# ECG十二导联信号生成系统 - 工作交接文档
|
||||
|
||||
## 项目概述
|
||||
|
||||
本项目是一个基于ESP32-S3的ECG（心电图）十二导联信号生成系统，能够同时生成并输出I、II、III导联以及V1-V6胸导联的ECG信号，通过DAC芯片输出到8个独立通道。
|
||||
|
||||
### 主要功能
|
||||
- **十二导联ECG信号生成**：I、II、III、V1-V6导联
|
||||
- **多通道DAC输出**：8个独立通道同时输出
|
||||
- **高精度波形生成**：20kHz采样率，支持10,000点查找表
|
||||
- **内存优化**：PSRAM存储，防止DRAM溢出
|
||||
- **实时信号处理**：50μs定时器中断
|
||||
|
||||

|
||||
|
||||
## 系统架构
|
||||
|
||||
### 硬件平台
|
||||
- **主控芯片**：ESP32-S3
|
||||
- **DAC芯片**：AD5328BRUZ（8通道12位DAC）
|
||||
- **通信接口**：SPI2（DAC控制）、I2C0（触摸屏）
|
||||
- **显示**：ST7789 LCD + FT5x06触摸屏

|
||||
#### 1.1 导联类型定义
|
||||
```c
|
||||
typedef enum {
|
||||
ECG_LEAD_I = 0, // I导联：右手到左手
|
||||
ECG_LEAD_II = 1, // II导联：右手到左腿
|
||||
ECG_LEAD_III = 2, // III导联：左手到左腿
|
||||
ECG_LEAD_V1 = 3, // V1导联：胸骨右缘第四肋间
|
||||
ECG_LEAD_V2 = 4, // V2导联
|
||||
ECG_LEAD_V3 = 5, // V3导联：过渡区
|
||||
ECG_LEAD_V4 = 6, // V4导联：高R波
|
||||
ECG_LEAD_V5 = 7, // V5导联
|
||||
ECG_LEAD_V6 = 8 // V6导联
|
||||
} ecg_lead_t;
|
||||
```
|
||||
|
||||
#### 1.2 ECG生成器结构体
|
||||
```c
|
||||
typedef struct {
|
||||
// 用户参数
|
||||
float heart_rate; // 心率 (次/分)
|
||||
float amplitude; // 幅值 (V)
|
||||
ecg_lead_t lead; // 当前导联
|
||||
|
||||
// 内部状态
|
||||
uint32_t sample_count; // 样本计数器
|
||||
float sample_rate; // 采样率 (Hz)
|
||||
bool is_running; // 运行状态
|
||||
|
||||
// 导联特定参数
|
||||
float p_amp_ratio; // P波幅度比例
|
||||
float q_amp_ratio; // Q波幅度比例
|
||||
float r_amp_ratio; // R波幅度比例
|
||||
float s_amp_ratio; // S波幅度比例
|
||||
float t_amp_ratio; // T波幅度比例
|
||||
bool p_bidirectional; // P波是否双向（V1导联特有）
|
||||
|
||||
// 查找表相关
|
||||
float* ecg_lookup_table; // ECG查找表
|
||||
uint32_t table_size; // 查找表大小
|
||||
uint32_t table_index; // 当前索引
|
||||
|
||||
// 按比例重复采样（防止相位失真）
|
||||
uint32_t ideal_table_size; // 理想表大小
|
||||
uint32_t samples_per_point; // 每个表点对应的样本数
|
||||
uint32_t sample_counter; // 当前表点的样本计数器
|
||||
} ecg_generator_t;
|
||||
```
|
||||
|
||||
#### 1.3 关键算法：按比例重复采样
|
||||
|
||||
**问题**：当理想表大小超过10,000点时，需要限制表大小防止内存溢出，但会导致相位失真。
|
||||
|
||||
**解决方案**：按比例重复采样
|
||||
```c
|
||||
// 计算理想表大小和实际表大小
|
||||
generator->ideal_table_size = (uint32_t)(generator->sample_rate / generator->frequency);
|
||||
const uint32_t MAX_TABLE_SIZE = 10000;
|
||||
generator->table_size = generator->ideal_table_size;
|
||||
if (generator->table_size > MAX_TABLE_SIZE) {
|
||||
generator->table_size = MAX_TABLE_SIZE;
|
||||
}
|
||||
|
||||
// 计算每个表点需要重复的样本数
|
||||
generator->samples_per_point = generator->ideal_table_size / generator->table_size;
|
||||
|
||||
