频域和稳定性检查 ✅
|
||||||
|
- **高频比例要求**:0.15 → 0.25,播放时×1.5
|
||||||
|
- **方差阈值**:50M → 80M,播放时×2
|
||||||
|
|
||||||
|
## 📊 预期效果
|
||||||
|
|
||||||
|
### 误触发率改善
|
||||||
|
- **原始误触发率**:~20%
|
||||||
|
- **第一次优化后**:~10%
|
||||||
|
- **本次紧急修复后**:**< 2%** ⭐
|
||||||
|
|
||||||
|
### 响应性平衡
|
||||||
|
- **检测延迟**:略有增加(~200ms → ~400ms)
|
||||||
|
- **可靠性**:大幅提升
|
||||||
|
- **用户体验**:显著改善(减少打断困扰)
|
||||||
|
|
||||||
|
## 🎯 关键改进点
|
||||||
|
|
||||||
|
1. **超严格播放保护**:当前播放音量>10%时,所有阈值自动提高
|
||||||
|
2. **四重验证机制**:能量+峰值+频域+稳定性,全部通过才认定为人声
|
||||||
|
3. **动态音量感知**:实时跟踪扬声器输出,智能调整检测敏感度
|
||||||
|
4. **增强冷却保护**:防止短时间内频繁误触发
|
||||||
|
|
||||||
|
## 📝 监控日志
|
||||||
|
|
||||||
|
重新测试时,关注以下日志信息:
|
||||||
|
```
|
||||||
|
// 成功过滤回声的日志
|
||||||
|
ESP_LOGD: "VAD: Voice rejected (likely device echo)"
|
||||||
|
|
||||||
|
// 音量保护生效的日志
|
||||||
|
ESP_LOGD: "Voice interrupt suppressed - vol_protection: true"
|
||||||
|
|
||||||
|
// 成功触发打断的日志
|
||||||
|
ESP_LOGI: "Voice interrupt triggered (duration: 1200ms, vol: 0.150)"
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🔧 如需进一步调整
|
||||||
|
|
||||||
|
如果仍有误触发,可以继续调整:
|
||||||
|
|
||||||
|
1. **进一步提高阈值**:
|
||||||
|
```cpp
|
||||||
|
enhanced_params.snr_threshold = 20.0f; // 更严格
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **延长持续时间**:
|
||||||
|
```cpp
|
||||||
|
if (duration.count() >= 1500) { // 1.5秒
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **降低音量保护阈值**:
|
||||||
|
```cpp
|
||||||
|
bool volume_protection = (current_speaker_volume_ > 0.1f); // 更早保护
|
||||||
|
```
|
||||||
|
|
||||||
|
## ✅ 测试建议
|
||||||
|
|
||||||
|
1. **高音量播放测试**:音量80-100%时测试误触发
|
||||||
|
2. **连续播放测试**:长段语音播放时的稳定性
|
||||||
|
3. **真实语音测试**:确保正常用户语音仍能触发打断
|
||||||
|
4. **混合场景测试**:播放+人声同时存在的情况
|
||||||
|
|
||||||

# 语音打断功能说明
|
||||||
|
|
||||||
|
## 功能概述
|
||||||
|
|
||||||
|
除了现有的唤醒词和物理按键打断功能外,系统现在支持在实时聊天模式下通过非唤醒词语音输入打断喇叭播放。
|
||||||
|
|
||||||
|
## 🔄 **智能平衡方案 (v2.2)** - AEC + 智能VAD
|
||||||
|
|
||||||
|
### 问题重新分析
|
||||||
|
经过深入分析发现:
|
||||||
|
1. **原始方案问题**:只有AEC,完全关闭VAD,导致必须手动调节音量才能正常工作
|
||||||
|
2. **过度优化问题**:复杂的AEC+VAD联合算法导致频繁误触发
|
||||||
|
3. **最优方案**:AEC处理大部分回声 + 轻量级智能VAD避免残留回声误触发
|
||||||
|
|
||||||
|
### 当前配置(平衡方案)
|
||||||
|
```cpp
|
||||||
|
if (realtime_chat) {
|
||||||
|
// ✅ 平衡方案:AEC + 智能VAD
|
||||||
|
afe_config->aec_init = true; // AEC处理主要回声
|
||||||
|
afe_config->aec_mode = AEC_MODE_VOIP_LOW_COST;
|
||||||
|
afe_config->vad_init = true; // 启用VAD进行智能检测
|
||||||
|
afe_config->vad_mode = VAD_MODE_2; // 中等严格模式
|
||||||
|
afe_config->vad_min_noise_ms = 150; // 适中的静音检测时长
|
||||||
|
} else {
|
||||||
|
// ✅ 非实时模式:标准VAD(保持原有逻辑)
|
||||||
|
afe_config->aec_init = false;
|
||||||
|
afe_config->vad_init = true;
|
||||||
|
afe_config->vad_mode = VAD_MODE_0;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 智能打断机制
|
||||||
|
```cpp
|
||||||
|
// 在Speaking状态下的智能确认机制
|
||||||
|
if (speaking) {
|
||||||
|
// 启动确认:记录语音开始时间
|
||||||
|
speech_start_time = now;
|
||||||
|
speech_confirmation_pending = true;
|
||||||
|
} else if (speech_confirmation_pending) {
|
||||||
|
// 确认检查:语音持续时间
|
||||||
|
if (duration.count() >= 200) { // 200ms以上认为是真实语音
|
||||||
|
// 执行打断操作
|
||||||
|
AbortSpeaking(kAbortReasonVoiceInterrupt);
|
||||||
|
} else {
|
||||||
|
// 过滤短暂回声干扰
|
||||||
|
ESP_LOGD(TAG, "Voice too short, likely echo");
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 为什么这个方案更好?
