In the era of "post-PC", embedded system is regarded as a new representation .With its qualities of strong functions, strong real time, compact structure, high reliability and low power consumption , nowadays embedded system has been wide applied to many fields of our lives.Induced Polarization method (IPM) is one of the most effective methods in effective prospecting methods and is developed till now. The development is specially focused on the design of observation system and theory and application of IPM. The Tri_frequency Induced Polarization Observation System(TFIPOS) , developed from DoubleFrequency Induced Polarization Observation System, is a new induced polarization observation system. It characterizes with strong anti interference power, strong resolution power, higher prospect depth, anti complex coupling and ability of distinguishing abnormity. We design embedded system on the basis of TFIPOS for further development.This paper is developed around the designing of the embedded system of frequency domain induced polarization coherence detection. At the first, it discusses the theory and application of embedded system, then the basic knowledge of embedded operation system is discussed. The paper emphasis on how to complete designing the precision coherence detection instrument embedded system(PCDIES) with the embedded computer. It is discussed in detail in this paper on two sides: one is the designing of hardware system, the other is the programming of software. After finishing designing, the PCDIES has many feathers: low power consumption, less size, higher observation precision, strong ability of function extended and enable to used for developing platform.This paper successfully designs the precision coherence detection embedded system, its quest for development model has the meaning of being used for reference in the development of other induced polarization instruments as well. |
