Taking an example of dominant and subordinate system made up of PC and high-speed DSP board, the system configuration is introduced, and then the realization process of double buffer mechanism and multi-thread technique is expounded. At last the real-time display image is given out. 以PC机和高速数字信号处理板构成的主从式系统为例,简单介绍了系统的组成,详细阐述了双缓存机制和多线程技术的实现过程,最后给出了实时显示的图像效果。
The system not only makes use of module hardware and principal and subordinate system including industrial PC and independent design control board. 该系统采用工业PC机加自行开发的控制模板的模块式硬件体系和主从式结构。
The subordinate system monitors the process variables such as temperature, pressure, flow, liquid, level, switch status and so on. 下位机用于设备的开关控制、温度、压力、流量等过程量的监视和控制。
Together with the parameter setting of subordinate system, the software configuration of the superordinate computer and its functions are expounded. 详述了下位机参数设置、上位机组态软件的设置及功能。
The MCU control system is mainly used by system's auto run and the PC control system is a subordinate system that offers operation to do all movements. 单片机控制系统由信号的收发模块、信号处理模块、液晶显示模块组成,主要用于系统的自动运行。
