Based On STC12 Series Mcu Design And Implementation Of Intelligent Temperature And Humidity Control System

Temperature is an important physical quantity. It is one of seven basic physical quantities International System of Units(si), and is also a major industrial production processes, but to accurately measure the temperature is very difficult, no matter how high accuracy thermometer, if the thermometer improper selection or test methods unsuitable, it can not get satisfactory results. We can see the importance of temperature measurement technology and complexity. With the advent of the knowledge economy is characterized by the information age, the level of industrial automation, manufacturing increasingly high degree of fine control of the production process is gradually deepened, and the temperature and humidity as an industrial manufacturing process of the most important parameters First, their detection and control requirements are also increasing.Due to the high reliability of the application system consisting of microcontroller, system configuration specifications, the control function with expected resistance, easy change of control scheme, has a high cost-effective features, be utilized in industrial production more widely. Select this article STC12C5A60S2 series microcontroller as temperature and humidity control system processor, 12864 LCD display as the system output, with four physical buttons through the completion of the system time, temperature and humidity values, such as the default parameter settings, in addition to be able to show detecting an ambient temperature and humidity outside the temperature and humidity of the system can also be controlled in response to the set value. The first chapter is mainly an overview of methods and means of temperature and humidity measurement and control technology, the second chapter analyzes the system design, and then need to use the devices, communication protocols, platform development environment were fundamental groundwork; first chapters are mainly hardware circuit design system of each module; fourth chapter noted that the system software design; Finally, the performance test of the entire system.
