The Research for Wireless electrocardiogram Biosensor System
(0) Describe the wireless biosensor system for electrocardiogram (ECG), such as the way to increase the transmission distance and overcast area of signals in the complicated structure space; improve identification speed in multi-user wireless biosensor system; the wireless relay transport protocols; decreasing the power and volume of the biosensor. The basic method is adopting the wireless relay station communication; designing hardware address identification circuit; taking full advantage of the inner resources of single chip to substitute hardware circuit. Other method is designed an improved anti-collision model that is time-division multiplexing address (TDMA) with the inquiry priority based on broadcast in call number. By doing the research the results is that the biosensor signals figure is clear all over the same floor and the consumption current is less. The hardware address identification decreases the interruption times for single chip of the biosensor greatly; raises the quality of signal monitoring; the response time and accuracy of communication is improved.The volume of biology signal pre-treatment circuit is almost reduced to 40 percent and the power dissipation is also reduced obviously. Patients will take it with. It can work long or continuation and fixed-timing. The conclusion is that the system can meet the requirement in the same floor sickroom monitor and surgery monitor.