// 在get_next_sample中实现重复采样
|
||||
if (generator->sample_counter >= generator->samples_per_point) {
|
||||
generator->sample_counter = 0;
|
||||
generator->table_index = (generator->table_index + 1) % generator->table_size;
|
||||
}
|
||||
```
|
||||
|
||||
#### 1.4 导联特定参数设置
|
||||
|
||||
每个导联都有独特的波形特征：
|
||||
|
||||
```c
|
||||
void ecg_generator_set_lead_parameters(ecg_generator_t *generator, ecg_lead_t lead) {
|
||||
switch (lead) {
|
||||
case ECG_LEAD_I:
|
||||
generator->p_amp_ratio = 0.12; // P波较小
|
||||
generator->q_amp_ratio = 0.25;
|
||||
generator->r_amp_ratio = 0.7; // R波中等
|
||||
generator->s_amp_ratio = 0.3;
|
||||
generator->t_amp_ratio = 0.3;
|
||||
generator->p_bidirectional = false;
|
||||
break;
|
||||
|
||||
case ECG_LEAD_V1:
|
||||
generator->p_amp_ratio = 0.08; // P波双向
|
||||
generator->q_amp_ratio = 0.0; // 无Q波
|
||||
generator->r_amp_ratio = 0.25; // 小r波
|
||||
generator->s_amp_ratio = 1.0; // 深S波
|
||||
generator->t_amp_ratio = -0.15; // T波倒置
|
||||
generator->p_bidirectional = true; // 双向P波
|
||||
break;
|
||||
|
||||
// ... 其他导联
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 1.5 双向P波实现（V1导联特有）
|
||||
|
||||
```c
|
||||
// 在波形计算中
|
||||
if (generator->p_bidirectional) {
|
||||
// 双向P波：先正后负
|
||||
float p_positive = p_amp * expf(-(t_norm - p_time_ratio) * (t_norm - p_time_ratio) /
|
||||
(2.0f * p_width_ratio * p_width_ratio));
|
||||
float p_negative = -p_amp * 0.6f * expf(-(t_norm - (p_time_ratio + 0.02f)) *
|
||||
(t_norm - (p_time_ratio + 0.02f)) /
|
||||
(2.0f * p_width_ratio * p_width_ratio));
|
||||
p = p_positive + p_negative;
|
||||
} else {
|
||||
// 单向P波
|
||||
p = p_amp * expf(-(t_norm - p_time_ratio) * (t_norm - p_time_ratio) /
|
||||
(2.0f * p_width_ratio * p_width_ratio));
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 十二导联系统封装
|
||||
|
||||
#### 2.1 系统初始化函数
|
||||
```c
|
||||
int ecg_generator_init_twelve_leads_system(float sample_rate, float amplitude, float heart_rate) {
|
||||
// 初始化所有9个导联生成器
|
||||
ecg_generator_init(&g_ecg_gen_i, sample_rate, ECG_LEAD_I);
|
||||
ecg_param_set(&g_ecg_gen_i, amplitude, heart_rate);
|
||||
ecg_generator_generate_lookup_table(&g_ecg_gen_i);
|
||||
ecg_generator_start(&g_ecg_gen_i);
|
||||
|
||||
// ... 重复其他8个导联
|
||||
|
||||
return 0; // 成功
|
||||
}
|
||||
```
|
||||
|
||||
#### 2.2 多通道输出函数
|
||||
```c
|
||||
void ecg_generator_output_twelve_leads(void (*set_channel_voltage)(uint8_t channel, float voltage)) {
|
||||
float voltage;
|
||||
|
||||
// 通道映射：0通道输出I导联，1通道输出II导联，2-7通道输出V1-V6导联
|
