Even if the sport does not know how long their own campaign, how far away the road, as well as the number of calories consumed. Especially now with special attention to body weight for men and women every day and worry about how many calories to eat will not be excessive and so on. Because we know that exercise can be consumed by the body's heat, if the consumption of calories than to eat into the heat, you can achieve weight loss results. However, normal life, we can not calculate their calories consumed by the movement, but this use of Microchip's 16-bit single-chip dsPIC30F4011 digital signal as the control core, and use ST's 3-axis accelerometer LIS302DL, placed on the user's waist, or pocket, in the movement or walk to get acceleration data and angle, after digital signal controller operations to determine and discriminate between state of motion or action to determine a fall at the same time calculates the time in sports the distance, another most important feature not only be able to calculate the distance, the use of formula through a processor that can calculate the movement of the calories consumed by the number of users a clear understanding of the current consumption of energy, and learn to live their own health. At the same time as the electronic key device is also using RFID technology principles of radio frequency identification technology, go exercise, bunch of keys will be too, is a weight burden. With RFID technology, electronic key, while another with Microchip's KEELOQ technology, making access control management more secure. In addition, when a fall is detected, the system will issue a signal from the RFID wireless transmitter module to send signals to inform nursing station staff.
