Design of Wireless Communication Module of Human Physiological Parameters Acquisition System

Objective： Based on mobile intelligent terminal medical technology has become a hotspot in the research of the medical health care at ordinary times. Compared with traditional medical equipment system, intelligent terminal of mobile medical technology is a kind of low physiological and psychological load technology, intelligent terminal mobile medical system has small volume, low cost, low consumption, easy to carry such outstanding characteristics. In order to guarantee human physiological parameters acquisition system collected physiological parameters of reliable and efficient transmission to the intelligent terminal, this paper designed the wireless data transmission module in the physiological parameters acquisition system. Methods： the wireless communication module using bluetooth transmission mode, mainly including microprocessor periphery circuit and bluetooth chip peripheral circuit design. At the same time, considering the performance and data throughput levels as well as the transport protocol software overhead during execution. So the host control interface of bluetooth module in the human body physiological signal acquisition system used the UART interface. Results： at the same time in order to verify the function of the module, using the module to send human respiratory signal which FLUKE multi-parameter simulator MPS450 simulated, and using the intelligent terminal to receive data. Conclusions： The test shows that the whole circuit design is reasonable, works well, to be able to send human physiological parameters data of the human physiological parameters system collected. So the wireless communication module can meet human physiological parameters acquisition system based on intelligent terminal requirements.
