# XYParser64Demo / XYParser8Demo
|
||||||
|
|
||||||
|
业务流程 demo，可直接连你的设备模拟器验证：
|
||||||
|
|
||||||
|
- `XYParser64Demo`：TCP 接收 64 导数据，可额外打开一个串口发送 `TRAIN_0 / TRAIN_1`
|
||||||
|
- `XYParser8Demo`：串口接收 8 导数据
|
||||||
|
- `XYAlgorithmUdpServer`：算法 ZMQ 服务端，接收 demo 发来的算法输入并回包
|
||||||
|
- Welch/PSD 固定走 ZMQ：
|
||||||
|
- `Feed -> ConvertSampleFramesToAlgorithmData -> ZMQ 发给算法 -> 收算法 ZMQ 回包 -> FeedAlgorithmData -> ReadWelch`
|
||||||
|
- demo 会打印 ZMQ 发送/接收包数、字节数，以及回包长度校验结果，方便看数据完整性
|
||||||
|
|
||||||
|
## 算法 ZMQ 服务端
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
.\x64\Debug\XYAlgorithmUdpServer.exe
|
||||||
|
```
|
||||||
|
|
||||||
|
默认：
|
||||||
|
|
||||||
|
- 绑定 `tcp://127.0.0.1:8100`
|
||||||
|
- 固定接收 `XYPARSER_FRAME_ALGORITHM_VALUE_COUNT * sizeof(double)` 字节
|
||||||
|
- 默认 `preprocess` 模式：按通道做去直流、50Hz 陷波、低通和平幅裁剪后回包
|
||||||
|
- 默认采样率 `250Hz`
|
||||||
|
- 默认高通 `0.5Hz`
|
||||||
|
- 默认低通 `45Hz`
|
||||||
|
- 默认工频陷波 `50Hz`
|
||||||
|
- 默认裁剪幅值 `5000uV`
|
||||||
|
- 可用 `echo` 模式：原样回包给发送方
|
||||||
|
- 可用 `zero` 模式：回全 0 的同长度 double 数组
|
||||||
|
|
||||||
|
常用覆盖参数：
|
||||||
|
|
||||||
|
- `--listen-host 127.0.0.1`
|
||||||
|
- `--listen-port 8100`
|
||||||
|
- `--receive-timeout-ms 1000`
|
||||||
|
- `--sample-rate 250`
|
||||||
|
- `--high-pass-hz 0.5`
|
||||||
|
- `--low-pass-hz 45`
|
||||||
|
- `--notch-hz 50`
|
||||||
|
- `--notch-q 30`
|
||||||
|
- `--clip-uv 5000`
|
||||||
|
- `--mode preprocess`
|
||||||
|
|
||||||
|
联调顺序：
|
||||||
|
|
||||||
|
- 先启动 `XYAlgorithmUdpServer`
|
||||||
|
- 再启动 `XYParser64Demo` 或 `XYParser8Demo`
|
||||||
|
- 如果 demo 端 `rxPackets` 开始增长，说明 ZMQ 链路已打通
|
||||||
|
|
||||||
|
## 64 导示例
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
.\x64\Debug\XYParser64Demo.exe
|
||||||
|
```
|
||||||
|
|
||||||
|
流程：
|
||||||
|
|
||||||
|
- 连接 64 导 TCP 设备
|
||||||
|
- 启动后直接开启 Welch/PSD，不打开阻抗
|
||||||
|
- 采样率和增益使用内置默认值
|
||||||
|
- 默认 TCP 主机为 `127.0.0.1`
|
||||||
|
- 默认 TCP 端口为 `5086`
|
||||||
|
- 默认 trigger 串口为 `COM44`
|
||||||
|
- demo 作为 ZMQ client 连接算法服务端 `tcp://127.0.0.1:8100`
|
||||||
|
