摘要
介绍了一个上位机为ＩＢＭ－ＰＣ／３８６、下位机为８０３１的全双工远距离分布控制系统的软件、硬件的构成和主要性能，并着重介绍了为提高可靠性和抗干扰性能所采取的软件和硬件措施。该系统可以做到１：２５０，实际运用证明了其可行性。
In this paper,the composition & main characteristics for the hardware & software of a remote full-duplex distributed control system with IBM-PC/386 upper miero-computer and Intel 8031 lower microprocessor are intro-duced,and the measures taken for the hardware and software with a view to enhancing the reliability and anti-interference performance of the system are emphatically introduced.1:250 can be realized by this system,the practicability of which having been proved by its being actually applied.
