专门用于多串口通讯程序，不同串口由不同的线程控制。

淘宝上花钱买的，CH340上位机驱动源码，可以集成自己软件里，开多一个线程来实时检测串口是否在线-Spend money on Taobao, CH340 host computer driver source code, can integrate their own software to open more than one thread are online real-time detection of serial

通过建立多个线程，利用串口进行数据的发送。通过使用Mutex控制串口的发送，使得同一时间只有一个线程利用串口发送数据。-By creating multiple threads, using serial data transmission. By using Mutex control the serial port to send, so that only one thread is using the serial port to send data.

能包括多线程记录,串口操作,日志记录,U盘自动拷贝,声音告警()
