<P>PROBLEM TO BE SOLVED: To provide a wireless bioinformation sensing system allowing long-time measurement with a compact battery by reducing power consumption. <P>SOLUTION: The wireless bioinformation sensing system includes: an integral control unit distributing a time reference; a plurality of measurement units receiving it; and an operation management unit managing operation conditions or times of the plurality of measurement units. The integral control unit receives signals from the plurality of measurement units, and demodulates, stores, transmits, and displays biosignals. The measurement unit includes an A/D conversion part, a data processing part, and a transmission/reception part, performs biosignal measurement according to the distributed time reference, and performs wireless transmission to the integral control unit. The operation management unit (1) starts the data processing parts of the measurement units, (2) starts the A/D conversion parts, and after the simultaneous measurement of the respective measurement units, (3) brings the A/D conversion parts and the data processing parts into power-saving states, (4) starts the data processing parts and the transmission parts in order of the priority of the measurement units, performs the transmission, and (5) brings the data processing parts and the transmission parts into power-saving states after the transmission. <P>COPYRIGHT: (C)2012,JPO&INPIT |
