Abstract

This design AT89C51 microcontroller as the core of the temperature control system working principle and design method. The temperature signal is collected by the temperature chip DS18B20 and transmitted to the MCU in the form of digital signal. This paper introduces the hardware of the control system, including MCU circuit, temperature detection circuit, temperature control circuit and so on. Single chip microcomputer through the corresponding signal processing, so as to achieve the purpose of temperature control. The paper also focuses on the software design, here using modular structure, the main modules are: digital tube display program, keyboard scanning and key processing program, temperature signal processing program, relay control program, overtemperature alarm program.

Air conditioning temperature control for industrial and daily life and other projects have broad application prospects. With the development of micro electronic technology and embedded system in China, the current relatively traditional canteen air conditioning system can not meet the needs of customers. In order to improve the traditional canteen air conditioning system in the control of the short board problem, in this graduation project, will use relatively advanced, fast, intelligent control mechanism. The control brain of the system is the core controller of the 51 series embedded development system, which mainly uses digital control technology to convert the input continuous analog voltage signal into discrete digital signal and transmit it to the LCD. The canteen air conditioning system design has intelligent control, digital display and other functions, and cost-effective, accurate, low energy consumption, simple production, fast control and other characteristics, has brought a great impact on people's lives, is very popular in the market.

Air conditioning temperature control for industrial and daily life and other projects have broad application prospects. In this paper, the traditional control theory and intelligent control theory combined with the application of thousands of temperature control in the actual project. First, design the hardware structure of the system. On this basis, this paper analyzes the advantages and disadvantages of the existing air conditioner control methods, and their respective advantages and disadvantages. The intelligent control system design mainly from the domestic and foreign development, the choice of hardware control components, according to the control principle to draw the hardware circuit, control system software program design and development, software and hardware joint adjustment simulation four aspects in detail. The control system uses AT89C51 embedded development system, sensor signal acquisition circuit, circuit display part, data conversion circuit, reset circuit and clock circuit to form the canteen air conditioning system. C language was used for code development, Keil software was used for code design and writing, Proteus was used for simulation, and finally the system performance requirements were met.
