Title Intelligent motor protection system —Display system design
Abstract
Based on the application of integrated circuits and single-chip microcomputer control, according to the performance characteristics of the electric motor, microcontroller technology, complete hardware circuit design of intelligent protector, and work out motor protection programs, finally complete the whole system design.This paper mainly through the scheme comparison, hardware design, software design, systematic anti-interference describe motor module design principle of intelligent protector, design process and motor of intelligent protector, mainly USES part is the intelligent protector display system and the design of hardware and software of the control system and the display system of serial communication between. Its display section consists mainly of AT89C2051 microcontroller to achieve.Due to the microcomputer application system in different circumstances work, have different interference invaded, also can have different stability requirement. Its software and hardware quality also have discretion, trigger different errors. So this paper also adopted various anti-disturbance measures to improve the reliability of system.
