Study On Embeded Remote ECG/BP Recorder Base On UClinux

Embeded system industry is continuously developing swiftly and violently in these years,which has been widely applied to many fields,such as mobile computing device,network device,industrial device,information appliances,automobile electronic,amusement establishment,apparatus and instruments,etc.In this background,this paper integrated the source-opened Linux and embedded graphic user interface and modern microprocessor technology together and developed the remote ECG/BP recorder.The recorder based on the S3C44B0X processor of Samsung, source-opened embedded uClinux operation system,and transplantable graphic user interface—Micro Windows and some other components to meet the request of portable usage.This paper introduced and resolved following question,such as designed the hardware system,introduced the basic concept of the bootloader and port the source-opened bootloader—U-Boot to the recorder;modified some source file of uClinux to meet the request of the recorder and port to it;designed the button module and the data sampling module drive and the application user interface for those two device drive;introduced the structure of Framebuffer,which widely used in linux system,and how to modified to meet the resquest of the lcd controller of S3C44B0X processor and the 16-level gray scale LCD;introduced the MicroWindows's structure and port to the recorder,and last designed some application of the ECG/BP recorder,for example the BP measure module.system information manage module, the ECG data analyse module ,data remote transmit moudule and so on.
