Research And Achievement Of The Data Collection System Based On ADμ C812

In recent years, with the rapid development in embedded microprocessor, the SCM(Single Chip Micyoco) has been widely applied in many fields such as the medical treatment,the aviation, the transportation, the military technique, the industry, the science research, andso on. In this fields, SCM is usually to be used as a core parts, but the knowledge of SCM isn'tenough. We should combine with the structure of concrete hardware and characteristics ofrelevant software to design the system. The purpose of this thesis is to design a practicalreal-time data collection system.This thesis mainly discuss the design and realization of the data collection system whichrefers to the temperature,humidity,pressure inside the soil. The system is mainly used tofinish the data collection,processing,display and the correlative control and communicationwith the PC. On the analysis of the system structure and function requirement, the system inthis thesis adopts the ADuc812 core, expands the power,reset,LCD interface circuit withstandard RS-232 series communicate interface. For the entironment the system in use iscomplex with serious disturb. We should ensure the reliability and security besides the basicfunction in the design of the system.In this thesis we discuss the anti-jamming measuresthrough hardware and software. We talk about the realization of communication with thePC .The software design with assemble language, and adopts modularize framework design .Firstly, the thesis introduces the design structure of the system and the correlativedevelopment entironment. In the deep discuss of the system, it describes the key techniqueand design concretely. We talk about the hardware design,circuit board analysis and the otherissue worth thinking about in the design. We attempt study the design process of the softwaretoo.
