Under this requirement, designed a water temperature based on singlechip microputer control system with SCM as the core pleted reality heating water temperature, temperature measurement, temperature and the alarm lamp function. System uses a DS18B20 collected temperature, set the desired temperature with the keyboard, the set temperature and actual temperature through the digital display, automatic alarm when temperature has reached the set temperature. Through the design of temperature control system based on singlechip microputer experiment showed that SCM as the core can realize temperature control, can also be set according to user39。s needs. The system is widely used in that system improvements can be achieved on the basis of a better use of. In industrial production of temperature, pressure, flow, and level are four monly used physical quantities, where the temperature is a very important process because it directly affects the bustion, chemical reaction, baking, roasting, calcination, distillation, concentration, extrusion, crystallization, and air movement, and other physical and chemical processes. Temperature control is widely used in industry, because of their number, parameter, variable, influencing factors operating control of large inertia, hysteresis characteristics, so the control regulator to demand higher. Poor temperature control can cause the production safety, product quality and productivity and other problems. In the parameters of the water temperature is often used in everyday life, such as water coolers, water heater, hot tub, pool, needed to control the water temperature, so as to make people39。s lives easier. For this system,Is 89C51 SCM as the core, with the temperature sensors, signal processing circuit, display circuits, output control circuits and other ponents, software using c language programming. Monolithic temperature sensors to monitor water temperature, displayed on the LED digital tube display, to heat the water temperature can be set according to the user, and when the set temperature is above or below the limit temperature alarm. System flexibility, ease of operation, high reliability, and will have broader prospects for development in the future.KEY WORDS:SCM,temperatre control,DS18B20第一章 引言 隨著科學(xué)技術(shù)的進(jìn)步，水溫控制在生活中的地位越來(lái)與重要，水溫控制系統(tǒng)在溫度控制區(qū)域受到廣泛的應(yīng)用。 系統(tǒng)設(shè)計(jì)的背景 在能源日益緊張的今天，電熱水器，飲水機(jī)，電飯煲之類的家用電器在保溫時(shí)，由于其簡(jiǎn)單的溫控系統(tǒng)，利用溫敏電阻來(lái)實(shí)現(xiàn)溫控，因而會(huì)造成很大的能源浪費(fèi)。本系統(tǒng)是以AT89C51單片機(jī)為核心，配合溫度傳感器，信號(hào)處理器，顯示電
