ABSTRACT
With the development of society and the progress of science and technology, people's living standards are gradually improving. However, problems come with it, such as the energy crisis and environmental pollution, thus green development ideas gained ground. Solar energy as a new clean energy has been widely recognized, due to that it’s inexhaustible and clean, and followed by a major feature. So, promoting the use of solar energy actively is of great significance. This article will set out to design an intelligent, high-performance solar water heater control system which was designed with intelligent automation features. This design can be used as a separate control system sales also it can be installed on ordinary solar water heater to make it as a smart water heater to sell. The design will be more beneficial to promote the use of solar energy. Combined with the internet of things will attract the attention of consumers in the future and be in line with the country's current development concept.
This paper describes the basic features of the microcontroller, sensors, real-time clock, and a detailed illustration of the working principle and design of solar water heater control system. According to the design requirements, STC89C52 used here as a master chip. Other hardware includes: temperature acquisition module, water level monitoring module, key input section, LCD display window and relay control module, relay control module has automatic pumping water part and programming heating part. On the software side, using modular design makes the works steady progress. After simulation, each module of the system is working properly, which meeting to the design requirements.
