摘 要
隨著供暖方式向個性化、舒適化、環(huán)保和節(jié)能化方向發(fā)展，對供暖系統(tǒng)的性能提出了越來越多的要求。本系統(tǒng)是為電采暖散熱器控制而設(shè)計的。散熱器控制器以PIC16F877作為主控制器，采用模糊控制原理實現(xiàn)了散熱器能量供給的自動調(diào)節(jié)和節(jié)能控制。本系統(tǒng)所設(shè)計的智能溫度控制器是以集成溫度傳感器LM35D為檢測元件，對室內(nèi)溫度進(jìn)行實時數(shù)據(jù)采集、轉(zhuǎn)換與處理，并與給定溫度進(jìn)行比較，運用模糊控制算法對溫度偏差和偏差變化率進(jìn)行模糊調(diào)節(jié)，得到輸出量對散熱器交流電路一個周期內(nèi)通電與斷電次數(shù)的固態(tài)繼電器進(jìn)行PWM控制，加熱散熱器，實現(xiàn)對室內(nèi)溫度的自動調(diào)節(jié)。由于在自動調(diào)節(jié)的作用下，控制了散熱器的實際加熱功率，實現(xiàn)了節(jié)能高效控制，同時此溫度控制器還可以實時顯示溫度值，手動設(shè)定溫度值，給用戶帶來了方便。

Abstract
With heating system development in the direction of personality, comfortable, environmentally and energy-saving, there is an increasing number of requests to the heating system’s performance. This system is designed to control the electric heating. The controller is selected PIC16F877 as the main controller and used the fuzzy control principle, realized the heating energy supply’s automatic control and energy-saving control. The intelligent temperature controller which designed for this system selects the integrated temperature sensor LM35D as the testing components, realizes the indoor temperature acquisition, conversion and processing, and then compares it with the given temperature. Control algorithms used fuzzy logic control algorithms which conduct fuzzying and fuzzy-back to the temperature deviation and its variety rate for the output, then this output will use the PWM to control the number of solid-state relay on-off in one period of the radiator’s AC circuit, then heat radiator, and realize the feedback and regulation to the indoor temperature. As the role of the automatic feedback adjustment, the system have controlled the actual heating power of the radiator, and have also achieved a highly efficient energy-saving control, while the temperature controller can also display the real-time temperature, set the temperature manually. So it brings much convenience to user. Key words: radiator; temperature; SIM PIC; fuzzy control; automatic control;