- 按 `train-duration-ms` 周期循环交替发送 `TRAIN_0 / TRAIN_1`
|
||||||
|
|
||||||
|
常用覆盖参数：
|
||||||
|
|
||||||
|
- `--tcp-port 5086`
|
||||||
|
- `--trigger-com COM44`
|
||||||
|
- `--algorithm-host 127.0.0.1`
|
||||||
|
- `--algorithm-port 8100`
|
||||||
|
- `--train-duration-ms 3000`
|
||||||
|
|
||||||
|
## 8 导示例
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
.\x64\Debug\XYParser8Demo.exe
|
||||||
|
```
|
||||||
|
|
||||||
|
默认：
|
||||||
|
|
||||||
|
- 8 导数据串口为 `COM44`
|
||||||
|
- 串口波特率为 `460800`
|
||||||
|
- 算法 ZMQ 地址为 `tcp://127.0.0.1:8100`
|
||||||
|
- 启动后先发送一次 8 导阻抗开启命令
|
||||||
|
- 在阻抗模式下持续约 `60` 秒并打印阻抗结果
|
||||||
|
- 之后自动发送阻抗关闭命令，再恢复 Welch/PSD 和算法链路
|
||||||
|
|
||||||
|
8 导转 64 导的流程：
|
||||||
|
|
||||||
|
- 先解析成 8 导 `XYParserFrameSummary`
|
||||||
|
- 再通过 `XYParser_Convert8ChFramesTo64Ch` 扩展成 64 导
|
||||||
|
- 8 个已知导联按固定位置写入 64 导 summary
|
||||||
|
- 其余未覆盖的 56 个 64 导导联全部补 `0`
|
||||||
|
|
||||||
|
8 导到 64 导导联映射图：
|
||||||
|
|
||||||
|
```text
|
||||||
|
8ch[0] -> PO5
|
||||||
|
8ch[1] -> POZ
|
||||||
|
8ch[2] -> PO6
|
||||||
|
8ch[3] -> PO7
|

|
8ch[4] -> O1
|
||||||
|
8ch[5] -> OZ
|
||||||
|
8ch[6] -> O2
|
||||||
|
8ch[7] -> PO8
|
||||||
|
others -> 0
|
||||||
|
```
|
||||||
|
|
||||||
|
表格形式：
|
||||||
|
|
||||||
|
| 8导索引 | 64导导联 |
|
||||||
|
| --- | --- |
|
||||||
|
| 0 | PO5 |
|
||||||
|
| 1 | POZ |
|
||||||
|
| 2 | PO6 |
|
||||||
|
| 3 | PO7 |
|
||||||
|
| 4 | O1 |
|

|
||||||
|
| 6 | O2 |
|
||||||
|
| 7 | PO8 |
|
||||||
|
|
||||||
|
代码依据：
|
||||||
|
|
||||||
|
- 8 导映射表定义在 `k8ChLeadMap`
|
||||||
|
- 转换实现为 `XYParser_Convert8ChFramesTo64Ch -> Convert8ChSummaryTo64ChSummary`
|
||||||
|
|
||||||
|
常用覆盖参数：
|
||||||
|
|
||||||
|
- `--data-com COM44`
|
||||||
|
- `--baud 460800`
|
||||||
|
- `--bypass-checksum 1`
|
||||||
|
- `--algorithm-host 127.0.0.1`
|
||||||
|
- `--algorithm-port 8100`
|
||||||
|
- `--algorithm-timeout-ms 200`
|
||||||
|
- `--vref 4.5`

## 1. 参与角色
|
## 接口时序图
|
||||||
|
|
||||||
- **64导EEG采集设备**
|
|
||||||
- 持续输出原始 EEG 字节流。
|
|
||||||
- **上位机**
|
|
||||||
- 负责接收设备数据、调用 XYParser 库、对接算法模块。
|
|
||||||