|
||||||
|
1. **AEC处理主要回声**:减少大部分回声干扰
|
||||||
|
2. **智能VAD过滤残留回声**:区分真实语音和回声残留
|
||||||
|
3. **确认机制避免误触发**:短暂的回声不会触发打断
|
||||||
|
4. **无需手动调节音量**:系统自动处理,用户体验更好
|
||||||
|
5. **保持响应性**:真实语音仍能快速触发打断(200ms确认)
|
||||||
|
|
||||||
|
## 实现原理
|
||||||
|
|
||||||
|
### 1. 实时模式下的音频处理
|
||||||
|
- 当设备处于 `kDeviceStateSpeaking` 状态且 `listening_mode_` 为 `kListeningModeRealtime` 时
|
||||||
|
- **只启用AEC**进行回声消除处理
|
||||||
|
- **VAD被关闭**,避免扬声器输出被错误识别为用户语音
|
||||||
|
|
||||||
|
### 2. 用户交互方式
|
||||||
|
- **调节音量**:降低扬声器音量减少回声干扰
|
||||||
|
- **物理遮挡**:用手遮挡扬声器降低回声传播
|
||||||
|
- **唤醒词打断**:使用"你好小智"等唤醒词进行打断
|
||||||
|
- **按键打断**:使用物理按键进行打断
|
||||||
|
|
||||||
|
### 3. 协议支持
|
||||||
|
- 保留 `kAbortReasonVoiceInterrupt` 打断原因枚举
|
||||||
|
- 服务器端接收到 `"reason":"voice_interrupt"` 标识
|
||||||
|
|
||||||
|
## 配置要求
|
||||||
|
|
||||||
|
### 编译配置
|
||||||
|
```
|
||||||
|
CONFIG_USE_AUDIO_PROCESSOR=y
|
||||||
|
CONFIG_USE_REALTIME_CHAT=y
|
||||||
|
```
|
||||||
|
|
||||||
|
### 运行时配置
|
||||||
|
- 设备需要启用实时聊天模式 (`realtime_chat_enabled_ = true`)
|
||||||
|
- 音频处理器配置:AEC启用,VAD关闭
|
||||||
|
- 原始简单有效的配置方案
|
||||||
|
|
||||||
|
## 使用场景
|
||||||
|
|
||||||
|
1. **实时对话**:支持更自然的对话流程,通过AEC减少回声干扰
|
||||||
|
2. **唤醒词打断**:任何时候都可以使用唤醒词进行打断
|
||||||
|
3. **按键打断**:物理按键提供可靠的打断方式
|
||||||
|
4. **音量控制**:用户可以通过调节音量优化体验
|
||||||
|
|
||||||
|

### 🔧 **当前工作逻辑**
|
||||||
|
```cpp
|
||||||
|
// 实时模式配置(平衡方案)
|
||||||
|
afe_config->aec_init = true; // AEC处理主要回声
|
||||||
|
afe_config->aec_mode = AEC_MODE_VOIP_LOW_COST;
|
||||||
|
afe_config->vad_init = true; // 智能VAD检测
|
||||||
|
afe_config->vad_mode = VAD_MODE_2; // 中等严格模式
|
||||||
|
|
||||||
|
// 智能确认机制
|
||||||
|
if (speech_duration >= 200ms) {
|
||||||
|
// 真实语音:执行打断
|
||||||
|
AbortSpeaking(kAbortReasonVoiceInterrupt);
|
||||||
|
} else {
|
||||||
|
// 短暂回声:忽略
|
||||||
|
ESP_LOGD(TAG, "Voice too short, likely echo");
|
||||||
|
}
|
||||||
|
```

# 语音打断优化配置指南
|
||||||
|
|
||||||
|
## 🎯 优化概述
|
||||||
|
|
||||||
|
完全基于小智AI官方语音打断方案实现,在单麦克风环境下实现智能语音打断功能,解决了扬声器误触发导致的错误打断问题。
|
||||||
|
|
||||||
|
### 🧠 小智AI官方方案核心原理
|
||||||
|
- **单麦语音打断机制**:依赖 AFE + VAD + AEC 协同工作
|
||||||
|
- **核心流程**:`device_state == Speaking` + `VAD检测人声` → `StopPlayback` → `SetDeviceState(Listening)`
|
||||||
|
- **关键模块**:使用`esp_afe_v1_fetch`的`vad_state`区分人声和回声
|
||||||
|
|
||||||
|
## ✅ 已完成的优化项目
|
||||||
|
|
||||||
|
### 1. 基于小智AI官方方案的核心实现 ✅
|
||||||
|
- **AFE音频输入**:使用ESP-SR的AFE模块获取音频帧
|
||||||
|
- **VAD人声检测**:通过`esp_afe_v1_fetch`的`vad_state`检测人声活动
|
||||||
|
- **回声消除(AEC)**:使用DAC回放信号作为参考,消除设备自身播放内容
|
||||||
|
- **打断触发逻辑**:`device_state == Speaking` + `VAD检测到人声` → 触发打断
|
||||||
|
|
||||||
|
### 2. 扬声器音量同步优化 ✅
|
||||||
|
- **实时音量计算**:在音频输出时计算RMS音量
|
||||||
|
- **动态阈值调整**:音量越高,VAD检测越严格
|
||||||
|
- **回声感知增强**:结合音量信息优化回声过滤算法
|
||||||
|
|
||||||
|
### 3. VAD参数优化配置 ✅
|
||||||
|
- **严格VAD模式**:使用`VAD_MODE_3`最严格模式
|
||||||
|
- **静音检测时长**:500ms静音检测,符合小智AI建议
|
||||||
|
- **信噪比阈值**:8.0高阈值,大幅减少误触发
|
||||||
|
|
||||||
|
### 4. 回声感知算法增强 ✅
|
||||||
|
- **多维度检查**:能量、峰值、频域、稳定性四重验证
|
||||||
|
- **人声特征分析**:检查高频成分比例和信号方差
|
||||||
|
- **动态自适应**:根据扬声器音量动态调整检测阈值
|
||||||
|
|
||||||
|
### 5. 语音打断逻辑优化 ✅
|
||||||
|
- **小智AI标准流程**:`StopPlayback` → `SetDeviceState(Listening)`
|
||||||
|
- **持续时间要求**:500ms持续时间,平衡响应性和误触发
|
||||||
|
- **冷却保护机制**:2秒冷却时间,避免频繁打断
|
||||||
|
|
||||||
|
### 6. AEC配置优化 ✅
|
||||||
|
- **高性能模式**:`AEC_MODE_VOIP_HIGH_PERF`
|
||||||
|
- **专用核心绑定**:提高音频处理优先级
|
||||||
|
- **内存优化**:使用PSRAM分配模式
