The calorie monitor
Technical field
The present invention relates to a kind of energy consumption of human body monitoring technology, relate in particular to a kind of calorie of monitor.
Background technology
Calorie is meant 1 gram water is promoted 1 degree centigrade of needed heat under 1 atmospheric pressure, is commonly used to now weigh and takes in the heat number that perhaps consumes human every day, but directly detect a calorie ten minutes difficulty, and not easy to operate.
In early days, people just adopt the way of meter step quantitative estimation in order to assess and measure the kinergety consumption problem of human body, and thus, pedometer just is applied to healthy and sports science by people.Pedometer, as the active a kind of instrument of a kind of assessment human body be 7, the eighties, perhaps occur more early the time, at the beginning of occurring, pedometer is to utilize the weight of machinery swing to promote stem-winder to walk about and realize, just as early stage stem-winder.Because the principle of frame for movement, pedometer at that time can only be worn between waist, and, wear according to a specific direction (vertically) direction.Afterwards, along with the development of MCU, the record of step number changed electronical record into, and showed through LCD, and still, any change does not take place meter step principle.Certainly; Because the application of MCU, people are not limited only to the record of step number, but on the meter basis in step, have increased the estimation of sports energy consumption; The method of estimation is to calculate walking distance according to measuring step number * stride, then according to the norm formula to calculating power consumption values (KCal) between distance and the energy consumption.Yet having now this is the technical scheme of the energy consumption of human body monitoring of representative with the pedometer, the actual energy consumption that can not measure human body accurately.