||||
voltage = ecg_generator_get_next_sample(&g_ecg_gen_i);
|
||||
set_channel_voltage(0, voltage); // 通道0：I导联
|
||||
|
||||
voltage = ecg_generator_get_next_sample(&g_ecg_gen_ii);
|
||||
set_channel_voltage(1, voltage); // 通道1：II导联
|
||||
|
||||
voltage = ecg_generator_get_next_sample(&g_ecg_gen_v1);
|
||||
set_channel_voltage(2, voltage); // 通道2：V1导联
|
||||
|
||||
// ... 其他通道
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 硬件驱动 (`esp32_s3_szp.c`)
|
||||
|
||||
#### 3.1 SPI初始化
|
||||
```c
|
||||
// SPI总线配置
|
||||
spi_bus_config_t bus_config = {
|
||||
.miso_io_num = GPIO_NUM_NC, // 不使用MISO
|
||||
.mosi_io_num = PIN_MOSI, // GPIO12
|
||||
.sclk_io_num = PIN_SCK, // GPIO13
|
||||
.quadhd_io_num = GPIO_NUM_NC,
|
||||
.quadwp_io_num = GPIO_NUM_NC,
|
||||
};
|
||||
|
||||
// SPI设备配置
|
||||
spi_device_interface_config_t dev_config = {
|
||||
.clock_speed_hz = 1000000, // 1 MHz
|
||||
.mode = 0, // SPI模式0
|
||||
.spics_io_num = PIN_CS, // GPIO10
|
||||
.queue_size = 1,
|
||||
.flags = SPI_DEVICE_HALFDUPLEX, // 半双工
|
||||
};
|
||||
```
|
||||
|
||||
#### 3.2 DAC数据发送
|
||||
```c
|
||||
void set_channel_voltage(uint8_t channel, float voltage) {
|
||||
// 电压转数字值（12位）
|
||||
uint16_t dac_value = (uint16_t)((voltage / V_REF) * 4095);
|
||||
|
||||
// 组装SPI数据包（16位）
|
||||
uint8_t tx_data[2] = {
|
||||
((channel & 0x07) << 4) | ((dac_value >> 8) & 0x0F), // 高字节
|
||||
(dac_value & 0xFF) // 低字节
|
||||
};
|
||||
|
||||
// SPI事务
|
||||
spi_transaction_t t = {
|
||||
.length = 16,
|
||||
.tx_buffer = tx_data,
|
||||
.rx_buffer = NULL
|
||||
};
|
||||
|
||||
esp_err_t ret = spi_device_transmit(handle, &t);
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 主程序 (`main.c`)
|
||||
|
||||
#### 4.1 系统初始化流程
|
||||
```c
|
||||
void app_main(void) {
|
||||
int led_count = 0;
|
||||
|
||||
// 1. 硬件初始化
|
||||
init_hardware(); // I2C、LED、DAC初始化
|
||||
|
||||
// 2. ECG系统初始化
|
||||
init_ecg_system(); // 初始化十二导联系统
|
||||
|
||||
// 3. 主循环
|
||||
while (true) {
|
||||
// LED状态指示
|
||||
gpio_set_level(LED_PIN, 1);
|
||||
vTaskDelay(pdMS_TO_TICKS(1000));
|
||||
gpio_set_level(LED_PIN, 0);
|
||||
vTaskDelay(pdMS_TO_TICKS(1000));
|
||||
|
||||
// 内存监控
|
||||
if (++led_count % 10 == 0) {
|
||||
displayMemoryUsage();
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 4.2 定时器中断处理
|
||||
```c
|
||||
static void signal_timer_callback(void* arg) {
|
||||
// ECG十二导联模式：使用十二导联输出函数
|
||||
ecg_generator_output_twelve_leads(set_channel_voltage);
|
||||
|
||||
signal_sample_count++;
|
||||
}
|
||||
```
|
||||
