本文讨论了远动装置的一般组成,分别对外设和对象接口进行了分析,运用Intel公司的OEM产品组成了微机运动中RTLT的硬件。在软件设计上引入iRMX86实时OS中多道任务并行运行的调度管理思想,把以前的单道控制软件分为多个任务,通过对多个任务的调度运行,实现系统的复杂控制。设计中把中断分为中断处理和中断服务两部分,前者只完成一些基本的中断响应处理,在中断服务中完成中断要完成的工作,把在中断中要做的工作转移到正常程序中完成,从而提高了系统的实时性。文章后半部分重点讨论了在步力系统全微机运动中的应用,该系统已于1987年通过鉴定,现已在某矿务局投入运行。并获得了较高的经济效益。
This article discusses the general components of the telecontrol device, respectively, peripherals and object interfaces were analyzed, the use of Intel’s OEM products constitute the hardware RTLT hardware movement. In the software design, iRMX86 real-time OS is introduced to manage the scheduling of multiple tasks in parallel. The former single-channel control software is divided into several tasks, and the complex control of the system is achieved through the scheduling operation of multiple tasks. The design interrupt is divided into interrupt handling and interrupt service two parts, the former only to complete some basic interrupt response processing interrupt service to complete the interrupt to be completed, the interrupt to be done in the transfer to the normal process to complete, Thus improving the real-time system. The second half of the article focuses on the application of the PC-based PCF system. The system was appraised in 1987 and is now put into operation at a mining bureau. And access to higher economic benefits.
