Abstract
Today, the temperature control has become a key technology in various areas. In some areas such as in aviation, chemical, metallurgy, medicine, and other areas, temperature control results directly affect the quality and life of many products, therefore, the temperature control of high-performance’s device has a very important significance. Both temperature and temperature control is the key to temperature control; temperature measurement is the basis for temperature control, temperature control room temperature measurement of the extension. Compared to more mature in terms of temperature measurement, temperature control, there are still many problems, as more complex control object appears, the people have to constantly look for better control methods to improve the control technology to meet the ever-changing control requirements. Temperature control system turned around temperature sensor and microcontroller core. Therefore, in order to improve awareness and understanding the sensor and the microcontroller this graduation design combined with the microcontroller and sensor technology to design of the system. The main task is to complete the design temperature detection, temperature monitoring at the same time and use computer-implemented single chip temperature controller. The design of the main tank as the application of temperature control, make some modifications, it can be applied to other temperature monitoring system. In this paper, the design system includes a temperature sensor, microcontroller, heating and cooling control, data transmission, computer and relay drive circuit of six parts. Implementation process and capabilities are described in detail. Main function is to achieve temperature control, so it can complete the graduation requirements.
