Research On The Detection System For Early Tumour Based On ARM

The thesis has introduced design principle and method based on that tumour of ARM embedded system is detected in early days in detail. This system is considered from dependability, practicability, simple portable respect, adopt the hardware platform taking S3C44B0 processor as the core, and transplant uCLinux operating system on this hardware platformThe thesis has introduced the source of the subject briefly at first, and the basicprinciple of introducing hepatocarcinoma and diagnosing in early days briefly:Measure the tumour mark in the human blood - -Little content and change of TK1,offer the scientific basis for early discovery of the hepatocarcinoma patient. Thearticle enumerates the current situation of the development that domestic andinternational tumour diagnoses in early days, further explain the necessity of thissubject research and actual meaning.After had understood tumor early time detection basic principle, this article mainly carries on the system design from three aspects, first is the sensor design, because this topic is and several universities unit exploitation, the biosensor develops by the Jilin University and Hunan University, in order to could gather the data we to design to be able the quartz crystal sensor which used in the liquid phase. After has confirmed the sensor frequency measurement precision may answer the purpose, second step is carries on the hardware platform the design. According to the medicine clinical practice request, the article introduced inserts the type hardware platform based on Tristar ARM7 chip S3C44B0X the development, including connection electric circuit and so on system power source, CPLD, SDRAM and FLASH, USB, liquid crystal screen design. Transplanted the uCLinux operating system above this platform. Finally is carries on each connection electric circuit the software design.This article elaborated inserts the type system development the general process, it inserted the type tumor early time diagnosis system the development to provide one effective method, also has provided one kind of beneficial senate for other tumor examinationsThe main works as follows:1. Hardware components: the design of the plug-in S3C44B0 processors at the core hardware system, with a focus on USB interface and LCD.2. Software components: an embedded operating system uCLinux transplant on the hardware system, including uCLinux presentations and the focus transplant. And in an embedded operating system for software design.