- **XYParser 库**
|
|
||||||
- 负责帧解析、阻抗计算、算法数据回灌后的 Welch/PSD 计算。
|
|
||||||
- **算法**
|
|
||||||
- 接收上位机送入的算法数据，并输出用于 PSD/Welch 计算的数据。
|
|
||||||
|
|
||||||
## 2. 总体链路
|
|
||||||
|
|
||||||
当前流程可以分为两个阶段：
|
|
||||||
|
|
||||||
- **阶段一：阻抗检测阶段**
|
|
||||||
- 设备连接后，首先下发采样率和增益配置命令。
|
|
||||||
- 然后下发阻抗开启命令。
|
|
||||||
- 在该阶段持续接收设备数据，并通过 `XYParser_ReadImpedance` 读取阻抗结果。
|
|
||||||
- 阻抗检测结束后，下发阻抗关闭命令。
|
|
||||||
|
|
||||||
- **阶段二：常规采集与算法阶段**
|
|
||||||
- 基于 `XYParser_Feed` 解析得到的帧数据继续做常规采集。
|
|
||||||
- 帧数据先转换为算法数据，再送入算法模块。
|
|
||||||
- Welch/PSD 不再直接基于帧解析结果计算，而是基于算法数据，通过 `XYParser_FeedAlgorithmData` 输入后计算。

- 根据目标增益和采样率生成下发给 64 导设备的命令字节流。
|
|
||||||
- 上位机拿到该命令后发送给 EEG 设备，使设备端采样参数与库内配置保持一致。
|
|
||||||
- 当前推荐流程中：
|
|
||||||
- `vref` 固定为 `4.5`。
|
|
||||||
- 设备连接成功后，先下发 `250Hz + 增益6`。
|
|
||||||
- 开启阻抗前，下发 `250Hz + 增益24`，同时调用 `XYParser_SetImpedanceDetection(handle, 1)`，使库内 gain 自动切到 `24`。
|
|
||||||
- 关闭阻抗后，再下发 `250Hz + 增益6`，同时调用 `XYParser_SetImpedanceDetection(handle, 0)`，使库内 gain 自动恢复到 `6`。

|
||||||
|
-> algorithm_input_data
|
||||||
|
```
|
||||||
|
|
||||||
- `XYParser_Serialize8ChImpedanceCommand`
|
代码依据：
|
||||||
- 生成下发给 8 导设备的阻抗开关命令字节流。
|
|
||||||
- `open = 1` 表示开启阻抗检测，`open = 0` 表示关闭阻抗检测。
|
|
||||||
- 8 导流程中，设备连接后**不需要**额外下发增益和采样率命令。
|
|
||||||
|
|
||||||
### 4.2 原始数据解析
|
|
||||||
|
|
||||||
- `XYParser_Feed`
|
|
||||||
- 输入设备原始字节流。
|
|
||||||
- 输出解析后的 `XYParserFrameSummary` 数组。
|
|
||||||
- 该接口当前仍负责驱动阻抗相关计算。
|
|
||||||
- 该接口当前**不再驱动 Welch/PSD 计算**。
|
|
||||||
|
|
||||||
### 4.3 阻抗读取
|
|
||||||
|
|
||||||
- `XYParser_SetImpedanceDetection`
|
|
||||||
- 控制是否启用阻抗检测。
|
|
||||||
- 启用时，库内 ADC 增益自动切换到 `24`。
|
|
||||||
- 关闭时，库内 ADC 增益自动恢复到 `6`。
|
|
||||||
- 该接口只修改库内解析参数，不会自动给设备发送控制命令。
|
|
||||||
|
|
||||||
- `XYParser_ReadImpedance`
|
|
||||||
- 读取当前已经累计完成的阻抗结果。
|
|
||||||
- 阻抗结果来源于阻抗检测阶段的帧解析链路。
|
|
||||||
|
|
||||||
### 4.4 帧转算法数据
|
|
||||||
|
|
||||||
- `XYParser_ConvertSampleFramesToAlgorithmData`
|
|
||||||
- 将单帧 `XYParserFrameSummary` 转为算法需要的连续数组。
|
|
||||||
- 上位机通常在拿到帧数据后调用此接口，再把结果送入算法模块。
|
|
||||||
|
|
||||||
