抱歉，我无法绘制流程图，但我可以为你描述一下代码的数据流程：

1. 用户点击按钮触发 pushButton_click() 方法，该方法会将用户输入的命令通过串口写入到设备中，并将命令显示在界面上；同时启动一个定时器 timer_send，定时器间隔为2秒，并启动一个定时器 timer_recive，定时器间隔为1秒。

2. 用户点击另一个按钮触发 pushButton_3_click() 方法，该方法会将用户输入的命令通过串口写入设备中，并将命令显示在界面上。

3. 定时器 timer_send 到达时间间隔后，会触发 data_write() 方法，该方法会将预定义的命令通过串口写入设备中，并将命令显示在界面上。

4. 定时器 timer_recive 到达时间间隔后，会触发 data_read() 方法，该方法会读取串口接收到的数据，并将数据显示在界面上。

5. 当定时器 timer_send 到达预设的命令数量时，会停止定时器 timer_send 的运行。

以下是根据代码绘制的发送数据流程图：

+---------------------+

          |
          V
+-----------------------------+
| self.ser.write(self.cmd[e]) |
+-----------------------------+
          |
          V
+------------------------------------------+
| self.plainTextEdit.appendPlainText(">>" + self.cmd[0]) |

          |
          V
+--------------------+
| self.ATnum = 0      |
| self.timer_send.start(2080) |
| self.timer_recive.start(1000) |
+--------------------+
          |
          V
+-----------------------------+
| self.ser.write(self.cmd[e]) |
+-----------------------------+
          |
          V
+------------------------------------------+

+------------------------------------------+
          |
          V
+---------------------+
| self.ATnum += 1     |
| self.timer_send.start(2000) |
| self.timer_recive.start(1000) |
+---------------------+

说明：

1. 当 `pushButton_click()` 函数被调用时，会依次执行下列操作。

2. 发送数据，即将 `self.cmd[e]` 发送到串口。

3. 将发送的数据添加到 `plainTextEdit` 中进行显示，格式为 `">>" + self.cmd[0]`。

4. 将 `self.ATnum` 设置为 0。

5. 开始发送定时器，定时器周期为 2080ms。

6. 开始接收定时器，定时器周期为 1000ms。

7. 在定时器周期到达后，再次发送数据，即将 `self.cmd[e]` 发送到串口。

8. 将发送的数据添加到 `plainTextEdit` 中进行显示，格式为 `">>" + self.cmd[0]`。

9. 将 `self.ATnum` 自增 1。

10. 开始发送定时器，定时器周期为 2000ms。

11. 开始接收定时器，定时器周期为 1000ms。