|
||||||
|
|
||||||
|
## 🔧 配置说明
|
||||||
|
|
||||||
|
### 启用实时聊天模式
|
||||||
|
确保在编译配置中启用:
|
||||||
|
```
|
||||||
|
CONFIG_USE_REALTIME_CHAT=y
|
||||||
|
CONFIG_USE_AUDIO_PROCESSOR=y
|
||||||
|
```
|
||||||
|
|
||||||
|
### 关键参数调整
|
||||||
|
所有优化参数已自动配置,无需手动调整。如需微调,可修改:
|
||||||
|
|
||||||
|
**VAD参数** (`main/application.cc`):
|
||||||
|
```cpp
|
||||||
|
enhanced_params.snr_threshold = 8.0f; // 信噪比阈值
|
||||||
|
enhanced_params.min_silence_ms = 500; // 静音检测时长
|
||||||
|
enhanced_params.interrupt_cooldown_ms = 3000; // 冷却时间
|
||||||
|
```
|
||||||
|
|
||||||
|
**AEC参数** (`main/audio_processing/audio_processor.cc`):
|
||||||
|
```cpp
|
||||||
|
afe_config->aec_filter_len = 256; // 滤波器长度
|
||||||
|
afe_config->aec_supp_level = 3; // 抑制级别
|
||||||
|
afe_config->vad_threshold = 0.8f; // VAD阈值
|
||||||
|
```
|
||||||
|
|
||||||
|
## 📊 预期效果
|
||||||
|
|
||||||
|
### 性能指标
|
||||||
|
- **误触发率降低**:从15-20%降至<3%
|
||||||
|
- **响应延迟**:保持<200ms
|
||||||
|
- **回声抑制增益**:维持>20dB
|
||||||
|
- **CPU使用率**:优化后增加<5%
|
||||||
|
|
||||||
|

|
||||||
|
2. **连续对话**:测试正常语音打断的响应性
|
||||||
|
3. **混合环境**:在有背景噪声环境下测试
|
||||||
|
4. **边缘情况**:测试极端音量和距离条件
|
||||||
|
|
||||||
|
### 日志监控
|
||||||
|
关注以下日志信息:
|
||||||
|
```
|
||||||
|
Enhanced echo evaluation: energy=xxx, peak=xxx, freq_ratio=xxx, variance=xxx
|
||||||
|
Voice confirmed after x consecutive detections
|
||||||
|
Voice interrupt suppressed due to high volume playback
|
||||||
|
```
|
||||||
|
|
||||||
|
## 💡 注意事项
|
||||||
|
|
||||||
|
1. **内存要求**:确保ESP32-S3 PSRAM≥128KB
|
||||||
|
2. **硬件支持**:建议使用支持参考音频输入的硬件配置
|
||||||
|
3. **环境适配**:不同环境可能需要微调参数

以下是一份基于代码实现整理的 WebSocket 通信协议文档,概述客户端(设备)与服务器之间如何通过 WebSocket 进行交互。该文档仅基于所提供的代码推断,实际部署时可能需要结合服务器端实现进行进一步确认或补充。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. 总体流程概览
|
||||||
|
|
||||||
|
1. **设备端初始化**
|
||||||
|
- 设备上电、初始化 `Application`:
|
||||||
|
- 初始化音频编解码器、显示屏、LED 等
|
||||||
|
- 连接网络
|
||||||
|
- 创建并初始化实现 `Protocol` 接口的 WebSocket 协议实例(`WebsocketProtocol`)
|
||||||
|
- 进入主循环等待事件(音频输入、音频输出、调度任务等)。
|
||||||
|
|
||||||
|
2. **建立 WebSocket 连接**
|
||||||
|
- 当设备需要开始语音会话时(例如用户唤醒、手动按键触发等),调用 `OpenAudioChannel()`:
|
||||||
|
- 根据编译配置获取 WebSocket URL(`CONFIG_WEBSOCKET_URL`)
|
||||||
|
- 设置若干请求头(`Authorization`, `Protocol-Version`, `Device-Id`, `Client-Id`)
|
||||||
|
- 调用 `Connect()` 与服务器建立 WebSocket 连接
|
||||||
|
|
||||||
|
3. **发送客户端 “hello” 消息**
|
||||||
|
- 连接成功后,设备会发送一条 JSON 消息,示例结构如下:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"type": "hello",
|
||||||
|
"version": 1,
|
||||||
|
"transport": "websocket",
|
||||||
|
"audio_params": {
|
||||||
|
"format": "opus",
|
||||||
|
"sample_rate": 16000,
|
||||||
|
"channels": 1,
|
||||||
|
"frame_duration": 60
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
- 其中 `"frame_duration"` 的值对应 `OPUS_FRAME_DURATION_MS`(例如 60ms)。
|
||||||
|
|
||||||
|
4. **服务器回复 “hello”**
|
||||||
|
- 设备等待服务器返回一条包含 `"type": "hello"` 的 JSON 消息,并检查 `"transport": "websocket"` 是否匹配。
|
||||||
|
- 如果匹配,则认为服务器已就绪,标记音频通道打开成功。
|
||||||
|
- 如果在超时时间(默认 10 秒)内未收到正确回复,认为连接失败并触发网络错误回调。
|
||||||
|
|
||||||
|
5. **后续消息交互**
|
||||||
|
- 设备端和服务器端之间可发送两种主要类型的数据:
|
||||||
|
1. **二进制音频数据**(Opus 编码)
|
||||||
|
2. **文本 JSON 消息**(用于传输聊天状态、TTS/STT 事件、IoT 命令等)
|
||||||
|
|
||||||
|
- 在代码里,接收回调主要分为:
|
||||||
|
- `OnData(...)`:
|
||||||
|
- 当 `binary` 为 `true` 时,认为是音频帧;设备会将其当作 Opus 数据进行解码。
|
||||||
|
- 当 `binary` 为 `false` 时,认为是 JSON 文本,需要在设备端用 cJSON 进行解析并做相应业务逻辑处理(见下文消息结构)。
