【摘要】 在太阳能的热利用中,用于产生热水的太阳能热水器应用广泛,它充分利用了环保型能源—太阳能,这对于当今资源紧张的时代,具有重要的意义。太阳能热水器己成为中国可再生能源市场上需求量最大、发展最为迅速的产品之一。然而,目前我国市场上的太阳能热水器控制系统大多采用微控器芯片,这种系统功能单一,操作复杂,控制不方便,抗干扰能力差,而且不能够对水温进行良好的控制。基于上述原因,本文依据模糊控制算法,以FPGA芯片为主体,设计了一套具有太阳能加热与电加热结合的调温模糊控制系统。这套系统具有以下优点:可以自定制指令、可在线修改硬件电路、外部扩展能力强、使用方便、开发周期短、开发费用低。本系统利用集成开发工具MAX+PLUSⅡ进行综合、仿真,采用自顶向下的设计方法,对系统进行设计。首先,设计了外围硬件电路模块,主要包括:温度检测模块、按键输入模块、显示模块、FPGA模块、水位检测模块、上水电路控制模块、加热控制模块;其次,采用自顶向下的设计方法,在FPGA内部设计了硬件电路模块,主要包括:定时模块,时序控制模块;然后,对各个子模块进行功能与时序的仿真;最后,在顶层进行硬件系统整体设计。本文将智能化控制技术应用在太阳能热水器的辅助加热温度控制电路中,为建立精确数学模型的被控对象提供了一种有效方法,力求在满足经济性、实用性、科学性的条件下设计一套稳定、可靠的系统。更多还原

【Abstract】 Among the applications of the solar energy, heat collector of solar energy for heating water is being extensively applied. Through exploring the energy from the nature, this technology is particularly important for today’s society to relieve the stress from lack of sources. The solar heater product has become the one of the products which have rapidest development and biggest demand in our renewable energy source market. However, the current market, the control system of the Solar Water Heater constitute of the MCU chip in the large number. This system has some bad effects. Such as less function, complicated operation, inconvenient control, poor anti-jamming. Besides this system has bad the effect of control to water temperature.Based on the above reason, the paper rested on the fuzzy control algorithm, taking the FPGA chip as the main body, designing a set to have the solar heating and the electric heating union constant temperature fuzzy control system. This set of systems have the following merits: may had custom-made the instruction, the online revision hardware circuit to be possible, the exterior expansion ability to be strong, the easy to operate, the development cycle is short, the development cost is low.This system used integration development kit MAX+PLUSⅡ, using the design method up - bottom. Firstly, it designed outer hardware circuit module, including temperatrue test module, Keyboard circuit module, Display module, FPGA, water test module, water control and temperature control module. Secondly, it adopted a way from top to bottom and design each small module, involve: time module, processor. it have made function and time debugging. Finally, in the top, it give the graphic editor file.This paper study the aiding heat system of solar energy heat collector by adopting intellectual technology, the main task is that designing a system of reliable and steady thermostatic control on condition that economical efficiency, practicability, scientific.更多还原
