Research On Intelligent Heating System In Rural Areas

In the construction of new rural, to improve the the environment of their life and production, heating problem becomes one of the key issues. So far, the main heating means is the burning of coal in rural areas. However, due to backward heating equipment, the efficiency of heat source is low in most heating process, and environment is seriously polluted. In addition, the rural buildings disperse relatively, and it can receive adequate sun light. So the solar heating has a good prospect, which can improve the living environment and save energy source. Also in the process of temperature control, it’s always necessary for people to operate heating equipment, and the control precision can not meet the requirement, which brings inconvenience to their life. Intelligent control system can adjust the temperature automatically, and then the speed and accuracy of control are improved.In cold areas, available solar energy is often less than heat required for heating system, therefore, electric heating equipment is used to supplement heat source. This paper researches embedded intelligent heating system. According to the supplied case of solar, electric heating equipment is controlled to provide sufficient heat radiator heating. The system uses the temperature sensor DS18B20to collect temperature, and control algorithm processes the deviation of collected temperature and set temperature. Finally, the system gets the control volume to control implementing agency of the system that electric control valve. So through the control of heating water flow, we can reach the purpose of temperature control.This intelligent heating system uses the ARM processor S3C2440, and designs the peripheral circuit, including temperature control circuit, temperature acquisition circuit and LCD display circuit and so on. This paper also studies the algorithm of the system, and uses complex control algorithm based on fuzzy PID and NN PID. Then this paper uses MATLAB to simulate algorithm.This paper using the Linux as the operating system, and builds the development environment of the embedded system. The system establishes a cross-compiler environment, at the same time, transplant Bootloader and kernel, and establish a root file system. Finally, the paper develops drivers and applications...