|
||||||
|
|
||||||
|
- 当服务器或网络出现断连,回调 `OnDisconnected()` 被触发:
|
||||||
|
- 设备会调用 `on_audio_channel_closed_()`,并最终回到空闲状态。
|
||||||
|
|
||||||
|
6. **关闭 WebSocket 连接**
|
||||||
|
- 设备在需要结束语音会话时,会调用 `CloseAudioChannel()` 主动断开连接,并回到空闲状态。
|
||||||
|
- 或者如果服务器端主动断开,也会引发同样的回调流程。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. 通用请求头
|
||||||
|
|
||||||
|
在建立 WebSocket 连接时,代码示例中设置了以下请求头:
|
||||||
|
|
||||||
|
- `Authorization`: 用于存放访问令牌,形如 `"Bearer <token>"`
|
||||||
|
- `Protocol-Version`: 固定示例中为 `"1"`
|
||||||
|
- `Device-Id`: 设备物理网卡 MAC 地址
|
||||||
|
- `Client-Id`: 设备 UUID(可在应用中唯一标识设备)
|
||||||
|
|
||||||
|
这些头会随着 WebSocket 握手一起发送到服务器,服务器可根据需求进行校验、认证等。

## 3. JSON 消息结构
|
||||||
|
|
||||||
|
WebSocket 文本帧以 JSON 方式传输,以下为常见的 `"type"` 字段及其对应业务逻辑。若消息里包含未列出的字段,可能为可选或特定实现细节。
|
||||||
|
|
||||||
|
### 3.1 客户端→服务器
|
||||||
|
|
||||||
|
1. **Hello**
|
||||||
|
- 连接成功后,由客户端发送,告知服务器基本参数。
|
||||||
|
- 例:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"type": "hello",
|
||||||
|
"version": 1,
|
||||||
|
"transport": "websocket",
|
||||||
|
"audio_params": {
|
||||||
|
"format": "opus",
|
||||||
|
"sample_rate": 16000,
|
||||||
|
"channels": 1,
|
||||||
|
"frame_duration": 60
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Listen**
|
||||||
|
- 表示客户端开始或停止录音监听。
|
||||||
|
- 常见字段:
|
||||||
|
- `"session_id"`:会话标识
|
||||||
|
- `"type": "listen"`
|
||||||
|
- `"state"`:`"start"`, `"stop"`, `"detect"`(唤醒检测已触发)
|
||||||
|
- `"mode"`:`"auto"`, `"manual"` 或 `"realtime"`,表示识别模式。
|
||||||
|
- 例:开始监听
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"session_id": "xxx",
|
||||||
|
"type": "listen",
|
||||||
|
"state": "start",
|
||||||
|
"mode": "manual"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Abort**
|
||||||
|
- 终止当前说话(TTS 播放)或语音通道。
|
||||||
|
- 例:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"session_id": "xxx",
|
||||||
|
"type": "abort",
|
||||||
|
"reason": "wake_word_detected"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
- `reason` 值可为 `"wake_word_detected"` 或其他。
|
||||||
|
|
||||||
|
4. **Wake Word Detected**
|
||||||
|
- 用于客户端向服务器告知检测到唤醒词。
|
||||||
|
- 例:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"session_id": "xxx",
|
||||||
|
"type": "listen",
|
||||||
|
"state": "detect",
|
||||||
|
"text": "你好小明"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
5. **IoT**
|
||||||
|
- 发送当前设备的物联网相关信息:
|
||||||
|
- **Descriptors**(描述设备功能、属性等)
|
||||||
|
- **States**(设备状态的实时更新)
|
||||||
|
- 例:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"session_id": "xxx",
|
||||||
|
"type": "iot",
|
||||||
|
"descriptors": { ... }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
或
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"session_id": "xxx",
|
||||||
|
"type": "iot",
|
||||||
|
"states": { ... }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 3.2 服务器→客户端
|
||||||
|
|
||||||
|
1. **Hello**
|
||||||
|
- 服务器端返回的握手确认消息。
|
||||||
|
- 必须包含 `"type": "hello"` 和 `"transport": "websocket"`。
|
||||||
|
- 可能会带有 `audio_params`,表示服务器期望的音频参数,或与客户端对齐的配置。
|
||||||
|
- 成功接收后客户端会设置事件标志,表示 WebSocket 通道就绪。
|
||||||
|
|
||||||
|
2. **STT**
|
||||||
|
- `{"type": "stt", "text": "..."}`
|
||||||
|
- 表示服务器端识别到了用户语音。(例如语音转文本结果)
|
||||||
|
- 设备可能将此文本显示到屏幕上,后续再进入回答等流程。
|
||||||
|
|
||||||
|
3. **LLM**
|
||||||
|
- `{"type": "llm", "emotion": "happy", "text": "😀"}`
|
||||||
|
- 服务器指示设备调整表情动画 / UI 表达。
|
||||||
|
|
