摘    要

 在啤酒發(fā)酵過(guò)程中，溫度是主要參數(shù)，以往采用人工定時(shí)觀察溫度計(jì)的方法來(lái)控制發(fā)酵溫度。這樣，不僅勞動(dòng)強(qiáng)度大，而且容易造成數(shù)據(jù)不完整或不準(zhǔn)確。隨著微型計(jì)算機(jī)在工業(yè)過(guò)程中的應(yīng)用，解決了以往的問(wèn)題，所以，本設(shè)計(jì)采用微型計(jì)算機(jī)對(duì)啤酒發(fā)酵過(guò)程進(jìn)行實(shí)時(shí)控制，以便達(dá)到優(yōu)質(zhì)、高產(chǎn)、低消耗和提高企業(yè)的經(jīng)濟(jì)效益的目的。
 針對(duì)系統(tǒng)大慣性、大遲延的特點(diǎn)，我們采用PID控制算法。
 我們采用8031微處理器及外部存儲(chǔ)器組成最小系統(tǒng)，加上前向通道和后向通道配置，最后配備鍵盤(pán)、鼠標(biāo)、顯示等人機(jī)通道配置，來(lái)完成對(duì)控制系統(tǒng)的溫度進(jìn)行實(shí)時(shí)檢測(cè)、轉(zhuǎn)換、處理、等控制。使啤酒的質(zhì)量和產(chǎn)量有了進(jìn)一步提高。

The system that control beer ferment by microcomputer

abstract
 During the process of beer ferment ,temperature is the main parameter, people generally by the way that artificial observe thermometer to control the ferment temperature in the former. Like this, not only the strength of labor very large but also it is very easily to make for data not complete or not accurate. Along with the application of microcomputer in the process of industry , the former problem are resolved, so, this design controls the process of the beer ferments in the real time by the microcomputer , in order to attain superior quality, high produce low depletion and reach to the purpose that increases economic benifit of the enterprise 
 aiming at the Characteristics of the big inertia and big delay in the system, we adopts the control calculate of PID.
 We adopt 8031 microprocessors and exterior storage constitutes the minimum system, plusing front face passage and behind passage, finally provide with the passage installs of someone the machine including keyboard, rat, vision to  the temperature proceed real time examination, convert, handles, etc. .Make beery quantity and output have a big improve in the yield.

Keywords :8031  control  ferment  temperature