- `XYParser_Convert8ChFramesTo64Ch`
|
- `XYParser_Convert8ChFramesTo64Ch`
|
||||||
- 将 8 导帧转换为 64 导帧，未映射导联补 0。
|
- `Convert8ChSummaryTo64ChSummary`
|
||||||
- 8 导流程中，在送算法数据前，需要先把 8 导帧转换为 64 导帧，再调用 `XYParser_ConvertSampleFramesToAlgorithmData`。
|
- 8导映射表 `k8ChLeadMap`
|
||||||
|
|
||||||
### 4.5 算法数据回灌
|
|
||||||
|
|
||||||
- `XYParser_FeedAlgorithmData`
|
|
||||||
- 输入算法数据字节流。
|
|
||||||
- 内部先按采样缓存，再按每 5 个采样组装为一帧。
|
|
||||||
- 同时驱动 Welch/PSD 计算。
|
|
||||||
- 可选输出重新组装后的 `XYParserFrameSummary`。
|
|
||||||
|
|
||||||
- `XYParser_ResetAlgorithmDataCache`
|
|
||||||
- 清空算法数据缓存。
|
|
||||||
- 适合在切换任务、重置状态时调用。
|
|
||||||
|
|
||||||

|
|
||||||
- 将缓存中不足 5 个采样的尾数据补齐为 1 帧输出。
|
|
||||||
- 用于结束阶段处理残留数据。
|
|
||||||
|
|
||||||
### 4.6 Welch/PSD 读取

|
|
||||||
- 控制是否启用基于算法数据的 Welch 检测。
|
|
||||||
|
|
||||||
- `XYParser_ReadWelch`
|
|
||||||
- 读取当前已累计完成的 Welch/PSD 结果。
|
|
||||||
- Welch 结果当前仅来源于 `XYParser_FeedAlgorithmData`。
|
|
||||||
|
|
||||||
## 5. 当前设计结论
|
|
||||||
|
|
||||||
### 5.1 阻抗数据来源
|
|
||||||
|
|
||||||
- 阻抗在独立的阻抗检测阶段获取。
|
|
||||||
- 即：
|
|
||||||
- 设备连接成功
|
|
||||||
- 下发采样率250和增益6命令
|
|
||||||
- `XYParser_SetImpedanceDetection(handle, 1)`
|
|
||||||
- 下发采样率250和增益24命令
|
|
||||||
- 下发阻抗开启命令
|
|
||||||
- 设备原始字节流
|
|
||||||
- `XYParser_Feed`
|
|
||||||
- `XYParser_ReadImpedance`
|
|
||||||
- `XYParser_SetImpedanceDetection(handle, 0)`
|
|
||||||
- 下发阻抗关闭命令
|
|
||||||
- 下发采样率250和增益6命令
|
|
||||||
|
|
||||||
### 5.2 PSD 数据来源
|
|
||||||
|
|
||||||
- PSD/Welch 不再直接使用 `XYParser_Feed` 解析出来的帧数据。
|
|
||||||
- 当前流程为：
|
|
||||||
- 设备原始字节流
|
|
||||||
- `XYParser_Feed`
|
|
||||||
- `XYParser_ConvertSampleFramesToAlgorithmData`
|
|
||||||
- 算法处理
|
|
||||||
- `XYParser_FeedAlgorithmData`
|
|
||||||
- `XYParser_ReadWelch`
|
|
||||||
|
|
||||||
### 5.3 8导算法数据来源
|
|
||||||
|
|
||||||
- 8 导流程中，算法输入和 Welch/PSD 仍然按 64 导数据格式处理。
|
|
||||||
- 当前流程为：
|
|
||||||
- 8 导设备原始字节流
|
|
||||||
- `XYParser_Feed`
|
|
||||||
- `XYParser_Convert8ChFramesTo64Ch`
|
|
||||||
- `XYParser_ConvertSampleFramesToAlgorithmData`
|
|
||||||
- 算法处理
|
|
||||||
- `XYParser_FeedAlgorithmData`
