Abstract
This paper introduces a design AT89S52 single chip control with the core of munication control module design system, detailed instructions on the system of basic principle, hardware frame, main circuit and software frame. The whole system uses modular design, including between microcontroller and lower puter munication control circuit, and munication module with PC based on serial interface between the RS-232 standard munication interface circuit and USB high-munication interface circuit. munication control system through the PC's RS-232 munication and USB high-munications, thus through munication control module formation and lower puter connection, control, and a machine motion controller will receive data storage munication within the memory expansion.
This munication method is simple, remoting real-time control outside, still can be widely used in industrial supervisory control and data acquisition system. This system has reliable performance, strong anti-jamming capability, low power consumption, high performance-to-price advantages in munication domain, has important application value and good development prospect.
