| Since the last century of 90s, embedded systems have involved all areas of information technology with the development of computer technology, Internet technology, information technology,it aroused a lot of integration and integration into the rapid stage of development. In this paper, remote physiological data acquisition system is based on embedded Web server, an advanced Web technologies, multi-processor embedded system is used in telemedicine digital instrument design, which achieves Telemedicine, and promote the "National Medical Insurance ".The most important terminal equipment of the entire system is Physiological Parameter Acquisition Instrument,it can collect ECG, heart sounds, carotid wave blood pressure and some physiological signals on time, with real-time transmission, Telemedicine system supplement the diagnosis a doctor or expert, reducing the diagnosis time delay, increasing diagnostic efficiency, the timely provision of medical services in a certain extent.This paper describes the Realization process for Physiological Parameter Acquisition Instrument. The whole system uses browser/server model. It consists of sensors, signal pre-processing circuit, A/D converter, digital signal processing module,32-bit host module and the network interface and some other components. Achieved using Samsung products ARM7TDMI microprocessor core S3C4510B and DSP chip TMS320C5416 with high-speed, low power C54X of fixed-point General to implement the digital processing of multi-microprocessor structure, remote data transmission network chip is manufactured in Taiwan RTL8019AS Realtek Ethernet controller connected to the installation to meet the data acquisition, display and transmit real-time. usingμClinux for Embedded real time operating system platform with accomplish code-cut, commission and transplanting.The instrument is compact, lightweight and beautiful, smart to carry. |