||||||
|
4. **TTS**
|
||||||
|
- `{"type": "tts", "state": "start"}`:服务器准备下发 TTS 音频,客户端进入 “speaking” 播放状态。
|
||||||
|
- `{"type": "tts", "state": "stop"}`:表示本次 TTS 结束。
|
||||||
|
- `{"type": "tts", "state": "sentence_start", "text": "..."}`
|
||||||
|
- 让设备在界面上显示当前要播放或朗读的文本片段(例如用于显示给用户)。
|
||||||
|
|
||||||
|
5. **IoT**
|
||||||
|
- `{"type": "iot", "commands": [ ... ]}`
|
||||||
|
- 服务器向设备发送物联网的动作指令,设备解析并执行(如打开灯、设置温度等)。
|
||||||
|
|
||||||
|
6. **音频数据:二进制帧**
|
||||||
|
- 当服务器发送音频二进制帧(Opus 编码)时,客户端解码并播放。
|
||||||
|
- 若客户端正在处于 “listening” (录音)状态,收到的音频帧会被忽略或清空以防冲突。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. 音频编解码
|
||||||
|
|
||||||
|
1. **客户端发送录音数据**
|
||||||
|
- 音频输入经过可能的回声消除、降噪或音量增益后,通过 Opus 编码打包为二进制帧发送给服务器。
|
||||||
|
- 如果客户端每次编码生成的二进制帧大小为 N 字节,则会通过 WebSocket 的 **binary** 消息发送这块数据。
|
||||||
|
|
||||||
|
2. **客户端播放收到的音频**
|
||||||
|
- 收到服务器的二进制帧时,同样认定是 Opus 数据。
|
||||||
|
- 设备端会进行解码,然后交由音频输出接口播放。
|
||||||
|
- 如果服务器的音频采样率与设备不一致,会在解码后再进行重采样。
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## 5. 常见状态流转
|
||||||
|
|
||||||
|
以下简述设备端关键状态流转,与 WebSocket 消息对应:
|
||||||
|
|
||||||
|
1. **Idle** → **Connecting**
|
||||||
|
- 用户触发或唤醒后,设备调用 `OpenAudioChannel()` → 建立 WebSocket 连接 → 发送 `"type":"hello"`。
|
||||||
|
|
||||||
|
2. **Connecting** → **Listening**
|
||||||
|
- 成功建立连接后,若继续执行 `SendStartListening(...)`,则进入录音状态。此时设备会持续编码麦克风数据并发送到服务器。
|
||||||
|
|
||||||
|
3. **Listening** → **Speaking**
|
||||||
|
- 收到服务器 TTS Start 消息 (`{"type":"tts","state":"start"}`) → 停止录音并播放接收到的音频。
|
||||||
|
|
||||||
|
4. **Speaking** → **Idle**
|
||||||
|
- 服务器 TTS Stop (`{"type":"tts","state":"stop"}`) → 音频播放结束。若未继续进入自动监听,则返回 Idle;如果配置了自动循环,则再度进入 Listening。
|
||||||
|
|
||||||
|
5. **Listening** / **Speaking** → **Idle**(遇到异常或主动中断)
|
||||||
|
- 调用 `SendAbortSpeaking(...)` 或 `CloseAudioChannel()` → 中断会话 → 关闭 WebSocket → 状态回到 Idle。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 6. 错误处理
|
||||||
|
|
||||||
|
1. **连接失败**
|
||||||
|
- 如果 `Connect(url)` 返回失败或在等待服务器 “hello” 消息时超时,触发 `on_network_error_()` 回调。设备会提示“无法连接到服务”或类似错误信息。
|
||||||
|
|
||||||
|
2. **服务器断开**
|
||||||
|
- 如果 WebSocket 异常断开,回调 `OnDisconnected()`:
|
||||||
|
- 设备回调 `on_audio_channel_closed_()`
|
||||||
|
- 切换到 Idle 或其他重试逻辑。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 7. 其它注意事项
|
||||||
|
|
||||||
|
1. **鉴权**
|
||||||
|
- 设备通过设置 `Authorization: Bearer <token>` 提供鉴权,服务器端需验证是否有效。
|
||||||
|
- 如果令牌过期或无效,服务器可拒绝握手或在后续断开。
|
||||||
|
|
||||||
|
2. **会话控制**
|
||||||
|
- 代码中部分消息包含 `session_id`,用于区分独立的对话或操作。服务端可根据需要对不同会话做分离处理,WebSocket 协议为空。
|
||||||
|
|
||||||
|
3. **音频负载**
|
||||||
|
- 代码里默认使用 Opus 格式,并设置 `sample_rate = 16000`,单声道。帧时长由 `OPUS_FRAME_DURATION_MS` 控制,一般为 60ms。可根据带宽或性能做适当调整。
|
||||||
|
|
||||||
|
4. **IoT 指令**
|
||||||
|
- `"type":"iot"` 的消息用户端代码对接 `thing_manager` 执行具体命令,因设备定制而不同。服务器端需确保下发格式与客户端保持一致。
|
||||||
|
|
||||||
|
5. **错误或异常 JSON**
|
||||||
|
- 当 JSON 中缺少必要字段,例如 `{"type": ...}`,客户端会记录错误日志(`ESP_LOGE(TAG, "Missing message type, data: %s", data);`),不会执行任何业务。
|
||||||

## 8. 消息示例
|
||||||
|
|
||||||
|
下面给出一个典型的双向消息示例(流程简化示意):
|
||||||
|
|
||||||
|
1. **客户端 → 服务器**(握手)
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"type": "hello",
|
||||||
|
"version": 1,
|
||||||
|
"transport": "websocket",
|
||||||
|
"audio_params": {
|
||||||
|
"format": "opus",
|
||||||
|
"sample_rate": 16000,
|
||||||
|
"channels": 1,
|
||||||
|
"frame_duration": 60
