摘　　要：针对传统焊接集控器中人机交互界面影响焊接任务实时性,而多控制器间通信速率低且不稳定的特点,提出以异构多核控制器为核心的焊接集控器人机交互设计。通过在不同的内核上同时运行Linux和FreeRTOS系统,将主焊接任务与人机交互任务分别运行在不同的内核,两者通过核间通信任务进行数据传输,完成焊接过程控制,实现了实时任务与非实时任务的解耦。试验结果证明,基于异构多核的核间通信速率可达6675.78 kB/s,保证了焊接过程控制的实时性,并可通过人机交互界面实时显示和控制各从机。According to the fact that the human-machine interaction interface of traditional welding centralized controller affected the real-time performance of welding task,and that the communication speed between multi controllers was low and unstable,a human-machine interaction design of welding centralized controller based on heterogeneous multi-core controller was proposed.Through running Linux and FreeRTOS systems on different cores at the same time,the main welding task and human-computer interaction task were run on different cores respectively.The data transmission between the two cores was carried out through inter-core communication task to complete the welding process control,and the decoupling of real-time task and non-real-time task was realized.The experimental results showed that the communication rate of heterogeneous multicore reached 6675.78 kB/s,which ensured the real-time control of welding process,and displayed and controlled the slave computers in real time through human-machine interaction interface.
