A Portable Calculating Instrument For Abdominal Breathing

Abdominal breathing is an effective hypoxia exercise which can be realized easily. Directed towards this breathing style, a new low-power-consumption instrument for assisting physical exercise has been developed.After the function is analyzed, the system control scheme is put forward. The control part was analyzed and realized. And the outline structure of the system is designed. A new phonetic chip is applied to realize compound speaking, and a low-power-consumption LCD is adopted to realize display, which enable the system have a friendly man-machine interface. The portable system's development and application is discussed and the problem of how to realize low-power-consumption is analyzed, and the methods about how to realize low-power-consumption is taken out in this paper. The low-power-consumption management technique using in the paper makes the system low-power-consumption, and also gives some advice to the design of the portable and low-power-consumption system.The developed abdominal breathing calculating instrument reaches the function requirement and realizes the objective of low-power consumption.
