The Family Of Portable Medical Monitoring Device And Design

With the development of society and technology, there comes the aging time and the improvement of the quality of people's lives, which brings the great charge of people's health attitude. Furthermore, medical care is stepping into illness preventing and nursing care, form traditional cure of illness, then comes out HHCE, which advocates that medical care is shared at home. With advanced and appropriate medical equipment being equipped, custody, diagnosis, health recovery and health care can all be offered to the patient at home. On the other hand, the telemedicine has become an indispensable part of human life as the developing of internet technology. It can transmit medical information (biological parameter) to a distant doctor and gains care guidance or even rescue which staying at home. The telemedicine is not region limit, and share the medical resource and improve the level of medical treatment on jumping-off, at the same time it also reduces medical service cost and time.Now, with the development of HHCE and telemedicine, the HHCE devices for end-user are springing up constantly. According to the study of market and the development trend of medical monitoring equipment, we mainly research the solution of telemedicine monitoring equipment with multifunction and convenience. It can be applied for person,family,community and doctor, and can provide with data acquisition, parameter analysis ,display, storage , transmission and long-distance control, so it combines health care and telemedicine. At the same time, the design adopts SOPC Technology to integrate the system on FPGA, and make the monitoring equipment enjoy small size, low power loss, convenience.This paper mainly introduces the hardware and software design and how to realize teamwork between hardware and software. Through the demand analysis and project approachment, our design adopts Altera SOPC Technology to develop the hardware platform. The system selects DE2 FPGA development Kit, which is produced by terasic, as development platform. This board has plenty of resources to make our design more convenient, simultaneously, the Nios II soft-core processor and lots of IP cores, which is produced by Altera, also improve the design efficiency and quality.First, this paper mainly presents how to structure the hardware platform, including the circuit design of data acquisition module based on the biomedical signals, the design and test of important IP core and how to build the SOPC system. And the followed the design of software programs. To achieve the system multifunction,multitask and multithreading, the software development is in process after uC/OS II operating system is transplanted. In this part, it mainly introduces how to develop device driver based on HAL, how to transplant and apply uC/FS,uC/GUI and TCP/IP, and the study of DSP algorithmic. Finally, the paper shows the system test performance,parameter and function. The results shows that our telemedicine monitoring system can reach the design requirements on functions,performance and stability.
