畢業(yè)設(shè)計 基于單片機的供暖鍋爐控制系統(tǒng)設(shè)計，正文共22頁，7554字，附任務(wù)書、開題報告、中期檢查表。
摘要
本設(shè)計是基于單片機的水暖鍋爐控制，在設(shè)計中主要有水位檢測、溫度檢測、壓力檢測、按鍵控制、水溫控制、水位控制、循環(huán)控制、壓力控制、顯示部分、故障報警等幾部分組成來實現(xiàn)供暖控制。它主要用水位傳感器檢測水位，用數(shù)字溫度傳感器DS18B20來檢測水溫，用五個控制按鍵來實現(xiàn)按健控制，用三位LED顯示器來完成顯示部分，用變頻器來控制循環(huán)泵的轉(zhuǎn)速，用壓力傳感器檢測鍋爐內(nèi)部壓力。并且通過模數(shù)轉(zhuǎn)換把這些信號送入單片機中。把這些信號與單片機中內(nèi)部設(shè)定的值相比，以判斷單片機是否需要進行相應(yīng)的操作，即是否需要打開鼓風(fēng)機，是否需要開啟補水泵，是否需要加快循環(huán)泵的轉(zhuǎn)速等操作，從而實現(xiàn)單片機自動控制的目的。本文用單片機控制易于實現(xiàn)鍋爐供暖、而且有造價低、程序易于調(diào)試、一部分出現(xiàn)故障不會影響其他部分的工作、維修方便等優(yōu)點。

BASED SCM DESIGN OF HEATING BOILER CONTROLLED SYETEM
Abstract: The systemic design bases controller of SCM water heating of a boiler, it mostly makes up of measuring water level, measuring a water temperature, controllin- g a keys-press, controlling a water temperature, controlling water level, controlling ci- rculate, controlling pressure, showing a part, giving an alarm order to realize heating controller, the design adopts Single-Chip Microcomputer to control boiler heating .It mostly uses a temperature sensor DS18B20 to measure water temperature, uses water level sensor to measure water level , uses a transducer to control cycle pump’s rotate speed ,uses five keys-press to control key-press, uses three light-emitting diodes diap- lay to finish a display parts ,uses a transducer to control rotate speed of cycle pump , uses a press transducer to measure press in the boiler .It sends those signals to SCM through modulus ,and hold those signals to compare with enactment in the SCM to j- udge whether SCM need to carry through relevant operation namely ,whether it needs to open a fan ,whether it needs to turn on a water pump ,whether it needs to quicken rotate speed of a cycle pump and so on . Consequently, it finishes an aim of SCM au- to-controller. The design makes use of the SCM to control a boiler that is easy to rea- lize boiler heating, it is cheap to manufacture, it is easy to debug its procedure. When a part is in trouble, it does not infect others and it is convenience to mend, it is widely to use many of areas.
Keywords: Single-Chip Microcomputer, transducer, water level, water temperature, Auto-control
