Research On The Anti-interference Techniques Of Control System For Intelligent Closestool Based On ATmega64

With the development of Chinese economy, people's quality of life is increasing. For the closestool, we have put forward higher requirements. The closestool has started from the traditional closestool to intelligent closestool. Thus, the domestic market on a lot of foreign intelligence closestool, but the high cost of these products, and some product design do not meet China's national conditions. This article is committed to design a low cost, fully functional, intelligent high reliability in line with China's national conditions intelligent closestool control system.The thesis uses ATMEL Company's AVR Series MCU ATmega64 as a host control chip and uses HT49R30 as a remote control chip. The following works have been presented in this project.1. First, according to the characteristic of embedded system and the requirement of the intelligent closestool, functional analysis and holistic design has been done. Then, According to the requirement the system, the thesis analyzes the characteristics of the relevant components, For better selection of chips and peripherals,we study the structure of Intelligent Closestool related components, characteristics, control theory. In order to improve intelligent closestool system stability, we research anti-jamming technology SCM.2. With the features of the control chip and control principle of various peripherals, hardware design and software design of the intelligent closestool embedded system have been done. In the part of hardware design, modularization design is introduce to enhance the maintainability of the hardware system. Hardware designs of the stepper motor drive module, transistor drive module, optocoupler isolation drive module have been emphasized. On the software part, we used the "from bosom to top " method. Above all, we designed the every single part of the function modules, and then assembled them together. We used the C language to write the program,and debugged them in the IDE ATMEL AVR Studio. Designs of stepper motor control program, IR receiver program and temperature control program have been emphasized. Focus on how to deal with modules and the advantages and disadvantages of modularization design are analysised. We introduce some anti-interference technologys and use them in intelligent closestool embedded system.3. Experiments of the both hardware and software system have been carried, field testing and the results are analyzed. The experiments show that the performance of the system is good.Based on the work in this thesis, the conclusion can be drawn that the intelligent closestool embedded system with functions of auto rush water, auto open and close, antifouling and deodorization, drying , cleaning, rubdown, energy-saving, infrared remote control, intelligent storage and memory is designed. It which is based on AVR MCU has high reliability,the virtues of high-performance and practicability. The Intelligent Closestool control system is through the production of the factory test. Results were very good and stable operation, meet their needs.
