RT-Thread和Qt的可视化印花机控制系统设计

为了提高印花机控制系统的自动化水平,针对当前印花机控制系统功能单一、稳定性差、缺少直观的数据显示和命令操作界面等缺陷,提出一种基于上下位机模式的可视化印花机控制方案。该方案采用嵌入式实时操作系统RT-Thread实现下位机模块的任务调度,采用Qt应用程序框架设计上位机的人机交互图形界面,并通过CAN总线连接下位机进行印花电机的监控。实验证明,该方案不仅提高了系统的可靠性和操作的直观性,而且有利于系统的进一步改进与升级。

Visualized Embossing Machine Based on RT-Thread and Qt

As the currently control systems of the embossing machine suffer from single-function, poor stability, shortage of visualized data-displaying, command operation, and so on, the paper designs a visualized control scheme for the embossing machine to improve this situation and promotes the automation technology of the control system. This scheme uses the upper and lower machine collaborative model. The lower machine deals with RT-Thread RTOS, and the upper machine deals with the interaction between machines and humans through a GUI designed in the Qt application framework and monitors the embossing motor in the lower machine through CAN bus. The result of experiment shows that this scheme can increase the reliability and simple operation of the system, and makes a contri hution to the further improvement of the currently control systems of the embossing machine.
