The Research And Design On Wireless Endoscope Location System

From 19 century when the direct endoscope studied to 21 century when the wirelesselectronic endoscopes studied, About 150 years of studies and developments,the endoscope had takenan important role in the modernistic diagnosing medical instrument. Especially In recent years, wirelesselectronic endoscopes with characteristics such as base on computer systenu high-resolution,electronic formation of image,indolence have appeared, and have been taken into practice. wireless endoscope image on the basis of the computer system has not only making it be convenient for doctors to observe and diagnose,but also improving the clinical efficiency and veracity greatly, reducing the doctors' error diagnose, alleviating patients' pain. Achieved slim hurt and indolence. The location system is the part of the wireless endoscope system indispensability. This paper's study bases on the former background. Developing the wireless endoscope Location system and display equipment.From both theory and practice, the paper discusses deeply with the location theory.Analyzing and designing the software hardware and display of the wireless endoscope location system. In the article in detail introduced the permanent magnet model three dimensional finite element model establishment, the analysis process and the analysis result.we analyse the result which based on the locating method based on the principle of three points location theory,then predigesting the permanent magnet model. In the article,we study the wireless endoscope location arithmetic based on the locating method based on the principle of three points location theory. Advanced location system equipment which based on DSP. Developed a series of stady based on the design and application of the location system.which include the application system design of TMS320LF2407, analysed and predigested the principle of three points location theory, permanent magnet magnetic field finite element analyse, syudied columnar permanent magnet magnetic field model based on the equivalent magnetic charge method, differentiation sensor detect area and switch when sensor set the other senser detect area.
