摘 要
近些年來，隨著汽車行業的飛速發展，汽車消費成為現代社會的一個巨熱狂潮，所引發的又一輪絕好商機是被稱為汽車后市場的汽車用品業。車載飲水機也就在這個時候應運而生。
車載飲水機的出現解決了有車族在自己的“愛車”上或是公安干警、部隊，還有長途客貨車司機在野外時能隨時隨地喝上熱水的難題。車載飲水機上的熱水可用于沏茶、沖咖啡、泡方便面等，為駕車外出提供了極大方便。
本課題就是進行車載飲水機的設計，硬件部分主要采用AT89C51型單片機進行主控制，再加溫度和水位測量等輔助電路，用Protel繪制硬件原理圖，軟件部分用C語言進行編程，通過軟硬件結合和實現各功能模塊間的連接通信，完成系統設計要求。最終實現水的加熱，余水回抽，無水自動報警，語音提示等功能。設計出一臺功能較全，經濟實惠的車載飲水機，讓您在需要時輕輕松松就能喝到一杯熱水。

關鍵詞 :  飲水機；車載用品；單片機

Automatic Vehicle drinking fountains

Abstract
In recent years, as the rapid development of the automobile industry, automobile consumption of modern society has became a hot giant waves, triggered by another round of excellent business opportunities is known as the car market after the vehicle equipment industry. The car drinking fountains at this time came into being.
The car appeared to solve the problems : “car owners” in his car or public security police, the armed forces, there are long-distance passenger and goods vehicle drivers in the field at any time when they want to drinking waters. The hot water supplies by car drinking fountains can be used for tea, salt coffee, instant noodles and other foam, to provide motorists on a great convenience.
This issue is the drinking fountains for automotive design, some of the major hardware used AT89C51-SCM control, coupled with the water level and temperature measurements, and then Protel schematic rendering hardware, software some with C programming language, through the hardware and software Integration and achievement of functional connections between the communications module to complete the design requirements. The ultimate realization of water heating, Pumping the remaining water ,anhydrous automatic alarm, voice prompts, and other functions To design a more full-function, design reasonable, affordable car drinking fountains, so you can easily enjoy a cup of hot water while need .
