 本次設(shè)計(jì)選擇數(shù)字電子式電機(jī)保護(hù)方式（單片機(jī)控制保護(hù)方式），該保護(hù)裝置選擇利用單片機(jī)這一廉價(jià)的智能塊去換取PLC的昂貴部件，且其在軟硬件方面比繼電器控制保護(hù)式的、模擬電子保護(hù)式的都具有顯著的優(yōu)勢(shì)。該設(shè)計(jì)由主從機(jī)兩大部分組成，結(jié)合集成電路的應(yīng)用及單片機(jī)控制的多種知識(shí)，利用功能強(qiáng)大的單片機(jī)技術(shù)，完成智能保護(hù)器的硬件電路設(shè)計(jì)，并編制完整的電動(dòng)機(jī)保護(hù)程序，最終實(shí)現(xiàn)過壓、欠壓、過載等多種保護(hù)功能。本文的著重點(diǎn)在于介紹主從機(jī)間的通信方式、主機(jī)部分各模塊的軟件設(shè)計(jì)、單片機(jī)的抗干擾性能等。

Title    Motor Intellectual Protection System                  

                  —The Mainframe Software Design                                   

Abstract
This design adopts the digital electronic protected mode for electric machines (i.e. protected mode based on single chip control), which uses the low-cost single chip to replace expensive parts of PLC. Moreover, this mode has obvious advantages on software and hardware as compared to both relay-control protected mode and analog electron-control protected mode.
The design content includes design for both host frame and slave frame. In this design, on the ground of the application of integrated circuit and relative knowledge on single chip control, the powerful single chip is used to fulfill the circuit design for hardware of intelligent protector and the program for motor protection needs to be compiled to achieve the protect function under various conditions such as over-pressure, under-pressure and overload. The key point of this thesis is to introduce the communication mode between host computer and slave computer, the software design for each modules of host computer as well as the anti-interference capability of the single chip.
