The Portable Physiological Signal Acquisition System Based On MSP430

Along with the development of The Times, the elderly population is gradually increasing, the physical condition detection is particularly important. Now testing equipment is relatively large, mostly is basically in large hospital or clinic treatment, the portable devices is proposed a new request. These devices can carry not only, more important is to perform real time detection to the body. This thesis is based on the above content.First of all, we know the development of portable devices at home and abroad, the advantages of foreign equipment, find out my own shortcomings, and on this basis to do our own improved and updated. Then we will design the content of the show. On the basis of the above, we to narrative of the functional requirements of the whole system, and then the physiological signal acquisition, signal collecting and processing of how are we to solve the problem. The plan implementation process of the whole system requires us to do further analysis. At the same time, the development of hardware design can be carried out. We are on the basis of understanding the design principle of hardware, with MSP430 single chip microcomputer for the development and control platform, and for further design. We made the simple introduction of single-chip processor, after understand these; we design the circuit structure of different. On the basis of the collected data of drive circuit design and signal processing circuit design and serial communication circuit design. These different circuit design will be transplanted into the physical map of hardware, we make to the whole circuit of the PCB, and physical display. In the hardware have been developed on the basis of, we design the software of the system. Must first understand the principle of software development and related technology, and then we based on the C language, complete the design of the data acquisition program. When after the data collection, data processing program and data transmission should be timely design is completed. Once the system’s hardware and software is completed, we will start debugging and testing. System if applied to the actual condition can appear a series of problems. We often appear problem, give some solution. Then the hardware and software were tested respectively.Upon completion of the above and for us to analyze the whole system on the basis of experiment, the results show that this system can complete data collection and rationality.