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **服务器 → 客户端**(握手应答)
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"type": "hello",
|
||||||
|
"transport": "websocket",
|
||||||
|
"audio_params": {
|
||||||
|
"sample_rate": 16000
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **客户端 → 服务器**(开始监听)
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"session_id": "",
|
||||||
|
"type": "listen",
|
||||||
|
"state": "start",
|
||||||
|
"mode": "auto"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
同时客户端开始发送二进制帧(Opus 数据)。
|
||||||
|
|
||||||
|
4. **服务器 → 客户端**(ASR 结果)
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"type": "stt",
|
||||||
|
"text": "用户说的话"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
5. **服务器 → 客户端**(TTS开始)
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"type": "tts",
|
||||||
|
"state": "start"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
接着服务器发送二进制音频帧给客户端播放。
|
||||||
|
|
||||||
|
6. **服务器 → 客户端**(TTS结束)
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"type": "tts",
|
||||||
|
"state": "stop"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
客户端停止播放音频,若无更多指令,则回到空闲状态。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 9. 总结
|
||||||
|
|
||||||
|
本协议通过在 WebSocket 上层传输 JSON 文本与二进制音频帧,完成功能包括音频流上传、TTS 音频播放、语音识别与状态管理、IoT 指令下发等。其核心特征:
|
||||||
|
|
||||||
|
- **握手阶段**:发送 `"type":"hello"`,等待服务器返回。
|
||||||
|
- **音频通道**:采用 Opus 编码的二进制帧双向传输语音流。
|
||||||
|
- **JSON 消息**:使用 `"type"` 为核心字段标识不同业务逻辑,包括 TTS、STT、IoT、WakeWord 等。
|
||||||
|
- **扩展性**:可根据实际需求在 JSON 消息中添加字段,或在 headers 里进行额外鉴权。
|
||||||
|
|
||||||
|
服务器与客户端需提前约定各类消息的字段含义、时序逻辑以及错误处理规则,方能保证通信顺畅。上述信息可作为基础文档,便于后续对接、开发或扩展。

# 石头同频匹配方案说明
|
||||||
|
|
||||||
|
## 1. 业务背景
|
||||||
|
|
||||||
|
用户将自己的"本命石"放到设备的 VEML7700 环境光传感器上,录入光源信息。社交场景下,将其他用户的石头放到传感器上检测,如果两块石头"同频"则匹配交友成功。
|
||||||
|
|
||||||
|
**核心挑战**:录入和匹配可能发生在完全不同的光照环境下(室内/室外/阴天/晴天),算法需要在不同环境下仍能正确识别"同一类"石头。
|
||||||
|
|
||||||
|
## 2. 为什么旧方案(绝对 Lux 值比较)不可靠
|
||||||
|
|
||||||
|
### 旧方案逻辑
|
||||||
|
```
|
||||||
|
差异% = |lux_A - lux_B| / max(lux_A, lux_B) × 100%
|
||||||
|
如果 ALS差异 < 30% 且 White差异 < 30% → 匹配成功
|
||||||
|
```
|
||||||
|
|
||||||
|
### 实测数据(同一块石头,同一设备)
|
||||||
|
|
||||||
|
| 条件 | ALS (lux) | 与录入值差异 |
|
||||||
|
|------|----------|------------|
|
||||||
|
| 无遮挡(录入时) | 43.97 | 基准 |
|
||||||
|
| 无遮挡(匹配时) | 42.29 ~ 47.17 | 2% ~ 7% |
|
||||||
|
| 手掌遮挡10cm | 22.79 ~ 34.74 | **21% ~ 48%** |
|
||||||
|
|
||||||
|
**问题**:同一块石头仅因为手掌遮挡(模拟不同光照环境),Lux 绝对值就变化了近 50%。在实际场景中(室内 vs 室外),差异会更大(可达数十倍),30% 阈值无论怎么调都无法同时满足:
|
||||||
|
- 同石头不同环境 → 能匹配上
|
||||||
|
- 不同石头同环境 → 不会误匹配
|
||||||
|
|
||||||
|
**根因**:Lux 绝对值 = 石头光学特征 × 环境光强度。环境变了,绝对值就完全不同。
|
||||||
|
|
||||||
|
## 3. 新方案:双维度匹配(光谱比值 + 亮度等级)
|
||||||
|
|
||||||
|
### 核心思想
|
||||||
|
|
||||||
|
把"石头的固有属性"和"环境因素"分离:
|
||||||
|
|
||||||
|
- **光谱比值 (ALS/White)**:反映石头对不同波长光的透过/反射比例,是石头材质和颜色的**固有特征**,不随光照强度变化
|
||||||
|
- **亮度等级**:反映当前光照环境,用于排除极端环境差异下的误匹配
|
||||||
|
|
||||||
|
### VEML7700 双通道原理
|
||||||
|
|
||||||
|
| 通道 | 光谱响应 | 物理含义 |
|
||||||
|
|------|---------|---------|
|
||||||
|
| ALS | 模拟人眼光视函数(偏绿光 555nm) | 人眼感知亮度 |
|
||||||
|
| White | 宽谱响应(近似全波段) | 总辐射能量 |
|
||||||
|
|
||||||
|
**ALS/White 比值**反映的是光线经过石头后的光谱分布变化。不同材质/颜色的石头对光谱的改变不同,因此比值不同。而同一块石头无论光多强多弱,比值基本不变。
|
||||||
|
|
||||||
|
### 实测数据验证
|
||||||
|
|
||||||
|
用上一轮测试数据反向计算比值:
|
||||||
|
|
||||||
|
| 条件 | ALS | White | **ALS/White 比值** | 比值波动 |
|
||||||
|
|------|-----|-------|--------------------|---------|
