20、動(dòng)化，既安全可靠又快捷方便。本文主要是設(shè)計(jì)一種全自動(dòng)咖啡機(jī)的整體工作方式，包括磨豆裝置，加水燒水系統(tǒng)，釀造裝置。它的控制系統(tǒng)以89C51單片機(jī)為核心，附有溫度傳感器，流量計(jì)，按鍵系統(tǒng)，加熱電路，各種開(kāi)關(guān)以及液壓裝置來(lái)完成整個(gè)系統(tǒng)的控制。對(duì)于機(jī)器里的核心部件，本設(shè)計(jì)給出機(jī)械CAD圖，如研磨機(jī)構(gòu)，釀造室，以及液壓原理圖。對(duì)于整個(gè)機(jī)器的控制部分，本設(shè)計(jì)從硬件軟件兩方面利用protel給出了電路接線圖以及C語(yǔ)言程序。關(guān)鍵詞：研磨機(jī)構(gòu)、液壓系統(tǒng)、
