Study On The Controller Of Solar Heating System

Solar heating technology is mature, but the effectiveness of solar heating system not only depends on the design of the pipeline, but also depends on the control system. Solar heating system includes three sectors: the collecting, the saving and the using of solar energy. If all these three sectors are done by the maintenance, then the work is large and the results may not be good. The microcomputer is very popular and now is widely used in industrial control and other fields. It is also feasible to control the solar heating system using microcomputer. So this article combines the microcomputer with solar heating system, and then designs a solar heating controller in order to make the heating system perform well.The main problem of solar heating system is the non-continuous supply of solar energy, freezing issues and the application of solar energy. According to this features, this article make a control strategy and then realize it by microcomputer. In the process of study, I choose the chip first and then draw circuit schematics, finally attain all function by programming. The controller has the following main modules: the clock module, display module, communication module, ADC module, key module. After finishing the controller, we use it in a project to test it. In the process of testing, we use a PC to collect the data for analysis.Through actual testing, the controller performs very safe and reliable. Through the analysis of data, the use of controller can save some energy. The controller is also designed with wireless communications, an innovative technology. This controller is easy to be produced serially and it will bring some social value.