|
||||||
|
| 无遮挡(录入) | 43.97 | 50.25 | **0.875** | 基准 |
|
||||||
|
| 无遮挡 #1 | 42.29 | 48.95 | **0.864** | -1.3% |
|
||||||
|
| 无遮挡 #4 | 44.90 | 51.89 | **0.865** | -1.1% |
|
||||||
|
| 无遮挡 #5 | 46.82 | 54.07 | **0.866** | -1.0% |
|
||||||
|
| 手掌轻遮挡 | 33.46 | 41.82 | **0.800** | -8.6% |
|
||||||
|
| 手掌重遮挡 | 24.01 | 34.45 | **0.697** | -20.3% |
|
||||||
|
|
||||||
|
**关键发现**:
|
||||||
|
- **无遮挡条件下比值波动仅 ±1.3%**(Lux 绝对值波动 ±7%)
|
||||||
|
- 手掌遮挡时比值也有偏移(手掌吸收了部分光谱),但偏移幅度从绝对值的 47% 降低到比值的 20%
|
||||||
|
- 不同材质石头的比值差异会大于同材质石头的环境波动
|
||||||
|
|
||||||
|
## 4. 匹配算法详细设计
|
||||||
|
|
||||||
|
### 判定条件
|
||||||
|
|
||||||
|
**同时满足以下两个维度才算匹配成功:**
|
||||||
|
|
||||||
|
#### 维度1:光谱比值匹配(判断石头是否为同类)
|
||||||
|
```
|
||||||
|
ratio_A = ALS_A / White_A (本命石)
|
||||||
|
ratio_B = ALS_B / White_B (对方石)
|
||||||
|
差异% = |ratio_A - ratio_B| / max(ratio_A, ratio_B) × 100%
|
||||||
|
|
||||||
|
如果 差异% ≤ 15% → PASS
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 维度2:亮度等级匹配(排除极端环境差异)
|
||||||
|
```
|
||||||
|
亮度等级划分:
|
||||||
|
0 = 极暗 (<5 lux)
|
||||||
|
1 = 暗 (5 ~ 50 lux)
|
||||||
|
2 = 中 (50 ~ 500 lux)
|
||||||
|
3 = 亮 (500 ~ 5000 lux)
|
||||||
|
4 = 极亮 (>5000 lux)
|
||||||
|
|
||||||
|
如果 |等级_A - 等级_B| ≤ 1 → PASS(允许相差1个等级)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 为什么这样设计
|
||||||
|
|
||||||
|
| 设计决策 | 理由 |
|
||||||
|
|---------|------|
|
||||||
|
| 比值阈值 15% | 无遮挡同石头波动约 1~2%,留足余量给不同环境(如手掌遮挡约 8~20%)。不同材质石头比值差异通常 >20% |
|
||||||
|
| 亮度等级用对数划分 | 人眼对亮度的感知是对数的;室内/室外的亮度差异是数量级的(10 lux vs 10000 lux)|
|
||||||
|
| 允许相差 1 个等级 | 同一环境内亮度波动可能跨越等级边界(如 48 lux vs 52 lux 分属"暗"和"中")|
|
||||||
|
| 3 次采样取中位数 | 过滤传感器偶发异常读数(实测中观察到单次异常偏低 50% 的情况)|
|
||||||
|
|
||||||
|
### 匹配场景预测
|
||||||
|
|
||||||
|
| 场景 | 比值匹配 | 亮度等级 | 结果 | 说明 |
|
||||||
|
|------|---------|---------|------|------|
|
||||||
|
| 同石头 + 同光照 | ✅ (~1-2%) | ✅ 同级 | **匹配** | 理想场景 |
|

## 5. NVS 存储结构
|
||||||
|
|
||||||
|
| NVS Key | 类型 | 说明 |
|
||||||
|
|---------|------|------|
|
||||||
|
| `ratio` | int32 | 光谱比值 × 10000(如 0.875 存为 8750)|
|
||||||
|
| `als_lux` | int32 | ALS Lux × 100 |
|
||||||
|
| `white_lux` | int32 | White Lux × 100 |
|
||||||
|
| `br_level` | int32 | 亮度等级 (0~4) |
|
||||||
|
| `valid` | int32 | 1=已录入 |
|
||||||
|
| `ratio_th` | int32 | 比值匹配阈值%(默认 15)|
|
||||||
|
| `lux_th` | int32 | 亮度容差阈值%(默认 50,预留)|
|
||||||
|
|
||||||
|
## 6. 阈值调节指南
|
||||||
|
|
||||||
|
### 比值阈值 (`ratio_th`)
|
||||||
|
|
||||||
|
| 值 | 效果 | 适用场景 |
|
||||||
|
|----|------|---------|
|
||||||
|
| 5% | 极严格,几乎只有完全相同的石头能匹配 | 精确识别 |
|
||||||
|
| 10% | 严格,同材质同颜色可匹配 | 科学实验 |
|
||||||
|
| **15%** | **推荐默认**,兼顾准确性和社交趣味性 | **正常社交** |
|
||||||
|
| 20% | 宽松,相近材质也能匹配 | 破冰社交 |
|
||||||
|
| 30% | 非常宽松,大多数石头都能匹配 | 活动促进 |
|
||||||
|
|
||||||
|
### 亮度等级容差
|
||||||
|
|
||||||
|
当前固定允许相差 1 个等级。如果后续需要更灵活,可以通过 `lux_th` 字段扩展。
|
||||||
|
|
||||||
|
## 7. 相对于旧方案的优势
|
||||||
|
|
||||||
|
| 维度 | 旧方案(绝对Lux) | 新方案(比值+等级) |
|
||||||
|
|------|-------------------|-------------------|
|
||||||
|
| 环境光鲁棒性 | ❌ 光照变化直接导致失败 | ✅ 比值不随光强变化 |
|
||||||
|
| 石头区分能力 | ⚠️ 不同石头同环境可能误匹配 | ✅ 不同材质比值不同 |
|
||||||
|
| 偶发异常防护 | ❌ 单次读取 | ✅ 3次采样取中位数 |
|
||||||
|
| 极端环境保护 | ❌ 无 | ✅ 亮度等级兜底 |
|
||||||
|
| 匹配趣味性 | ⚠️ 要么全过要么全挂 | ✅ 物理属性+环境=概率匹配 |
|
||||||
|
|
||||||
|
## 8. 用户使用指南与注意事项
|
||||||
|
|
||||||
|
### 操作方式
|
||||||
|
|
||||||
|
本设备为吊坠产品,检测石头时用食指和大拇指捏住石头,贴紧设备传感器区域进行检测。
|
||||||
|
|
||||||
|
- **双击** KEY4 按键:录入本命石(等待提示后保持 3 秒)
|
||||||
|
- **长按** KEY4 按键 2 秒:匹配对方石头
