Development And Optimization Research Of Graphic User Interface For Embedded Electrocardiogram Monitor System

Cardiopathy is the great threat to human's life. The existing hospital monitor can't be satisfactory to the need used at home at any moment because of the characteristic of cardiopathy, such as transient and abruptness. Now the new type of portable electrocardiogram monitor need be created for detecting and playback on occasion. So the graphics user interface (GUI) is playing an important role in it. It must be used for real-time playback besides the general demands for menu and windows. But it's hard that EMS memory and rate of travel of CPU can be satisfactory to the above-mentioned restrict at the same time. So the main tasks are to search for the optimization between the EMS memory and efficiency of GUI system premise of the limit of size and power consumption and the requirement of operational speed and then to create the high operational efficiency GUI for portable electrocardiogram monitor while occupying the least EMS memory.The main tasks and results of this dissertation are summarized as following. (1)Composing theμC/OS-II embedded operating system bases on the microprocessor ARM7 LPC2292 under the hardware platform. (2)Transplanting ofμC/GUI based onμC/OS-II. (3)Analyzing the situation of optimization between the occupying of EMS memory and efficiency ofμC/GUI and bringing out the method separated loading. (4) Designing and compiling the program for GUI of portable electrocardiogram monitor.The method put forward in this dissertation to design the GUI of portable electrocardiogram monitor based on the optimization between the occupying of EMS memory and efficiency can reduce the CPU running frequency while spending less EMS memory. So the power consumption and cost of portable electrocardiogram monitor can be reduced and it will be used extensively.
