文檔簡介

1、此文檔是畢業(yè)設(shè)計(jì)外文翻譯成品( 含英文原文+中文翻譯) ,無需調(diào)整復(fù)雜的格式!下載之后直接可用,方便快捷!本文價(jià)格不貴,也就幾十塊錢!一輩子也就一次的事!外文標(biāo)題:Based On Single Chip Microcomputer Heating Temperature Automatic Control System外文作者:De Yong Liu, Hong Song, Zhi Qiang Kong 文獻(xiàn)出處: Advanced

2、Materials Research Vols. 591-593 (2019) pp 1664-1668 (如覺得年份太老,可改為近 2 年,畢竟很多畢業(yè)生都這樣做)英文 2423 單詞,15149 字符,中文 3704 漢字。Based On Single Chip Microcomputer Heating Temperature Automatic Control SystemKeywords: AD590, ADC0809, A

3、T89C51, CD4511.Abstract. The temperature control is one of the most common control system,with the development of the sensing technology, new single-bus digital temperature sensor to achieve faster development of the tes

4、t and control of the temperature. The system is a temperature sensor AD590 to acquisition analog signals, after ADC0809 converted into digital signals to 89C51 single chip processing, so as to achieve the collection of t

5、emperature, and then through the CD4511 drive seven sections LED display. The system can control of temperature, through the keyboard for temperature of add or subtract Settings, if detection temperature is more than set

6、 temperature, stop heating, if detection temperature is below the set temperature, start heating. The system of design and wiring are simple,easy extension, cost-effective, volume is small, compact structure,strong anti-

7、interference ability.Fig. 1 System structurethe System Hardware Circuit Diagramthe Main Control Circuit. MCS-51 is an 8-bits CPU, 128B data storage, 4KB program memory, five interrupt source, and two 16-bit timers/counte

8、r, one serial port, four parallel 8-bit I/O and twenty-one special function of registers. The most basic circuit of the single chip microcomputer is able to make SCM normal start and work of the circuits, including power

9、 VCC termination +5V voltage, VSS grounded. Due to the low electric pins EA at ordinary times is to visit piece of external storage, the system does not need to expand outside of memory, so it need to maintain a high lev

10、el, connect the power supply voltage +5 V.the Clock Circuit. MCS-51 internal have one for a reverse phase of high power gain oscillator amplifier, the high power gain reverse phase of the amplifier input for chip XTAL1 p

11、in, the output for chip XTAL2 pin. The two pins jumper quartz oscillator and fine-tune capacitance transistor, they form a stable of self-excited oscillator circuit of capacitance C1 and C2 typical usually choose to abou

12、t 30PF, the oscillation of the crystals usually between 1.2MHz frequency and 12MHz. The higher the crystal frequency, the system clock frequency is higher , the running speed of single chip microcomputer also more quickl

13、y. MCS-51 often choose concussion 6MHz or 12MHz frequency of quartz crystal, the control system choice 12MHz.Reset Circuit. MCS-51 reset by external reset circuit to realize, reset circuit of single-chip processor is ini

14、tialized operation, make SCM in its initial state. One level reset through the resistance and power supply the RST +5V connected to fulfill. When quartz crystal frequency for 12MHz, reset circuit parameters for 1uF elect