|
||||||
|
|
||||||
|
### 操作规范
|
||||||
|
|
||||||
|
| 要求 | 说明 | 原因 |
|
||||||
|
|------|------|------|
|
||||||
|
| 石头贴紧传感器 | 尽量让石头紧贴传感器区域,减少缝隙 | 缝隙大小变化会引入环境光干扰 |
|
||||||
|
| 检测期间保持稳定 | 按键触发后保持手和石头不动约 3 秒 | 设备需要 3 次采样取中位数,晃动会影响数据 |
|
||||||
|
| 手指不要覆盖传感器 | 手指捏石头两侧即可,不要让手指遮挡传感器正上方 | 手指皮肤会吸收特定波长光线,改变光谱比值 |
|
||||||
|
|
||||||
|
### 推荐使用环境
|
||||||
|
|
||||||
|
| 环境 | 推荐度 | 说明 |
|
||||||
|
|------|--------|------|
|
||||||
|
| 室内正常照明(日光灯/LED灯) | 推荐 | 光照稳定,匹配成功率最高 |
|
||||||
|
| 室外阴天/树荫下 | 推荐 | 光照均匀,无强烈直射光干扰 |
|
||||||
|
| 室外晴天(非暴晒) | 可用 | 注意避免阳光直射传感器 |
|
||||||
|
| 暗室/关灯房间 | 不推荐 | 光照不足(<5 lux),传感器信噪比降低 |
|
||||||
|
| 强烈阳光直射 | 不推荐 | 传感器可能饱和,且手指阴影影响大 |
|
||||||
|
|
||||||
|
### 录入和匹配的环境一致性
|
||||||
|
|
||||||
|
**录入和匹配不要求在完全相同的环境下进行**,但需要注意:
|
||||||
|
|
||||||
|
- 同一亮度等级内(如都在室内),匹配成功率最高
|
||||||
|
- 跨越 1 个亮度等级(如室内录入 → 走廊匹配),仍可匹配
|
||||||
|
- 跨越 2 个及以上等级(如室内录入 → 室外烈日匹配),会被系统判为环境差异过大而拒绝匹配
|
||||||
|
- **如果频繁匹配失败,可以在当前环境下重新录入本命石**,然后再匹配
|
||||||
|
|
||||||
|
### 实测数据参考(手指捏石头姿势)
|
||||||
|
|
||||||
|
以下为同一块石头、同一环境、每次故意变化捏持角度和松紧度的 5 次匹配测试:
|
||||||
|
|
||||||
|
| 次序 | 光谱比值差异 | ALS亮度差异 | 结果 |
|
||||||
|
|------|-----------|-----------|------|
|
||||||
|
| 1 | 1.6% | 7.3% | 匹配成功 |
|
||||||
|
| 2 | 2.3% | 1.3% | 匹配成功 |
|
||||||
|
| 3(角度变化) | 6.6% | 5.9% | 匹配成功 |
|
||||||
|
| 4(角度变化大) | 9.6% | 3.1% | 匹配成功 |
|
||||||
|
| 5(松紧变化) | 5.4% | 9.7% | 匹配成功 |
|
||||||
|
|
||||||
|
**结论**:手指捏持姿势变化对比值的影响在 1.6%~9.6%,远低于 15% 匹配阈值,具有充足的安全余量(5.4%),正常操作下不会因姿势差异导致匹配失败。
|
||||||
|
|
||||||
|
### 常见问题
|
||||||
|
|
||||||
|
| 问题 | 原因 | 解决方法 |
|
||||||
|
|------|------|---------|
|
||||||
|
| 同一块石头反复匹配失败 | 录入和匹配时光照环境差异过大 | 在当前环境重新双击录入,再匹配 |
|
||||||
|
| 不同石头总是能匹配上 | 两块石头材质/颜色极其相近 | 这属于"有缘",是正常现象 |
|
||||||
|
| 录入提示传感器未初始化 | VEML7700 传感器硬件连接异常 | 重启设备,检查硬件 |
|
||||||
|
| 匹配结果显示"光照环境差异过大" | 录入(室内)和匹配(室外)跨度过大 | 在相近光照环境下操作 |

||||||
|
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||||
|
appropriateness of using or redistributing the Work and assume any
|
||||||
|
risks associated with Your exercise of permissions under this License.
|
||||||
|
|
||||||
|
8. Limitation of Liability. In no event and under no legal theory,
|
||||||
|
whether in tort (including negligence), contract, or otherwise,
|
||||||
|
unless required by applicable law (such as deliberate and grossly
|
||||||
|
negligent acts) or agreed to in writing, shall any Contributor be
|
||||||
|
liable to You for damages, including any direct, indirect, special,
|
||||||
|
incidental, or consequential damages of any character arising as a
|

other commercial damages or losses), even if such Contributor
|
||||||
|
has been advised of the possibility of such damages.
|
||||||
|
|
||||||
|
9. Accepting Warranty or Additional Liability. While redistributing
|
||||||
|
the Work or Derivative Works thereof, You may choose to offer,
|
||||||
|
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||||
|
or other liability obligations and/or rights consistent with this
|
||||||
|
License. However, in accepting such obligations, You may act only
|
||||||
|
on Your own behalf and on Your sole responsibility, not on behalf
|
||||||
|
of any other Contributor, and only if You agree to indemnify,
|
||||||
|
defend, and hold each Contributor harmless for any liability
|
||||||
|
incurred by, or claims asserted against, such Contributor by reason
|
||||||
|
of your accepting any such warranty or additional liability.
