Vehicular Multiple Physiological Parameters Acquisition And Transmission System Software Design And Implementation

With the rapid development of communication technology, computer technology and the coming of information age, makes an embedded system is a new hotspot in the field of electronic system design.Tightly integrated hardware and software, it will implement the "tailored" advantage for the user, has the very high cost performance and real-time characteristics.And, with the application of the embedded real-time operating system in many physiological monitoring, made the current medical instruments toward the direction of more intelligent and networked, further implement the medical information interaction between doctor and patient, to people’s life, study and work has brought great changes.At this point, this article first has carried on the system analysis and system architecture design.Embedded system usually all include the hardware platform and software development, software and hardware is complementary relationship, relying on each other.According to the development process of embedded system, which in turn tells the system requirements analysis, technical analysis of the system and the concrete architecture design of the system.Among them, the system architecture design generally includes: after the first hardware software, hardware and software and hardware after software collaborative design mode, etc.Secondly, in view of the present remote multiple physiological parameters acquisition and detection technologies related to some of the deficiencies, put forward a kind of based on embedded system and the Bluetooth technology vehicular multiple physiological parameters acquisition and transmission module of software and hardware, the design and implementation of the main research the multiple physiological parameters of transmission of the construction of the hardware platform, the transplantation of the Linux operating system, the design of the driver, the design of the Bluetooth communication and the design of the application.This plan is mainly in order to satisfy the multiple physiological parameters data remote monitoring system front-end to separate free wearable, short-range wireless networking, synchronous transmission and low power requirements, and on the basis of wireless body area network(WBAN), using the MSP430 with the Bluetooth 4.0 including ECG, bloodpressure, blood oxygen saturation of multiple physiological parameters, such as separate wireless sensor unit, designed the ARM9-based multi-parameter short-range together with the remote wireless transmission terminal, integrate it in the storage battery or car travel tools such as in order to facilitate users to carry, while provides a source of energy for the whole system.Finally, the designed system test, mainly including the system test environment and test results.In this paper, the designed system is mainly based on embedded technology, so the system test is to work in an embedded environment, and the experimental results in this paper, the embedded environment.Paper presents a vehicular multiple physiological parameters acquisition and transmission module of software and hardware structure of the overall design, based on embedded remote medical monitoring module is a fusion of multiple techniques in the integration of digital, intelligent, networking products, more suitable for remote home monitoring, gradually recognized and valued.This topic research has very important realistic meaning and medical value, and very broad market space.
