Embodiment Construction

[0021] The present invention will be further described below through specific examples.

[0022] The present invention adopts the ADXL202E chip of ANALOG Company as the sensor chip 1, and the chip pin configuration is as follows Figure 4 shown. The chip can measure both dynamic acceleration and static acceleration. Measuring range: ±2g. The ADXL202E chip is built into the mobile smart terminal and connected to the microprocessor (μP) of the mobile smart terminal. The circuit of the ADXL202E chip is as follows: Figure 5 shown. The connection of the eight pins of the chip is: V DD Connect 3V to 5.25V power supply; V DD and COM indirect capacitance C DC Play the role of decoupling, C DC Recommended value 0.1μF; X FILT , Y FILT connected to capacitor C X , C Y , and by C X , C Y The value to set the bandwidth of the low-pass filter; T2 connected to the resistor R SET ;X OUT and Y OUT The outputs in the X and Y directions are connected to a timer / timer port of a m...

Abstract

The acceleration inducing energy consumption calculating pedometer has one mobile intelligent terminal with sensor chip, microprocessor and memory. The sensor chip senses the periodical walking pulses, the microprocessor counts the pulses and saves the date in the memory. The microprocessor can calculate the step of the walker, walking distance and heat consumption based on the weight and the pace the user inputs in advance. The present invention has the features of simple structure, high reliability, easy carrying, etc. and is one ideal intelligent terminal favorable to body building.

Description

technical field [0001] The invention relates to a device for measuring walking steps, actual walking distance and consumed calories by using a mobile intelligent terminal. technical background [0002] At present, the fast pace of modern urban life makes people's physical activity obviously insufficient, and their calorie consumption decreases, which leads to weight gain and physical decline. Walking exercise is a good way to increase calorie consumption and carry out healthy exercise. It does not require much time or a special venue, but it can easily achieve the amount of exercise required for health, and it helps strengthen the cardiovascular system Function, the purpose of promoting good health. On the other hand, today's various mobile intelligent terminals, such as PDAs, mobile phones, etc., have become an indispensable part of people's lives. Mobile smart terminal users can easily measure the number of steps they walk, the actual walkin...
