基于QT的嵌入式系统文件传输上位机软件设计

Software design of embedded system file transfer host computer based on QT

基于解决嵌入式设备远程文件传输的目的,采用QT编程技术设计了基于网络的嵌入式系统文件传输上位机软件。将MQTT通信协议和Ymodem文件传输机制相结合,借助QT官方库文件QTcpSocket、QtMqtt和QMqttClient以及自主实现Ymodem文件传输机制,实现了上位机的设计。该上位机可以在嵌入式设备处于较为复杂的环境时,以较小的网络传输代价,准确地完成唤醒和文件传输。通过上位机与嵌入式设备的联合调试可以得出,该上位机软件可以稳定完成文件的传输,并且可以长时间连续工作。

In order to solve the problem of remote file transmission of embedded devices,QT programming technology is used to design the host computer software of embedded system file transmission based on network.The host computer realizes the design of host computer by combining the MQTT communication protocol with the Ymodem file transmission mechanism,with the help of QT official library files QTcpSocket,QtMqtt and QMqttClient,as well as the independent implementation of Ymodem file transmission mechanism.The host computer can complete the wake⁃up and file transmission accurately with less network transmission cost in the case of complex embedded device environment.Through the joint debugging with embedded devices,the results show that the host computer software can stably complete the file transmission,and the host computer software can work stably and continuously.
